The invention relates to a preparation method of high-strength bonding mortar. The preparation method comprises the following steps: step 1, weighing materials; step 2, quartz sand, diatomite, slag powder and mica powder are subjected to ball milling and mixing to obtain a ball milling material, the ball milling material is stirred, in the stirring process, emulsion resin is firstly added and uniformly stirred, then a separant is added and uniformly mixed to obtain a pretreated material, then the pretreated material is fed into a drying chamber to be subjected to vacuum drying, and a first composite material is obtained; step 3, uniformly mixing and stirring Portland cement, hollow glass beads and active zeolite powder to obtain a mixture, adding epoxy resin into the mixture, continuously stirring, adding bentonite, and uniformly stirring to obtain a second composite material; 4, uniformly stirring and mixing the first composite material and the second composite material, adding a modified flame retardant, cellulose ether, polypropylene fibers and a water reducing agent, and uniformly mixing to obtain high-strength bonding mortar; the bonding strength and compressive strength of the mortar are improved.
本发明涉及一种高强度粘接砂浆的制备方法，包括以下步骤：步骤1、称取物料；步骤2、将石英砂、硅藻土、矿渣粉和云母粉进行球磨混合，获得球磨物料，将球磨物料进行搅拌，搅拌过程中，先加入乳液树脂搅拌均匀后，再加入隔离剂混合均匀，获得预处理物料，之后送入干燥室内抽真空干燥，获得第一复合料；步骤3、将硅酸盐水泥、空心玻璃微珠和活性沸石粉混合搅拌均匀，获得混合料，向混合料内加入环氧树脂继续搅拌，加入膨润土搅拌均匀，获得第二复合料；步骤4、将第一复合料和第二复合料搅拌混合均匀后，加入改性阻燃剂、纤维素醚、聚丙烯纤维、减水剂混合均匀，获得高强度粘接砂浆；本发明提高了砂浆的粘接强度和抗压强度。
