Preparation method of acid and alkali resistant and frost resistant adhesive sticker adhesive

The invention discloses a preparation method of an acid and alkali resistant and frost resistant adhesive sticker adhesive. The preparation method comprises the following steps: (1) washing polyethylene glycol terephthalate plastic; (2) drying and smashing to obtain a base material; (3) preparing a mixed solvent; (4) weighing the base material to be added into a reaction tank, adding natural rubber powder, urea resin powder and the mixed solvent, quickly stirring for dissolution, adding a plasticizer and an emulsifying agent, and stirring uniformly; and (5) adding a water-retaining agent and auxiliary materials into the reaction tank, and stirring uniformly to obtain the adhesive. According to the preparation method, the polyethylene glycol terephthalate plastic is taken as the base material, the natural rubber and urea resin are taken as auxiliary materials, the raw materials are low in price, the preparation cost is low, and the preparation process is simple; the natural rubber is resistant to acid and alka
