Novel sculpture mortar dry powder and preparation method thereof
A novel sculpture mortar dry powder and a preparation method thereof, the novel sculpture mortar dry powder comprises 58-70 parts of Yellow River sand, 30-40 parts of cement, 17-27 parts of fly ash, and 0.9-1.9 parts of a self-made binder, and the preparation method comprises the following steps: S1, dissolving polyvinyl alcohol in 6-8 times by weight of water, adding a 30% hydrogen peroxide solution, carrying out a stirring reaction for half an hour, adding dextrin water slurry, carrying out a stirring reaction for half an hour, and carrying out a stirring reaction for half an hour; carrying out spray drying to obtain dextrin modified polyvinyl alcohol particles; s2, adding methyltrimethoxysilane into water of which the weight is 10-15 times that of methyltrimethoxysilane, stirring and dissolving, adjusting the pH value to 2-3, heating to 40-50 DEG C, hydrolyzing for 10-15 hours to obtain a cross-linked solution, adding hydroxypropyl methyl cellulose, stirring and uniformly mixing, and spray-drying to obtain silane modified hydroxypropyl methyl cellulose; and S3, uniformly mixing the products obtained in S1 and S2 according to the mass ratio of (10-15): 1 to obtain the self-made adhesive. The stone-like and wood-like products prepared from the sculpture mortar have the advantages of convenience in operation, good workability, few cracks, stable quality and the like while raw materials are saved and the cost is reduced.
一种新型雕塑砂浆干粉及其制备方法，由黄河砂58‑70份，水泥30‑40份，粉煤灰17‑27份，自制粘合剂0.9‑1.9份组成，制作步骤如下：S1、将聚乙烯醇加入重量为6‑8倍的水中溶解，加入30%过氧化氢溶液，搅拌反应半小时，加入糊精水浆液，搅拌反应半小时，喷雾干燥得糊精改性聚乙烯醇颗粒;S2、将甲基三甲氧基硅烷加入重量为10‑15倍的水中搅拌溶解，调节pH至2‑3，升温至40‑50℃水解10‑15h，得交联溶液，加入羟丙基甲基纤维素，搅拌混匀，喷雾干燥，得硅烷改性羟丙基甲基纤维素;S3、将S1和S2所得产品按照质量比10‑15∶1的比例混合均匀，得到自制粘合剂。本发明的雕塑砂浆制作的仿石、仿木产品，在节约原料，降低成本的同时，具备操作方便、和易性好、裂缝少、质量稳定等优点。
