Problems solved by technology

But at present, most coatings are difficult to adhere to some alloys (such as magnesium-aluminum alloy, zinc-aluminum alloy), stainless steel and glass products. In order to improve their adhesion, in the traditional coating method, an adhesion promoter must be added, but This method has problems of poor paint storage stability and poor paint film adhesion durability. It will not be very long; at the same time, it will also make the adhesion of the coating film better in the early stage and worse in the later stage

Abstract

The invention discloses high-adhesion thermoset acrylic resin which comprises, by weight, 18-25 parts of dimethylbenzene, 5-10 parts of n-butyl alcohol, 8-13 parts of methyl methacrylate, 15-20 parts of ethyl methacrylate, 8-13 parts of methacrylic acid ethyl ester, 15-25 parts of styrene, 8-15 parts of functionality polyester resin, 0.8-1.5 parts of functionality mix addition catalyst and 0.8-1.5 parts of grafting couplant. The functionality polyester resin comprises, by weight, 28-33 parts of neopentyl glycol, 12-17 parts of trimethylolproprane, 5-10 parts of adipic acid and 40-50 parts of isophthalic acid and is obtained through esterification synthesis by using a high-temperature melting method. The functionality mix addition catalyst is mixture of 8-12 parts of peroxidation 2-ethylhexoic acid tert-butyl ester, 20-30 parts of azobisisobutyronitrile, 50-60 parts of peroxidation tertiary butyl and 10-15 parts of tert-butyl perbenzoa. Phenomena of layering, pig skin and livering can not occur during storage and construction of paint made from the high-adhesion thermoset acrylic resin, and good adhesion is achieved when the paint is directly coated on a base material hard to attach.

Description

technical field [0001] The invention relates to a resin for paint, in particular to a thermosetting acrylic resin with high adhesion and a preparation method thereof. Background technique [0002] Various hardware workpieces and glass products are widely used in daily life due to their respective advantages. In order to improve its surface decoration and protection, it is an essential means to coat hardware workpieces and glass products. But at present, most coatings are difficult to adhere to some alloys (such as magnesium-aluminum alloy, zinc-aluminum alloy), stainless steel and glass products. In order to improve their adhesion, in the traditional coating method, an adhesion promoter must be added, but This method has problems of poor paint storage stability and poor paint film adhesion durability. It will not be very long; at the same time, it will also make the adhesion of the coating film better in the early stage and worse in the later stage. [0003] It can be see...
