Problems solved by technology

[0002] Resin is very common in daily life and production. It has excellent performance and is widely used. Acrylic resin is a very mature resin, such as for adhesion on substrates, or floors, etc., but conventional Acrylic resin usually has low adhesion and low alcohol resistance after forming a film on a metal substrate. In order to improve the characteristics of these two aspects, some manufacturers have adjusted and changed the synthesis or components, but the effect is still not good.

Abstract

The invention proposes novel resin, which is prepared from epoxy resin and an acrylic resin prepolymer through copolymerization according to the ratio of (55-65):100, wherein the acrylic resin prepolymer comprises the following components: 55-65wt% of methyl methacrylate, 5-10wt% of butyl methacrylate, 10-20wt% of ethyl acrylate, 5-10wt% of butyl acrylate, 8-10wt% of acrylic acid and 2-3wt% of benzoyl peroxide. The adhesive force of the novel resin on a substrate after a paint film is formed is improved, and can be up to over two grades, and the alcohol resistance is higher. The invention also proposes a preparation method of the novel resin. The method is simple and feasible, and applicable to popularization.

Description

technical field [0001] The invention relates to the field of synthetic resins, in particular to a resin, and also relates to a method for preparing the resin. Background technique [0002] Resin is very common in daily life and production. It has excellent performance and is widely used. Acrylic resin is a very mature resin, such as for adhesion on substrates, or floors, etc., but conventional Acrylic resin usually has low adhesion and low alcohol resistance after forming a film on a metal substrate. In order to improve these two characteristics, some manufacturers have adjusted and changed the synthesis or components, but the effect is still not good. Contents of the invention [0003] One of the objectives of the present invention is to propose a resin, which is mainly used to improve the adhesion and alcohol resistance of acrylic resin on the substrate under the premise of maintaining low cost. [0004] Another object of the present invention is to propose a resin prep...
