Polyether modified polysiloxane and preparation method thereof as well as organic silicon defoaming agent and preparation method thereof
The invention relates to the technical field of concrete admixtures, in particular to polyether modified polysiloxane and a preparation method thereof, and an organic silicon defoaming agent and a preparation method thereof. The organic silicon defoaming agent is prepared by stirring a mixture of polyether modified polysiloxane and an emulsifier mixed in water at the heating temperature of 60-90 DEG C, according to the present invention, the Si-O-C type polyether modified polysiloxane defoaming agent prepared by using the polyether modified polysiloxane has characteristics of good hydrolysis resistance and good long-term storage stability; when the concrete foaming agent is applied to concrete, the concrete workability is good, harmful bubbles in the concrete can be effectively eliminated, the foam homogenizing performance is good, the foam is finer and softer when the concrete foaming agent is applied to the concrete, the compressive strength of a concrete material can be effectively improved, and the service life of the concrete material is prolonged.
本发明涉及混凝土外加剂技术领域，特别涉及一种聚醚改性聚硅氧烷及其制备方法、有机硅消泡剂及其制备方法。该有机硅消泡剂由聚醚改性聚硅氧烷和乳化剂混合于水中的混合物，经60～90℃加热温度下搅拌处理制得；本发明提供的采用聚醚改性聚硅氧烷制得的Si‑O‑C型聚醚改性聚硅氧烷消泡剂，其具有良好的抗水解性和长期储存稳定性；并且其应用于混凝土中时，混凝土和易性好，可有效消除混凝土有害气泡，其匀泡性能好，应用于混凝土中使得泡沫更加细腻柔软，可有效提高混凝土材料的抗压强度，延长混凝土材料的使用寿命。
