Development of led-curable intumescent polymer coatings for fire protection of building constructions

Introduction. The authors claim to have originally invented and introduced structural curve-following intumescent fire protection not only for cabling, but also for civil structures of investment construction projects (also those of buildings and facilities of the oil&gas complex since the operation of the structures is possible also in the maritime and the Arctic climate areas). The fire-protection is roll material with structural reinforcement capable of 3D-swelling at a thermal shock.Statement of method. Tests have been conducted of retained operability of a cable line in a fire (as per GOST R 533162009) and of the fire-protection efficiency for a cable (as per GOST R 53311–2009). A magnitude 9 seismic impact as per MSK-64 was modeled. To determine the fir-resistance ratings, the fire-protection net was wrapped around columns and beams, as per GOST 30247.1–1994. A check of the fire-protection efficiency of the net (as per GOST 53295–2009) and a thermal analysis of the coating (as per GOST R 53293–2009) were executed.Results and discussion. In the course of the standard tests, the following fire-protection net parameters were obtained: fire-protection efficiency — 15, 45 and 60 min; fire-resistance ratings of structures (beam) with the fire-protection net R15, R45 and R60; seismic resistance at least magnitude 9 as per MSK; category 1 as per GOST 15150–69 (HL, UHL, Т, ОМ climate designs, open grounds in the specified macro-climatic areas), allowing for retained operation properties of the fire-protection net in Arctic climate within at least 10 years; possibility of dry installation within a temperature range –60...90 °С at 100 % humidity.Conclusions. A range of intumescent structural curve-following fire-protection materials for different civil structures (also for light thin-wall steel structures (LTWSS)) and cable lines in form of a frost- and oil-resistant polymer compound on non-flammable net base has been developed, certified and launched into serial manufacturing.
