Abstract

The invention discloses a preparation method of a stain-resistant anti-aging wood-plastic material, which comprises the following steps: 1) preparing the following components in parts by weight: PP (polypropylene), wood meal, chlorinated polyethylene, calcium stearate, talcum powder, nano carbon black, maleic anhydride graft polypropylene and nano montmorillonite; 2) thoroughly mixing the PP powder, wood meal, talcum powder and maleic anhydride graft polypropylene, grinding to 30 mu m below, preheating to 100-120 DEG C, sequentially adding the nano montmorillonite, nano carbon black, chlorinated polyethylene and calcium stearate, compounding uniformly, putting in a hot-pressing mold die cavity, preheating at 150-200 DEG C, closing the mold, and carrying out compression molding; and 3) cooling the hot-pressed material, pulverizing, preheating, compounding, cooling, and finally, granulating with a granulator to form the stain-resistant anti-aging wood-plastic material. The invention also discloses a stain-resistant anti-aging wood-plastic material prepared by the method.

Description

technical field [0001] The invention relates to the preparation of wood-plastic materials, in particular to a preparation method and product of anti-pollution and anti-aging 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 long-term product, which requires wood-plastic materials to have high mechanical properties, and at the same time must be resistant to aging, and must also be required in terms of flame retardancy and antifouling. [0003] With the strengthening of people's awareness of environmental protection and the need to protect forest resources and reduce the use of new wood, the call for recycling low-cost waste wood and plastics has become a common concern in ...
