Formulation of wood-plastic profile as well as preparation method and manufacturing device thereof

Abstract

The invention particularly relates to a formulation of wood-plastic profile as well as a preparation method and a manufacturing device thereof. The formula is characterized by being prepared from the following raw materials in parts: 100 parts of PP waste plastic with good mobility, 20 to 75 parts of wood powder, 5 to 15 parts of flexibilizer; 2 to 10 parts of compatibilizer; 1 to 10 parts of lubricant; 0.1 to 1 part of main antioxidant; 0.1 to 0.5 part of auxiliary antioxidant; 0.02 to 0.5 part of light stabilizer and 0.1 to 4 parts of antibacterial agents; the preparation method is characterized by comprising the following steps:(1) recycling the PP waste plastic with good mobility; (2) cleaning, crushing and drying; 3) drying the wood powder; 4) extruding and granulating; and 5) extruding and molding; and the manufacturing device is characterized by comprising a plastic cleaning device, a wood powder drying device, a weighing device, a mixing device, an extrusion granulation device and an extrusion molding device. The invention has the advantages of low cost, durability, long life, good heat resistance, good resistance to ultraviolet rays, high hardness and high load capacity.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, and in particular relates to a formula of wood-plastic profiles, a preparation method and a manufacturing device thereof. Background technique [0002] Wood-plastic composites (WPC) use plant fibers as the main raw material (such as wood powder, straw, etc.), and after surface activation treatment, they are combined with various plastics (such as polyvinyl chloride, polyethylene, polypropylene, etc.) and additives according to certain conditions. It is a new type of composite material made by injection molding, extrusion molding, compression molding and other processes after mixing in a certain proportion. The wood-plastic composite material has excellent performance, a wide range of applications, and is conducive to environmental protection. However, the current wood-plastic composite materials also have some defects, mainly as follows: (1) high cost; (2) high density, u...
