Problems solved by technology

[0003] Due to the application of PVC film, there is a PVC film with low temperature resistance requirements. In the prior art, the improvement of low temperature resistance and impact resistance is limited; in addition, impact modifiers such as chlorinated polyethylene, MBS, acrylic resin, etc. , weather resistance, whitening, flame retardancy, cost and other limiting factors make it impossible to achieve the desired effect in improving the performance of PVC film against extremely low temperature

Abstract

The invention discloses a cold-proof PVC film which is prepared from the following raw materials in parts by weight: 80 parts of a PVC resin powder, 10 parts of powdered rubber powder, 17.9 parts of dioctyl phthalate, 8 parts of titanium dioxide, 9.6 parts of dioctyl adipate, 3 parts of a thermal stability, 3.5 parts of a lubricant and 2 parts of epoxy soybean oil. The invention further disclosesa production method of the cold-proof PVC film. Due to adoption of the powdered rubber powder in the formula of the cold-proof PVC film disclosed by the invention, the cold resistance of the cold-proof PVC film in severe cold is improved, and the cold-proof PVC film disclosed by the invention is high in strength, good in tension property, relatively good in texture, simple in preparation method, convenient to manufacture and good in effect.

Description

technical field [0001] The invention relates to a PVC film, in particular to a cold-proof PVC film and a production method thereof. Background technique [0002] The main component of PVC film is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC film is also a kind of synthetic material that is loved, popular and widely used in the world today. The global usage of PVC film ranks second among various synthetic materials. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. [0003] Due to the application of PVC film, there is a PVC film with low temperature resistance requirements. In the prior art, the improvement of low temperature resistance and impact resistance is limited; in addition, impact modifiers such ...
