Abstract
The invention discloses a color-variable adhesive. The color-variable adhesive comprises, by weight, 100 parts of a polyester resin or rubber, 5.0 to 9.0 parts of vinyl ether, 15.0 to 20.0 parts of a phenolic resin, 0.1 to 1.0 part of an epoxy resin, 0.01 to 0.03 parts of an indicator, and 0.01 to 0.03 parts of a fixing agent. The invention also discloses an adhesive tape coated with the color-variable adhesive. The indicator is sensitive to a pH value. The ether, the petroleum resin, isocyanate, the epoxy resin and the fixing agent anchor the indicator and provide a color change environment. When being coated or pasted on a target position, the adhesive tape can change color while change of a pH value of the environment thereby indicating the pH value, and then change its color again while re-change of the pH value. The adhesive tape can be reused and solves the technical problem that the existing pH value test paper cannot be used repeatedly for a long time.
