Problems solved by technology

[0003] However, wood-plastic composite materials are flammable materials, and their flammability severely limits its application fields and hinders its development, making it a great safety hazard in combustion. At the same time, due to the gap between the mechanical strength and wood, the Its application in doors, windows, furniture and other structural components is relatively limited

Abstract

The invention discloses a preparation method of a basalt fiber reinforced flame-retardant wood-plastic composite material. The preparation method comprises the following steps: (1) carrying out modification treatment on basalt fibers; (2) paving a basalt fiber reinforced blank; and (3) carrying out hot press molding. The basalt fiber is subjected to special modification treatment, so that the surface activity of the basalt fiber is effectively improved, and the basalt fiber can form good interface bonding with other components of the wood-plastic composite material. Meanwhile, novel lignin-phosphorus series, lignin-nitrogen series and lignin-boron series mixed type environment-friendly flame retardants are added, and the rest components are reasonably added, so that the wood-plastic composite material finally has good flame retardance and the like. The basalt fiber reinforced flame-retardant wood-plastic composite material prepared by the invention has good comprehensive mechanical and flame-retardant properties, and the application field of the wood-plastic composite material is widened.

Description

Technical field [0001] The present invention belongs to the field of material processing, and is specifically related to the preparation method of basalt fiber reinforced flame retardant wood-plastic composites. Background technique [0002] The wood-plastic composite is wood fiber and a new type of composite obtained by thermally processed by a variety of plants and waste thermoplastics. Its appearance is conducive to ease the problem of lack of timber resources, effectively solve the resource utilization of natural and synthetic polymer material waste, and thus has received attention, and it has been widely used in the automotive industrial building industry, interior decoration, home appliances and transportation. Aspects in industries. The wood-plastic composite material has excellent comprehensive performance due to partial properties of the xerosometric material and the polymer material. [0003] However, the wood-plastic composite material is a flammable material, and the ...
