Abstract
The invention discloses a cement whiskering inhibitor, which at least comprises: boric acid, activated carbon powder, tributyl phosphate, silicon micropowder, ferrous sulfate and kaolin. The cement efflorescence inhibitor can obviously improve the efflorescence resistance and durability of cement base materials under the condition of ensuring that the performance of cement mortar and concrete cement base materials is not reduced or is improved. Therefore, the quality, the aesthetic feeling and the durability of the appearance of the building are greatly improved, and the maintenance cost of the building is reduced.
Description
Technical Field
The invention relates to the field of building materials, in particular to a cement whiskering inhibitor.
Background
Ordinary concrete is silicate, silicate ions are subjected to hydrolysis reaction when meeting air or water vapor in a wall body, generated hydroxide is combined with metal ions to form hydroxide with low solubility (the chemical property is alkaline), the hydroxide is separated out from the wall body when the temperature rises, the hydroxide is separated out on the surface of concrete cement along with gradual evaporation of water, and the hydroxide accumulates over the month, so that the original decorative coating or paint and the like are jacked up and do not adhere to the wall surface any more, and whitening, peeling and falling occur, and the process is called as 'saltpetering'. The blank room can be directly separated out, the decorated blank room can be swelled, skinned and fallen off by coating, paint and the like. Does not fade for years and seriously affects the appearance.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
