Abstract
The invention provides an improved composite material cable conduit and a technology method thereof. The technology method comprises the processing steps of using a CPVC (Chlorinated Polyvinyl Chloride) cable conduit as a lining (10) and covering the lining by using a glass fiber reinforced plastic (FRP) (20), wherein the FRP (20) is formed by closely, sequentially and repeatedly winding alkali-free glass fiber roving or a glass fiber woven belt fully steeped in unsaturated polyester resin (UPR) on the surface of a CPVC tubular product; the UPR is uniformly mixed in cyclohexanone peroxide (CYHP) serving as a curing agent; after the UPR is cured, the roving or the woven belt fully steeped in the UPR and the CPVC tubular product serving the lining (10) are firmly bonded into an overall bearing cable conduit. The improved composite material cable conduit has the advantages of high strength and high heat resistance of the FRP and good toughness and low cost of the CPVC tubular product. After a cable penetrates into the improved composite material cable conduit, the cable is free of being damaged by burrs on the inner wall of the conduit and is capable of bearing the abrupt changes of foundation conditions such as geological sedimentation and other natural hazards while having excellent compressive property.
Description
technical fieldthe present invention relates to the protective conduit that power cable laying must be used, relate in particular to the composite material cable conduit that uses two or more nonmetallic materials to make, particularly relate to heat-resisting, the corrosion resistant high-strength cable conduit that covers fiberglass reinforced plastics FRP with modified polyvinyl chloride M-PVC tubing outward.
background technologyprior art is commonly used fiberglass reinforced plastics FRP, be commonly called as the cable duct tube of " fiberglass ", be to take synthetic resin as binding material, take continuous multiply e-glass fiber roving and/or its fabric is reinforcing material, by a kind of tubing of computer control winding process moulding.This kind of tubing has the characteristics such as electrical insulation capability that intensity is high, corrosion-resistant, fire-retardant, heat-resisting and good.The described tubing as cable duct tube is non magnetic material, without eddy current loss and galvano-cautery, is easily producing under the alternating electromagnetism field condition of eddy current, can not cause electric cable heating to damage.But, in real production process, synthetic resin is difficult to the complete wetting glass fibre, so that after the moisture evaporation, pipe material inner wall fineness is poor, jagged, easily the scratch cable; And great majority " fiberglass ", the tubing of glass fiber reinforced epoxy resin for example, quality is partially hard, flexible not enough, if in the place of using its power cable laying, foundation settlement occurs, described tubing very easily ruptures and is difficult to and repairs.
Prior art is normal polyvinylchloride and/or the polypropylene PP tubing of using separately also, and pvc pipe material raw material is cheap and easy to get, convenient processing, and its finished product has mechanical performance and decay resistance preferably, but the normal working temperature that can tolerate is on the low side.PP tubing also has mechanical performance and decay resistance preferably, and the normal working temperature that can tolerate is higher than pvc pipe material, and but to low-temperature sensitive, along with temperature descends, its mechanical property obviously descends, and its ageing-resistant performance is also poor in addition.
Comprehensively above-mentioned, be power cable laying, especially lay the power cable line of underground 110kV grade, prior art is used separately FRP tubing, or PVC, PP tubing can not meet the demands well as cable duct tube, have a strong impact on the safe operation of underground power cable circuit.
summary of the inventionthe technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of in conjunction with modified polyvinyl chloride, for example, in conjunction with the chlorinated polyvinyl chloride CPVC tubing of excellent insulation performance, and the unsaturated polyester resin UPR that uses high-performance/cost ratio strengthens technology as the glass fibre of binding agent and formulates, can meet and lay that underground 110kV grade power cable line requires, modified model composite material cable conduit and process thereof.Though the chlorinated polyvinyl chloride CPVC tubing as modified polyvinyl chloride M-PVC product has good flexibility and inwall fineness, ring wall rigidity is lower.By being wound around e-glass fiber roving or fiberglass braided band, glass fabric thereon, and make it to be combined into the one of integrated carrying with CPVC tubing and the requirement that reaches high strength, high tenacity with binding agent.Cable duct tube after moulding of the present invention, CPVC tubing is liner, and FRP is overcoat, and the two tight bond is one tubing.After penetrating cable, building up the high-tension transmission circuit, described cable duct tube is that integral body is born mechanical loading, and certain toughness is arranged, so be not easy to fracture, very strong opposing immerge ability is arranged.
The technical scheme that the present invention solve the technical problem employing is that a kind of modified model composite material cable conduit, comprise that the tubing of using modified polyvinyl chloride M-PVC resin extrusion moulding, as liner, covers fiberglass reinforced plastics FRP outward; The described outer fiberglass reinforced plastics FRP covered is that e-glass fiber roving or the fiberglass braided band that fully floods unsaturated polyester resin UPR closely, sequentially repeatedly is wound in the described M-PVC of the modified polyvinyl chloride as liner tube surfaces and forms; After described unsaturated polyester resin UPR solidifies, the e-glass fiber roving or the fiberglass braided band that have flooded this unsaturated polyester resin UPR bond securely and become integrated carrying, described composite material cable conduit with the modified polyvinyl chloride M-PVC tubing as liner.
The described tubing with modified polyvinyl chloride M-PVC resin extrusion moulding is commercially available chlorinated polyvinyl chloride CPVC cable duct tube, carrying out substitution reaction by the polyvinylchloride of the specific trade mark and chlorine Cl under the initator effect makes, English full name is Chlorinated Polyvinyl Chloride, it is a kind of model engineering plastic, chemical stability increases, thereby it is heat-resisting to have improved material, and the corrosion of acid and alkali resistance, salt, oxidant etc., and maximum operation (service) temperature can reach 110 ° of C.
The e-glass fiber roving of described abundant dipping unsaturated polyester resin UPR or fiberglass braided band, be fully to have flooded to take cyclohexanone peroxide CYHP as curing agent, evenly admixes the unsaturated polyester resin UPR in it.The English full name of described unsaturated polyester resin UPR is unsaturated polyester resin.The present invention is for the curing agent of this unsaturated polyester resin UPR, the English full name of described cyclohexanone peroxide CYHP is cyclohexanone peroxide, it belongs to the peroxide initiator of medium activity, share the composition redox initiation system with reducing agent, as the crosslinking curing initator of unsaturated polyester binding agent.Coordinate again the cobalt Co catalyst of 1% ratio by weight, can reach curing effect under 15 ° of above normal temperature of C.With methyl ethyl ketone peroxide, MEKP compares, and its advantage is that exothermic peak temperature is lower, the solidfied material internal stress is less, colour stable.
Compared with the existing technology, beneficial effect of the present invention is, described modified model composite material cable conduit not only has the high strength of fiberglass reinforced plastics FRP, the advantage of high-fire resistance, have again modified polyvinyl chloride M-PVC tubing good toughness, cheap advantage concurrently simultaneously, power cable penetrates in it and can not damage because of the burr of described pipe inner wall, the unexpected variation that described conduit can also bear foundation situation when having good compressive property on the contrary, as natural calamities such as geology sedimentations.
