Abstract

The invention discloses a preparation process for a high-temperature-resistant high-thermal-conductivity insulating paint, belonging to the technical field of paints. The paint comprises the following raw materials by mass: 12 to 23% of epoxy modified organosilicone resin, 33 to 48% of a solvent, 0.7 to 0.9% of a silane coupling agent, 36 to 42% of a filling material, 0.1 to 0.3% of a curing agent, 0.03 to 0.08% of ceramic powder and 0.02 to 0.07% of nanometer diamond. The paint prepared in the invention can be used for a long time at a high temperature and has good stability, insulating properties, wear resistance and good corrosion resistance; and the preparation process is simple and has good operability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant and high-thermal-conduction insulating coating and a preparation process of a high-temperature-resistant and high-thermal-conduction insulating coating. Background technique [0002] Coating is a kind of coating on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. "Coatings have protective functions, decorative functions and other basic functions. With the development of the times, the requirements for coatings are getting higher and higher. With the increasing emphasis on environmental issues and energy issues around the world, traditional coatings have been unable to meet Realistic demand, environment-friendly coatings and multi-functional energy-saving coatings...
