本文研制了一种以固体微粒为核，有机高分子为壳的核－壳型乳液混凝土脱膜剂，并对产品性能进行了测定。实验结果表明，该脱模剂脱模效果好，可降低预制构件与模具间的粘附力，粘灰量少。可广泛用于钢模、木模、混凝土基隔离之用。 In this paper, a core-shell emulsion concrete mold release agent with solid particles as core and organic polymer as shell was developed. The properties of the product were measured. The experimental results show that the release agent has a good demolding effect and can reduce the adhesion between the prefabricated component and the mold, and the amount of sticky ash is small. Can be widely used in steel molds, wood molds, concrete-based isolation.
