Problems solved by technology

[0002] The common release agents for existing building templates are divided into two categories: one is mineral oil, its main disadvantage is that it has poor adhesion to the template, it is easy to pollute the concrete surface, it brings difficulties to further construction, and it can only be effective once; the other is It is emulsified oil, its main disadvantage is that it is easy to corrode the template, and it is easy to cause problems when removing the film, and because it is water-soluble, it cannot be used in winter, and it can only be effective once

Abstract

This invention is one kind of stripping lacquer specially used for building shuttering and its preparation method an dapplication, it belongs to painting product field. Stripping problem of building shuttering, especially steel quality building shuttering is solved. Its active component is fluoro resin, auxiliary materials as filler, colorant, accessory ingredient and solvent is used, they are got by grinding after blended, and few curing agent and diluting agent are added when it is used. It is coated on working face of building shuttering by brush coating or spray coating, and then paint film is formed after dried. The beneficial is that the stripping lacquer rust proof capability is strong, adhesive force is good, hardness is high. It doesní»t pollute concrete surface and template, and it is easy strip and the concrete surface is smooth and no scar after stripped. It can be used in all kinds of weather after once film forming, and it can reduce working cost, it is environmental protection at the same time.

Description

technical field [0001] The invention belongs to the field of paint products, and relates to a special release paint for building templates, a preparation method and application thereof. Background technique [0002] The common release agents for existing building templates are divided into two categories: one is mineral oil, its main disadvantage is that it has poor adhesion to the template, it is easy to pollute the concrete surface, it brings difficulties to further construction, and it can only be effective once; the other is It is emulsified oil, its main disadvantage is that it is easy to corrode the template, and it is easy to have problems when removing the film, and because it is water-soluble, it cannot be used in winter, and it can only be effective once. Contents of the invention [0003] Technical problem to be solved: provide a release paint with fluororesin as the active component, as a release agent for building templates, especially steel building templates...
