Abstract

The invention discloses modified (methyl) acrylate resin. The resin contains a (methyl) acrylate chain link, an unsaturated double bond and carboxylic group, an unsaturated double bond and epoxy group and an organic silicon group containing double bonds. The modified (methyl) acrylate resin can be solidified through various methods, has the characteristics of high hardness, high toughness, no adhesion, strong adhering force, good wear resistance and the like, and can be applied to fields such as coating, ink and adhesive. The invention further relates to a preparation method of the material.

Description

technical field [0001] The invention belongs to the technical field of organic polymer synthesis, and in particular relates to a multi-curable silicone-modified (meth)acrylate resin and a preparation method thereof. The resin can be applied to heat, ultraviolet light, moisture, and air-cured Coatings, adhesives, inks and other fields. Background technique [0002] In the prior art, various (meth)acrylate heat-curable and UV-curable resins have been proposed. The cured resin has fast light curing, high hardness of the coating film, good adhesion, good gloss, and chemical resistance. Corrosion and other advantages. [0003] (Meth)acrylate resins cured in two or more ways can generally achieve ideal results, but there is a problem of easy adhesion after one curing, and increasing the molecular weight will increase the viscosity and bring inconvenience to construction. An increase in the degree of crosslinking reduces the toughness. Adding a release layer can solve the above ...
