Abstract
The invention relates to a nanometer-coated wollastonite powder modified waste polyethylene composite material, which is prepared by stirring, melting, plasticizing and pelletizing raw materials such as waste polyethylene, nanometer-coated wollastonite powder, ground calcium carbonate, polyethylene wax, carbon black, a silane coupling agent and the like. The waste polyethylene composite material has the characteristics of ageing resistance, corrosion resistance, excellent electrical performance, high mechanical strength and the like, and is mainly used for special materials such as power cable sheath pipes and the like.
Description
Technical field
The present invention relates to a kind of modified waste composite polyethylene material, particularly a kind of employing nanometer coats the powder-modified waste polyethylene matrix material of wollastonite.
Background technology
Present known modified waste composite polyethylene material adopts the nano inorganic powder of surface-treated that waste polyethylene is carried out enhancing modified usually.As: surface-treated nano-calcium carbonate enhancing modified waste polyethylene.But the nano inorganic powder of surface-treated produces agglomeration through regular meeting in the actual course of processing, influence the physical and mechanical property of product.
Summary of the invention
The objective of the invention is to propose the excellent nanometer of a kind of physical and mechanical property and coat the powder-modified waste polyethylene matrix material of wollastonite.
The technical scheme that the present invention adopted is: adopt micron-class superfine wollastonite particle surface coated nano calcium carbonate to process nanometer and coat the wollastonite powder; Make the wollastonite particle be able to passivation, strengthen intermiscibility with waste polyethylene because of pulverizing the sharp corners that forms; Coat raw materials such as wollastonite powder, water-ground limestone, polyethylene wax, carbon black, silane coupling agent, form with waste polyethylene, nanometer by prescription through stirring, melting plasticizing, granulation process manufacturing.Adopting silane coupling agent in the raw material is that the water-ground limestone surface is handled, and makes water-ground limestone form consistency preferably with waste polyethylene; Adding carbon black is in order to improve electrical performance indexes.
Composition of raw materials of the present invention is:
| Title material | Weight ratio (part) |
| Waste polyethylene | 63-77 |
| Nanometer coats the wollastonite powder | 1.5-2.5 |
| Carbon black | 2.5-3 |
| Polyethylene wax | 3-5 |
| Silane coupling agent | 1-1.5 |
| Water-ground limestone | 15-25 |
The present invention utilizes heterogeneous nucleation crystallization deposition principle; At micron silicon lime stone powder particle surface depositing nano structure crystal, modify micron silicon lime stone granule-morphology, form the matrix material of concrete " examining a shell " structure; Improve filler and basal body interface associativity in the matrix material; Improve performance of composites, have anti-aging, corrosion-resistant, characteristics such as electrical property is good, physical strength height, be mainly used in power cable protecting pipe PP Pipe Compound etc.
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is production process route figure of the present invention.
Specific embodiments
According to shown in Figure 1, a kind of technical scheme of the present invention is: process nanometer with micron-class superfine wollastonite particle surface coated nano calcium carbonate and coat the wollastonite powder; By weight coat wollastonite powder, 25% water-ground limestone, 4% polyethylene wax, 3% carbon black, 1% silane coupling agent with 65% waste polyethylene, 2% nanometer, through stirrings, melting plasticizing, granulation process manufacturing granulating.
