“…The further temperature rise causes the slow thermal decomposition of clay and formation of strongly protonated catalytic spaces on its surface that catalyze the formation of stable and fire retardant charring (the last exothermic peak shifts from 530 C to 560 C and the total weight loss is −90.10 wt%). 2,12,13,18,21,22,28,30,46 Peaks for the epoxy resin with the addition of titanium dioxide practically coincide with the thermogram peaks for the pure epoxy resin (Figure 8). A significant difference is only in the case of a total weight loss.…”

“…The risk of fire should be minimized by the use of flame retardant and burning rate reducing materials. [1][2][3] Special attention should be paid to selected halogen, phosphorous and nitrogen compounds, as well as to inorganic compounds of certain metals (e.g., TiO 2 , Al(OH) 3 , Fe 2 O 3 nanoparticles). [1][2][3][4] Various flame retardants reveal diverse mechanisms of action.…”

The article presents results of the research on the influence of graphite/kaolin and graphite/titanium oxide systems on thermal properties, intumescence degree and the integrity of the structure of intumescent protective films based on epoxy resins for steel. The TG/DTG/DSC analysis showed that graphite/kaolin system shifted the decomposition reaction of epoxy resin towards higher temperatures, even by about 30 C. Fire endurance tests and the SEM analysis confirmed these results because more thermally resistant (T 500 C reached after 37.5 min for 1.1 coating thickness), swollen (about 20 times) and homogeneous coatings were obtained. The presented results suggest that ceramic fire retardants can successfully cooperate with organic components in intumescent protective coatings for steel elements.

Purpose. To develop an algorithm for calculating the problem of determining the nonstationary temperature field through the thickness of a multilayered structure, taking into account changes in the thermophysical characteristics and geometric dimensions (fluctuations) of the applied fire protection coating. Methodology. Application of the direct method for solving the differential equation of heat conduction using the method of reduction, the concept of quasiderivatives, the method of separation of variables and the modified method of eigenfunctions of Fourier. findings. An algorithm for determining the nonstationary temperature field in a multilayered flat structure is proposed, taking into account changes in the thermophysical characteristics and geometric dimensions (bursting expansion process) of the fire protection coating. This is achieved by solving a sequence of two tasks (the temperature field before the swelling and after the swell ing of the coating). originality. For the first time, using the direct method, in solving the problem of nonstationary heat conductivity, an algo rithm for determining the temperature field in multilayer elements with variable thickness of a layer on the example of building structures with flame retardant systems based on intumescent coatings is proposed. Practical value. Further, this approach can be implemented for approximation of solutions of heat conduction problems and it will allow catalyzing studies on fire retardant properties of intumescent coatings.

This study investigated the effects of wolframite on the fire resistance and adhesion strength of intumescent fire‐retardant coating (IFRC) using a siloxane‐modified epoxy binder. The modification of bisphenol A epoxy was confirmed via Hydrogen‐Nuclear Magnetic Resonance Analysis. The IFRC samples were developed with wolframite (0.25–2.0 wt%) and evaluated for Thermogravimetric analysis (TGA), fire resistance test, furnace fire test for char expansion, morphology and chemical composition, adhesion test and water immersion test. This study identified a coating formulation containing 2.0 wt% of wolframite that showed 57.2% improvement in the residual weight, substrate temperature of 176.7°C and produced a compact char. Field Emission Scanning Electron Microscopy showed that the addition of wolframite reduced pore size thereby increasing the char strength. X‐ray diffraction identified iron neodymium compounds in the char layers, which lowered the pore size resulting in lower substrate temperature. X‐ray photoelectron spectroscopy indicated that the antioxidant capability and the carbon content were increased by 6.9% and 50.3% respectively. The adhesion strength was reduced, however, was within the industrial standards of 2.07 MPa. The water immersion test showed a maximum 66.7% reduction (WF2.0) in the water permeation through the coating.
