Abstract

The invention discloses a plastic thin film and a preparation method thereof. The plastic thin film is prepared from the following raw materials in parts by weight: 40 to 70 parts of polyvinyl chloride, 40 to 60 parts of acrylic resin, 8 to 13 parts of polyethylene wax, 10 to 18 parts of talcum powder, 5 to 9 parts of organized montmorillonite, 30 to 50 parts of polyvinyl alcohol, 8 to 16 parts of sodium-titanium phosphate, 12 to 24 parts of polyacrylamide, 1.5 to 3 parts of dicumyl peroxide, 1 to 3 parts of antioxidants, 8 to 13 parts of calcium carbonate, 0.3 to 0.7 part of silane coupling agents, 8 to 13 parts of dioctyl phthalate, 1 to 3 parts of light stabilizers, 3 to 7 parts of glyceryl tristearate, 1.5 to 5 parts of styrene-acrylonitrile copolymers and 0.8 to 1.8 parts of plasticizing agents. Compared with the prior art, the plastic thin film has the advantages that the tensile strength of the plastic thin film is high; the preparation process is simple.

Description

technical field [0001] The invention belongs to the field of film materials, in particular to a plastic film and a preparation method thereof. Background technique [0002] Plastic films are mainly used for packaging and as lamination layers. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. However, the tensile strength of existing plastic films is relatively poor, and it is difficult to meet the requirements of people's life and industrial production. Contents of the invention [0003] The purpose of the present invention is to provide a plastic film and its preparation ...
