Description
(1) technical field
The invention belongs to technical field of composite materials, particularly a kind of environment protective plastic-wood composite material and preparation method thereof.
(2) background technology
Along with the sustainable development of China's modernization construction and the raising day by day of living standards of the people, people grow with each passing day to the demand of woodwork, and the supply of timber goes short of, and forest has been caused serious environmental problem by over-exploitation.At home,, promoted the production of plastic prod greatly, but its waste recovery utilizes system in time imperfect again, adds that people lack environmental consciousness, causes serious " white pollution " along with petroleum industry by leaps and bounds develops; On the other hand, China is a big coal country, is the basic fuel of electrical production with coal, and developing rapidly of power industry brought the rapid increase of flyash quantity discharged, and dust pollution is serious, is called as " black pollution ", and environment has been caused very big pressure.In the face of the misfortune source of these environmental pollutions, how to turn waste into wealth, turn harm into good, become important techniques economic policy in China's economic construction, be to solve China's environmental pollution, the important means of contradiction between the resource shortage.
Under this background, Wood plastic composite solves an effective way recycling waste wood and plastics just.Wood plastic composite (Wood-Plastics Composites, be called for short WPC) be compound by wood powder or xylon and thermoplastic polymer, the type material that forms by the melt-processed moulding with new structure and excellent over-all properties, its application is very extensive, relates to each field such as packing, transportation, gardening, house ornamentation.
The mildew-resistant of present Wood plastic composite product, anti-aging, wear resistant corrosion resistant is all not ideal enough, work-ing life is shorter; Because main the employing reclaimed waste material, and each storeroom bonding strength is not high, the physical and mechanical properties of product needs further to improve in addition.
(3) summary of the invention
The object of the present invention is to provide a kind of environment protective plastic-wood composite material and preparation method thereof, described Wood plastic composite mildew-resistant, anti-aging, wear-resisting, corrosion resistance and good, work-ing life is longer; The physical and mechanical properties of product is higher.
The technical solution used in the present invention is as follows:
A kind of environment protective plastic-wood composite material is made by the raw material of following weight parts: 100 parts of waste polyethylenes; Wood fiber powder 20-50 part; Flyash 5-30 part; Silane coupling agent 0.6-1.6 part; Treated carbonates 5-8 part; Irradiation sensitizing agent 0-4 part; Lubricant 4-8 part.
Described wood fiber powder is poplar powder or pine powder.
Described silane coupling agent is KH550, KH560 or KH570.
Described irradiation sensitizing agent is triallyl isocyanurate (TAIC) or Viscoat 295 (TMPTA).
Described lubricant is the mixture of talcum powder or stearic acid or two kinds, if two kinds are used simultaneously, then preferably according to talcum powder 4-6 part; Stearic acid 0.5-0.7 part is added.
Described waste polyethylene preferred molten index is the polyethylene of 0.1-10g/min.
Described environment protective plastic-wood composite material is preparation as follows preferably:
1) gets the raw materials ready:, handle and make that the wood fiber powder granularity is the 80-100 order, flyash 400-500 order the polyethylene extruding pelletization; Then wood fiber powder is dried to quality content and is not more than 3%;
2) mixed milling: silane coupling agent is mixed with wood fiber powder, flyash, add treated carbonates, lubricant and irradiation sensitizing agent then or do not add the irradiation sensitizing agent, thorough mixing evenly obtains composite sheet with polyethylene 140-160 ℃ of plasticizing then afterwards; Wherein during thorough mixing, can in high-speed mixer, carry out, stir 10-20min and get final product.
3) moulding: the composite sheet compression molding is obtained finished product sheet material, and pressure is 17-20MPa, and the time is 8-10min; Concrete, compression molding can be carried out in vulcanizing press;
4) irradiation: the finished product sheet material that obtains is placed on
60Normal temperature and pressure irradiation obtains described environment protective plastic-wood composite material under Co gamma-rays or the electron beam.
The exsiccant condition is at 90-100 ℃ of drying treatment 5-8h in the step 1).
The dosage of irradiation is advisable with 40-70kGy.
Wood plastic composite of the present invention is a main raw material with waste polyethylene, wood powder and flyash, makes jointly with irradiation sensitizing agent and other auxiliary agents.Its biggest advantage turns waste into wealth exactly and reuses, and greatly reduces production cost, and has saved a large amount of timber resources, has greatly promoted the competitiveness of product in market and profit margin; The adding of flyash has improved the mechanical property and the wear resisting property of Wood plastic composite preferably.Utilize simultaneously
60The irradiation of Co gamma-rays or electron beam realizes the formation of cross-linked network between polymer, and behind the polymer radiation crosslinking, its structure and performance generation respective change have improved the over-all properties of material; Can kill simultaneously mould corruption and fungi in the raw material wood powder effectively, solve the antimildew and antibacterial problem of Wood plastic composite well, widen its range of application; This technology has very big advantage to the deficiency that remedies current Wood plastic composite.
The flexural strength of the Wood plastic composite product of the present invention's preparation can reach 30-36MPa, modulus in flexure 1.7-2.3GPa, and tensile strength can reach 20-26MPa, and frictional coefficient is 0.175, shock strength 13-16kJ/m
2, water-intake rate only 0.5%, the requirement of the equal accord with Q of every performance index/HKT 004-2009.
The wear-resisting mildew-resistant of this product, environmental protection, surface smoothness is good.One of its main application is to substitute solid wood or plastics in each Application for Field, and wherein utilization is to substitute timber to do packaging boxboard, dalle and building template etc. the most widely.
The present invention has following advantage with respect to prior art:
This Wood plastic composite have with comprehensively utilization again of waste, environmental protection, energy-saving and emission-reduction, reusable, anticorrosion mildew-resistant, rain and sun, with low cost, be suitable for characteristics such as suitability for industrialized production, can save a large amount of timber resources, be beneficial to the protection environment.
