Abstract

The invention relates to a method for preparing a fibrilia felt improved soybean protein matrix composite material. The method comprises the following steps of: firstly, preparing fibrilia into a fibrilia felt via degumming, carding and hot pressing; mechanically mixing the soybean protein and plasticizer according to a certain proportion, and sealing and balancing the mixed soybean protein and plasticizer under room temperature for a certain period; and then, spreading the fibrilia felt into multi-component matrix of the soybean protein and the plasticizer; finally, acquiring the soybean protein matrix composite material via a molding method or a hot press molding method. The fibrilia felt improved soybean protein matrix composite material has the advantages of wide source of raw materials, regenerative degradation, low cost, safety and innocuity, simple and controllable preparation method of the composite, good chemical property and high water resistance. Compared with the soybean protein material only using the plasticizer, the fibrilia felt improved soybean protein matrix composite obviously improves chemical property. Therefore, the composite material is a novel material which can be completely degraded with development potential.

Description

technical field [0001] The invention relates to a preparation method of soybean protein-based composite material reinforced by hemp fiber felt. Background technique [0002] As we all know, the world's oil reserves are decreasing day by day, and the world's output of polymer materials that use petroleum products as raw materials continues to grow rapidly, which means that the increasing production of polymer materials and the rising energy consumption together require more Petroleum resources. [0003] In addition, the non-degradability of petroleum-based polymers has caused great pressure on environmental protection. About 30% of global plastic production is used as packaging materials, and most packaging materials or agricultural film materials become waste after one use. Due to the large amount of light weight, difficult to degrade, and incineration at will, it has become a shocking "white pollution" over time. Plastic waste degrades the environment, it causes acid rai...
