Abstract
The invention relates to a mouldproof antibacterial wood-plastic material which comprises the following components in percentage by weight: 20-45 percent of polypropylene, 50-70 percent of the crop straw powder, 0.2-8.0 percent of a compound mouldproof antibacterial agent, 0.2-2.0 percent of a lubricant, 3-15 percent of a flexibilizer, 1.0-8.0 percent of a coupling agent, 1.0-5.0 percent of a hygroscopic agent, and 0.1-5.5 percent of the other agents. According to the mouldproof antibacterial wood-plastic material, on the basis of maintaining good comprehensive mechanical performance, the proportion of the crop straw powder is far higher than 50 percent, the mouldproof antibacterial wood-plastic material can be used for manufacturing products with complex structures, and large areas through injection molding, has natural smell of wood, is high in strength, can be coated with different colors according demands, is low in cost, simple and convenient to process, meets the standard of low carbon, and meanwhile, has a mouldproof antibacterial function, and is particularly suitable for outdoor, humid, and biological contact products.
Description
Technical field
1, the present invention relates to a kind of polymer composite, more particularly, relate to a kind of mildew-proof antibacterial wood-plastic material.The invention still further relates to the method for making this mildew-proof antibacterial wood-plastic material.
Background technology
2, Wood-plastic material is in the market to adopt wood powder or xylon and plastics compound mostly, lumbering deforestation is had to 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.
3, the country having abroad, more than 50% wood plastic product that wood powder ratio accounts for overall proportion just can be as being that woodwork is sold society.
Summary of the invention
4, the object of the invention is to, a kind of mildew-proof antibacterial wood-plastic material is provided, on comprehensive mechanical performance keeps good basis, crop stalk powder proportion is far above 50%.
5, 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%.
6, the preparation method of mildew-proof antibacterial wood-plastic material of the present invention, after comprising the steps: first polypropylene, crop stalk powder, composite mildewproof antiseptic-germicide, lubricant, toughner, coupling agent, moisture adsorbent, other auxiliary agents proportionally to be weighed in mixer low speed mixing 10 minutes, slow speed of revolution mixing extrusion in the screw combinations situation of shearing at some strength through twin screw extruder again, water ring or underwater cutpellet, make mildew-proof antibacterial wood-plastic material through screening and dewatering.
7, mildew-proof antibacterial wood-plastic material of the present invention, on comprehensive mechanical performance keeps good basis, crop stalk powder proportion is far above 50%, with material of the present invention can injection structure complexity, the goods that area is large, and product appearance is attractive in appearance, there is the natural breath of timber, intensity is high, can match colors on request, simultaneously with low cost, process easy, meet low-carbon (LC), economic characteristics, shrinking percentage is little and even, have antimildew and antibacterial function concurrently simultaneously, for outdoor, moist, the product of biological aspect especially possesses advantage, production procurement is convenient, improve competitive power.
Embodiment
8, be below the most preferred embodiment of mildew-proof antibacterial wood-plastic material of the present invention, therefore do not limit protection scope of the present invention.
9, embodiment mono-, provides a kind of mildew-proof antibacterial wood-plastic material, is made up of by weight: polypropylene: 24.0% following composition; 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%.
10, after first will be first polypropylene, crop stalk powder, composite mildewproof antiseptic-germicide lubricant, toughner, coupling agent, moisture adsorbent, other auxiliary agents proportionally being weighed in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should be less than 0.5 centimetre with barrel gap, supplementary material mixed effect should visual various particles and powder substantially even, there is no obvious agglomerate or gather; Twin screw extruder uses 32 length-to-diameter ratios, and the combination of prescribed strength shear screw arranges the not rotating speed higher than 300 revs/min; Adopt underwater cutpellet mode, make mildew-proof antibacterial wood-plastic material through screening and dewatering.
11, the above; it is only 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; the variation that can expect without creative work or replacement, within all should being encompassed in 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.
