Problems solved by technology

[0002] Glass frosting and frosting were originally operated manually and mechanically. The operation process is relatively primitive, and the frosting pattern obtained is not detailed enough. Some glass parts are frosted with wax protection or screen ink protection, and then the protected glass is placed in the frosting solution. The disadvantages of this process are complex operation, low efficiency and high cost
Chinese patent ZL96122275 introduces a "formulation and frosting method of frosting liquid for glass products". Affects the frosting effect

Abstract

An etching cream for silk screen printing on surface of glass is prepared through preparing etching powder from 10 raw materials including ammonium hydrogen fluoride, ammonium fluoride, starch, barium sulfate, etc. stirring in sealed state, proportionally mixing it with industrial hydrochloric acid, reaction, filtering to obtain etching liquid, mixing it with organic solvent, polyacrylic resin, polyose compound, barium salt and lipomatic compound, and stirring.

Description

1. Technical field [0001] The invention relates to a method for preparing a frosting material, in particular to a method for preparing a frosting paste for glass silk screen printing, in which various silk screen frosting glass products are obtained by coating the glass surface with a nylon screen. 2. Background technology [0002] Glass frosting and frosting were originally operated manually and mechanically. The operation process is relatively primitive, and the frosting pattern obtained is not detailed enough. Some glass parts are frosted with wax protection or screen ink protection, and then the protected glass is placed in the frosting solution. The disadvantages of this process are complicated operation, low efficiency and high cost. Chinese patent ZL96122275 introduces a "formulation and frosting method of frosting liquid for glass products". This patent uses the method of solution etching to obtain frosted glass. Affects the frosting effect. 3. Contents of the inv...
