Research and application of special cooling coating suitable for ground equipment
[Introduction]To effectively reduce the temperature rise of missile caused by solar radiation,the cooling performance of a special coating for ground equipment was studied.[Method]By analyzing the binders,pigments,and fillers,the combination of epoxy resin and curing agent was determined to be the binder for the special cooling coating,and rutile titania would be the main pigments and fillers for it.The design principle of the special cooling coating was determined through the composition of epoxy and curing agent as carried out.A heat conduction model for the coating was established,the numerical simulation of ground equipment was carried out,and the sources of radiation were analyzed.[Result]The environmental adaptability and cooling performance of the special coating were verified experimentally with simulated samples.[Conclusion]The special cooling coating solves the problem of high internal temperature rise of ground equipment under solar radiation,laying a foundation for the application of ground equipment.
