Acid-corrosion-resistant repair mortar and preparation method thereof
The invention discloses acid-corrosion-resistant repair mortar and a preparation method thereof. The acid-corrosion-resistant repair mortar comprises a mixture A, a mixture B and water, wherein the mixture A comprises the following components in parts by weight: 28-35 parts of cement; 8-12 parts of a mineral admixture, 4-5 parts of gypsum, 54-58 parts of fine sand, and 0.5-0.7 part of organic fiber, the mixture B is prepared from the following components in parts by weight: 0.03 to 0.05 part of a thixotropic agent, 0.03 to 0.05 part of a thickening time control agent, 0.7 to 0.9 part of hydrophobic rubber powder, 0.05 to 0.07 part of a tackifying water-retaining agent, 0.03 to 0.04 part of a compacting agent, and 0.05 to 0.07 part of a high-performance water reducing agent, the ratio of the weight part of the water to the total weight part of the mixture A and the mixture B is 0.13-0.17, and the cement is any one of aluminate cement, a mixture of aluminate cement and Portland cement and a mixture of aluminate cement and phosphate cement. According to the invention, aluminate cement is used as a main cementing material, and hydrophobic rubber powder and a compacting agent are used as auxiliary materials, so that the acid-corrosion-resistant repair mortar is prepared.
本发明公开了一种耐酸腐蚀的修复砂浆及其制备方法，包括A混料、B混料和水；A混料包括以下组分及重量份数：水泥28‑35份；矿物掺合料8‑12份；石膏4‑5份；细砂54‑58份；有机纤维0.5‑0.7份；B混料包括以下组分及重量份数：触变剂0.03‑0.05份；调凝剂0.03‑0.05份；憎水型胶粉0.7‑0.9份；增粘保水剂0.05‑0.07份；密实剂0.03‑0.04份；高性能减水剂0.05‑0.07份；水的重量份数与A混料和B混料的总重量份数之比为0.13‑0.17；水泥为铝酸盐水泥、铝酸盐水泥与硅酸盐水泥的混合物和铝酸盐与磷酸盐水泥的混合物中的任意一种。本发明使用铝酸盐水泥作为主要胶凝材料，辅以憎水型胶粉和密实剂，制备出耐酸腐蚀的修复砂浆。
