Environment-friendly macromolecular plastic film and preparation method thereof

Abstract

The invention discloses environment-friendly macromolecular plastic film. The environment-friendly high-molecular plastic film is prepared from, by weight, 3-4 parts of fatty alcohol-polyoxyethylene ether, 210-300 parts of polypropylene, 7-9 parts of montmorillonite powder, 1-2 parts of lanthanum chloride, 0.7-1 part of casein, 2-3 parts of sodium carbonate, 4-6 parts of acetyl tributyl citrate, 0.4-1 part of sodium carboxymethyl cellulose, 3-5 parts of polyacrylamide, 2-4 parts of oxidized polyethlene wax, 0.5-1 part of lauryl dimethyl amine oxide, 4-5 parts of polyvinylpyrrolidone, 0.8-1 part of ricinoleic acid and 0.01-0.02 part of dodecyl glycoside. According to the plastic film, acetyl tributyl citrate is adopted as a plasticizer which is safe and free of toxin, and polyacrylamide is adopted to pretreat sodium salt so that sodium ions can be better combined with the montmorillonite powder; the macromolecular material polyvinylpyrrolidone is further added, the viscosity of modified polypropylene emulsion can be effectively adjusted, and the stability of the finished film is improved.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to an environment-friendly polymer plastic film and a preparation method thereof. Background technique [0002] At present, due to its good storage and portability, plastic packaging bags can quickly and efficiently store and transport products. They are more and more widely used in our daily production and life. Plastic films are now common daily necessities. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price, and is widely used in various industries. At present, the plastic film on the market is mainly polyethylene plastic film, but some products There will be problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film. Some plastic films are used for food packaging, but they contain toxic plasticizers, which affect the quality of food and endanger human ...

Problems solved by technology

[0002] At present, due to its good storage and portability, plastic packaging bags can quickly and efficiently store and transport products. They are more and more widely used in our daily production and life. Plastic films are now common daily necessities. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price, and is widely used in various industries. At present, the plastic film on the market is mainly polyethylene plastic film, but some products There will be problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film bubble

Some plastic films are used for food packaging, but they contain toxic plasticizers, which affect the quality of food and endanger human health
