Electroplating finish and preparation method thereof

Abstract

The invention discloses an electroplating finish mainly comprising the following components by weight: 16.2% of nitrocotton, 15% of bismaleimide resin, 6.8% of ethyl ester, 30% of isobutyl ester, 14.5% of keto-aldehyde resin, 8.5% of 2-ethoxyethyl acetate, 3.5% of matt powder, 1.8% of sodium silicate, 3.2% of wax powder, and 0.5% of a polyether modified dimethyl siloxane solution. The preparation method of the electroplating finish includes the steps of: first mixing bismaleimide resin, ethyl ester, isobutyl ester and keto-aldehyde resin in proportion and stirring them uniformly so as to obtain a diluent; then adding the nitrocotton, 2-ethoxyethyl acetate, matt powder, sodium silicate, wax powder, polyether modified dimethyl siloxane solution and diluent in proportion into a dispenser for stirring well. The finish product of the invention has the advantages of good handle feel and adhesion, good surface gloss and rapid drying speed, as well as no influence on the inherent gloss of an electroplating piece, etc. Also the method for producing the electroplating finish has simple technology and low cost.

Description

technical field [0001] The invention relates to a chemical coating, in particular to an electroplating coating for plastic surfaces, and belongs to the technical field of chemical coatings. technical background [0002] my country's electroplating coating industry is developing rapidly, and the demand for electroplating coatings in the industry is also increasing.
