Problems solved by technology

[0003] The current UV curing materials are various, but there are still some problems to varying degrees. The existing UV curing coatings have a large shrinkage rate after photocuring and produce shrinkage stress, resulting in brittleness of the coating film, adhesion and impact resistance. Poor, poor flexibility and low hardness of the coating film, no corrosion resistance, easy yellowing and aging, etc. These series of problems need to be continuously improved for different purposes, reduce production costs, and expand uses

Abstract

The invention discloses an ultraviolet curing coating for plastifying and reinforcing a metal material. The ultraviolet curing coating for plastifying and reinforcing the metal material is characterized by being prepared from the following raw materials in parts by weight: 45-50 parts of urethane acrylate, 8-10 parts of polyethylene glycol diacrylate, 6-9 parts of methoxy polyethylene glycol methacrylate, 4-5 parts of photoinitator 1173, 11-13 parts of trimethylolpropane triacrylate, 6-8 parts of tricarboxymethyl propane triglycidyl ether, 1-2 parts of yttrium oxide, 2-3 parts of dicyclopentadiene, 5-7 parts of amorphous silicon dioxide and 4-5 parts of auxiliary agent. According to the invention, plastifying and reinforcing substances such as yttrium oxide and dicyclopentadiene are added, so that the obtained ultraviolet curing coating has strong caking property, abrasion resistance, acid-base resistance and corrosion resistance; the auxiliary agent is added, so that levelling property is good, a film is uniform, the curing speed is high and the ultraviolet curing coating for plastifying and reinforcing the metal material is applicable to a primer of the metal material.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an ultraviolet curing coating for plasticizing and reinforcing metal materials and a preparation method thereof. Background technique [0002] UV curing coatings have become a relatively mature technology, especially with the improvement of people's awareness of environmental protection, production and researchers pay more attention to the development and application of UV curing coatings. UV curing coating is a kind of green and environment-friendly coating, which fully complies with the "4E" principle. Generally, the energy consumption of UV curing is 1 / 5 of that of thermal curing, and UV curing coating contains less volatile components and less pollution. It is most attractive to researchers. And the developer's advantage is that UV curing coatings can reduce raw material consumption, which is beneficial to reduce economic costs. [0003] The current UV curing mat...
