Embodiment 1

[0055] see Figure 1-10 , a kind of antistatic type PET film coating process with wear-resistant structure, comprises the steps:

[0056] S1. Pre-preparation: clean and dry the PET film base layer 10 in advance, and add matching coating materials into the antistatic layer coater 1 and wear-resistant layer coater 3;

[0057] S2. Electrostatic coating: the PET film base layer 10 is first guided into the antistatic layer coating machine 1 by a conveying device, and one layer of antistatic coating 11 is coated on the surface of the PET film base layer 10;

[0058] S3. Electrostatic drying: After the antistatic layer coating machine 1 is coated, the conveying device transports the PET film base layer 10 coated with the antistatic coating 11 to the No. 1 dryer 2, and the antistatic coating 11 is dried and stabilized ;

[0059] S4. Wear-resistant coating: the dried PET film base layer 10 with antistatic coating 11 is transported to the wear-resistant layer coating machine 3, and a ...

Embodiment 2

[0069] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 2 , the antistatic test assembly 5 includes a static emission cylinder 501, the antistatic film body 20 is provided with a static emission cylinder 501 near the side of the PET film base layer 10, and the side of the antistatic film body 20 away from the PET film base layer 10 is provided with a breakdown induction cylinder 503, the side of the static emission tube 501 close to the antistatic film body 20 is fixedly connected with a plurality of voltage scattering heads 502, and the side of the breakdown induction tube 503 close to the antistatic film body 20 is provided with a voltage induction tube that matches the breakdown induction tube 503....

Embodiment 3

[0074] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to Figure 6 and Figure 7 The magnetic wear-resistant protective layer 12 includes a plurality of elastic struts 1201 distributed in an array, the lower ends of the plurality of elastic struts 1201 are fixedly connected with the antistatic coating 11 , and the upper ends of the elastic struts 1201 are fixedly connected with the elastic struts 1201 . When the magnetic connection ball 1202 is in contact with the outside to generate friction, the magnetic connection ball 1202 changes the surface-line contact to the surface-point contact, effectively reducing the generation of friction, and through the action of the elastic support 1201, effectively reducing ...

Abstract

The invention discloses a coating process of an antistatic PET film with a wear-resistant structure, and belongs to the field of PET film packaging. The coating process of the antistatic PET film with the wear-resistant structure comprises the following steps that preparation is conducted; electrostatic coating is performed; electrostatic drying is performed; wear-resistant coating is performed; wear-resistant drying is performed; according to an electrostatic breakdown test, wear-resistant degree of an antistatic coating can be effectively improved through a magnetic type wear-resistant protective layer, the loss of the antistatic coating in storage and transportation is reduced, antistatic effect of the antistatic film body is effectively ensured, and use performance of the antistatic film body is improved; antistatic effect of the antistatic film body is judged through an antistatic test assembly, so that production quality of the antistatic film body can be effectively guaranteed, raw material waste caused by early-stage parameter adjustment is reduced, debugging efficiency and debugging precision are improved, antistatic film bodies with different specifications are produced according to different antistatic requirements, so that production applicability is improved.

Description

technical field [0001] The invention relates to the field of PET film packaging, in particular to an antistatic PET film coating process with a wear-resistant structure. Background technique [0002] Today's world has entered the information age, and electromagnetic waves of various frequencies and wavelengths fill the entire space of the earth. These electromagnetic waves will cause varying degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., resulting in data distortion, Communication disorder. The static electricity generated by electromagnetic induction and friction will be destructive to various sensitive components, instruments, certain chemical products, etc., if the high-voltage discharge is generated due to the accumulation of static electricity in the packaging film, the antistatic PET packaging film is also very important. [0003] The feature of antistatic PET packaging film is that by coating a la...
