Visible light cured metal paint

Abstract

The present invention relates to metal paint, and is especially visible light cured paint for the surface protection and decoration of various kinds of metal. The visible light cured paint for metal consists of prepolymer of unsaturated olefin radical 0-20 wt%, monomer of unsaturated olefin radical 20-80 wt%, light initiator 1-10 wt%, initiator assistant 0.5-30 wt%, assistant 0-10 wt%, stuffing or pigment 0-40 wt% and solvent 0-30 wt%. The visible light cured paint may be used widely in surface coating of iron and steel, aluminum, copper and other metals and alloys.

Description

technical field [0001] The invention belongs to the field of coatings for metals, in particular to visible light-curable metal coatings used for the protection and decoration of various metal surfaces. Background technique [0002] At present, the coatings used in metal surface treatment mainly include alkyd paint, acrylic baking paint, electrophoretic paint and powder coating. Alkyd paint has high VOC content and poor physical and chemical properties of the paint film; acrylic baking paint, electrophoretic paint and powder coating all have disadvantages such as high equipment investment cost, long drying time, and high energy consumption. [0003] UV-curable coating is a low-odor, low-toxicity, low-VOC and fast-curing coating that has been successfully applied to the surface coating of wood, paper, plastic and metal. However, UV curing technology still has its disadvantages: first, UV curing requires special equipment, and some objects with irregula...
