Abstract

The invention relates to an antistatic coating and discloses an environment-friendly washing-resistant antistatic coating. The antistatic coating comprises the following components by weight percent: 3-9% of film former, 0.1-0.6% of conductive filler, 0.2-3.1% of surfactants, 0.1-0.6% of coupling agents, 0-0.1% of acid, 5-20% of ketone solvent, 5-20% of alcohol solvent and 47-86.5% of water. 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; with water as a main solvent, the prepared antistatic coating is non-toxic and environment-friendly; 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, relates to an environment-friendly washing-resistant antistatic coating and a preparation method thereof. Background technique [0002] Electrostatic charge exists widely in our daily life, which may cause the following four hazards: (1) electrostatic discharge; (2) electrostatic adsorption; (3) the existence of electrostatic charge will increase the reactivity of substances; (4) static electricity can Harmful to human health. One of the most serious hazards is that electrostatic discharge can generate sparks, which may cause explosions and fires where flammable and explosive materials exist. Secondly, the current of fast electrostatic discharge can cause breakdown and other damage to modern electronic products, especially integrated circuits. . [0003] Polymer materials are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fi...
