Efficient defoaming functional material and preparation method thereof
The invention relates to the technical field of chemical materials, in particular to an efficient defoaming functional material and a preparation method of the efficient defoaming functional material. Comprising the following raw materials: 5%-12% of modified polysiloxane, 5%-10% of polyether modified silicone oil, 5%-10% of alkynol, 1%-10% of an emulsifying component, 0.1%-4% of a thickening component, 0.1%-4% of an anticorrosive component and the balance of water. Modified polysiloxane, polyether modified silicone oil and alkynol are compounded to serve as main foam eliminating and inhibiting components, a fluorine element is introduced into the defoaming agent, meanwhile, polyether chain segments are grafted, surface tension is effectively reduced, dispersity in a concrete system is improved, alkynol is introduced to serve as the main foam inhibiting component, and the foam inhibiting effect is good. The foam removing and inhibiting agent is suitable for a concrete system to maintain beneficial small bubbles, the foam film breaking is accelerated through foam removing and inhibiting component compounding, and the foam removing and inhibiting performance in the concrete system is good, so that the working performance is improved, and the foam removing and inhibiting agent has important practical application value.
本发明涉及化工材料技术领域，特别涉及一种高效消泡型功能材料及其制备方法，以高效消泡型功能材料总质量作为参考，按照质量分数计算，包括以下组分的原料制成：5％‑12％改性聚硅氧烷、5％‑10％聚醚改性硅油、5％‑10％炔醇、1％‑10％乳化成分、0.1％‑4％增稠成分、0.1％‑4％防腐成分、余量为水。通过改性聚硅氧烷、聚醚改性硅油、炔醇复合作为主要消抑泡成分，在消泡剂中引入氟元素的同时通过接枝聚醚链段，有效降低了表面张力并提高了在混凝土体系中的分散性，并引入了炔醇作为主要抑泡成分，适用于混凝土体系保持有益的小气泡，通过消抑泡成分复合加快了泡膜的破裂，在混凝土体系中消抑泡性能良好，从而实现工作性能的提升，具有重要的实际应用价值。
