High-temperature nano-composite coating and preparation method thereof, and small bag flexible packaging coating

Abstract

The present disclosure provides a high-temperature nano-composite coating and a preparation method thereof, and a small bag flexible packaging coating. The high-temperature nano-composite coating provided by the present disclosure controls the fiber length. Moreover, high-temperature reinforcing filler and high-temperature expansion filler are introduced, to make the coating have ultra-high strength at high temperature without cracks caused by shrinkage at high-temperature. In addition, nanopowder, high-temperature skeleton filler and other additives are introduced to make the coating be uniform and stable and reach a slurry state similar to toothpaste. There is no precipitation and stratification during the placement process. Small packaging can be realized to facilitate construction and operation. Besides, the coating has a good bonding to furnace lining, and will not fall off from the furnace lining, thereby prolonging the service life of the furnace lining.
