Transparent tear-resistant high-grade plastic thin film and preparation method thereof

Abstract

The invention discloses a transparent tear-resistant high-grade plastic film, which is composed of the following raw materials in parts by weight: 0.1-0.2 butyltin mercaptide, 3-4 dibutyltin dilaurate, 210-300 polypropylene, chlorinated Lanthanum 1-2, sodium carbonate 2-3, ethoxylated alkyl ammonium sulfate 0.4-1, nanometer calcium carbonate 2-3, methyltriethoxysilane 0.1-0.16, abietyl alcohol 3-4, 8-hydroxy Quinoline copper 0.3-0.4, polymaleic anhydride 2-3, triethylene glycol diisocaprylate 7-10, phytate 0.1-0.2, palm wax 1-3, polyimide 2-4, Montmorillonite powder 7-9. In the present invention, dibutyltin dilaurate is dissolved into the plasticizer, and then blended with butyltin mercaptide to obtain an auxiliary agent with excellent lubricity, transparency, and weather resistance, which is mixed with polyimide , further improving the strength and weather resistance of the additives, the plastic film of the present invention has high surface strength, good mechanical properties, and strong transparency, and is especially suitable for the outer packaging material of high-grade gifts, with good protection.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a transparent tear-resistant high-grade 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 endange...
