Preparation process of wheat bran texture protein material capable of heat plastifying processing

Abstract

The present invention discloses a preparation process of wheat bran protein material capable of being thermoplastic processed. The preparation process includes adding reductant, degradable thermoplastic plastic and plasticizer into wheat bran protein powder, internal mixing, roll mixing or pugging to obtain the wheat bran protein material. The material may be further molded, extruded or injection molded to form packing article, tableware, etc. and the products may be naturally degraded without environmental pollution.

Description

technical field [0001] The invention relates to a preparation method of a thermoplastically processed wheat gluten protein material, which belongs to the fields of natural agricultural macromolecules, protein chemistry, macromolecular blending, macromolecular molding processing, and biodegradable materials. Background technique [0002] Synthetic polymer materials based on fossil fuels have been widely used in various fields and are closely related to people's lives. With the gradual depletion of these resources, synthetic polymers will face a shortage of raw materials. On the other hand, the refractory nature of petrochemical-based polymer materials has damaged the ecological system on the earth. Non-biodegradable plastics have low density, occupy a large number of landfills, and pollute the environment. Incineration, which is commonly used for plastic waste disposal, will produce a large amount of carbon dioxide, which will cause global warming, and the toxic gases produc...

AI Technical Summary

Problems solved by technology

Due to the poor plasticity of wheat gluten protein materials, the extrusion and injection molding processes commonly used in thermoplastic molding processing cannot be applied to the molding processing of wheat gluten protein materials, which limits the further application of this degradable and renewable natural agricultural polymer.
