Problems solved by technology

[0003] In the prior art, high-temperature-resistant coatings are commonly used in mold casting of environmental protection equipment. After manual brushing, this coating has low affinity with the surface of the protected object, large gaps between molecules, and low strength. It will fall off after repeated heating and cooling. At the same time, the surface of the coating is still rough and there are a lot of attachments. It is easy to damage the protective layer when cleaning the attachments.
