Abstract
The waterproof material for roofing consists of coal tar, talcum powder, bentonite and polvyinyl acetate emulsion adhesive. It is applied to the crack in roofing to reach leak preventing effect. It has good waterproof effect lasting for 8-10 years. It may be also used in basement, water basin, air defence engineering, underground, tunnel, etc.
Description
(1), technical field
The present invention relates to the chemical composition that the outer waterproofing and leakage-stopping of a kind of buildings is used, specifically a kind of waterproof material for use in outside roofing.
(2), background technology
At China's leakage of buildings is the knotty problem of puzzlement construction industry always.The Highrise buildings wall is many in recent years, and its vault is emphasis waterproof position, also needs very high waterproof ability as subway, tunnel, mine, civil air defense constructions and installations, underground pedestrian walk, water ground etc. in addition.But concrete is the non-homogeneity material, and there are many holes inside, and cement is the meeting shrinkage strain in process of setting, and the evaporation of excessive moisture can stay hole to inside concrete again, so normal concrete is relatively poor from anti-permeability performance.Buildings antiseep one is to add auxiliary agents such as swelling agent, water-resisting agent to improve from water resistance in concrete, the 2nd, realize outer waterproof by adding waterproof layer or patching materials.Outer waterproof is used pitch and tar felt the earliest, the in recent years use by modifying asphalt and non-woven fabrics waterproof roll, as disclosed this type of waterproof roll that all belongs to of CN1052713A, CN1037939A, CN1181435A, JP63-125762, JP61-28571 or the like as the tire material more.
(3), summary of the invention
The application is conceived to the part, promptly shutoff is carried out in the slit of seepage, and its technical scheme is that four kinds of raw materials getting following mass percent constitute composition:
Coal tar 35-45%
Talcum powder 255%
Bentonite 15～25%
White glue with vinyl 5～15%.The preferred proportioning of each component is:
Coal tar 40%
Talcum powder 30%
Bentonite 20%
White glue with vinyl 10%.
To promptly be water-proof material after above-mentioned four kinds of raw material mixing and stirring.This product detects all values of being above standard through Anhui Province's building coating water-proof material quality monitoring testing station to every index, the results are shown in following table:
| Interventions Requested | Unit | Standard value | Assay | |||
| ????1 | ????2 | ????3 | On average | |||
| Sag (80 ℃) | mm | Be not more than 4 | ??1.0 | ??1.0 | ??1.0 | ?1.0 |

| Evaporation rate | ％ | Be not more than 3 | ?1.5 | ?1.3 | ?1.5 | ?1.4 |
| Following blank | ||||||
This product handling ease, with low cost as long as building, both sides, slit (wall) face is cleaned up, is coated with along the slit and spreads water-proof material and get final product.Water-proof material can slowly infiltrate in the slit, and sticks on the wall of slit with flexible state all the time, can be not firm, become fragile and peel off, and identical non-setting adhesive, so good water-proof effect, once constructing reaches 8～10 years action time.This product is not only applicable to the outer waterproof of roofing, is fit to outer waterproof such as vault, pond, fire-fighting pond, civil air defense constructions and installations, water pipe, subway, tunnel, mine, water channel simultaneously.
(4), embodiment
With processing double centner water-proof material is example, and non-limiting examples is described below:
1, gets 35 kilograms in coal tar, 35 kilograms of talcum powder, 25 kilograms of bentonites, 5 kilograms of white glue with vinyl, mixing and stirring.
2, get 45 kilograms in coal tar, 25 kilograms of talcum powder, 20 kilograms of bentonites, 10 kilograms of white glue with vinyl, mixing and stirring.
3, get 40 kilograms in coal tar, 30 kilograms of talcum powder, 20 kilograms of bentonites, 10 kilograms of white glue with vinyl, mixing and stirring.
4, get 35 kilograms in coal tar, 35 kilograms of talcum powder, 15 kilograms of bentonites, 15 kilograms of white glue with vinyl, mixing and stirring.
Claims (2)
