Abstract

The invention discloses a manufacturing method of a silicon-double-coated PET release film. The method comprises the following steps: (1) conductive polymer resin, hydrogen-containing silicone oil, vinyl organosilicon resin, a composite stabilizer, a lubricant, 5-30 parts by weight of an enhancing agent, 0.02-0.05 parts by weight of a pigment, and 5-8 parts by weight of a toughening agent are prepared into slurry; and the slurry is used for uniformly coating the upper and lower surfaces of a substrate film once; (2) the coated substrate film is subjected to thermal curing and light curing, wherein the thermal curing temperature is 80-120 DEG C, the thermal curing time is 10-30s, the light curing intensity is 80-120W / cm, the light curing dose is 100-400J / cm<2>, and the irradiation time is 5-20s. According to the invention, the formula is improved, such that rigidity and strength are effectively improved. The toughening agent specially developed by the company is adopted, such that a toughness problem is effectively solved. The imported enhancing agent is adopted, such that produce strength is improved.

Description

technical field [0001] The invention relates to a manufacturing process of a double-sided silicon-coated PET release film. Background technique [0002] The PET release film is based on PET film, and a layer of silicone oil is coated on the surface of the PET film to make the surface of the PET film slide up to reduce the surface tension of the PET film. To achieve the effect of release. [0003] PET release film is a material commonly used in thermal transfer printing. The substrate is PET, which is coated with silicone oil, so it is also called silicone oil film. Regular thickness ranges from 25um to 150um. There are hot and cold tearing and matte surface, after anti-static and anti-scratch treatment, the product has good adsorption and fit. [0004] PET release film has been widely used in packaging, printing, screen printing, pad printing, nameplate, membrane switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, lamination, electroni...
