Abstract
The invention discloses a strengthening and toughening polypropylene composite, which comprises, by weight, 35 to 94 parts of polypropylene, 0.5 to 5 parts of polyfunctional monomer, 5 to 60 parts of inorganic filler and 0.2 to 4 parts of polypropylene universal antioxidant and processing agent. A preparation method of the strengthening and toughening polypropylene composite includes: mixing all components evenly, adding the components in a screw extruder to perform melt mixing reaction, extruding and prilling to obtain the strengthening and toughening polypropylene composite. In-situ graft reaction occurs in a melt mixing process through double bond of the polyfunctional monomer and polypropylene, simultaneously C=O bond of the polyfunctional monomer and hydroxy on the surface of the filler form hydrogen bond, interfacial interaction between the filler and a matrix is enhanced, thereby achieving high performance of the polypropylene composite. The obtained polypropylene composite not only has good toughness and rigidity, but also can restrain degradation of the polypropylene.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of enhancing tenacity-increased profax mixture and preparation method thereof.
Background technology
Polypropylene is one of five large general-purpose plastics, in industrial sector widespread uses such as chemical industry, building, light industry, automobile, household electrical appliances, packings.But along with the development of industry, more and more higher to the requirement of material property, common polypropylene must pass through modification, gives its high-performance, can satisfy the demand.
By new working method and to polypropylene, carry out blending and modifying, can make polypropylene realize high performance.Elastomer blended by polypropylene and rubber-like, can effectively improve the toughness of material, but conventionally can make intensity, modulus and the thermotolerance etc. of material significantly decline.Adopt filler filled polypropylene, can obviously improve the rigidity, hardness, heat-drawn wire of material etc., but conventionally can cause that the toughness of material declines.It is mainly because the polarity between filler and polypropylene matrix differs greatly that filled polypropylene toughness of material declines, and a little less than interface binding power, causes, and in fact the interface of filler and polymkeric substance has formed a kind of defect in system.
At present, conventionally adopt the method for In Situ Compatibilization to improve the interfacial interaction between filler and polypropylene.
As Chinese patent 03126909.5 relates to reactive monomer modified nano calcium carbonate/polypropylene masterbatch and manufacture method thereof, the method is, after polypropylene, nano-calcium carbonate, reactive monomer (comprising maleic anhydride, acrylicacidandesters class, vinylbenzene) and other auxiliary agents are mixed under high-speed mixer, with twin screw extruder, to prepare.The method can make the mechanical property of nanon calcium carbonatefilled polypropylene material improve, and still, adds polar functional group grafts, the toughness of meeting loss material; And for example Chinese patent 98111718.X relates to a kind of interpolation polyfunctional monomer to increasing reaction of polypropylene mixture method, the method is that polypropylene, blend components, initiator and two key additive are evenly mixed by a certain percentage, in screw extrusion press, carry out melt blending reaction and extrude after and get final product.These methods be all and a kind of material or and matrix or and filler between there is chemical bond, thereby its raising degree to interface interphase interaction has certain limitation.
Summary of the invention
For solving above-mentioned the deficiencies in the prior art, primary and foremost purpose of the present invention is to provide a kind of enhancing tenacity-increased profax mixture, and this mixture not only has excellent toughness and rigidity, but also can suppress polyacrylic degraded.
Another object of the present invention is to provide the preparation method of above-mentioned enhancing tenacity-increased profax mixture.
The present invention is achieved through the following technical solutions:
An enhancing tenacity-increased profax mixture, is characterized in that, counts by weight, comprises following component:
Polypropylene: 35-94 part;
Polyfunctional monomer: 0.5-5 part;
Mineral filler: 5-60 part;
Polypropylene general oxidation inhibitor and processing aid: 0.2-4 part.
Described polypropylene PP comprises one or both the mixture in Co-polypropylene and homo-polypropylene, and its melting index scope is 0.1-100g/10min.
Described polyfunctional monomer comprises one or more the mixture in diacrylate and triacrylate.
Described diacrylate is selected from 2-methyl isophthalic acid, ammediol diacrylate, Diethylene Glycol dimethacrylate, ethylene glycol dimethacrylate, diethylene glycol diacrylate, phthalic acid tripropylene glycol diacrylate, PDDA, polyethyleneglycol diacrylate, ethoxylated neopentylglycol diacrylate, neopentylglycol diacrylate, 1, 4-butylene glycol diacrylate, 1, 6-hexanediyl ester, the mixture of one or more in propylene glycol diacrylate and tripropylene glycol diacrylate.
Described triacrylate is selected from one or more the mixture in trimethylolpropane trimethacrylate, pentaerythritol triacrylate, propoxylated glycerol triacrylate, propoxylation Viscoat 295, ethoxylated trimethylolpropane triacrylate and Viscoat 295.
The inorganic substance that described mineral filler contains hydroxyl for surface, are selected from one or more the mixture in talcum powder, mica, wollastonite, kaolin, aluminium hydroxide, magnesium hydroxide, carbon black and clay.
Described polypropylene general oxidation inhibitor is 1010 or 168; Described processing aid is Zinic stearas or calcium stearate.
A preparation method who strengthens tenacity-increased profax mixture, is characterized in that: comprise the following steps:
A, polypropylene, mineral filler, multifunctional monomer, polypropylene general oxidation inhibitor and processing aid are joined in mixing equipment by proportioning, mix;
B, said mixture material is melt extruded at 190-230 ℃ with processing units screw extrusion press, rotating speed is 50-400 rev/min;
C, extrudate be through water cooling, pelletizing, and tenacity-increased profax mixture is enhanced.
Compared with prior art, tool has the following advantages in the present invention:
1) the present invention is that two keys by polyfunctional monomer in the process of melt blending, situ-formed graft occur with polypropylene and react; The C=O key of polyfunctional monomer and the hydroxyl of filling surface form hydrogen bond simultaneously, have strengthened the interfacial interaction between filler and matrix, thereby have realized the high performance of polypropylene composite;
