AI Technical Summary
Existing inorganic high-temperature thermal insulation coatings suffer from poor interfacial compatibility and insufficient interfacial bonding between the thermal insulation filler and the inorganic film-forming matrix, resulting in limited thermal insulation efficiency and failing to meet the high-performance thermal insulation protection requirements under harsh high-temperature environments.
Boron-aluminum dual-doped lithium silicate inorganic resin is used as the film-forming matrix, combined with amorphous Al2O3-SiO2 nano-coated mullite hollow ceramic microspheres and modified nanoporous zirconium dioxide and titanium dioxide to form a multi-level thermal insulation system. The interfacial bonding strength and thermal insulation performance are improved through covalent bonding and modification treatment.
It achieves improved high-temperature service stability and interface bonding strength, forming an all-round heat insulation mechanism, and is suitable for coating application needs in various high-temperature heat insulation scenarios.
