Description

FIELD OF THE INVENTION The invention relates to the paint industry, specifically to compositions for coatings that can be used to finish polyurethane foam shoe soles. A known composition for coatings containing polyetherurethane with hydroxyl groups and an isocyanurate hardener i. The components are mixed 30 minutes before application to the artificial skin and cured at 10 minutes or 2-3 hours at 40-50 ° C. The closest technical solution to the invention is a coating composition comprising a polyurethane binder, phenol formal CR -OCbNH-R -NHCOO-R-R glycerol residue; adipic acid residue phthalic acid residue, P. - toluylene diisoci residue. Nata / R - phenol residue; a residue of diphenylmethane-4,4-diisocyanate; polyalkylene glycol adipate residue, AND 1-3, and cyclohexanone and acetone as solvent and additionally alcohol and (or 1 acetone-soluble dye in the following ratio of components, wt.%: Polyurethane; binder 1.94-7.49 Phenol formaldehyde per resin, 07- 0.30 Polyvinylformalethylalene resin 0.07-0.27 Alcohol and (or) acetone-soluble dye 0.50-0.74 solvent Remaining Resin 101 - 1-tert-butylphenol and formaldehyde products in an alkaline medium used as a phenol-formaldehyde resin .: As polyvinylformal t pitch resin uses resin - a product of acetylation of polyvinyl alcohol with formaldehyde and acetaldehyde. As an alcohol and / or acetone soluble dye, 6 are used with a dehydric resin, polyvinyl form lethylaline resin, solvent C23. which melt at 100 ° C. The aim of the invention is to reduce the curing temperature and shorten the drying time of the coating. The objective is achieved in that a coating composition comprising polyurethane binder, phenol-formaldehyde resin, polyvinyl formalmethyl-alkyl resin, solvent, as polyurethane binder contains polyurethane of the general formula -R-OCQNH-R-V4HCOO-R) vi OCONH-R-R-OCQNH-R-V4HCOO-R) OCONH-R-R-OCQNH-R-V4HCOO-R) OCONH-R-R-OCQNH-R-V4HCOO-R R.-Ori-C 33iNo-34 dye-colourants based on naphthalene and benzene in the form of metal complexes with C and Co. The formulation of the proposed composition is presented in Table. 1. The properties of the coatings according to the invention and the known solution are given. The proposed and known properties of the coatings are presented in table. 2. Water resistance is determined as follows. Coatings are applied to metal plates and cured according to the regime given in Table 2. 2, and then kept in water for 1 hour. The + sign means that after the tests, dull patches did not appear on the film. Adhesion is determined as follows. On the plates prepared as indicated above, the blade was cut with a lattice cuts through 1 mm. Then, the incisions are sticky, pressed and sharply torn off. The + sign means that no particles of a varnish film were detected on the tape, which indicates good adhesion. Thus, the proposed composition has a low curing temperature and accelerated drying, which makes it possible to use this composition for decorative finishing of polyurethane foams on existing automatic lines.
