Abstract
The invention relates to a mouldproof antibacterial wood plastic composite, comprising the following components in percentage by weight: 20-45% of polypropylene, 50-70% of crop straw powder, 0.2-8.0% of compound mouldproof antibacterial agent, 0.2-2.0% of lubricating agent, 3-15% of toughening agent, 1.0-8.0% of coupling agent, 0.0-5.0% of moisture absorbing agent and 0.1-5.5% of other auxiliaries. According to the mouldproof antibacterial wood plastic composite provided by the invention, ratio of the crop straw powder is far higher than 50% under the condition that the comprehensive mechanical performances are well maintained, the mouldproof antibacterial wood plastic composite provided by the invention can be used for producing a product with complex structure and large area by virtue of injection moulding, has natural flavour of timber and high strength, can be coloured as required, is low in cost and simple and convenient to process, meets low-carbon requirement, also has mouldproof and antibacterial functions and is especially preponderant when applied to outdoor, damp and biological contact products.
Description
Technical field
The present invention relates to a kind of polymer composite, more particularly relate to a kind of mildew-proof antibacterial wood-plastic material manufacture craft.The invention still further relates to the method for making this mildew-proof antibacterial 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 relatively simple in structure, 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.
Summary of the invention
The object of the invention is to, the mildew-proof antibacterial wood-plastic material of a kind of injection moulding with straw powder and polypropylene composite materials is provided, on the good basis of comprehensive mechanical performance maintenance, crop stalk powder proportion is far above 50%.
Technical scheme provided by the invention is as follows: polypropylene: 20_45%; Crop stalk powder: 50_70%; Composite mildewproof antiseptic-germicide: 0.2-8.0%; 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 the mildew-proof antibacterial wood-plastic material of straw powder and polypropylene composite materials, comprise the steps: first with polypropylene, crop stalk powder, composite mildewproof antiseptic-germicide, lubricant, toughner, coupling agent, moisture adsorbent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, again through twin screw extruder slow speed of revolution mixing extrusion in the screw combinations situation that some strength is sheared, water ring or underwater cutpellet make the mildew-proof antibacterial wood-plastic material that straw powder and polypropylene composite materials are used in injection moulding through screening and dewatering.
Mildew-proof antibacterial wood-plastic material of the present invention, on the good basis of comprehensive mechanical performance maintenance, crop stalk powder proportion is far above 50%, with the goods that material of the present invention is can injection structure complicated, area is large, and product appearance is attractive in appearance, have the natural breath of timber, intensity is high, can match colors on request, simultaneously with low cost, process easyly, meet low-carbon (LC), economic characteristics, shrinking percentage is little and even, have simultaneously the antimildew and antibacterial function concurrently, be used for product outdoor, moist, the biological aspect and especially possess advantage, production procurement is convenient, has improved competitive power.
Embodiment
Below be the most preferred embodiment that the mildew-proof antibacterial wood-plastic material of straw powder and polypropylene composite materials is used in injection moulding of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and the mildew-proof antibacterial wood-plastic material of a kind of injection moulding with straw powder and polypropylene composite materials is provided, and is comprised of by weight following composition: polypropylene: 24.0%; Crop stalk powder: 57%; Composite mildewproof antiseptic-germicide: 3.5%; Lubricant: 1.0%; Toughner: 5.0%; Coupling agent: 5.0%; Moisture adsorbent: 3.0%; Other auxiliary agents: 1.5%.
First will be first with polypropylene, crop stalk powder, composite mildewproof antiseptic-germicide 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 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 the underwater cutpellet mode, namely make the mildew-proof antibacterial wood-plastic material that straw powder and polypropylene composite materials are used in injection moulding 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.
