Clear release agent for large area

Abstract

The invention provides a clear release agent for large area, which is characterized in that the clear release agent is mainly fixed by gasoline, alcohol, ceresin wax and new concept concrete surface beautifying release agent Lishi 50 (water solution type) produced by Kao Chemical Corporation Shanghai, wherein the mass ratio thereof is as follows: 60-80 parts of the gasoline, 8-20 parts of the alcohol, 10-30 parts of the ceresin wax and 3-10 parts of Lishi 50. The clear release agent for large area is nontoxic, tasteless, economic, environment-friendly, and convenient for production and use; can lead an exposed concrete preformed unit produced thereby to meet the requirements of surface air bubbles, crackles, planeness and fineness; shortens the construction period; and saves the cost of secondary decoration.

Description

technical field [0001] The invention relates to building construction industry materials. Background technique [0002] When producing concrete components, a layer of release agent should be applied on the inner surface of the formwork, so that the components can be separated from the formwork smoothly when the formwork is removed, and the surface appearance quality of the components is also guaranteed. Traditionally, oil-based release agents or saponin water-based release agents are generally used, but traditional release agents cannot eliminate the color difference on the surface of components, and inevitably there will be air bubbles, the surface finish is low, and the quality standards cannot be met, so they are not suitable for fair-faced concrete components. production requirements. At present, Lishi release agent is used in the production of concrete components, which can achieve good results when applied to components with a small area (not greater than 1m×2m), but ...

AI Technical Summary

Problems solved by technology

Traditionally, oil-based release agents or saponin water-based release agents are generally used, but traditional release agents cannot eliminate the color difference on the surface of components, and inevitably there will be air bubbles, the surface finish is low, and the quality standards cannot be met, so they are not suitable for fair-faced concrete components. production requirements

At present, Lishi release agent is used in the production of concrete components, which can achieve good results when applied to components with a small area (not greater than 1m×2m), but it can be applied to components with a larger area, such as stadium stands (equal to or greater than 1m×5m), the effect is not good: bubbles appear, the surface finish is low
