Salix mongolica/polyvinyl chloride wood-plastic composite material and production method thereof

Abstract

The invention discloses a salix mongolica / polyvinyl chloride wood-plastic composite material and a production method thereof. The salix mongolica / polyvinyl chloride wood-plastic composite material comprises the following components in parts by mass: 100 parts of polyvinyl chloride, 40 parts-60 parts of salix mongolica wood powder, 2 parts-6 parts of coupling agent, 3 parts-5 parts of lead salt compound stabilizer, 0.3 part-0.7 part of calcium state, 0.1-0.3 part of stearic acid, 0.1-0.4 part of paraffin and 1 part-4 parts of chlorinated polyethylene. The production method of the salix mongolica / polyvinyl chloride wood-plastic composite material comprises the following steps of: (1), preparing the salix mongolica wood powder; (2), drying the raw materials; (3) weighing the raw materials according to proportions; (4) pretreating the salix mongolica wood powder; (5) stirring and heating; (6) extruding and pelleting; and (7) cutting, drying and packaging. The salix mongolica / polyvinyl chloride wood-plastic composite material has the advantages of corrosion resistance, moisture protection, easiness in processing, high strength, good durability, strong adjustability, wide source of raw materials, low cost and capability of reducing environmental pollution.

Description

technical field [0001] The invention relates to a wood-plastic composite material and a manufacturing method thereof, in particular to a Salix salix / polyvinyl chloride wood-plastic composite material and a manufacturing method thereof. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then plates or profiles produced by extrusion, molding, injection molding and other plastic processing techniques. Mainly used in building materials, furniture, logistics packaging and other industries. [0003] At present, wood-plastic materials are generally made of waste plastics or new materials, mixed with waste wood and straw crushed materials, mixed and stirre...

AI Technical Summary

Problems solved by technology

[0003] At present, wood-plastic materials are generally made of waste plastics or new materials, mixed with waste wood and straw crushed materials, mixed and stirred, and directly poured into molds for compression molding or extrusion and granulation, followed by extrusion and injection molding. Due to the use of waste wood And the length and thickness of the straw are different, the particle size is different, and the source of the material is unstable. It is necessary to increase the classification, cleaning, crushing and other processes and related equipment, which will increase the cost and cause the product quality to be unstable and the physical and chemical properties to be poor.
