Performance test

heat insulation temperature difference: preparing two steel plates A and B with the sizes of 200mm x 300mm x 2mm, wherein the steel plate A is uniformly sprayed with a layer of the heat-insulating coating in the embodiment 1, the steel plate B is not sprayed, then the steel plate A is placed above the steel plate B, an infrared lamp with the power of 500W and the heating length of 165mm is adopted to irradiate the steel plate A for 60min, and finally, the temperature of the steel plate A and the temperature of the steel plate B are measured by an infrared thermal imager, so that the heat-insulating effect of the heat-insulating coating in the embodiment 1 can be measured; the method for testing the heat insulation effect of the heat insulation coating prepared in other embodiments is the same as that in embodiment 1, wherein the spraying thickness of the heat insulation coating is kept consistent, and the positions of the measured temperatures are kept consistent when the temperatures of the steel plate A and the steel plate B are measured by a thermal infrared imager.
Accelerated aging resistance: the accelerated aging resistance of the thermal insulation coatings prepared in examples 1-10 was tested according to the national standard GB/T1865-2009 xenon arc radiation for artificial weathering of paints and varnishes and for exposure and filtration of artificial radiation.
TABLE 2
It can be seen from the combination of examples 1 to 4 and table 2 that the insulation temperature difference of the insulation coating obtained by the method of examples 2 to 4 is significantly increased compared to that of example 1, which illustrates that the insulation wallboard prepared by the insulation coating of examples 2 to 4 can improve the insulation performance of the insulation wallboard, thereby reducing the energy consumption inside the building.
By combining the embodiment 3 with the embodiments 5 to 6 and combining the table 2, it can be seen that the thermal insulation material prepared in the embodiment 3 is modified by using the steel fibers in the embodiments 5 to 6, and then the thermal insulation material in the embodiment 3 is replaced by the modified thermal insulation material, so that the thermal insulation coating with better accelerated aging resistance is obtained, and the possibility that the thermal insulation coating falls off from the wallboard body is reduced; in addition, example 5 is different from example 6 in that the ball milling speed of the ball milling modification of the steel fiber and the thermal insulation material is not the same, wherein the modified thermal insulation material obtained when the ball milling speed is 500rad/min is better than the modified thermal insulation material obtained when the ball milling speed is 200 rad/min.

By combining the example 6 with the examples 8-10 and combining the table 2, it can be seen that when the magnesium silicate in the example 6 is directly replaced by the waste glass powder in the example 8, and the magnesium silicate in the example 6 is replaced by the waste glass powder pretreated by the waste glass powder in the example 9 only by adopting a high-temperature mode, the heat insulation temperature difference of the heat insulation coating obtained by the two modes is obviously reduced, and the accelerated aging resistance of the heat insulation coating is also reduced; when the modified waste glass powder obtained by treating the waste glass powder by the method in example 10 is used instead of the magnesium silicate in example 6, the heat insulation performance and the accelerated aging resistance of the obtained heat-insulating coating are not much different from those of example 6. Therefore, the waste glass powder can be used as the inorganic silicon raw material to improve the utilization efficiency of resources.
