RAW MIXTURE FOR HEAT-INSULATING MATERIALS Russian patent published in 2003 - IPC

FIELD: production of heat-insulating materials. SUBSTANCE: proposed mixture made on base of synthetic binder and organic filler is used for manufacture of light articles and structures for heat insulation. Proposed mixture contains latex used as organic binder; waste wool at length of fibers up to 16 mm and saw-dust of 2-2.5 mm fraction at 1:1 ratio are used as organic filler; mixture contains additionally water-repellent additive at the following relationship of components, mas. %: latex, 18- 39; waste wool, 40-30; saw-dust, 40-30; water-repellent additive, 2-1. Average density of material thus obtained ranges from 150-260 kg/cu.m at heat conductivity coefficient of 0.048-0.058 W/(m C). EFFECT: reduction of average density and heat conductivity of material. 1 tbl
