Description

  The present invention is a laminate (so-called pressure-sensitive adhesive sheet) having a pressure-sensitive adhesive layer used exclusively for fixing an assembled wire for automobiles (hereinafter referred to as “wire harness”) to a molded ceiling (ceiling, headlining, roof lining). It is.

  In the assembly line of automobiles, as a component (unit, assembly, assembly) in which a wire harness is fixed in advance on the back side of molded parts for automobiles such as headlining, bumpers and door trims in order to reduce the required man-hours. It is made to supply.

  Conventionally, the wire harness is fixed to the back side of the head lining by a method of fixing with a hot melt adhesive, a method of fixing with a staple (a U-shaped nail or staple). However, in the case of a hot melt adhesive, the wire harness is fixed to the head lining after melting the adhesive at a high temperature using a special tool (for example, a glue gun). There was a possibility. In addition, since it takes time until the molten adhesive is solidified, there is a problem of poor working efficiency.

On the other hand, in the case of staples, since the needle is pierced in the head lining, there is a possibility that the staple may penetrate through to the opposite side, and there is a problem that requires skill in the work.
Then, the method of fixing a wire harness to the back surface side of a headlining using the adhesive sheet is proposed. As the pressure-sensitive adhesive sheet, a pressure-sensitive adhesive sheet having a base material made of a soft metal foil and a pressure-sensitive adhesive layer provided on the base material has been proposed (see Patent Document 1).

  However, in the fixing method using the pressure-sensitive adhesive sheet having the base material made of the soft metal foil and the pressure-sensitive adhesive provided on the base material, for example, a wire harness having a large outer diameter or a plurality of wire harnesses are used. When fixing with the pressure-sensitive adhesive sheet, or when fixing the wire harness along the uneven shape of the headlining, the pressure-sensitive adhesive sheet (the metal foil base material) There was a problem that it was easy to tear.

  In addition, the headlining is generally difficult to bond because it often uses a polyolefin-based or polyester-based material and sometimes uses a raised nonwoven fabric. Therefore, the adhesive sheet tends to be insufficiently adhered to the head lining, and there is a problem that the wire harness is peeled off from the head lining when the assembly having the wire harness fixed to the head lining is transported to an automobile assembly factory. .

  In addition, the Ministry of Land, Infrastructure, Transport and Tourism has formulated safety standards for road transport vehicles, and stipulates that flame retardant materials must be used in Article 20 (Boarding Equipment). In addition, the Ministry of Land, Infrastructure, Transport and Tourism published Annex 27 (Technical Standard for Flame Retardancy of Interior Materials) that stipulates the details of safety standards for road transport vehicles, and exemplifies ceilings as interior materials. From the viewpoint of safety considerations, it is considered desirable to use a flame-retardant pressure-sensitive adhesive sheet as the pressure-sensitive adhesive sheet used for the ceiling.

  In recent years, automobile manufacturers have been actively working on various environmental issues such as preventing global warming, improving the air environment, and building a recycling-oriented society. The Japan Automobile Manufacturers Association has formulated a method for testing the amount of volatile organic compounds (hereinafter referred to as VOC) emitted from the passenger compartment and a voluntary effort to reduce the amount of VOC emitted from the passenger compartment. In recent years, from the viewpoint of such environmental considerations, it has been demanded to reduce the amount of 13 volatile organic compounds including toluene. A large amount of toluene is used as a diluting solvent in the pressure-sensitive adhesive used in the pressure-sensitive adhesive sheet, and there is a problem that a part of toluene remains even after the toluene is dried at the time of manufacturing the pressure-sensitive adhesive sheet.

JP 2006-96856
