Silk-screening printing ink with high flexibility and high brightness

Abstract

The invention relates to printing ink, in particular to silk-screening printing ink with high flexibility and high brightness. The silk-screening printing ink with high flexibility and high brightness is characterized by comprising the following components in percentage by weight: 44 to 48 percent of bifunctional polyurethane resin, 16 to 20 percent of tetra-functional polyester resin, 9 to 13 percent of amine modified acrylic resin, 11 to 15 percent of acrylic ester monomer, 1 to 4 percent of fluorocarbon surface modifier, 1 to 5 percent of macroinitiator BP, 1 to 3 percent of organic silicon defoaming agent, 1 to 4 percent of organic silicon polyether modified flatting agent and 1 to 4 percent of bentonite. The printing ink has extremely high flexibility; and a product is difficult to crack after the printing ink is printed on the product. The printing ink has excellent weather resistance, is difficult to yellow and has high brightness after the printing ink is dried to form a film.The printing ink - does not produce byproducts after curing reaction and has low mobility and volatility, so that the printing ink has high environment friendliness, and the odor residue of volatile organic compounds (Vocs) completely meets the national standard requirement.

Description

technical field [0001] The invention relates to an ink, in particular to a screen printing ink with high flexibility and high brightness. Background technique [0002] Some of the existing UV inks used for screen printing have relatively poor flexibility, resulting in products that are not resistant to folding and easy to burst; some have relatively poor transparency, resulting in a dull overall color of the product, lack of visual impact and counter effect; Some inks are not environmentally friendly enough, the product VOCs odor residue does not meet the national standards, and the ink lines are relatively simple, mostly irregular cracks or sand spots. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a technical solution of screen printing ink with high flexibility and high brightness. [0004] The screen printing ink with high flexibility and high brightness is characterized in that: ...
