AI Technical Summary

Problems solved by technology

[0005] However, the compounding of bamboo fiber and plastic still faces many technical problems, such as bamboo fiber is highly polar and has good hydrophilicity, while plastic is non-polar and has strong hydrophobicity, resulting in poor compatibility between bamboo fiber and plastic. The interface adhesion is small, which affects the composite performance of bamboo-plastic composites
In addition, the complexity of the composition of bamboo fiber itself also determines the difficulty of forming and processing bamboo-plastic composite materials. For example, as the proportion of bamboo fiber increases, the processing fluidity and mechanical properties will decrease, and products with complex shapes cannot be produced.

Description

Technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a bamboo-plastic composite material and a preparation method and application thereof. Background technique [0002] With the advent of environmental protection and economic times, composite materials with low cost, good performance and certain environmental compatibility have increasingly broad market prospects. In recent years, the advantages of natural plant fibers as reinforcing materials have attracted more and more public attention. Because it not only has the advantages of abundant resources, low price, lower density than other inorganic fibers, and similar modulus and tensile strength to inorganic fibers, but also has the characteristics of repeated processing, not easy to absorb moisture, and biodegradable. my country is rich in bamboo resources and is known as the "Bamboo Kingdom". As a type of plant fiber, bamboo fiber has its own characteristics. It has...
