Problems solved by technology

In recent years, the research and development direction of degradable plastics has mainly focused on using starchy agricultural products such as corn and soybeans as the main raw materials to make completely biodegradable plastic materials with high agricultural product content. However, this material is brittle, not resistant to water, Low tensile strength and other disadvantages, and the consumption of agricultural products is also relatively large, and extensive production and use is by no means beneficial to the current food security problems of human society

Abstract

The invention discloses a protein plastic material comprising the following raw materials in parts by weight: 45-50 parts of PBS (poly butylenes succinate), 30-35 parts of poly-beta-hydroxybutyric acid (PHB), 20-25 parts of peanut protein powder, 2.5-3 parts of potassium titanate fiber, 5-7 parts of silk fiber, 1.2-1.7 parts of a silane coupling agent KH570, 2-3 parts of sodium sorbate, 1.1-1.6 parts of ethyl p-hydroxybenzoate, 1.7-1.9 parts of diisooctyl phthalate (DIOP), 3-6 parts of epoxidized soybean oil, 3-5 parts of starch acetate, 15-18 parts of talcum powder, 7-11 parts of wollastonite powder, 5-9 parts of calcite powder and 1-1.4 parts of tert-butylhydroquinone (TBHQ). The protein plastic material disclosed by the invention can be decomposed by microorganisms, and is strong in ductility and good in impact resistance and oxidation resistance, the generation of white pollution can be avoided and the consumption of agricultural product resources can also be reduced.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a protein plastic material. Background technique [0002] As a non-renewable resource, petroleum is increasingly consumed. At the same time, the non-degradability of petroleum-based plastics has also caused serious pollution to the environment. According to statistics, waste plastics account for 7-8% of the total waste in developed countries. The development of degradable plastics can reduce white pollution and have significant economic and social benefits. In recent years, the research and development direction of degradable plastics has mainly focused on using starchy agricultural products such as corn and soybeans as the main raw materials to make completely biodegradable plastic materials with high agricultural product content. However, this material is brittle, not resistant to water, Low tensile strength and other disadvantages, and the consumption of agricultural product...
