Long-lasting wear-resisting aging-resisting UV (Ultraviolet) curing coating and preparation method thereof

Abstract

The invention discloses a long-lasting wear-resisting aging-resisting UV (Ultraviolet) curing coating which is characterized by being prepared from the following raw materials in parts by weight: 50-55 parts of urethane acrylate, 9-12 parts of cyclopentane, 7-9 parts of methoxy-polyethylene glycol monoacrylic ester, 3-4 parts of epoxidized soybean oil, 4-5 parts of photoinitiator 2959, 7-9 parts of resorcinol diglycidyl ether, 5-8 parts of ethylene glycol diethyl ether, 5-7 parts of ethyl acetate, 1-2 parts of titanate coupling agent TMC-TTS, 1-2 parts of grape essential oil, 5-7 parts of montmorillonoid, 2-3 parts of chromic oxide, 2-3 parts of antimonous oxide and 4-5 parts of additive. Due to addition of the natural anti-oxidation component grape essential oil, the aging-resistance of the coating is improved, and the coating is safe and non-toxic; due to addition of the antimonous oxide, a good flame retarding effect is achieved; due to addition of the additive, a good leveling property is achieved, a uniform coated layer can be formed, and the coating is fast in curing speed, high in hardness, wear-resisting, good in toughness, high in adhesion property, long-lasting in property and high in universality.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a durable wear-resistant and aging-resistant UV curing coating 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 materials are vario...

AI Technical Summary

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
