Abstract

The invention discloses a concrete demolding agent and a preparation method thereof and relates to the technical field of building materials. The concrete demolding agent includes, by weight, 20-50% of an oil substance, 1-5% of a thickener, 40-70% of deionized water, 0.1-0.5% of a preservative, 1-3% of a whitening agent, and 1-3% of an odor covering agent. The oil substance includes one or more ofengine oil, saponified oil and lubricant oil. The preparation method includes: S1) weighing the oil substance, thickener, deionized water, preservative, whitening agent and odor covering agent according to the weight percentages; S2) placing the deionized water and thickener in a stainless steel container and mixing and stirring the components for 10-20 min; S3) adding the oil substance, preservative, whitening agent and odor covering agent to the mixture, and mixing and stirring the components for 15-25 min; S4) performing filling package. The concrete demolding agent has good stability andis prepared from the engine oil and other additives in less quantity, so that the product is simple in component, is convenient to prepare and is low in cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete release agent and a preparation method thereof. Background technique [0002] Concrete release agent refers to a substance that is applied to the construction formwork before concrete pouring, so that the formwork will not stick to the concrete surface after pouring, making it difficult to remove the formwork, or affecting the smoothness of the concrete surface; its main function is on the formwork It forms a film with the concrete surface to isolate the two, also known as a release agent. [0003] There are many types of concrete release agents currently used, some use waste engine oil and finished engine oil, some use powder and other items to add, and a small amount of prepared release agents are used, all of which have different quality defects. Using waste engine oil, there is a large amount of residue on the concrete surface during the construction pr...
