Abstract

The invention provides a double-layer co-extruded aluminum-wood plastic profile and a preparation method. The profile comprises: an aluminum base material; an ethylene-1-butene copolymer layer, whichis coated on the aluminum base material; and a wood-plastic material, which is co-extruded on the ethylene-1-butene copolymer layer. The preparation method comprises the following steps: 1, mixing theraw materials of the wood-plastic material, and then performing granulation and extrusion granulation; and 2, heating the aluminum base material by heating equipment, then conveying the aluminum basematerial into a co-extrusion mold of co-extrusion equipment, coating the aluminum base material with the ethylene-1-butene copolymer and the wood-plastic material obtained in step 1 in a co-extrusionmode, fusing the contact surfaces of ethylene-1-butene and the wood-plastic material, and performing infiltrating on a wood-plastic base material layer, thus obtaining the aluminum-wood plastic profile. According to the invention, the wood-plastic material is combined with the aluminum base material, so that the mechanical properties of the product can be improved; compared with a common wood-plastic profile at present, the aluminum-wood plastic profile is not prone to deformation, the nail-holding power and the structural performance of the product are improved, and the wood-plastic profilehas the decorative performance and the structural performance of wood at the same time.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a double-layer co-extruded aluminum-wood-plastic profile and a preparation method. Background technique [0002] Wood-plastic composite materials are widely used in construction products, automobiles, gardens and outdoor facilities as a substitute for solid wood materials or pure plastics, and are developing rapidly. [0003] Wood-plastic profiles are non-toxic and have no harmful gases. They are the first choice for decoration. They are also waterproof and resistant to acid and alkali corrosion. They are green and environmentally friendly products that meet the requirements of modern society. It not only solves the problem of protecting forests and reducing the amount of wood, but also adjusts the formula and supporting materials of wood-plastic profiles according to various functional requirements to meet different physical and chemical performance requ...
