Abstract

The invention discloses special alcohol-soluble silver ink high in cover performance and easy to scrape for PET (polyethylene terephthalate) plastics. The alcohol-soluble silver ink is prepared from components in percentage by mass as follows: 20%-30% of aluminium based silver paste, 25%-35% of an acrylic acid resin liquid, 5%-10% of avinyl chloride-vinyl acetate copolymer liquid, 10%-15% of kaolin, 10%-15% of ethyl ester and 1%-3% of isopropanol. The silver ink prepared from the acrylic acid resin liquid and thevinyl chloride-vinyl acetate copolymer resin liquid as binders is applicable to high-speed printing on the PET plastics, has high cover performance and proper adhesiveness, cannot fall off automatically, has certain adhesiveness but does not have tight adhesion, is free of benzene, ketone and toxin and is safe.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an alcohol-soluble high-coverage easy-scratching silver ink specially used for PET plastics. Background technique [0002] Polyethylene terephthalate, chemical formula COC 6 H 4 COOCH 2 CH 2 O, (English: Polyethyleneterephthalate, referred to as PET), by dimethyl terephthalate and ethylene glycol transesterification or terephthalic acid and ethylene glycol esterification to synthesize bishydroxyethyl terephthalate, and then It is obtained by polycondensation reaction. Aluminum-based silver paste is a pigment made of aluminum powder through a special surface treatment process and a corresponding solvent. It can reflect visible light and is silver-white, making it have good decorative performance and covering performance. However, the performance of the easy-to-scratch silver ink in the prior art is generally not stable enough, the scraping is not convenient and thorough enough, ...
