Abstract

The invention discloses a dual-modified and dual-cured epoxy acrylate coating material. The dual-modified and dual-cured epoxy acrylate coating material contains the following raw materials in parts by weight: 40-80 parts of polyethylene glycol modified epoxy acrylate resin (I), 20-60 parts of polyurethane modified epoxy acrylate resin (II), 0.01-0.05 part of ultraviolet initiator, 0.01-0.05 part of heat-curing initiator, 0.005-0.01 part of leveling agent and 0.005-0.01 part of defoamer. According to the dual-modified and dual-cured epoxy acrylate coating material, the polyethylene glycol modified epoxy acrylate resin (I) and the polyurethane modified epoxy acrylate resin (II) are mixed thoroughly according to an optimized formula, so that the viscosity of ultraviolet-curing epoxy acrylate is lowered, and the flexibility of a coating film is improved; the modified mixed resin has the advantages of low heat-curing temperature and high ultraviolet-curing speed, and can be applicable to the ultraviolet coating material curing construction of irregular substrates.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a double-modified, double-cured epoxy acrylate paint and a preparation method thereof. Background technique [0002] With the development of society and the progress of science and technology, more and more attention has been paid to environmental protection. Light-curing coatings are a kind of environmental protection and energy-saving coatings developed in the 1960s, which have been widely used and become commercialized coating products. Compared with other types of coatings, light-curing coatings have the advantages of fast curing speed, low curing temperature, energy saving and environmental protection, but simple light curing also has disadvantages, such as: the cured object must be flat, the curing depth It will also be limited, and it is difficult to achieve deep curing for the curing of colored paint. Therefore, in order to overcome the defects of light curing, dual curi...
