Abstract

The invention discloses a preparation technology for uvioresistant modified PET film coating liquid, which is characterized by comprising the following steps of: 1, preparing 15-50wt.% of conducting polymer resin, 15-50wt.% of silane coupling agent, 20-55wt.% of vinyl organic silicon resin, 0.1-2.0wt.% of glycerin, 0.05-1.0wt.% of antioxygen, 0.1-1wt.% of calcium stearate and 30-40wt.% of ultraviolet light absorber into slurry, wherein the ultraviolet light absorber is chlorinated benzotriazole type ultraviolet light absorber; 2, heating slurry in the step 1, wherein the heating temperature is 80-120 DEG C and the heating time is 10-30S. According to the preparation technology, the formula is improved, and the problem that in the prior art the PET film is colored that the visual effect is influenced is solved by adopting the method of mixing the ultraviolet light absorber with the PET functional layer master batch and then heating to melt.

Description

technical field [0001] The invention relates to a preparation process of an anti-ultraviolet modified PET film coating solution. 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. The conventional thickness is 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...
