Problems solved by technology

Since the energy conversion method in the vacuum chamber is heat radiation, the energy conversion efficiency is low and the degassing time is long, so the processing efficiency is low

Embodiment 1

[0036] The process parameters are as follows: set the working voltage to 1500V, the argon gas flow rate to 200Sccm, the power to 0.3KW, and the vacuum degree of the vacuum chamber to be 6.0E -2 Torr, the moving speed of the flexible substrate is 1.6m / min.

Embodiment 2

[0038] The process parameters are as follows: set the working voltage to 1500V, the argon gas flow rate to 450Sccm, the power to 0.45KW, and the vacuum degree of the vacuum chamber to be 5.8E -2 Torr, the moving speed of the flexible substrate is 1.45m / min.

[0039] The treatment effect is not only related to power and vacuum degree, but also related to the speed of the substrate. The slower the speed, the higher the processing energy per unit surface area, the faster the degassing, and the more obvious the surface modification. The surface modification effect can be judged by the dyne value. The dyne value of the substrate surface is less than 36 before being treated under the two process conditions of Example 1 and Example 2, and the dyne value of the substrate surface is greater than 56 after treatment.

Abstract

The invention discloses a surface processing device of a flexible base material. The surface processing device comprises a direct current power supply, a vacuum device, a transmission device, and a cathode plate and an anode plate arranged inside the vacuum device; the cathode plate is dead against the anode plate; the outer side of each pole plate is respectively provided with a cooling water pipe; each cooling water pipe comprises a water inlet pipe and a water outlet pipe, and a process air pipe is arranged at one side of the cathode plate dead against the anode plate. The heat generated from particle bombardment is directly acted on the flexible base material to bake and degas; separation of absorbed water on the surface of the flexible base material is fastened; the degassing effect of a flexible base material film is also increased when the degassing time is shortened, and the problem of low degassing efficiency caused by a traditional mode of transferring heat energy by radiation is overcome. Meanwhile, aggregate saturated organic covalent bonds of the flexible base material are activated into single-chain unsaturated covalent bonds due to bombardment of electrons on the flexible base material, and surface characteristics of the original flexible base material are changed.

Description

technical field [0001] The invention relates to the field of flexible substrate processing, in particular to a flexible substrate surface treatment device and treatment method. Background technique [0002] The preparation of composite films for touch screens of touch screen products is generally based on flexible substrates such as PET (Polyethylene terephthalate, polyethylene terephthalate) substrates, and the surface of the flexible substrates is treated before subsequent processing. Production Process. At present, the structure of the commonly used flexible substrate is HC (hard coating, hard coating) / PET, and the flexible substrate must be degassed before the later production process. [0003] The traditional degassing method for flexible substrates is to place the flexible substrate in a vacuum chamber without any treatment on the surface of the substrate, use an infrared heating tube to heat up, and transfer heat through radiation to achieve the purpose of degassing,...
