Abstract

The invention relates to the technical field of resource utilization of waste textiles and fiber reinforced composite materials, and discloses a composite packaging material fiber-plastic composite material, which comprises a composite packaging material, textile fibers, plastics and auxiliary materials, and is prepared by compounding the following components in percentage by weight: 40-60% of total fibers, 25-45% of total plastics and the balance of auxiliary materials. Through a specific formula, the optimal composite state of the textile fiber 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 composite packaging material fiber-plastic composite material. Background technique [0002] Paper-plastic-aluminum composite packaging is a packaging system based on food-specific cardboard, and is a composite paper packaging made of polyethylene, paper, and aluminum foil. [0003] 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 comprehen...
