Abstract
The rigid water-proof material for flat roof is made of lime hydrate, slags, carbolic acid and sodium carbonate.
Description
The present invention relates to a kind of waterproofing materials, particularly a kind of material of flat roof deck rigid waterproof slag is suitable for various flat roof decks.
Existing flat roof deck rigidity water-proofing material is mainly based on the prestressed reinforced concrete rigid waterproofing, add measures such as smearing waterproofing unction, carry out waterproof, utilize this method to carry out the flat roof deck of rigid waterproofing, its cost height, construction is complicated, prestressed reinforced concrete is subjected to thermaesthesia big in addition, often cause crackle, make it not reach its waterproof effect in advance to spreading upon its surperficial waterproofing unction.Usually the three floors of tarred felt and four floors of tar waterproof method that adopts also has its drawback, when temperature is higher (summer), pitch prill easily trickles, and malthoid easily plays drum, when temperature is low (winter), pitch prill becomes fragile easy to crack, after several freeze thawing, and aged deterioration after the malthoid degreasing, lost water-proof function, cost is high again simultaneously, and the construction at high temperature complex process, and is poisonous, be that contaminated environment is harmful to the person again, energy consumption is bigger.The present waterproof powder that uses, though cost is low, its corrosion-resistant through the several cycles trickle, after waterproof powder is flushed away, is exposed the basis, the very fast disappearance of water resistance.
For solving the defective of above-mentioned waterproofing materials, common way is to adopt the flexible waterproof material waterproof.Chinese patent application (application number: 86105882, denomination of invention: a kind of material of making the ternary butyric rubber waterproofing coiled material) propose a kind of ternary butyric rubber waterproofing coiled material, though it can solve above-mentioned many drawbacks, cost is higher, construction is assorted multiple, for domestic consumer can not adopt.
Task of the present invention provides a kind of material of flat roof deck rigid waterproof slag, and it is not only manufactured simply, and is cheap, and raw material are easy to get the constructing operation convenience.
Task of the present invention is finished as follows: quicklime is cleared up be transformed into hydrated lime, carrying out grinding then, to become fineness be the 0.08mm powder of (being equivalent to more than 120 orders), it is 0.08mm powder (being equivalent to more than 120 orders) that slag also grinding is become fineness, curing compound carbolic acid and soda ash is levigate respectively, fineness is 0.08mm (being equivalent to more than 120 orders), it is stand-by that heating (80 ℃) mixes (mixing ratio is 1: 1) then, above-mentioned four kinds of raw materials are pressed following proportioning (0.5-2) slaked lime: (0.25-1.5) Shanghai slag: (0.025-0.05 carbolic acid: (0.025-0.05) soda ash, even with the forced mixer dry mixing, weighing 50kg pack is stand-by, so just made the material of flat roof deck rigid waterproof slag, material-water ratio is 2: 1 when construction.
The present invention is because of quicklime is cleared up in employing, slag is a primary raw material, so raw material are easy to get, cost is low, and manufacture craft is simple, easy construction, the various indexs of making by said ratio in flat roof deck rigid waterproof slag material construction back (construction thickness 25mm) all meet the architectural design requirement.
(1) intensity R 〉=15Mpa
(2) impervious index 〉=4Mpa
(3) tensile strength 〉=15Mpa
(4) the 1. moving hydraulic pressure 1kg/cm of impermeability
2, do not soak in 10 hours
2. hydrostatic soak 150 days no any permeable
(5) the freeze thawing circulation is 25 times, and product does not have any variation;
(6) alkali resistance: saturated Ca (OH)
2Soak 30 days no changes;
(7) acid resistance: concentration 20% (HCl) solution soaks 30 days no changes:
(8) high-low temperature resistant: 1. in 60 ℃ of thermostatted waters, 30 days no accumulated water phenomenons
2. 300 ℃ of electric furnaces are baked 4 hours no changes
3.-50 30 days no changes of ℃ constant temperature
(9) coefficient of thermal conductivity R=0.15kc/mh ℃
(10) durability: the anti-aging and waterproof time limit was greater than 30 years.
Be described in further detail below in conjunction with embodiment.
Select high-quality quicklime, with the water pouringization commonly used that accounts for lime content 30-45%, the winnowing machine selection by winnowing is passed through in the pouringization back, or screens fineness requirement≤0.08mm (being equivalent to more than 120 orders), screen over-size≤8%, CaO content≤2% with the 0.08mm square hole screen; After the slag drying, levigate with ball mill, by the screening of 0.08mm square hole screen, fineness requirement 0.08mm (being equivalent to more than 120 orders), screen over-size≤8%, loss on ignition≤5%; Curing compound carbolic acid and soda ash is levigate by ball mill, the screening of fineness requirement 0.08mm square hole, screen over-size≤8%, 1: 1 is heated to 80 ℃ of mixing; Above each material is mixed by following match ratio, use the forced mixer dry mixing, mixing the back pack thoroughly can be stand-by, slaked lime: slag: carbolic acid: soda ash=(0.5-2): (0.25-1.5): (0.025-0.05): (0.025-0.05), its optimum formula is a slaked lime: slag: carbolic acid: soda ash=1: 0.5: 0.025: 0.025, as long as being added water, above batch mixing stirs into gel in use with forced mixer, being transported to the job site then carries out floating press polish (thickness is 25mm) and get final product batch mixing: water is 2: 1.Owing to the flat roof deck rigid waterproof slag material construction impervious index 〉=4MPa in back that makes by said ratio, so just reached the purpose of flat roof waterproof.
Claims (3)
1, a kind of material of making the flat roof deck rigid waterproof slag is characterized in that this material is made up of a certain proportion of slaked lime, slag, carbolic acid and soda ash.
2,, it is characterized in that the proportioning between the raw material is (0.5-2) slaked lime: (0.25-1.5) slag: (0.025-0.05) carbolic acid: (0.025-0.05) soda ash by the material of the described flat roof deck rigid waterproof slag of claim 1.
3, by the material of claim 1 or 2 described flat roof deck rigid waterproof slags, it is characterized in that the best proportioning between the raw material is a slaked lime: slag: carbolic acid: soda ash=1: 0.5: 0.025: 0.025.
