In the present invention, styrene-acrylic emulsion specification used is: vitrification point 8～12 DEG C.
In the present invention, dispersant used can be traditional sodium acrylate dipersant, polyurethane dispersant etc., preferably, in order to have good dispersion and mixed type energy, dispersant used is carboxylic acid sodium salt form dispersant PS-5000, and it consists of the mixture of polycarboxylic acids sodium and water (44: 56).
In the present invention, described defoamer is organic silicon defoamer, and its defoaming capacity is strong, and surface tension is low, and chemical stability is good, is conducive to the stability that liquid powder mixes.
In the present invention, cement used is ash concrete, it is preferred to 42.5 ash concretes, has good adhesion strength；Described Kaolin is the high-activity nano Kaolin of 200-325nm particle diameter, not only there is good electrical insulating property and resistant to chemical media, and improve the reactivity of powder, simultaneously because its special microstructure, make liquid material component can enter in the microstructure of powder, increase the intersection compound between liquid material and powder, form inierpeneirating network structure, product comprehensive mechanical property is greatly improved.
In the present invention, described water reducer is naphthalene system or poly carboxylic acid series water reducer.
In the present invention, described early strength agent is calcium formate, it is preferred to commercially available high-purity (being not less than 95%) calcium formate；Described water-retaining agent is high viscosity methylhydroxypropylcellulose ether HPMC, and its viscosity profile is 10000-20000, it is preferable that viscosity 15000.
Accordingly, the preparation method that the invention also discloses flexible cement-base waterproof coating, comprise the following steps:
1. by styrene-acrylic emulsion, dispersant, defoamer, water, stirring obtains liquid material component；
2. the stirrings such as cement, quartz sand, silica flour, Kaolin, water reducer are obtained powder component.
Above-mentioned preparation process at room temperature carries out, and stirring incorporation time controlled at 0.5-1 hour.
On this basis, the invention also discloses the using method of flexible cement-base waterproof coating, with powder component, liquid material component is mixed use, mixing match is 1: 2-3, in mass.
Preferably, the mixed proportion of the two is 1: 2.5.
The experiment that applicant carries out shows, the cement group water-proofing material of the present invention has good hot strength and adhesion strength, and has good pliability.
