Problems solved by technology

[0002] Most of the wood-plastic materials currently on the market are compounded with wood powder or wood fiber and plastic, which has a certain role in promoting logging and deforestation, and because the material has poor fluidity, it is generally not used for injection molding, and is limited to extruding some relative structures. Simple, low-strength product

Embodiment 1

[0009] Embodiment 1 provides a mold-proof and anti-bacterial wood-plastic material composited with straw powder for injection molding and polypropylene, which is composed of the following components by weight ratio: polypropylene: 24.0%; crop straw powder: 57%; composite anti-mold and anti-bacteria Agent: 3.5%; lubricant: 1.0%; toughening agent: 5.0%; coupling agent: 5.0%; hygroscopic agent: 3.0%; other additives: 1.5%.

[0010] Firstly, the polypropylene, crop straw powder, compound anti-mildew and antibacterial agent lubricant, toughening agent, coupling agent, hygroscopic agent, and other auxiliary agents are weighed according to the proportion and then mixed in a mixer at a low speed for 10 minutes. The feeder adopts low-speed mixing, and the gap between the mixing blade and the cylinder wall should be less than 0.5 cm. The mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, and there is no o...

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 [0001] The invention relates to a polymer composite material, and more specifically relates to a manufacturing process of an anti-mildew and anti-bacterial wood-plastic material. The invention also relates to a method for making the mildew-proof and antibacterial wood-plastic material. Background technique [0002] Most of the wood-plastic materials currently on the market are compounded with wood powder or wood fiber and plastic, which has a certain role in promoting logging and deforestation. Due to the poor fluidity of the material, it is generally not used for injection molding, and is limited to extruding some relative structures. Simple, low-strength product. [0003] In some foreign countries, wood-plastic products whose proportion of wood powder accounts for more than 50% of the total proportion can be regarded as wood products and sold to the society. Contents of the invention [0004] The object of the present invention is to provide a mildew-p...
