Abstract
The invention discloses a special wood plastic composite (WPC) for extruding high-strength floor boards, which comprises the following compositions in percentage by weight: 20 to 45 percent of polypropylene recycling materials, 51 to 70 percent of crop straw powder, 0.2 to 2.0 percent of lubricants, 3 to 15 percent of coating agent, 1.0 to 8.0 percent of coupling agent, 1.0 to 5.0 percent of hydrotropic agent, 0.5 to 2.0 percent of anti-aging agent, and 0.1 to 5.5 percent of other additives. In the invention, based on excellent comprehensive mechanical property and good processability, the crop straw powder accounts for more than 50 percent; the special wood plastic composite of the invention can be used for quickly extruding high-intensity floor boards, and the high-intensity floor board has natural wood flavors, can be performed color matching as required, and meets the characteristics of environmental protection and economy, and has the advantages of beautiful appearance, high strength, low cost, simple processing, no harm to human, and convenient production and purchasing, thereby improving the competitiveness of the high-intensity floor board.
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 in high strength floor of extruding.The invention still further relates to this method of extruding the special-purpose Wood-plastic material in high strength floor of making.
Background technology
Wood-plastic material in the market is wood powder or xylon and the plastics compound that adopts log mostly, 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 simple relatively, intensity is not high, the processing charges that causes owing to processibility is bad again is high simultaneously looks forward to, thereby has to reduce as possible material cost, having 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 when improving people's quality of life profit level, also be huge to the meaning of environment protection.
Summary of the invention
The objective of the invention is to, provide a kind of can extrude production high strength floor board fast and product appearance attractive in appearance, have the natural breath of timber, intensity height, can match colors on request extrude the special-purpose Wood-plastic material in high strength floor,
In order to realize above-mentioned goal of the invention, technical scheme provided by the invention is as follows: it forms polypropylene reclaiming material: 20-45%, agricultural crop straw powder: 51-70% by weight by following composition; 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 who extrudes the special-purpose Wood-plastic material in high strength floor of the present invention, comprise the steps: earlier with polypropylene, 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 through screening and dewatering and to extrude the special-purpose Wood-plastic material in high strength floor.
The present invention extrudes that the special-purpose Wood-plastic material in high strength floor is good at comprehensive mechanical performance, on the processibility good basis, agricultural crop straw powder proportion can be extruded production high strength floor board far above 50% fast with material of the present invention, and product appearance is attractive in appearance, have the natural breath of timber, the intensity height can be matched colors on request, simultaneously with low cost, process easyly, meet environmental protection, economic characteristics, harmless, production procurement is convenient, has improved competitive power.
Embodiment
Below be the most preferred embodiment of extruding the special-purpose Wood-plastic material in high strength floor 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 in high strength floor of extruding is provided, and forms polypropylene reclaiming material: 27.5% by weight by following composition; 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%, wherein, the adding by these reagent makes that the Wood-plastic material that the present invention produced is good at comprehensive mechanical performance, on the processibility good basis, can extrude production high strength floor board fast.
Concrete steps of the present invention are as follows: earlier with polypropylene, 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 through screening and dewatering and extrude the special-purpose Wood-plastic material in high strength floor.
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.
