Abstract

The invention relates to a concrete surface retarder and a preparation method thereof.The concrete surface retarder comprises the following raw materials: 10-20% of an oil phase, 70-85% of a liquid retarder, 2-8% of a nonionic emulsifier, 1-2% of a thickener and 0.05-0.1% of a preservative, a high-molecular polymer is completely adopted to achieve thickening and retarding of a carrier, the stability of the product is improved, and the viscosity of the product is reduced. The permeation, water retention and retarding effects are enhanced, and the flushing effect is excellent.

Description

technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a concrete surface retarder and a preparation method thereof. Background technique [0002] At present, my country's prefabricated buildings are developing rapidly. Among them, multi-purpose and various types of component products often need to be brushed. The previous manual brushing method is time-consuming and labor-intensive, and also causes dust pollution, which is undoubtedly contrary to the green environmental protection concept of prefabricated buildings. The appearance of the surface retarder just solves such problems. By painting the surface of the concrete, waiting for the concrete to be demolded, and scouring with a high-pressure water gun, a neat brushing interface can be obtained, which is easy to operate, reduces labor costs, and improves work. Efficiency, green safety and environmental protection. [0003] CN112299741A discloses a concrete surface retar...
