Polyether modified polysiloxane, preparation method of polyether modified polysiloxane, defoaming agent and preparation method of defoaming agent
The invention relates to the technical field of concrete admixtures, in particular to polyether modified polysiloxane and a preparation method thereof, and a defoaming agent and a preparation method thereof. The defoaming agent is prepared by stirring a mixture of an emulsifier, polyether modified polysiloxane and water at the heating temperature of 60-90 DEG C, the defoaming agent prepared from polyether modified polysiloxane has good hydrolysis resistance and long-term storage stability. When the foaming agent is applied to concrete, harmful bubbles in the concrete can be effectively eliminated, the size stability of the bubbles is good, the early flowing property of the concrete is good, the compressive strength of a concrete material is 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、消泡剂及其制备方法。该消泡剂由乳化剂、聚醚改性聚硅氧烷与水的混合物于60～90℃加热温度下，搅拌处理制得。本发明采用聚醚改性聚硅氧烷制备出的消泡剂，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，可有效消除混凝土有害气泡，泡沫的尺寸稳定性好，混凝土的早期流动性能良好，且混凝土材料的抗压强度得到提升，延长了混凝土材料的使用寿命。
