Elastic surface co-extruded wood-plastic profile and preparation method thereof

Abstract

The invention discloses an elastic surface co-extruded wood-plastic profile which comprises a core material layer, an elastic inner layer and an elastic surface layer, wherein the elastic inner layercomprises the following raw materials in parts by weight: 20-30 parts of natural rubber, 15-20 parts of polypropylene oxide polyols, 15-20 parts of high density polyethylene, 20-25 parts of poplar powder, 3-8 parts of a coupling agent, 2-5 parts of a compatibilizer, 3-5 parts of a plasticizer and 5-8 parts of calcium carbonate; the elastic surface layer comprises the following raw materials in parts by weight: 20-30 parts of high density polyethylene, 20-25 parts of poplar powder, 10-15 parts of an elastic material, 3-6 parts of a compatibilizer, 3-5 parts of a coupling agent, 2-3 parts of anantioxidant, 1-2parts of an ultraviolet-resistant agent and 2-4 parts of calcium carbonate. Designing of a double elastic layer of the co-extruded wood-plastic profile ensures that the co-extruded wood-plastic profile has high resilience, wear resistance and oxidation resistance, and the service life is significantly prolonged.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic profile materials and processing, and in particular relates to an elastic surface co-extruded wood-plastic profile and a preparation method thereof. Background technique [0002] At present, in the field of decoration, indoor ground pavement materials are generally various wooden floors or composite wood floors. The foot feeling of the wooden floor is relatively comfortable, but problems such as expansion deformation, warping and cracking often occur during use. The wood-plastic floor is a new type of environmentally friendly wood-plastic composite material product, which is mainly composed of wood powder plant fibers, thermoplastic polymer materials and processing aids, etc., mixed evenly and then heated and extruded by mold equipment. High-tech green and environmentally friendly materials, which have both the performance and characteristics of wood and plastics, can replace wood and plasti...

AI Technical Summary

Problems solved by technology

The floor of the basketball court requires good anti-slip performance and cushioning performance, while the existing wood-plastic floor has poor elasticity, poor adhesion, and is prone to aging, cracking and wear

If the surface is too soft, although it has good resilience, the hardness often does not meet the actual requirements, which will lead to poor foot feel, easy wear, and easy aging.
