MODIFICATION OF ALKYD RESINS WITH FUNCTIONALIZED DIENE LIQUID RUBBERS TO CREATE POLYMER COATINGS WITH IMPROVED PROPERTIES<\/strong><\/p>\n N.V. Hudzenko,<\/strong> Polym. J., 2022, 44<\/strong>, no. 2: 128-136.<\/p>\n Section: Structure and properties.<\/p>\n Language: Ukrainian.<\/p>\n Abstract:<\/strong><\/p>\n Modification of existing paints and varnishes based on alkyd and melamine alkyd resins as well as creation of new film formers with the help of functionalized oligomers in order to improve the properties of materials during their operation was carried out. Liquid oligobutadiene rubber with end hydroxyl groups, HTPB trend mark was used . Pentaphthalic varnish PF-060 and melamine-formaldehyde resin K-421-02 was modified by triisocyanate oligobutadiene rubber based on trimethylolpropane and isophorone diisocyanate resin in different ratios.<\/p>\n Analysis of the FTIR spectra of the developed paints and varnishes showed that the process of polymerization in a thin film in air forms a spatially crosslinked polymer and passes through the stage of formation of branched soluble polymers, followed by copolymerization of components with oxygen and formation of structured solid polymer.<\/p>\n The optimal content of rubber in the modified paints and varnishes was estimated. For alkyd varnish PF-060 it equals 10 wt.% and for melamine-formaldehyde resin K-421-02 is in the range 7-10 wt.%. Addition of triisocyanate accelerates the drying process of coatings on air, high values of surface hardness, adhesion, resistance to bending and water absorption were also received.<\/p>\n Developed modified paints and varnishes are characterized by increased viability, shelf life of more than 6 months, homogeneity. Proposed scheme allows to obtain transparent coatings with high physical and mechanical characteristics and can be recommended for practical use in various coating technologies.
