Description
Technical field
The invention belongs to field of high polymer material processing, and in particular to a kind of high-strength high flowing anti-impact wollastonite/polypropylene
Composite material and preparation method.
Background technology
For wollastonite as the maximum functional reinforced filling of current dosage in the world, being added to can be notable in polypropylene (PP)
Improve the performance indicators such as intensity, rigidity, heat resistance, Scratch Resistance of PP so that the use of wollastonite/PP composite materials gradually by
To the concern of people.Chinese patent CN102532692A, which is disclosed, a kind of to be improved it using acicular wollastonite filled polypropylene and anti-flies
The method of stone impact property is disadvantageous in that for this strongly hydrophilic material of wollastonite, not to wollastonite in the invention
It carries out surface to be modified to improve its hydrophobicity, so the mechanical property of wollastonite/PP composite material need the sky of progress
Between, the especially shock resistance of composite material.It is poly- that Chinese patent CN102875899A discloses a kind of wollastonite toughening enhancing
The preparation method of acrylic composite, but the mobility of final obtained composite material is poor in the invention, cannot meet mesh
Requirement of the preceding injection molding producer for large parts material high fluidity.
Invention content
The present invention provides a kind of wollastonite/PP composite materials, improve mobility, improve mechanical property.
Wollastonite/the PP composite material, in parts by weight, composition includes：
Wherein surface treatment wollastonite is obtained by following preparation method：By wollastonite, surface conditioning agent in mass ratio 100：
0.5~3 is added in powder surface modification equipment, and surface cladding processing is carried out to wollastonite；The surface conditioning agent is selected from
One or more of suberic acid, terephthalic acid (TPA), phthalic acid.
It is further preferred that in parts by weight, the wollastonite/PP composite material composition includes：
The wollastonite is coveredwith nanometer calcium carbonate wollastonite, draw ratio 10:1~20:1, preferably 12:1~16:
1.The length of draw ratio, that is, wollastonite and the ratio of diameter.
The wollastonite and surface conditioning agent mass ratio are preferably 100：1~2.
The powder surface modification equipment is CLG series powder surface modifiers.The temperature of surface cladding processing is 140
~150 DEG C, 10~15min of processing time.
The polypropylene be copolymer polypropylene, melt index >=60g/10min (230 DEG C, 2.16Kg), crystallinity >=
70%, isotacticity >=98%.Specifically, the polypropylene is selected from trade mark EA5076 or the China of PolyMirae companies of South Korea
The product of the trade mark M30V of petrochemical industry Yangtze petrochemical industry Co., Ltd.
The toughener is selected from ethylene-octene copolymer (POE), EPR ternary rubber (EPDM).
The lubricant is selected from one or more of polyethylene wax, solid paraffin, atoleine.
The preparation method of the wollastonite/PP composite material, including：
(1) wollastonite, surface conditioning agent are added in powder surface modification equipment, wollastonite is carried out at the cladding of surface
Reason, obtains surface treatment wollastonite；
(2) surface treatment wollastonite, polypropylene, toughener and mix lubricant are subjected to extruding pelletization.
Advantageous effect：
The present invention selects the wollastonite of coveredwith nanometer calcium carbonate, increases the specific surface area of wollastonite so that wollastonite table
Face has more active sites that can be reacted with modifying agent.
The present invention selects suberic acid, terephthalic acid (TPA), phthalic acid as surface modifier, with wollastonite surface or
Nano-calcium carbonate reaction generate calcium salt be effective polypropylene beta nucleating agent, can PP is enhanced using wollastonite it is same
When toughening effect is played to PP, improve the shock resistance of PP.
The suberic acid of the present invention, terephthalic acid (TPA), phthalic acid toxicity are smaller, small to the injury of staff.
Compared with the modified devices such as general high-speed mixer, the distinctive atomized spray of CLG series powder surface modifiers
Device can be mixed and modified in spray pattern progress by wollastonite powder and modifying agent, improves modification efficiency, shortens modification
Time, avoiding the powder present in high-speed mixer and modifying agent from mixing, uneven, incorporation time is long, silicon ash stone structure destroys sternly
The problems such as weight.
The present invention uses the PP of special parameter, can improve the mobility of final products.
