Heat-preservation and heat-insulation light mortar for building walls
The invention discloses heat-preservation and heat-insulation light mortar for a building wall. The mortar is prepared from the following raw materials: Portland cement, a cement modifier, expanded perlite, fly ash, 4-4 '-dimethyl biphenyl dicarboxylate, modified composite fibers, a lignin copolymer, vinyl acetate-vinyl versatate latex powder, styrene-butadiene emulsion, a composite water reducing agent, methyl cellulose ether and an expanding agent. The light anti-cracking plastering mortar is mainly used for improving the anti-cracking, reinforcing and toughening properties of the mortar, and the added substances are matched to form a polymer film with a three-dimensional network structure in the light anti-cracking plastering mortar, so that the internal structure of the light anti-cracking plastering mortar is improved, the freeze-thaw resistance of the mortar is improved, and the anti-cracking performance of the light anti-cracking plastering mortar is improved. In addition, the compression-bending ratio of the mortar is effectively reduced, so that the mortar shows good flexibility and crack resistance. The heat-preservation and heat-insulation light mortar for the building wall is high in bonding strength, good in water resistance, good in flexibility, high in shrinkage resistance, free of shrinkage during hardening, good in workability and small in elastic modulus, and meanwhile has a certain heat-preservation and heat-insulation effect.
本发明公开了一种保温隔热的建筑墙体轻质砂浆，所述砂浆原料包括硅酸盐水泥、水泥改性剂、膨胀珍珠岩、粉煤灰、4‑4'‑联苯二甲酸二甲酯、改性复合纤维、木质素共聚物、醋酸乙烯‑叔碳酸乙烯酯乳胶粉、丁苯乳液、复合减水剂、甲基纤维素醚、膨胀剂；着重于提升砂浆阻裂、增强和增韧的性能，所添加的物质之间配合作用在轻质抗裂抹面砂浆内部形成具有三维网状结构的聚合物薄膜，改善了轻质抗裂抹面砂浆的内部结构，不仅提高了砂浆的抗冻融性能，而且还有效地降低了砂浆的压折比，使砂浆表现出良好的柔韧性和抗裂性。本发明的保温隔热的建筑墙体轻质砂浆，粘结强度高、耐水性好、柔韧性好、抗收缩能力强、硬化时不收缩、和易性好、弹性模量小，同时具有一定的保温隔热效果。
