Bi-component modified polyester resin thermosetting ink

Abstract

The invention discloses bi-component modified polyester resin thermosetting ink which comprises BM 607 white and BM 690 high-dyne-value black. The BM 607 white is mixture comprising, in concentrationrange (percent), 20-50% of polyester resin, 2-10% of propylene glycol methyl ether acetate, 25-35% of isophorone, 40-50% of titanium dioxide and 2-5% of auxiliaries. The BM 690 high-dyne-value black is mixture comprising, in concentration range (percent), 20-50% of polyester resin, 2-10% of propylene glycol methyl ether acetate, 25-35% of isophorone, 20-30% of carbon black and 2-5% of auxiliaries.The ink is high in covering power, good in printability and applicable to printing of a glass cover plate, and a cured ink layer has excellent adherence, chemical resistance and boiling resistance, high surface tension and the like.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a two-component modified polyester resin thermosetting ink. Background technique [0002] The ink of the present invention is mainly used for printing of LEDs and touch panels, and silk screen printing technology runs through the entire glass industry and plays a pivotal role in it. So, as one of the important fields in the silk screen printing industry, what role does glass screen printing play in the screen printing industry? Glass screen printing technology introduction Glass screen printing is to use screen printing plates and glass glazes to perform decorative printing on glass products. Glass glaze is also called glass ink and glass printing material. It is a paste printing material made by mixing and stirring coloring material and linking material. The coloring material is composed of inorganic pigments and fluxes with high and low melting points. The printed glass products...

Problems solved by technology

[0004] At present, it is known that the shielding properties, dyne value, water drop angle, and printability of existing products are difficult to meet the requirements of the latest technology of customers (such as the influence of dyne value and water drop angle on the film laminating process of touch panels, and the water drop angle is less than 90 If the degree and dyne value is lower than 40, the hydrophilicity and leveling of the glue during the lamination process of the touch panel will be poor, and the defect rate of the inverted product will be too high
