Problems solved by technology

[0011] However, even if the dirt absorbing sheet of Patent Document 3 can absorb the oil on the surface of the handrail, it cannot absorb the oil on the guide roller inside, and it cannot remove the dirt and dust adhering to the handrail and the guide roller, or firmly adhere to the handrail and the guide roller. Dirt, dust on the handrails, guide rollers, so sometimes the handrails get dirty right away

Embodiment 1

[0063] According to the following steps (a) to (c), the conveyor handrail sticking film of the present invention was produced, and each property of "adhesive force", "adhesive residue", "floating", and "stain absorption" was evaluated.

[0064] (a) Using a single-screw T-die extruder with a laminating device having a screw diameter of 100 mm, a fully hydrogenated product of 100 mass % styrene-butadiene random copolymer (Asahi Manufactured by Kasei Chemicals Corporation, S.O.E. SS9000: styrene content 70 wt%, hydrogenation rate 100%) was molded into a substrate layer 1 having a thickness of 80 μm.

[0065] (b) On one side of the substrate layer 1, apply an acrylic water-based adhesive (manufactured by Nippon Shokubai Co., Ltd.: SKE-4851, main component: (methyl ) 2-ethylhexyl acrylate, glass transition temperature: -30°C) and epoxy-based cross-linking agent (manufactured by MITSUBISHI GAS CHEMICAL COMPANY, INC.: TETRAD-C) and dried 110 μm paper separator (Sumika Made by Conver...

Embodiment 2 and 3

[0081] Except changing the adhesive force of the adhesive layer A and the adhesive layer B, the same scheme as Example 1 was adopted. All characteristic values ​​were evaluated as good, and the target thin film was obtained.

Embodiment 4

[0083] Using an ethylene-vinyl acetate copolymer film (manufactured by Hayashi 12 Co., Ltd., E003: vinyl acetate content 17 wt %) as the substrate layer 1, coated with an acrylic water-based adhesive (manufactured by Showa High Molecular Co., Ltd.) as the adhesive layer B : SE-4500, main components: butyl (meth)acrylate, glass transition temperature -25°C) and epoxy crosslinking agent (manufactured by MITSUBISHI GAS CHEMICAL COMPANY, INC.: TETRAD-C), in addition, A thin film was produced by the same procedure as in Example 1. The adhesive force of the adhesive layer A was 1 N / 10 mm, and the adhesive force of the adhesive layer B was 0.3 N / 10 mm. All characteristic values ​​were evaluated as good, and the target thin film was obtained.

Abstract

A film adapted to be attached to a conveyor handrail, the film being configured to be attached to the conveyor handrail and used to remove dirt and dust on the handrail and a guide roller by moving the conveyor handrail. A film adapted to be attached to a conveyor handrail, the film being used as a double-sided dust-removing adhering film for cleaning the conveyor handrail and a guide roller for the handrail.  The film comprises a base layer (1), an adherent layer (A) superposed on one surface of the base layer (1) and caused to adhere to the surface of the conveyor handrail, and an adherent layer (B) superposed on the other surface of the base layer (1) and having an adhesion force less than the adhesion force of the adherent layer (A).

Description

technical field [0001] The invention relates to a sticking film for a handrail of a conveyor. More specifically, it relates to a conveyor handrail sticking film usable as a cleaning decontamination double-sided adhesive film for a conveyor handrail and a guide roller of the handrail. Background technique [0002] Handrails of passenger conveyors called escalators and moving walkways play an important role in realizing the safety of users. Dirt and dust adhere to the handrail due to the contact of the user, and it is unhygienic to leave the dirt and the like as it is. In addition, dirt and dust are also attached to the guide rollers of the handrails present inside the escalator. Therefore, handrails should be cleaned frequently to keep them clean. [0003] The handrail is generally formed of a rubber belt or a polyurethane belt so that it does not slip even if touched by a user. The cleaning method of the handrail is generally to use neutral detergent, silicone liquid, or...
