    The invention relates to the preparation of compositions for gluing a plastic coating to a metal base, in particular for gluing a polyamide coating to a metal base.
    A known composition for bonding a polyamide coating with a metal base, containing polybutadiene with a content of 90% 1,2-units and an organic solvent.
    However, the composition does not provide sufficient bonding strength.
    Closest to the proposed technical essence and the obtained result is a glue composite containing polybutadiene, water and target additives. 23 The disadvantage of the known composition is that the adhesion strength between the polyamide coating and the metal base is not fully satisfactory.
    The aim of the invention is to increase the adhesion strength of a polyamide coating to a metal base.
    This goal is achieved by the fact that the adhesive composition containing polybutadiene and water contains liquid polybutadiene containing 72% by weight of c-1,4-units as polybutadiene on 27 May. (Wcl, 4r-units and 1 wt.% 1,2-units, with a dynamic viscosity of 780 MPa-s and additionally an emulsifier - oXYL- or NOYIL polyoxy-ethylene ether

    WaterEverything
     The proposed composition is prepared by simply mixing the ingredients.
    Example. A 1-mm-thick iron plate sprayed with trichlorethylene and sand-treated was sprayed with a composition containing 50% by weight of liquid polybutdiene with a dynamic viscosity of 780 mPa-s containing 72%, 4-I "c-units, 27%, 4- and / CrC units, 1% 1,2-units, 2.5 wt.% polyoxyethylene octylphenol ether with 8 ethylene oxide units (octylphenol-ethoethyl acetate) and 47.5 wt.% water, are then calcined in 5 minutes and put into oxygen ,
    coating a) of polyamide 12, 5) of polyamide 11.
    A cross-cut is made to determine the adhesive strength of the specimen. In this section, a 6 mm recess is made with the help of the Erikna cutter. Then, using adhesive tape, the coating is tried to be removed. o and the case (f coating does not use adhesive tape at all, which means 100% adhesive strength. After storing the sample in warm water with a temperature or in a hot 3% solution of coarse detergent at a temperature of 90 ° C for 500 hours, the adhesive strength is 10 0%.
    EXAMPLE 2 An example is repeated with the difference that it uses a composition containing octylphenol oxyethylate with 8 ethylene oxide units in an amount of 4% by weight. The content of liquid polybutadiene is 50% by weight, and the water content is 48.6% by weight.
    EXAMPLE 3 An example is repeated. The difference is that a composition containing liquid polybutadiene in an amount of 20% by weight is used. The water content is by weight.
    EXAMPLE 4 An example is repeated with the difference that a composition containing 2.5% by weight of nonylphenoloxyethylate with 8 ethylene oxide units is used.
    EXAMPLE 5 An example is repeated, with the difference that a composition containing 4 May.% Nonylphenol and ethylene is used with 8 ethylene units. The content of liquid polybutadiene is 50% by weight, and the water content is 48.6% by weight.
    PRI me R b. An example is repeated with the difference that a composition containing 20% by weight of liquid polybutadiene, 2.5% by weight of nonylphenoloxyethylate and 77.5% by weight of water is used.
    PRI me R 7 (comparative). Example 1 is repeated, with the difference that a composition containing 50% by weight of a copolymer of butadiene and styrene, 47.5% by weight of lacquer gasoline and 2.5% by weight of 2-mercaptobenzimidazole is used.
    Exam e r 8 (comparative).
    On a metal sheet I spray the composition by the famous drug. After 400-hour storage of samples a and g in hot water with a temperature of 90 ° C, a decrease in adhesive strength by 25% is observed.
    Example 9 (comparative).
    An example is repeated with the difference that a composition is used which, instead of 2.5% by weight of octylphenoloxyethylate, contains 2.5% by weight of methylphenoloxyethylate.
    Data on the adhesive strength of the coating are summarized in the table.
