Abstract

The invention provides a wood-plastic composite material applicable to outdoor doors and windows and a preparation method thereof. The composite material is prepared from plastic particles, fiber composite particles and an additive, wherein the fiber composite particles contain plant fibers, basalt fibers, carbon fibers and hemp fibers and also contain silicon oxide nano powder, inorganic filler,nano sepiolite powder, zinc stearate, calcium stearate and red mud; the components are added to prevent the material from being cracked and deformed; the toughness of the material is improved and theservice life is prolonged; meanwhile, the material can prevent fading, and original color and quality are kept. According to the wood-plastic composite material provided by the invention, the siliconoxide nano powder and the nano sepiolite powder are added so that the cost of a product is greatly reduced under the condition that all performance indexes meet national standard requirements.

Description

technical field [0001] The invention belongs to the technical field of door and window materials, and in particular relates to a wood-plastic composite material suitable for outdoor doors and windows and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, more and more people pay attention to wood-plastic composite materials that are environmentally friendly, renewable, and recyclable. Wood-plastic composite materials have homogeneous materials, stable dimensions, and are not easy to produce Cracks, warping, and no defects such as wood knots and twills; it has the processability of thermoplastics, extrusion, molding, injection molding and other processes can be used for molding, and the equipment wears little; light weight, low energy consumption for production; processing Convenient, can be sawed, planed and bonded or fixed with nails and bolts; no need to use toxic chemical sub...
