Problems solved by technology

[0002] Polyethylene is a new type of engineering plastic with the best overall performance among engineering plastics. Because it has a very high relative molecular weight, it has many excellent properties that ordinary polyethylene materials do not have, such as: it is not easy to stick Attachment, chemical corrosion resistance, non-toxic, recycling, polyethylene also has its shortcomings that need to be overcome urgently, it is not easy to degrade, pollutes the environment after being buried, and the toughness and flame retardancy need to be further improved

Abstract

The invention discloses a degradable modified soy protein plastic material. The degradable modified soy protein plastic material comprises, by weight, 80-90 parts of low-density polyethylene, 20-30 parts of high-density polypropylene, 5-9 parts of low-density polypropylene, 3-8 parts of corn starch, 0.5-0.9 part of bacillus licheniformis, 3-12 parts of fire retardants (oligomeric ammonium phosphate), 5-10 parts of flexibilizer (ethylene-propylene- diene-terpolymer rubber), 2-5 parts of silane coupling agents, 0.5-1 part of antioxidant (phosphite ester) and 15-20 parts of modified soy protein. The technology for preparing the modified soy protein includes the following steps that 80-90 parts of soy isolate protein and 280-290 parts of tetrahydrofuran are weighed by weight, fed into a reactor and stirred, the mixture is heated in a water bath to 80 DEG C-85 DEG C, the water bath time is 20-30 min, the mixture is stirred for 10-15 min after adding 5-6 parts of zinc acetate and then evenly stirred after adding 18-20 parts of maleic anhydride, suction filtration is carried out after the reaction is completed, and the product is aired naturally to obtain the modified soy protein.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a degradable modified soybean protein plastic material. Background technique [0002] Polyethylene is a new type of engineering plastic with the best overall performance among engineering plastics. Because it has a very high relative molecular weight, it has many excellent properties that ordinary polyethylene materials do not have, such as: it is not easy to stick Attachment, chemical corrosion resistance, non-toxic, recycling, polyethylene also has its shortcomings that need to be overcome urgently, it is not easy to degrade, pollutes the environment after being buried, and the toughness and flame retardancy need to be further improved.
