Abstract
A rigid inorganic waterproofer contains 40-60% bentonite, 40-60% man-made clay, 30-50% silicate mineral matters, 1-10% clay additive. The clay additive comprises: relative to 100 parts by weight of clay additive, 10 -30% polyacrylamide, 5-20% potassium aluminum sulfate, 40-60% calcium magnesium chloride, 5-20% sodium fluosilicate. The inorganic waterproofer has plasticity, expandiblilty and waterproof of clay, at the same time has the antipressure strength and solidifiability of silicate construction material, which could be used in underground waterproof constructions and house waterproof constructions.
Description
The present invention relates to a kind of water-proof material, specially refer to a kind of relevant with clay, wilkinite, silicate minerals, have high water-repellancy, high barrier property, fire prevention, prevent that high temperature, frost heaving resistant have permanent stability, are used for a kind of Powdered inorganic waterproof material of waterproofing work.
In existing various water-proof materials, sealing materials such as pitch system, rubber system, resin system are arranged, these belong to the organic waterproof material, and this kind organic waterproof material hardens, decomposes because of the temperature variation of placing environment or other factors cause water-proof function to reduce.In addition, this kind organic waterproof material does not have fire line.
Use the cement class in addition in existing water-proof material, smectites is as water-proof material.Utilize the wilkinite water-swelling that wilkinite is directly used with the state construction of powder, saccharoid, these water-proof material application properties reach and keep waterproof effect two aspects all can't reach for a long time.
At water-proof material patent application (notification number: the CN 1070826C patent No.: 95120237.5), introduced with clay and the synthetic plasticity water-proof material of mineral oil.Also useful wilkinite and pitch synthetic swelling soil clay product and granulous wilkinite waterproof coiled material material, more than three kinds of water-proof materials in large-area underground waterproof engineering and roof waterproof engineering, all exist complex manufacturing, constructional difficulties is many, production cost is high shortcoming.In addition, also exist ultimate compression strength low.
The object of the present invention is to provide a kind of permanent stability that have, fire line, the ultimate compression strength height is made and construction is simple and cost is low, is suitable for pulverous rigidity clay inorganic waterproof material of large-area construction.The plasticity-, swelling property, the water-repellancy that had both kept clay, the ultimate compression strength and the solidifiability that have silicate building material again, realized again that simultaneously other water-proof materials are subjected to the constraint of field condition at underground waterproof, roof waterproof is subjected to the restriction that fire department requires measures for the prevention of fire.
Purpose the present invention at above invention adopts wilkinite or synthetic clay 40-60%, silicate mineral 30-50%, (clay additive is with regard to the clay additive of 100 weight fraction for clay additive 1-10%, it consists of polyacrylamide 10-30%, aluminum potassium sulfate 5-20%, calcium chloride magnesium 40-60%, Sodium Silicofluoride 5-20%, for this inorganic salts is guaranteed to have enough amounts, its sealing phase double replacement hybrid reaction is got.) can do the waterproof layer filler when constructing at the scene, can add an amount of water again and mix and stir into needed denseness construction surface is constructed, getting final product according to ordinary concrete mortar operation construction.
Water-proof material of the present invention is met the combination of water energy fast hydration, slowly forms the mechanism characteristic that inorganic gel solidifies colony.Its characteristic limitations the extreme swelling property of clay molecules, stoped the water permeability of silicate minerals again.The silicate that is exactly a kind of laminate structure of forming of wilkinite in the water-proof material of the present invention or synthetic clay specifically under the carrying of water effect is the na-montmorillonite of main component, and the interstitial water of laminate structure and oxyhydroxide molecule can enter.This significant water absorbing properties makes sodium base ion have the swelling property of height just, forms a kind of waterproof membrane of densification in limited space, thereby reaches excellent waterproof effect.
Added silicate mineral among the present invention, the wherein calcium hydroxide that in hydration process, produces of Dicalcium Phosphate (Feed Grade), tricalcium silicate and the additive generation chemical reaction among the present invention, and then generate water-fast colloidalmaterial such as aluminium hydroxide.Simultaneously with water in the drated calcium aluminate effect, generate and have certain expansile double salt calcium sulphoaluminate crystal.These colloidalmaterials and crystal are filled in silicate mineral and the na-montmorillonite gel bunch group, thereby have improved their later stage ultimate compression strength and water proof anti-seepage ability.
Additive among the present invention reacts to each other and generates the calcium hydroxide effect that multielement complex compound and silicate mineral aquation are separated out, generate multiple calcium salt, and then generate chlorine Calucium Silicate powder, calcium chloroaluminate and calcium sulphoaluminate crystal, and further improved density, have high water-repellancy.
Na-montmorillonite molecule water-swellable generates waterproof bunch group, rapid solidification after the silicate mineral chance hydrate, meeting water at the na-montmorillonite molecule does not also come and expands when generating waterproof bunch group, strong silicate, calcium chlorate crystalline framework have been formed, na-montmorillonite waterproof bunch group is set in the middle of the silicate skeleton firmly tightly.Make it become the compound population that solidifies with good water resistance and rigidity.Na-montmorillonite powder after moisture is a kind of tough and tensile softening milk, can the sealed silicon hydrochlorate, the crack in the chloric acid calcium salt crystalline framework, can not lose its water-tight performance through aquation circulation frost heave repeatedly, so have permanent stability.
Another characteristics of the present invention, water-proof material was subjected to the constraint requirements scope of operation drying of field condition when the waterproofing work operation in the past, and the present invention does not have this restriction.Anti-water engaging surface is preferably fully moistening, but open fire is not arranged.Water-proof material of the present invention for keeping secular ultimate compression strength, will keep humidity at solidificating period.After freezing period is finished, though because of through the time dry or solidify the be full of cracks that the back that causes constructing produces trace, its reversible expansion compactness of performance that also can absorb water once again, thus with the closely knit round-robin waterproof effect in indefinitely that reaches of micro-crackle expansion.
Can fully find out the characteristics of ultimate compression strength height of the present invention, water-repellancy, barrier properties and permanent stability aspect by the experimental result of table 1.
