Problems solved by technology

The matrix of wood-plastic composite materials usually chooses thermoplastic materials, and the filler is wood powder. Due to the large difference in polarity between the two phases, the interfacial compatibility of the materials improves the mechanical strength of the materials. The common one in CCCC is silane coupling. Due to the particularity of coupling agents, maleic anhydr

Abstract

The invention discloses a wood-plastic composite material and a preparation method thereof. The wood-plastic composite material comprises the following raw materials in part by weight: 30 to 50 percent of saw dust, 30 to 50 percent of waste polyethylene, 5 to 20 percent of waste polypropylene, 5 to 10 percent of aluminate, 0.5 to 1 percent of modifier, 4 to 5 percent of stearic acid, 0.5 to 1 percent of zinc stearate and 4 to 5 percent of ethylene wax. The preparation method comprises: weighing raw material; drying the saw dust; mixing, filling the waste polyethylene and waste polypropylene in an open mill, adding the modifier, stearic acid, zinc stearate and ethylene wax, plasticizing and sheeting to obtain a plasticized blank; and shearing the plasticized blank into small thin sheets, subjecting the small thin sheets to hot-forming, preparing a standard sample, removing flashing, and performing secondary hot-forming to obtain wood-plastic composite material. The wood-plastic composite material has high compatibility, interface compatibility and good mechanical properties and brings great convenience for production and life.

Description

A kind of wood-plastic composite material and preparation method thereof technical field The invention relates to a wood-plastic material, in particular to a wood-plastic composite material and a preparation method thereof. Background technique Wood-plastic composite material is an emerging environment-friendly material. Due to the recyclability of raw materials and products and the increasing shortage of forest resources, wood-plastic composite materials have developed rapidly in recent years. Compared with traditional materials, wood-plastic The product has the advantages of wood-like appearance, higher hardness than plastic, and excellent molding processability. The matrix of wood-plastic composite materials usually chooses thermoplastic materials, and the filler is wood powder. Due to the large difference in polarity between the two phases, the interfacial compatibility of the materials improves the mechanical strength of the materials. The common one in CCCC is silane...
