Heat Insulating Material on the Basis of Thermo-Reactive Resins and Waste of Heat Power Industry

Foamed heat insulating materials notable for their technical and operation characteristics have been obtained. The fly ashes of OAO “Irkutskenergo” of different chemical compositions is used as fillers of polymeric compositions; modified phenol-formaldehyde resins of different brands are used as a binder. The maximum content of fly ash in the material is 55 wt.%. Structural features of the foam material are considered. When the content of the filler is over 30%, pseudo-crystallites of various shapes with round and oval pores of different sizes are observed. Depending on the content of fly ash in the composition, the diameter of cells changes: when the filling is 30%, the diameter of cells is 2–200 mkm, 35% – 5–300 mkm, 40% – 5–400 mkm. The results show that the developed heat insulating material has following characteristics of combustibility – G1, V2, D1, T1 that makes it possible to say that it can be safely used as a contemporary insulation material. Results of the study allow us to draw conclusions about prospects of using this material in building industry.
