Problems solved by technology

Organic fluorine monomers have anti-fouling properties, but are easy to volatilize and have poor compatibility with coating components, making it difficult to meet the high performance requirements of coatings
In the prior art, the organic fluorine and silicone components contained in the coating are mostly blended in a physical way, which is prone to phase separation, which limits the application range of the material

Abstract

The invention discloses a cationic photo-cured fluorine-containing organosilicon composite coating and a preparation method thereof. The composite coating comprises cationic photo-cured fluorine-containing organosilicon, an epoxy resin, a cationic photoinitiator and an auxiliary agent. The coating of the invention has excellent flexibility and impact resistance, and strong water resistance and dirt resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a cationic light-curing fluorine-containing organic silicon composite coating and a preparation method thereof. Background technique [0002] UV curing technology is widely used in the fields of coatings, inks, adhesives, photoresists, and printing materials. It has the characteristics of fast curing, low energy consumption, no environmental pollution, and excellent coating performance. Among them, cationic light curing, as a new curing technology, has the advantages of no oxygen inhibition, small curing volume shrinkage, strong adhesion to metal plastics, and difficult termination of the reaction. Organic fluorine monomers have anti-fouling properties, but are easy to volatilize and have poor compatibility with coating components, making it difficult to meet the high performance requirements of coatings. In the prior art, the organic fluorine and silicone components contained in the pai...
