Problems solved by technology

[0003] However, the commonly used matte cover printing silicone in the world generally has disadvantages such as poor matte effect, whitening after stretching, and poor wear resistance, and is not accepted by consumers. Some manufacturers also use hand oil instead of matte cover printing silicone. However, the shelf life of the hand oil is generally about one month, and the hand oil that exceeds one month will thicken sharply and the printing hand will be poor.

Abstract

The invention discloses lusterless cover face printing silica gel for silk-screen printing. The lusterless cover face printing silica gel is prepared from, by mass, 10-15 parts of lusterless cover face printing silica gel component A and 1-3 parts of lusterless cover face printing silica gel component B. The invention further discloses a preparation method of the lusterless cover face printing silica gel for silk-screen printing. The defect of the lusterless cover face gel on the market is overcome, the lusterless effect is outstanding, the gel is not likely to be whitened after being stretched, the storage life is long, and the printing hand feeling is good.

Description

technical field [0001] The invention relates to the field of silica gel screen printing, in particular to a matte cover printing silica gel for screen printing and a preparation method of the matte cover printing silica gel for screen printing. Background technique [0002] Screen printing silicone is different from the printing of a single material and effect of ink or glue. According to different surface effects, it can be divided into glossy rounded effect, bright right-angled effect, matte rounded effect, matte right-angled effect, flat right-angled effect. Among them, the matte effect is loved by consumers because of its smooth surface feel, non-sticky surface, and easy cleaning. [0003] However, the commonly used matte cover printing silicone in the world generally has disadvantages such as poor matte effect, whitening after stretching, and poor wear resistance, and is not accepted by consumers. Some manufacturers also use hand oil instead of matte cover printing sili...
