Environmentally-friendly biodegradable plastic

Abstract

The invention discloses an environmentally-friendly degradable plastic, which is composed of the following components in parts by weight: polyethylene, polyvinyl chloride, polypropylene, polystyrene resin, polyolefin resin, polylactic acid, a solubilizer, an antistatic agent, modified starch, modified plant fiber, and waste recycled plastic pellets; the raw materials are mixed in proportion and extruded in an extruder to obtain plastic pellets which are environmentally-friendly degradable plastics, and processing in the next process is carried out. The environmentally-friendly degradable plastic is mainly prepared by using low density polyethylene, polyvinyl chloride, polypropylene, polystyrene resin and added various auxiliary materials, by optimizing the ratio of each component, the prepared environmentally-friendly plastic has the advantages of high strength, excellent toughness, good heat resistance, strong antistatic ability, and good environmentally-friendly plastic stability. The added modified starch and modified plant fiber can increase the degradation rate, and the use of waste recycled plastic pellets can fully use waste plastics, and the environmentally-friendly degradable plastic reduces production costs and further protects the environment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environmentally friendly degradable plastic. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as plexiglass,...

Problems solved by technology

[0003] However, the common plastics in the existing market are not conducive to recycling, and reclassification is very difficult, and it is not economically cost-effective; when plastics are burned, toxic gases are generated, and in high-temperature environments, plastics will decompose and produce toxic components; plastics are refined from petroleum The products are made of petroleum, and petroleum resources are limited; because plastics are not biodegradable, the "white pollution" caused by waste plastics is becoming more and more serious
