The invention discloses adhesive mortar, which is prepared from the following raw materials in parts by weight: 50-80 parts of ordinary Portland cement, 10-20 parts of medium sand, 20-30 parts of fine sand, 0.5-1.2 parts of polylactic acid, 2-5 parts of modified corn starch, 0.1-0.5 parts of cellulose ether, 2-5 parts of acrylate emulsion, 5-10 parts of metakaolin and 40-60 parts of water, the preparation method of the modified corn starch comprises the following steps: preparing corn starch into corn starch turbid liquid with the concentration of 25%, adding octenyl succinic anhydride with the concentration of 6% into the corn starch turbid liquid, carrying out a modification reaction at 45 DEG C, drying, and crushing to obtain the modified corn starch. By adding polylactic acid and modified corn starch, the viscosity, viscosity and flexibility of the adhesive mortar are enhanced, daily use of people is facilitated, and by adjusting the ratio of cement to different sand particles, the mortar has enough strength and has good durability, water retention and fluidity.
本发明公开了一种粘结砂浆，其原料按照重量份计包括：普通硅酸盐水泥50‑80份、中砂10‑20份、细砂20‑30份、聚乳酸0.5‑1.2份、改性玉米淀粉2‑5份、纤维素醚0.1‑0.5份、丙烯酸酯乳液2‑5份、偏高岭土5‑10份、水40‑60份，其中，所述改性玉米淀粉的制备方法为：将玉米淀粉配制成浓度25％的玉米淀粉浊液，然后加入浊液6％的辛烯基琥珀酸酐45℃下进行改性反应，干燥、粉碎即得改性玉米淀粉。本发明其通过添加聚乳酸、改性玉米淀粉，增强了粘结砂浆的粘稠度、粘度和柔韧性，有利于人们日常使用，再通过调整水泥与不同砂颗粒之前的比例，使砂浆产生足够的强度，具有良好的耐久性、保水性和流动性。
