Research and Analysis of Intumescent Flame Retardant Synergist

Jan 09, 2019

Intumescent flame retardant synergists contain a composition of substances with different compositions. The so-called synergistic effect means that the combined effect of two or more additives is better than that of a single component. The flame retardant synergistic effect is mainly a charcoal synergist and a catalytic charcoal synergist in a coagulation camera based on intumescent flame retardant.


In fact, people currently do not fully understand the synergistic mechanism in the flame retardant system, but have a relatively consistent view on some commonly used flame retardant synergists. These synergists prevent combustion by capturing free radicals in the gas phase; on the other hand, they promote the surface of the material in the condensed phase to form a dense carbon layer, which acts to insulate, oxygen, and prevent flames. Further dissemination.


As a new type of flame retardant synergist product, it mainly includes three components: acid source, gas source and carbon source. A major disadvantage of the intumescent flame retardant is that the amount of addition is relatively large, and the flame retardant efficiency is not high. Therefore, it is necessary to improve its flame retardant efficiency, and it has been found that it can be achieved by adding some other components.www.china-zhufengchem.com
