Abstract

The invention belongs to the application field of high-performance coating technology, and specifically relates to a high-hardness wear-resistant light-cured coating composition based on a multifunctional epoxy acrylate resin and a preparation method thereof; the composition consists of the following components in mass percentage Composition: multifunctional epoxy acrylate resin 30%‑50%, difunctional polyurethane acrylate resin 10%‑25%, multifunctional acrylate monomer 5%‑10%, difunctional acrylate monomer 20% %-30%, monofunctional acrylate monomer 10%-15%, photoinitiator 1%-3%; the present invention adopts epoxy acrylate resin containing acrylate double bond side chain as base resin, adding toughening The prepared photocurable coating composition has good adhesion and wear resistance, and the process is simple and controllable, and the price is low; it solves the problems of low hardness and poor wear resistance of general photocurable coatings.

Description

Technical field [0001] The present invention belongs to the field of high performance coatings applications technology, and particularly relates to a method for preparing a coating composition based on high hardness and wear resistance multifunctional epoxy acrylate photocuring resin. Background technique [0002] Coatings are cured by UV light photoinitiator decomposed to generate active species, with an active species to initiate polymerization, leaving a coating of a crosslinked cured coating. Epoxy acrylate resin coating material is one commonly used in a photocurable film-forming resin having a high curing rate, a cured film of high hardness, excellent adhesion to most substrates and so on. [0003] With the expansion of applications of light-curable coatings, optical performance requirements of increasing the cured coating. For example, imitation applied to glass or plastic substrate on the phone large screen display, which requires a coating having a high surface hardness....
