Abstract

The invention discloses hydroxyl acrylic resin which comprises, by weight, 25-35 parts of toluene, 5-10 parts of butyl acetate, 20-30 parts of methyl methacrylate, 5-10 parts of butyl acrylate, 3-8 parts of butyl methacrylate, 3-8 parts of hydroxypropyl methacrylate, 8-15 parts of functionality polyester resin, 1-2 parts of functionality mixed addition catalyst and 5-10 parts of P-120 carbon 9 petroleum resin. The functionality polyester resin comprises, by weight, 5-10 parts of glycol, 30-40 parts of neopentyl glycol, 50-55 parts of adipic acid and 5-10 parts of fumaric acid and is obtained through esterification synthesis by using a high temperature melting method and diluted by using toluene. The functionality mixed addition catalyst is mixture of 8-12 parts of peroxide 2-ethylhexoic acid tert-butyl ester, 20-30 parts of azobisisobutyronitrile, 50-60 pats of peroxide teriary butyl and 10-15 parts of tert butyl perbenzoa. The hydroxyl acrylic resin has good adhesion when directly coated on nylon materials.

Description

technical field [0001] The invention relates to a resin for coating, in particular to a hydroxyl acrylic resin suitable for coating engineering plastics such as nylon or nylon plus glass fiber and a preparation method thereof. Background technique [0002] In recent years, the plastics industry has developed rapidly, and nylon products are increasing day by day. How to make the appearance and surface properties of these products reach a higher level, the industry usually uses the surface finishing technology of plastic products to meet these higher requirements. It is precisely because of the wide application of modified nylon that the surface adhesion properties of nylon materials are also different. Especially the nylon modified with glass fiber often needs surface treatment, but due to the low polarity of the surface of glass fiber nylon and the crystal structure, it is difficult to attach paint and coatings, and it is insoluble in any solvent, making the coating film Di...
