Abstract

Relating to the technical field of demoulding agent production, the invention discloses a building template demoulding agent for concrete pouring. The building template demoulding agent is prepared from the following raw materials by weight: 40-45 parts of modified silicone oil, 15-20 parts of polypropylene oxide glycol 2000, 8-12 parts of C9 petroleum resin, 6-10 parts of volcanic ash, 5-8 parts of sepiolite powder, 5-8 parts of ethylene-tetrafluoroethylene copolymer, 4-6 parts of toluene diisocynate, 3-5 parts of rapeseed cake, 2-3 parts of oleic acid polyoxyethylene ester, 2-3 parts of nano-alumina, 2-3 parts of glass fiber powder, 1-2 parts of tri-n-butyltin methoxide, 1-2 parts of sulfated castor oil, 10-15 parts of butyl acetate, and 10-15 parts of n-butanol. The demoulding agent provided by the invention can significantly improve the demoulding effect of concrete, prevents concrete from adhering to the template during demouling and protects the template and concrete surface structure. At the same time, the demoulding agent has no corrosion on the template, thus fully extending the service life of the template.

Description

Technical field: [0001] The invention relates to the technical field of release agent production, in particular to a building formwork release agent for concrete pouring. Background technique: [0002] Concrete molding needs to be fixed by building formwork, and the formwork needs to be removed after the concrete has formed a certain strength. In order to prevent the concrete from adhering to the formwork during the formwork removal process and increase the difficulty of handling the formwork, a release agent is usually sprayed on the inner wall of the formwork. The release agent acts as isolation and lubrication between the formwork and the concrete surface to overcome the bond between the formwork and the concrete surface, so that the formwork can be separated from the concrete when the formwork is removed, which not only keeps the shape of the concrete intact, but also protects the surface of the formwork damaged. [0003] Traditional building formwork release agents ar...
