Description
Technical field:
The present invention relates to a kind of organic fire-resisting cable-protecting composite GRP pipe and production method thereof, be applicable to urban network reconstruction, the construction of traffic road and bridge engineering and the buried construction of communication cable etc.
Background technology:
At present, the product as cable protection pipe mainly contains: tubing such as asbestos cement conduit, tremie, pvc pipe, steel pipe.In the cable work that difference requires was built, adopted respectively according to self characteristics and experience various places.And the raising that requires along with cable work and the needs and the operating experience of urban construction, the defective that aforementioned tubes exposes itself gradually intrinsic be difficult to overcome:
(1) asbestos cement conduit: pollute and endanger the healthy of workmen because it has environment, various places were all expressly provided and are forbidden adopting in nearly 2 years.
(2) tremie: the tubing heaviness, installation labour intensity is big, cost is high, and urban road excavation open-assembly time is long, influences traffic.Inside pipe wall is coarse, and it is heavier etc. to wear cable.And because this pipe deadweight is heavier, if do not deal carefully with or place that soil property is relatively poor, cause uncoupling or sedimentation easily, when serious even cut off cable in the joint.
(3) pvc pipe: also there is low, not fire-retardant, easy aging, the shortcoming such as tubing is more crisp, useful life is short of intensity in it.
(4) steel pipe: be embedded in underground easy corrosion, installation labour intensity is big, and progress is slow, and is jagged, careless meeting scratch cable when wearing cable, and it, needs through special processing to prevent to produce eddy current when laying single-phase cable owing to be magnetic material.
Summary of the invention:
The object of the present invention is to provide a kind of intensity height, inner wall smooth, flexibility arranged, physique is light, the cable protection pipe and the production method thereof of long service life.
The object of the present invention is achieved like this: a kind of organic fire-resisting cable-protecting composite GRP pipe; the employing high strength glass fiber is a reinforcing material; by certain proportioning unsaturated polyester resin, antimonous oxide, cobalt iso-octoate and cyclohexanone are made epoxy glue; by soaking into, twine, roll, solidify composite molding in advance, its proportioning is:

Production method of the present invention is:
A) prepare unsaturated polyester resin earlier
Propylene glycol, ethylene glycol, diethylene glycol, phthalic anhydride, cis-butenedioic anhydride, quinhydrones, paraffin and aphthenic acids ketone are dropped in the reactor in proportion,, make unsaturated polyester (UP) 150～205 ℃ of reactions 10-12 hour;
Styrene is placed in the dilution still, put into above-mentioned unsaturated polyester (UP), make unsaturated polyester resin, the dilution temperature is controlled at 85-95 ℃
B) make epoxy glue
The above-mentioned unsaturated polyester resin input for preparing is in harmonious proportion in the bucket, adds antimonous oxide and mix well, add cobalt iso-octoate, that cyclohexanone is made epoxy glue is stand-by;
C) make composite glass fiber reinforced protection tube
Glass fibre is cut into certain size as required, immerses epoxy glue and soak in advance, patrix twines, roll, solidify, generate heat that to put the peak, move back temperature be that the protection tube semi-finished product are made in the demoulding to 20-30 ℃, promptly makes finished product again after cutting, repairing.
The present invention has following advantage:
1, intensity height.Can directly be embedded under the runway, need not to build the concrete protective pipe;
2, inner wall smooth, coefficient of friction is little, and it is gently sliding to wear cable, not the easy damaged cable;
3, tubing has flexibility, can keep out the destruction that foundation settlement causes.
4, physique is light, and installation is simple and convenient, reduces the installation cost.
5, good insulating, corrosion-resistant, ageing-resistant, long service life.
6, non magnetic, even, also need not to add special processing when laying single-phase cable.
