Abstract

The invention belongs to the technical field of degradable materials, particularly relates to a biodegradable material and a preparation method, and provides the following scheme aiming at the problems that an existing degradable material is relatively high in cost and a preparation method is complicated. The degradable plastic material comprises the following important components: 40-50 parts of a plant straw component, 6-8 parts of modified starch, 3-6 parts of degradable plastic resin, 3-6 parts of polystyrene, 2-4 parts of polyglycolic acid, 1.2-2.4 parts of a flexibilizer, 3-6 parts of a hydrophobic auxiliary agent, 2-5 parts of a liquid thickener, 0.3-0.6 part of an antioxidant and 0.3-0.6 part of a preservative, and the straw component comprises corn straw powder, wheat straw powder, rice straw powder and soybean straw powder. The mass ratio of the corn straw powder to the wheat straw powder to the rice straw powder to the soybean straw powder is 1: 1: 1: 1. The material is prepared from waste plant straw components so that the cost can be reduced, and the material has an environment-friendly function; the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a biodegradable material and a preparation method. Background technique [0002] Degradable materials are materials that can be degraded in a thermodynamic and kinetic sense over a period of time. According to the external factors of degradation, it can be divided into: photodegradable materials, biodegradable materials, etc. The main influencing factors are temperature, molecular weight, material structure, etc. Under the premise of environmental protection, degradable materials are very important. [0003] Existing degradable materials have high cost and complicated preparation methods. Contents of the invention [0004] The object of the present invention is to solve the disadvantages of high cost and complicated preparation method of existing degradable materials, and propose a biodegradable material and a preparation method. [0005] In order to achieve the...
