Problems solved by technology

[0003] Traditional coatings need to be cured at high temperatures, consuming a lot of energy
Although general UV-curable coatings have the characteristics of high gloss and high hardness, they also have the following defects: easy to be stained by fingerprints, imprints of oil-based pens are not easy to remove, and poor pollution resistance
This limits its application to some extent
Due to the principle of similar compatibility, polymer materials have a good affinity for oily materials, and it is difficult to meet this requirement with conventional polymer materials. Therefore, other domestic manufacturers have not made breakthroughs in this performance, and this industry has been used by South Korea. Monopolized by KCC Group and Korea Chaoguang Paint Co., Ltd.

Abstract

The invention discloses an ultraviolet-curable pollution-resistant coating. The ultraviolet-curable pollution-resistant coating is prepared from the following components in parts by weight: 60-75 parts of modified epoxy acrylate, 58-68 parts of epoxy acrylate, 20-25 parts of urethane acrylate, 30-35 parts of polyester modified acrylate, 12-18 parts of pentaerythritol pentaacrylate, 13-23 parts of tripropylene glycol diacrylate, 7-8 parts of pollution-resistant photocuring auxiliary, 1-8 parts of photoinitiator, 32-39 parts of diluent and 2-4 parts of a flatting agent. The ultraviolet-curable pollution-resistant coating is an ultraviolet-curable coating which can be cured instantaneously under ultraviolet irradiation at a room temperature; besides, the ultraviolet-curable pollution-resistant coating has excellent pollution resistance and iodine resistance, and is capable of achieving the purposes of energy conservation, environmental protection and fast curing.

Description

technical field [0001] The invention relates to an ultraviolet light curing stain-resistant coating, which belongs to the field of coatings. Background technique [0002] UV-curable coatings are mainly composed of oligomers, monomers, photoinitiators and additives. The main reaction process of UV curing is that the photoinitiator is decomposed by radiation to generate active free radicals to initiate the polymerization and crosslinking of monomers / oligomers. Over the past few years, UV-curable coatings have grown rapidly in fiber optic coatings, CD coatings / DVD adhesives, credit cards, wood, beverage cans, food packaging, magazine covers, medical devices, and the automotive industry . UV-curable coatings have huge market potential, and their proportion in the entire coating products is increasing year by year. With the increasing application range of UV curing, there are also important breakthroughs in technology. [0003] Traditional coatings need to be cured at high te...
