Abstract
The invention discloses a special wood-plastic composite for a board, which is composed of the following components by weight percentage: 20-45% of polypropylene reclaimed material, 51-70% of straw powder of crops, 0.2-2.0% of a lubricating agent, 3-15% of a coating agent, 1.0-8.0% of a coupling agent, 1.0-5.0% of a moisture absorbent, 0.5-2.0% of an anti-aging agent and 0.1-5.5% of other auxiliaries. The special wood-plastic composite for the board provided by the invention solves the problems of composite processing and strength, can be extruded for production of high-strength boards of various specifications, the product is attractive in appearance, looks like very much to wood in appearance, has the natural smell of wood and the strength much higher than that of a common solid wood board, and can be cut and processed at will as per woodworking requirements without causing problems of deformation and the like due to water immersion, the service life is relatively and greatly prolonged, and besides, the cost is low.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to the special Wood-plastic material of a kind of sheet material.The invention still further relates to the special Wood-plastic material method of this sheet material of making.
Background technology
Along with the development of social production level, people's life is also more and more exquisite, and building decoration and furniture are increasing to the usage quantity of timber; People are also more and more stronger for the consciousness of environment protection and the protection of trees simultaneously; But these two requirements have seemed into contradictory problems.Wood-plastic material can effectively address the above problem.
But, Wood-plastic material is in the market to adopt log wood powder or xylon and plastics compound mostly, on the contrary 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 high enterprise of processing charges simultaneously that cause because processibility is bad again, thereby having to reduce as possible material cost, gone on the route of 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 special Wood-plastic material of sheet material that has solved materials processing problem and strength problem is provided.
Technical scheme provided by the invention is as follows: be made up of by weight polypropene recycled materials following composition: 20-45%, crop stalk 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 the special Wood-plastic material of sheet material of the present invention, after comprising the steps: first polypropene recycled materials, crop stalk 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 the special Wood-plastic material of sheet material through screening and dewatering.
The special Wood-plastic material of sheet material of the present invention, the invention solves the problem of materials processing, solve material strength problem, simultaneously, crop stalk powder proportion is far above 50%, can be used for extrusion high strength all size sheet material with material of the present invention, product appearance is attractive in appearance, the utmost point is as timber outward appearance, there is the natural breath of timber, intensity is far above common solid wood board, also can arbitrarily require to carry out cutting processing according to carpenter simultaneously, do not worry the problem such as distortion due to immersion, relatively significantly extend work-ing life, simultaneously with low cost, process easy, meet environmental protection, economic characteristics, for substituting timber, there is fine meaning, can the relieved place for directly contact with the mankind, be convenient to batch production, popularization, harmless, production procurement conveniently, has improved competitive power.
Embodiment
Be below the most preferred embodiment of the special Wood-plastic material of sheet material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment mono-, provides a kind of sheet material special Wood-plastic material, is made up of by weight polypropene recycled materials following composition: 27.5%, and crop stalk powder: 57%; Lubricant: 1.0%; Coating: 3.0%; Coupling agent: 5.0%; Moisture adsorbent: 3.0%; Anti-aging agent: 2.0%; Other auxiliary agents: 1.5%.
After first will be first polypropene recycled materials, agricultural crop straw 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 the not rotating speed higher than 300 revs/min; Adopt die face ring cutting mode, make the special Wood-plastic material of sheet material 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.
