Uncured rubber asphalt Waterproof coating It is made of high quality Petroleum asphalt Functional polymer modifier and special additives are scientifically optimized. This product has a strong creep property, which brings outstanding application characteristics such as self improvement, leakage prevention, channeling prevention, fatigue relief, aging resistance, stress free, etc.
Non curing rubber asphalt waterproof coating , a new type of advanced waterproof coating, subverts the concept of the traditional waterproof field, maintains a viscous gum state for a long time, has strong tensile force, and can relieve fatigue Waterproof roll Composite use, flexible and diverse construction methods, such as scraping and spraying can be used. The barrier free construction can be carried out under high temperature and low temperature.
Product features:
1. Very high solid content
The solid content reaches 99.9%. It is neither a solvent based coating nor an emulsion waterproof coating. It is a finished coating without film forming.
2. Long term non curing
After the construction of the product, it always keeps the state of elastoplastic gel. In the whole service life, the performance remains unchanged for a long time without aging.
3. Self healing of advantages
It can repair the damage caused by external force.
4. Strong creep
It can be used in combination with coiled material to achieve the effect of empty paving even if it is fully sticky
5. High and low temperature construction is barrier free
It is suitable for high temperature and low temperature construction, and can be constructed from minus 20 ℃ to minus 40 ℃.
6. Excellent anti channeling performance
It is fully adhered to the base layer microcosmically, plugging pores and tiny cracks, and realizing true exterior waterproof.
7. Excellent bonding performance
Good adhesion with almost any material. Even in the wet base layer without water, the bonding ability is not affected.
8. Good weather resistance
It will not solidify after long-term contact with air, and its performance will not change.
9. Diversified construction methods
The same material can be sprayed, scraped and grouted with good bonding.
10. Resistance to cracking
It shall not be affected by cracking caused by external forces such as base deformation and settlement.
construction technology
Base construction conditions
The obvious concave and convex unevenness of the base surface should be leveled with cement mortar first; Pipes, embedded parts, equipment foundations, etc. passing through the waterproof layer shall be buried and installed before the construction of the waterproof layer. The gap between the pipeline and the structure shall be tightly sealed with fine aggregate concrete or polymer waterproof mortar. The waterproof base course shall be clean, flat, solid and free from sanding. The drainage slope meets the design requirements. The base course can be constructed wet, but there shall be no open water.
Detail additional layer construction
The water outlet of the roof, the root of the pipe out of the roof, the internal and external corners of the parapet, the gutter and other places shall be coated with 1mm thick non curing rubber asphalt waterproof coating to strengthen the treatment; The construction joints, deformation joints, post cast strips, wall pipes, temporary protective walls, pits, internal and external corners of pools and other places of underground waterproofing shall be coated with 1mm thick non curing rubber asphalt waterproof coating to strengthen treatment.
Coating construction
The coating can be divided into scraping method and spraying method. The construction method can be selected according to the situation and requirements of the construction site. (1) Scraping method construction: it is mainly applicable to the basement baseplate, vertical wall, roof and other parts that are convenient for scraping, node parts and small area waterproof works. The non curing rubber asphalt waterproof coating can be applied after heating, and the thickness of the coating shall be determined according to the design requirements. (2) Spraying construction: it is mainly applicable to large area waterproof construction and concealed tunnel vault and other parts that are not convenient for coating construction.
a、 The spraying operation shall be carried out in sections and covered in advance. The width of each operation shall be 300mm larger than the width of coiled material. Adjust the distance and angle between the nozzle and the base surface as well as the pressure of the spraying equipment to make the surface of the sprayed material flat and uniform in thickness. b、 During construction, the spraying shall be carried out for several times according to the design thickness, and the spraying direction shall be changed alternately during each spraying. The overlapping width of the same layer of film shall be 30-50mm.
The coiled material shall be randomly paved on the surface of the waterproof coating that has been completed. The coiled material shall be paved in a straight, flat and wrinkle free manner. The lap width between coiled materials shall meet the specification requirements. The lap joint shall be cold bonded. The non curing rubber asphalt waterproof coating shall be scraped and applied within the lap joint width of coiled materials. The coiled materials at the lap joint can be constructed directly without surface drying time and rolled with pressure rollers.
Impoundment test
After the completion of the waterproof layer, the roof shall be subject to water storage test as required. It is qualified if there is no leakage after 24h of water storage or 2h of water spraying.
Construction of protective layer
The construction of protective layer can be carried out after the roof waterproof layer passes the quality acceptance. Make corresponding concrete, block material or cement mortar protective layer according to design requirements
matters needing attention
The construction environment temperature should be - 10~35 ℃. Waterproof construction is not suitable in rainy days, snowy days, and above level 5 wind.
The internal and external corners, the corners between the plane and the facade should be plastered into an arc, and the arc radius should be 50mm;
Construction personnel entering the site shall be equipped with corresponding safety protection;
Fireworks are strictly prohibited at the construction site, and good ventilation is maintained
