Abstract

The invention discloses a UV (Ultraviolet) cured primer having a flame-retarding effect. The UV cured primer is characterized by being prepared from the following raw materials in parts by weight: 50-55 parts of acrylic resin, 8-11 parts of N-acryloylmorpholine, 7-10 parts of 2-hydroxyethyl acrylate, 4-6 parts of 1-hydroxycyclohexyl phenyl ketone, 11-13 parts of glycol ether, 9-10 parts of allyl glycidyl ether, 3-5 parts of butanone, 1-2 parts of benzyltrimethylammonium tribromide, 1-2 parts of polydimethylsiloxane, 5-7 parts of brown fused alumina powder, 3-4 parts of aluminum hydroxide and 4-5 parts of aid. The coating is added with the aluminum hydroxide, so that a good flame-retarding effect is achieved; the aid is added, so that high levelling property, uniform coating, good coating of devices, excellent airtightness and high rubbing property are realized. The prepared coating has excellent water resistance, hot water resistance, drug resistance, bonding property and toughness, and is suitable to be taken as a primer.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a UV curable primer with a flame-retardant effect 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, but there...
