Abstract

The invention relates to an antistatic coating and discloses a washing-resistant antistatic coating. The antistatic coating comprises the following components by weight percent: 15-25% of film former, 2-5% of conductive fillers, 0.5-1% of dispersing agents, 0.5-1% of coupling agents, 0.2-0.5% of defoaming agents, 0.3-0.6% of levelling agents, 0.5-1% of anti-settling agents and the balance of solvents. The preparation method can be implemented to prepare the antistatic coating which is efficient, has low toxicity and strong adhesion, is resistant to washing with water and organic solvents and is convenient to use, prepare and process; the components of the antistatic coating are the raw materials which are easily available, so the cost of the prepared antistatic coating can be effectively lowered; and the preparation method is carried out under normal temperature and pressure, the conditions required by the preparation process are easy to reach, the preparation flow is simple and the operability is strong.

Description

technical field [0001] The present invention relates to an antistatic coating, more specifically, to a washing-resistant antistatic coating and a preparation method thereof. Background technique [0002] Static electricity is an objective natural phenomenon that can be generated by various methods such as contact or friction. It is characterized by high voltage, low power, small current and short action time. Static electricity is a static charged charge, whether it is a conductor or an insulator, it is charged under the action of static electricity. Static electricity is ubiquitous in our daily life. The static electricity when people walk through chemical fiber carpets is about 35,000 volts, and the static electricity when reading plastic manuals is about 7,000 volts. Although you may not experience these static electricity at ordinary times, for some sensitive instruments, these static electricity voltages may cause great harm. [0003] Polymer materials are materials ...
