Description
Technical field
The present invention relates to a kind of building water-proof coated material, relate to more specifically cement-base flexible waterproof mortar.
Background technology
At present, water-proof material is numerous, can be divided into flexible water and rigid waterproofing two large classes.Facts have proved for many years in external, traditional flexible waterproof material such as coiled material and coating, although have flexibility characteristics, weather resistance is also better, but a little less than basal plane concrete binding power, cohesive strength is low, and is insecure with the basal plane bonding, is prone to joint, and easily aging, work-ing life is short, is prone to the phenomenons such as cracking, seepage, affects the normal use of buildings.
Summary of the invention
First technical problem to be solved by this invention is: provide a kind of composition simple, do not contain a kind of emulsion for the preparation of the waterproof rubber cement of formaldehyde.
For addressing the above problem, the technical solution used in the present invention is: a kind of emulsion for the preparation of the waterproof rubber cement consists of by mass fraction: terpolymer 25-50 part, ACRYLIC EMULSION 20-30 part.
Described terpolymer by vinylchlorid, ethene, vinyl acetate in molar ratio 2-2.6:1-1.2:5-6 be polymerized.
The number-average molecular weight of described terpolymer is 3000-4500.
Described emulsion is pressed mass fraction, and preferred group becomes: terpolymer 30-35 part, ACRYLIC EMULSION 25-28 part.
Second technical problem to be solved by this invention is: a kind of cement-base flexible waterproof mortar aging, long service life that is difficult for is provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of cement-base flexible waterproof mortar, by described emulsion, form with powder, and emulsion is 1-1.2:1.5-2 with the powder quality ratio.
Described powder consists of by mass fraction: 70-140 purpose sandstone 20-45 part, 425
#Aluminosulfate cement 48-55 part.
Described powder is pressed mass fraction, and preferred group becomes: 70-140 purpose sandstone 35-40 part, 425
#Aluminosulfate cement 50-52 part.
Both independently deposit emulsion, powder, need on-the-spot preparation during use, and compound method is:
1) in mass ratio 1-1.2:1.5-2 preparation of emulsion and powder adds container with emulsion, adds while stirring powder, adds complete after, continue stirring 5min;
2) leave standstill 2-3min after, stir into uniform thick shape rubber cement;
The judging criterion that stirs: rubber cement is without powder ball; When slurry is done the movement of falling object, can become a unremitting straight line;
3) preparation rubber cement total amount is calculated by every square meter matrix consumption 1.0Kg-1.5Kg.
The invention has the beneficial effects as follows:
1) elasticity is high, and has snappiness;
2) strong cohesiveness;
3) have good weathering resistance, resistance to deterioration;
4) do not contain formaldehyde.

Report number: FS028-090009
The use range of cement-base flexible waterproof mortar of the present invention:
1) ground of concrete, masonry walls, the body of precoating, light cinder brick formation;
2) indoor and outdoor building masonry wall, Infrastructure, grain depot, parking lot, tunnel, roof, ground, mouth of pipe node, swimming pool, kitchen, toilet, balcony, water reservoir etc.
The using method of cement-base flexible waterproof mortar of the present invention and precaution:
1) processing base level
Check the basal plane of waterproof layer, process defective, and clean out.Basal plane should be smooth, not dusting, non-scale, free from dust, without discrete particle, without greasy dirt, without defectives such as the obvious crack of hollowing and holes.
Built-in fitting should be finished before waterproof construction, around the tube wall, and inner corner trim, the foot of a wall, cracking place and floor drain etc. are the cracking position, needs to strengthen special processing, and drainage grade meets the requirements, and the negative and positive angular diameter is not less than the fillet slope angle of 30mm.
Crack treatment: need to cut basal plane and chisel into the V-type groove, and foreign material are cleaned out, tamp with the water-repellent cement rubber cement, spread one deck acid and alkali-resistance grid cloth and strengthen processing.
2) construction process
According to the quantity that once stirs and the thickness requirement once brushed, formation level is brushed.The each material that stirs of control is once finished on basal plane, to guarantee the accuracy of coat-thickness.
The coating that stirs generally brushes twice in plane when construction brushing, and coating requires evenly, can not holiday, should notice during brushing that firmly back and forth in length and breadth brushing can coat and reach even to guarantee concavo-convex place.Facade brushing construction should be brushed from bottom to top, and the coating that flows to inner corner trim should in time brush away, and avoids because piling up the blocked up cracking that causes.
Be used for moistureproof, moisture-proof barrier, require brushing twice, after the first pass construction, treat tentatively solid.Judge preliminary solid standard, the wall feel is dried, and shake-up can not come off and be as the criterion, and walks to destroy waterproof layer being as the criterion depending on the people, carries out the second construction again.
Waterproofing layer thickness is generally at 1.2-2mm.When construction brushing is about needing, the left and right sides is crisscross carries out.Should evenly brush during construction, show-through, holiday and packing phenomenon must not be arranged.
At the position that needs strengthen, such as negative and positive angle, drainage outlet, pipeline and Asiatic water closet pan periphery, new and oldly meet place, crack etc., but overbrushing is brushed twice of this product 1-2 as the waterproof enhancement layer.
Retaining test: when coating solid 72 hours, retaining 24 hours, ne-leakage point is qualified, namely waterproof system is finished.
3) precaution
Use temperature 0-40 ℃, must not construct in rain, snow and strong wind sky, and the greasy weather must again construction after dew receive to be done, and construct to rain in rear 2 hours or meet rain during construction and should take rainproof measure.
The coating that has stirred was finished in 1-2 hour.
Solid coating can not be added water again and stir use.
The above only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
