Abstract

The invention discloses a thermal transfer printing silica gel which is characterized by comprising base silica gel, crosslinking agent, color paste and silica gel modifying assistant D in a mass ratio of 10:1:1:1, wherein the base silica gel is prepared by mixing 70-85 parts by mass of dimethyl ethenyl silicon oil, 15-30 parts by mass of white carbon black and 0.01-1 part by mass of assistant B; and the crosslinking agent is prepared by mixing 70-80 parts by mass of dimethyl siloxane hybrid ring DMC, 3-10 parts by mass of methyl hydrogen-containing silicon oil and 0.05-0.2 part by mass of assistant C. The invention also discloses a preparation method of the thermal transfer printing silica gel and application of the thermal transfer printing silica gel. The thermal transfer printing silica gel can be transferred to cotton fabric, Lycra, microfibers, nylon, waterproof nylon, nylon meshes, PU (polyurethane) and true leather. The silica gel thermal transfer printing product prepared by the silica gel has the advantages of super fastness to washing, high elasticity, super softness and the like, and is simple to operate.

Description

technical field [0001] The invention relates to the technical field of silicone and heat transfer printing, in particular to a heat transfer printing silica gel, a preparation method, and an application of the heat transfer printing silica gel. Background technique [0002] Organosilicon is a high molecular polymer with semi-inorganic and semi-organic structure. It is non-toxic and polluting to the environment, and it is physiologically inert. It adheres to and solidifies on the surface of the fiber, and has the functions of modifying, repairing, beautifying the appearance of the fiber and improving its function. It is an excellent eco-friendly textile finishing agent. With the development of science and technology and the growing demand of people, the research of silicone in coating and screen printing emerges in an endless stream, and gradually emerges. Part of the market that replaces ink and glue has also received more and more attention. [0003] Thermal transfer print...
