Problems solved by technology

Metal filler conductive coatings are expensive, have low connection strength, and particle migration will occur under DC electric field and moisture conditions, which will reduce the conductivity and affect its service life
Carbon-based fillers are cheaper than metal fillers, but due to their darker color, they are limited in applications that require bright colors
In addition, the conductive coatings in the prior art generally have technical problems such as poor wear resistance, poor chemical resistance, weak adhesion, thin construction film and slow drying speed.
[0004] Chinese invention patent CN200510028828.9 discloses a preparation method of a new type of conductive coating, which uses mixed valence molybdenum oxide and mixed valence tin oxide as conductive agents to reduce the resistivity of the material, and the resistivity is at 10 -1 -10 2 Ω·cm, but the conductive coating is expensive and the raw materials are not easy to obtain

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a conductive paint and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of electronic technology, electronic circuits and electronic components have reached the level of high integration, functionalization, digitization and high frequency, and are applied in various fields of industry and family life. The generation and transmission of electronic information , reception and processing must use electromagnetic waves as the carrier. On the one hand, electromagnetic waves bring a lot of convenience to people's lives and play an important role in information dissemination. On the other hand, they will cause negative effects such as electromagnetic interference and electromagnetic radiation. It poses a serious threat to human health and the natural environment. In addition, electronic components are prone to static elec...
