HIGH-TEMPERATURE NANOCOMPOSITE COATING AND METHOD OF ITS PREPARATION, AS WELL AS COATING FOR FLEXIBLE PACKAGING IN THE FORM OF A SMALL BAG Russian patent published in 2023 - IPC C09D1/00 C09D5/18 C09D7/40 C09D7/61 C09D7/63 C08K3/13 B82Y30/00 

FIELD: nanocomposite coatings.

SUBSTANCE: invention relates to the field of coatings for a high-temperature furnace, and specifically relates to a high-temperature nanocomposite coating and to a method for its preparation, as well as to a coating for flexible packaging in the form of a bag. High temperature nanocomposite coating, contains water and the following components in wt.%: high temperature resistant inorganic fibre 10% ~ 50%; reinforcing filler 10% ~ 20%; high temperature expanding filler 5% ~ 15%; frame filler 7% ~ 30%; nanopowder 3%~10%; inorganic suspending agent 0%~20%; inorganic binder 10% ~ 50%; organic additive 3% ~ 15%; with water accounting for 10% ~ 50% of the total mass of all the above components. The invention also relates to a method for preparing a high-temperature nanocomposite coating and a coating for flexible packaging in the form of a bag.

EFFECT: creation of a high-temperature nanocomposite coating with ultra-high strength and compactness at high temperature, with little shrinkage, no cracks formed at high temperature, that can withstand ultra-strong air flow erosion and erosion under the influence of the atmosphere of a cracking furnace in the petrochemical industry.
