Fire Proof Seal Bonding Properties And Aging Resistance

Sep 30, 2017

Fire Proof Seal is a kind of room temperature vulcanized silicone rubber, which is made of terminal hydroxyl polydimethylsiloxane as the main raw material, has excellent aging resistance and mechanical properties, and has good resistance to most building materials Of the bonding performance, in the national economy, especially in the construction of the curtain wall has a wide range of applications. With the development of high-rise curtain wall, the function of the sealant is not only limited to excellent bonding performance and aging resistance.

Ordinary Fire Proof Seal as the main raw material 107 base rubber in the 200-300 degrees Celsius can be burned, from a certain point of view are combustible items, and later the major manufacturers have introduced flame retardant sealant to solve the ordinary Fire Proof Seal burning Problem, flame retardant sealant used in the need to suppress the combustion of the building area. Products to meet the GB / T 24267-2009 building flame retardant sealant standard. Qualified flame retardant sealant can be done from the fire self-extinguishing,Fire Proof Seal that is no longer imposed the case of flame sealant to stop burning. Nevertheless, the flame retardant sealant in the continued flame burning will eventually be the same as the ordinary sealant ashes,Fire Proof Seal loss of blocking effect. In the current fire field more and more emphasis on fire conditions to maintain the integrity of the building components in the environment is clearly not meet the requirements. So the flame retardant sealant can not be used as a fire sealant.

It not only has the flame retardant sealant self-extinguishing flame retardant ability, but also in the high temperature that is not the case of fire ashing, no powder, ceramic occurs. Continue to maintain the sealant sealing effect,Fire Proof Seal effectively maintaining the integrity of building components. Prevent cigarettes

The most important function of the fire sealant used in the construction field is to emphasize the ability to maintain the integrity of building components in case of fire.

In the event of fire, the fire sealant with the surrounding temperature rise colloid gradually hardened and ceramicized, play a role in the closure of the gap,Fire Proof Seal to prevent the flame and smoke from the gap in the further spread.
