From the component selection to the preparation technology, all steps are optimized, and thus the prepared paint coating has the characteristics of good film-forming effect, stable coating performance, and excellent insulation performance, and can well protect the electronic elements or devices.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an electronic insulating 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 sophisticated. This refined development trend, on the one hand, greatly meets people's use needs, and on the other hand, drives the refined development trend in many fields. [0003] Electronic coatings are a refined field developed to meet the needs of the electronics industry. Different from 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 needs to ...
