Environment-friendly plastic and preparation method thereof

Abstract

The invention discloses an environment-friendly plastic which is characterized by being prepared from the following raw materials in parts by weight: 15-25 parts of cinnamic acid modified plant fibers, 30-40 parts of vinyl beta cyclodextrin quaternary ammonium salt, 45-55 parts of 2-vinylpyrazine / methylvinylsilicate Fluorene / 1,3-adamantanediol monoacrylate copolymers, 1-2 parts of initiators, 4-6parts of epoxysuccinic acid and 5-8 parts of epoxy-terminated hyperbranched polyphosphate. The invention also provides a preparation method thereof. The environment-friendly plastic disclosed by the invention is excellent in comprehensive performance, good in mechanical property, water resistance, flame retardance and oxidation resistance, capable of being completely degraded after being discarded, and small in environmental influence.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environmentally friendly plastic and a preparation method thereof. Background technique [0002] In recent years, with the development of the field of polymer synthesis, plastic, one of the common polymer materials, has been widely used and has become an indispensable synthetic material in people's daily life. Plastic is a material that is polymerized by synthesis or condensation reaction using monomer raw materials. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Most plastics have the advantages of light weight, chemical stability, no rust, good impact resistance, and good insulation. [0003] With the continuous growth of plastic production, it brings convenience to people and also brings serious environmental pollution problems. Due to the characteristics of acid and alkali resistance, anti-o...

AI Technical Summary

Problems solved by technology

[0004] There are many types of environmentally friendly plastics in the prior art, such as polyaliphatic polyester, polylactic acid, microbial polyester, etc., but due to the difficulty in synthesis and high cost of these plastics, it is difficult to popularize and apply them in the market

In recent years, the research and development direction of environmentally friendly plastics has mainly focused on using starchy agricultural products such as corn and soybeans as the main raw materials to make completely biodegradable plastic materials with high agricultural product content. However, this material is brittle, not resistant to water, Low tensile strength and other disadvantages, and the consumption of agricultural products is also relatively large, and the widespread production and use is definitely not beneficial to the current food security problems of human society; in addition, there are more or less environmentally friendly plastics on the market. Disadvantages of fast decomposition rate, weak oxidation resistance, impact resistance and strong water absorption

[0005] The Chinese patent with the publication number CN101469061 discloses a method for producing biodegradable plastics from activated sludge, although it can also be realized through excess sludge, so that the excess sludge is finally converted into biodegradable plastics-polyhydroxyalkanoate, But the process is complicated, difficult to control, and it is very difficult to mass produce
