Light-tight polymeric membrane and production method thereof

Abstract

The invention provides a light-tight polymeric membrane. The light-tight polymeric membrane comprises a PET (polyethylene terephthalate) layer, wherein a metal plating layer is arranged on one side of the PET layer, a black high polymer material polyvinyl chloride layer with the molecular formula of [-CH2--CHCl-]n is arranged on one side of the metal plating layer, and a high polymer material polyvinyl chloride color layer with the molecular formula of [-CH2--CHCl-]n is arranged on one side of the black high polymer material polyvinyl chloride layer with the molecular formula of [-CH2--CHCl-]n. The light-tight polymeric membrane is reasonable in design and reliable in structure, potential quality problems are avoided, the membrane is totally light-tight, ultraviolet rays prevented, entering heat is reduced, sunlight is reflected, and the membrane has the characteristics of no toxicity, no odor, high temperature resistance, aging resistance, long service life and the like, has different colors and patterns for matching and can be used for spatial decoration in a room.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to a polymer opaque film and a manufacturing method thereof. Background technique [0002] The current films are widely used, including indoors and outdoors, inside and outside the car, on curtains or shower curtains, but most of the films on the market are usually light-transmitting, and cannot be completely light-proof, and there is no Light-transmitting films or curtains are easy to make. A layer of paint is directly sprayed on the back of the film or curtain. Under strong sunlight, it will emit a pungent smell and contain certain toxic gas emissions. This problem needs to be solved urgently. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a polymer opaque film with reasonable structure and convenient use and its manufacturing method, which solves the above-mentioned problems. [0004] The tec...
