Abstract
The present invention is the production process composite GRP cable-protecting pipe. The base material includes unsaturated resin, Sb2O3, decabromodiphenyl oxide or oxidized petroleum wax, cobalt solution, talcum powder or quartz sand or calcium carbonate, and methyl ethyl ketone. The base material and glass fiber fabric or roving in the weight ratio of 4-4.5 to 5.5-6 are used to produce the cable-protecting pipe. The cable-protecting pipe has light weight, low cost, high strength, small heat resistance, high fireproof property, high cold resistance, etc.
Description
Technical field
The present invention relates to a kind of manufacture method of cable-protecting composite GRP pipe.
Background technology
Along with the high speed of urban construction is carried out, City Buried Pipeline is more and more, and becomes increasingly complex, and available space is also more and more littler, and this requires the science of programmingization of urban underground space.Traditional city cable construction is adopted to dig and is established plastics tubing or cement pipe or galvanized steel pipe, or build by laying bricks or stones and mix the method cable laying of doubting native cable trench and electric power tunnel, but all there are major defect in above-mentioned construction material and method, the plastics tubing use temperature is low, intensity difference is embedded in undergroundly under the effect of cable operating temperature 60～70 degree and water for a long time, and plastics tubing can produce decomposition, strength degradation is aging, and is yielding and break under the ambient pressure effect.Galvanized steel pipe is perishable, yarn non-insulating material again, and easily operation results from magnetic to cable, and matter high price height, and construction is inconvenient, and the electric welding reverse interface easily makes cable skin pull.And the mixed doubtful native cable trench engineering time is long, often will open cover plate when maintaining and safeguarding increases labour intensity, also influences the Urban traffic and the appearance of the city, and easy ponding easily makes cable bad in the cable trench, be the good living space of muroid on the other hand in the cable trench, the infectivity disease.The electric power tunnel engineering time is long, and construction investment is big, and fire-fighting and ventilation are difficult to solve.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of cable-protecting composite GRP pipe; the cable protection pipe that uses this method to make has in light weight; cost is low; the intensity height; current capacity is big, and thermal resistance is little, heat-resisting heat radiation and fire-retardant and cold tolerance good; and have a use face width, advantage safe and convenient to use.The present invention adopts following proportioning raw materials to make cable protection pipe of the present invention for this reason, 100 parts of unsaturated polyesters, 5 parts of antimonous oxides, 5～15 parts of decabromodiphynly oxides; or 10～15 parts of oxidized petroleum waxs, 0.6～3 part in cobalt water, talcum powder; or quartz sand, or 5～15 parts in lime carbonate, 1～4 part of methylethylketone.
The base-material of above-mentioned preparation and glasscloth, or the weight ratio of rove is 4～4.5: 5.5～6.
Aforesaid method has been realized purpose of the present invention.Advantage of the present invention is the intensity height, is used for the runway direct-burried, need not to add concrete cover, and intensity generally exceeds more than 6 times than the plastics and the nylon tube of condition of equivalent thickness.Current capacity is big, and thermal resistance is little, and perfect heat-dissipating does not have any disadvantageous effect to the works better of cable.Insulation, non magnetic, no eddy-current loss and electrocorrosion, energy-conservation are applicable to single stamen cable running, corrosion-resistant can the use in the high salinity area.Body has flexibility, and is supporting again with flexible joint, can resist extraneous weight and foundation settlement.Fire-retardant, resistance toheat good, can 120 the degree high temperature under life-time service indeformable.Cold tolerance is good, can use under negative 30 degree, and the intensity and the flexibility of pipe do not change.Smooth stingless, easily wear cable, not scratch cable, good airproof performance, cost is low, and cost only is 20% of traditional structure, and is in light weight, and installation is convenient, and has the use face width, advantage safe and convenient to use.
Embodiment
Base-material of the present invention adopts unsaturated polyester, can adopt market to sell 191 types, 196 types, or 189 type unsaturated polyesters, and the unsaturated polyester of above-mentioned model can use separately, also can be mixed in proportion use.
Used raw material composition and proportioning are as follows:
5 parts of 100 parts of antimonous oxides of unsaturated polyester
5～15 parts of decabromodiphynly oxides, or 0.6～3 part in 10～15 parts of cobalt water of oxidized petroleum wax
Talcum powder, or quartz sand, or 1～4 part of 5～15 parts of methylethylketone of lime carbonate
The base-material of above-mentioned preparation and glasscloth, or the weight ratio of rove is 4～4.5: 5.5～6.
Described glasscloth is middle alkali, or does not have alkaline glasscloth, and described rove is a roving.Mould of the present invention adopts the weldless steel tube processing of 45 models, stamps butter or machine oil on mould, spreads mylar.Glasscloth in the base-material that is immersed in preparation and yarn are wrapped on the mould, mould is made garden Zhou Xuanzhuan in winding process, and per minute rotating speed 60～200 changes, usually according to variant production thickness, the glasscloth of the different numbers of plies and yarn in the winding, the number of plies is 9～20 layers usually.After winding finishes, treat that 10 minutes after fixing finish, product is lifted to the demoulding on the stripper, with cutting machine product two ends surplus is removed then and got final product.
In a word, the cable protection pipe made from the inventive method has in light weight, and cost is low, the intensity height, and current capacity is big, and thermal resistance is little, heat-resisting heat radiation and fire-retardant and cold tolerance good, and have the use face width, advantage safe and convenient to use can be promoted the use of.
Claims (2)
1, a kind of manufacture method of cable-protecting composite GRP pipe is characterized in that, used raw material composition and proportioning are as follows:
5 parts of 100 parts of antimonous oxides of unsaturated polyester
