Concrete air entraining agent
The invention discloses a concrete air entraining agent, and relates to the technical field of air entraining agents, and the concrete air entraining agent is prepared by the following steps: S1, putting raw materials into an enamel reactor according to a certain weight ratio, and stirring; s2, putting a reactant obtained in the step S1 into a reaction kettle, cooling, stirring, adding a vulcanizing agent, keeping the temperature, and carrying out a continuous reaction, so as to obtain the sulfide. According to the invention, alkylbenzene is used as a main raw material, and a sulfide obtained after a vulcanization reaction can fully activate a cementing material in concrete, promote a hydration reaction and improve the cohesive force, so that the defect that the strength is reduced due to introduction of bubbles into the concrete is overcome; and after the additive is added into newly mixed cement paste, mortar and concrete, the bubble film wall is thicker, a good spherical shape can be kept, and the mixture is high in cohesiveness, easy to pump and easy to vibrate and compact.
本发明公开了一种混凝土引气剂，涉及引气剂技术领域，包括以下步骤制备完成，S1将原料按照一定的配重比放入搪瓷反应器中进行搅拌，搅拌的过程中对温度进行控制直至反应完全后使用回流冷凝器进行回流再将物料洗涤放入蒸馏塔中蒸馏，S2将S1得到反应物放入反应釜中进行冷却，冷却后搅拌并加入硫化剂，并让温度保持进行持续反应得到硫化物。本发明使用烷基苯为主要原料，在进行硫化反应后得到的硫化物能充分将混凝土中胶凝材料激活，促进水化反应，提高粘结力，克服了混凝土中引入气泡而导致强度降低的缺陷，并且在新拌水泥浆、砂浆和混凝土里加入后会使其气泡膜壁较厚，能保持良好的圆球状，拌合物粘聚性强、易泵送、易振捣密实。
