Embodiment 1

[0047] figure 1 It is a figure which shows the process of the manufacturing method of the friction roller of this invention which concerns on Example 1. As shown in this figure, in process A1, the metal rotating shaft is attached to both ends of CFRP1 which formed the hollow cylindrical shape with a predetermined diameter. Supports flange 2 and prepares for molding. Next, in step B1, above the CFRP 1, the spray device 3 in which a plurality of nozzles 3a are arranged in a row is disposed. The spraying device is connected to a pump 4 and then to a mixer 5 .

[0048]Taking epoxy resin as a thermosetting resin as an example, on the above-mentioned mixer 5, a main agent tank 6 storing the main agent and a curing agent tank 7 storing a curing agent which is mixed with the main agent to start curing are connected. , There is also a conductive material tank 8 for storing the conductive material mixed with the main agent and the curing agent.

[0049] The raw materials mentioned a...

Embodiment 2

[0054] Figure 4 The process of the manufacturing method of the rubbing roller of this invention of Example 2 is shown, and the thicker conductive epoxy resin layer 11 is formed on the surface of CFRP1, and the member which can improve rigidity is formed. At the same time, the unevenness of the surface of CFRP 1 does not affect the conductive epoxy resin layer 11, and the conductive epoxy resin layer 11 has a smooth surface.

[0055] In the method of embodiment 2, utilize Figure 4 The process shown performs molding processing, and a molding cylinder 13 is used as shown in the figure. The molding cylinder 13 is a hollow cylindrical member made of high corrosion-resistant steel such as stainless steel, its two ends are open, and the inner peripheral surface is coated with, for example, polytetrafluoroethylene, that is, Teflon (registered trademark), to form a hollow cylinder. mold layer.

[0056] At the lower end of the above-mentioned molding cylinder 13, as Figure 5 A se...

Abstract

The invention aims to achieve light weight of roller cores adapting no metal reinforcement tubes, without self-weight deflection, and to form high-rigidity rubbing rollers, thereby enhancing the critical rotating speed during the friction. In addition, static electricity generated along with the friction can be easily discharged to the outside, and meanwhile, no metal plating layers are formed, thereby avoiding the generation of verdigris which is harmful to liquid crystal display elements. The rubbing roller of the invention is such a rubbing roller that is applied in the alignment process of an alignment film, where switch elements or electrodes on the surface are covered to form the liquid crystal display elements of the alignment film. A piece of rubbing cloth is pasted on a surface of a conductive thermosetting resin layer which is formed on the surface of cylindrical carbon-fiber reinforced plastics.

Description

technical field [0001] The present invention relates to a rubbing roll used in an orientation treatment process which is a part of the production process of a liquid crystal display element, and a production method thereof. Background technique [0002] The basic structure of a liquid crystal display element is to form a switching element and an electrode that control the alignment of liquid crystal molecules on the surface by applying a voltage, and two liquid crystal display element substrates that form an alignment film that gives a pretilt angle to the liquid crystal molecules on the upper surface. The switching elements and electrodes are spaced apart from each other by scattered gaskets and fixed by sealing material. Further, a liquid crystal layer is provided in a portion surrounded by the sealing material and the two liquid crystal display element substrates, and a polarizing plate is provided on the outer surface of each liquid crystal display element substrate. In...
