Preparation method of degradable anti-pollution wood plastic material and product

Abstract

The invention discloses a preparation method of a degradable anti-pollution wood plastic material. The preparation method comprises the following steps: 1) preparing the components in parts by weight: 100 parts of PP / PE powder, 30-40 parts of (150-200)-mesh wood flour, 20-30 parts of modified starch, 10-15 parts of glass fibers, 5-8 parts of (900-1100)-mesh filler, 10-15 parts of nano SiO2 powder, 6-10 parts of toughening compatible coupling agent, 4-5 parts of PA-02 lubricative dispersing compatible coupling agent and 6-8 parts of anti-pollution agent; and 2) highly mixing the PP / PE powder, the (150-200)-mesh wood flour, the modified starch, the glass fibers, the (900-1100)-mesh filler and the nano SiO2 powder to 100-120 DEG C; after fully mixing, adding the PA-02 lubricative dispersing compatible coupling agent, the toughening compatible coupling agent and the anti-pollution agent and mixing to 120-140 DEG C; and after fully mixing, cooling to 30-50 DEG C and granulating to form the degradable anti-pollution wood plastic material. The mechanical properties of the material disclosed by the invention are adjusted by virtue of proportion of the glass fibers and the filler, the degradable environment-friendliness is adjusted by virtue of proportion of the plastic, the modified starch and the wood flour, and finally, the anti-pollution performance is enhanced by virtue of the nanoscale silicon dioxide and anti-pollution agent.

Description

technical field [0001] The invention relates to the preparation of wood-plastic materials, in particular to a preparation method and products of degradable anti-fouling wood-plastic materials. Background technique [0002] At present, wood-plastic material technology has reached a certain degree of maturity and has been widely used in daily life, such as floors, stair handrails, ventilated windows, micro-foamed cabinet boards, wave boards, and it also has a certain role in furniture. Applications. However, furniture is a large product, which requires wood-plastic materials to have high mechanical properties. Although the current wood-plastic materials have improved their mechanical properties by adding glass fibers, reinforcing agents, etc., it is still difficult to meet the demand. Because when it is used in furniture manufacturing, it often needs to be used together with wood, and the wood and wood-plastic are forcibly combined by external pressure or glue to achieve goo...

AI Technical Summary

Problems solved by technology

Although the current wood-plastic materials have improved their mechanical properties by adding glass fibers and reinforcing agents, it is still difficult to meet the needs.

Because when it is used in furniture manufacturing, it often needs to be used together with wood, and the wood and wood-plastic are forcibly combined by external pressure or glue to achieve good physical and mechanical properties, large bearing capacity, not easy to deform, and long service life. Long, if the mechanical properties of wood-plastic can not meet the requirements, it will affect the overall quality of furniture

In addition, the environmental performance of the current wood-plastic materials needs to be further optimized

Finally, the current wood-plastic materials have basically no improvement in the hydrophobic and oleophobic properties, and the defects of poor hydrophobic and oleophobic properties are fatal to furniture products. Water stains, oil stains, stains, etc. adhere to the furniture. , the first affects the appearance, the second is easy to attract parasites, leading to moths and fungi, and the third is easy to corrode the furniture, resulting in shortened life of the furniture
