Abstract

The invention discloses an externally filled and prefabricated wood-plastic plate, which comprises a wood-plastic plate, an interface adhesive, a priming coat, a top coat or a true stone coating and a face protective paint, wherein the surface on one side or the surfaces on both sides of the wood-plastic plate are grinded to a rough surface/rough surfaces, the interface adhesive is coated on the surface of the wood-plastic plate grinded to the rough surface, the priming coat is coated on the interface adhesive, the top coat or the true stone coating is arranged on the priming coat, and the face protective paint is coated on the top coat or the true stone coating.

Description

Technical field: [0001] The present invention relates to building or decorative panels made of wood-plastic material. Background technique: [0002] Existing wood-plastic building wall panels or decorative panels manufactured by combining polymer materials and wood powder are not suitable for long-term outdoor use as wall materials because the polymer materials and wood powder are prone to aging and fading. Invention content: [0003] The purpose of the present invention is: 1, the surface of wood-plastic plate is ground into rough surface and coated with interface adhesive or the surface of wood-plastic plate is processed into dovetail groove, and the convex surface of dovetail groove and in the groove are ground into rough surface and coated with interface adhesive, Solve the problem of the bonding fastness between the wood-plastic board and the base coat, and prevent the wood-plastic board from separating from the base coat. 2. The surface of the wood-plastic board is ...
