Abstract
The invention provides a waterproof material. The material is mainly used for plastering lightweight sand with blocks, concrete hollow blocks, coal ash blocks, gypsum boards, cast-in-situ concrete, and other base surfaces. The product has good adhesion to a base surface, the construction thickness is very thin, the materials are economic and practical, materials are saved, and at the same time after the base is treated by the material, even if the base is in an environment with large humidity for a long time, phenomena of empty drum and shell do not exist, so that cleaning of the construction site is guaranteed, and environmental protection requirements are met.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of waterproof material.
Background technology
Along with the fast development of building industry, plastering engineering, as a part important in construction, is increasingly paid attention to by this industry.Plaster and can protect body of wall and improve indoor sanitation condition, strengthen light line reflection, beautify the environment, also can protect the erosion of the position not wind-engagings such as wall body, ceiling, roofing, rain, snow, improve metope protection against the tide, efflorescence prevention, heat insulation ability, strengthen the durability of wall body.But the plastering material of traditional handicraft such as cement mortar, mixed mortar etc., it is impossible to the surface adapting to the novel wall material such as building block, sheet material is whitewashed, it may appear that hollowing, ftracture, the phenomenon such as come off, and affects construction quality.In the environment that humidity is bigger, still can there is hollowing, ftracture, the phenomenon such as come off in product in the market, therefore market demand has a kind of cement group water-proofing material, replaces existing technique, to reduce cost, improves work efficiency.
Summary of the invention
It is an object of the invention to provide a kind of waterproof material.This material is a kind of cement group water-proofing material after modified, is mainly used in lightweight sand and adds building block, it is also possible to plaster use in basal planes such as concrete hollow block, fly ash building block, plasterboard and cast-in-place concretes.
The invention provides a kind of waterproof material, be made up of the component of following percentage by weight:
Portland cement 30%-50%
Quartz sand 35%-50%
Ground calcium carbonate 5%-15%
Bentonite 3%-5%
Redispersable latex powder 0.1%-0.3%
Cellulose ether 0.3%-0.5%
Citric acid 0%-0.2%
Calcium formate 0.5-1.0%
Wollastonite powder 0-5%
Carborundum 0.1%-0.5%
Li-montmorillonite 0.02-0.07%
Preferably, described portland cement is 32.5R or 42.5R cement；
Preferably, described quartz sand is 30 order-80 order sand；
Preferably, described bentonite is organobentonite；
Preferably, described redispersable latex powder is the rubber powder that polyvinyl acetate generates through copolyreaction with polyvinyl alcohol；
Preferably, described cellulose ether is methyl hydroxyethylcellulose ether or methylhydroxypropylcellulose ether.
The useful of the present invention is effectively in that: adhere well to power with basal plane, construction thickness is very thin, material is economical and practical, material can be saved, even if the basic unit after this material processes is in for a long time in the environment that humidity is very big and flakes without hollowing simultaneously, can ensure that job site is cleaned, more meet environmental requirement.
Detailed description of the invention
Embodiment 1
A kind of cement group water-proofing material, is made up of the component of following percentage by weight:
42.5R portland cement 40%
Quartz sand 60 order 42%
Ground calcium carbonate 10%
Organobentonite 4%
Redispersable latex powder 0.2%
Methyl hydroxyethylcellulose ether 0.4%
Citric acid 0.12%
Calcium formate 1.0%
Wollastonite powder 2%
Carborundum 0.25%
Li-montmorillonite 0.03%
Described redispersable latex powder is the rubber powder that polyvinyl acetate generates through copolyreaction with polyvinyl alcohol；
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
