Concrete release agent and preparation method thereof
The invention provides a concrete release agent and a preparation method thereof. Specifically, the concrete release agent comprises, based on the total weight thereof: 25-40 wt% of a base oil having a kinematic viscosity at 40 DEG C of between 1 and 20 mm2/s, the base oil being selected from mineral oil, synthetic oil or a combination thereof; 5 to 10 weight percent of nonionic polyurethane resin, wherein the nonionic polyurethane resin is a polymerization product of C6-10 dihydric alcohol and aliphatic diisocyanate; 0.5 to 2.5 wt% of an emulsifier; 1-2 wt% of a penetrant; 1 to 5 wt% of an antifoaming agent; 2-4 wt% of an antirust agent; and the balance of water. According to the embodiment of the invention, the concrete release agent has good release performance, the concrete subjected to release treatment by the concrete release agent has good self-curing capability in the curing process, and the finally cured concrete has enhanced mechanical performance.
本发明提供一种混凝土脱模剂及其制备方法。具体地，所述混凝土脱模剂基于其总重量包含：25‑40重量%的40℃运动粘度在1‑20 mm2/s之间的基础油，所述基础油选自矿物油、合成油或其组合；5‑10重量%的非离子型聚氨酯树脂，所述非离子型聚氨酯树脂是C6‑10二元醇与脂肪族二异氰酸酯的聚合产物；0.5‑2.5重量%的乳化剂；1‑2重量%的渗透剂；1‑5重量%的消泡剂；2‑4重量%的防锈剂；和余量的水。根据本发明的实施方案的混凝土脱模剂具有良好的脱模性能，经所述混凝土脱模剂脱模处理的混凝土在固化过程具有良好的自养护能力，并且最终固化得到的混凝土具有增强的机械性能。
