Certain questions of the fire protection of wooden structural materials, chipboard, and binding agents are examined. The mechanisms of chemical fire protection and the kinetic laws governing the process of thermal breakdown of modified specimens are clarified. On the basis of using the latest fire test methods, the combustion and thermal degradation regimes of wooden materials have been established. The advantages of polymeric fireproofing agents over low-molecular weight analogues are shown.

In this paper, the research program “Optimized use of intumescent coating systems on steel members” is presented. The aim of the project is to quantify the influence of space-enclosing elements on the thermal behavior of supporting steel members. Those elements partially result in a restrained expansion of the fire protection system. Experimental investigations on coated beams and columns directly connected to space-enclosing elements are presented. Additionally, numerical simulations are performed for temperature field calculations of steel elements with intumescent coating. As a new development, the numerical model takes into account the expansion process of the intumescent coating.

Various types of intumescent fire retardant coatings (IFRCs) have been used to protect the substrates exposed to fire. In current study, high temperature filler Wollastonite (W) filler was used to improve fire performance of intumescent fire retardant coating. The basic ingredients of the coating were ammonium poly-phosphate (APP) as acid source, expandable graphite (EG) as carbon source, melamine (MEL) as blowing agent in epoxy binder, boric acid as additive and hardener as curing agent. In this study a range of coating formulations were developed by using different weight percentages of Wollastonite filler. The coated steel substrate samples were tested for fire performance using Bunsen burner and char expansion was measured using furnace fire test. Composition of the char was determined by X-ray diffraction (XRD) technique. The char morphology was studied using field emission scanning electron microscopy (FESEM). Results showed that Intumescent coating with addition of Wollastonite filler enhanced anti-oxidation of the char. Presence of phosphorus, calcium and silicon in char layer further improved the thermal stability of char.

The objective of this research work was to study the thermal efficiency of intumescent fire retardant coating (IFRC) designed to protect structural steel in event of fire. IFRC has been effectively developed by using ammonium polyphosphate (APP), expandable graphite (EG), melamine (MEL), boric acid (BA), titanium oxide (TiO2), and bisphenol A BE-188 with polyamide amine H-2310 as curing agent. Six formulations were developed using different weight percentage (wt. %) of TiO2 and samples were tested for char expansion in furnace at 500°C for 2 h. Bunsen burner test was used to investigate the thermal performance of coating and its performance was compared by using thermal margin value. FESEM was used for char morphology. Char composition was analyzed by XRD and FTIR. Results showed that the coating with 4 wt. % of TiO2 provides better thermal insulation to the steel substrate.

This study investigates the effectiveness of halloysite nanotube as filler on improvement in thermal performance of epoxy based intumescent fire retardant coating. Several intumescent fire retardant formulations were developed with and without halloysite nanotube. The thermal performance and char morphology of Intumescent fire retardant formulations was studied. Bunsen burner (ASTM E-119) test revealed that incorporation of HNTs (1.5 wt. %) improved flame retardancy by reducing the temperature of steel substrate up to 99 °C when exposed to fire for 1 hour. This study also revealed the physical and chemical mechanisms of action of HNTs in the intumescent systems. Results showed that halloysite improved the growth of the intumescent shield and give better quality of char. HNT formed aluminosilicate network for the phosphocarbonaceous structure by chemical contacts with ammonium polyphosphate. These new chemical species enhanced thermal stabilization of the char at high temperature and offered good structural properties on micro and macro scale. This increased the mechanical strength of the shielding layer during burning and also enhanced the residual weight percentage after thermal degradation as shown in thermal gravimetrical curves.
