Preparation method of high-strength low-heat-conduction heat-preservation castable
The invention relates to the technical field of castable materials, and particularly discloses a preparation method of a high-strength low-heat-conduction heat-preservation castable material which is composed of light expanded perlite and auxiliary materials. The auxiliary materials comprise 55%-60% of an aerogel precursor, 3%-5% of a surfactant, 10%-13% of nanoparticles, 12%-18% of an aluminum oxide coating, 5%-8% of polyphenyl particles and 2%-4% of titanium dioxide; by utilizing the characteristics of aerogel, the castable with lower density can be prepared, so that the load of the whole structure is reduced, the aerogel has excellent heat insulation performance, the heat stability of the castable is further improved by the nano coating, a lower heat conductivity coefficient can be realized under the combined action, and the heat insulation performance is improved; through sintering and optimized aerogel preparation conditions, the compressive strength and structural stability of the castable can be improved, the high-strength low-heat-conduction heat-preservation castable with good performance can be prepared within a relatively short time by utilizing aerogel and a nano coating technology, and the production efficiency is improved.
