SYSTEM AND METHOD OF PRODUCING IN SITU- FOAM MATERIAL USED IN PLACE Russian patent published in 2018 - IPC C08J9/30 C08J9/00 C08J9/12 C04B38/00 

FIELD: chemistry.

SUBSTANCE: system consists of the following components: 50 to 98 wt % of one or more inorganic fillers A), 2 to 10 wt % of one or more water-soluble cationic polymers B), 0.5 to 48 wt % of one or more surfactants C), 0.01 to 1 wt % of one or more cross-linking agents D) reactive with respect to polymers B, 0 to 10 wt % of one or more additives E). The amounts of components A) -E) in weight percent are indicated in terms of anhydrous components, and the total amount of components A) -E) is 100 wt %. The method for producing in-situ foam materials includes the use of system components and foaming by means of gas or a gas mixture. In-situ foam material is used for thermal insulation, for filling cavities and hollow products and as a fire shutter or part of a fire shutter.

EFFECT: producing the foam material with little propensity for shrinkage, low emission of harmful substances, suitability for cutting resulting from a short time later after foaming, a low calorific value, small smoke and lack of dripping melt when burned.
