Description
Technical field
The invention belongs to technical field of polymer materials, relate to a kind of polymer blended material, relate in particular to a kind of modified ultra-high molecular weight polyethylene material.The present invention is applied to ultra wear-resisting environment, can guarantee higher draw tensile strength and elongation at break simultaneously.
Background technology
Ultrahigh molecular weight polyethylene(UHMWPE) is the very excellent thermoplastic engineering plastic of a kind of over-all properties.Because of having superpower wear resistance, excellent in impact resistance, lower temperature resistance and excellent self lubricity, it ideal application prospect is all arranged in a lot of fields.But the melting viscosity of ultrahigh molecular weight polyethylene(UHMWPE) is high, and huge molecular chain length causes intermolecular reactive force to be similar to the covalent linkage effect between the backbone c atoms, makes the processing temperature narrow range of material, occurs the situation of oxidative degradation easily.So to existing ultrahigh molecular weight polyethylene(UHMWPE) can only be to adopt intermittent type molding sintering moulding process; Produce simple bar and sheet material; Obtain end article through secondary mechanical processing again, thereby limited the actual industrial application of Vilaterm ultrahigh molecular weight polyethylene(UHMWPE).The researchist mainly addresses the problem of ultrahigh molecular weight polyethylene(UHMWPE) processing difficulties from two aspects at present, and the one, existing polymer processing machinery equipment is carried out modification, comprise the special length-to-diameter ratio of design, special screw-rod structure and technology; Be exactly on the other hand in the ultrahigh molecular weight polyethylene(UHMWPE) system, to sneak into specific material man-hour to improve its plasticizing capacity adding.The former is the supplementary means appearance with the latter, for example disclosed situation in " patent CN1284944C " and " patent CN1253501C " owing to reasons such as cost height are mostly.Major part is to adopt common polymer processing equipment that the ultrahigh molecular weight polyethylene(UHMWPE) of blending and modifying is processed, for example disclosed situation among " patent CN1156527C ", " patent CN1156528C ", " patent CN1070888C ", " the patent CN101235170B ".The superhigh molecular weight polyethylene material that obtains through above-mentioned processing units or method of modifying all has performances such as good wear-resisting, high breaking tenacity, but most elongation at break all can not surpass 400%, many times all be difficult to satisfy request for utilization.
Summary of the invention
The objective of the invention is to be directed against the technical problem that the elongation at break that has the modified ultra-high molecular weight polyethylene material now is difficult to satisfy request for utilization; Select for use POE that ultrahigh molecular weight polyethylene(UHMWPE) is carried out blending and modifying; And, a kind of modified ultra-high molecular weight polyethylene material of injection grade is provided through extruding pelletization.
In order to achieve the above object, the present invention addresses the above problem the technical scheme of being taked and is:
A kind of modified ultra-high molecular weight polyethylene material; By the quality percentage composition by component: ultrahigh molecular weight polyethylene(UHMWPE) is 60～70%; POE is 10～20%, and PP is 10～20%, and polyethylene wax is 1～8%; N-(β-aminoethyl)-γ-An Bingjisanjiayangjiguiwan is 1～2%, and antioxidant 1010 is 0.5～1% composition.
Wherein, described POE is the ethene that obtains through in-situ polymerization with metallocene catalyst and the thermoplastic elastomer of octene.
Above-mentioned modified ultra-high molecular weight polyethylene preparation methods: with ultrahigh molecular weight polyethylene(UHMWPE), POE, PP, polyethylene wax, N-(β-aminoethyl)-γ-An Bingjisanjiayangjiguiwan, that antioxidant 1010 is inserted high-speed mixer and mixing is even; Use common twin screw extruder that the said mixture material is carried out granulation then, one to seven district's temperature is respectively 160 ℃, 180 ℃, 195 ℃, 210 ℃, 220 ℃, 210 ℃, 200 ℃.
Modified ultra-high molecular weight polyethylene material of the present invention compared with prior art; Because wherein component POE is the ethene that obtains through in-situ polymerization with metallocene catalyst and the thermoplastic elastomer of octene; POE plastic molecules amount narrowly distributing; Have good mobility, good with compatible polyolefin property.The flexible chain coiled structure of octene and crystalline ethylene chain make the toughness of the existing excellence of the present invention that good processibility arranged again as the physical crosslinking point.The above-mentioned performance of POE provides theoretical basis for it to Modification of UHMWPE; The curling chain structure of the softness of octene can suitably weaken the reactive force between the ultrahigh molecular weight polyethylene(UHMWPE) molecular chain in the molecular structure in addition, thereby has further improved the workability of system.More crucial is, the modified ultra-high molecular weight polyethylene material that obtains through technical scheme of the present invention is chain structure because the softness of POE is curled, and in system, forms inierpeneirating network structure.Such interpenetrating(polymer)networks can form point of connection, between each composition, play connection, shock absorption, reduce crazing because of the stressed chance that develops into crackle, and the elongation at break of system is significantly increased.Sliding frictional wear amount >=13mg that material is final, tensile strength >=42Mpa, elongation at break >=550%.
