Abstract
The invention discloses an anti-cracking coating for external walls, which is mainly made of the raw materials according to the weight ratios of: 60-100 portions of white cement, 50-100 portions of white quartz sand, 1-4 portions of dispersible rubber powder, 0.1-1 portions of hydroxypropyl methylcellulose and 0.5-3 portions of water reducing agent. The anti-cracking coating is used for decorating external walls without fading, falling off, chapping, etc. conditions; besides, the coating can be directly coated at the surface of a cement mortar bed at the external walls and a lacquer putty layer is not needed between the cement mortar bed and the coating layer, thus changing coating process of external walls from the traditional three procedures into two procedures, shortening operation period and reducing construction cost.
Description
Technical field
The invention belongs to technical field of construction and decoration materials, particularly a kind of crack resisting coating for exterior wall.
Background technology
Wall decoration aspect outside the building, exterior wall tile once was an external wall decorative material fashionable for a time, meet the eye on every side in the streets and lanes in small towns, city all is the ceramic tile mosaic.Much zero scattered diffusing obscission has appearred in the buildings of the furring brick of founding a capital the 80s and 90s, even the incident of " face brick comes off and injures the pedestrian by a crashing object " also took place but As time goes on; Face brick also is inconvenient to keep in repair when bringing hidden danger to the resident, and mottled metope has a strong impact on the outward appearance of buildings and the image in city.And in recent years, along with the progressively popularization of building energy conservation cause, a lot of buildingss have all adopted exterior wall heat-preserving system, because the deadweight of exterior wall tile is bigger, weight capacity to lagging material is had relatively high expectations, and this has increased the cost of heat-insulation system virtually, and potential safety hazard is even more serious.Simultaneously, paste the heat-insulation system of exterior wall tile, also can cause after face brick comes off and tremble with fear, the heat preservation and energy conservation effects of influence building.In addition, exterior wall tile is in environmental protection, production, decoration, construction, all exist tangible deficiency to the aspects such as protection of building, and the consumption to Nonrenewable resources such as soil, coals is also quite big in process of production; Price is also higher comparatively speaking, has increased building cost.
Along with the guiding of technology rapid development such as exterior coating and emulsion paint and government's relevant policies, adopt exterior coating or emulsion paint to carry out the buildings finishing and accepted by each side more and more and be used widely.Exterior coating or the emulsion paint technology that adopts needs three process usually at present: 1, use cement sand plaster, whole process need survive (bottoming, levelling, cover) three times; 2, putty layer survives for two times (bottoming, repair); 3, roller coating coating or emulsion paint survive (bottoming, repair) for two times, and promptly final wall face forms cement sand bed, putty layer, dope layer or latex enamelled coating three-decker altogether.This coating or emulsion paint Technology complexity, needed construction period is longer, and is bigger to the job schedule influence.If directly carry out coating or mopping after adopting traditional cement sand plaster, then owing to the present reason of aspects such as technology, material, coating or emulsion paint itself is bad attached to weather resisteant behind the wall face, fade easily, even produce dope layer or emulsion paint decortication, phenomenon such as peel off; And metope easily produces be full of cracks in the future, the infiltration phenomenon occurs.
Summary of the invention
The purpose of this invention is to provide a kind of new decoration of exterior wall crack resisting coating.This crack resisting coating is used for decoration of exterior wall and is not prone to and fades, come off and phenomenon such as be full of cracks; And can be at the direct coating of sand-cement slurry laminar surface of exterior wall, making exterior coating technology is two procedures by traditional three process saving, shortens construction period, reduces building cost.
Another object of the present invention provides a kind of preparation method of above-mentioned crack resisting coating for exterior wall.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of crack resisting coating for exterior wall is mainly made by the following weight parts proportion raw material:
White cement 60-100 part, white quartz sand 50-100 part, dispersibility rubber powder 1-4 part,
Vltra tears 0.1-1 part, water reducer 0.5-3 part.
Each proportioning raw materials of above-mentioned crack resisting coating for exterior wall is preferably:
White cement 80-100 part, white quartz sand 50-70 part, dispersibility rubber powder 2-4 part,
Vltra tears 0.5-1 part, water reducer 1-3 part.
According to needs to the wall face different color, can also add an amount of pigment of all kinds in the above-mentioned crack resisting coating for exterior wall (as pigment such as yellow, green, blue, red, orange, its add-on is decided according to the shade needs), to obtain the exterior coating of different colours; Do not add the prepared coating of pigment and be white.
Above-mentioned crack resisting coating for exterior wall can prepare by the method that comprises the steps:
(1), the white cement with described weight part proportioning, dispersibility rubber powder, Vltra tears, water reducer drop in the ball mill, ground 2-6 hour;
(2), then add white quartz sand, ground 0.5-2 hour again, the discharging pack gets final product.
The above-mentioned prepared crack resisting coating of pigment that do not add is white; When needing the crack resisting coating of preparation different colours, the pigment that can add an amount of required color in preparation method's (1) step grinds together and gets final product.
In the preparation process of above-mentioned crack resisting coating for exterior wall, when using ball mill to grind, the rotating speed of ball mill is advisable with 2000-6000 rev/min.
When crack resisting coating for exterior wall of the present invention is used for decoration of exterior wall, gets and to use after aequum coating adds suitable quantity of water mediation evenly, can directly be applied in the sand-cement slurry laminar surface of wall face.
Compared with prior art, the invention has the beneficial effects as follows:
The contriver filters out crack resisting coating for exterior wall of the present invention by further investigation, test of many times for many years, is used for decoration of exterior wall, and is durable in use, be not prone to fade, come off, phenomenons such as be full of cracks and infiltration; And can be at the direct coating of sand-cement slurry laminar surface of exterior wall and difficult drop-off and be full of cracks, do not need between cement sand bed and dope layer, to smear putty layer, making exterior coating technology is two procedures by traditional three process saving, shortens construction period, reduces building cost.
