Abstract

The invention provides a polymer fire-proof and moisture-proof sealing agent and its preparation method and application, and relates to the technical field of fire-proof and moisture-proof sealing materials. The polymer fire-proof and moisture-proof sealing agent includes the following raw materials in parts by mass: vinyl 80-120 parts of silicone oil, 0.3-0.5 parts of the first silane coupling agent, 0.3-1.2 parts of the second silane coupling agent, 2-5 parts of platinum complex and 1-3 parts of hydrogen-containing silicone oil solve the problem of traditional plugging The material is easy to crack, the fireproof and moistureproof effect is poor, the fluidity is weak, the leveling effect is poor, and the technical problems of secondary construction are difficult. The polymer fireproof and moistureproof sealing agent provided by the invention not only has excellent fireproofness, moistureproofness and fluidity And water repellency, it can block the cable gap in all directions without dead ends and achieve excellent fireproof, moistureproof and small animal effects, and it has no corrosion to contact cables and box materials, has certain flexibility, and is easy for secondary construction , the weather resistance will remain unchanged for 20 years, and the blocked parts can be used again. The application market is huge and the prospect is good.

Description

technical field [0001] The invention relates to the technical field of fire-proof and moisture-proof plugging materials, in particular to a polymer fire-proof and moisture-proof plugging agent and its preparation method and application. Background technique [0002] As the use of power boxes becomes more and more widespread, the safety of power boxes is particularly important, especially in terms of fire, moisture, corrosion and corrosion, sealing materials with excellent performance are needed to improve the safety performance and service life of power boxes. At present, fireproof mud, fireproof sandbags, cement and polyester polymer materials are mostly used for sealing power boxes and secondary cables at substation construction sites. The gap sealing performance is poor and cannot be reused. With the increase of the primary equipment of the substation, if the above sealing materials are used for power sealing, it will take a lot of manpower and material resources to compl...
