Dry-mixed mortar and preparation method thereof
The invention discloses a dry-mixed mortar and a preparation method thereof. The dry-mixed mortar comprises, by weight, 80-100 parts of cement, 60-80 parts of modified quartz sand, 1-3 parts of redispersible latex powder, 5-10 parts of an epoxy resin curing agent, 8-15 parts of fly ash and 0.5-1 part of an external additive. The preparation method of the dry-mixed mortar comprises the following steps: mixing quartz sand with different particle sizes, adding a silane coupling agent, carboxymethyl cellulose, sodium lignin sulfonate and deionized water, and drying to obtain the modified quartz sand; dissolving the epoxy resin in an organic solvent, sequentially adding a curing agent and an accelerant, uniformly mixing, and curing to obtain the epoxy resin curing agent; and preparing the dry-mixed mortar by uniformly stirring and mixing all the components. Through the compounding synergistic effect of all the components, the prepared dry-mixed mortar is high in adhesive property and lasting and stable in adhesive property, and has the characteristics of being long in lasting time and not prone to falling off when being applied to ceramic tile adhesion.
本发明公开了一种干粉砂浆及其制备方法，按重量份数计，所述干粉砂浆包括以下组分：水泥80‑100份、改性石英砂60‑80份、可再分散乳胶粉1‑3份、环氧树脂固化剂5‑10份、粉煤灰8‑15份及外添加剂0.5‑1份；一种干粉砂浆的制备方法包括：将不同粒径的石英砂进行混合，加入硅烷偶联剂以及羧甲基纤维素、木质素磺酸钠和去离子水，干燥，制得改性石英砂；将环氧树脂溶解于有机溶剂，依次加入固化剂和促进剂混合均匀，固化，制得环氧树脂固化剂；将各组分搅拌混合均匀，制得干粉砂浆。本发明通过各组分的复配协同作用使制得的干粉砂浆粘结性能强，粘结性持久稳定，应用于瓷砖粘结，具有持久时间长，不易脱落的特点。
