Technical field
The invention belongs to the pipework field, specifically is that a kind of products pipeline reparation is with leading static liner and method of manufacture thereof.Be mainly used in products pipeline system and chemical engineering piping systems etc.
Background technology
Epoxy resin not only has characteristics such as closely knit, anti-water, anti-leakage are good, intensity height as anticorrosive, have favorable manufacturability such as strong adhesion, normal-temperature operation, shaping performance excellence, easy construction simultaneously, and moderate.Be widely used a kind of material in non-excavation pipeline rehabilitation technology at present, can use in the engineering in the fields such as reparation of urban water supply and sewerage, crude oil pipeline etc. in modern times.
But along with the development of pipeline non-excavation repairing technique, the inner lining material that is applied to the products pipeline reparation requires increasingly high to the electrostatic conductive performance of himself.With the rocket(engine)fuel is example; Require under many circumstances to be filled into oil product specific conductivity on the aircraft at 50～450pS/m, and epoxy resin itself is a kind of good superior isolation material with high dielectric property, anti-surface leakage, anti-electric arc, after with it old product pipeline being repaired through pipeline; The oil product flow velocity increases; Internal friction increases, and compares with original steel pipeline, and existing liner repair layer is easy to cause electrostatic accumulation and can't be dissipated in the surrounding environment; Make the specific conductivity that is filled into the oil product on the aircraft defective, bring serious hidden danger for the flight safety of aircraft.
At present; The method of general raising epoxide resin material electrostatic conductive performance is in material, to add conductive materials such as carbon black, iron powder; But this method receives the restriction of conductive filler material self performance very big, but also can make the Material Physics mechanical property after the curing can not be up to standard, does not have feasibility.What be not specifically designed to also in the world at present that the products pipeline reparation uses leads the electrostatic inner lining material with epoxy resin as matrix.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art,, provide a kind of products pipeline reparation with leading static air retaining wall and method of manufacture thereof with efficient electrostatic conductiveness in conjunction with the progress of modern nanotechnology.On the basis that guarantees the Material Physics mechanical property, improve the electrostatic conductive performance that products pipeline is repaired inner lining material.
The present invention realizes with following technical scheme: a kind of products pipeline reparation is with leading the electrostatic liner, and it comprises the TPUE of the piped surface attachment nylon fibre that cooperates with products pipeline and soaks Tianjin from outside surface and go into and lead electrostatic liner slurry on it; The described electrostatic liner slurry of leading is that each component thorough mixing of following mass parts is processed after evenly:
Epoxy resin: 70-80 part
Spun glass: 10-20 part
Mica modified carbon nano-tube: 5-10 part
Acid anhydrides: 20-40 part.
Described epoxy resin is E6101 type epoxy resin.
Described nylon fibre is the TPU-nylon fibre.
Above-mentioned products pipeline reparation is with leading the method for manufacture of electrostatic liner, and concrete steps are following:
(1) process the TPUE of surface attachment nylon fibre tubular earlier;
(2) electrostatic liner slurry is led in preparation: mica compound CNT filler is added in the epoxy resin by formula rate, add glass fibre reinforcement, and then add high-temperature curing agent, must lead electrostatic liner slurry after thorough mixing is even;
(3) the TPUE material with piped surface attachment nylon fibre soaks Tianjin in leading electrostatic liner slurry, and fully soaks into;
(4) will soak the end sealing that there is the tubular thermoplastic polyurethane elastomer of leading electrostatic liner slurry in Tianjin then; Place pipeline to be repaired, be not less than at the other end and charge into 100-120 ℃ water vapour body under the pressure of 0.3Mpa and make it make its curing molding and combine closely on inner-walls of duct.
Used the E6101 epoxy resin among the present invention, its oxirane value is high, and it is big to solidify the back product strength; Chemical property is stable; The corrosion of oil resistant, bronsted lowry acids and bases bronsted lowry has excellent physical strength, surface hardness, gas barrier property, organic solvent resistance, and the solidification value scope can be from 0～180 ℃; Characteristics such as adhesivity is strong, and shrinking percentage is low.The anhydride curing agent that adopts has the solidification value height, set time may command with the characteristics of being convenient to construct.
Having used TPUE (TPU) to make base material among the present invention, is to be used for the non-trenchless rehabilitation inner lining material of pipeline matrix.The main characteristic of TPU has: durometer level is wide, can obtain the product of different hardness through changing the proportioning of each reactive component of TPU, and along with the increase of hardness, its product still keeps good elasticity and wear resistance.Physical strength is high, and the supporting capacity of TPU goods, shock resistance and damping performance are outstanding.Winter hardiness is outstanding, and the glass transition temperature of TPU is lower, still keeps good elasticity, kindliness and other physicalies at subzero 35 degree.The hydrocarbon solvent nature of oil resistant, lubricating oil and aliphatics is outstanding.Can effectively solve the problem that mixes of hydrocarbon compound in sill and the processed oil.
Used the polyamide fabric fiber reinforcement among the present invention,, all met request for utilization, when guaranteeing repairing effect, increased the intensity of solidifying the back material effectively at aspects such as thickness, elasticity, brute force, Young's modulus through specially designed.
Used acid anhydrides to be solidifying agent among the present invention, material solidifies under higher temperature, therefore can give the long engineering time at normal temperatures, avoids causing constructional difficulties because of the material premature setting.
Used the mica modified carbon nano-tubes to make filler among the present invention.Carbon nanotube is the stable permanent electro-conductive material of a kind of chemical property.The big π key of its delocalization makes electric charge be easy to move on the surface, and the tunnel effect of diameter and termination nano-scale is remarkable, is highly advantageous to discharge entrained static charge, has excellent machinery and Electronic Performance.Can be controlled at several microns to tens of microns through distance between the mica modified carbon nanotube; Overcome that common nano material is assembled easily, a difficulties in dispersion difficult problem; Make carbon nanotube in base-material, be easy to disperse; The interpolation very small amount just can reach leads the electrostatic technique requirement, and can also reduce use cost effectively.
The invention has the beneficial effects as follows: with existing be that the pipeline rehabilitation material of base material is compared with epoxy resin; Have good physical and mechanical properties, erosion resistance, resistance to deterioration; Has good electrostatic conductive performance simultaneously; Can effectively reduce the electrostatic accumulation phenomenon that causes because of material and oil product internal friction, guarantee to be filled into the requirement of processed oil specific conductivity National standard on the aircraft, guarantee flight safety.Also can be used for the industrial chemicals conveying and wait other occasions strict to electrostatic conductive performance, purposes is comparatively extensive.
