High-toughness regenerated environment-friendly plastic and processing process thereof

Abstract

The invention discloses a high-toughness regenerated environment-friendly plastic and a processing process thereof. According to the technical scheme, the plastic is characterized by comprising the following raw materials as components in parts by weight: 24-36 parts of a waste PVC (polyvinyl chloride) plastic, 22-46 parts of a waste ABS (acrylonitrile butadiene styrene) plastic, 28-34 parts of aPBT (polybutylece terephthalate) resin, 15-22 parts of an inorganic nano filler, 3-9 parts of a plasticizer, 4-10 parts of a toughening agent, 26-38 parts of a styrene-ethylene-butadiene segmented copolymer, 5-16 parts of a chain extender, 6-10 parts of a dispersant and 2.2-2.7 parts of an antioxidant. The effect of improving the toughness of a regenerated environment-friendly plastic can be achieved. The processing process of the high-toughness regenerated environment-friendly plastic comprises the following steps: S1, performing crushing; S2, performing cleaning; S3, performing drying; S4, weighing raw materials for later use; S5, firstly, mixing the waste ABS plastic with the chain extender so as to obtain a waste ABS plastic mixture; S6, mixing residual raw materials together, and performing external melting and mixing; S7, performing wire drawing molding; and S8, performing pelletizing.

Description

[0001] Technical field The present invention relates to the field of recycled plastics, in particular to a high-toughness recycled environmentally friendly plastic and its processing technology. Background technique [0002] At present, our country is in a stage of rapid economic development. Economic development means that a large amount of resources are consumed and a large amount of waste is generated. Nowadays, environmental issues are gradually getting people's attention. Recycling resources and developing circular economy will be an important shell. [0003] Plastic, a material with good processing properties and good usability, is used in all aspects of life, and the amount of waste plastics is also increasing sharply. Our country produces nearly 30 million tons of plastic waste every year, but the recycling rate is less than 10%. Most of the disposal methods are landfill and incineration. Due to the low density of plastic, landfill needs to occupy a large volume. In add...

Problems solved by technology

Our country produces nearly 30 million tons of plastic waste every year, but the recycling rate is less than 10%. Most of the disposal methods are landfill and incineration. Due to the low density of plastic, landfill needs to occupy a large volume. In addition, Due to the lack of microorganisms and enzymes that decompose plastics in nature, plastics cannot be degraded in the soil, and continue to exist in the form of macromolecules, becoming permanent garbage, which will affect the transfer of materials and heat in the soil and inhibit the growth of microorganisms
