HEAT-INSULATING POLYMERIC MATERIAL AND METHOD FOR ITS PREPARING Russian patent published in 2006 - IPC C04B26/12 C04B38/10 C08L61/32 C08J9/12 

FIELD: inorganic chemistry, chemistry of polymers.

SUBSTANCE: invention proposes heat-insulating polymeric material comprising the following components, wt.-%: carbamidoformaldehyde resin, 43.8-61.9; alkylbenzene sulfoacid of sort A as a surface-active substance, 0.25-0.5; ortho-phosphoric acid, 1.05-3.3 as an acid hardening agent; a modifying agent, 0.015-0.17, and water, 35.6-53.2. As a modifying agent the material comprises polyacrylamide-gel "Ammiachnyi" or polyacrylamide, or hexamethylene diaminoadipinate, or caprolactam, or ammonium polyphosphate. Also, invention describes a method for preparing the heat-insulating material. Invention provides enhancing exploitation indices of foam plastic due to improving regularity of the material structure providing the low emission of formaldehyde in the process of its producing and exploitation of foam plastic and improving its physical-chemical indices and expanding filed of its using also. Invention can be used in making foam plastic-base materials for insulation of constructions in housing, agricultural and industrial building.

EFFECT: improved preparing method, improved and valuable properties of material.
