    (5) GLUE COMPONENTS
    The invention relates to aqueous resinous compositions, more specifically relating to storage-stable thermosetting phenolic compositions that can be used in shakes or primers to combine natural or synthetic elastomers with rigid or hardened non-rigid materials.
    It is known to use adhesive systems for combining natural and synthetic elastomers with such e or various elastomer, as well as with non-rigid and other rigid materials, including metals, natural and synthetic organic or non-organic and fibers and similar substances. . To meet the practical needs associated with combining olastomers with 30 rigid or non-rigid materials, a number of adhesives have been proposed. However, there was no uniform composition that would allow obtaining optimal results in all cases, Sft
    Adhesives for bonding elastomers to rigid materials are organic substances in a solvent, i.e. adhesive components, including film-forming components, dissolved or dispersed in organic solvents. Solvent based adhesives are used in smaller quantities to bond elastomeric materials with non-rigid materials, especially cHHTeTM4ecKHFi fibers.
    However, the use of adhesives and solvents based on solvents is associated with certain complications. One of the most serious drawbacks is the high cost of solvents, which often cannot be regenerated without the use of an unacceptable expensive extraction system. Another complication associated with the use of solvent-based adhesive formulations concerns the safety of the environment, occupational safety and the safety of the consumer product. While the last two requirements apply to any adhesive compositions, the limitations associated with environmental protection relate mainly to solvent-based adhesive compositions regarding their type and amount of their release to the atmosphere. The use of water-based formulations, i.e. those in which the adhesive components are dissolved or dispersed in water are associated with less complications with regard to environmental protection than solvent based formulations. Aqueous adhesive compositions are known, but they are used exclusively in cases where at least one material is porous or capable of adsorbing water, and which are not so hydrophobic as to impair or break the bonding of the first adhesive film altogether. Solvent-based adhesive compositions that are in greatest demand in the industry for combining elastomers are characterized by long-term storage stability, i.e. they can be stored for indefinite periods without gelatinization or loss of adhesiveness; they have good film stability; more precisely, parts can be coated with wet glue, dried and stored for indefinitely long periods of time without significant loss of adhesive properties, and the glue is thermosetting. e. the active adhesive materials remain substantially inert until the bound system is heated to the temperature at which the compound should occur. Particular preference is given to such adhesive compositions that meet these requirements and which also provide an adhesive bond that is resistant to adverse environmental conditions. The closest technical result and the achieved result to the proposed adhesive composition is an adhesive comprising a phenolaldehyde novolamny resin, a hardener and water, which has an adequate adhesiveness Tlj. Such compositions, as a rule, have insufficient stability. For example, even the best known aqueous formulations should be applied within two weeks after preparation, since when this period expires, gelatinization and / or adhesive loss occurs. There is a need for aqueous adhesive compositions that are stable for long periods of time, retain their efficacy during storage, and have adhesive properties comparable to commercial solvent based adhesive compositions. The purpose of the invention is to increase the stability of the adhesive composition during storage. The goal is achieved by the fact that the adhesive composition, including oenolaldehyde nuy Novolac resin, hardener and water, contains Z-polyoxymethylene dimethyl or p-polyoxymethyleneisopropyl methyl ester as the curing agent at the following ratio of components, weight, h: 4% phenol aldehyde resin and resin, and resin. WaterUp to 2 - 40% concentration of adhesive composition. In contrast to such known adhesive compositions, the proposed aqueous adhesive compositions have a long-term stability when stored during an environment. zhayuschey temperature and cured at elevated temperatures, i.e. they are thermosetting. This allows adhesion bonding, which in terms of adhesive strength and resistance to adverse environmental effects is comparable to solvent based adhesive systems. In addition, the compositions have good film properties, are resistant to scraping and flow, and are applied as a single layer of glue or soil (in combination with an layer of elastomeric glue) to bond vulcanized natural and synthetic rubbers with hard or non-rigid materials. Phenolic resins are selected from the group consisting of thermoplastic condensation products of phenol and aldehyde, usually referred to as 1 phenolic novolac resins. Such resins are made according to well-known methods for the condensation of enols and aldehydes, usually acidic. or neutral conditions, wherein the Oenolic compounds in the reaction mixture are in amounts greater than stoichiometric. The novolac resins include the reaction products obtained by the subsequent condensation of a resole resin with an additional phenolic compound. Acceptable resins include resinous oils and pulverized solid materials. Novolac resins are materials that melt for a long time and do not go into a non-melting cross-linked state with a single heating. Novolac resins can turn into a non-meltable state by adding a crosslinking agent such as a methylene donor.
    In the preparation of Lenol novolac resins, various phenolic compounds, such as monoxides and polyoxyphenols, can be used, including such compounds that contain at least one aromatic nucleus and their substituted derivatives, and mixtures of these phenolic compounds. other phenol compounds may include alkyl, alkoxy, amino, and
    etc. Examples of phenolic compounds without their limitation include phenol, para-tert-butylphenol, para-i-nylphenol, para-chlorophenol, para-alkoxyphenol, ortho-cresol, meta-cresol, ortho-chlorophenol, meta-bromophenol, 2- ethyphenol, amylphenol, nonylphenop, cashew nut husk liquid, resorcinol, orsin, phloroglucin, pyrocatechin, pyragolol, silicic acid, 6iiic-0e NOL-L, bis-phenol S, etc. Particular preference is given to such new resins, which are obtained using a mixture of phenols, including 100 mol.% Of at least one polyoxyphenol, such as resorcinol, phloroglucin, 1g of halopole and the like, with resortium being the most preferred (a); from about 50 to 98 preferably, from about 60 to 98 mol. at least one polyoxyphenol and from about 50 to 2, preferably from about kO to 2 mol at least
    one monoatomic phenol, the core of which is not substituted by a hydrocarbon radical, i.e. a radical that contains only carbon and hydrogen atoms, although the cores can be 6 "substituted by such groups as alkoxy, amino, halide, etc. (b) / from about 10 to 98, preferably from about 50 to 98 mol, of at least one polyoxyphenol and from about 90 to 2, preferably, from about 50 to 2 mol.% of a monoatomic phenol, of which at least one alkyl group has a core as a substituent with the number of carbon atoms from 1 to 22 (c); 100 mol.% Of at least one monoatomic phenol, the core of which is substituted by at least one alkyl group with 1 to 22 carbon atoms, and the indicated molar percentages are determined based on the total amount of the phenolic compound 1 and. To obtain the modified novolac resins by | Ejection of previously obtained phenolic resole or phenolic novolak with another phenolic compound, it is advisable to choose the latter from the group consisting of multi-monomeric phenols, the cores of which are replaced by at least one alkyl g eupa containing from 1 to 22 carbon atoms (g).
    Examples of aldehydes which can condense with phenolic compounds Messrs to form novolachg GOVERNMENTAL resins can serve without limitation formaldehyde, acetaldehyde, propionic aldehyde, isobutyric aldehyde, 2-ethylbutyraldehyde, 2-metilpentaldegid, 2-etilgeksaldegid, as well as compounds which during decomposition, formaldehyde is given, such as para-formaldehyde, trioxane, furfurol hexamethylenetetra 1H, acetals, acetals, which in 1 | melts formaldehyde when heated, bemetaldehyde, and the like.
    The proposed compounding compositions are water-borne compositions, i.e. the individual components are soluble or dispersible in water by or by adding small amounts of organic solvents that are miscible with water in a wide range, i.e. mono- and dialkyl ethers ethylene glycol ethylene glycol, propylene glycol, isopropylene glycol, n-butylene glycol, diacetone alcohol, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl keto and the like. Waterborne adhesives may contain other well known additives, S including plasticizers, fillers, colorants, enhancers, and the like, and these substances are taken in the amounts commonly used in the practice of making glue. When preparing adhesive compositions, it is advisable to use the novolac phenolic resin in a dissolved form in water or, if it is not soluble in water, use the resin in a state dispersed in water, preferably in the form of an emulsion, prepared in accordance with standard practice. The remaining components can be mixed into the aqueous novolak composition in any order and by any standard means, allowing to obtain a final homogeneous solution or dispersion of adhesive materials in water. Preferably, the solid insoluble materials are finely ground, which allows to obtain a coloidal adhesive composition. The resulting aqueous compositions are stable when stored at ambient temperature, thermosetting, i.e. harden when heated. Compositions are also characterized by excellent durability against scraping, i.e. the compositions can be applied to materials, dried and left in a dry and uncured state for a long time, and then cured with heat. With npj. .- "Enhancement of the Adhesive Compositions Available. They can be applied either to one or both of the glued surfaces in any standard manner, for example by rolling or using a brush, drying and then curing by exposure at elevated temperatures, such as those commonly used in vulcanization of natural and synthetic rubbers and preferably D range from about 135 to 235 ° C. The proposed adhesive systems can be used for the direct bonding of natural or artificial rubbers with various rigid and / or non-rigid materials, including metals, natural and artificial organic or inorganic fibers, and similar materials. The described adhesive systems can also be used as priming compositions for treating rigid or non-rigid materials in combination with both water-based and solvent-based rubber. In addition, the proposed adhesive systems can be combined with latexes, such as vinyl pyridine rubber, to produce RFL adhesives -Types for combining fabric with rubber and which provide a strong adhesive bond and, in addition, significantly increase the duration of work. In addition to the surprisingly good storage stability, the compositions provide the required properties of the films, are resistant to scraping and flow when used as either a primary single-layer adhesive, for example, for directly joining rubber with metal, or as a two-layer material, i.e. The adhesive system is applied to the rubber as a primer and is extremely resistant to adverse weather conditions.

Curing is carried out at for lO min. The specimen is subjected to an adhesion test, resistance to the action of bales of water and resistance to hot oil. The adhesion failure is determined in accordance with ASTM D k2S, method 5, modified with respect to temperature. The tests for resistance to boiling water are carried out by immersing the test samples in boiling water for 2 hours. The rupture is determined by peeling rubber from the metal during rolling immediately after removing the sample from the water. These tests are more stringent than standard tests, according to which the samples are cooled to room temperature before peeling. Resistance to the effects of hot oil is determined by immersing the samples in ASTM-1 oil for 7Q hours while cooled; sample to room temperature, wiping it off the oil and peeling off the rubber from the metal using rolling devices. In each case, a breaking force is determined to separate the rubber (100 R). The composition has the same efficacy after storage for 6 weeks at. Virtually no changes in the appearance or viscosity of the compositions occur after aging for 6 months at 51 C. In the case when, in the described adhesive, J-polyoxymethylene dimethyl ether was replaced with para-formaldehyde, the resulting composition was gelatinized upon standing overnight. Example 3.
