A MULTI-COLOR WOOD-PLASTIC MOLDED MATERIAL, A PROCESS FOR PRODUCING THE SAME AND A WOOD-PLASTIC COMPOSITE BOARD

摘要

Provided is a multi-color wood-plastic molded material, which is made of a color masterbatch and a wood-plastic base material, wherein a ratio λ of a modulus of elasticity in tension (Et) of the color masterbatch to a modulus of elasticity in tension (Et) of the base material is from 0.26 to 1.47. A process for producing the multi-color wood-plastic molded material is also provided, comprising mixing and melt-extruding the color masterbatch and the base material. A wood-plastic composite board comprising the multi-color wood-plastic molded material is further provided. The multi-color wood-plastic molded material has two or more colors and exhibits a texture which is mixed and changes gradually and is similar to textures of natural woods on the outer surfaces and in the interior.
