Abstract

The invention provides a conductive coating for communication equipment and a preparation method of the conductive coating. The coating comprises components in parts by mass as follows: 5-15 parts of graphite, 0.5-3 parts of potassium stannate, 0.3-0.7 part of aluminum hydroxide, 2-5 parts of titanium dioxide, 0.6-1.5 parts of quartz sand, 13-20 parts of polyester resin, 0.5-1.5 parts of polyvinylpyrrolidone, 18-26 parts of an ethyl cellosolve, 0.05-0.15 part of benzoin and 0.02-0.04 part of titanate. The coating is excellent in conductivity, good in shock resistance and water resistance, short in drying time and capable of removing accumulated electrostatic charges.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a conductive coating for communication equipment and a preparation method thereof. Background technique [0002] In today's society where information is developing rapidly, communication equipment is an indispensable daily necessities for people. Communication equipment includes mobile phones, computers, network cards, radios and so on.
