Description
Technical field
The invention belongs to the Wood plastic composite technical field, relating to is a kind of Wood plastic composite and preparation method.
Background technology
Wood materials and steel, cement, plastics also are called four big basic raw materials, and wood materials is unique regenerated.The recoverable amount of China's big footpath level timber seldom at present; do not satisfy the demand in market; in order to solve this crisis; people advocate with steel on the one hand for wood, to mould Dai Mu; non-renewable oil and ore deposit iron resources have been consumed again; but caused the generation of one and another raw material crisis; on the other hand; in the face of tree is few greatly; people glue together use to the small wood small powder with the compound way; just must use a large amount of sizing materials, wherein 90% is urea-formaldehyde glue for this reason, and this is the main source that formaldehyde pollutes in the air.
Owing to lack the thin of a complete plastics recovery regeneration channel and environmental consciousness; also owing to lacking mature and reliable ground technology, the plastics that reclaim being fully utilized with the ground of method mass-producing cost-effectively; " white pollution " problem that plastic waste material causes has become a thorny difficult problem in the Chinese environmental protection cause; plastic working is as an industry, must consider the recycling problem after the institute's product of producing use.
Plastic-wood material arises at the historic moment thus, it is to reclaim plastics, agronomic crop fibre, " three surplus things " is raw material in the wood working, not only meets the performance requriements of Wood plastic composite, can be recycled simultaneously, improved the rate of recovery of plastics, having reduced plastics is the potential hazard of environment, has reduced manufacturing cost, improve to reclaim the added value of resource, utilize comprehensive utilization of resources and economize on resources.To protecting forest resources and ecotope, fully recycle resource and the important meaning of making a silk purse out of a sow's ear, can be used for industry or civilian goods such as pallet, building materials, great market capacity is arranged.
External at home, moulding wood development is extrusion moulding than product faster, is extruded quantitative limitation, and the product overwhelming majority is long-pending plate and a bar of leptoprosopy, and moulding wood simultaneously, to melt extrude system viscosity big, and expressing technique is poor, and the energy consumption height is difficult to form slick surface.As Chinese patent CN1786076A, open day is the preparation method who disclosed a kind of plastic-wood material on June 14th, 2006. the laminate structure mineral are pulverized, added coupling agent, make coupling laminate structure mineral powder; Wood powder is added coupling agent while stirring, make the coupling wood powder; With compound wood powder and the plastics that make, auxiliary agent is wanted to mix, and extrudes the wooden compound PP Pipe Compound of moulding promptly in forcing machine, and machine-shaping gets product; Chinese patent CN1912299A, open day is on February 14th, 2007, discloses a kind of plastic wood sheet and preparation method, it is combined into depleted plastics and agronomic crop fibre the novel material of a kind of green, environmental protection.The mechanical property of existing Wood plastic composite, heat-resisting, weathering resistance etc. wait to improve.At these problems, the Wood plastic composite that development research is new has application and vast market prospect widely.
Summary of the invention
In order to overcome above defective, the technical problem to be solved in the present invention is: propose a kind of Wood plastic composite and preparation method, it becomes a kind of matrix material with 100% advantage of recycling with the depleted plastics with refuse reason fiber composite, cheap, smooth finish is good, simultaneously good combination properties such as mechanical property, heat-resisting, weathering resistance.
