Embodiment 1

[0039] The cable duct sealing agent consists of two components, A and B, in parts by weight, and the raw materials are as follows:

[0040] A component

[0041]

[0042] B component

[0043] Diphenylmethane diisocyanate (MDI) 0.507kg

[0044] Polyphenyl polymethylene polyisocyanate (PAPI) 0.045kg

[0045] Prepare A and B two components into W material and B material respectively, and its preparation method is:

[0046] (1) Preparation of material W: weigh component A in parts by weight and stir evenly in a stainless steel reaction kettle. The stirring speed is 3000~4000n / min; the stirring time is 1~2min. Fill W material in the plastic bag that is provided with discharge port and seal and preserve.

[0047] (2) Preparation of material B: weigh component B in parts by weight and stir evenly in a stainless steel reaction kettle. The stirring speed is 3000~4000n / min; the stirring time is 1~2min. Fill material B in a plastic bag with a discharge port and keep it sealed. ...

Embodiment 2

[0058] The cable duct sealing agent consists of two components, A and B, in parts by weight, and the raw materials are as follows:

[0059] A component

[0060]

[0061] B component

[0062] Diphenylmethane diisocyanate (MDI) 0.5432kg

[0063] Polyphenylpolymethylene polyisocyanate (PAPI) 0.048kg

[0064] The method of preparation and use of the plugging agent in Example 2 is basically the same as in Example 1, except that the two components A and B are mixed together at a mass ratio of 100:70. The physical and chemical properties of the plugging agent obtained in Example 2 are shown in Table 2.

Abstract

The invention discloses a cable pipe sealing agent and a using method thereof. The cable pipe sealing agent includes two components A and B, and the A component includes 70-80 parts by weight of dihydroxy polyether; chain extender 2 to 4 parts; 5 to 8 parts of crosslinking agent; 1 to 1.5 parts of silicone surfactant; 1.5 to 2 parts of water and 1 to 1.5 parts of amine trimerization catalyst; component B consists of diphenylmethane diisocyanate ( MDI) and polyphenyl polymethylene polyisocyanate (PAPI) are mixed in a mass ratio of 90: (8 to 10); the proportion of the two components of A and B is calculated as: 100: (70-80). The present invention adopts the expandable cable pipe sealing agent to block the cable pipe in sections, which integrates waterproof, sealing and anti-theft, and can achieve multiple effects of permanent sealing, corrosion resistance, protection against rodents and ants.

Description

technical field [0001] The invention relates to the technical field of power cable installation, in particular to a cable pipe sealing agent and a method for using the same. Background technique [0002] As the requirements for power facilities become more and more standardized, the level requirements for the sealing of cable duct holes are also getting higher and higher. The power supply design and operation departments have clear requirements for the sealing of cable duct holes. It can be seen that it is extremely important to do a good job of sealing the cable pipe hole, which is an important guarantee for the safe operation of power supply facilities. [0003] At present, there are many materials and structures for cable pipe hole sealing. The existing sealing materials include fireproof mud, styrofoam, rubber, cement, etc., and the sealing structures include rubber pipe sealers, pipe sealing modules, and flanged pipe seals. Plugs, inflatable pipe plugging airbags, etc....
