Description
Technical field
The present invention relates to the concrete interface process field, be specifically related to a kind of water-based nonabsorbable interfacial agents.
Background technology
For the construction of cement-based self-leveling, the brushing of interfacial agents is a very important link.The purpose of brushing interfacial agents mainly comprises following 4 points: the one, to basic unit's sealing, avoid too much, the too fast suction of basic unit, and prevent that cement-based self-leveling mortar from losing moisture too early; The 2nd, the adhesion strength of enhancing basic unit and cement-based self-leveling mortar layer; The 3rd, prevent the generation of bubble; The 4th, improve the flowability of cement self-leveling mortar.Chinese patent CN02148424.4 discloses a kind of water base interfacial agents, and it is solvent (as carrier) with water, with natural animal glue and the certain technology of several auxiliary agent process, makes the aqueous solution.The maximum characteristics of this invention be exactly interfacial agents when concrete surface sprays, a part of interfacial agents is penetrated into inside concrete, a part is stayed concrete surface.When smearing mortar, this part interfacial agents of concrete surface is dissolved in the mortar, and after mortar solidified, concrete just formed firm integral body with mortar like this.Yet in some fine and close basic units, as ceramic tile, marble, terrazzo, this interfacial agents just can not well penetrate into basic unit, thereby influenced its caking property greatly, some substrate surface are smooth simultaneously, and surface tension is very low, and interfacial agents can not well form continuous film in this basic unit.Because these fine and close basal planes will increase construction cost greatly with artificial removing, common interfacial agents then is not suitable for nonabsorbable basic unit (in the transformation process of level ground, many once visited places, former terrace is that materials such as ceramic tile, terrazzo, terrace lacquer are nonabsorbable basic unit usually).
Summary of the invention
This technical problem to be solved is to provide a kind of water-based nonabsorbable interfacial agents, to solve in nonabsorbable basic unit problem such as making cement based self-leveling construction difficulty.Water-based nonabsorbable interfacial agents of the present invention has aqueous, environmental protective, advantage such as good caking property and film forming in nonabsorbable basic unit.The invention solves material and technological problems in the flat construction of flowing automatically on the nonabsorbable basal plane, for the transformation of nonabsorbable terrace has solved very big technical barrier.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of water-based nonabsorbable interfacial agents by weight percentage, comprises following component:
