Problems solved by technology

[0003]However, for most plastic products, their tensile properties are not good, and they are often easily damaged by external forces
At the same time, since the main component of plastic is a high polymer that is difficult to degrade, it is easy to cause "white pollution" in the environment after being discarded, which will have a non-negligible negative impact on the ecological environment.

Abstract

The invention discloses a stretch-proof biodegradable plastic. The plastic is prepared from the following raw materials in parts by weight: 15-20 parts of acrylic resin, 30-40 parts of canna starch, 25-30 parts of bran powder, 55-65 parts of polytetrafluoroethylene, 20-25 parts of polytetramethylene ether glycol, 10-15 parts of dimethoxymethane, 10-15 parts of hexadienoic acid, 5-10 parts of zinc stearate, 5-8 parts of hyaluronic acid, 2-4 parts of triethanolamine, 1-2 parts of plasticizer and 1-3 parts of antioxidant. The plastic product prepared by the method has excellent stretching performance and can be easily degraded. Furthermore, the invention further discloses a corresponding preparation method.

Description

technical field [0001] The invention relates to the technical field of synthetic plastics, in particular to a stretch-resistant degradable plastic and a preparation method thereof. Background technique [0002] Plastic is a polymer compound made of monomer as raw material through addition polymerization or polycondensation reaction. It can freely change its composition and shape. It is usually composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, and pigments. and other additives. Plastic has many advantages, such as strong plasticity, good durability, light weight, etc., and is widely used in industrial production and daily life. [0003] However, for most plastic products, their tensile properties are not good, and they are often easily damaged under the action of external force. At the same time, since the main component of plastic is a high polymer that is difficult to degrade, it is easy to cause "white pollution" in the environment after be...
