Abstract

The invention provides an acrylic ester compound and a preparation method and application thereof. The chemical structural formula of the acrylic ester compound is as follows (please see the specifications for the formula). The acrylic ester compound provided by the invention has the characteristic of double bonds, caprolactam and ester compounds, can be subjected to chemical reactions such as ring opening, polymerization, addition and hydrolysis, can be applied to all fields, and is particularly well applied to photocuring coatings.

Description

technical field [0001] The disclosure belongs to the technical field of acrylate synthesis and photocuring coating, and relates to an acrylate compound, a preparation method and an application. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Acrylate is an important polymer monomer and basic organic chemical raw material, widely used in coatings, papermaking, petrochemicals, chemical fiber coatings, adhesives, cosmetics and other fields. Polymers made from acrylates have excellent properties such as weather resistance, UV resistance, water resistance, and heat resistance. [0004] At present, there are mainly two methods for the synthesis of acrylates: direct esterification and transesterification. Because the direct esterification reaction is difficult to control and the yield is low, it is difficult to implement the direct esterification metho...
