Description
Technical field
The present invention relates to wood plastic composite, be widely used in fields such as outdoor scene, highway, building decoration.
Background technology
The wood-plastic products that existing market is common often adopts unitary plastic as matrix resin, though processing and drawing materials has conveniently often followed the defective of unmodified resin.As single with PE as resin, though better wilful, rigidity is not enough, is prone to creep, often causes fragility excessive, easy to crack to add again after a large amount of stopping composition are adjusted rigidity, and proportion is excessive.Single with PP as resin, though rigidity is strong, often submissive deficiency, machine-shaping difficulty, and product is prone to degradation with aging.
Summary of the invention
The present invention the technical problem that will just solve just provide a kind of Wood-plastic material that adopts the modification of multiple recovery plastic blend to make; This Wood-plastic material possesses superior mechanical property; Higher wear-resisting, bending resistance, anti-impact are applicable to building bearing more than general single resin Wood-plastic material.
The present invention adopts following technical scheme: adopt the Wood-plastic material of multiple recovery plastic blend modification, it is characterized in that being made up of following component, specifically composition and weight proportion umber are following:
Reclaim PE 15-25 and reclaim PP 3-15

Pigment 0-3 carbon black 0-1;
Said recovery PP is all or part of copolymerization PP.
Preferably, said recovery PE mainly adopts HDPE, is aided with a small amount of LDPE or/and LLDPE, and HDPE accounts for more than 80%.
Wood-plastic material of the present invention adopts the modification of multiple recovery plastic blend as matrix resin, when taking into account the consistency of various resins own, learns from other's strong points to offset one's weaknesses.For guaranteeing better machining property, use a part of PE (when selecting feed back, be mainly HDPE and cooperate a small amount of LDPE and LLDPE); For remedying the insufficient shortcoming of PE rigidity; Add part flowability feed back PP preferably, consider the consistency between PE and PP, selected PP must be all or part of copolymerization PP; Be equipped with an amount of EVA simultaneously, make to have toughening effect concurrently.For better increasing base-material rigidity, hardness, an amount of modified kaolin is introduced in the crystallization that improves resin, has flame retardant effect simultaneously concurrently.No matter be PE or PP, all belong to non-polar resin, for guarantee with the polarity wood powder between the interface combine, in resin, introduce maleic anhydride, the grafting of use reaction method.
The present invention also provides the production technique of above-mentioned Wood-plastic material, specifically comprises the steps:
1) will reclaim PE, recovery PP, recovery EVA fragmentation, dry, with maleic anhydride, PP modified kaolin mechanically mixing, high-temperature fusion blend again, granulation, cooling make component A again;
2) plant fiber powder, methyl-monosilane coupling agent, methyl-silicone oil mechanically mixing is even, make B component;
3) Zinic stearas, ethylene bis stearamide, oxidation inhibitor, uv-absorbing agent, pigment, carbon black and component A, B component mechanically mixing is even; High-temperature fusion, plasticizing granulation, cooling, fragmentation again moulded special-purpose forcing machine fusion, typing, cooling, cutting through wood again and promptly made Wood-plastic material.
Said step 1) and 3) prilling temperature is controlled at 150～180 ℃ in.
Said step 1) and 3) tablets press is selected flat two tablets press for use in.
Technology of the present invention is simply effective, and the Wood-plastic material that adopts this technology to make possesses superior mechanical property, and higher wear-resisting, bending resistance, anti-impact are applicable to the functional domain of building bearing more than general single resin Wood-plastic material.
