Abstract

The invention discloses a cation light cured anti-corrosive coating. The coating is prepared from (by wt%) vinyl ether carbamate 10-80, epoxy resin 4-30, cation photoinitiator 0.5-5, assistant 0.1-3, and solvent in balance. By adopting reaction of polyisocyanate and multi-functional vinyl ether to synthesize vinyl ether carbamate with high reactivity, which is used as reactive diluent of epoxy resin curing, system viscosity can be reduced effectively, and light curing reaction speed can be fastened. The inventive coating has low viscosity and good adhesive force, and is especially suitable for endowing material surface with good anti-corrosive property under thin-coating condition.

Description

Technical field [0001] The invention belongs to the technical field of ultraviolet light curing coatings, and particularly relates to a cationic light curing anticorrosive coating. Background technique [0002] Ultraviolet curing coatings (UV coatings) use the energy of ultraviolet light to initiate polymerization and crosslinking reactions between low-molecular prepolymers or oligomers in the coating and monomer molecules as reactive diluents to obtain a hardened paint film A kind of paint that has the characteristics of fast curing, low energy consumption, no environmental pollution, and excellent coating performance. The cationic light curing system plays an important role in UV curing coatings. It has a small volume shrinkage rate during curing, strong adhesion to the substrate, the curing process is not blocked by oxygen, and the curing reaction is not easy to terminate. It is suitable for the light of the film. Curing and other advantages. Cationic light curing systems ge...
