INSULATING DOUBLE-GLASED WINDOW, HAVING LOW-GAS PERMEABILITY SEALING COMPOUND CURABLE AT ROOM TEMPERATURE Russian patent published in 2012 - IPC C08L83/04 C09K3/10 E06B3/66 C03C27/10 

FIELD: chemistry.

SUBSTANCE: insulating double-glased window has at least two glass sheets spaced apart, a low thermal conductivity gas in between and a gas sealing element containing a curable sealing compound. The sealing compound consists of a) polydiorganosiloxane, which is permeable to said gas and the polydiorganosiloxane has a silanol end, having the following formula: M_aD_bD'_c, in which a=2, b≥1, c equals zero or a positive whole number, M=(HO)_3-x-yR¹ _xR² _ySiO_1/2, in which x=0, 1 or 2, and y=0 or 1, provided that (x+y)≤2, R¹ and R² denote univalent C₁-C₆₀ hydrocarbon radicals; D=R³R⁴SiO_1/2, in which R³ and R⁴ denote univalent C₁-C₆₀ hydrocarbon radicals; D'=R⁵R⁶SiO_2/2, in which R⁵ and R⁶ are independently selected from univalent C₁-C₆₀ hydrocarbon radicals; b) at least one polymer which is at least less permeable to said gas than the polydiorganosiloxane polymer; c) a cross-linking agent; and d) a cross-linking catalyst.

EFFECT: obtaining insulating double-glased window with improved heat insulation stability and longer service life.
