Formula and preparation method of ALC (autoclaved lightweight concrete) plate repairing mortar
The invention discloses a formula and a preparation method of ALC plate repair mortar, the formula comprises water and powder according to a weight ratio of 0.2: 1, the powder comprises the following components by weight: 25% of white cement, 10% of heavy calcium powder, 64% of yellow sand, 0.25% of hydroxypropyl methyl cellulose ether, 0.15% of wood fiber, 0.55% of latex powder, and 0.05% of starch ether, the mark number of the white cement is PW42.5, the mark number of the heavy calcium powder is 0.1%, the mark number of the yellow sand is 0.1%, the mark number of the hydroxypropyl methyl cellulose ether is 0.1%, and the mark number of the starch ether is 0.1%. The coarse whiting powder is 325-mesh coarse whiting powder, the size of a sieve hole is 0.045 mm, the yellow sand is screened by a 50-100-mesh sieve, and the latex powder is DA-1200 type redispersible latex powder. The ALC board repairing mortar has the advantages of good scraping performance, good wettability, good construction performance, good sagging resistance, high bonding strength, good bonding performance with a base layer and an aerated concrete wallboard, good flexibility, less hollowing and shedding, freeze thawing resistance and good aging resistance.
本发明公开了一种ALC板材修补砂浆的配方及制备方法，配方包括重量比为0.2:1的水和粉料，所述粉料由以下重量百分比的组分组成：白水泥25％，重钙粉10％，黄砂64％，羟丙基甲基纤维素醚0.25％，木质纤维0.15％，乳胶粉0.55％，淀粉醚0.05％，白水泥的标号为PW42.5，重钙粉采用的是325目重钙粉，筛孔尺寸为0.045mm，黄砂通过50～100目的筛网筛选，乳胶粉采用的是DA‑1200型可再分散性乳胶粉。该ALC板材修补砂浆的批刮性好，湿润性好，施工性能佳，抗垂挂性好，粘接强度高，与基层和加气混凝土墙板均有良好的粘结性能，柔韧性好，少空鼓脱落，耐冻融、抗老化性能佳。
