Jin Hongdun (JHD231) cement Water property of concrete bridge deck epoxy asphalt Waterproof bonding layer standard DB/T2285-2012 is imported modified polymer Elastic emulsion With silicate and other materials as the main raw materials, a variety of auxiliary . One component water-based building waterproof material made of filler through scientific processing and production; It not only has the characteristics of high strength of cement cementitious materials, but also has the advantages of high elasticity and good waterproof performance of polymer film; The product indicators are in line with the standards.
Performance characteristics
1. It has strong impermeability. The water-based epoxy asphalt waterproof bonding layer of cement concrete bridge deck can be used for waterproof construction on the back surface with high water seepage pressure.
2. It is heat resistant, weather resistant, water resistant, alkali resistant, freeze-thaw resistant and has a long service life.
3. Corrosion resistance, carbonization resistance, chloride ion penetration resistance, * * *. It can effectively protect the reinforcement.
4. It has strong bonding ability and has good bonding ability for common building materials such as concrete, masonry, polystyrene board, etc.
Main purpose
1. Underground works, indoor kitchens and toilets, septic tanks and biogas digesters.
2. Reservoir dam, various transmission and drainage pipelines.
3. External thermal insulation wall of the building.
Construction method
1. Mixing: put the powder into the mixing bucket for the water-based epoxy asphalt waterproof bonding layer of cement concrete bridge deck, use the * * * mixer to slowly mix it into a paste without any particles, and add appropriate amount of water as required.
2. Base surface treatment: After the base surface is treated, fully wet it with water (but no water), and then scrape or plaster the prepared slurry on the base surface with a scraper or trowel. After the coating is hardened, it shall be scraped or plastered for the second time along the cross direction, and the thickness of each time shall be 0.50mm - 0.70mm. 48 hour wet curing shall be carried out after one time of scraping.
matters needing attention
1. Construction shall be carried out at a temperature above 5 ℃. It is estimated that the construction is not suitable for rainfall within 24 hours.
2. Theoretical coating amount: 2kg/㎡ - 3.5 kg/㎡
3. Product storage: stored in a cool, dry and ventilated place. The unsealed product of water-based epoxy asphalt waterproof bonding layer on cement concrete bridge deck can be stored for more than 12 months.
