Method for obtaining foamed organosilicon compositions

Method for obtaining the foamed organosilicon compositions, involving mixing of organosiloxane rubber (OR), organosilicon joining agent (JA) and modifier (M). Agents acting like (OR) are represented by polyorganosiloxane block-copolymers having formula as follows: {[R1SiO1.5]a[R2(OH)SiO]b, [R3R4SiO]c}n, where: R1R2R3R4 are aliphatic, aromatic radicals having from 1 to 6 atoms carbon; n is an integer from 30 to 360; c=1; a is selected from the 0.019-3.760 interval; b is selected from the 0.008-0.240 interval; or the mixture of the above block-copolymer with the "alpha", "omega"-dihydroxypolydiorganosiloxane in the ratio of (0.05-0.5):1, respectively; while the individual compositions or mixtures of polyorganohydridesiloxanes act as (JA), having general formula as follows: R3SiO[R1(H)SiO]m-[R2SiO]nSiR3, or at least one substance from the compositions having general formula as follows: RSiX3, where: R=alkyl radical having from 1 to 6 atoms carbon, CH2=CH-, X:-ON=C(CH3)2, -OC(O)-CH3, and amines are used as (M), having general formula as follows: R1R2N-(CH2)n-Si(OR3)3, or the mixture of sodium bicarbonate with zinc oxide, or non-organic compound of cobalt with 34% cobalt content, with the proviso of mass fraction ratio of (OR) mixed components as follows: (OR)=100; (JA)=from 2 to 15; (M)=from 2 to 22.
