High temperature-resistant full-degradable plastic film and preparation method thereof

Abstract

The invention discloses a high temperature-resistant full-degradable plastic film. The high temperature-resistant full-degradable plastic film is prepared from following raw materials, by weight, 60 to 65 parts of corn starch, 7 to 9 parts of nano montmorillonite, 0.6 to 0.7 part of peanut oil, 1.2 to 1.4 parts of tetrabutyl titanate, 12 to 14 parts of ramie straw, 30 to 35 parts of polyvinyl alcohol, 12 to 15 parts of trioctyl citrate, 1 to 2 parts of 2,6-tributyl-4-methyl benzol, 2 to 4 parts of polyimide, 4 to 6 parts of nano cerium oxide, and 2 to 3 parts of liquid silicon. According to a preparation method, the prior art is modified, the obtained preparation method is convenient for operation, and is beneficial for realization of industrial large-scale production; the raw materials are easily available; the obtained high temperature-resistant full-degradable plastic film possesses high temperature resistance and water resistance, is suitable to be taken as industrial packaging materials, and food packaging materials, can be made into clean bags, and is solid and durable; degradation can be realized under natural conditions after discarding; and no pollution is caused.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a high temperature resistant and fully degradable plastic film and a preparation method thereof. Background technique [0002] The output of my country's plastic film accounts for about 20% of the total output of plastic products, and it is one of the fastest growing categories of plastic products. As the demand for plastic films in my country's packaging, agriculture and other fields not only increases, it is expected that the demand for plastic films in my country will increase at a rate of more than 9% every year, and its market prospects are very broad. At present, the development of the traditional polymer material industry has slowed down due to the increasing cost of petroleum resources due to the increasing reduction of petroleum resources. Natural polymer materials are recyclable resources, which can be decomposed by microorganisms into substances that do not poll...
