Description
Technical field
The invention belongs to high molecular polymer field, and in particular to a kind of wood plastic composite special molding agent.
Background technology
Wood plastic composite is the class advanced composite material (ACM) being surging forward in recent years both at home and abroad, refers to and utilizes polyethylene, poly- third
Alkene and polyvinyl chloride etc., it is fine with the useless plant such as the wood powder more than more than 50%, rice husk, stalk instead of common resin adhesive
Dimension is mixed into new wood materials, then through plastic processings such as extruding, molding, injection mouldings, the sheet material or section bar produced.
It is mainly used in the industries such as building materials, furniture, logistics packaging.Through hot extrusion molding after plastics and wooden powder are mixed by a certain percentage
Sheet material, referred to as extrude wood-plastic composite panel.
Wood plastic composite has the advantages that incomparable, the base of wood plastic composite compared with traditional wood materials
Plinth is high density polyethylene (HDPE) and wood fibre, determines that its own has some characteristics of plastics and timber.Add with good
Work performance, wood plastic composite includes plastics and fiber, therefore, with the processing characteristics that same timber is similar, can saw, can follow closely,
It can dig, can be completed using carpenter's utensil, and nail-holding ability is substantially better than other synthetic materials.Mechanical performance is better than wood materials.
Nail-holding ability is usually 3 times of timber, is 5 times of particieboard.With good strength character, wood plastic composite includes plastics,
Thus with preferable modulus of elasticity.Further, since including fiber and through being sufficiently mixed with plastics, thus with suitable with hardwood
Resistance to compression, the physical and mechanical properties such as counter-bending, and its durability is substantially better than common wood materials.Case hardness is high, typically
It is 2-5 times of timber.With water-fast, corrosion resistant performance, service life is long, and Wood-plastic material and products thereof can resist strong compared with timber
It is soda acid, water-fast, corrosion-resistant, and not bacterial growth, it is difficult to be damaged by worms, not long fungi.Service life was long, up to more than 50 years.
With excellent adjustable energy, by auxiliary agent, plastics, which can polymerize, foam, solidifying, being modified, etc. changes, so as to change
The characteristics such as density, the intensity of Wood-plastic material, may also reach up the particular/special requirement such as anti-aging, antistatic, fire-retardant.With ultraviolet
Stability, coloring are good.Extensively, the plastic raw materials of production wood plastic composite are mainly high density polyethylene (HDPE) to its raw material sources
Or polypropylene, wood fibre can be wood powder, cavings or wood-fibred, further need exist for a small amount of additive and other processing aids.
But wood plastic composite also has its unavoidable shortcoming, is both, it must add chemical assistant or add
