Abstract
The invention provides a PE wood-plastic wallboard and a preparation method thereof, and relates to the technical field of surface layer materials of wood-plastic products. The PE wood-plastic wallboard comprises a base material layer, a bonding layer and a surface layer which are sequentially stacked; the adhesive layer is made of an adhesive, and the adhesive is prepared from the following raw materials in parts by weight: 50-87 parts of polyethylene-methyl acrylate copolymer, 1-3 parts of low-density polyethylene, 5-15 parts of petroleum resin, 0-28 parts of diatomite and 0.1-1 part of antioxidant; the surface layer is made of a surface material containing siloxane. The bonding layer in the PE wood-plastic wallboard enables the base material layer and the surface layer to be tightly bonded, and improves the stability and the weather resistance of the product.
Description
Technical Field
The invention relates to the technical field of wood-plastic products, in particular to a PE wood-plastic wallboard and a preparation method thereof.
Background
The PE (polyethylene) wood-plastic wallboard is a product integrating functions and decoration, can decorate a building entity, improves the quality of an application environment, can endow the building with good application functions and various choices, and fully shows the decoration aesthetic effect of wood-plastic materials and the building. Therefore, the application of the PE wood-plastic wallboard in the field of outdoor wall decoration is rapidly raised.
When the PE wood-plastic wallboard is used on an outer wall facade, a scaffold needs to be lapped in the installation process, and if the quality of a product is poor, a large amount of manpower and material resources need to be consumed in the maintenance process. The existing PE wood-plastic wallboard is generally formed by bonding a surface layer and a core layer, but the bonding property of a co-extrusion surface layer material and a core layer material is poor, the phenomena of bubbling, delaminating and the like (as shown in figure 1) easily occur in the outdoor use process of the product, and the appearance of the product is seriously influenced. The bonding property of the surface layer and the core layer of the PE wood-plastic wallboard needs to be improved.
At present, the method for solving the problems is mainly to add the binder into the surface layer material in a melt blending mode, for example, ester and maleic anhydride grafting compatilizers are introduced to improve the bonding strength of the wood-plastic composite co-extrusion surface layer composite material and the core layer material, but the method has high requirements on the material mixing process, if the materials are not uniformly mixed, the phenomenon of local debonding can be caused, in addition, in order to achieve an ideal bonding effect, the using amount of the binder can be increased during blending modification, and the product cost is improved.
The problems of uneven flow and unstable discharge (as shown in figure 2) are very easy to occur in a complex co-extrusion flow channel in a commercially available hot melt adhesive product such as an EVA hot melt adhesive or an EAA hot melt adhesive, so that no report that the adhesion is increased by using the hot melt adhesive as a co-extrusion material exists at present, and the adhesion problem is still improved by mainly adopting a surface material blending modification mode in the prior art.
Disclosure of Invention
In view of the above, there is a need to provide a PE wood-plastic wallboard, in which the bonding layer tightly bonds the substrate layer and the surface layer, and improves the stability and weather resistance of the product.
