Anti-crack wallboard joint filling mortar
The invention relates to the technical field of joint filling mortar, in particular to crack-resistant wallboard joint filling mortar which comprises a base material, auxiliaries and water, and the base material is composed of Portland cement, natural sand, coal slag powder, fly ash, desulfurized gypsum powder, calcium carbonate powder and rubber particles. The auxiliary agent is prepared from bentonite, redispersible latex powder, polypropylene fiber, hydroxyethyl cellulose, a retarding type high-efficiency water reducing agent and a retarder, and finally, uniformly mixing the base material, the auxiliary agent and the water to obtain a joint filling mortar finished product. Compared with the existing inorganic cement-based joint filling material, the inorganic cement-based joint filling material disclosed by the invention has the prominent characteristics that the advantages of the existing organic and inorganic joint filling materials are well compatible, and the inorganic cement-based joint filling material not only has excellent crack resistance, but also has relatively high bonding strength, and also has the characteristics of low price, environment friendliness and long service life.
本发明涉及填缝砂浆的技术领域，是一种一种抗裂型墙板填缝砂浆，其包括基料、助剂、水，基料由硅酸盐水泥、天然砂、煤炉渣粉、粉煤灰、脱硫石膏粉、碳酸钙粉末、橡胶颗粒构成，助剂由膨润土、可再分散乳胶粉、聚丙烯纤维、羟乙基纤维素、缓凝型高效减水剂、缓凝剂构成，最后将基料、助剂、水混合均匀，得到填缝砂浆成品。相比现有的无机水泥基填缝材料，本发明的突出特点在于，很好地兼容了现有有机与无机填缝材料的优点，不仅有优异的抗裂能力，还具有较高的粘结强度，同时还具有价廉、环保、长寿命的特点。
