Abstract

The invention discloses an ultraviolet curing coating capable of being used on surfaces of plastic and stone. The ultraviolet curing coating capable of being used on the surfaces of plastic and stone is characterized by being prepared from the following raw materials in parts by weight: 20-25 parts of bisphenol A epoxy acrylate, 30-35 parts of polyester acrylate, 10-12 parts of hydroxyethyl acrylate, 6-9 parts of hydroxyethyl methylacrylate, 3-5 parts of photoinitator 2959, 10-13 parts of neopentyl glycol dicarylate, 9-11 parts of cresyl glycidyl ether, 1-2 parts of sodium hexametaphosphate, 1-2 parts of methyl ethyl ketone, 3-5 parts of titanium dioxide, 1-2 parts of grape seed oil, 4-6 parts of barite powder and 4-5 parts of auxiliary agent. The ultraviolet curing coating capable of being used on the surfaces of the plastic and stone is added with a natural antioxidant ingredient of grape seed oil, the anti-aging property of the ultraviolet curing coating can be enhanced, and the ultraviolet curing coating is safe and non-toxic; an auxiliary agent is added, so that the ultraviolet curing coating is uniformly dispersed, the curing speed is high, a film can be rapidly formed, the surface hardness of the film is high, the glossiness is good, the hiding power is high, the film is uniform, and the ultraviolet curing coating has good adhesion property and can be rapidly adhered on the surfaces of plastic and stone.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an ultraviolet curing paint which can be used on the surface of plastic stones 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 mater...
