Abstract
An impact-resistant high-strength PE (polyethylene) plastic alloy gas pipe comprises a pipe body. A lining of the pipe body is a UHMWPE/PP (molecular weight polyethylene/polypropylene) plastic alloy core pipe. A stainless steel mesh layer is sleeved outside a PE plastic layer. A thermoplastic elastomer polyethylene layer is disposed outside the stainless steel mesh layer. A plurality of metal wires are disposed in the PE plastic layer. The impact-resistant high-strength PE plastic alloy gas pipe has the advantages of safety in use, high impact resistance, high pressure resistance, high weather resistance and the like. The UHMWPE/PP plastic alloy core pipe is corrosion-resistant, durable and resistant to corrosion of various corrosive media such as acid, alkali and salt. The stainless steel mesh layer enhances the pressure resistance of the pipe and enables the pipe to be less prone to cracking and durable for 60 years. The metal wires in the PE plastic layer are very thin. After the metal wires are connected to an alarm, the alarm can timely reflect failures of the PED gas pipe such as cracking and leakage and send out warning timely. The thermoplastic elastomer polyethylene layer keeps the temperature of the pipe less susceptible to environment.
Description
Technical field
The utility model relates to a kind of PE Plastic Gas Pipe, particularly a kind of shock resistance, high strength PE plastic alloy fuel tube.
Background technique
When the use of rock gas was more and more general, the installation requirements of pipeline were also more and more.Fuel tube must be born certain pressure, will select usually that molecular weight is large, the PE resin of better mechanical property.The melt viscosity of PE resin is little, good fluidity, easily processing.To be polymerized by monomer ethylene, since different because of polymeric reaction conditions such as pressure, temperature when polymerization, can draw the resin of different densities, thereby arranged dividing of high density polyethylene (HDPE), medium density polyethylene and Low Density Polyethylene again.Fuel tube elongation at break 〉=350, weather resisteant can be satisfied HS(65h/80 ℃) the elongation at break requirement; Resistibility of slow crack growth en〉5mm will reach 165h; Thermostability (oxidation induction period, 200 ℃)〉20min.But make a general survey of existing PE fuel tube, ubiquity that impact resistance is poor, compressive strength is not high, is subject to climatic impact, the defective such as not sun-resistant.
Summary of the invention
The technical problems such as the purpose of this utility model is that a kind of shock resistance, high strength PE plastic alloy fuel tube will be provided, and existing fuel tube impact resistance is poor, compressive strength is not high to solve, be subject to climatic impact, not sun-resistant.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of shock resistance, high strength PE plastic alloy fuel tube, comprise body, described body nexine is UHMWPE/PP plastic alloy core pipe, UHMWPE/PP plastic alloy core pipe outer race is provided with the stainless steel stratum reticulare, stainless steel stratum reticulare periphery is provided with the thermoplastic elastomer polyethylene layer, is provided with many one metal wires in the described UHMWPE/PP plastic alloy core pipe.
As preferably, described wire is distributed on the peripheral wall of UHMWPE/PP plastic alloy core pipe, and this wire ends is connected with alarm.
Wire is very thin in the UHMWPE/PP plastic alloy core pipe, and after alarm was connected, alarm can reflect in time whether the PE fuel tube exists fault and and the alarms such as the gas leakage of breaking.The thermoplastic elastomer polyethylene layer can keep the temperature of pipeline not to be subject to the impact of environment.
The utlity model has safety, the characteristics such as impact resistance is strong, compressive strength is high, good weatherability used.Wherein UHMWPE/PP alloy core pipe layer is corrosion-resistant, and long service life can acid-and base-resisting, the erosion of the various Korrosionsmediums such as salt; The stainless steel stratum reticulare can increase compressive strength of the present utility model, impels it to be difficult for breaking, and can reach 60 years its working life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model fuel tube.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model; Fig. 2 is the sectional view of the utility model fuel tube.By Fig. 1 in conjunction with Fig. 2 as can be known, this shock resistance, high strength PE plastic alloy fuel tube mainly are made of body 1, thermoplastic elastomer polyethylene layer 2, stainless steel stratum reticulare 3 etc.Body 1 nexine is UHMWPE/PP plastic alloy core pipe 5, and UHMWPE/PP plastic alloy core pipe 5 outer race are provided with stainless steel stratum reticulare 3, and stainless steel stratum reticulare 3 peripheries are provided with thermoplastic elastomer polyethylene layer 2.Be provided with stainless steel stratum reticulare 3 between UHMWPE/PP plastic alloy core pipe 5 and the thermoplastic elastomer polyethylene layer 2.Be provided with wire 51 in the UHMWPE/PP plastic alloy core pipe 5, wire 51 preferably is distributed in more than 3 or 3 on the peripheral wall of UHMWPE/PP plastic alloy core pipe 5, and this wire ends is connected with alarm 6.
Below be the several examples during the PE fuel tube is made.
Embodiment 1: take TPV polyolefin alloy thermoplastic elastomer (TPE) as bulking agent, carry out melting mixing with four screw extruder and prepare UHMWPE/PP plastic alloy core pipe; With 50 parts of polyethylene, 0.2 part of 1 part of sorbitol of nano titanium oxide drops in the second extruder hopper after 3 parts of mixing of TPUE by weight; During production, the first extruder is extruded UHMWPE/PP plastic alloy core pipe 5, simultaneously wire 51 is covered, then behind UHMWPE/PP plastic alloy core pipe 5 process water-cooleds and the sizing, Stainless Steel Wire is wrapped on the UHMWPE/PP plastic alloy core pipe 5 from the mode of the right and left with left-handed dextrorotation respectively, the angle of twining is 50 degree, so that tubing is axial and the hoop uniform stressed, forms the first stainless steel stratum reticulare 3.After UHMWPE/PP plastic alloy core pipe 5 twines through heating, thermoplastic elastomer polyethylene layer 2 is extruded UHMWPE/PP plastic alloy core pipe 5 parcels by the second extruder, guarantee that hot melt sticks to one between high-tensile steel wires and the internal and external layer, thereby obtain excellent PE fuel tube.
Embodiment 2: take TPV polyolefin alloy thermoplastic elastomer (TPE) as bulking agent, carry out melting mixing with four screw extruder and prepare UHMWPE/PP plastic alloy core pipe; With 50 parts of polyethylene resins, 2 parts of nano titanium oxides, 1.1 parts of sorbitols drop in the second extruder hopper after 8 parts of mixing of TPUE by weight; The mode of production is the same.
When UHMWPE content is 13% when above, the alloy impact strength reaches maximum value, has formed " linear inierpeneirating network structure " in the alloy, and namely the skeleton of the overlength molecular chain constituent material of UHMWPE can play toughness reinforcing and humidification to the polypropylene main body.In addition, owing to added TPUE in the thermoplastic elastomer polyethylene layer 2.Elastomer has good combination to multilaminar polyethylene, with sorbitol synergy, can effectively improve the toughness of goods and rigidity, heat distortion temperature, dimensional stability.So that three-layer composite structure of the present utility model has good strength, wear-resisting property.
