Description
Technical field
The present invention relates to a kind of waterproof agent for building be made up of organism, belong to the admixture of material of construction.
Background technology
The important component part of construction work during buildings waterproof, in this year, buildings waterproof problem receives the concern of the country and people especially day by day.Exploitation waterproof novel material is a new problem of Building technology personnel.The advantage of water-proof material to improve density and the impermeability of concrete or mortar, and cost is low, does not substantially increase executive cost.Waterproof type water-resisting agent provides effective sealing and no matter is liquid or the moisture of gaseous state, it by substrate surface or near.
Traditional water-proof material such as pitch adds malthoid, exist easily aging, the life-span is short, difficulty of construction is large, high in cost of production shortcoming.But the complex regions such as modified bituminous pitch coiled material, APP, SBS coiled material, BBI mortar water-proof material are not easily constructed, ageing-resistant, water tolerance is bad.
At present, water-resisting agent has become the important application of aqueous polymer modified cement-based material.In numerous water-resisting agent kind, waterproofing agent of organosilicon is extensively promoted in buildings waterproof owing to having excellent hydrophober, antifouling, weathering resistance and endurance quality.It directly can mix in sand-cement slurry or concrete with the aqueous solution or emulsion form and make water-resisting agent, produces Chemical bond, forms firmly integral rigidity waterproof, improve concrete water-repellancy weathering resistance and endurance quality with concrete surface.
The water-based organic silicon waterproof agent of current building field widespread use mainly contains Methyl-CpG binding proteins and the large class of containing hydrogen silicone oil emulsion two, and is mainly used in the surface treatment of base material, is formed directly mix in cement concrete with water-based.The former can make cement concrete rapid hardening too by force at alkalescence, even if still very large on the setting and harden impact of cement concrete with modification in passing through; The latter can produce a large amount of hydrogen and foam in the alkaline environment of cement concrete, can not use.Alkoxyalkyl silicon and modified compound thereof have active reactive group, react, are attached on cement concrete securely, thus greatly improve its water-repellancy and weather resistance under catalyst action with grout or concrete.
Alkoxyalkyl silicon has very large delayed coagulation to sand-cement slurry.The intensity of waterproof mortar is high, and the space of mortar concrete reduces, and space refinement, has more excellent waterproof effect, the problem that gross porosity refinement also makes water-repellancy under higher aliphatic acids water-resisting agent Long term immersion reduce be improved significantly.
Waterproof paint of the present invention is mainly applicable to the anticorrosion of the nontoxic environment such as tap water water factory, is specially adapted to industry and the protection of sewage treatment plants concrete structure, the protection of water pipe, provide protection are lasting.
The invention provides that one is prepared simply, construction technology is easy, cost is low, and ageing-resistant, that waterproof, cohesiveness are good waterproof agent for building.
For a high-effect water-proof agent for construction work, containing organosilicon-modified acrylate 14 ~ 30%, inorganic calcium salt 2 ~ 3%, inorganic molysite or inorganic ferrous salt 2 ~ 3%, inorganic potassium salt 2% ~ 3%, pH value regulate 0.05 ~ 1%, and surplus is water.
