Described rigid support member cross section is one of triangle, rectangle, circle.
Described duroplastss are thermosetting plastics, are bakelite, polyurethane plastics, epoxy plastics, furan plastic, propylene One of base resin;
Described metal is duralumin, hard alumin ium alloy for 7;
Described phase-change material is the material such as aliphatic hydrocarbon, fatty acid, fatty alcohol, fatty acid ester or its mixture.
Described thermal insulation layer also contains fire retardant, and the composition of thermal insulation layer is by weight percentage: paraffin 40%-55%, and ten Eight alkane 20%-25%, ten difatty acid 15%-25%, fire retardant 10%-20%.Fire retardant is selected from triazine carbon forming agent, polyphosphoric acid Ammonium, tetrabromobisphenol a, TDE, brominated epoxy etc., especially preferably adopt response type phosphonic acids ester monomer and Ji Wusi The cross linked polymer of alcohol tetraacrylate.
Described fire-retardant filler for particle diameter be 2 μm~4 μm aluminum hydroxide particles or magnesium hydroxide particle.
Between described GRP pipe main body and rigid support member, also fill up between rigid support member and thermal insulation layer Flexible cushion,
The present invention is with respect to the advantage of prior art:
Employ rigid support member, stable load knot can be formed during transport, carrying, installation, using Structure, plays, to internal GRP pipe main body, the effect of being effectively protected, greatly extends the range of application of glass, in addition every Thermosphere adopts phase-change material, and when environment is in high temperature around, this layer can absorb heat, the temperature but keeing relative stability in a large number Degree, is conducive to the underground cable normal work of internal layer, improves safety.
Brief description
Fig. 1 is pressure high temperature resistant glass fibre reinforced plastic pipeline configuration schematic diagram disclosed by the invention.
In figure: 1- GRP pipe main body, 2- rigid support member, 3- thermal insulation layer, 4- flame retardant insulation.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, the invention discloses a kind of pressure pyroceram steel conduit, including set gradually from inside to outside GRP pipe main body 1, rigid support member 2, thermal insulation layer 3 and flame retardant insulation 4;
Described GRP pipe main body is located at inner side, and internal diameter is 100-200mm, and thickness is 2-10mm;It is applied to sea The cable channel of ocean, building site, high -temperature workshop etc., outside sheathed rigid support member, in the little place of desired strength, can adopt The duroplastss such as bakelite, polyurethane plastics, epoxy plastics, furan plastic, allyl resin as rigid support member, to subtract The weight of light integrated piping reduces cost, are frequently bearing pressure, are requiring the stronger place of pipeline anti-pressure ability, can take As frame material, what especially preferred hardness was larger 7 is duralumin, hard alumin ium alloy to aluminium alloy, and described duroplastss or aluminum alloy frame Cross section can be triangle;To maintain stable load-carrying construction, and be easy to fixing, certainly may also be employed as needed rectangle or Circular configuration, outside thermal insulation layer and flame retardant insulation can make round-shaped it is also possible to duroplastss or aluminum alloy frame Make profile-followed triangle or rectangular shape is beneficial to stacking transport.
Outside rigid support member, described thermal insulation layer is filled with aliphatic hydrocarbon, fatty acid, fat to described thermal insulation layer The phase-change material such as the materials such as alcohol, fatty acid ester or its mixture coordinates corresponding function ingredients it is preferred that the composition of thermal insulation layer is pressed Weight percent content is: paraffin 40%-55%, octadecane 20%-25%, ten difatty acid 15%-25%, fire retardant 10%-20%, wherein fire retardant are selected from triazine carbon forming agent, APP, tetrabromobisphenol a, TDE, brominated epoxy Deng, especially preferably fire retardant adopts the cross linked polymer of response type phosphonic acids ester monomer and tetramethylol methane tetraacrylate, its There is some strength, as thermal insulation layer outer wall, and can have fire-retardant and waterproof effect, be particularly suited for causing fire in high temperature Protective conduit during calamity, the phase transition temperature of this thermal insulation layer is about 40 DEG C~55 DEG C, this layer material temperature in fusing or process of setting Change is little, but in the temperature range of very little, the latent heat of absorption or release is quite big, applies in the present invention, around environment When being in high temperature, heat, the temperature but keeing relative stability can be absorbed in a large number, be conducive to the normal work of underground cable of internal layer Make, and described flame retardant insulation be outside thermal insulation layer, for being filled with the organosilicon epoxy resin of fire-retardant filler, play fire-retardant simultaneously The effect of insulation, described fire proofing for particle diameter be 2 μm -4 μm aluminum hydroxide particles or magnesium hydroxide particle, fire-retardant filler Quality account for the 20%-30% of organosilicon epoxy resin.
Additionally, when duroplastss or aluminum alloy frame section are triangle or rectangle, can be in GRP pipe main body with just Property support member between, between GRP pipe main body and framework, elastic cord breaker between framework and outer layer, can be filled with, should Elastic cord breaker plays a protective role to the GRP pipe main body of internal layer, it is to avoid the shock producing in carrying and work progress Destruction to fiberglass, the material such as soft rubber that this elastic cord breaker can select to have porous.
In addition, being directed to the present invention, according to the needs of concrete application occasion, can increase by the virtue being soaked with resin in outermost layer The high voltage shield that synthetic fibre fiber spiral is entwined, and/or it is coated with the non-woven fabrics of resin, to play high-tension shielding and/or to prevent The effect of water.
The above, be only presently preferred embodiments of the present invention, not the present invention imposed any restrictions, every according to the present invention Any simple modification, change and equivalent structure change that technical spirit is made to above example, all still fall within skill of the present invention In the protection domain of art scheme.
