Abstract
The invention discloses a wood-plastic material and the technology thereof. The wood-plastic material is formed by the following components according to weight ratio: 5-30% of a polypropylene recycling and regenerating material, 51-70% of wood meal, 0.2-2.0% of a lubricant, 3-15% of a coating agent, 1.0-8.0% of a coupling agent, 1.0-5.0% of a wetting-out agent, 0.5-2.0% of an antiager, and 0.1-5.5% of other assistants. The wood-plastic material and the technology thereof, provided by the invention, are good in comprehensive mechanical property and processing property; as the proportion of crop straw powder is much higher than 50%, the material provided by the invention can be adopted to quickly extrude and produce a railway sleeper; the product is high in strength, all the advantages of a wooden sleeper are kept, the phenomenon of corrosion cannot be generated, the service life is relatively prolonged greatly, no lumber is required, the cost is low, the processing is easy and convenient, and the requirement of environment protection is met.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to a kind of Wood-plastic material and technique thereof.The invention still further relates to the method for making this Wood-plastic material and technique thereof.
Background technology
Railroad tie is pressed material properties classification: wooden crossties; Reinforced concrete sleeper; Steel sleeper; Composite material crosstie.Wherein, the feature of wooden crossties: good springiness, lightweight, make simply good insulation preformance.Fastener is connected with sleeper simply, and laying and maintenance, convenient transportation have larger frictional coefficient between sleeper and broken stone metaling.Sleeper is rich in tough erosion, more can absorb weight that train driving produces and easy fracture not than other sleepers.But its shortcoming is that working life is shorter, consumption amount of wood is large.Sleeper is easily rotten, the many impacts from insect pest, natural environment and climate of reason, and also with the passing of time railway spike hole on sleeper can relax because using, so general sleeper only has at most the life-span of more than ten years.For effectively increasing the service life, sleeper generally must use after oiling is anticorrosion.The sleeper now using, all passes through rotproofing, to stop insect pest and to extend working life.Also do not adopt in the market Wood-plastic material to produce sleeper.
Wood-plastic material is in the market to adopt the wood powder of log or xylon and plastics compound mostly, lumbering deforestation is had to certain pushing effect, and, due to the strength of materials and processibility bad, only only limit to extrude the product that some are relatively simple, intensity is not high, the processing charges causing because processibility is bad again high enterprise simultaneously, thus have to reduce as possible material cost, the route of having gone on the vicious cycle competition of inferior quality low price is huge to the damage of this industry.
The country having abroad, more than 50% wood plastic product that wood powder ratio accounts for overall proportion just can be as being that woodwork is sold society; Because wood powder and plastics are all refuse reclamations, so in improving people's quality of life and level, be also huge to the meaning of environment protection.
Summary of the invention
The object of the invention is to, a kind of wooden sleeper all advantages that keeps is provided, do not produce Wood-plastic material and the technique thereof of rotten phenomenon.
Technical scheme provided by the invention is as follows: it is made up of by weight following composition, polypropylene reclaiming material: 5-30%, polyethylene reclaiming material: 5-30%; Wood powder: 51-70%; Lubricant: 0.2-2.0%; Coating: 3-15%; Coupling agent: 1.0-8.0%; Moisture adsorbent: 1.0-5.0%; Anti-aging agent: 0.5-2.0%; Other auxiliary agents: 0.1-5.5%.
The preparation method of Wood-plastic material of the present invention and technique thereof, after comprising the steps: first polypropylene, polyethylene, wood powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally to be weighed in mixer low speed mixing 5 minutes, mixing extrusion, pelletizing in the screw combinations situation of shearing at some strength through twin screw extruder again, make Wood-plastic material and technique thereof through screening and dewatering.
Wood-plastic material of the present invention and technique thereof, good at comprehensive mechanical performance, on the good basis of processibility, crop stalk powder proportion is far above 50%, with material of the present invention extrusion railroad tie fast, and product strength is high, keep wooden sleeper all advantages, do not produce rotten phenomenon, be not afraid of from insect pest, the impact of natural environment and climate, do not worry the problem such as distortion due to immersion, relatively significantly extend work-ing life, do not consume timber simultaneously, simultaneously with low cost, process easy, meet environmental protection, economic characteristics, harmless, production procurement is convenient, improve competitive power.
Embodiment
Be below the most preferred embodiment of Wood-plastic material of the present invention and technique thereof, therefore do not limit protection scope of the present invention.
Embodiment mono-, provides a kind of Wood-plastic material and technique thereof, is made up of by weight polypropylene reclaiming material following composition: 14%, and polyethylene reclaiming material: 14%; Wood powder: 57%; Lubricant: 1.0%; Coating: 3.0%; Coupling agent: 5.0%; Moisture adsorbent: 2.5%; Anti-aging agent: 2.0%; Other auxiliary agents: 1.5%.
Concrete steps of the present invention are: after first will be first polypropylene, polyethylene, wood powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally being weighed in mixer low speed mixing 5 minutes, mixer adopts low speed mixing, paddle should be less than 0.5 centimetre with barrel gap, supplementary material mixed effect should visual various particles and powder substantially even, there is no obvious agglomerate or gather; Twin screw extruder uses 32 length-to-diameter ratios, and the combination of prescribed strength shear screw, arranges certain rotating speed; Adopt die face ring cutting mode, make Wood-plastic material and technique thereof through screening and dewatering.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
