In the present invention, benzene emulsion specification used is: second-order transition temperature 8 ~ 12 DEG C.
In the present invention, dispersion agent used can be traditional sodium acrylate dipersant, polyurethane dispersant etc., preferably, in order to have good dispersion and mixed type energy, dispersion agent used is carboxylic acid sodium salt form dispersion agent PS-5000, and it consists of the mixture of poly carboxylic acid sodium and water (44: 56).
In the present invention, described defoamer is silicone antifoam agent, and its defoaming capacity is strong, and surface tension is low, and chemical stability is good, is conducive to the stability of liquid powder mixing.
In the present invention, cement used is ash concrete, is preferably 42.5 ash concretes, has good cohesive 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 reactive behavior of powder, simultaneously due to its special microtexture, make liquid material component can enter into the microtexture of powder, increase the intersection compound between liquid material and powder, form inierpeneirating network structure, increased substantially product comprehensive mechanical property.
In the present invention, described water reducer is naphthalene system or poly carboxylic acid series water reducer.
In the present invention, described hardening accelerator is calcium formiate, is preferably commercially available high purity (being not less than 95%) calcium formiate; Described water-holding agent is high viscosity methylhydroxypropylcellulose ether HPMC, and its viscosity profile is 10000-20000, preferred viscosities 15000.
Accordingly, the invention also discloses the preparation method of flexible cement-base waterproof coating, comprise the following steps:
1. by benzene emulsion, dispersion agent, defoamer, water, stirs and obtains liquid material component;
2. cement, quartz sand, silica powder, kaolin, water reducer etc. are stirred and obtain powder component.
Above-mentioned preparation process is at room temperature carried out, and is uniformly mixed time controling at 0.5-1 hour.
On this basis, the invention also discloses the using method of flexible cement-base waterproof coating, by liquid material component and powder component used in combination, mixing match is 1: 2-3, in mass.
Preferably, the blending ratio of the two is 1: 2.5.
The experiment display that applicant carries out, cement group water-proofing material of the present invention has good tensile strength and cohesive strength, and has good snappiness.
