Abstract
The invention discloses a method for preparing a wood-plastic composite material from ultra-high molecular weight polyethylene composite material waste. The method comprises the following steps: directly pulverizing ultra-high molecular weight polyethylene fiber-reinforced composite material waste into particles with the particle size of 100-300 mu m or so, mixing the particles with wood meal, adding a coupling agent, sufficiently stirring and uniformly mixing; and adding the mixed particles into a mold, and carrying out hot pressing in a vulcanizer to obtain the wood-plastic composite material. The method does not need to separate the ultra-high molecular weight polyethylene fibers from the resin, and is simple and convenient in the recovery process; and the recovered wood-plastic composite material has higher toughness and lower price than the common polyethylene/wood meal composite material.
Description
Technical field
The present invention relates to a kind of method of utilizing ultra-high molecular weight polyethylene composite material waste material to prepare wood plastic composite, belong to ultra-high molecular weight polyethylene composite material recovery and utilization technology field.
Background technology
In recent years, different forms of violence terrorist incident constantly occurs both at home and abroad, increasing for the demand of protection class equipment on market, domestic each enterprise that produces protection class equipment all opened enough horsepower, produce protective gear with all strength, and in protection class equipment, ultrahigh molecular weight polyethylene(UHMWPE), due to its excellent protection function, has become and has carried out starting material mainly.Along with the raising of output, a large amount of ultrahigh molecular weight polyethylene(UHMWPE) scrap stock are produced in process of production.These scrap stock be recycled into a great problem.
At present, the research of wood plastic composite mainly concentrates on recycled plastic aspect both at home and abroad.Wherein taking polyethylene, polypropylene, polyvinyl chloride as main study subject.Ashori and for Nourbakhsh Recycled HDPE, PP and old newspaper fiber add maleic anhydride polypropylene to make wood plastic composite, by measuring its tensile strength, flexural strength, internal bond strength and water absorbing properties, find compared with reclaiming PP, reclaim PE and be more suitable for for the manufacture of wood plastic composite.The people such as Adhikary find by test, and the wood plastic composite performance of utilizing Recycled HDPE to make to new HDPE is similar, use Recycled HDPE even better.The people such as Wang Zheng utilize 3 kinds of recycled plastics such as PS, PE and PP and lumber fibre to prepare matrix material, and by the research of this matrix material physical and mechanical property being found in these 3 kinds of recycled plastics, PS plastics performance is best, PP plastics take second place, and PE plastics are the poorest.
Can find out both at home and abroad and also not occur as the research of wood plastic composite filler for reclaiming UHMWPE (ultrahigh molecular weight polyethylene(UHMWPE)) at present.
Summary of the invention
The technical problem to be solved in the present invention is that ultrahigh molecular weight polyethylene(UHMWPE) scrap stock are recycled.
In order to solve the problems of the technologies described above, technical scheme of the present invention has been to provide a kind of method of utilizing ultra-high molecular weight polyethylene composite material waste material to prepare wood plastic composite, it is characterized in that, step is:
The first step, the ultrahigh molecular weight polyethylene(UHMWPE) scrap stock that recovery is obtained are directly ground into the particle of certain particle diameter, after being mixed with particle, wood powder adds coupling agent, after stirring, make mixture, in mixture, the mass percent of wood powder is 40 ± 5%, the mass percent of coupling agent is 4 ± 0.5%, and surplus is particle;
Second step, mixture is put into hot pressing die, hot-forming on vulcanizer, hot pressing temperature is 175 ± 5 DEG C, hot pressing time is 8 ± 2min, and pressure is 10 ± 0.5MPa, in hot pressing, mould is vacuumized, make mixture realize hot pressing under vacuum condition.
Preferably, in the described the first step, described wood powder first makes its water ratio maintain 1 ± 0.5% through drying treatment.
The particle diameter of the particle that preferably, described ultrahigh molecular weight polyethylene(UHMWPE) scrap stock obtain after directly pulverizing is 100-300 μ m; The particle diameter of described wood powder is 20-100 order.
Preferably, described coupling agent is maleic anhydride grafted polyethylene.
Preferably, in described second step, described hot pressing die is the aluminium-making mould that applies releasing agent, and this aluminium-making mould has the adjustable pressing plate of thickness and vacuum orifice.
Innovation of the present invention is, be used for making wood plastic composite using the ultrahigh molecular weight polyethylene(UHMWPE) of recovery as filler, gained wood plastic composite, because the existence of ultrahigh molecular weight polyethylene(UHMWPE) has very excellent toughness, can be used for the fields such as indoor and outdoor decoration and replaces traditional timber.There is the feature cheap, mechanical property is outstanding compared with normal wood plastic composite materials.
Therefore, the present invention has following beneficial effect: the invention provides a kind of method of utilizing ultra-high molecular weight polyethylene composite material waste material to prepare wood plastic composite, the method is easy and simple to handle, cost recovery is low.Without separated fiber and resin.The wood plastic composite making has very important environment protection significance, can effectively replace timber, and has better toughness compared with common polythene wood plastic composite.
Embodiment
