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

Abstract

The invention discloses a polypropylene-nylon composite plastic thin film. The plastic thin film is composed of, by weight, 1-2 parts of zinc hydroxystannate, 17-20 parts of nylon 66, 0.1-0.3 part of gluconolactone, 1-2 parts of coco fatty acid diethanol amide, 210-300 parts of polypropylene, 7-9 parts of montmorillonite powder, 1-2 parts of lanthanum chloride, 0.3-1 part of silane coupling agent KH560, 2-3 parts of sodium carbonate, 1-2 parts of epoxy ethylhexyl stearate, 0.7-1 part of cetyltrimethylammonium chloride, 0.1-0.2 part of 2, 6-butylated hydroxytoluene, 4-6 parts of polyethylene glycol, 0.3-0.5 part of eucalyptus oil, 4-6 parts of propenol, 0.8-1 part of deca-brominated diphenyl ether, 1-2 parts of aluminum tripolyphosphate and 0.8-1 part of dimethyl formamide. The preparation method includes: performing flame-retardant modification on nylon; mixing with lanthanum-based montmorillonite powder after being amidated; performing blending modification through a silane coupling agent to enable functional filler to be effectively dispersed in polypropylene. Surface strength of the plastic thin film is improved.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a polypropylene nylon composite 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 ...
