Can guanidine carbonate play a flame retardant role?

Carbonate guanidine can exhibit a certain degree of flame retardancy under specific conditions. As a nitrogen-containing compound, it can release ammonia and other nitrogen-containing compounds, which can dilute and inert the flame, thereby reducing the rate of combustion reaction and heat release. This flame retardant mechanism is known as the nitrogen effect.

However, it is important to note that the flame retardant effect of carbonate guanidine is relatively weak and is generally not sufficient when used alone. In practical applications, it is often combined with other flame retardants or additives to enhance the flame retardant performance. For example, carbonate guanidine can be combined with ammonium phosphate to form a composite flame retardant system, providing better flame retardancy.

Additionally, the flame retardant performance is influenced by various factors, including the concentration of carbonate guanidine, the method of incorporation, and the nature of the material substrate. Therefore, specific experiments and testing are necessary to determine the flame retardant effect of carbonate guanidine in a particular system and to compare and evaluate it against relevant standards and requirements.

In summary, carbonate guanidine can exhibit a certain degree of flame retardancy under specific conditions, but it typically needs to be used in combination with other flame retardants to enhance the overall flame retardant performance.
