Fire-protective coatings

Insulators or materials with low heat conduction are often used for fire protection coatings and thermal insulation. This thermal barrier prevents heat reaching and damaging structural steel and process vessels.

A mixture of ammonium chloride and borax was one of the treatments of cellulosic fabrics reported by Gay-Lussac in 1821. Due to its low dehydration temperature and water solubility, sodium borates are only used as flame retardants in cellulose insulation (ground-up newspaper— see Sections 9.2.1.2 and 9.2.2.1), wood timber, textiles, urethane foam, and coatings. For example, a mixture of urethane (100 parts), borax (100 phr), and perlite (30phr) was claimed to provide flame-retardant urethane foam.8 Borax in conjunction with boric oxide, silica, ammonium chloride, and APB as ceramizing additives and volume builders, are claimed in a fire-protection coating based on polybutadiene and silicone microemulsion.9 Using a modified DIN 4102 test, the chipboard with the coating showed a loss of mass less than 1% and there was no pyrolysis of the wood sample.

Decease in the mass decrease of fire-protective coatings at exposure over the open flame of a gas burner for 2 minutes at a temperature of 200°C and a flame height of 15 cm was measured. The charring time of wood samples tested over a flame at a temperature of 950°C-1050°C was measured. These conditions simulate fire conditions that cause inflammation of a wood substrate.
