Embodiment 1

[0032] S1: first crush the plant fiber into wood powder;

[0033] S2: Put the wood powder in S1 and other component raw materials into the mixer according to the weight ratio, and mix for 30 minutes at 90°C and 120rpm.

[0034] S3: Add the mixture obtained in S2 into an extruder, extrude and granulate at an extrusion temperature of 170°C and a screw speed of 30rpm;

[0035] S4: The granules obtained in S3 are molded by a mold at a temperature of 180° C. and a pressure of 10 MPa, cooled, drawn, and cut.

[0036] The particle size of the wood flour in the above step S1 is 20 mesh to 200 mesh.

Embodiment 2

[0038] The difference from Example 1 is that the temperature in step S2 is 100°C and the rotation speed is 150rpm; the temperature in step S2 is 180°C and the rotation speed is 40rpm; the temperature in step S4 is 190°C and the pressure is 12MPa.

Embodiment 3

[0040] The difference from Example 1 is that the temperature in step S2 is 110° C. and the rotation speed is 180 rpm; the temperature in step S2 is 200° C. and the rotation speed is 50 rpm; the temperature in step S4 is 200° C. and the pressure is 15 MPa.

Abstract

The invention provides a preparation method of wear-resistant wood / plastic material, falling into the technical field of material processing. The material comprises the following materials by weight: 40-50 parts of plant fiber, 2-3 parts of carbon fiber, 5-10 parts of glass fiber, 5-10 parts of ceramic fiber, 1-5 parts of polyacrylonitrile-based carbon fiber, 3-5 parts of aluminum silicate fiber, 5-10 parts of cellulose, 10-15 parts of polystyrene, 10-15 parts of polypropylene, 5-8 parts of polyethylene, 2-6 parts of poly(butylene succinate), 10-15 parts of natural rubber, 10-15 parts of PVC resin, 5-8 parts of ethylene-acrylic acid copolymer, 1-2 parts of calcium carbonate, 2-3 parts of alumina, parts of silica 3-4, 1-3 parts of talc powder, 1-3 parts of diatomite, 1-2 parts of anhydrous magnesium chloride, 1-4 parts of magnesium sulfate, 2-3 parts of calcium stearate, 1-2 parts of a coupling agent, 1-2 parts of sodium phosphite, 2-3 parts of polyester wax and 4-8 parts of paraffin.

Description

technical field [0001] The invention provides a preparation method of a wood-plastic material, in particular relates to the preparation of a wear-resistant wood-plastic material, and belongs to the technical field of material processing. Background technique [0002] Wood-plastic materials are usually decorative materials obtained by adding PVC, PP, PE and other plastics, extruding and shaping raw materials such as wood trim and plant straw. It is suitable for wood processing methods such as drilling, planing, nailing, sawing, and laminating. It realizes "wood-plastic replacement of wood", protects limited forest resources, and reduces "white pollution". It is a national key promotion project. [0003] Wood-plastic materials can be used in packaging, gardening, transportation, construction, vehicle and ship interior decoration and other fields. [0004] Since the wood-plastic material contains a certain amount of plastic raw materials, this determines that the wood-plastic ...
