Embodiment 3
[0076] Embodiment 3 coating performance test
[0077] The China Academy of Building Research and the China Academy of Space Technology jointly tested Embodiment 1, and the results are shown in Table 3. All performances of Embodiment 1 are better than national technical indicators.
[0078] table 3
[0079]
[0080]
[0081] The coating prepared in the pilot test of the formula of Example 1 is used in the X-ray perspective room of Xinglongtai District Center for Disease Control and Prevention, Panjin City. The building is 15.24 meters long, 4.64 meters wide and 3.2 meters high. The roof is made of dark blue curved color steel plate, and the facade is made of light gray old latex paint. The total painting area of the top and facade is about 260㎡. Roller coating is used for construction. Firstly, one coat of sealing primer is applied. After drying (about 20 minutes), the pilot product of the formula in Example 1 is used for roller coating once, and the second coat of r...
