Problems solved by technology

At present, with people's in-depth research on release agents, silicone polymer resin emulsion dispersion system products have emerged as the times require, but their use costs are high, and there are certain environmental protection problems in the waste generated during the synthesis process
In addition, although some mold release agents have good mold release effects, they are prone to produce pores, powder and corrode the template.

Abstract

The invention discloses an architectural metal template release agent containing rosin modified silicone oil, and relates to the technical field of release agents. The release agent is prepared from the following raw materials in parts by weight: 15-20 parts of rosin modified silicone oil, 10-15 parts of bismaleimide resin, 10-15 parts of blast furnace slag, 8-12 parts of polyvinyl butyral, 6-11 parts of polyvinyl chloride paste resin, 5-9 parts of active magnesium oxide, 3-6 parts of polyvinylidene chloride, 3-6 parts of tricetyl phosphate, 2-4 parts of rubber powder, 2-4 parts of perfluorooctylethyl alcohol, 1-2 parts of poly-silicic-ferric sulfate, 1-2 parts of aluminum-magnesium silicate, 0.5-1 part of bone char, 0.5-1 part of dicyclopentadienyl iron, 0.3-0.5 part of isoquinoline and 0.3-0.5 part of nickel fluoride. A protective film formed on the surface of a template by the release agent has excellent waterproof property, corrosion resistance, impermeability and wear resistance, has a good release effect, and can effectively prevent concrete corrosion and template wear.

Description

[0001] Technical field: [0002] The invention relates to the technical field of release agents, in particular to a release agent for architectural metal templates containing rosin-modified silicone oil. [0003] Background technique: [0004] 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.
