Abstract
A dual-component foaming polyurethane filler bag for blocking the protecting jacket of cable features that reactive hydrogen as component A and isocyanate containing-NCO group as component B are in partition mode loaded in same plastic bag to prevent them from flowing between chambers. When it is used, opening the partition can mix them together. The mixture is squeezing into mouth of protecting jacket of cable, where it is foamed and solidified to block it. Its advantages are safe transportation, easy in-situ operation and high block quality.
Description
The present invention is relevant with the cable laying construction material.
When the provided underground cable, cable is to pass pre-buried some underground sleeve pipes to contact piecemeal from missile silo to a missile silo, and sleeve pipe also plays the effect of protection cable.After cable is completed, comprise pre-buried sleeve pipe, all to block space between cable and sleeve pipe or sleeve opening at the sleeve pipe two ends, seal in whole system with blocking groundwater or gas and work the mischief, or prevent that the plague of rats from damaging cable.Existing method is to come shutoff with rubber seal or with materials such as some unsaturated-resins and cement, and the common defects of using these materials is that these materials can not expand, and often still has the space after the shutoff, and the then intensity that has is too big, is not easy to the cut construction again.In addition, because the space, job site is very little, it is very inconvenient to operate.
The object of the present invention is to provide in a kind of construction.Easy and simple to handle.The cable cover(ing) mouth of pipe of good sealing effect stops up the material of usefulness.
A kind of two component polyurethane that the present invention uses hard bubbles filler as plugging material, and it is by the A component that contains active hydrogen and contain-and two components of isocyanates (B component) of NCO group constitute.Here said A component is grouped into by following several one-tenth, and its composition content (weight %) is:
40.8-78.7 poly-(propylene oxide) ether, 0.8-4.1 the siliconefoam stabilizer, 1.6-8.2 it is selected from triethylene ethamine or N tertiary amine catalyst, N '-dimethyl cyclohexyl amine etc., 0.8-2.0 organotin catalysts, it is selected from stannous octoate or dibutyl tin laurate etc., 15.7-32.7 Freon-11, the fire retardant of 2.4-12.2, it is selected from the organic type fire retardant of halogen-containing element, as three-(2-chloropropyl-) phosphates, 2-methyl-methyl phosphorodithioate or three-(β-bromoethyl-) phosphate.
The B component is methyl diphenylene diisocyanate (MD1).The proportioning of A, B two components is A: B=1: 0.3-3.
Very fast generation foamed solidification reaction therefore in the prior art, was all taked to pack respectively separately to this bi-component glue after this class bi-component glue mixed, and on-the-spot allotment is fast used immediately during application.But for the cable laying construction,, can't after ground is deployed, deliver to the down-hole again and use, use very difficult in the allotment of scene, down-hole because underground activities well space is very little.In addition, on-the-spot allotment is because allotment personnel's technological disparity also can be brought construction quality difference to construction, so use very inconvenient.
Key of the present invention is two liquid components of this two group hard polyurethane foam fillers, and insulation package constitutes a kind of two component polyurethane filler cartridge bag that hard bubbles in a polybag in proportion.The structure of the isolated packaging bag of this bi-component is shown in accompanying drawing one.An end of a sealed plastic bag have one with polybag heat seal all-in-one-piece duroplasts mouth, the mouth mouth seals with movable cork, card has a clamp bar on the outer wall of polybag.Clamp bar is separated into two separate chamber to polybag on the folder, makes that the liquid in the chamber can not circulate between chamber.In two chambers, be filled with two liquid components of hard polyurethane foam filler respectively.So just obtain the two component polyurethane of the present invention filler cartridge bag that hard bubbles.
During use, take off clamp bar, two liquid components mix, and rub and the shaking ladle pack with hand, make it mix rapidly.Open the package then stopper on the plastics mouth with hand push-through packs bag, is extruded filler of the present invention from bag, inject the gap of underground cable and sleeve pipe.Sleeve opening is sealed in the very fast expansion of mixed liquor, curing.In construction in order to prevent mixed liquor trickling, should be in the slit of sleeve pipe earlier beyond the Great Wall some soft or packing ring, block with a backplate again in the outside, so just can be confined to the two component polyurethane rigid foam plastic of filling in the certain limit.Whole operation just can once be finished in very short time.
Further specify the hard bubble manufacture method of liquid filling agent cartridge bag of two component polyurethane of the present invention with a concrete instance more below,
Fig. 1 is the schematic diagram of cartridge bag of the present invention.
As shown in Figure 1, make a polybag with plastic film, earlier the A component that the contains active hydrogen polybag of packing into, clamp bar on the card (3), this moment, the liquid of A component was encapsulated in the chamber (1), poured in the polybag on clamp bar to contain-the B component of NCO isocyanates again.Seal the plastics sack then, the B component just is encapsulated in the polybag chamber (2), and the liquid in this moment two chambers is isolated fully.During use, isolate clamp bar (3) as long as open, two parts liquid can mix, react.
The invention has the advantages that polyurethane rigid foam plastic has expansive force, can in the slit, expand that choke all slits, shutoff is tight.And this material ageing-resistant performance is good, under wet condition, does not go mouldy, and does not corrode, and anti-aqueous vapor good penetrability has the good effect of resisting to Acidity of Aikalinity sewage.The tables of data of table one and table two is understood the premium properties of this polyurethane rigid foam plastic.
Table 1 polyurethane rigid foam plastic performance density: 10-80kg/m
3. compressive strength: 0.1-0.5MPa.Bending strength: 0.2-0.8MPa. Applicable temperature :-90 ℃～110 ℃.Water absorption rate (72 hours volume change % of water logging) is less than 0.3%, anti-flammability: from fiery 1-3 second from putting out.

This rigid foam plugging effect is good, and its hardness and not very big, pre-buried underground cable protecting tube seals unlatching conveniently with it, is convenient to cable construction and maintenance.
This two component polyurethane liquid filling agent of hard bubbling simultaneously, the present invention isolates can to it in same polybag in proportion, blocks with an isolation clamp bar between two components.All very safe in transportation, in storing, as long as take off the isolation clamp bar during construction, can use, needn't allocate temporarily.Can both guarantee construction quality at the down-hole direct control, and be very easy to workman's operation.Particularly in narrow missile silo, construct.Use and seem convenient especially.
Enumerate the hard bubble Formulation Example of liquid filling agent of several two component polyurethanes below again.The invention will be further described, certainly, is not confined in these several examples.
