Abstract

The invention discloses a magnalium photocureable coating which is characterized by being prepared by adding 1-3% of adhesion promoter and 1-3% of mixed trigger such as 1173 and TPO and the like in the traditional photocureable coating and overcomes the shortage that the traditional photocureable coating is not suitable to being coated onto magnalium. The magnalium photocureable coating disclosed by the invention can be coated on magnalium and has the excellent properties of very strong adhesion, high abrasion resistance, salt mist resistance and thermal shock resistance, and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a magnesium-aluminum alloy light-curing coating. Background technique [0002] Existing light-curing coatings are not suitable for magnesium-aluminum alloys. If they are applied reluctantly, they will have disadvantages such as poor adhesion and easy peeling off. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing light-curing coatings are not suitable for magnesium-aluminum alloys, and to provide a magnesium-aluminum alloy with excellent properties such as firm bonding, no falling off, wear resistance, salt spray resistance, and thermal shock resistance. paint. [0004] The technical solution of the present invention is: add adhesion promoter, 1173 and TPO mixed initiators to the existing light-curing coating, and use high-boiling-point environmental protection solvent as the solvent, and its specific ratio is as fo...
