Problems solved by technology

The disadvantages of this type of compound are that the synthetic process route is complicated, the product is expensive, the biodegradation process is slow, and some products are still dependent on petroleum.
The current research status of this type of compound mainly has the problems of a single variety of modified raw materials, a large gap between physical properties and synthetic plastics, etc.
[0006] Based on the research results at home and abroad, the main problems reflected are the lack of comprehensive understanding of the macromolecular properties and chemical functional groups of natural biomass materials, and the single purpose and use of modification
Causes serious defects in product application, and does not have the basic properties as a basic material
Up to now, there is no comprehensive and accurate discussion of biomass synthetic plastics

Abstract

The invention belongs to the field of material science, and in particular relates to a biomass synthetic plastic product and a preparation method thereof. The biomass synthetic plastic product is made of raw material A, water and auxiliary materials. The raw material A is composed of the following materials: vegetable protein powder, modified starch, acidity regulator, molecular structure modifier, and resin additives. The preparation of the biomass synthetic plastic realizes intensive utilization of energy on the basis of fully utilizing raw materials. Compared with traditional synthetic plastic products, biomass synthetic plastics have no significant difference in physical properties such as light transmittance, oxygen permeability, heat resistance, toughness, softness, elasticity and tensile strength, and have excellent anti-aging properties. For ordinary synthetic plastic products. It is inexpensive to manufacture and has excellent biodegradation properties.

Description

(1) Technical field [0001] The invention belongs to the field of material science, and in particular relates to a biomass synthetic plastic product and a preparation method thereof. (2) Background technology [0002] Since the invention of plastics in the 1850s, after more than 100 years of development, the plastics industry has become an important industry with a large scale and a wide variety of products. According to the latest statistics, the total output of plastics in the world has exceeded 180 million tons, and the consumption of synthetic resin, the main raw material for producing plastics, accounts for 72% of the three major synthetic materials. Plastic has become an important product indispensable to industrial production and people's life. [0003] However, with the rapid development of the plastics industry, the resulting environmental problems have become increasingly prominent. The waste of plastic products accounts for 10% of the total amount of urban garbag...
