The invention relates to heat insulating and water - proof material that protects, for example, steel (iron) pipes from heat loss.Known composition for heat and waterproof insulation of pipelines, comprising a polyisocyanate containing sorbed water, diethylene glycol, triethanolamine, silicone fluid, acetone, and mineral filler (SU 695965 And 08.11.1979).The lack of materials on a named basis, is a high density, leading to high thermal losses. The last disadvantage is partially solved in the known composition in the following ratio, wt.h.: The Polyisocyanate - 110-150 Diethylene Glycol 27.03.1996).However, the known technical solution is also not possible to get the required quality, because the presence of acetone leads to spontaneous foaming composition, which does not allow to obtain a material with a uniform structure.The composition of the proposed composition (EN 2121466 C1, 10.11.1998), allows to obtain a uniform structure and good strength in compression, but also does not provide the necessary level of heat loss, which is an indispensable requirement for underground laying insulated pipelines.The technical result of the proposed penopolimermineralnaya composition is to obtain products with improved thermal performance.This is achieved by the fact that in the composition the proposed composition contains components, the weight ratio which allows to obtain a three-layer system consisting of two compacted cortical layers (on the tube and the periphery of the insulation) and uniform structure of the middle insulating layer, and the design in General has good tensile strength in compression, and a middle insulation has a bulk density not exceeding 70 kg/m3that allows you to provide the necessary level of heat loss and gain and is, ostoja of MDI (component "B"), polyether, foaming agent, catalyst, stabilizer (component "A") and mineral filler (component C) in the following ratio, wt.h.: Component a is a mixture of polyethers, foaming agent, catalyst, stabilizer) - 25-29 Component "B" (polyisocyanate) - 40-49

Technical characteristics of the obtained samples of the proposed composite materials are presented in table 1.For insulating composition of these components can be mixed at various weight ratios of the components to achieve technical results of this invention, as evidenced by the examples in table 1, are given in comparison with insulating compositions with other volumetric masses.The ratio of the components shown in table 2 received in the insulating part 1 (component "A" - 25 wt.h., component "B" - 40 wt.h., component "C" - 80 wt.h.), in heat-insulating part 2 (component "A" - 27 wt.h., component "B" - 42 wt.h., component "C" - 85 h.), in the insulating part 3 (component "A" - 28 wt.h., component "B" - part 5 (component "A" - 40 wt.h., component "B" 70 wt.h., component "C" - 140 wt.h.)
Component "A" consists of:
polyethers of at least 75% of hardener;
a blowing agent is not less than 17% - soft freon;
catalyst is not less than 5% of triethanolamine;
stabilizer not less than 3% of silicone fluid.Component "B" is used as a binder, consists of MDI - 100%.Component "C" is used as a filler may consist of, for example, from andesite flour, dolomite powder, quartz sand - rest.To obtain these compounds on an industrial scale is possible using produced by domestic and foreign industry volumetric mixers, propeller type.A comparison of the claimed compounds with known shows that they meet the patentability requirements of "novelty" and "inventive step". As for the implementation of these compounds is possible using commonly used mixing equipment, they match the criterion "industrial applicability".
