Facing mortar with adjustable humidity and preparation method thereof
The invention discloses facing mortar with adjustable humidity. The facing mortar comprises the following components: 5-20 parts of polymer surface grafted diatomite, 30-60 parts of cement, 2-10 partsof gypsum, 0.5-5 part of latex powder, 30-50 parts of quartz sand, 0.2-1 part of cellulose ether and 0.2-0.7 part of pigment. The polymer surface grafted diatomite is prepared by the following steps:(1) roasting diatomite; (2) carrying out alkali treatment on the calcined diatomite; and (3) grafting diatomite on the surface of the polymer. The diatomite is subjected to polymer modification through a surface grafting technology, so that the adsorption performance of the surface of the mortar is remarkably enhanced, and the effect of regulating and controlling the humidity is achieved; ordinary Portland cement and aluminate cement are compounded, so that the early strength of the mortar is improved, and the later strength of the mortar is also developed; the latex powder is added, so thatthe bonding performance of the mortar and a bottom-layer wall body is effectively improved, and the mortar is prevented from falling off and stripping from a base layer.
本发明公开了一种具有可调节湿度的饰面砂浆，包括以下组分：聚合物表面接枝硅藻土5‑20份，水泥30‑60份，石膏2‑10份，乳胶粉0.5‑5份，石英砂30‑50份，纤维素醚0.2‑1份，颜料0.2‑0.7份，其中，聚合物表面接枝硅藻土通过以下方式制备：（1）焙烧硅藻土，（2）碱处理煅烧后的硅藻土，（3）聚合物表面接枝硅藻土。本发明通过了表面接枝技术对硅藻土进行聚合物改性，显著增强砂浆表面的吸附性能，起到调控湿度的作用；采用普通硅酸盐水泥和铝酸盐水泥这两种水泥复合，提高了早期强度，也发展了后期强度。通过添加乳胶粉，有效提高了砂浆与底层墙体的粘结性能，防止砂浆产生从基层脱落剥离现象。
