Screen printing ink and preparation method thereof

Abstract

The invention provides screen printing ink and a preparation method thereof. The screen printing ink is prepared from the following components in parts by weight: 30 to 42 parts of polyester resin, 32to 42 parts of modified polyester resin, 22 to 25 parts of vinyl chloride-vinyl acetate resin, 26 to 32 parts of acrylic resin, 28 to 32 parts of a Cytec acrylate active monomer, 40 to 45 parts of asolvent, 0.5 to 1.5 parts of a dispersant and 0.5 to 1.3 parts of a de-foaming agent. The screen printing ink provided by the invention has the advantages of more stable adhesive force and more excellent wear resistance and chemical resistance.

Description

technical field [0001] The invention relates to the field of screen printing inks, in particular to a screen printing ink and a preparation method thereof. Background technique [0002] At present, in the processing of the outer surface of mobile phones, car navigators, tablet computer shells, phone buttons and other products, a layer of UV paint (ultraviolet curing paint) is first sprayed on the surface of the parts, and then the traditional UV paint is used. Inks (UV curable inks) or traditional thermosetting inks are used for decoration or other processing on the UV lacquer layer. Although the traditional UV inks used can meet the requirements of high wear resistance, the traditional UV inks have unstable adhesion and poor wear resistance on some UV topcoats, and the chemical resistance cannot meet the requirements. Therefore, often It will cause the processing quality of the workpiece is not high, the quality of the finished product is not up to standard, there are many...

Problems solved by technology

Although the traditional UV inks used can meet the requirements of high wear resistance, the traditional UV inks have unstable adhesion and poor wear resistance on some UV topcoats, and the chemical resistance cannot meet the requirements. Therefore, often It will cause the processing quality of the workpiece is not high, the quality of the finished product is not up to standard, there are many defective products, and it is not durable
