A kind of preparation method of bamboo fiber molding composite material

Abstract

The invention provides a preparation method of bamboo fiber molding composite material. The method is as follows: after rolling bamboo chips into a loose shape, immersing them in a nano-calcium carbonate solution, adding a chelating agent, and performing flash explosion treatment to obtain modified bamboo Fiber crude product, filter the residual solution to obtain the crude product of bamboo basic tissue, immerse the crude product of bamboo fiber in the nano-calcium carbonate solution for ultrasonic treatment, obtain modified bamboo fiber, filter the residual solution to obtain the crude product of bamboo basic tissue, merge the crude product of bamboo basic tissue twice, wash with water drying to obtain the basic structure of bamboo, soaking in water, adding a thickener, stirring and filtering to obtain the basic structure of modified bamboo, mixing the dried modified bamboo fiber and the basic structure of modified bamboo, and molding to obtain a bamboo fiber mold plastic composites. The bamboo fiber molding composite material of the invention has good uniformity, high fiber yield, and can effectively utilize the basic structure of bamboo to realize high-efficiency utilization of bamboo.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a preparation method of bamboo fiber molding composite material. Background technique [0002] my country is the country with the most abundant bamboo resources in the world. Bamboo fiber is a new type of resource, which is widely used in industries such as daily necessities, papermaking, textiles, and construction, especially the use of paper fibers to make molded composite materials. High strength, degradable and environmentally friendly. With the implementation of the "Plastic Ban", bamboo fiber molded products can replace plastics to make disposable environmental protection lunch boxes, water cups, packaging materials, etc. [0003] At present, the preparation methods of bamboo fiber mainly include physical mechanical method, chemical method, biological enzyme method, etc., although the physical mechanical method is simple in process operation, the proce...

Problems solved by technology

[0003] At present, the preparation methods of bamboo fiber mainly include physical mechanical method, chemical method, biological enzyme method, etc., although the physical mechanical method is simple in process operation, the processing time is long, the bamboo fiber obtained is thick and hard, and the degumming effect is not good; the chemical method fiber processing time short, but it will cause great damage to certain properties of bamboo fiber, especially the existing processing technology is poor in environmental protection, which is not conducive to long-term development; biological enzyme method has the advantages of mild action conditions, but due to strong enzyme specificity and high production process requirements, Enzyme hydrolysis efficiency is low
