Problems solved by technology

[0004] However, the existing fire-proof sealing module has poor weather resistance, and the product is prone to failure after being exposed to wind, sun, and moisture. Under normal conditions, stable performance cannot be guaranteed, and it is difficult to play a fire-proof role in the event of a fire.
Moreover, the existing fireproof plugging module is not easy to cut, and it is easy to drop slag when cutting

Abstract

The invention provides a fireproof plugging module and a preparation method thereof. The fireproof plugging module comprises 30 to 45 parts of compound polyether polyol, 5 to 15 parts of a flame retardant, 5 to 15 parts of low-temperature expanded graphite, 3 to 5 parts of a moisture-proof agent, 0.2 to 0.4 part of a catalyst, 15 to 25 parts of a curing agent, 0.1 to 0.3 part of a plasticizer and0.2 to 0.5 part of deionized water. The fireproof blocking module is good in weather resistance, capable of expanding at low temperature, easier to cut and free of slag falling during cutting.

Description

technical field [0001] The invention relates to the technical field of fireproof sealing materials, in particular to a fireproof sealing module and a preparation method thereof. Background technique [0002] Fireproof sealing materials are mainly used to seal various penetrations, such as various openings formed when cables, air pipes, oil pipes, and air pipes pass through walls and floors, as well as fireproof separation of cable bridges, so as to prevent fire from spreading through these openings and gaps , has excellent fire protection function and is easy to replace.
