Abstract

The utility model discloses an anti-static membrane, which comprises a membrane body. The membrane body is coated with electricity conductivity metal powder. Metal powder forms a chain. The electricity conductivity surface is metal powder medium. The static release time is much shorter than traditional anti-static materials. The function is stable and cost low.

Description

A kind of electrostatic prevention film

Technical field

The utility model relates to a kind of packing, especially for the electrostatic prevention film of electronic devices and components and plastic product packaging bag.

Background technology

Electronic component and plastic product all can produce static because of mutual friction mutually in transit, these static can produce fatal harm to electronic component, plastic product then is easy to generate spark and then causes fire, generation for fear of this situation, existing antistatic packaging bag is all made by the plastics of electrostatic prevention, or at the outer spraying of normal packet pack conductive material.Antistatic plastic electrostatic leakage overlong time, the packing that are coated with conductive material outward are easy to generate coating and pollute, and anti-static effect is bad, and function is less stable also, more than two kinds of packing also cause cost higher because of the worker is complicated.

Summary of the invention

In order to overcome the deficiencies in the prior art, main purpose of the present utility model provides a kind of electrostatic leakage time weak point, electrostatic-proof function is stable and the low electrostatic prevention film of cost.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of electrostatic prevention film, comprise membrane body, and be coated with conductive metal powder on the membrane body, metal powder is coupled to each other into chain.

The beneficial effects of the utility model are: the electrostatic prevention film conducting surface is the metal powder medium, and it is many that electrostatic leakage time antistatic material as compared with the past will be lacked, and also quite stable of function, and spraying conductive metal powder cost is also very low on membrane body simultaneously.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

With reference to Fig. 1, a kind of electrostatic prevention film comprises membrane body 1, is coated with conductive metal powder 2 on the membrane body 1, and metal powder 2 is coupled to each other into chain.Metal powder can be made up of aluminum particulate, iron particle or other metal particles, connecting catenulate metal powder conductivity water temperature and depth improves greatly, when making the packaging bag use, the static that produces on vent discharge sub-element or the plastic product rapidly, the while function is quite stable also, this electrostatic prevention film is that metal particle is painted on plastics or other packing, and technology is simple, and cost also reduces greatly.

Above-mentioned just the utility model preferred embodiment but should not constitute restriction of the present utility model, so long as adopt the technical scheme that is equal to the utility model also should be within the protection domain of the invention.

Claims

1. an electrostatic prevention film comprises membrane body (1), it is characterized in that: be coated with conductive metal powder (2) on the membrane body (1), described metal powder (2) is coupled to each other into chain.
