Waterproof dry-mixed mortar and production process thereof
The invention discloses waterproof dry-mixed mortar and a production process thereof, and belongs to the technical field of mortar production. The dry-mixed mortarcomprises the following components in percentage by weight: 40%-60% of ordinary Portland cement, 30%-50% of mixed sand, 1%-1.5% of redispersible polymer rubber powder, 0.2%-1.2% of an organic silicon waterproof agent, 0%-0.3% of fibers, 0.6%-1.5% of a water-retaining thickening agent and the balance of an additive. The dry-mixed mortaris prepared through the following processes: screening all components of the mixed sand through a screening device, performing metering according to a ratio, and then performing mixing; metering and mixing the starch ether, the cellulose ether and the bentonite according to the proportion to obtain a water-retaining thickening agent; metering and mixing ordinary Portland cement, screened and mixed sand, redispersible polymer rubber powder, an organic silicon waterproof agent, fibers, a water-retaining thickening agent and an additive according to a ratio to prepare a dry mixture; and dispersing and packaging the dry mixture to obtain a finished product. The performance of the mortar in all aspects is improved, a certain raw material cost can be saved, construction is convenient, the waterproof performance and the cracking resistance are excellent, and the durability is good.
本发明公开了砂浆生产技术领域的一种防水干混砂浆及其生产工艺，包括以下粉料，组分以重量百分比计为：普通硅酸盐水泥40％‑60％、混合砂30％‑50％、可再分散聚合物胶粉1％‑1.5％、有机硅类防水剂0.2％‑1.2％、纤维0％‑0.3％、保水增稠剂0.6％‑1.5％、余量为外加剂；并通过下述工艺制得：通过筛分装置筛选混合砂的各组分，并按配比计量而后混合；将淀粉醚、纤维素醚和膨润土按配比计量混合得到保水增稠剂；将普通硅酸盐水泥、筛选混合后的混合砂、可再分散聚合物胶粉、有机硅类防水剂、纤维、保水增稠剂、外加剂按配比计量并混合制得干混料；将干混料分散包装为成品；本发明提高了砂浆的各方面性能，可节省一定原料成本，便于施工，防水性能和抗开裂性能优异，且耐久性好。
