[0002] Fire retardant coatings are specialized coatings applied to combustible substrates to reduce their flammability, slow the spread of fire, and ultimately improve their fire resistance. Therefore, fire retardant coatings undergo numerous rigorous flame retardancy tests during their development and production processes.

[0003] Chinese patent CN 214252171 U discloses a fire retardant coating test device. The utility model discloses a fire retardant coating test device, including a housing, a test bracket, and a controller. The housing is provided with a cavity for accommodating a coating plate, and the test bracket is fixedly arranged in the cavity. The test bracket includes a support frame for supporting the coating plate and a tray for storing fuel, and the tray is fixedly connected to the support frame via a horizontal bracket. The top of the housing is provided with an air vent that communicates with the cavity, and the upper end of the air vent is provided with a ventilation hood. By providing the housing and the test bracket, the coating plate can be placed on the support frame and maintained at an inclined angle with the tray, so that the coating plate is fully in contact with the flame, thereby ensuring the accuracy of the coating fire resistance performance test. Through the ventilation hood and the air intake fan, it is ensured that the fuel can be fully burned and the smoke generated by the combustion can be quickly discharged outside the housing, making it convenient for the tester to monitor the test situation in the housing in real time, thereby improving the safety of the fire retardant coating test device.

[0004] The background technology of the above patent points out that the existing device is not conducive to the diffusion of smoke, causing the paint plate to explode, and it is difficult to test the fire resistance of the paint, which restricts the research and development of fire-retardant paint.
