[0023] Example 1: A sand willow / polyethylene wood-plastic composite material, which is composed of the following mass percentage components, with a particle size of 40-80 mesh sand willow wood powder 30%, polyethylene recycled material 30%, high density Polyethylene 30%, light calcium carbonate 6%, silane coupling agent 1%, PPA 1%, color masterbatch 2%, the total mass percentage of each component is 100%.

Example Embodiment

[0024] Embodiment 2: A manufacturing method of Salix / polyethylene wood-plastic composite material, which includes the following steps: (1) preparing Salix wood powder; (2) drying raw materials; (3) weighing raw materials in proportion; (4) ) Salix wood flour pretreatment; (5) stirring and heating; (6) extrusion granulation; (7) cutting and drying packaging; among them,

[0025] (1) Preparation of Salix wood powder: After uniformly slicing Salix with a salix slicer, the sand willow powder with a particle size of 40-80 mesh is obtained by grinding with a milling machine; Salix, a specialty of the Kubuqi Desert in Inner Mongolia, is selected. The growth environment of Salix psammophila is dry, windy and sandy, the wood fiber has high strength and toughness, and the moisture content is 5-8%;

[0026] (2) Raw material drying: drying the Salix wood powder obtained in the step (1) at a temperature of 105°C for 190 minutes, and drying the polyethylene at a temperature of 75°C for 40 minute...

Abstract

The invention discloses a salix psammophila/polyethylene wood-plastic composite material and a preparation method thereof. The salix psammophila/polyethylene wood-plastic composite material is prepared from the following ingredients in percentage by mass: 30-40% of salix psammophila wood powder with the granule diameter of 40-80 meshes, 30-40% of polyethylene, 15-30% of high density polyethylene, 2-6% of light calcium carbonate, 1-3% of coupling agent, 1-3% of lubricant and 1-5% color master batch. The preparation method of the salix psammophila/polyethylene wood-plastic composite material comprises the following steps of: (1) preparing the salix psammophila wood powder; (2) drying raw materials; (3) weighing the raw materials in proportion; (4) pretreating the salix psammophila wood powder; (5) stirring and heating; (6) carrying out extrusion granulation; and (7) cutting, drying and packaging. The salix psammophila/polyethylene wood-plastic composite material has the advantages of corrosion resistance, moisture resistance, easiness in preparation, high strength, good durability, strong adjustability, wide range of sources of raw materials, low cost and environmental pollution reduction.

Description

technical field [0001] The invention relates to a wood-plastic composite material and a manufacturing method thereof, in particular to a Salix salix / polyethylene 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 composite materials are generally made of waste plastics or new materials, mixed with waste wood and straw crushed materials, mixed and st...
