Abstract

The invention discloses a preparation method of a rubber seed shell-based wood-plastic composite material and belongs to the technical field of processing of polymer materials. The rubber seed shell-based wood-plastic composite material is mainly processed from the raw materials including rubber seed shells, recycled plastics, coupling agent, lubricating agent, antioxidant and the like by steps of high-temperature mixing, pelletizing, extrusion molding, cooling, cutting and the like. The rubber seed shell-based wood-plastic composite material disclosed by the invention has good mechanical performances, a low water absorption and aging resistance, so that performance requirements of international wood-plastic floors and international wood-plastic decorative sheets are reached, and therefore, the rubber seed shell-based wood-plastic composite material can be applied to the fields such as outdoor flooring, landscape wood, furniture and packaging. Moreover, the main materials of the rubber seed shell-based wood-plastic composite material are residues of rubber seed oil and recycled plastics, and therefore, the preparation method belongs to comprehensive utilization of waste resources.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a wood-plastic composite material prepared from rubber seed shells and recycled polyolefin plastics and a preparation method thereof. Background technique [0002] Wood-plastic composite materials are made by mixing lignocellulose fibers, plastics and additives such as lubricants, coupling agents, antioxidants, and pigments, and processed by extrusion, molding, or injection molding, which are suitable for mass production. a new type of material. Wood-plastic composite materials have the characteristics of both wood and plastic. They have the advantages of excellent mechanical properties, low water absorption, and easy processing. , outdoor buildings, etc. [0003] The use of waste lignocellulosic raw materials or crop straw raw materials to produce wood-plastic composite materials has received widespread attention. Wood powder (invention name: a method...
