Abstract

The invention provides a photocuring composition for metal corrosion resistance, application of the photocuring composition and a method of the metal surface corrosion prevention treatment. The photocuring composition comprises an oxetane compound, an oxirane structure-containing compound, an acrylic ester compound, a cation photoinitiator and a free radical photoinitiator. The photocuring composition for the metal surface corrosion prevention treatment provided by the invention has the advantages that the categories of main ingredients have more selectivity, the storage stability is relatively high and the composition has relatively good correspondence to an ultraviolet source and zero VOC (volatile organic compound) emission in the curing process. A cured coating has relatively excellentmanifestation in the aspects of adhesive force, hardness, cold and heat cycle resistance, temperature resistance, water boiling resistance, acid / alkali / salt resistance, gasoline resistance and the like, so that the photocuring composition has relatively strong market competitiveness and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to the technical field of metal anticorrosion, in particular to a photocurable composition for metal anticorrosion, its application and a method for metal surface corrosion protection treatment. Background technique [0002] In the prior art, metal anti-corrosion coatings mainly use solvent-based component systems, which have the problem of large VOC release during the later curing process, which is likely to cause serious environmental problems such as smog. With the improvement of people's awareness of environmental protection, the development and application of environmentally friendly light-curing coatings have received more and more attention. [0003] Mercury lamp ultraviolet light sources and UVLED lamps are mainly used for curing the existing environment-friendly light-curing coatings. The main components of metal anti-corrosion coatings suitable for the above curing conditions are photoinitiators, monomers and resins. Ex...
