Problems solved by technology

[0010] However, even if the dirt absorbing sheet disclosed in Patent Document 3 can absorb oil on the surface of the handrail, it cannot absorb oil on the inner guide rollers.
In addition, dirt and dust adhering to the guide rollers cannot be removed, and dirt and dust firmly fixed on the handrails and guide rollers cannot be removed, so the handrails may be stained immediately

Embodiment 1

[0079] A lamination film was produced by the following procedure, and "adhesive force" and "easiness of peeling" were evaluated.

[0080] Using an ethylene-vinyl acetate copolymer film (manufactured by Hayashi 12 Co., Ltd., E003: vinyl acetate content 17wt%, thickness 100 μm), acrylic is coated on one side of the substrate layer so that the thickness after drying becomes 20 μm Water-based adhesive (manufactured by Nippon Shokubai Co., Ltd.: SKE-4851, main component: 2-ethylhexyl ester, glass transition temperature -30°C) and epoxy-based crosslinking agent (manufactured by MITSUBISHI GAS CHEMICAL: TETRAD-C) The mixture was used as an adhesive layer A, and a dried paper separator sheet of 110 μm (manufactured by Sumika Kaishi Co., Ltd., SL-80KCD7) was bonded. On the reverse side of the substrate layer to which the adhesive layer A was bonded, an acrylic water-based adhesive (manufactured by Showa High Molecular Co., Ltd.: SE-4500, main components: butyl ester, glass Transition ...

Embodiment 2～9

[0103] It evaluated similarly to Example 1 except having changed the adhesive force of the adhesive layer A and the adhesive layer B into the value shown in "Table 1". The ease of peeling was evaluated as "good" under the conditions of (1) to (3), and peeling did not occur.

Embodiment 10～17

[0105] As shown in "Table 2", it evaluated similarly to Example 1 except having made the adhesive force of the adhesive layer B larger than the adhesive force of the adhesive layer A.

[0106] Table 2

[0107] Table 2

[0108]

[0109] In each of Examples 10 to 17, under the condition (1), peeling occurred and the evaluation was "impossible" or "defective", but by using a single-sided adhesive tape or a double-sided adhesive tape (condition (2) or condition (3)), can be improved to "good" to prevent peeling.

[0110] In addition, under the condition (4) that the adhesive layer B at the end of the laminated film is reversed to the surface side of the handrail (adhered body), when the adhesive force of the adhesive layer B is 0.9N / 10mm or more In Examples 10 to 17, peeling could be prevented.

Abstract

Disclosed is an adherent film (1) for a conveyor hand-rail, said film including a substrate layer (11), a first adherent layer (A) which is laminated on one surface of the substrate layer (11) and which is adhered to the surface of a conveyor hand-rail, and a second adherent layer (B) which is laminated on the other side of the substrate layer (11), with the adherent force of the second adherent layer (B) being at least equal to the adherent force of the first adherent layer (A). By adhering the adherent film (1) to a conveyor hand-rail and moving the conveyor hand-rail, dirt and refuse on the hand-rail and a guide roll can be removed.

Description

technical field [0001] The invention relates to a cleaning method for laminating films of conveyor handrails, conveyor handrails and handrail guide rollers. More specifically, it is related with the conveyor handrail bonding film etc. used as the dust removal double-sided bonding film for cleaning of the handrail of a conveyor, and the handrail guide roller. Background technique [0002] The handrails of passenger conveyors called escalators and moving walks play an important role in realizing the safety of users. Dirt and dust adhere to the handrail due to contact with the user, but it is unhygienic if the dirt and the like are left as they are. In addition, the handrail guide rollers inside the escalator will also adhere to dirt and dust. 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 as not to slip even if a user touches it. The cleaning method of the handrail i...
