Abstract
An object is to provide: an adhesive remover capable of sufficiently removing an adhesive from a material; and a method for removing an adhesive with use of the adhesive remover. The object is attainable by an adhesive remover that contains oil and a surfactant, the oil containing at least one selected from the group consisting of a specific vegetable oil, a specific ester oil, an aliphatic carboxylic acid, and a mineral oil, the surfactant containing an anionic surfactant and/or a nonionic surfactant that has an HLB of more than 5 and is liquid at room temperature.
Claims13
An adhesive remover for removing an adhesive from an article which includes a super absorbent polymer and to which the adhesive adheres,
- the adhesive remover comprising oil and a surfactant,
- the oil containing at least one selected from the group consisting of a vegetable oil, an ester oil, an aliphatic carboxylic acid, and a mineral oil,
- the vegetable oil having an iodine value of 70 to 160,
- the ester oil having not more than three ester groups per molecule,
- the surfactant containing an anionic surfactant and/or a nonionic surfactant that has an HLB of more than 5 and is liquid at room temperature.
An adhesive removal method, comprising an adhesive removal step of removing an adhesive from one or more materials to which the adhesive adheres, by immersing, in an adhesive remover containing oil and a surfactant, an article in which the one or more materials are bonded with use of the adhesive,
- the one or more materials including a super absorbent polymer,
- the oil containing at least one selected from the group consisting of a vegetable oil, an ester oil, an aliphatic carboxylic acid, and a mineral oil,
- the vegetable oil having an iodine value of 70 to 160,
- the ester oil having not more than three ester groups per molecule,
- the surfactant containing an anionic surfactant and/or a nonionic surfactant that has an HLB of more than 5 and is liquid at room temperature.
An adhesive remover for removing an adhesive from a super absorbent polymer or a nonwoven fabric to which the adhesive adheres, the adhesive remover comprising oil and a surfactant,
- the oil containing at least one selected from the group consisting of a vegetable oil, an ester oil, an aliphatic carboxylic acid, and a mineral oil,
- the vegetable oil having an iodine value of 70 to 160,
- the ester oil having not more than three ester groups per molecule,
- the surfactant containing an anionic surfactant and/or a nonionic surfactant that has an HLB of more than 5 and is liquid at room temperature.
