Description
Technical field
The present invention relates to pressure sensitive adhesion sheet, in detail, relate on the resin housing of household electrical appliances and electronics and can peel off after stickup, and as required can be just like the sheet of releasing pressure sensitive adhesive more again pasting as former state on this housing.
Background technology
Up to now, the pressure sensitive adhesion sheet that records this trade(brand)name and description of commodity, using method etc. on adhesive surface on the resin housing of household electrical appliances and electronics is to show, to sell.
In recent years, consider the recirculation of the resin housing of used household electrical appliances and electronics being reclaimed, being pulverized rear recycling from the viewpoint of saving resource.
Will be by the resin housing recirculation of household electrical appliances and electronics time, the in the situation that of being pasted with pressure sensitive adhesion sheet on this resin housing, there is the situation of this pressure sensitive adhesion sheet being peeled off to rear recirculation, also have the situation of recirculation under original state of pasting this pressure sensitive adhesion sheet.
When by pressure sensitive adhesion sheet when this resin housing strips down recirculation, require enough bounding forces to firmly fix within the time that pastes this resin housing, but also require pressure sensitive adhesion sheet to there is the releasable that can easily peel off in the time that this resin housing is peeled off.In addition, when stick on pressure sensitive adhesion sheet on this resin housing the direct recirculation of original state time, require the surface substrate of pressure sensitive adhesion sheet identical with the material of this resin housing.
That is, require pressure sensitive adhesion sheet to have and the bounding force of the bonded body such as resin housing and the character that can peel off again from bonded body, and then require its surface substrate to be made by the material identical with bonded body, wish that these conditions can meet.
On the other hand, as the pressure sensitive adhesive of releasable pressure sensitive adhesion sheet, considering from the viewpoint of environmental problem, is being that pressure sensitive adhesive changes to water system pressure sensitive adhesive from solvent.In the time being water system pressure sensitive adhesive, if can easily strip down from bonded body, also reduce with the closing force of the surface substrate that belongs to same material, so just produce pressure sensitive adhesive layer and remaining in the problem on bonded body.
Past, for paper, metal, the bonded body such as Plastic, pressure sensitive adhesion label pressure sensitive adhesive composition when bonded body is peeled off require pressure sensitive adhesion sheet to there is good cementability and can not remained on bonded body and can be peeled off again, as the pressure sensitive adhesion sheet that meets this target, someone once proposed on the surface of surface substrate lamination one by adding the pressure sensitive adhesion sheet that forms as the contact adhesive composition floor of the surfactant-based softening agent such as the polyoxyethylene nonylplenyl ether of softening agent in the aqueous pressure-sensitive adhesive composition of pressure sensitive adhesive (B) (with reference to patent documentation 1: JP 2000-281989 communique to containing binding property micropartical (A) and also containing as required.）。
In patent documentation 1, as surfactant-based softening agent, only use in an embodiment polyoxyethylene nonylplenyl ether, as another concrete example, the polyoxygenated alkyl phenyl ethers such as the polyoxyalkylene alkyl such as polyoxyethylene lauryl ether, polyoxyethylene stearyl base ether, polyoxyethylene two (stearyl) ether or thiazolinyl ethers, polyoxyethylene octyl phenyl ether, polyoxyethylene two (nonyl) phenyl ether, polyoxyethylene two (nonyl phenyl) ether in paragraph ［ 0058 ］, are only recorded.
But, collaboration the pressure sensitive adhesion sheet of pressure sensitive adhesive of these surfactant-based softening agent when bonded body is peeled off, the bounding force of surface substrate and pressure sensitive adhesive layer is abundant not, sometimes there is pressure sensitive adhesive composition and remain in bonding residual on bonded body, exist enough good problems of not talkative releasable.
Summary of the invention
