The invention relates to a concrete surface retarder and a preparation method thereof. The raw materials of the product of the invention include 10-20% of an oil phase, 70-85% of a liquid retarder, 2-8% of a non-ionic emulsifier, and 1% of a thickener. ‑2%, preservative 0.5‑1‰, by completely adopting high molecular polymer to realize thickening and retarding carrier, the stability of the product is improved, its osmotic water retention retarding effect is enhanced, and the scouring effect is excellent. |
