Microwave radioradiation crosslinked complete biodegradable material and its processing method

Abstract

The invention relates the microwave radio-frequency radiation cross-linking biodegradation material, comprising starch, cellulose, A, aminocaprolactam or polyatomic alcohol, B, coupling agent, C, nucleation agent, D, undecylenic acid, calcium carbonate, natrii chloridum, and urea. The method comprises the following steps: mixing the raw material, cross linking with microwave radio-frequency device, foaming, forming, and getting the product. The invention solves the problems of no degradation, complex procedure, high cost and hard technology. The product has the advantages of good draftability, suppleness and obstructing property. The invention has the advantages of wide application area, completely degradation and non pollution. The invention also has the advantages of simple technology, easy operation and low cost.

Description

technical field

[0001] The invention relates to a microwave radio frequency radiation cross-linked fully biodegradable material and a processing method thereof. Background technique

[0002] Traditional electrical packaging, tableware and plastic film, bags, bags and other molded packaging materials are mainly made of polystyrene, polypropylene, polyethylene, ethylene-vinyl acetate copolymer, polyvinyl alcohol and other raw materials, auxiliary fillers Generally, it is degradable starch, or photosensitizer, or foaming agent, etc. The production process generally adopts single or twin-screw granulation, and then extrudes and compresses tablets with an extruder, and finally undergoes positive / negative pressure suction and molding or tape casting. It mainly has the following disadvantages:

[0003] 1. The product cannot be degraded or cannot be completely degraded, it is difficult to recycle, and it will cause serious pollution to the environment.

[0004] 2. The product is ...
