Anti-aging plastic wood composite material and preparation method thereof

Abstract

The invention relates to a composite material, and particularly relates to an anti-aging plastic wood composite material and a preparation method thereof. The anti-aging plastic wood composite material of the invention is characterized in that the composite material is prepared by the following raw materials by mass: 20%-35% of plastics, 20%-70% of natural wood fibers, 5%-45% of a fire retardant, 1%-10% of a compatibilizer, 0.1%-3% of a lubricant, 0.5%-3% of a plasticizer, 0.1%-2% of a anti-aging filling material, and 0.5%-3% of a coloring agent. According to the invention, the reinforcing anti-aging filling material is added into the plastic wood composite material, which provides the plastic wood profile with both general functions and superpower anti-aging performance, effectively enhances the surface anti-aging performance of the plastic wood profile, and improves the service life of the plastic wood product.

Description

technical field

[0001] The invention relates to composite materials, in particular to an anti-aging plastic-wood composite material and a preparation method thereof. Background technique

[0002] Wood-plastic composite material is a new type of environmentally friendly composite material. It uses various waste natural wood fibers and plastics to compound, adds special additives, and extrudes a new type of environmentally friendly composite material that is both similar to wood and better than wood. . This material has the advantages of good dimensional stability, high specific strength, and repeated recycling, and has been widely used in indoor and outdoor construction, transportation, packaging and other fields.

[0003] It is precisely because of the many advantages of wood-plastic composite materials that the market has grown rapidly, and the rapidly expanding market has put forward higher performance requirements for wider applications of wood-plastic composite material...
