Description
Technical field
The present invention relates to a kind of preparation method of Wood plastic composite, belong to short flow process composite material manufacturing technology technical field.
Background technology
Wood plastic composite is meant and adopts wood fibre and thermoplastics (contain and reclaim plastics), through the mixing new green environment protection material of being processed into, also claims wood plastic composite, natural-fiber composite material.
China's forest coverage is low, because overexploitation brings vegetation desertification and sandstorm day by day.Existing forest harvesting utilization ratio and timber are made a low multiple use, and have only the utilization again of strengthening existing resource, and the surrogate of exploitation timber just can better be contained the trend that the forest reserves fall sharply.To make full use of on the one hand " three surplus things " in the wood working: logging residue (branch etc.); Producing material residuum (producing material butt etc.); Industrial wood waste (sawdust, wood shavings etc.).To make full use of agronomic crop fibre on the other hand.In the rural area, a large amount of agronomic crop fibre (rice chaff, stalk etc.) is by burning disposal.Not only cause the serious waste of natural resources, and the harm environment.So must find the road of a pollution-free processing agricultural fibre.
Owing to lack the thin of a complete plastics recovery regeneration channel and environmental consciousness; also since lack mature and reliable technology, with cost-effective method mass-producing ground the plastics that reclaim are fully utilized, " 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 after the institute's product of producing use.
Wood plastic composite arises at the historic moment thus, it with reclaim in plastics, agronomic crop fibre, the wood working " three surplus things are raw material; not only meet the performance requriements of Wood plastic composite; can be recycled simultaneously; improved plastics the rate of recovery, reduce the potential hazard of plastics to environment; reduced manufacturing cost, improved the added value that reclaims resource.Help comprehensive utilization of resources and economize on resources.To protecting forest resources and ecotope, fully recycle salvage material, it is significant to make 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.
At present, existingly mould wooden compounding technology and have following problem: mould wood and melt extrude that system viscosity is big, poor, the energy consumption height of expressing technique, be difficult to form slick surface.The mechanical property of existing Wood plastic composite, heat-resisting, weathering resistance etc. wait to improve.We have developed laminate structure mineral powder and have coated the wood powder technology at these problems, have application and vast market prospect widely.
Summary of the invention
The objective of the invention is to propose a kind of preparation method of Wood plastic composite, change the preparation technology of existing Wood plastic composite, extrude system viscosity, improve expressing technique with reduction, thereby reduction production energy consumption, improve product glossiness, and improve mechanical property, weathering resistance and the thermotolerance of product.
The preparation method of the Wood plastic composite that the present invention proposes may further comprise the steps:
(1) the laminate structure mineral is crushed to 1000～3000 orders, under 90～110 ℃,, add the coupling agent that accounts for laminate structure mineral grain weight amount 0.5～5% while stirring with 1000～3000 rev/mins of violent stirring, high-speed stirring 10～30 minutes makes coupling laminate structure mineral powder;
(2) with 50～200 purpose wood powders under 90～110 ℃, with 1000～3000 rev/mins of violent stirring, add the coupling agent account for wood powder weight 0.5～5% while stirring, high-speed stirring 10～30 minutes makes the coupling wood powder;
(3) above-mentioned coupling wood powder and the ultra-fine laminate structure mineral of coupling powder are mixed the coupling wood powder mutually: the ultra-fine laminate structure mineral of coupling powder=100: 10～40 are that ball milling made compound wood powder in 0.5～5 hour in 40～800 rev/mins the ball mill at rotating speed;
(4) the above-mentioned compound wood powder that makes is mixed mutually with plastics, auxiliary agent, the weight percent of compound wood powder and plastics, auxiliary agent is: compound wood powder: plastics: auxiliary agent=1～1.5: 1: 0.15, extrude promptly to get in forcing machine and mould wooden compound PP Pipe Compound.PP Pipe Compound gets final product to such an extent that mould wooden composite product through certain mould extrusion moulding, injection or mold pressing.
Laminate structure mineral in the aforesaid method are talcum or illite.
Coupling agent in the aforesaid method is any in silane coupling agent, titanate coupling agent, aluminate coupling agent or the zirconium aluminate coupling agent or multiplely uses with any mixed.Silane coupling agent wherein is any among KH550, KH560 or the KH570.Titanate coupling agent wherein is any among NDZ102, NDZ201, NDZ210, NDZ331 or the NDZ401.Aluminate coupling agent wherein is any among DL-441-A, DL-481 or the DL-427.Zirconium aluminate coupling agent wherein is any among APG, CPG, MPG or the SPM.
Wood powder in the aforesaid method is any in wood working scrap stock powder, rice husk meal, straw powder, the shell powder.
Plastics in the aforesaid method are for reclaiming polyethylene, reclaim polypropylene, reclaiming any in the polyvinyl chloride.
Auxiliary agent in the aforesaid method is the mixture of chlorinatedpolyethylene, maleic anhydride and dicumyl peroxide, and its weight ratio is: chlorinatedpolyethylene: maleic anhydride: dicumyl peroxide=10～20: 2～6: 1.
The preparation method of the Wood plastic composite that the present invention proposes, by the mechanical force and chemical effect, ultra-fine laminate structure mineral powder is coated wood powder, obtain the wood powder of compoundization, extrude with recovery plastics melt blending then, by the lubrication of laminate structure mineral powder, reduce to extrude resistance, improve the rheological that melt extrudes mixture.Utilize the two-dimentional enhancement function of laminate structure mineral lamella simultaneously, work in coordination with the mechanics and the thermotolerance that improve Wood plastic composite, utilize the function of laminate structure mineral powder absorption UV-light, improve the ageing resistance of Wood plastic composite.The present invention compare with existing Wood plastic composite have that moulding processability is good, low (melting index improves 20%～50% to energy consumption in the time of 190 ℃, improve 40%～70% in the time of 200 ℃), surface flatness height, woodiness touch be strong, mechanical property height characteristics such as (improving 20%～50% as impact resistance).Can be widely used in building and ornament materials (man-made tourist site, railing, floor, square, bench), building template, railroad tie, industrial pallet etc.
