Abstract

The invention provides a high-performance stamp gum cleaning agent. The high-performance stamp gum cleaning agent comprises the following components in percentage by weight: 20-40% of turpentine, 10%of n-heptane, 10% of absolute ethyl alcohol, 15-60% of naphtha, 0-5% of a cellulose acetate butyrate solution and 0-50% of mixed acid dimethyl ester. According to the high-performance stamp gum cleaning agent disclosed by the invention, cellulose acetate butyrate is used as a film-forming substance; naphtha is adopted as a main solvent; absolute ethyl alcohol, n-heptane and turpentine are adoptedas auxiliary solvents; after a stamp is soaked with the stamp gum cleaning agent, the solvents with the naphtha as a main component can rapidly permeate into a gap between the stamp and an envelope and reach the interior of a glue film so as to separate the glue film from the back face of the stamp, and at the moment, the glue film can be rapidly stripped; and meanwhile, the glossiness of the stamp and the chromaticity of the pattern color can be kept unaffected through the film-forming substance. The high-performance stamp gum cleaning agent is simple in preparation method and convenient to use.
