Embodiment 1

[0022] Take 40% coconut shell by weight, 20% multi-component textile fibers, 25% PE recycled materials, 10% wood flour, 5% fillers and additives, after removing impurities and homogenizing organic matter, and making coconut Mixing and volume reduction of shells, textile fibers and plastics, dispersion of fibers in plastics and formation of interfaces, granulation of fiber-plastic composites, etc., to prepare fiber-plastic composite particles.

Embodiment 2

[0024] Take 50% coconut shell by weight, 10% multi-component textile fibers, 25% PE recycled materials, 10% wood flour, 5% fillers and additives, after removing impurities and homogenizing organic matter, and making coconut Mixing and volume reduction of shells, textile fibers and plastics, dispersion of fibers in plastics and formation of interfaces, granulation of fiber-plastic composites, etc., to prepare fiber-plastic composite particles.

Embodiment 3

[0026] Take 60% coconut shell by weight, 25% PE recycled material, 10% wood powder, 5% filler and additives, after removing impurities and homogenizing organic matter, and combining coconut shell, textile fiber and plastic Mixing and volume reduction, dispersion of fibers in plastics and formation of interfaces, granulation of fiber-plastic composites, etc., to prepare fiber-plastic composite particles.

Abstract

The invention relates to the technical field of resource utilization of waste textiles and fiber reinforced composite materials, and discloses a fiber-plastic composite material directly utilizing renewable native fiber of tropical plants. The fiber-plastic composite material comprises the following components in percentage by weight: 40-60% of total textile fibers, and 25-45% of total plastic, with the balance being auxiliary materials. The components are compounded to obtain the fiber-plastic composite material. Through a specific formula, the optimal compounding state of the textile fibers and the plastic is realized, and the composite material has better strength and hardness.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a fiber-plastic composite material that can be directly utilized from the primary fibers of regenerated tropical plants. Background technique [0002] my country is a major producer of chemical fibers, textiles, and textiles (clothing, etc.), as well as a major consumer and exporter of textiles. A large amount of waste textiles are produced every year from the production and consumption ends. It is undeniable that the comprehensive utilization rate of waste textiles in my country is still lower than that of developed countries. In 2018, the total amount of fiber processing in my country was about 54.6 million tons, and more than 20 million tons of waste textiles were produced annually. In the same year, the comprehensive utilization of waste textiles in my country was about 3.8 million tons, and the comprehensive utilization rate was only 19%. [00...
