Digital printing transfer paper surface coating liquid

Abstract

The invention relates to digital printing transfer paper surface coating liquid which is composed of, by mass, 20-24 parts of methyl etherified urea-formaldehyde resin, 22-26 parts of methyltriacetoxysilane, 18-22 parts of polyvinyl chloride resin, 16-20 parts of silicon dioxide powder, 22-26 parts of polyurethane, 18-22 parts of inorganic nanometer zirconium oxide, 16-20 parts of talcum powder, 22-26 parts of polymethyl methacrylate, 16-20 parts of chlorinated polypropylene resin, 16-20 parts of ethyl carbamate resin, 22-26 parts of chlorothalonil, 18-22 parts of polytetrafluoroethylene micro powder, 16-20 parts of fluorescent powder, 22-26 parts of permethrin, 18-22 parts of sodium tripolyphosphate, 16-20 parts of phenothiazine, 22-26 parts of zircon powder, 18-22 parts of chloroplatinic acid and 1,000-2,000 parts of water. The texture of transfer printing patterns obtained after thermal dye sublimation transfer printing is conducted on the coating liquid is clear, saturate, high in colour fastness and durable without color fading; the coating liquid has good anti-mildew and anti-bacterium performance.

Description

technical field [0001] The invention relates to a surface coating liquid for digital printing transfer paper, which belongs to the technical field of digital printing. Background technique [0002] In recent years, in order to solve the problem that the surface decoration of glass, ceramics, metal and other products is too simple, people have begun to apply thermal transfer technology, and use the method of direct transfer to decorate the products of the above materials. However, due to the products of the above materials The surface is smooth and polar, and the adhesive layer of the general transfer film cannot be tightly combined with the surface of the above-mentioned products. Therefore, the graphics and texts are very easy to fall off after the transfer, and the decorative effect is not ideal. The traditional sublimation transfer printing refers to printing the sublimation transfer ink onto the paper by printing, and overlapping the printed paper with the fabric to heat...
