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 environment-friendly UV (Ultraviolet) curable coating with good closure. The curable coating is characterized by being prepared from the following raw materials in parts by weight: 50-55 parts of epoxy acrylate, 9-12 parts of cyclopentane, 5-9 parts of 1,6-bis(acryloyloxy)hexane, 3-5 parts of 2-hydroxyl-2-methyl-1-phenyl-1-acetone, 10-12 parts of acrylic acid-2-hydroxyl ethyl ester, 3-5 parts of xylene, 1-2 parts of polyphenylmethylsiloxane, 2-4 parts of tetrabutylammonium bromide, 2-3 parts of silane coupling agent KH560, 1-2 parts of IPBC (Iodopropynylbutylcarbamate), 5-7 parts of nano diatomite, 3-5 parts of nano ceramic powder and 4-5 parts of assistant. The nano diatomite is added, so that the coating has a good closure effect, and the coating has closure; the nano ceramic powder is added, so that the coating is uniformly dispersed, and the hardness of the coating is increased; the assistant is added, so that the leveling property is increased, and the coating is uniform, good in adhesive force, high in curing speed, corrosion resistant, wear resistant, simple in production process and suitable for being used as a closure primer.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an environment-friendly UV curing paint with good sealing performance 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 ...
