COMPOSITION FOR HEAT-RESISTANT FOAM MATERIAL Russian patent published in 2017 - IPC C08J9/32 C08L83/00 C04B38/00 

FIELD: chemistry.

SUBSTANCE: composition for a heat-resistant foam material is described, comprising a silicon-containing binder, hollow ceramic microspheres (cenospheres), and a fibrous filler, in which in order to increase the mechanical strength and heat resistance of the foam, as a silicone-containing binder the composition contains, wt %: 10% polycarbosilane solution in xylene, as hollow ceramic microspheres - cenospheres produced by flotation treatment of smoke emissions from a solid-fuel thermal power plant, the composition of which contains SiO₂, Al₂O₃, CaO, MgO, Na₂O, Fe₂O₃, as a fibrous filler - quartz fibers with the following ratio of the composition components, wt %: the said silicon-containing binder 13.0-76.9, hollow ceramic microspheres (cenospheres) 21.0-66.2, quartz fibers 2.1-20.8.

EFFECT: foam material is produced with increased heat resistance and strength.
