Description

technical field [0001] The invention belongs to the technical field of computer cables, and in particular relates to an insulating paint for computer cables and a preparation method thereof. Background technique [0002] Electronic coatings are coating compositions for electronic components or equipment. With the advancement of science and 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, greatly meets the needs of people, and on the other hand drives the refined development trend in many fields. [0003] Insulation performance is a performance that many electronic components or equipment must meet. While protecting electronic components and equipment, electronic coatings must also meet the above performance. Electronic coatings are a new field. Although many coatings have good insulating ...
