Abstract
The invention discloses a polyvinyl wood-plastic composite material, which is prepared by mixing the following components: wood flour, high-density polyethylene, maleic anhydride-grafted polyethylene and an assistant. According to the wood-plastic composite material, the ratio of the wood flour to the high-density polyethylene to the maleic anhydride-grafted polyethylene is optimized; and the phenomenon that the wood-plastic composite material is easily corroded and damaged after long-term use is avoided on the basis of ensuring good mechanical properties of the wood-plastic composite material.
Description
Technical field
The present invention relates to wood plastic composite field, be specifically related to a kind of polyethylene based wood-plastic composite material.
Background technology
Wood plastic composite is to be composited by string and plastics, has the feature performance benefit of timber and plastics concurrently, is onePlant novel environment-friendly materials, its product is mainly used as the substitute of timber. Being surging forward in recent years of wood plastic compositeA kind of composite, primary raw material is agriculture and forestry organic waste material and waste or used plastics, therefore develops wood plastic composite for environmental protection and uselessThe comprehensive utilization of gurry is significant. At present, the base wood-plastic composite material of preparing as primary raw material taking wood powder and polyethyleneMainly that substitute as timber is for outdoor building and outdoor decoration, when for a long time for outdoor environment, because it contains woodFiber or plant fiber component, thus cause inevitably and various contact with moistures, the wood plastic composite after water suctionDurability greatly reduces.
Summary of the invention
The object of the invention is, provides a kind of mechanical mechanics property good, the wood plastic composite that durability is strong, institute of the present inventionThe technical scheme adopting is:
A kind of polyethylene based wood-plastic composite material, is characterized in that, is mixed by following compositions in weight percentage:
Wood powder 40-55 part
High density polyethylene (HDPE) 20-40 part
Maleic anhydride grafted polyethylene 5-15 part
Auxiliary agent 5-10 part.
A kind of polyethylene based wood-plastic composite material, is characterized in that, is mixed by following compositions in weight percentage:
Wood powder 45-50 part
High density polyethylene (HDPE) 25-35 part
Maleic anhydride grafted polyethylene 8-12 part
Auxiliary agent 3-8 part.
Further, described auxiliary agent comprises lubricant, antioxidant.
Further, described maleic anhydride grafted polyethylene percent grafting is at 0.6-0.8%.
The present invention with respect to the beneficial effect of prior art is: wood plastic composite of the present invention, optimize wood powder, and highly denseDegree polyethylene, maleic anhydride polyethylene three's proportioning, is ensureing the basis of wood plastic composite in good mechanical mechanical propertyUpper, avoid the long-term use of wood plastic composite easily to occur the phenomenon of corrosion failure.
