Problems solved by technology

[0008] The electrical conductivity of electronic coatings is mainly aimed at electronic components that require electrical conductivity, such as electrodes. If exposed electrodes are used for a long time, they will inevitably be eroded from the outside world. This requires coatings to protect the electrodes, but if the coatings are not Conductive properties, then the proper functioning of the electrode cannot be guaranteed, therefore, in this case, the conductivity of the coating is very important

Description

Technical field [0001] The invention belongs to the technical field of coatings, and particularly relates to an electronic conductive coating and a preparation method thereof. Background technique [0002] Electronic coatings are coating compositions for electronic components or equipment. With the advancement of technology, the types and quantities of electronic components and equipment are increasing, and the volume is getting smaller and smaller, and the design is getting more and more refined. This refined development trend, on the one hand, has greatly met people's needs for use, and on the other hand, it has driven the refined development trend in many fields. [0003] Electronic coatings are a refined field developed to meet the needs of the electronics industry. Unlike general coatings, coatings in the electronic field have stricter performance requirements for coating compositions. [0004] First of all, electronic coatings are generally sprayed, so the preparation process...
