The invention provides a concrete tackifying type water reducing agent and a preparation method thereof, the tackifying type water reducing agent is composed of a water reducing agent component and a water retention type tackifier, the tackifier inner core is wrapped in a protective shell, and the cohesiveness and long-acting working performance of concrete can be enhanced when the phenomena of segregation, bleeding, bottom digging and the like occur in the concrete. Nano bentonite is taken as a main raw material, a protective shell is provided for the tackifier, the bleeding rate of the concrete is reduced on the premise of ensuring the fluidity of the concrete, the steps are simple, the cost is low, and the whole preparation process is safe, reliable, free of organic solvents, non-toxic, pollution-free and environment-friendly. The core-shell ratio and the coating ratio of the water-retaining tackifier are properly adjusted according to factors such as bleeding rate and working environment suitable for concrete, so that the final water reducer product has better adaptability, and good slump retaining performance is ensured.
本发明提供了一种混凝土增粘型减水剂及其制备方法，该增粘型减水剂由减水剂组分和保水型增粘剂组成，增粘剂内芯包裹在保护壳体中，再混凝土出现离析、泌水、扒底等现象时可以增强混凝土的粘聚性和长效工作性能。以纳米膨润土为主要原材料，为增粘剂提供保护壳体，在保证混凝土流动度的前提下，降低混凝土的泌水率，步骤简单、成本低廉，整个制备过程中安全可靠，不使用有机溶剂，无毒无污染，环境友好。根据适用混凝土的泌水率、工作环境等因素，适当调整保水型增粘剂的芯壳比、包覆比，从而保证最终的减水剂产品具有更好的适应性，以保证良好的保坍性能。
