Mortar additive and preparation process thereof
The mortar additive comprises a water reducing agent, a thickening agent and a water-retaining agent, and the water reducing agent is prepared from, by weight, 10-20 parts of methyl allyl polyoxyethylene ether, 8-14 parts of isobutenol polyoxyethylene ether, 2-6 parts of adipic acid, 10-15 parts of hydrogen peroxide, 5-12 parts of acrylic acid, 5-10 parts of sodium hydride, 5-10 parts of ferrous sulfate, 10-18 parts of VC and 60-65 parts of deionized water. According to the invention, the methylallyl polyoxyethylene ether and the isobutylene alcohol polyoxyethylene ether are uniformly distributed on a molecular chain, so that the water reducer can be gradually released and uniformly adsorbed on the surface of cement particles, thereby avoiding the problem of too high adsorption speed, and the adipic acid and the acrylic acid regulate the flexibility of the molecular chain and the distribution of adsorption groups. The adsorption process is more stable, the water reducing effect is ensured, the adsorption speed of the water reducing agent is stabilized, and the consistency of concrete performance and the controllability of the construction process are ensured.
本发明公开了一种砂浆添加剂，包括减水剂、增稠剂和保水剂，所述减水剂由以下重量份的原料组成：10‑20份甲基烯丙基聚氧乙烯醚、8‑14份异丁烯醇聚氧乙烯醚、2‑6份己二酸、10‑15份双氧水、5‑12份丙烯酸、5‑10份氢化钠、5‑10份硫酸亚铁、10‑18份VC和60‑65份去离子，本发明中，甲基烯丙基聚氧乙烯醚和异丁烯醇聚氧乙烯醚均匀分布在分子链上，使减水剂能够逐步释放并均匀吸附于水泥颗粒表面，从而避免了吸附速度过快的问题，己二酸和丙烯酸调控了分子链的柔韧性及吸附基团的分布，使吸附过程更为平稳，保证了减水效果的同时，还稳定了减水剂的吸附速度，确保了混凝土性能的一致性和施工过程的可控性。
