Determination device and method for anti-condensation property of coating

The invention discloses a determination device and method for anti-condensation property of coating. The device for determining anti-condensation property of coating comprises a low temperature medium circulation tank and a constant temperature and humidity room. The low temperature medium circulation tank is provided with a low temperature medium control instrument for control of temperature of the low temperature medium in the circulation tank; and the constant temperature and humidity room is provided with a moisture condensation device, a fixed bracket, a moisture condensation collecting container and a temperature and humidity control instrument, the temperature and humidity control instrument is used for controlling the temperature and humidity of air in the constant temperature and humidity room, the moisture condensation device is used for containing the low temperature medium, and the outside of the moisture condensation device is for coating a coating to be tested, and the moisture condensation collecting container is for collecting moisture condensation formed on the surface of the moisture condensation device. The invention creatively provides the device and the method for determining the anti-condensation property of the coating, and determines the anti-condensation property rating criteria; and the invention can effectively simulate the temperature and humidity environment of inner and outer walls, and can fast, conveniently and accurately determine the anti-condensation property of the coating.
