High-temperature-resistant heat-insulating coating for kiln as well as preparation method and application thereof
The invention provides a high-temperature-resistant heat-insulating coating for a kiln as well as a preparation method and application thereof. The thermal insulation coating comprises a primer and a topcoat, and in parts by mass, a component A of the primer is mainly composed of 2.0 modulus sodium silicate, and a component B of the primer is mainly composed of metakaolin, mineral powder, 200-mesh quartz sand, 80-120-mesh quartz sand and 40-80-mesh quartz sand; a component A of the surface coating agent is mainly composed of 2.0 modulus sodium silicate, and a component B of the surface coating agent is mainly composed of metakaolin, mineral powder, expanded vermiculite, expanded perlite, a diatomite and zeolite mixed modified material, an air entraining agent and basalt fibers. Sodium silicate, metakaolin and mineral powder serve as film forming substances and have high binding force with metal, meanwhile, raw materials in the formula of the primer and the formula of the surface coating are matched with each other, and the primer and the surface coating are matched with each other and have a synergistic effect, so that when the heat insulation coating is applied to metal shells of kilns and the like, the heat insulation effect is good. The coating has the characteristics of high bonding strength, good heat insulation performance, good freeze-thaw resistance and the like.
本发明提供了一种窑炉用耐高温隔热涂料及其制备方法和应用。所述隔热涂料包括底涂剂和面涂剂，按质量份计，所述底涂剂的A组分主要由2.0模数硅酸钠组成，B组分主要由偏高岭土、矿粉、200目石英砂、80～120目石英砂、40～80目石英砂组成；所述面涂剂的A组分主要由2.0模数硅酸钠组成，B组分主要由偏高岭土、矿粉、膨胀蛭石、膨胀珍珠岩、硅藻土沸石混合改性料、引气剂、玄武岩纤维组成。其中，硅酸钠、偏高岭土和矿粉作为成膜物质，与金属具有较强的结合力，同时底涂剂和面涂剂各配方中的各原料相互配合，并且底涂剂和面涂剂相互配合，协同作用，使得上述隔热涂料应用于窑炉等金属外壳上时，具有结合强度高、隔热性能好、耐冻融性能好等特点。
