Abstract

The invention discloses a halogen-free flame-retardant wood-plastic co-extrusion composite material and a preparation method thereof. The halogen-free flame-retardant wood-plastic co-extrusion composite material comprises a core layer and a halogen-free flame-retardant surface layer for coating the core layer, wherein the core layer comprises plant fibers, PE plastic, a compatilizer, an antioxidant, a lubricant and an inorganic filler, and the halogen-free flame-retardant surface layer comprises PE plastic, modified polypropylene fibers, an ethylene-methacrylic acid copolymer, hypophosphite, zinc borate, an interface modifier, a light stabilizer, an antioxidant and other auxiliaries. The halogen-free flame-retardant wood-plastic co-extrusion composite material disclosed by the invention isvery simple to prepare, the core layer granules and the halogen-free flame-retardant surface layer granules are firstly prepared respectively, and then co-extrusion molding is carried out. The halogen-free flame-retardant wood-plastic co-extrusion composite material has the advantages of excellent flame retardancy, high strength, excellent impact resistance, high hardness, favorable wear resistance, low water absorptivity, favorable aging resistance, favorable wear resistance, favorable scratch resistance, high wood texture and favorable antiskid effect, and is not easy to fade or mildew whenbeing used outdoors.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant wood-plastic co-extruded composite material and a preparation method thereof, belonging to the technical field of wood-plastic composite materials. Background technique [0002] Wood-plastic composite material is a new composite material made by mixing plastics such as polyethylene, polypropylene and polyvinyl chloride with plant fibers such as wood powder, rice husk and straw. In recent years, wood-plastic composite materials have developed very rapidly. They are used in packaging boxes, automotive interior parts, outdoor decking, fences, furniture, doors and windows, etc. The scope of application can cover almost all logs, plastics, plastic steel, aluminum alloys and Other fields where similar composite materials are currently used. At the same time, because wood-plastic composite materials have natural resources and environmental protection advantages, and meet the requirements of sustainable ...
