Abstract
The invention discloses a special injection grade wood-plastic material for pallets, which comprises the following components in percentage by weight percent: 20-45% of polypropylene reclaimed material, 51-70% of crop straw powder, 0.2-2.0% of lubricant, 3-15% of coating 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 additives. In the special injection grade wood-plastic material for the pallets of the invention, on the basis of superior comprehensive mechanical property and good processability, the percentage of the crop straw powder is far higher than 50%, the material of the invention can be quickly injected and produced into high-strength pallets by common injection grades, and the product has the characteristics of esthetic appearance, aging resistance and long service life.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to the special-purpose injection-grade wood moulding material of a kind of pallet.The invention still further relates to the method for making the special-purpose injection-grade wood moulding material of this pallet.
Background technology
The transportation of long trade at present is more and more, and number is huge.For saving loading and unloading strength, most of goods all are to pile up earlier on pallet, carried, loaded and unloaded by mechanical forklift again, thus, need a lot of pallets.Current pallet, a part are to use the plank bookbinding, need expend a large amount of timber like this, and need fumigate processing earlier when in export business, using, and could use then, so just waste time and energy, increase cost simultaneously, and so wooden pallet is often perishable, work-ing life is not long; Some is to use the acrylic plastering injection moulding to produce, and cost is very high, but the carrying out that can go to waste time and energy on the business of outward cargo fumigated processing, also has simultaneously and compares the longer advantage of wooden pallet work-ing life.
Wood-plastic material in the market is to adopt log wood powder or xylon and plastics compound mostly, the lumbering deforestation there is certain pushing effect, and, because the strength of materials and processibility are bad, only only limit to produce 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 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, the special-purpose injection-grade wood moulding material of pallet of the quick injection moulding production of the common injection grade of a kind of usefulness high strength pallet 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 special-purpose injection-grade wood-plastic preparation methods of pallet 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 the special-purpose injection-grade wood moulding material of pallet through screening and dewatering.
The special-purpose injection-grade wood moulding material of pallet of the present invention, on, the processibility good basis good at comprehensive mechanical performance, agricultural crop straw powder proportion is far above 50%, can be with the quick injection moulding production of common injection grade high strength pallet with material of the present invention, and product appearance is attractive in appearance, has ageing-resistant longer life feature, simultaneously with low cost, process easy, meet environmental protection, economic characteristics, harmless, can be when export business uses in order to avoid stifling, production procurement is easy to use, has improved competitive power.
Embodiment
Below be the most preferred embodiment of the special-purpose injection-grade wood moulding material of pallet of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, provides a kind of pallet special-purpose injection-grade wood moulding material, 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 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 injection-grade wood moulding material of pallet 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.
