Description
Technical field
The present invention relates to a kind of building water-proof paint, be specifically related to a kind of rapid-hardening polymer emulsion waterproof paint, belong to building material technical field.
Background technology
Building water-proof paint is the thick liquid macroimolecule synthetic materials that is at normal temperatures without solid shape, after coating, solidifies the rear general name that can form the material of tough and tensile waterproof coating in substrate surface by the volatilization of solvent or evaporation or the reaction of moisture.The kind of common waterproof paint has polyurethane water-proof paint, mono-composition poyurethane water-proof paint, polymer cement waterproof paint, polymer emulsion waterproof paint, pitch class waterproof paint and modifying asphalt class waterproof paint etc.
Through the development of over half a century, the properties of building water-proof paint has all obtained comprehensive raising, and it is friendly that environment becomes gradually; Yet, manual work or the main form of construction work of current waterproof paint that traditional blade coating, roller coat etc. are original, this form of construction work wastes time and energy, the became uneven of filming, difficult quality guarantee.Certainly, this also slowly is not suitable for spraying relevant with coating itself is dry, does not also pay attention to the coating application mode with the past, construction equipment is relevant.
The form of construction work of this backwardness for a change, the industry continuous rapid-hardening building water-proof paint of having developed suitable spraying application mutually in recent years is such as polyureas, rapid-hardening Rubber Modified Asphalt Waterproof Coating etc.So-called rapid-hardening building water-proof paint refers to coating from being ejected into the curing only 5 ~ 10s that do not flow, even shorter.Practice of construction shows that the spraying application advantage is numerous: the coating efficiency that (1) is high, spray efficiency are more than 10 times of conventional rollers construction up to per hour 500 ~ 1200 square metres; (2) splendid surface quality, spray-on coating is smooth, brilliance, densification, without brush mark, roller marks and particle; (3) prolong coating work-ing life, airless spraying can make coating particles go deep into the body of wall space, makes paint film and metope form mechanical snap, and the enhancing paint adhesion increases the service life; (4) turning, space and rough difficult brush portion position have been captured easily; (5) greatly saved coating.
On the other hand, the water-and acrylate waterproof paint has obtained a large amount of uses under construction, and it mainly contains two kinds of forms: polymer emulsion building water-proof paint, polymer cement waterproof paint; These two kinds of coating are by the slow volatilization of moisture, and film forming is overstock in the accumulation of each composition in the coating, and setting time is long, still adopts the form of construction work of roller coat, blade coating at present.Yet there are no at home at present the rapid-hardening water-and acrylate building water-proof paint that is fit to spraying application.
Summary of the invention
The object of the invention provides a kind of rapid-hardening polymer emulsion waterproof paint.
For achieving the above object, the technical solution used in the present invention is: a kind of rapid-hardening polymer emulsion waterproof paint, comprise host A component and solidifying agent B component, and the weight ratio of host A component and solidifying agent B component is 1:0.5 ~ 1;
By weight, described host A component comprises following component:

Above, described silicone antifoam agent can adopt the F111 defoamer of Qingdao bounties chemical industry company limited production or the SN345 defoamer of the auspicious specialization worker of Hangzhou card company sale etc.
Magnificent section 981 sanitass that described sanitas can adopt the auspicious specialization worker of Hangzhou card company to sell.
In the technique scheme, described mineral filler is 1000 ~ 1300 purpose talcum powder.Preferred 1250 purpose talcum powder.
In the technique scheme, described stablizer is superfine alumina silicate.
In the technique scheme, described softening agent is dibutyl phthalate or dioctyl phthalate (DOP).Be dibutyl phthalate (DBP) or dioctyl phthalate (DOP) (DOP).
In the technique scheme, described dispersion agent is aqueous dispersant.Such as AMP-95, DP-518 etc.
Preparation method and the using method of rapid-hardening polymer emulsion waterproof paint of the present invention can adopt following steps:
(1) preparation of solidifying agent B component: by proportioning silicate solutions, water are mixed, stirring gets final product;
(2) preparation of host A component: by proportioning macromolecule emulsion, softening agent, dispersion agent, sanitas, silicone antifoam agent are added stirring tank and stir, add stablizer again, mineral filler stirs, use at last 30% dilute sulphuric acid (quality proportioning) to regulate PH=4 ± 0.2 and get final product;
(3) use common A, B component being sprayed according to mass ratio 1:0.5 ~ 1 atomizing without the gas coating applicators on the market, the contact of two components got final product freezing film in rear 3 ~ 6 seconds.
Principle of work of the present invention is as follows:
Fs: when host A component and solidifying agent B component by without the gas coating applicators with vaporific ejection and when contacting, the H in the host
