Abstract
The invention relates to a waterproof material. The waterproof material comprises the following components: 50-70% of clay or an artificial synthetic material, 1-10% of a clay additive and 20-40% of a silicate mineral matter, wherein the clay additive comprises 50-60% of calcium chloride, 10-20% of a polyacrylamide and 10-30% of aluminum potassium sulfate. The waterproof material of the invention, which not only reserves the plasticity, the dilatability and the waterproofness of clay but also has the compressive strength and the solidification performance of a silicate building material, can be widely applied to underground waterproof engineering and roofing waterproof engineering.
Description
Technical field
The present invention relates to a kind of water-proof material, specially refer to a kind of have high water-repellancy, high barrier property, fire prevention, anti-high temperature, be used for a kind of Powdered inorganic waterproof material of waterproofing work.
Background technology
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 has and water-proof material hardens, decomposes because of the temperature variation of placing environment or other factors cause water-proof function to reduce.In addition, this kind has and water-proof material does not have fire line.
In existing water-proof material, also have with cement class, smectites as water-proof material.Utilize wilkinite water-swelling property 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 patented claim (notification number: the CN 1070826C patent No.: 95120237.5), introduced with clay and the synthetic plasticity water-proof material of MO.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 there is the low defective of ultimate compression strength.
Summary of the invention
The object of the present invention is to provide a kind of permanent stability that have, fire line, ultimate compression strength is high, and manufacturing and construction are simple and cost is low, are applicable to pulverous rigidity clay inorganic waterproof material of large-area construction.The plasticity-, swelling property, the water-repellancy that had both kept clay; The pressure resistance and the solidifiability that have silicate building material again; Realized again that simultaneously other water-proof materials receive the constraint of field condition at underground waterproof, roof waterproof receives the restriction that fire department requires measures for the prevention of fire.
Purpose the present invention to above invention adopts clay 50%-70%, clay additive 1%-10%, silicate mineral 20%-40%; Calcium chloride 50%-60%, SEPIGEL 305 10%-20%, potassium aluminium sulfate 10%-30% in the said clay additive.
Said clay comprises smectite, illite and kaolinite.
Said silicate mineral comprises Portland clinker and silicate cement.
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 water and can be combined by 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 under the carrying of water effect, forming of the clay in the water-proof material of the present invention specifically is the na-montmorillonite of staple, and the interstitial water of laminate structure and oxyhydroxide molecule can get into.This significant water absorbing properties makes sodium ion have the swelling property of height just, in limited space, forms a kind of waterproof membrane of densification, 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 white lake.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, being set in na-montmorillonite waterproof bunch group firmly in the middle of the silicate skeleton 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 received 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 accomplished, 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.
