Abstract

The present invention relates to liquid polymer, and is especially one kind of environment friendly black paint specially for shading PVC film and its preparation process and use. The environment friendly black paint consists of dye 8-12 wt%, butyl acrylate 15-25 wt%, chlorosulfonated polypropylene 5-10 wt%, Teflon 15- 25 wt%, polystyrene 4-6 wt%, assistant 0.05-0.15 wt%, and organic solvent for the rest. Its preparation process includes the following steps: 1. adding butyl acrylate, chlorosulfonated polypropylene, Teflon and polystyrene into the organic solvent, and dissolving butyl acrylate completely; 2. adding dye and stirring; 3. adding assistant to form thick slurry; and 4. grinding and filtering. The environment friendly black paint is coated onto PVC film to form shading film.

Description

technical field [0001] The invention relates to a high-molecular liquid polymer, which is an environment-friendly polymer, in particular to an environment-friendly black paint specially used for shading PVC films and its preparation method and application. Background technique [0002] At present, in the international and domestic markets, there are mainly two ways to cover the light transmission of PVC film. One is to heat-roll a layer of black PVC film on the back of the white PVC film, and use the black PVC film to play the role of shading; the other One is to coat black glue on the back of the white PVC film, and use black glue to play the role of shading. Both methods have shortcomings. The disadvantage of the former is that the black and white PVC film will separate after long-term use, which will affect the performance of use. The latter will easily cause black glue to remain on the surface of its use. Contents of the invention [0003] The object of the present in...
