Abstract

The invention relates to external wall putty, which comprises two components of A and B according to following weight percentage: component A comprises 30-40 percent of heavy calcium carbonate, 5-15 percent of talcum powder, 25-35 percent of quartz sand, 25-30 percent of Portland, 42.5 of cement, 1-3 percent of subdividable latex powder, 0.2-0.5 percent of ethoxyl methyl cellulose ether, and 0.02-0.1 percent of modified starch ether; component B is 5-12 percent of crylic acid latex; assorting ratio of component A and B is 100:5-12. The external wall putty has the advantages that cracks and pores can be padded; after hard drying, the product is characterized by strong adhesion force, good water resistance and corrosion resistance, smooth surface layer, crack control, and good impact resistance; after tested, 0.8 MPa is reached under a standard state in terms of bond strength; after five times of freeze-thaw cycles, bond strength of the putty reaches 1.03 MPa; the putty can be extensively applied to alteration and face lifting of external walls, which provides smooth underside base material for applying dope.

Description

Exterior wall putty
Technical field
The invention belongs to building material field, relate to a kind of pair of component exterior wall putty.
Background technology
Present exterior wall putty has varied, is mainly used in cement wall surface, mixes the earth metope, and intensity does not wait.Exterior wall putty is to some ceramic tile metopes, when the mosaic metope carries out renewal and reform, and there are defectives such as sticking power is not strong, water tolerance is relatively poor in putty.
Summary of the invention
The object of the invention just provides a kind of strong adhesion, and water tolerance is fabulous, the putty that suitable exterior wall is used.
The present invention can realize in the following manner: exterior wall putty is by forming according to following weight percentage calculation A, two components of B: the A component is 30~40% water-ground limestones, 5~15% talcum powder, 25~35% quartz sands, 25~30% Portlands, 42.5 cement, 1~3% redispersable latex powder, 0.2~0.5% hydroxyethylmethyl-cellulose ether, 0.02~0.1% treated starch ether; The B component is 5~12% ACRYLIC EMULSIONs; The A component is 100: 5~12 with the ratio that cooperates of B component.
Described water-ground limestone is 250~500 orders.
Described talcum powder is 250~500 orders.
Described quartz sand 100~150 orders.
Water-ground limestone is a kind of important stable inorganic environment-friendly stopping composition; Top layer smooth feeling after lubricated sense of talcum powder increase construction and putty are done something in disregard of obstacles; The quartz sand water regain is low, improves workability, increases the impact strength after the doing something in disregard of obstacles of aggregate; Portland 42.5 cement are a kind of hydraulicity bonds, increase putty intensity, and the sticking power function; Redispersable latex powder increases putty water tolerance and intensity, is prone to construction, anti-cracking performance; Hydroxyethylmethyl-cellulose ether increases putty water-retentivity and thickening, and anti-cracking is prone to workability; Treated starch ether increases the putty anti-sag, and anti-cracking is prone to workability.ACRYLIC EMULSION can improve cement base products intensity, weather resistance, snappiness, wearability and sticking power and the LV emulsion that designs.
Exterior wall putty of the present invention is suitable for the surface of wall of mosaic, ceramic tile, marble, grouan, brick, can fill up the crack aperture, has strong adhesion after product is done something in disregard of obstacles; Water tolerance and wearability are good, smooth, the anticracking in top layer, good impact resistance characteristics; Putty of the present invention is through detecting, and on cohesive strength, standard state is issued to 0.8MPa; Behind freeze-thaw cycle 5 times, the cohesive strength of putty reaches 1.03MPa, the cohesive strength under the state that is above standard; Embody the performance that has good weather and overcome external stress, can be widely used in external wall reconstruction renovation, for the use of coating provides soft and smooth bottom surface base material.
Embodiment
Below in conjunction with embodiment, the present invention is done further description, but it is not represented as unique embodiment of the present invention.
Embodiment one
The A component is 30 kilograms of orders, 250 order water-ground limestones, 5 kilogram of 500 order talcum powder, 35 kilogram of 100 order quartz sand, 28.48 kilograms of Portland 42.5 cement, 1 kilogram of redispersable latex powder, 0.5 kilogram of hydroxyethylmethyl-cellulose ether, 0.02 kilogram of treated starch ether;
The B component is 12 kilograms of ACRYLIC EMULSIONs;
A component and B component composition one cover are made two component exterior wall putties.
Embodiment two
The A component is 31.7 kilogram of 500 order water-ground limestone, 15 kilogram of 250 order talcum powder, 25 kilogram of 150 order quartz sand, 25 kilograms of Portland 42.5 cement, 3 kilograms of redispersable latex powders, 0.2 kilogram of hydroxyethylmethyl-cellulose ether, 0.1 kilogram of treated starch ether;
The B component is 5 kilograms of ACRYLIC EMULSIONs;
A component and B component composition one cover are made two component exterior wall putties.
Method of use of the present invention:
1, use preceding the preparation:
Remove with jet of water that all relax, are prone to come off, flecked material, treat the top layer airing after, just can construct; Also other instrument such as available iron hammer is beaten lax material and is become broken and remove, and for putty uses construction a clean surface is provided.
2, combination process:
Pour 20~30 kg water in 5~12 kilograms of B components into, add double centner A component and constantly stirring again, prevent that the A component from forming powder ball; Under 30 ℃, this mixing material still can use in 3 hours.
3, construction:
After the mixing material for preparing left standstill 5~10 minutes; Paint cutter and trowel is constructed; Carry out second time recoat after doing something in disregard of obstacles as required, or carry out recoat as required the 3rd time, the gauge control of every time construction is in 0.5mm; Polish flat after 2 days, just can carry out coating application in the above.
