Problems solved by technology

As we all know, if the epoxy silicone resin is directly heated and cured, its hardness is difficult to reach more than 4H. If it is cured with a curing agent, although the hardness can meet the requirements, it will appear yellowing after 24 hours of use at 250 ° C.
Therefore, the paint film provided by this patent will inevitably have yellowing and aging after high temperature curing, and the corresponding application performance cannot be guaranteed
[0004] At the same time, the high-temperature protective coating material currently used in my country's carrier-based aircraft engine control system is conventional epoxy-modified silicone coating, which has low hardness. During storage, transportation and installation: the surface is easy to be scratched and bumped. The maintenance work has seriously limited the combat effectiveness of our country's weapons and equipment

Abstract

The invention relates to a high-performance ceramic-based epoxy modified organic silicon coating material, which is characterized in that a boehmite modified epoxy resin, an epoxy modified organic silicon resin and a curing agent are selected as main components, and a ceramic-based resin is gradually formed in a resin curing and cross-linking process, so that high hardness and wear resistance of the epoxy modified organic silicon coating material are realized, and the coating material has excellent oil resistance and high-temperature resistance. According to the invention, the ceramic-based epoxy modified organic silicon coating material has the advantages of simple construction, no need of complex equipment, good film-forming property of the prepared material, and high adhesive force; and by applying the ceramic-based epoxy modified organic silicon coating material, the scratch-resistant protection and corrosion protection effects on equipment can be realized, and the coating can also be widely applied to high-temperature protection of facilities such as chimneys, hot pipelines and the like, and has relatively high economic benefits.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant coating materials, in particular to a high-performance ceramic-based epoxy-modified organic silicon coating and a preparation and application method thereof. Background technique [0002] At present, there are two types of high-temperature-resistant coatings commonly used in the prior art: one is ceramic coatings, and the other is silicone coatings. Ceramic coatings can be applied to environments above 1000°C by utilizing the high temperature resistance of their inorganic materials, but their construction is difficult, they are not suitable for large components, and their maintenance performance is poor. Therefore, their scope of application is narrow. Silicone coatings are mostly used in environments below 1000°C, and are often used in high-temperature chimneys due to their excellent construction convenience and high temperature resistance. Usually the chimney is located in th...
