Problems solved by technology

As a result, environmental damage is caused. Moreover, after spraying, it is necessary to wait for the volatile organic solvent to volatilize before it can be dried by light, which also affects the aging effect.
If the heating method is used to accelerate the volatilization of volatile organic solvents, resources will be wasted

Abstract

The invention relates to a spray painting UV primer, in particular to a spray painting UV primer without volatile organic compounds and a preparation method thereof. The spray painting UV primer without the volatile organic compounds comprises an active diluent, an oligomer, a photoinitiator and auxiliaries. The active diluent comprises at least one optical-active (methyl) acrylate functional group, the oligomer is selected from the acrylic acid resins compounds, the photoinitiator is selected from the cation photoinitiators, and the auxiliaries contain an antifoaming agent, an anti-settling agent, constitutional materials and an active amine. The spray painting UV primer does not contain the volatile organic compounds, thereby greatly reducing the environment pollution of the UV primer, and avoiding the influence on the primer performance because the volatilization of the organic compounds has influences on the viscosity of the primer during the spray painting. The spray painting UV primer can be dried by irradiation after the spray painting, and the testing result indicates that the drying time is about 5 to 10 seconds, and the drying speed is fast, thereby effectively saving the processing time.

Description

technical field [0001] The invention relates to a spraying UV primer, in particular to a spraying UV primer without volatile organic compounds and a preparation method thereof. Background technique [0002] The main components of polyurethane ultraviolet curing primer, that is, UV primer, include dissolving the solid components in the UV primer, adjusting the viscosity of the system reactive diluent, the oligomer as the basic skeleton in the UV primer, and the ability to transmit ultraviolet photons Energy, rapidly initiate cross-linking polymerization of monomers and oligomers, photoinitiator to promote the liquid-solid conversion process of the system and additives to improve the performance of the paint film. Among them, the reactive diluent in the UV primer generally does not contain volatile organic solvents, but contains non-volatile solvents that directly participate in the curing and film-forming process and have the ability to react, that is, reactive monomers. Howe...
