Abstract

The invention relates to a concrete release agent comprising the following components in percentage by mass: 10%-15% of perfluorinated alkyl ethylene oxide, 10%-25% of fatty alcohol-polyoxyethylene ether, 12%-19% of a complexing agent, 14%-20% of n-butyl acetate, 6%-12% of formic acid, 8%-16% of methylphenol, 9%-15% of sodium metasilicate, 3%-8% of diethylstilbestrol, 6%-14% of acetone, 9%-15% of cyclohexanone, 6%-15% of potassium hydroxide, 3%-17% of etidronic acid, 40%-60% of pure water, and 8%-10% of a tribromosalicylaniline, triethanolamine and glycerinum mixture, wherein the weight ratio of tribromosalicylaniline to triethanolamine to glycerinum in the mixture is 2 to 7 to 1. The concrete release agent disclosed by the invention is capable of playing roles in protecting a template, improving the appearance quality of concrete, enhancing the surface smoothness of the film, and the like.

Description

technical field [0001] The invention belongs to the field of coatings for decoration and relates to a concrete release agent. Background technique [0002] Concrete release agent is also called concrete release agent or release lubricant. It is a substance that is applied to the inner wall of the formwork to lubricate and isolate, so that the concrete can be smoothly separated from the formwork when the formwork is removed, and the shape of the concrete is kept intact. Compared with the traditional mold release material engine oil or waste engine oil, the release agent has the advantages of easy mold release, no pollution to the concrete surface, no corrosion of the formwork, easy painting, and low price. However, not all types of concrete release agents are suitable for templates made of various materials. For templates of different materials and concrete with different construction conditions and finishing requirements, a suitable release agent must be selected to recei...
