CERAMIC COMPOSITE MATERIALS FOR FACING WALLS, CAPABLE OF REFLECTING INFRARED RADIATION Russian patent published in 2011 - IPC C09D183/00 C08K3/22 C08K5/5415 C08J7/04 B05D7/04 D21H19/32 

FIELD: chemistry.

SUBSTANCE: method of coating substrates comprises the following steps: a) preparing the substrate, b) depositing a composition onto at least one side of the substrate, the composition containing an inorganic compound which contains at least one metal and/or semimetal selected from a group comprising Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, Tl, Si, Ge, Sn, Zn, Pb, Sb, Bi or mixtures thereof, and at least one element selected from a group comprising Te, Se, S, O, Sb, As, P, N, C, Ga or mixtures thereof, c) drying the composition deposited at step b), d) applying at least one coating onto at least one side of the substrate onto which the composition was deposited at step b), wherein the coating contains silane of general formula (Z¹)Si(OR)₃, where Z¹ is R, OR or Gly (Gly=3-glycidyloxypropyl), and R is an alkyl residue with 1-18 carbon atoms, and R can be identical or different, oxide particles selected from a group comprising oxides of Ti, Si, Zr, Al, Y, Sn, Zn, Ce or mixtures thereof, and an initiator, wherein the coating preferably contains 3-aminopropyl-trimethoxysilane and/or 3-aminopropyl-triethoxysilane and/or N-2-aminoethyl-3-aminopropyl-trimethoxysilane, and e) drying the coating applied at step d). The composition at step b) and/or the coating at step d) contain at least one pigment which reflects infrared radiation, and said pigment has a core coated by an electroconductive layer which contains tin oxides and/or titanium oxides. The invention also discloses use of the coated substrate obtained using the disclosed method as wall-paper.

EFFECT: method enables cheap production of a coated substrate capable of reflecting infrared radiation, and simplifies facing buildings.
