COMPOSITION FOR APPLYING HEAT INSULATING COATING AND PREPARATION METHOD THEREOF Russian patent published in 2011 - IPC C09D5/00 

FIELD: chemistry.

SUBSTANCE: invention relates to preparation of compositions for applying heat insulating coating. The composition for applying heat insulating coating contains: a film-forming composition in form of aqueous styrene-acrylic or acrylic dispersion with content of solid substance of 50±1 wt %; glass and/or ceramic and/or sol microspheres with insulated cavities and a hydrophilic water-resistant coating made from a mixture of aminopropyltriethoxy silane and aminoisopropyltriethoxy silane with addition of tetraethoxysilane; filler; cellulose and polymer thickeners; a dispersing agent, an antifoaming agent; a corrosion inhibitor; a coalescence agent; a preservative; water. The method of preparing the composition involves mixing prepared two groups of components.

EFFECT: composition has long period of storage without loss of homogeneity, method of preparing said composition enables maximum preservation of integrity of glass, ceramic and sol microspheres with insulated cavities.
