The main way of flame retardant is to slow down the thermal decomposition, blocking the combustion process, the specific kinds of flame retardant ways are as follows.
1. Adding one or several kinds of substances to change the thermal decomposition behavior of rubber, so that the thermal decomposition temperature of the prepared rubber becomes higher, and reduce the flammable gas produced by decomposition.
2. The added substance can produce non-combustible gases when heated, or produce viscous substances that insulate O2, or absorb heat when heated, so that the three elements of combustion (combustible material, oxygen, and reaching the ignition point) cannot be met.
3. Adding substances that can capture HO- to interrupt the chain reaction and terminate the flame propagation.
4. Change the structure or nature of the rubber molecular chain to improve the thermal decomposition ability or make it self-flame retardant.
Due to the rubber and various additives have good compatibility, so add all kinds of flame retardant is still an important means of rubber flame retardant modification.
