Abstract

The invention relates to a composite material, and particularly relates to a waste tire rubber powder-filled plastic wood profile and a preparation method thereof. The waste tire rubber powder-filled plastic wood profile of the invention is prepared by the following raw materials by mass: 15%-75% of plastics, 10%-70% of wood fibers, 5%-40% of waste tire rubber powder, 5%-45% of a fire retardant, 1%-10% of a compatibilizer, 0.1%-3% of a lubricant, 0.5%-3% of a plasticizer, 0.05%-4% of an anti-oxidant, and 0.05%-2% of a vulcanizing agent. According to the invention, the plastic wood profile is filled with the waste tire rubber powder, which not only improves the resource utilization rate of waste tire rubber powder, develops new application technology of the rubber powder, extends the application scope of the rubber powder, but also provides good mechanical properties for the prepared plastic wood profile, greatly reduces the production cost of the plastic wood profile, and is expected to further extend the application fields of the plastic wood profile.

Description

technical field [0001] The invention relates to composite materials, in particular to a plastic wood profile filled with waste tire rubber powder 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 strength, and repeated recycling, and has been widely used in indoor and outdoor construction, transportation, packaging and other fields. [0003] In recent years, the recovery and utilization of waste tire rubber has become an urgent issue. The accumulation of a large amount of waste tire rubber not only causes a waste of resources, but also provides a place for the breeding of mice and mosqui...
