Abstract

The invention relates to a preparing method for environmental compound adhesive remover, belonging to technical field of preparing adhesive remover. The method comprising the following steps: (1) mixing the activated sludge with sodium persulfate and other materials and standing, collecting the supernatant, heating the supernatant, filtering, collecting filtrate, heating the filtrate after concentrating, mixing with sulfuric acid solution, cooling, mixing with sodium hydroxide solution, getting the modified humic acid mixture; (2) mixing the mixture with home-made mixed enzyme, glycerin monostearate and other materials, getting the adhesive removing binder; (3) mixing the binder with sodium stearate, sodium chloride and other materials, getting the environmental compound adhesive remover. The environmental compound adhesive remover which is made by the method does not contain dichlorotoluene and other hazardous materials. The adhesive remover cannot pollute the environment and threaten the health of operator. The adhesive remover has high adhesive removing efficiency and the efficiency can reach to more than 99%. The remover can be applied in the field of glass glue, excess glue after decoration, self-adhesive glue for pad pasting etc.
