Abstract
The invention discloses a special wood-plastic material for extrusion plates for replacing solid wood plates, which comprises the following compositions in percentage by weight: 20 to 45 percent of polypropylene reworked materials, 51 to 70 percent of crop straw powder, 0.2 to 2.0 percent of lubricants, 3 to 15 percent of packing agent, 1.0 to 8.0 percent of coupling agent, 1.0 to 5.0 percent of hygroscopic agent, 0.5 to 2.0 percent of anti-aging agent and 0.1 to 5.5 other additives. The invention can be used for solving the problems of machinability and intensity of materials, and the wood-plastic material of the invention can be used for producing high-intensity floor boards in various specifications by extruding, the produced high-intensity floor board has a beautiful appearance (extremely like the appearance of wood) and natural wood flavors, the intensity of the produced floor board is far more than that of general solid wood plates, and the produced high-intensity floor board can be cut and processed optionally according to the requirements of woodworkers without worrying about the problems such as deformation and the like caused by soaking, thereby greatly extending the service time relatively and reducing the cost.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to a kind of special-purpose Wood-plastic material of extrusion board of alternative solid wood board.The invention still further relates to the special-purpose Wood-plastic material method of the extrusion board 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 the 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,, only only limit to extrude the product that some are simple relatively, intensity is not high because the strength of materials and processibility are bad, simultaneously again because the high enterprise of the bad processing charges that causes of processibility, 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 are refuse reclamation all, so in raising people's quality of life and level, also be huge to the meaning of environment protection.
Summary of the invention
The objective 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: form polypropene recycled materials by weight by following composition: 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: earlier 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, again through twin screw extruder mixingly under the screw combinations situation that certain intensity is sheared extrude, pelletizing, make the special-purpose Wood-plastic material of the extrusion board that substitutes solid wood board through screening and dewatering.
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%, can be used for extruding production high strength all size sheet material with material of the present invention, 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 soak, relatively significantly prolong work-ing life, simultaneously with low cost, process easyly, meet environmental protection, economic characteristics; Be used for substituting timber, have fine meaning, can relievedly be used for and the human place that directly contacts, be convenient to produce in batches, promote, harmless, production procurement is convenient, has improved competitive power.
Embodiment
Below be the most preferred embodiment 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 forms polypropene recycled materials by weight by following composition: 27.5%, and agricultural crop straw 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%.
Earlier will be earlier 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 even substantially, 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, promptly 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 thereto; 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.
