Problems solved by technology

In the application of plastics, people are paying more and more attention to the performance of plastics. The problem with many existing plastics is that they will produce toxic gases during processing, production and combustion, which will affect the health of production workers and cause pollution to the atmosphere. , and this kind of plastic waste will also pollute the environment

Abstract

The invention discloses an environment-friendly plastic containing modified starch. The environment-friendly plastic is composed of the following components in parts by weight: 45-60 parts of modified starch, 15-20 parts of polypropylene, 14-25 parts of acrylic resin, 20-28 parts of methylcyclohexane, 19-30 parts of propanediol butyl ether and 18-26 parts of diatomite, wherein the weight ratio of the modified starch to the polypropylene is 3: 1. The environment-friendly plastic is reasonable in formula, free of pungent smell and toxicity, hardly generates smoke in combustion, can be optically degradable after being discarded, and thus is environment-friendly; through detection, the environment-friendly plastic contains no lead, cadmium, polybrominated biphenyls or poly brominated diphenyl ethers, and has the mercury content of 500-800ppm and the hexavalent chromium content of 500-600ppm.

Description

technical field [0001] The invention relates to an environmentally friendly plastic containing modified starch, which belongs to the field of plastic materials. Background technique [0002] Plastic products can be used in many ways, such as motorcycle pedals, electronic products, track and so on. In the application of plastics, people are paying more and more attention to the performance of plastics. The problem with many existing plastics is that they will produce toxic gases during processing, production and combustion, which will affect the health of production workers and cause pollution to the atmosphere. , and this kind of plastic waste will also pollute the environment. Now more and more attention is paid to environmental protection, so the market for non-environmentally friendly plastics will become smaller and smaller, and only environmentally friendly plastics will have a broader market prospect. Contents of the invention [0003] Technical problem to be solve...
