Problems solved by technology

[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. Spray a layer of paint directly on the back of the film or curtain. Under the strong sunlight, it will emit a pungent smell and contain certain toxic gas emissions. This problem needs to be solved urgently

Embodiment Construction

[0014] The present invention will be described in detail below in combination with specific embodiments.

[0015] A polymer opaque film, such as figure 1 As shown, it includes a PET layer 1, one side of the PET layer 1 is provided with a metal electroplating layer 2, and one side of the metal electroplating layer 2 is provided with a black polymer material polyvinyl chloride layer 3 Molecular formula [-CH2--CHCl-] n, the black polymer material polyvinyl chloride layer 3 molecular formula [—CH2——CHCl—]n is provided with a polymer material polyvinyl chloride color layer 4 molecular formula [—CH2——CHCl—]n.

[0016] The first step is material pretreatment and machine preheating;

[0017] The second step is to electroplate the PET metal layer.

[0018] The third step is to combine the electroplated metal PET layer with two layers of polymer material polyvinyl chloride molecular formula [-CH2--CHCl-]n, and one side of the metal plating layer is provided with a black polymer materi...

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...
