Problems solved by technology

[0003] Now the volume resistivity of antistatic coatings usually reaches 10 5 ~10 10 Ω•m, however, due to the addition of more antistatic fillers, the antistatic coatings prepared in the prior art have poor adhesion, are easy to fall off, are not corrosion resistant, and the preparation process is also complicated, which restricts their use.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to an antistatic coating and a preparation method thereof. Background technique [0002] Anti-static coating is a new type of functional coating that has developed very rapidly in recent years. Anti-static coating is easy to use and can be adapted to various shapes of parts; it can also use the static discharge effect to discharge the static charge accumulated on the surface of the object in time. , to avoid electronic device breakdown, short circuit or short circuit, accidental electric shock and other bad problems caused by static electricity accumulation, so it is widely used in various fields such as electronics, electrical appliances, mechanical equipment, printing, chemical industry and aerospace. [0003] Now the volume resistivity of antistatic coatings usually reaches 10 5 ~10 10 Ω•m, however, due to the addition of more antistatic fillers, the antistatic coating prepared in the pri...
