Abstract: The research, by means of thermal analysis, on the pyrolytic reaction of fire coatings added with LL fire retardant is presented in this paper. It is also introduced that all the characteristic parameters of the pyrolytic reaction can be reproduced in accordance with the TG curve and that the apparent activation energy of the pyrolytic reaction can be obtained according to the dynamics of pyrolytic reaction of fire coatings.The relationship between the properties of heat absorption and foamed carbonization layer during the reaction and the properties of fire retardancy and heat insulation of fire coatings are analyzed in order to provide information for the development of intumescent fire coatings of high efficiency and superior quality in the future.
