Abstract
The utility model discloses a novel high -impact PE pipe material, including inlayer and skin, the inlayer is white low pressure high density polyethylene layer, the skin is high -pressure low density polyethylene layer, there is one deck winding steel wire layer through integrative bonding of hot -melt adhesive layer between inlayer and the skin, winding steel wire layer includes the two -layer fashioned netted steel frame of left right spiral winding that is respectively, the utility model has the advantages of: not only having higher pressure resistance, having good shock resistance simultaneously again, intensity is high, long service life.
Description
Technical field
This utility model relates to a kind of plastic composite pipe, a kind of novel high impact polyethylene tubing, belongs to plastic composite pipe field.
Background technology
Polyethylene pipe becomes no-dig technique with the pliability of its excellence and lays the first-selection of pipeline without sand.There is the problems such as the most wear-resisting, perishable and fouling is serious in existing polyethylene pipe when carrying material.The Chinese utility model patent of entitled " super high molecular weight enhanced polyethylene pipe " Application No. " 201220391017.0 " discloses a kind of super high molecular weight enhanced polyethylene pipe, it is provided with internal layer and outer layer, described internal layer is ultra-high molecular weight polyethylene internal layer, and outer layer is high density polyethylene (HDPE) outer layer；The molecular weight of described ultra-high molecular weight polyethylene internal layer is more than 1,500,000 dalton, and the molecular weight of high density polyethylene (HDPE) outer layer is 4 ten thousand to 12 ten thousand dalton；The thickness of described ultra-high molecular weight polyethylene internal layer is equal with the thickness of high density polyethylene (HDPE) outer layer.But, although this product has certain wear-resistant, impact resistance, anticorrosion effect, but, product strength is relatively low, and impact resistance is poor, and service life is shorter.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of novel high impact polyethylene tubing, not only has higher pressure performance, has again excellent impact resistance simultaneously, and intensity is high, and service life is long.
The technical solution of the utility model is:
A kind of novel high impact polyethylene tubing, including internal layer and outer layer, described internal layer is white low-pressure high-density polyethylene layer, described outer layer is hp-ldpe layer, internal layer directly contacts with defeated water, for preventing water be contaminated at tubing course of conveying and affect, white low-pressure high-density polyethylene layer is without any additive；Integrally being bonded with one layer of winding steel wire layer by hot melt adhesive layer between described internal layer and outer layer, thus not only make product have higher pressure performance, have again excellent flexibility simultaneously, and connect fixation, be difficult to layering, service life is long；Described winding steel wire layer includes that two-layer is respectively the meshy steel wire skeleton that left-and-right spiral is Wrapping formed, and internal pressure-resistant is high, and flexibility is good, and the life-span is long.
Further, the inner side of described internal layer is provided with composite antibacterial oxidant layer, described complex antimicrobials is inorganic nano silver antibacterial agent and polymer antibacterial agent, formed by adding processing aid co-extrusion, synergism by polymer antibacterial agent Yu inorganic nano silver antibacterial agent, make antimicrobial efficiency high, simultaneously because slow-release function specific to polymer antibacterial agent, make antibacterial effect more longlasting.
Further, the outside of described outer layer is provided with layer of polyurethane, and the outside of described layer of polyurethane is provided with polyether-ether-ketone layer so that pipeline has good insulation heat resistance；The inside of described layer of polyurethane is distributed iron powder and/or quartz sand, improves intensity and the puncture-resistant effect of product.
Additionally, plasticity rod it is provided with inside described tubing, described plasticity rod is flexible rod, such as elastic rubber-plastic composite material bar, or elastoplast rod, or gum elastic rod, or modified rubber rod, there is plasticity rod owing to running through in tubing, when the water in tubing is because of the RADIAL amount of sky the caused volumetric expansion of cold junction ice, can be dissolved by the radial plastic deformation of flexible rod, " absorption ", thus effectively prevent the bursting by freezing of water pipe.
The utility model has the advantage of: not only have higher pressure performance, having again excellent impact resistance, intensity is high, and service life is long simultaneously.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the radial cross-section of this utility model embodiment composite pipe.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment 1
As shown in Figure 1, a kind of novel high impact polyethylene tubing, including internal layer 1 and outer layer 2, described internal layer is white low-pressure high-density polyethylene layer, described outer layer is hp-ldpe layer, internal layer 1 directly contacts with defeated water, and for preventing water be contaminated at tubing course of conveying and affect, white low-pressure high-density polyethylene layer is without any additive；Integrally being bonded with one layer of winding steel wire layer 5 by hot melt adhesive layer 3 between described internal layer 1 and outer layer 2, thus not only make product have higher pressure performance, have again excellent flexibility simultaneously, and connect fixation, be difficult to layering, service life is long；Described winding steel wire layer includes that two-layer is respectively the meshy steel wire skeleton that left-and-right spiral is Wrapping formed, and internal pressure-resistant is high, and flexibility is good, and the life-span is long；The inner side of described internal layer 2 is provided with composite antibacterial oxidant layer 4, described complex antimicrobials is inorganic nano silver antibacterial agent and polymer antibacterial agent, formed by adding processing aid co-extrusion, synergism by polymer antibacterial agent Yu inorganic nano silver antibacterial agent, make antimicrobial efficiency high, simultaneously because slow-release function specific to polymer antibacterial agent, make antibacterial effect more longlasting.
The outside of described outer layer 2 is provided with layer of polyurethane 6, and the outside of described layer of polyurethane 6 is provided with polyether-ether-ketone layer so that pipeline has good insulation heat resistance；The inside of described layer of polyurethane is distributed iron powder and/or quartz sand, improves intensity and the puncture-resistant effect of product.
