Application of organic silicon gel in transfer printing

Abstract

The invention discloses a method using organic silicon gel to perform transfer printing. Organic silicon gel can be divided into a gel agent using silicone as a base material and a gel agent using silastic as a base material. The organic silicon gel has various colors, such as no color, white, black, and the like, exists in shapes, such as a liquid state, a semi-solid state, a solid state, and the like, has better adhesive force and fastness, no toxicity and environmental protection, is bright, soft and elastic after being dried and solidified, and has water resistance, wear resistance, high and low temperature resistance, light resistance, ozone aging resistance, high air penetrability, electrical insulation and special surface performance and physiological inertia. At present, the organic silicon gel is widely applied to automobile fittings, space flight sealing articles, medical artificial organs, and the like. A paper pattern surface to be transferred and printed is coated with the organic silicon gel, and paper coated with patterns and silicon gel films is wetted by water, removed and stuck so as to perform transfer printing after the silicon gel is dried and forms films. The transfer printing procedure is simple, the process is environmental-friendly and the precision of transfer printing output images is high.

Description

technical field [0001] The invention relates to a transfer printing method, in particular to a method for transferring images and characters on paper through organic silica gel. technical background [0002] Organic silica gel can be divided into two types: silicone resin-based adhesives and silicone rubber-based adhesives. Silicone resin-based adhesives are composed of silicone resin, inorganic fillers and solvents. Silicone Rubber-based adhesives are composed of silicone rubber, crosslinking agents, catalysts, fillers and other additives. The basic structural unit of silicone products is composed of silicon-oxygen chain links, and the side chains are formed by silicon atoms. Linked to various other organic groups. [0003] Organic silica gel has colorless, white, black and other colors, exists in the form of liquid, semi-solid, solid, etc., has good adhesion and fastness, non-toxic, harmless, environmentally friendly, after drying, it is bright and soft , Elasticity, wat...
