Abstract

The invention relates to a non-toxic degradable pvc zein winding film and a processing method thereof. Raw materials of the film comprise PVC resin, zein, calcium carbonate, titanium dioxide, chloroprene rubber, glyceryl stearate, acetylacetone, epoxidized soybean oil, a plasticizer, an ACR flexibilizer, Mbs, a liquid non-toxic barium-zinc composite stabilizer, an aluminate coupling agent, liquidparaffin and a proper amount of pigment or color master batch. According to the invention, environmental pollution is avoided; zein has unique film-forming property, zein is rich in sulfur-containingamino acids and protein molecules are connected through strong disulfide bonds and hydrophobic bonds, thus a basis is laid for easy formation of a film by zein, and when the concentration exceeds a certain value, protein is condensed, and hydrogen bonds, disulfide bonds and hydrophobic bonds for maintaining the net structure of the film are formed among the molecules, so that a transparent and glossy zein film is formed.

Description

technical field [0001] The invention relates to a film processing method, in particular to a non-toxic and degradable PVC zein winding film and a processing method. Background technique [0002] The use of agricultural film is very common, but most of the current plastic films are still non-degradable plastic films, so they pollute the environment. Although there are degradable films at present, they are expensive and inconvenient to be widely used. Contents of the invention [0003] The purpose of the present invention is to address the above problems, to provide a non-toxic and degradable PVC zein wrapping film and a processing method. [0004] The technical scheme adopted in the present invention is: [0005] A non-toxic and degradable PVC zein winding film, characterized in that it is configured according to the following parts by weight: 100 parts of PVC resin, 20-40 parts of zein, 5-15 parts of calcium carbonate, 3 parts of titanium dioxide ~10 parts, 5~8 parts of ...
