Abstract

The invention discloses a degradable environment-friendly plastic material. The degradable environment-friendly plastic material comprises, by weight, 60-70 parts of low-density polyethylene, 50-60 parts of high-density polyethylene, 10-13 parts of polypropylene, 3-5 parts of nano calcium carbonate, 1-3 parts of organosilicon materials, 5-8 parts of fire retardants (ammonium phosphate), 4-7 parts of flexibilizer (ethylene-propylene rubber), 3-5 parts of aluminic acid ester coupling agents, 1-1.5 parts of antioxidants 168 and 25-30 parts of modified soy protein. The technology for preparing the modified soy protein includes the following steps that 100 parts of soy isolate protein and 200-220 parts of tetrahydrofuran are weighed by weight, fed into a reactor and stirred, the mixture is heated in a water bath to 82 DEG C-89 DEG C, the water bath time is 25-30 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 environmentally friendly plastic materials, in particular to a degradable environmentally friendly plastic material. Background technique [0002] Polypropylene (PP) has developed extremely rapidly since its industrialization in 1957, and is a widely used plastic. The heat resistance of polypropylene is better than that of polyethylene, its melting point reaches 164°C, and it can be used for a long time at 100-120°C. Polypropylene also has excellent corrosion resistance and electrical insulation. Its mechanical properties, including tensile strength and compressive strength, are also very good. Its folding resistance is very prominent. However, polypropylene also has its shortcomings that need to be overcome urgently. After that, it is not easy to degrade, and the toughness and flame retardancy need to be improved urgently. Contents of the invention [0003] In order to solve the technical problems ex...
