Abstract
The invention discloses a wood-plastic material replacing a solid wood plate. The wood-plastic material consists of the following components in percentage by weight: 20-45% of polypropylene reworked material, 51-70% of crop straw powder, 0.2-2.0% of lubricant, 3-15% of cladding agent, 1.0-8.0% of coupling agent, 1.0-5.0% of moisture absorbent, 0.5-2.0% of anti-aging agent and 0.1-5.5% of other auxiliaries. The extrusion plate special wood-plastic material replacing a solid wood plate disclosed by the invention solves the problems of material processability and material strength; the material can be applied to the extrusion production of various high-strength plates; the product has a beautiful appearance much like the wood appearance as well as the natural smell of wood, and the strength is much higher than that of a common solid wood plate; meanwhile, the wood-plastic material can be cut at will according to the woodwork requirements without the problems of deformation caused by water soaking and the like; and the service life is remarkably prolonged, and the cost is low.
Description
Technical field
The present invention and a kind of matrix material in particular, relate to a kind of Wood-plastic material of alternative solid wood board.The invention still further relates to the method for the Wood-plastic material of making this alternative solid wood board.
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 in the market is to adopt log wood powder or xylon and plastics compound mostly, on the contrary the lumbering deforestation there is certain pushing effect, and because the strength of materials and processibility are bad, only only limit to extrude the product that some are relatively simple, intensity is not high, simultaneously again because the bad processing charges that causes of processibility is high, 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 that has abroad; the wood plastic product more than 50% that the wood powder ratio accounts for overall proportion just can be as being that woodwork is sold society; because wood powder and plastics all are refuse reclamations, so in raising people's quality of life and level, also be huge to the meaning of environment protection.
Summary of the invention
The object of the invention is to, a kind of special-purpose Wood-plastic material of extrusion board that has solved the alternative solid wood board of materials processing problem and strength problem is provided.
Technical scheme provided by the invention is as follows: be made of polypropene recycled materials following weight ratio of constituents: 20-45%, agricultural crop straw 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-purpose Wood-plastic material of the extrusion board of alternative solid wood board of the present invention, comprise the steps: first with polypropene recycled materials, agricultural crop straw powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 5 minutes, through twin screw extruder mixing extrusion, pelletizing in the screw combinations situation that some strength is sheared, make the special-purpose Wood-plastic material of the extrusion board that substitutes solid wood board through screening and dewatering again.
The present invention substitutes the special-purpose Wood-plastic material of extrusion board of solid wood board, the invention solves the problem of materials processing, solved material strength problem, simultaneously, agricultural crop straw powder proportion is far above 50%, the material that is used for invention can be used for extrusion high strength all size sheet material, and product appearance is attractive in appearance, and the utmost point is as the timber outward appearance, has the natural breath of timber, intensity also can arbitrarily require to carry out cutting processing according to the carpenter far above common solid wood board simultaneously, does not worry the problems such as distortion owing to soaking, relatively significantly prolong work-ing life, simultaneously with low cost, process easyly, meet environmental protection, economic characteristics; Be used for to substitute timber, have fine meaning, can be relieved for the place that directly contact with the mankind, be convenient to batch production, popularization, harmless, production procurement has conveniently improved competitive power.
Embodiment
Below be the best case study on implementation of the special-purpose Wood-plastic material of extrusion board of alternative solid wood board of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of special-purpose Wood-plastic material of extrusion board of alternative solid wood board is provided, and is made of polypropene recycled materials following weight ratio of constituents: 20-45%, agricultural crop straw 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%.
First with polypropene recycled materials, agricultural crop straw powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 5 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 32 length-to-diameter ratios, the combination of prescribed strength shear screw, and setting is not higher than 300 rev/mins rotating speed; Adopt die face ring cutting mode, namely make the special-purpose Wood-plastic material of the extrusion board that substitutes solid wood board through screening and dewatering.
The above; it only is 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; variation or the replacement that can expect without creative work all should be encompassed within 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.
