Problems solved by technology

[0002] The electrophoretic coatings currently prepared are generally epoxy resin and epoxy-modified acrylic acid. After the above-mentioned electrophoretic coatings are coated on the surface of metal workpieces, their water resistance, solvent resistance, salt spray resistance, light transmission and transparency are relatively low. Can be applied to metal surface coatings with low requirements

Embodiment 1

[0052] see figure 1 , 2 38 parts of isopropanol were put into a reaction kettle heated by heat conduction oil and the temperature was raised to 105 degrees, and then the mixed monomer 53 was added dropwise at a constant speed, and the dropping time was 6 hours. After the dropwise addition, keep warm for 2 hours, add 12 parts of isopropanol and initiator at a constant speed for one hour, cool to 45 degrees after the dropwise addition and keep warm for 1.5 hours, put in 27 parts of blocked isocyanate and mix for 1 hour, add 3.5 parts of refined lactic acid part, 1.2 parts of (bismuth) catalyst, and 43 parts of deionized water were mixed for one hour to obtain AC2008 novel acrylic acid / polyurethane transparent cathodic electrophoretic coating.

Abstract

The invention relates to an acroleic acid / polyurethane transparent anode electrophoresis coating and its preparation method, comprising the following raw materials (by weight ratio): cationic acrylic polymer 52-85, closed isocyanate cross linking agent 14.5-23.5, non-ionic or / and cationic surface active agent 4.6-8, catalyst 0.6-1.1, chain-transferring agent 0.5-0.8, deionized water 26-51. The cationic acrylic polymer comprises the following raw materials (by weight portions): isobutyl methacrylate 35-55, methyl acrylic ester 23-43, methyl methacrylic hydroxyl propyl ester 15-26, dimethyl amido propyl ester methacrylamide 13.5-23, 2-ethylhexyl methacrylate 13-28, azo-diisobutyronitrile 0.5-1.2, and dimethyl carbinol 35-89.

Description

technical field [0001] The invention relates to a metal surface decorative coating and a preparation method thereof, in particular to an acrylic / polyurethane transparent cathodic electrophoretic coating and a preparation method thereof. Background technique [0002] The electrophoretic coatings prepared at present are generally in the majority of epoxy resin and epoxy-modified acrylic acid. After the above-mentioned electrophoretic coatings are coated on the surface of metal workpieces, their water resistance, solvent resistance, salt spray resistance, light transmission and transparency are relatively low. It can be applied to metal surface coating with low requirements. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of acrylic / polyurethane transparent cathodic electrophoretic paint with high performance of water resistance, solvent resistance, salt spray resistance, light transmission and t...
