A kind of polyvinyl chloride co-extruded wood-plastic board and preparation method thereof

Abstract

The invention discloses a polyvinyl chloride co-extrusion wood-plastic plate and a preparation method thereof. The co-extrusion wood-plastic plate comprises a core layer and surface layers located on the upper surface and the lower surface of the core layer. The core layer is prepared from PVC resin, a foaming agent, a wood-plastic material and auxiliaries. The surface layers are prepared from PVC resin. Due to the fact that the wood-plastic material is used in the core layer, the use amount and the raw material cost of PVC materials can be reduced, recycling can be achieved after the service life is reached, and the polyvinyl chloride co-extrusion wood-plastic plate is very environmentally friendly. The polyvinyl chloride co-extrusion wood-plastic plate has the strength and the finish degree of the surface of a co-extrusion foam plate and can be directly applied to the advertising industry, and printing can be directly conducted on the surface of the polyvinyl chloride co-extrusion wood-plastic plate. The polyvinyl chloride co-extrusion wood-plastic plate has the characteristics of a wood-plastic plate, nail holding power is better than that of the co-extrusion plate, and the polyvinyl chloride co-extrusion wood-plastic plate is widely used in the furniture industry, the decoration industry and the bathroom industry.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polyvinyl chloride co-extruded wood-plastic board and a preparation method thereof. Background technique [0002] Wood-plastic composite board is a high-tech green environmental protection material mainly made of wood and other fiber materials as basic materials, thermoplastic polymer materials and processing aids, etc., mixed evenly and then heated and extruded by mold equipment. It has the properties and characteristics of wood and plastic, and is a new type of composite material that can replace wood and plastic. With the gradual development of wood-plastic technology, wood-plastic panels are increasingly widely used, such as the furniture industry, interior decoration industry, vehicle and ship interior industry, and the future wooden house construction industry is the first choice for green and environmentally friendly panels, which will surely set off a new rev...
