Description

technical field [0001] The invention relates to a coating, in particular to an activated clay modified fluorocarbon heat-insulating radiation coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's construction industry and the increasingly prominent energy crisis, the energy saving and consumption reduction of buildings is becoming more and more important. my country's building energy consumption accounts for about 27% of the country's total energy consumption, ranking first among all types of energy consumption in the country. [0003] The energy consumption of heating and air conditioning accounts for 55% of the total energy consumption of buildings, and it is still increasing at a rate of 1% per year. Therefore, the research and development of building thermal insulation coatings has significant economic, environmental and social benefits. The use of coatings with heat insulation function on the exterior walls ...

AI Technical Summary

Problems solved by technology

[0004] 1. Poor thermal insulation performance: The density of glass microspheres or ceramic microspheres is higher than that of borosilicate hollow glass microspheres, so at the same dosage, the use of glass microspheres or ceramic microspheres to obtain a dry film insulation cavity is less , the thickness of the coating film is low, and the thermal insulation performance is poor;

[0005] 2. Poor storage stability: glass microspheres or ceramic microspheres have been surface-treated and have low density, which makes the coating prone to viscosity increase and floating during storage;

[0006] 3. Construction is inconvenient: heat insulation coatings using glass microspheres or ceramic microspheres, in order to prevent floating during storage, usually increase the initial viscosity of the coating, so the construction can only be obtained by scraping or batch coating. higher film thickness
