Description

Technical Field

[0001] The co-extruded plastic wood board with colored flow patterns of the present utility model relates to a kind of board, belonging to the technical fields of composite materials and new materials. Background Art

[0002] The surface colors and patterns of the common plastic wood boards on the market are single, with poor decoration, and cannot match well with the decoration of places such as halls and buildings, so they are restricted to a certain extent when used in these places. Therefore, it is very necessary to invent a co-extruded plastic wood board with colored flow patterns, which has a certain decorative effect.

[0003] The co-extruded plastic wood board with colored flow patterns uses two extrusion devices to extrude raw materials with different formulations through different extrusion heads respectively, and then converge and co-extrude in a die. The obtained plastic wood board has a double-layer structure, namely its outer peripheral surface layer and internal structure layer. Each layer shows different properties due to the different raw materials used, so that the co-extruded plastic wood board has more excellent comprehensive properties than the plastic wood board extruded with a single formulation. The obtained co-extruded plastic wood board has colored flow patterns on the surface, and the structure layer has the characteristics of high strength and high hardness. At the same time, it is made of cheap raw materials and has a low cost. It can overcome the deficiencies of other plastic wood boards such as poor decoration and simple shape.
