Abstract
The invention discloses an efficient method for removing a wallpaper sheet by peeling off a wall body surface to which the wallpaper sheet is adhesively bonded as well as a wallpaper remover solution used in the method for wetting the wallpaper sheet to facilitate peeling. The remover solution contains, as the essential ingredients, (A) a silicone-based surface active agent which is an organopolysiloxane modified with polyoxyalkylene or polyhydric alcohol residues and (B) a moisturizing agent which is typically a polyhydric alcohol or a alkoxyalkanol compound each in a specified concentration of 40-80% by weight, the balance being water as the solvent.
Claims14
A uniform wallpaper remover solution comprising:
- 0.01%-10% by weight of a silicone-based surface active agent;
- wherein the silicone-based surface active agent is a polyoxyalkylene- or polyhydric alcohol-modified organopolysiloxane compound having, in a molecule, at least one polyoxyalkylene residue or polyhydric alcohol residue as a pendant to the silicon atom in the organopolysiloxane molecule, and the content of the polyoxyethylene residue or polyhydric alcohol residue in the polyoxyalkylene- or polyhydric alcohol-modified organopolysiloxane compound is in the range of 40%-80% by weight;
- and
- from 0.1%-30% by weight of a moisturizing agent,
- the balance to 100% by weight being water.
A method for removing a wallpaper sheet adhesively bonded to the surface of a wall body with intervention of an adhesive layer, comprising:
- (a) applying, to the surface of the wallpaper sheet, the wallpaper remover solution comprising:
- 0.01%-10% by weight of a silicone-based surface active agent;
- and
- 0.1%-30% by weight of a moisturizing agent,
- the balance to 100% by weight being water;
- so as to wet the wallpaper sheet therewith;
- (b) soaking the adhesive layer with the wallpaper remover solution penetrating the wallpaper sheet so as to soften the adhesive layer;
- and
- (c) peeling the wallpaper sheet off the wall body surface.
A uniform wallpaper remover solution, comprising:
- 0.01%-10% by weight of a silicone-based surface active agent;
- wherein the silicone-based surface active agent is a polyhydric alcohol-modified organopolysiloxane compound having, in a molecule, at least one glycerin residue as a pendant to the silicon atom in the organopolysiloxane molecule;
- 0.1%-30% by weight of a moisturizing agent;
- and
- the balance to 100% by weight being water.
A uniform wallpaper remover solution, comprising:
- 0.01%-10% by weight of a silicone-based surface active agent;
- wherein the silicone based surface active agent is a polyhydric alcohol-modified organopolysiloxane compound having, in a molecule, at least one polyhydric alcohol residue as a pendant to the silicon atom in the organopolysiloxane molecule, wherein the polyhydric alcohol is of the formula:
- wherein the subscripts s and t are each a positive integer not exceeding 20;
- 0.1%-30% by weight of a moisturizing agent;
- and
- the balance to 100% by weight being water.
