Problems solved by technology

[0004] Before the 1960s, the production of vinyl chloride monomer was basically based on calcium carbide acetylene, because the production of calcium carbide required a large amount of electric energy and coke, and the cost was high
[0006] At present, although polyvinyl chloride is the most commonly used plastic, the effect of its surface coating is not ideal, and it is easy to cause problems such as peeling off and virtual plating.
This greatly restricts the use of polyvinyl chloride

Abstract

The invention discloses an environment-friendly film-coating method of polyvinyl chloride. The environment-friendly film-coating method of the polyvinyl chloride comprises the following steps: performing acid washing, alkali washing and water washing on the surface of a polyvinyl chloride, performing alcohol liquid ultrasonic reaction, coating the surface of the polyvinyl chloride with cyclohexanone to perform corrosion, cleaning completely without water, coating with a metal oxide film, performing electrolytic reaction and constant-pressure reaction by taking a methanol liquid film as electrolyte, and relieving pressure slowly to obtain the polyvinyl chloride material of a compact film. The method provided by the invention is simple, rapid and high in environmental friendliness, and the existing environmental protection requirement is met.

Description

technical field [0001] The invention belongs to the field of plastic coating, and particularly relates to an environmental protection coating method for polyvinyl chloride. Background technique [0002] Polyvinyl chloride was once the largest general-purpose plastic in the world and has a wide range of applications. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc. [0003] Polyvinyl chloride was industrialized in the early 1930s. Since the 1930s, for a long time, the production of polyvinyl chloride has been the first in the world's plastic consumption. In the late 1960s, polyethylene replaced PVC. Although polyvinyl chloride plastic is now in second place, its output still accounts for more than a quarter of the total plastic output. [0004] Before the 1960s, the production of monomeric vinyl ...
