Problems solved by technology

[0003] 1. The fire limit is low, and it is difficult to meet the high difficulty requirements for fire prevention in the above fields;
[0004] 2. The existing fire and flame retardant system still mainly uses halogen, which mainly plays a role in the gas phase. Halogen is the chain terminator of the foam plugging material, which generates hydrogen halide and inhibits the combustion reaction. Although the effect is good, it is not environmentally friendly. The smoke density is high, and it will produce strong irritating and toxic gases when burning, endangering life safety

Description

technical field [0001] The invention relates to the technical field of fire-proof sealing materials, in particular to an environment-friendly foam plugging material with high efficiency and fire resistance. Background technique [0002] With the rapid development of my country's economic construction and the emergence of new building structures, industries such as petroleum, petrochemical, electric power, steel, and communications have brought new challenges to the field of fire blocking materials, which are currently widely used in buildings, structures, and building facilities. There are still the following problems in the fire blocking materials used in various through-holes and structural gaps in China: [0003] 1. The fire limit is low, and it is difficult to meet the difficult requirements for fire protection in the above fields; [0004] 2. The existing fire and flame retardant systems still mainly use halogen, which mainly plays a role in the gas phase. Halogen is th...
