Abstract

The invention discloses a preparation method of a wood-plastic composite material aid. The aid is aluminum oxide-aluminum nitride composite heat-conducting ceramic composed of aluminum oxide heat-conducting ceramic and aluminum nitride heat-conducting ceramic. The preparation method mainly comprises the following steps: ball milling, calcination, ball milling, granulation, sintering, pulverization and the like. By adding the aluminum oxide-aluminum nitride composite heat-conducting ceramic, the wood-plastic composite material can have favorable mechanical properties and low water absorptivity, and thus, has wider application range and longer service life. Besides, the aluminum oxide-aluminum nitride composite heat-conducting ceramic has a certain porous structure, and thus, can adsorb harmful gas and purify air, thereby being beneficial to environmental protection. Therefore, the preparation method of the wood-plastic composite material aid has great development potential.

Description

technical field [0001] The invention relates to a preparation method of wood-plastic composite material additives, belonging to the technical field of composite materials. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) use thermoplastics as a matrix, pretreated plant powder or wood fiber as a filler or reinforcement, and are mixed with various additives required in a certain proportion. A composite material prepared by extrusion, lamination, molding or injection molding. It has good elastic modulus, compression resistance, bending resistance, durability and other properties, and also has the characteristics of raw material resources, cost economy, product plasticization, environmental protection and recycling. Therefore, wood-plastic composite materials are widely used in many fields. [0003] At present, research on wood-plastic composites focuses on improving interfacial compatibility and improving processing technology to obtain mat...
