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 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 a UV (Ultra Violet) curable coating good in adhesion and high in curing speed. The UV curable coating is characterized by being prepared from the following raw materials in parts by weight: 50-55 parts of polyester acrylate, 9-11 parts of trimethylolpropane triacrylate, 7-9 parts of tripropylene glycol diacrylate, 4-5 parts of 2-hydroxyl-2-methyl-1-phenyl-1-acetone, 10-13 parts of ethoxylated trimethylolpropane triacrylate, 3-5 parts of xylene, 2-4 parts of methyl ethyl ketoxime, 1-2 parts of polydimethylsiloxane, 1-2 parts of freshwater mussel shell meal, 5-7 parts of nano zinc oxide, 4-6 parts of kaoline and 4-5 parts of auxiliaries. The UV curable coating is added with the nano zinc oxide, the coating is improved in dispersity and has excellent flame retardant efficiency and antibacterial effect; due to the added auxiliaries, the UV curable coating is good in leveling property, even in coating film and high in curing speed, and has excellent chemical resistance and low temperature resistance, and the coating film formed is high in adhesion to substrates difficult to stick, such as plastics.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a UV curable paint with good adhesion and fast curing speed 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 various, b...
