The present invention relates to an ethylene-alpha-olefin copolymer and a manufacturing method thereof, and applications of the ethylene-alpha-olefin copolymer in molding product manufacturing, wherein the ethylene-alpha-olefin copolymer exhibits balanced and excellent processability and mechanical properties compared with the ethylene-alpha-olefin copolymer in the prior art.
Description
Technical field
The present invention relates to a kind of ethylene copolymer.Specifically, the present invention relates to a kind of ethene-alpha-olefin copolymer, its manufacture method and the application in moulded products manufactures thereof.
Background technology
Polyolefine is the synthetic resins that output is maximum in the world, has boundless application market.Polyolefine mainly comprises the multipolymer of polyethylene (PE), polypropylene (PP) and the alpha-olefin such as ethene and propylene, 1-butylene, 1-hexene and 1-octene.
In general, polyolefine such as poly intensity depends on its molecular weight, and molecular weight is higher, and the intensity of material, elasticity and environmental stress cracking resistance are higher, but the higher poly processing characteristics of molecular weight can be deteriorated.For this reason it is known that, improve the balance that the molecular weight distribution of polymkeric substance can realize polymer rigid, toughness and processing characteristics three, namely in the polyvinyl resin that molecular weight is higher, increase to improve the component that the molecular weight of processing characteristics is lower, present bimodal distribution to make poly molecular weight.Double peak weight distributing polyethylene refers to that molecular weight distribution is the linear polyethylene of bimodal pattern and the blend of ethene-alpha-olefin copolymer, comprises lower molecular weight, low branched moiety and high molecular, highly-branched degree two portions.In bimodal polyethylene, high molecular weight moieties can give its good intensity, toughness and environmental stress cracking resistance (ESCR), and low molecular weight part can ensure the rigidity of polymkeric substance, provides lubrication to improve the processing characteristics of resin simultaneously.Because bimodal polyethylene makes Drawing abillity and use properties reach good balance, become the important directions of polyolefin synthetic resin high performance.Double-peak high-density polytene, make the more difficult film of original process for processing and tubing have the development of advancing by leaps and bounds, film becomes easy processing, and tensile strength is improved; Tubing also has breakthrough in processing characteristics and environmental stress cracking resistance.
Chinese patent 200810213620.8 discloses a kind of ethene-alpha-olefin copolymer.Because molecular weight distribution is narrow, this ethene-alpha-olefin copolymer can only for the manufacture of polyethylene crosslinking goods, and be not suitable for manufacturing rotomoulded articles and high performance pipe.And in the manufacture method of the ethene-alpha-olefin copolymer disclosed in this Chinese patent, the catalytic activity of polymerizing catalyst cannot be fully played, copolymerization effect also has the leeway of improving further.
Chinese patent 200810213619.5 discloses a kind of ultrahigh molecular weight polyethylene(UHMWPE).Because molecular weight is higher, the processing characteristics of this ultrahigh molecular weight polyethylene(UHMWPE) is poor, and can only be applied to the high abrasion goods such as extruding pipe material under sintering process mold pressing and low speed, range of application is less.
Therefore, current present situation is, still needs a kind of ethene-alpha-olefin copolymer, and it has the characteristics such as suitable molecular weight distribution and oligomer, and takes into account processing characteristics and mechanical property.Prior art also needs a kind of manufacture method of ethene-alpha-olefin copolymer, and it can make the catalytic activity of polymerizing catalyst more be fully played, and copolymerization effect is more remarkable.
