Problems solved by technology
However, when encountering high-frequency interference signals, the inductance of the magnetic ring will be short-circuited, and the anti-static effect cannot be exerted. Moreover, its volume is relatively large, so it is not suitable for installation in the car body

Embodiment 1-3
[0053] According to the materials and proportions provided in Table 1, an appropriate amount of binder is added and mixed uniformly to prepare a coating, and then the coating is coated on a metal plate to prepare an antistatic plate 1-3. Fix the above-mentioned antistatic plate 1-3 on the battery and test its voltage stability. The basic situation of the electromagnetic interference board 1-3 is as follows:

The invention provides an antistatic plate, an antistatic device and application of the antistatic device. The antistatic plate and the antistatic device can be arranged at any position of electric equipment, are used for eliminating static electricity of the electric equipment, have stable performance and do not influence human health. The antistatic plate comprises a metal plate (2) and a coating (3) which is formed on any surface of the metal plate (2); a grounded lead (4) is connected to the metal plate (2); and the coating (3) comprises a powdery piezoelectric material, a dielectric and a silicone coating which are used as main components. The antistatic device is formed by overlapping multiple layers of the antistatic plates, and preferably is provided with one or more sandwich structures which are formed by clamping overlapped bodies of the multiple layers of the antistatic plates by using an aluminum mesh.
Description
Technical field [0001] The present invention relates to the field of antistatic, in particular to antistatic plates, devices and applications thereof used in electrical and electronic equipment. Background technique [0002] Any object is charged internally. Under normal conditions, the number of positive and negative charges are equal, and there is no external charging phenomenon. However, when two different objects are in contact or rubbed, one object has negatively charged electrons. It will cross the interface and enter another object, and static electricity will be generated. And because their charge accumulates, they generate a very high static voltage. When two objects with different charges are separated or touched, an electric spark occurs, which is the phenomenon of static discharge. With the large number of applications of electrical appliances and electronic equipment, static electricity is everywhere and all the time. They are potential sources of interference for e...
