A fire-retardant coating material including a fluid intumescent base material having a foaming agent, a blowing agent, a charring agent, a binding agent, a solvent, and a pigment. The coating material further includes a flame spread reduction agent; refractor fibers dispersed in the fluid intumescent base material; an oxidation reduction agent; a thermal transmission reduction agent; a stabilizer and volatile organic reduction component; a mechanical enhancer component for physical impact resistance and adhesion; a water-resistance agent; and an elasticity agent to increase resistance to cracking and shrinking, and to improve ease of spraying.
A fire, heat and backdraft protection system is described for protecting firefighters in all types of fires. The protection system includes a composite laminate structure having a plurality of layers for the protection of firefighters who are exposed to high temperatures of 2200.degree. F. for 30 minutes in duration. The plurality of layers includes an outer first layer, an inner second layer and an inner third layer. The outer first layer is a fiberglass textile having an intumescent coating resistant to heat, water and impact. The inner second layer is a metal foil layer for reflecting heat and eliminates the convection transfer of heat. The inner third layer is a low conductivity refractory blanket for reducing the transmission of heat. The inner fourth layer is a metal foil layer for reflecting heat and eliminates the convection transfer of heat.
A composite conduit comprising an inner layer of fibrous material impregnated with a corrosion resistant resin and a fire resistant outer layer thereon, the outer layer comprising a fibrous material impregnated with an effective amount of calcium sulfate.
A halogen-free fire retarding plastic coating composition, includes a binding fraction that has a limited oxygen index (LOI) of at least 25% and an intumescent agent that has a thermodegradable strong acid compound and a polyhydric carbon compound, with a weight ratio of the strong acid compound to the polyhydric compound of between 1.5 and 2.
A process for an aqueous liquid flame retardant and fire quenching and extinguishing product for various and diverse materials with wide ranging chemical affinity. Preparations are safe, non-toxic, for professional and household use, in a stable colloidal dispersion. Mixtures include a base comprised a source of phosphoric acid, a charring agent, and a blowing agent. Products can be used with conventional manual and household spraying means, and have long shelf life and stability.
A process to render flame- and fireproof surfaces and materials and inhibit the spread of fire on materials of various, and diverse, chemical nature and affinity, using one basic fire and flame retardant material, with wide ranging chemical affinity. Preparations are non toxic, for professional and household use, in a stable colloidal dispersion. Intumescent mixtures include a base comprising a source of phosphoric acid, a charring agent and a blowing agent, further comprising flame spread reduction materials, thermal resistance enhancers, thermal transmission reduction and refractory, elasticity, water resistant materials, and combinations thereof. Preparations are further treated with activated bipolar chemicals to change their chemical affinity, to make them applicable to synthetic and metallic substrates and surfaces as well. to be used on buidling materials, furniture, home furnishings, rubber, electric wires, walls, toys, etc.
