Problems solved by technology

As an auxiliary material for components, release agents have been widely used in the concrete industry as early as more than ten years ago. Although there are many existing concrete release agents, domestic release agents for component production have not really replaced foreign ones. The reason for the imported mold release agent is that it greatly reduces the adhesion between the component and the steel mold during the concrete pouring process, which not only easily causes the appearance of the component to be damaged, but also causes the adhesion between the component and the mold, making it difficult to remove the formwork and increasing the labor intensity , low production efficiency, difficult to clean the mold,

Abstract

The invention relates to a concrete member molding functional auxiliary material and a preparation method thereof, in particular relates to an environment-friendly concrete member release agent and a preparation method thereof and belongs to the technical field of chemical engineering. The concrete member molding functional auxiliary material is mainly prepared from a mold-releasing oil and water in a weight ratio of 1: 2 to 1: 8, wherein the mold-releasing oil is composed of, by weight percent, 20%-60% of synthetic ester oil substances, 70%-30% of grease, 1%-10% of membrane reactants, 0.5%-15% of an interface separant, 5%-15% of an emulsifier and 0.1%-0.5% of a defoamer. The environment-friendly water-based emulsion release agent special for demolding a concrete member is high in biodegradation rate, environmental friendly and non-toxic, and due to the adoption of advanced reactive film forming technique, the environment-friendly water-based emulsion release agent has the advantages of good demolding effect, smooth member surface, no lots of pores, no ash flying on surface layer, no residue in the steel mold, convenient cleaning of concrete, and no corrosion, possibly caused by the release agent, to the steel mold, and the like.
