Problems solved by technology

In the process of logistics packaging industry, the current wood-plastic packaging materials have poor elastic properties, which makes the hard contact between products and packaging easy to damage products, and the flame retardant effect is not good. A large number of stacked products and packaging materials are prone to fire in hot summer ,There are security risks
Therefore, wood-plastic materials currently on the market cannot meet consumer demand

Abstract

The invention discloses a preparation method of a high-elasticity flame-retarding wood-plastic packaging material. The preparation method comprises the following steps: crushing plant fibers and carbon fibers into powder, and carrying out surface organic modification; mixing aluminum silicate, polyvinyl chloride, polypropylene, polybutylene succinate and tributyl phosphate, adding into a blending machine and stirring and reacting for 20min to 40min; extruding an obtained mixture through an extruder, and granulating in a granulating machine; adding cerium phosphate, linalool and polyphenylene sulfide fibers, and carrying out ultrasonic reaction for 30min to 40min; filtering and drying to obtain grains; putting the grains into a mold, and carrying out film pressing and molding to obtain the high-elasticity flame-retarding wood-plastic packaging material.

Description

technical field [0001] The invention belongs to the field of wood-plastic packaging materials, in particular to a highly elastic flame-retardant wood-plastic packaging material and a preparation method thereof. Background technique [0002] In recent years, the global forest resources are becoming increasingly depleted, the awareness of environmental protection is increasing day by day, and higher requirements are put forward for the application of wood. In order to save resources, improve the utilization rate of wood and plastics, and overcome the difficulties faced by the plastics and wood industries. In recent years, with the development of science and technology, a new type of composite material, wood-plastic composite material, has emerged. Wood-plastic composite material refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin adhesive, and more than 50% of waste plant fibers such as wood powder, rice husk, straw, etc. ...
