Reinforced wet-mixed mortar additive
The invention discloses a reinforced wet-mixed mortar additive, and belongs to the technical field of building materials. The additive comprises a water-retaining and thickening component, a water reducing agent, an air entraining agent, a retarder, a strengthening component, an anti-cracking agent, a defoaming agent and water. The functional components are scientifically proportioned, and the methyl hydroxyethyl cellulose ether and the polyacrylamide are alkalized and modified by the sodium chloroacetate, so that the thickening and water retention effects can be effectively improved, the solubility is improved, and the layering problem in a high-temperature environment is obviously improved. According to the invention, the EVA latex powder is pre-crosslinked to form small nano gel particles, and material pore channels are effectively blocked, so that material fracture caused by micro pore channels is avoided, and the strength and stability of the material are greatly improved. The raw materials cooperate with one another and have a synergistic effect, the positive effects of reducing the mixing amount, reducing the cost and remarkably improving the strength and stability of the material are jointly achieved, and the economic benefits are remarkable.
本发明公开一种强化型湿拌砂浆添加剂，属于建筑材料技术领域。本发明添加剂包括保水增稠组分、减水剂、引气剂、缓凝剂、强化组分、抗裂剂、消泡剂以及水。本发明科学配比各功能成分，本发明将甲基羟乙基纤维醚和聚丙烯酰胺，经过碱化和氯乙酸钠改性，可有效提升增稠保水效果，溶解度提高，明显改善高温环境下的分层问题。本发明将EVA乳胶粉进行预交联，形成小颗粒纳米凝胶颗粒，材料孔道进行有效的封堵，避免微小孔道导致的材料断裂，大幅提升材料强度和稳定性。本发明各原料相互配合，协同增效，共同实现了掺量降低，成本降低，材料强度和稳定性显著提升的积极效果，经济效益显著。
