Abstract
The invention discloses a wood-plastic composite and a making method of the wood-plastic composite. The wood-plastic composite comprises, by weight, 40-62% of wood meal, 30-45% of recycled PP/PE mixed plastics, 2-6% of compatilizer, 0.5-0.8% of antioxidant, 4-10% of fillers and 1-3% of lubricants. The wood-plastic composite can be normally produced through the recycled PP plastics and recycled PE plastics at any mixed ratio, the screening process for recycling the PP plastics and the PE plastics is omitted, and the recycling cost of raw materials is lowered.
Description
Technical field
The present invention relates to Wood-plastic material technical field, particularly relate to a kind of Wood-plastic material utilizing recovery PP/PE mixed plastic to make and preparation method thereof.

Preferably, described compatilizer is one or more mixing of maleic anhydride graft PP, maleic anhydride graft PE.
Preferably, described oxidation inhibitor is the mixing of antioxidant 1010, irgasfos 168.
Preferably, described weighting agent is calcium carbonate, one or more mixing talcous.
Preferably, described lubricant be polyethylene wax, maleic anhydride grafted polyethylene wax, chlorinatedpolyethylene one or more with stearic acid, one or more mix of Zinic stearas, calcium stearate.
A preparation method for Wood-plastic material, described preparation method comprises the steps:
A, will reclaim PP/PE mixed plastic, compatilizer, oxidation inhibitor, weighting agent, mix and blend is also heated to 90 DEG C, adds lubricant, and remix stirs and is heated to 110 DEG C;
After B, mix and blend terminate, mixed material is put cold mixed 5-10min to the cold mixed pot of high-speed mixer and remove aqueous vapor;
C, cooled mixture carry out granulation by tablets press, then by extruding production line, make the Wood-plastic profiles of different size according to difform mould.
As can be seen from the above technical solutions, the present invention has the following advantages:
Wood-plastic material provided by the invention, recovery PP plastics that arbitrary proportion can be used to mix and reclaim the normal production that PE plastics carry out Wood-plastic material, decrease reclaim PP plastics and PE plastics point choose process, reduce raw-material cost recovery.
