Description
Technical field
The invention belongs to macromolecule modified material production technical field, be specifically related to a kind of ultrahigh molecular weight polyethylene(UHMWPE) waterproof roll and preparation method thereof.
Background technology
Along with the fast development of economy, China Express Railway obtains and develops rapidly, and due to China's each department landform and geologic framework complexity, railway tunnel also gets more and more thereupon.In the maintenance of tunnel excavation and operation tunnel, waterproof and leakage problem are current common faults the most outstanding, are also comparatively one of stubborn problems in traffic engineering.The using function that tunnel leak not only greatly reduces various facility in tunnel closes the life-span, worsens the operation condition in tunnel, brings out traffic accident.On the other hand, bridge infiltration and leak and also greatly can reduce the work-ing life of bridge.
The Typical Representative of new type waterproof coiled material is main body with macromolecular material, and this represents the development trend of waterproof novel material, although start late in China, development is very fast, and to the future development of multi items, multiscale, tandem product.Novel high polymer waterproof roll mainly comprises Ethylene Propylene Terpolymer, polyvinyl chloride, chlorinatedpolyethylene, chlorinatedpolyethylene-waterproof roll such as blend rubber, polyethylene polypropylene.And use ultrahigh molecular weight polyethylene(UHMWPE) (being called for short UHMWPE) modification production waterproof roll to be a kind of waterproof novel material that recent years, new development was got up.
Ultrahigh molecular weight polyethylene(UHMWPE) typically refers to the linear polyethylene of relative molecular mass more than 1,500,000.The high molecular weight of UHMW-PE gives the use properties of its excellence, and belong to thermoplastic engineering plastic that is moderate, excellent property, it has almost concentrated the advantage of various plastics, there is the advantages such as common polythene and the unrivaled shock-resistance of other engineering plastics, corrosion-resistant, wear-resistant, self lubricity, nontoxicity and extremely excellent lower temperature resistance, due to the special performance that UHMWPE has, the particular requirement of many branchs of industry to material thus can be met.
The weight break point by becoming China's building and Road construction waterproof cause of UHMWPE water-proofing coiled material, and very important effect is played in building high-speed rail bridge Tunnel Engineering.Not only there is good water resistance, also have the performance of higher high temperature resistant, low temperature, to adapt to the temperature variation of usage period.Also have good intensity and unit elongation, and the features such as excellent ageing-resistant, elasticity will be had, to adapt to the change of basic unit, but also there is stronger permeability resistance, constructing operation is easy, speed is fast, is easy to the features such as grasp, interiorly in a big way can use filler, reduce cost.Therefore can be widely used in the seepage etc. in the roof waterproof of top-grade building thing, engineering waterproofing, subway engineering waterproof, high-speed rail bridge tunnel water proofing, tunnel roof waterproof, refuse tip, use range is wider.
The UHMW-PE of melting, from having during high temperature die extrusion certain " melting rigidity ", be not at once sagging, the solid state that is translucent level moves forward to partial below, shows as high viscoelastic state.It can thus be appreciated that, be that viscosity is high, the special melt of flowing extreme difference during UHMW-PE melting.UHMW-PE frictional coefficient is extremely low, even be also like this when molten state, therefore easily skid at feeding section in fill process, cannot push ahead, and this is also that Screw Extrusion adds another difficult problem run into man-hour.Mold temperature narrow range, oxidizable degraded.
