The paint can be applied to a lot of devices requiring high power heat dissipation, and can provide different optimized ratios according to different power heat dissipation needs.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a heat dissipation and high temperature resistant nano anticorrosion coating and a preparation method thereof. Background technique [0002] Metals are used in every corner of our lives, from daily necessities, industrial supplies to aviation, aerospace and other fields, so that the use of metals plays a vital role in daily life and the progress of the times. However, the corrosion of metals has brought a series of problems such as social and economic waste and environmental pollution, and has had a profound impact on people's daily life and production and manufacturing. [0003] Metal corrosion refers to the damage or deterioration of metals caused by the environment. Therefore, the anti-corrosion treatment of metal surfaces becomes very important. The traditional anti-corrosion treatment includes the long-established hexavalent chromium conversion coating technology, the most ...
