Embodiment 1

[0027] Taking the wood-plastic composite material as 100 parts, the specific preparation method is as follows:

[0028] (1) Mix the raw materials uniformly in a high-speed mixer at room temperature; the reinforcing filler can be activated by combining silane coupling agent, titanate coupling agent or aluminate coupling agent with the reinforcing filler Stir the filler together in a high-speed mixer for 5-10 minutes at high speed;

[0029] (2) Mix and extrude the mixture obtained in (1) in a co-rotating parallel twin-screw extruder to obtain a composite material compound;

[0030] (3) Add the compounded material into a conical twin-screw extruder for extrusion molding to obtain a composite material product.

[0031] The raw materials used in Example 1 and the mass parts of each raw material are shown in Table 1.

Abstract

An elastomer toughening wood-plastic composite material is composed of, by mass percentage, 15-30% of polyolefin resin, 40-70% of plant fiber powder, 0-30% of reinforcing filler, 1-5% of thermoplastic elastomers, 2-5% of compatilizer, and 0-2% of additives. According to the elastomer toughening wood-plastic composite material and a preparation method of the elastomer toughening wood-plastic composite material, the high fiber content, mechanical strength and rigidity of the wood-plastic composite material are kept, and meanwhile, toughness of the wood-plastic composite material is improved. The cracking and fractured rate of the wood-plastic composite material during the processing and using processes is lowered, and the service life of the wood-plastic composite material is prolonged.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a thermoplastic elastomer toughened polyolefin wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite materials are profiles, plates or other products made of polymer resin and plant fiber powder as the main raw materials through extrusion, injection, pressing and other molding methods at a certain temperature and pressure. Wood-plastic composite materials can be processed in a variety of ways like natural wood, and can be used in many fields such as furniture, construction, industry, packaging and transportation, and outdoor landscapes. They are ideal materials to replace natural wood. [0003] At present, in order to improve the wood-like characteristics of wood-plastic composite materials and reduce production costs, wood-plastic manufacturers often choose to increase the filling amount of...
