Abstract

The invention discloses high-brightness finishing printing silica gel for silk screen printing. The high-brightness finishing printing silica gel is prepared from the following raw materials in parts by mass: 10 to 15 parts of a high-brightness finishing printing silica gel component A and 1 to 3 parts of a high-brightness finishing printing silica gel component B. The invention further discloses a preparation method of the high-brightness finishing printing silica gel for the silk screen printing. According to the high-brightness finishing printing silica gel and the preparation method thereof, the defects of the general bright finishing gel are overcome; the high-brightness finishing gel with an outstanding brightness effect, high debubbling effect, urgent baking resistance, and zero hard spots and bubbles on a baked product is prepared; the finishing gel can be used for large-pattern printing finishing, to meet the requirement for the flowability, and also used for small-pattern finishing, to meet the requirement for avoiding smudging of a fillet.

Description

Technical field [0001] The invention relates to the field of silica gel screen printing, in particular to a high-gloss overlay printing silica gel for screen printing and a preparation method of the high-gloss overlay printing silica gel for screen printing. Background technique [0002] Screen printing silica gel is different from ink or glue with single material and single effect printing. It can be divided into bright round corner effect, bright right angle effect, matte round corner effect, matte right angle effect and flat right angle effect according to different surface effects. Among them, the bright rounded corner effect is loved by consumers because of its strong three-dimensional effect on the surface and a raindrop-like arc shape. [0003] However, the common gloss cover glue on the market contains a large amount of white carbon black, resulting in poor gloss effect, long defoaming time, intolerance to rapid baking, pitting and bubbles after baking, etc. unpleasant sig...
