Abstract:

Fires are unsolved problems of world civilization. No less dangerous are the cases of population chocking and poisoning by fire, which is caused, mainly, by combustion products as well as by toxicity of using safety precautions. Therefore, the world faces the problem of fire localization, liquidation and development of such safety precautions, which will provide inhibition of burning of matter in the zone of inflammation and decrease of toxic materials emission. The use of fire-extinguishing and fire-protective means, occur topical among the mentioned measures. Unfortunately, the statistics confirms, that traditional fire-extinguishing and fire-protective materials, are sufficiently expensive, not universal, neither eco-safe and less efficient. Therefore, at present one of the most important problems is the elaboration of non-halogen, eco-safe fire-extinguishing and fire-protective materials. In our work we describe the ways of development of technology for production of novel, halogen-free, eco-safe, highly efficient, universal fire-extinguishing powders based on local mineral raw materials and elaboration of new types, eco-safe fire-protective materials on the basis of such fire-extinguishing powders. The technology for production of these materials differs from the serial production technology. Fire-extinguishing powders we made by mechanical blending of local mineral raw materials, do not require modification with expensive, halogen-inclusive hydrofobizative additives, what makes the extinguishing materials far cheaper than imported analogues. Experimental data confirm that such powders are characterized by high inhibition properties and fire-extinguishing ability. Here it should be noted, that obtained powders similarly to inert flame retardants, don�??t participate in the process of polymer preparation, and in contrast to them are characterized by high operating properties. Therefore, fire-extinguishing powders of our preparation in fire-protective materials are functioning, as efficient flame retardants.Thus, fire-protective materials are manufactured only by mechanical mixing of binders- Polyurethane resins and fillers- High-dispersed fire-extinguishing powders of our preparation, does not need addition of expensive flame retardants. Therefore such fire-protective materials are eco-safe, very effective and far cheaper than imported analogues.
