Abstract

Thermoplastic colorless and transparent glass protection ink is prepared from, by weight, 30-60 parts of thermoplastic acrylic resin, 30-65 parts of high boiling point solvent, 0.5-3 parts of antifoaming agent, 0.2-1.5 parts of flatting agent and 0.2-1.5 parts of coupling agent .The ink is formed by mixing and stirring the thermoplastic acrylic resin, the high boiling point solvent, the antifoaming agent, the flatting agent and the coupling agent .The ink is completely colorless and transparent, capable of being dried fast, high in hardness and good in CNC resisting technology, adapts to printing of silk screens of 200-350 mesh, and is mainly applied to the fields of protection of glass needing high light transmittance and the like.

Description

technical field [0001] The invention belongs to the field of glass protective inks, in particular to a thermoplastic colorless transparent glass protective ink and a preparation method thereof. Background technique [0002] As a high-strength, scratch-resistant glass, glass is widely used in high-end smartphones, tablet computers, flat-screen TVs, and industrial and commercial touch screens. In the field of glass processing, the glass surface will be scratched during special processing such as cutting, edging, and polishing, resulting in a defective product rate as high as 99%. At the same time, the damaged glass will also increase the subsequent polishing and flat grinding process, thereby increasing the production cost. [0003] In order to solve the above technical problems, a variety of protective inks have been developed on the market. These protective inks are mainly printed on the surface of the glass by silk screen printing to form a protective film, which is remove...
