Preparation and Properties of Infrared Radiation Energy-saving Coating with High Thermal Shock Resistance
摘要
Abstract
Infrared radiation paint was prepared from cordierite, SiC, Cr2O3, TiO2, SiO2 as the initial raw material by mechanical mixing with phosphate adhesive. And then an energy-saving infrared radiation coating was prepared on high aluminum brick surface by brushing process. Thermal stability of the infrared radiation powders were investigated by Thermo Gravimetric-Differential Scanning Calorimeter (TG-DSC). The flowability of the prepared paint and the adhesion between infrared radiation coating and substrate were characterized by paint-4 cup and paint film adhesion tester. The thermal shock resistance of the obtained coating was investigated by water cooling and air cooling. The effect of SiC content on the emissivity of the coating was discussed. The research results show that:the paint is well-distributed and the flowability is quite good at the ratio 2:1 of adhesive to infrared radiation powders. The adhesion strength between coating and substrate increased after high temperature heat treatment at 1100℃. The thermal shock resistance of the coating was excellent. The emissivity of the infrared radiation coating containing 40%SiC is the highest, which can reach 0.91. Besides, the inner temperature of the baking furnace was increased by 128℃ after the energy-saving infrared radiation coating being used, and the energy consumption decreased 8%.关键词
