Abstract: In this paper， a polymer emulsion with a viscosity of 1 478 MPa/s was synthesized by using reclaimed acrylic distillation liquid（MMA）as the main raw material at 82 ℃ ，stirring speed of 550 r/min，initiator（potassium persulfate）content of 0. 4%，and MMA∶butyl acrylate（BA）2∶3. Using the emulsion as adhesive，the real stone paint was prepared by adding hydroxyethyl cellulose 0. 14%，film forming agent 0. 67%，defoamer 0. 08%，distilled water 17. 44%，and natural colored sand 75. 32%. The water resistance of the stone-like paint meets the requirements of GB/T 1733—1993. The alkali resistance meets the requirements of GB/T 9265—2009. The temperature resistance also meets the requirements of JG/T 24—2000.

Key words: acrylic distillation liquid, polymer emulsion, real stone paint
