Solution Approach 1:

The patent applies composite materials by combining inorganic components (metal oxides such as zinc oxide, aluminum oxide, silicon oxide, and clay minerals) with organic components (polymer resins) to create a hybrid surface treatment film. This composite structure enables the film to maintain both the protective properties of organic materials and the heat resistance of inorganic materials, resolving the contradiction between general protection performance and high-temperature stability.
