Problems solved by technology

[0007] (3) Poor temperature resistance, the cable at the plugged part is in a state of heating for a long time, which is easy to cause material aging and reduction and loss of structural strength, and affects the integrity of the fire-resistant and heat-insulated part of the plugged part
[0008] (4) The bonding ability decreases at high temperature or the charring strength is low, and the bonding ability between heat insulating agents is likely to decrease at high temperature
When the flame is too large or there is an impact flame such as deflagration or explosion, it is easy to cause thermal erosion behaviors such as scattering and falling off under the action of impact heat flow, resulting in the loss of fire-resistant and heat-insulating capabilities of the fire-resistant module and loss of protection.
[0009] (5) The airtightness of the existing fire-blocking module is poor. When used in oil and gas exploration, petroleum refining, oil and gas stations and other industries, it cannot block the diffusion of flammable gases and cannot play an effective role in explosion-proof insulation.
[0010] (6) The existing fire-blocking module has high rigidity and no damping and shock-absorbing function. When it is used in the vibration environment such as rail transit and the hole is deformed, it is very easy to cause problems such as slag, cracks, cracks, and fragmentation, which seriously affect its performance. Integral performance of fire resistance and heat insulation

Description

technical field [0001] The invention relates to the technical field of fireproof sealing, in particular to a fireproof and explosion-proof insulating sealing material and a fireproof module thereof. Background technique [0002] The traditional fire-blocking module is made of adhesive and inorganic filler, which has the advantages of light weight, convenient installation and maintenance, good heat insulation and fire-blocking effect, and high cost performance. In petrochemical and other fields, it is used to block various penetrations, such as various openings formed when cables, air pipes, oil pipes, and air pipes pass through walls (warehouses) and floors (A) boards, and fireproof separation of cable bridges. In order to prevent the fire from spreading through these openings and gaps. [0003] Most of the materials involved in petrochemical plants are flammable and explosive hydrocarbon liquids and gases. Once leaked, vapor cloud explosion may occur, which will cause grea...
