Problems solved by technology

[0002] The main components of the existing PVC wood-plastic composite materials on the market are generally wood powder and PVC resin. When the proportion of PVC resin increases, the toughness is better. The hardness of the existing wood-plastic materials on the market is relatively poor. It is easy to deform in the case of impact, and it is easy to appear pits in the case of impact, which will affect the functionality

Abstract

The invention relates to the technical field of composite materials and specifically relates to a high-strength wood-plastic composite material, a preparation method for the high-strength wood-plastic composite material, a sectional material of the high-strength wood-plastic composite material prepared by the preparation method and application of the prepared sectional material. The high-strength wood-plastic composite material contains PVC resin, a stabilizer, wood flour, filler, a processing aid, PE wax, EBS, stearic acid, a coupling agent and an impact modifier. The preparation method for the high-strength wood-plastic composite material comprises the following steps: (1) accurately weighing all raw materials according to a formula ratio; (2) firstly putting the weighed raw materials in a hot-mixing pot for stirring, and then, putting the hot-mixed material in a cold-mixing pot for stirring; and (4) putting the mixed mixture in an extruder, and carrying out extrusion molding from an extruder head, thereby preparing the sectional material of the wood-plastic composite material. The sectional material of the high-strength wood-plastic composite material is of a hollow strip sheet. The sectional material of the high-strength wood-plastic composite material serves as an auxiliary frame of doors and windows or a decorating material or a landscape viaduct or a rail fence or a fence rail.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a high-strength wood-plastic composite material and a preparation method of the high-strength wood-plastic composite material, and the profile and the finished profile of the high-strength wood-plastic composite material produced by the preparation method Applications. Background technique [0002] The main components of the existing PVC wood-plastic composite materials on the market are generally wood powder and PVC resin.
