摘　　要：采用回收亚克力精馏液(MMA)为主要原料,在82℃、搅拌转速为550 r/min、引发剂(过硫酸钾)含量为0.4%、MMA/丙烯酸丁酯(BA)为2/3的条件下,合成了黏度为1478 MPa/s的聚合物乳液。利用该乳液作为胶黏剂,加入0.14%羟乙基纤维素、0.67%成膜助剂、0.08%消泡剂、17.44%蒸馏水、75.32%天然彩砂制备出真石漆。该真石漆的耐水性符合GB/T 1733—1993的要求,耐碱性符合GB/T 9265—2009的要求,耐温变性达到了JG/T 24—2000的标准要求。In this paper,a polymer emulsion with a viscosity of 1478 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.
