Abstract
The invention discloses a raw material formula of a nanometer carbon fiber composite cable protection pipe, which comprises the following raw material ingredients: alkali-free glass fiber yarn, 191 Rugby liquid resin, methyl ethyl ketone, curing agents, nanometer light calcium carbonate with the particle size smaller than 200 nanometers, carbon fibers and aluminum oxide. The nanometer carbon fibercomposite cable protection pipe produced by the technical scheme of the invention has the advantage of good comprehensive performance of tensile strength, bending strength and sweating soldering strength, and is especially suitable for the performance requirements for the cable protection pipe by a non-excavation direct-buried construction method.
Description
Technical field
The present invention relates to the power cable technology, be specifically related to a kind of composition of raw materials of nanometer carbon fiber composite cable protection pipe, the protective tube that adopts this prescription to produce is particularly useful for adopting non-excavation push pipe method for directly burying to carry out using when cable is constructed with burying.
Background technology
Along with the needs of power industry and urban construction and development, aerial line changes into from underfloor cabling, and the method for employing non-digging direct-buried mode cable laying more and more receives an acclaim and payes attention to.But adopt non-digging direct-buried constructional method that the performance of cable protection pipe is had its corresponding adaptability requirement.
The existing cable protective tube adopts plastics tubings such as modified polypropene, chlorinated polyvinyl chloride, modified polyvinyl chloride mostly, and cement asbestos tube, steel pipe etc.Above-mentioned cable protection pipe or have the defective of tension, flexural strength difference, or have the defective that welding strength is low even sweating soldering is difficult often causes in non-digging direct-buried cable laying construction that operating efficiency is low, construction cost increases.
Summary of the invention
The composition of raw materials that the purpose of this invention is to provide a kind of nanometer carbon fiber composite cable protection pipe, its over-all properties of cable protection pipe that adopts this prescription to produce are suitable for adopting non-excavation push pipe method for directly burying to carry out cable constructing with burying.
Technical solution of the present invention is as follows:
A kind of composition of raw materials of nanometer carbon fiber composite cable protection pipe, its raw material composition and content thereof are as follows:
Alkali-free glass fibre yarn 50%,
191 liquid glug resins 35%,
Potassium second copper 0.5%,
Solidifying agent 0.5%,
Particle diameter is less than the nanometer light calcium carbonate 8% of rice in 200,
Carbon element fibre 3%,
Aluminum oxide 3%.
The nanometer carbon fiber composite cable protection pipe of producing with technique scheme has the advantage of tensile strength, flexural strength and sweating soldering intensity good combination property, especially is fit to the performance requriements of non-digging direct-buried constructional method to cable protection pipe.
Embodiment
The composition of raw materials that provides by the invention described above technical scheme, with powder raw material mixing post-heating to 110 ℃ ± 2 ℃, about 3 minutes of soaking time, promptly enter volume then and be twice the above cold pot of kneading and mix and stir, about 5 minutes of cold mixing time, send into the twin screw extruder extrusion moulding after sieving again.
After tested, the performance data of the nanometer carbon fiber composite cable protection pipe of producing with composition of raw materials of the present invention is as follows:
Density is 1.80～2.00g/cm
3When envrionment temperature is 23 ± 2 ℃, tensile strength 〉=180Mpa, flexural strength 〉=200Mpa, modulus in flexure 13Gpa; The crooked strength retention ratio in immersion back 〉=80%; Heat-drawn wire 〉=140 ℃; Frictional coefficient≤0.34; Barcol hardness 〉=38; Degree of cure 〉=80%; Thermal conductivity 〉=0.24W/WK; Oxygen index 〉=80%.
