AI Technical Summary

Problems solved by technology

When the coating contains materials such as ferrite, polypyrrole, silicon dioxide and other particles or flakes, it is easy to cause uneven composition when preparing the coating, and it cannot be used as a coating structure and good adhesion. Advantage
[0003] In the roller coating device of the prior art, the roller coating part is rigidly connected to the fixed part, so the adjustment of the gap between the roller coating part and the substrate to be coated becomes very important and difficult to control. If the control is not good, it will easily affect the coating thickness and uniformity

Embodiment 1

[0033] The preparation of embodiment 1 polypyrrole / ferrite coating

[0034] Such as figure 1 and figure 2 As shown, the roller coating device includes a driving part 4, a roller shaft 2, a plate substrate 6, a substrate fixing part 1 and a coating adding part 7 that can be used in conjunction with it. The bottom of the outer surface of the roller shaft is provided with a coating part 3, The roller shaft 2 is connected to the driving part 4 by a non-rigid connecting piece 5 . In an optional embodiment, the connecting piece 5 is an elastic connecting piece.

[0035] Because there is a non-rigid connection between the roller shaft and the driving part, during the roller coating process, the roller coating pressure and gap can be adjusted by the quality of the roller shaft, and the distance between the roller shaft and the plate substrate 6 can be adjusted by the gravity of the roller shaft. The gap prepared by roller coating is complete and uniform in thickness.

Embodiment 2～6

[0044] The preparation of embodiment 2~6 polypyrrole / ferrite coating

[0045] The preparation of the polypyrrole / ferrite coating is the same as in Example 1, only the thickness of the coated part of the roller coating device, the pressure between the roller shaft and the plate-shaped substrate, and the running speed of the roller shaft are adjusted. See Table 1 for details. .

Embodiment 7

[0047] It is basically the same as Embodiment 1, the only difference is that the connecting piece 5 of the roller coating device is a spring.

Abstract

The invention discloses a roller coating device, a roller coating method and application of the roller coating device and the roller coating method in preparation of a wave-absorbing coating. The roller coating device comprises a driving part, a roller shaft, a plate-shaped base material and a base material fixing part, a coating part is arranged on a part of the outer surface or the whole outer surface of the roller shaft; the driving part is in non-rigid connection with the roller shaft; the plate-shaped base material is horizontally laid and is fixed on the base material fixing part; the roller shaft is in contact with the to-be-roller-coated surface of the plate-shaped base material; and the driving part drives the roller shaft to move in the direction parallel to the surface to be subjected to roller painting. The prepared wave-absorbing coating is compact, controllable in thickness, high in consistency, good in wave-absorbing effect and high in corrosion resistance. The device is particularly suitable for preparing wave-absorbing coatings such as polypyrrole / ferrite and graphene / ferrite containing granular and / or flaky materials; and the preparation method is simple, easy to control, capable of achieving batch production, low in cost and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of coating preparation, and relates to a roll coating device and a roll coating method and their application in preparing wave-absorbing coatings. Background technique [0002] The methods of preparing coatings on the surface of the substrate generally include dip coating (also known as dipping), spray coating, roll coating (also known as coating or coating), wiping coating, chemical deposition, electrodeposition, physical deposition, etc., and for large areas , The method of preparing the coating on the surface of the flat substrate is the most widely used dip coating, spray coating and roller coating. When the coating contains materials such as ferrite, polypyrrole, silicon dioxide and other particles or flakes, it is easy to cause uneven composition when preparing the coating, and it cannot be used as a coating structure and good adhesion. Advantage. [0003] In the roller coating device of the prior art, the rol...
