Abstract
The invention relates to a straw powder and polypropylene composite wood-plastic material for injection molding, which consists of the following components in percentage by weight: 20 to 45 percent of polypropylene, 50 to 70 percent of crop straw powder, 0.2 to 2.0 percent of lubricating agent, 3 to 15 percent of toughening agent, 1.0 to 8.0 percent of coupling agent, 1.0 to 5.0 percent of absorbent and 0.1 to 5.5 percent of other aids. The straw powder and polypropylene composite wood-plastic material for injection molding maintains good comprehensive mechanical properties, and the crop straw powder accounts for much more than 50 percent, the material can injection-mold products with complicated structures and large areas, and the products have the advantages of attractive appearance, natural wood smell, high strength, color mixing according to requirements, low cost, simple and convenient processing, accordance with low carbon and economy characteristics, small shrinkage, uniformity, convenient production and purchase, and high competitiveness.
Description
Technical field
The present invention relates to a kind of polymer composite, more particularly, relate to a kind of injection moulding straw powder and polypropylene compound Wood-plastic material.The invention still further relates to the method for this injection moulding made from straw powder and polypropylene compound Wood-plastic material.
Background technology
Wood-plastic material in the market is to adopt wood powder or xylon and plastics compound mostly, the lumbering deforestation there is certain pushing effect, and, because material flowability is bad, generally be not used in injection moulding, only only limit to extrude the product that some are simple in structure relatively, intensity is not high.
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.
The invention solves the problem of material flowability, solved material strength problem, simultaneously, agricultural crop straw powder proportion is far above 50%, with the goods that material of the present invention can the injection structure complexity, area is big, and product appearance is attractive in appearance, has the natural breath of timber, the intensity height, can match colors on request, simultaneously with low cost, process easyly, meet low-carbon (LC), economic characteristics.Be used for injection moulding and produce some shell classes, landscape ornamental class, daily necessities product, substituted for plastic material and timber have fine meaning, and material cost and tooling cost are all obviously cheap, save cost, can use common injection moulding machine and mould, be convenient to produce in batches, promote.
Summary of the invention
The objective of the invention is to, a kind of injection moulding straw powder and polypropylene compound Wood-plastic material are provided, on comprehensive mechanical performance kept good basis, agricultural crop straw powder proportion was far above 50%, with the goods that material of the present invention can the injection structure complexity, area is big, and product appearance is attractive in appearance, the intensity height can be matched colors on request, processes easy, meet low-carbon (LC), economic characteristics, shrinking percentage is little and even.
Technical scheme provided by the invention is as follows: polypropylene: 20-45%; Agricultural crop straw powder: 50-70%; Lubricant: 0.2-2.0%; Toughner: 3-15%; Coupling agent: 1.0-8.0%; Moisture adsorbent: 1.0-5.0%; Other auxiliary agents: 0.1-5.5%.
The injection moulding of the present invention preparation method of straw powder and polypropylene compound Wood-plastic material, comprise the steps: earlier with polypropylene, agricultural crop straw powder, lubricant, toughner, coupling agent, moisture adsorbent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, the slow speed of revolution is mixing under the screw combinations situation that certain intensity is sheared extrudes through twin screw extruder again, water ring or underwater cutpellet make injection moulding straw powder and polypropylene compound Wood-plastic material through screening and dewatering.
Injection moulding of the present invention keeps on the good basis at comprehensive mechanical performance with straw powder and polypropylene compound Wood-plastic material, and agricultural crop straw powder proportion is far above 50%, with the goods that material of the present invention can the injection structure complexity, area is big, and product appearance is attractive in appearance, has the natural breath of timber, the intensity height, can match colors on request, simultaneously with low cost, process easy, meet low-carbon (LC), economic characteristics, shrinking percentage is little and even, and production procurement is convenient, has improved competitive power.
Embodiment
Below be the most preferred embodiment of injection moulding of the present invention, therefore do not limit protection scope of the present invention with straw powder and polypropylene compound Wood-plastic material.
Embodiment one, provides a kind of injection moulding with straw powder and polypropylene compound Wood-plastic material, form by weight by following composition: polypropylene: 27.5%; Agricultural crop straw powder: 57%; Lubricant: 1.0%; Toughner: 5.0%; Coupling agent: 5.0%; Moisture adsorbent: 3.0%; Other auxiliary agents: 1.5%.
Earlier will be earlier with polypropylene, agricultural crop straw powder, lubricant, toughner, coupling agent, moisture adsorbent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 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 the underwater cutpellet mode, promptly make injection moulding straw powder and polypropylene compound Wood-plastic material 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.
