    tends to become porous over time losing its hydrophobic properties, so
    it has to be renewed every so often involving high costs not only for its short
    period of life but, also, because the wind turbine has to stop during the
    corresponding works. On the other hand, the increase in hydrophobicity leads to
    5 a reduction in adhesion forces, which implies that problems of
    adhesion of the paint to the surface of the shovel.
    Anti-ice paints for wind turbine blades are described, for example, in
    ES2230913T3 and GB246367SA.
    On the other hand, high solid paints ("HS Paints") are also known for
    1 o paint wind turbine blades. These paintings are two component paints, a
    first component based on polyurethane, that is, mixtures comprising
    basically synthetic polyurethane resins, organic solvents and pigments, with a
    solids content> 70% by weight, low density (1.2 -1, 4 g / cm3), a content in
    volatile organic compounds ("VOC") <300g / 1, and a second hardener component
    fifteen based on isocyanates, which is mixed with the first component before the blades are painted.
    The paints thus obtained are cured and dried outdoors and form coatings that
    meet the highest requirements to the stability of brightness and color even in climates
    extremes They are also highly elastic, weatherproof, abrasion resistant, such as
    for example caused by wind and / or rain, scratches, solvents, agents, oils
    2 o hydraulic, etc., so it is widely used in paints to coat blades
    wind turbines However, the hydrophobic properties of these paints are
    limited, so they are not effective against icing.
    Such high solids paints are marketed for example by companies
    German BASF COATINGS GMBH (RELEST® line) and MANKIEWICZ GEBR. & CO. (line
    25 ALEXIT®).
    It was therefore desirable to obtain a paint that had properties tending to
    avoid the formation of ice on wind turbine blades without reducing resistance to
    the physical and chemical agents conferred by conventional paints used as
    wind turbine blade coatings, especially resistance to UV radiation
    3 o And resistance to erosion, both in terms of particle erosion and
    erosion by rain.
    DESCRIPTION OF THE INVENTION
    The present invention aims to overcome the drawbacks of the state of the
    35 technique mentioned above by means of a novel anti-ice paint
    wind turbines, a procedure for obtaining this anti-ice paint, the use thereof, and a shovel at least partially coated with such anti-ice paint.
    5 10 15 2 O The anti-ice paint according to the invention comprises an anti-ice base component comprising a main component of a high solids paint, which may itself be conventional, with a binder component based on synthetic polyurethane resin dissolved in a solvent. organic main and a hydrophobic component comprising hydrophobic anti-ice functional nanoparticles selected from nanoparticles functionalized with a polymer and sol-gel functionalized nanoparticles, the anti-ice paint being characterized in that the anti-ice paint comprises a mixture of the main component with a dispersion of functional nanoparticles dispersed in a dispersing composition comprising the main solvent and a dispersant, the dispersing composition forms a base matrix; the dispersing composition and the functional nanoparticles form a dispersion of nanoparticles in which the functional nanoparticles are in the base matrix; The dispersing nanoparticle dispersion is mixed with the main component forming an anti-ice base component of the anti-ice paint.
    In the present description, the following terms are used to define what is indicated below:
    25 Main component: Paint component without functional nanoparticles;
    30 Main component: component of the high solids paint comprising, in a conventional manner, the binder component dissolved in a main solvent;
    Main solvent: Main solvent present in the main component;
    35 Nanoparticlesfunctional:nanoparticlesfunctionalanti-ice
    selected from nanoparticles functionalized with a polymer and
    sol-gel functionalized nanoparticles, so that they are hydrophobic
    anti-ice;
    5 Dispersant composition: composition comprising the solvent and the
    dispersant that forms the base matrix for functional nanoparticles;
    Nanoparticle dispersion: dispersion comprising the
    functional nanoparticles in the base matrix;
    10
    Anti-ice base component: mixture comprising the component
    Main and dispersion of nanoparticles - when the anti-ice paint is from
    a single as component, the term "anti-ice base component" is
    equivalent to "anti-ice paint" while when it comes to a paint
    fifteen anti-ice of two or more components, the "anti-ice base component"
    corresponds to the primary component.
    When the anti-ice paint is a two component paint, the anti paint
    ice includes, in addition to the anti-ice base component as the primary component,
    2 o a hardener component selectable between hardeners based on
    iso cyanates, polyisocyanates and combinations thereof, as a component
    secondary
    The fact that, according to the invention, the anti functional nanoparticles
    25 ice have previously dispersed in the dispersant composition that forms the
    base matrix that has a composition at least similar to the main component of the
    high solid paint, allows to introduce, disperse and distribute nanoparticles
    functional anti-ice in the main component more homogeneously and effectively,
    that when functional nanoparticles are introduced directly into the
    3 o main component, so that the anti-ice paint according to the invention
    maintains at all times the physicochemical properties of a paint
    conventional used to coat wind turbine blades, especially the
    resistance to erosion and ultraviolet radiation, guaranteeing the same durability
    and aging resistance than the original paint. In this way, the composition
    35 dispersant acts as a "Trojan Horse" for functional nanoparticles, which
    allows dispersing functional nanoparticles in the main component of the
    high solid paint.
    The dispersant composition may comprise the main solvent and the
    5 dispersant in a ratio of 1: 2 by weight, preferably 1: 3 by weight,
    while the nanoparticle dispersion can comprise 20-30% by weight,
    preferably 25% by weight of nano functional anti-ice particles.
    The anti-ice base component may comprise the dispersion of
    nano particles 4-6% by weight of functional nanoparticles.
    10 When it comes to a two-component paint in which the component
    Main is a conventional high solid paint, the anti-ice base component is
    you can mix with the hardening agent so that the final anti-ice paint
    Have 2-3% of functional nano particles.
    fifteen The main solvent may be selected from solvent based
    alcohol as an organic base, common in polyurethane chemistry by themselves
    such as butyl acetate, ethyl acetate, 1-methoxy-2-propyl acetate, toluene,
    xylene, naphtha solvent, 1,4-dioxane, diacetonic alcohol, N-methylpyrrolidone,
    dimethylacetamide, dimethylformamide, dimethylsulfoxide or discretionary mixtures of
    2 o said solvents. According to the invention, the main solvent may be a
    medium polar organic compound, preferably n-butyl acetate since this
    The latter is the most common in conventional high solids paints based on
    polyurethane resin for wind turbine blades. Such conventional paints to
    Polyurethane resin base are marketed, for example, by companies
    25 German BASF COATINGS GMBH (RELEST® line, for example RELEST WIND 1306) AND
    MANKIEWICZ GEBR & CO. (Ifnea ALEXIT®, for example ALEXIT 495-498).
    The dispersant in the dispersant composition may be a dispersant
    polymer of non-polar systems, such as an amphiphilic polymer dispersant, such as
    3 o for example a polymer dispersant of non-polar systems.
    In one embodiment of the invention, the dispersant is a polymeric dispersant.
    cationic which may comprise a mixture of alkyl esters, fatty acids and
    alkylamines Suitable dispersants of this type are, for example, those belonging
    to the HYPERMER KD-3 line marketed by the British company CRODA
    35 INTERNATIONAL PLC

    Some examples of inorganic hydrophilic nanoparticles used for the
    Development of functional anti-ice nanoparticles are those based on oxides and lu
    10 mixed oxides, including oxide hydrates of at least one metal or semi-metal
    of the main groups two and six, and transition groups one to eight of the System
    Newspaper of the Chemical Elements or of the lanthanides, especially oxides
    and mixed oxides, including oxide hydrates, selected from the group of
    Si, Al, Ti, Zr, and Ce elements. Examples of such inorganic hydrophilic nanoparticles
    fifteen they are SiOz-based nanoparticles, for example, pyrogenically prepared silica or
    colloidally, silicates, Alz03, aluminum hydroxide, aluminosilicates, TiOz, titanates,
    ZrOz, or sirconatos, CeOz.
    As compounds having hydrophobic groups, it is particularly preferred

    2 o alkyl having 1 to 50 carbon atoms, in particular having 1 to 10 atoms
    of carbon, and that has at least one hydrolysable group and at least one group
    OH and an NH group. Examples of compounds that have hydrophobic groups are
    alkyl alkoxysilanes, especially dialkyl dialkoxysilanes, and alkyltrioalkoxysilanes,
    preferably trialkylchlorosilanes, and dialkyl dichlororosilanes, alkylpolysiloxanes,
    25 dialkylpolysiloxanes, and alkyldisilozanes and the like.
    Compounds having hydrophobic groups are also suitable
    several monomeric and oligomeric silicic esters having methoxy, ethoxy or
    n-proposi and isopropoxy and which have an oligomerization degree of 1 to 50, in
    particularly from 2 to 10, preferably from 3 to 5.
    3 o As compounds having hydrophobic groups, it is especially preferred
    use dimethyldichlorosilane and hexamethyldisilazane and octyltrimethoxysilane and 1o
    dimethylpolysiloxane. Particularly preferred hydrophobic nanoparticles are
    nanoparticles based on the reaction products of SiOz and dimethyldichlorosilane and
    hexamethyldisilazane, especially SiOz reaction products and
    35 dimethyldichlorosilane. Examples of hydrophobic nanoparticles that can be used
    They are usual products sold, by the German company EVONIK INDUSTRIES, under
    AEROSIL® trademark, especially AEROSIL® 8200, Rl06, R202, R972,
    R972V, R974, R974V, R805 or R812, or by the company WACKER CHEMIE AG, under the
    Trademark or designation of type HDK, especially HDK H15, H 18, H20, H30 or

    preferably have an average particle size between 100 nm and 300 nm and, more
    preferably, its size is 150 nm to 280 nm.
    The average particle sizes and their distribution in the anti base component
    Ice are determined by laser Doppler velocimetry. To determine the
    2 o distribution of dispersion particle sizes uses a Z-SIZER device
    MODEL NANO ZS90 from MALVERN. To carry out the measurements use cuvettes of
    glass. Three samples of each suspension are prepared, 3 measurements are made of each
    shows and calculates the average of the values. So that the team measures are
    reliable concentrations have been determined by previous tests
    25 0.10 / 0 weight suspension. Zaverage and PdI values are measured (index of
    polydispersity).
    Zaverage is average Z-size or average Z-size. It is a parameter used in the
    dynamic light scattering, also known as cumulant mean. Is the
    main and more stable parameter produced by the technique. It is the best value for
    3 o report on quality control studies, as defined by ISO 13321 and
    ISO 22412. The latter defines the Zaverage value as "the average diameter of
    particle averaged from harmonic intensity. "
    The PdI value indicates the degree of variation or amplitude of a Gaussian bell
    which represents the distribution of particle sizes.

    The procedure for obtaining an anti-ice paint according to the invention
    includes identifying the main component of the high solids paint in which
    base the anti-ice paint, and prepare the anti-ice base component by
    a first step comprising mixing the dispersant with the solvent
    5 main to obtain the dispersant composition with a ratio
    solvent dispersant of lj3
    a second stage comprising mixing the dispersant composition with the
    functional nanoparticles, to obtain a dispersion of nanoparticles that
    comprises 20-30% by weight, preferably 25% by weight, of nanoparticles
    10 functional.
    a third stage comprising mixing and homogenizing the dispersion of
    nanoparticles with the main component to obtain the anti base component
    ice with content of functional nanoparticles from 4 to 6% by weight, preferably
    5% by weight, in which the nanoparticles have an average particle size between
    fifteen 100 nm and 300 nm, preferably from 150 nm to 280 nm.
    When it comes to getting a two-component anti-ice paint, the
    method further comprises a fourth comprising mixing the component
    anti-ice base than with the standard hardener component, as directed
    manufacturer. The nanoparticles remain in a proportion 2-3% by weight with respect to
    2 o the painting.
    This procedure allows to confer to a standard paint of shovels of
    wind turbines anti-ice properties, keeping intact the rest of their
    physicochemical properties and their durability,
    In a preferred embodiment of this process, the main solvent is
    25 n-butyl acetate, the dispersant is a cationic dispersant comprising a mixture
    of alkyl esters, fatty acids and alkylamines, and functionalized nanoparticles
    with pyrogenic silica nanoparticles functionalized with hexamethylsilazane or
    dimethyldichlorosilane.
    Such pyrogenic silica nanoparticles functionalized with
    3 o Hexamethyldisilazane (HMDS) are hydrophobic, have a spherical shape and 8 to 30 nm of
    diameter.
    Pyrogenic silica is a hydrophilic compound, with very fine Si02 particles
    with a specific surface area of 110 and 220 ± 20m2jg. The size distribution of
    particles of a typical silica smoke is <0.5 microns, with an average diameter
    35 generally between 0.1 and 0.2 microns
    generally between 0.1 and 0.2 microns
    Hexamethyldisilazane ("HDMS") is an organosiliconized compound,
    hydrophobic, of molecular formula [(CH3) 3Si] zNH which polymerizes on the
    silica nanoparticles, which are hydrophilic by their chemical nature, to
    5 convert them into hydrophobic molecules. This is what is known as "core particles
    shell "(" core-frame "): the core is the silica nanoparticle, which confers the shape
    and the base properties, and the framework is the HDMS, which confers the properties
    superficial to the functionalized nanoparticle.
    This type of functionalized nano particles is commercially available,
    10 for example under the names AEROSIL 300, AEROSIL R812 and AEROSIL R972 of
    the German company EVONIK INDUSTRIES. For example, the AEROSIL R812 presents a
    BET specific surface area of 110 + 20 m2 / g and an average particle size of about 25
    nm.
    For application to the wind turbine blade, the anti-ice base component is
    fifteen can mix with a hardener component selected from agents
    conventional hardeners based on isocyanates, polyisocyanates and
    combinations thereof.
    The invention also relates to the use of the anti-ice paint above.
    2 o described to cover at least a part of a wind turbine blade. It can
    cover only parts of the blade, such as the parts most exposed to
    cold temperatures, such as the leading edge and / or its radial end part, or
    It can cover the entire blade.
    Likewise, the invention relates to a wind turbine blade that is in
    25 part or completely coated of the anti-ice paint described above.
    It has been found that the anti-ice paint according to this
    invention has better properties than high solids paints of
    Conventional polyurethane as it not only confers hydrophobic properties but also
    3 o It also gives it resistance to erosion and aging. It must be so
    to be able to use it in wind turbines without having to re-certify them. In
    As for color, brightness, hardness, flexibility, UV resistance, ... the properties of the
    anti-ice anti-ice paint are similar to the properties to paints
    conventional high solids based on polyurethane, but the great advantage is that the
    35 anti-ice paint, according to the present invention, in addition to conferring the anti effect
    ice because it has less surface energy, is that it confers erosion resistance
    better than conventional high polyurethane solid paints, being the
    erosion resistance one of the most important properties in the blades of a
    wind turbine because it directly affects performance (erosion modifies the profile
    5 aerodynamic of the blade and lowers the performance) and because it directly affects the
    maintenance costs since, when it erodes the wind turbine must be stopped, and
    repaint the blades.
