Description
Technical field
But the present invention relates to a kind of inorganic waterproof coating of wet trade, the especially a kind of skin-type waterproof coating that can combine closely with the concrete basal plane.The invention still further relates to the constructional method of this skin-type waterproof coating in the middle of the waterproof construction engineering.
Background technology
Existing waterproof roll adopts the rubber-like waterproof roll more; Like waterproof rolls such as high molecular weight epdm, blend class waterproof roll and resene waterproof roll, modifying asphalt class waterproof roll, polyethylene polypropylene polymer membranes, and waterproof paint adopts polyurethane water-proof paint more.
Above material is organic materials, and other water-proof material all can not wet trade except that the polyethylene polypropylene polymer membranes, and the waterproof construction basal plane is all had strict requirement: require formation level solid, smooth, clean, dry.In use, need at first blade coating cement mortar screeding layer in reinforced concrete basic unit.Principles of Chemical Engineering according to " dissimilar person is incompatible "; The organic waterproof material can't firmly cohere with the inorganic silicic acid salt material of building body; Especially formation level is dry inadequately when waterproof construction, under the moisture effect, will form " two skins ", causes the generation of " interlayer string water " phenomenon.In a single day the meaning of " two skins " and " interlayer string water " phenomenon pass waterproof layer by water, and just string is moving everywhere, at first from recently the most smoothly passage circulate down, form seepage.When keeping in repair such seepage, leak source and old complaint be not but at same position, and a leak source is repaired and finished; New leak source occurs again at once; Thus, no matter be that what reason causes seepage just to declare the failure of whole waterproofing work, become the buildings waterproof industry and need a big problem of facing badly.
In order to overcome the deficiency of organic waterproof material, people have developed multiple inorganic waterproof material in succession.
The early 1980s, Chinese mechanical industry Import and Export Corporation has introduced the great scientific payoffs product of switching from manufacturing military products to goods for civilian use after World War II from the U.S.---efficient inorganic waterproof paint " when guaranteeing ".The physicochemical property that it the is superior and support of wet trade caused domestic construction waterproof industry scientific and technical personnel's very big concern orders about down the dual of vast market prospect and high added value, and how tame scientific research institutions launch the production domesticization research of " when guaranteeing " one after another.Late nineteen eighties; " waterproof is precious " of " the gram seepage " of " efficient inorganic waterproof paint " in Guangzhou, Building Material Industry Design Research Inst., Shijiazhuang, Beijing National Research Institute of Building Materials Industry becomes big efficient inorganic waterproof paint China's 1980s three successively through technical evaluation.Efficient inorganic waterproof paint after the production domesticization follows U.S.'s " when guaranteeing " and still uses white portland cement to be carrier, yet white cement is a main application with " decoration ", ultimate compression strength is low and the early strength slower development.Therefore,, just need the loaded down with trivial details unkind coating maintaining process of a cover, had a strong impact on applying of efficient inorganic waterproof paint thus in order to guarantee the water resistance of coating.
Summary of the invention
