Abstract

The invention discloses a heat-conducting plastic and wood composite material and a heating flooring manufactured by using the same, which belong to the technical field of short-flow composite material manufacturing processes and the technical field of building decoration materials. The invention is characterized in that: the heat-conducting plastic and wood composite material is formed by mixing heat-conducting plastic, composite wood meal and assistant according to a certain ratio and extruding the mixture in an extruder; and the heating flooring comprises a heating flooring body and is characterized by being manufactured by forming the heating flooring body by mold extrusion, injection or mold pressing of the heat-conducting plastic and wood composite material and manufactured by post processing by processes such as cutting, surface treatment and the like. Therefore, the heating flooring manufactured by using the heat-conducting plastic and wood composite material has the characteristics of high heat-conducting coefficient, high anti-deformation capacity, high thermal stability and high environment friendliness.

Description

technical field [0001] The invention relates to a heat-conducting plastic-wood composite material and a geothermal floor made of the same, belonging to the technical field of short-process composite material manufacturing technology and the technical field of building decoration materials. technical background [0002] Wood-plastic composite material refers to a new type of green environmental protection material made of wood fiber and thermoplastics through mixing and processing, also known as wood-plastic composite material and natural fiber composite material. In particular, it can use recycled plastics, crop fibers, and "three leftovers" in wood processing as raw materials, which is conducive to the comprehensive utilization of resources and resource conservation. It is also beneficial to the protection of forest resources and the ecological environment, fully recycles and utilizes recycled materials, and turns waste into treasure. It is of great significance. Especially...
