Abstract

The invention discloses an anti-sublimation silica gel printing coating. The anti-sublimation silica gel printing coating is composed of a component A and a component B according to the mass ratio of 10: 1.5-10: 0.6, wherein the component A is prepared from the following components in parts by mass: 100 parts of vinyl polysiloxane, 0.05 to 0.1 part of deionized water, 5 to 30 parts of tetraethoxysilane, 10 to 15 parts of n-heptane, 5 to 10 parts of white carbon black and 0.9 to 1.5 parts of platinum catalyst; the component B is prepared from the following components in parts by weight: 100 parts of hydrogen-containing silicone oil and 5-10 parts of an inhibitor; the invention further discloses a preparation method of the anti-sublimation silica gel printing coating. According to the silica gel printing paste and the preparation method thereof, by adopting an in-situ dispersed distribution nano filling technology, anti-sublimation nano-particles are introduced into the silica gel printing paste, the particles hardly influence the original performance of the silica gel paste, and meanwhile, the approximate transparent and anti-sublimation effects can be achieved.

Description

Technical field [0001] The present invention relates to the technical field of wire mesh silica printing, and more particularly to anti-lifting silica gel printing coatings and preparation methods thereof. Background technique [0002] In the field of textile printing, the dyes or pigments used on Dark T-shirts, swimsuits, children's wear, bags, tents, etc. are prone to sublimation and migrated to glue or silica gel printing surface, which makes printed to be contaminated and lost the original color. It has caused the printing product to be unqualified and even scrapped. Since the process often occurs after the production of product production, it is difficult to repair and make up. Once the above situation, the company's loss is large. [0003] The sublimation of dyes or pigments is mainly related to molecular movement at high temperatures. When the dye or pigment is poor, it occurs at high temperatures, when printed glue or silica gel, if there is a gap between the printed laye...
