Embodiment 1

[0041] The processing technology of a double-sided antistatic coating film is shown in the accompanying drawing. The material film stretched 3.0 times by MDO and with a thickness of 75 μm passes through the guide roller 1 and first contacts with the coating roller Ⅰ3 for single-sided coating, and then with the coating Cloth roll II4 is in contact with the other side for coating, and finally preheated and stretched at TDO 105°C for 3.8 times to obtain a double-sided antistatic coating film; coating roll I3 and coating roll II4 are gravure rolls, coating roll I3 and coating The diameter of the roller II4 is 300mm, and the coating roller I3 and the coating roller II4 are respectively located in different coating chambers 2, and the horizontal center distance between the coating roller I3 and the coating roller II4 is 75mm, and the coating roller I3 and the coating roller The rotation direction of the cloth roller II4 is opposite to the feeding direction of the material film. The c...

Embodiment 2

[0044] A processing technology of double-sided antistatic coating film, the material film stretched 3.1 times by MDO and with a thickness of 75 μm is firstly contacted with coating roll I for one-sided coating through the guide roll, and then contacted with coating roll II for the other Coating on one side, and finally preheating and stretching at TDO107°C for 3.85 times to obtain a double-sided antistatic coating film; coating roll I and coating roll II are gravure rolls, and the diameter of coating roll I and coating roll II is 310mm. Coating roller Ⅰ and coating roller Ⅱ are respectively located in different coating chambers, the horizontal center distance between coating roller Ⅰ and coating roller Ⅱ is 62mm, and the rotation direction of coating roller Ⅰ and coating roller Ⅱ is the same as that of the material film The material feeding direction is opposite, the coating liquid in the middle tank enters the coating chamber through the pump and is scraped on the coating roll...

Embodiment 3

[0047] A processing technology for double-sided antistatic coating film. The material film stretched 3.3 times by MDO and with a thickness of 75 μm is firstly contacted with coating roll I for one-sided coating through the guide roll, and then contacted with coating roll II for the other side. Coating on one side, and finally preheating and stretching at TDO110°C for 3.9 times to obtain a double-sided antistatic coating film; coating roll I and coating roll II are gravure rolls, and the diameter of coating roll I and coating roll II is 320mm. Coating roller Ⅰ and coating roller Ⅱ are located in different coating chambers, the horizontal center distance between coating roller Ⅰ and coating roller Ⅱ is 80mm, and the rotation direction of coating roller Ⅰ and coating roller Ⅱ is in line with the material film The material feeding direction is opposite, the coating liquid in the middle tank enters the coating chamber through the pump and is scraped on the coating roller I and coati...

Abstract

The invention relates to a processing technology for a double-faced antistatic coating film. A material film stretched through MDO firstly makes contact with a coating roller I through a guiding roller so that single face coating can be carried out, then, the material film makes contact with a coating roller II so that coating of the other face can be carried out, and finally TDO preheating stretching is carried out; the coating roller I and the coating roller II are gravure rollers, the horizontal center distance between the coating roller I and the coating roller II is 1 / 5-1 / 4 of the diameter of each coating roller, the diameter of each coating roller ranges from 300 mm to 350 mm, the coating roller diameter refers to the diameter of the coating roller I or the diameter of the coating roller II, and the diameter of the coating roller I is equal to the diameter of the coating roller II; and the rotating direction of the coating roller I and the rotating direction of the coating roller II are opposite to the material feeding direction of the material film, and the coating weight of the coating roller I and the coating weight of the coating roller II on the surface of the material film ranges from 3 g / m<2> to 6 g / m<2>. By means of the processing technology, the occurrence of winding bar shaking in the coating process can be effectively avoided, uniform coating of antistatic coating is achieved, and the finally obtained product is uniform in surface coating and has an excellent antistatic effect.

Description

technical field [0001] The invention belongs to the field of polyester film processing and relates to a processing technology of a double-sided antistatic coating film. Background technique [0002] In industrial production and daily life, with the increasing use of insulating materials, static electricity is everywhere, such as dust in industrial production, use of electrical products, static electricity on display screens, etc. The higher the insulation of an object, the easier it is to generate static electricity. Static electricity is very harmful. The existence of static electricity not only affects the quality of industrial products, but also endangers the health of the human body. At the same time, flammable and explosive materials are likely to cause fires and explosions due to static electricity. Therefore, people want to avoid static electricity in these occasions. To avoid static electricity from causing harm to production and human beings. [0003] BOPET polyest...
