Problems solved by technology

However, the plastic film is usually made of PU material, which cannot prevent the generation of static electricity well. There will still be a lot of static electricity generated by wrapping the wires and cables on the drag chain with plastic film.
If you use a film without anti-static treatment, the surface static electricity of the film is very large during use, and a lot of dust will accumulate on the surface of the film with a large amount of static electricity. Static electricity and dust will directly affect the product for products that require a harsh production environment. quality or there are hidden dangers in product quality. In addition, high static electricity can also cause great damage to electronic products, which can directly burn or break down electronic components
Films without anti-static treatment cannot meet the production requirements of automated assembly lines with harsh production environments

Abstract

The invention discloses membrane antistatic fluid. The membrane antistatic fluid is prepared from, by weight, 60-80% of ethyl alcohol, 1.6-10% of conductive liquid, 2.8-14% of n-hexane, 0.1-0.2% of essence and 7-30% of water. The invention further discloses a preparation method of the membrane antistatic fluid. The method includes the steps that firstly, ethyl alcohol, conductive liquid, n-hexane, essence and water are evenly mixed according to the ratio; secondly, the surface of a varicosity polytetrafluoroethylene membrane is evenly coated with the antistatic fluid; thirdly, the varicosity polytetrafluoroethylene membrane evenly absorbs the antistatic fluid; fourthly, the polytetrafluoroethylene membrane with the antistatic fluid absorbed is dried; fifthly, the dried polytetrafluoroethylene membrane is rolled. The antistatic membrane manufactured through the formula and the method is used for wrapping a towing chain, can effectively reduce the amount of static electricity generated by the towing chain in work, and meanwhile effectively achieves the dustproof effect.

Description

[0001] 【Technical field】 [0002] The invention relates to a film antistatic liquid, in particular to a thin film antistatic liquid and a method for preparing the antistatic film. [0003] 【Background technique】 [0004] In the automatic assembly line production process, manipulators are often used, and drag chain structures are used in many places in the manipulator. The drag chains, manipulators and tow chains connected to the manipulators in the mechanism equipment are constantly working, and the tow chains of the manipulators are connected. The wires and cables are constantly moving back and forth with the tow chain, and the long-term movement of the wires and cables will cause the rubber of the wires and cables to break and may even break them. Since the tow chain, manipulator and the tow chain connected to the manipulator will also generate a lot of dust and static electricity during long-term operations, and for precision electronics, dust and static electricity are the ...
