Curing Time and Mechanism of Thermal Insulating Coating Under Different Conditions

In order to confirm the curing status of thermal insulating coating under the different environmental factors, a series of raw materials were selected to prepare thermal insulating coating with radiation reflective property. The curing time and surface status of thermal insulating coating were studied by using the equipment releasing solar radiation. The influence of humility on the curing time was studied through using facility of constant temperature and humility. The law of wind speed effect on curing time was analyzed by tester of wind controlling. The microstructures of thermal insulating coating under different factors were represented and the curing mechanisms under different environmental factors analyzed, which lay a solid base for the good application of thermal insulating coating in road pavement.
