Description
Technical field
The invention belongs to building material technical field, particularly a kind of plastic-wood section is specifically related to the material of this plastic-wood section, also relates to its preparation method.
Background technology
Wood plastic composite (Wood-Plastic Composites, WPC) be a class advanced composite material that in recent years is surging forward both at home and abroad, refer to utilize polyethylene, polypropylene and polyvinyl chloride etc. and the new material that is mixed into above useless vegetable fibres such as the wood powder more than 50%, rice husk, stalks.The section bar that wood plastic composite is produced through plastic processings such as extruding, mold pressing, injection moldings is referred to as plastic-wood section, is mainly used in the industries such as building materials, furniture, logistics packaging.
The basis of the employed material of plastic-wood section---wood plastic composite is high density polyethylene(HDPE) and wood fibre, this material has determined that plastic-wood section has good processing characteristics, good strength property, water-fast, corrosion resistant performance, long service life, good capable of regulating performance has ultraviolet stability, these performances make plastic-wood section substitute solid wood, obtain using more and more widely in building trade.
But plastic-wood section is in outdoor long-time use, constantly stand friction, the spot of hard thing invasion and attack and Exposure to Sunlight, wind, drench with rain etc., inevitably can cause wearing and tearing, pollute and aging, shorten its work-ing life.
In order to address the above problem, it is metal sheet or the tinsel of 0.1～0.5mm by adhesive attachment a layer thickness on the surface of plastic-wood section that the dealer is arranged, to improve wear resistance, pollution resistance and the weathering resistance (Chinese utility model patent 200720057206.3 of plastic-wood section, metal-plastic composite section), but the plastic-wood section of this form is high cost not only, processed complex, metal material can't imitate color and the outward appearance of solid wood, and metal sheet or tinsel easily come off from core, result of use is undesirable, is difficult to widely apply.
