YN polymer asphalt bridge deck waterproofing coating

I. Introduction YN polymer asphalt bridge deck waterproofing coating with high doses of polymer-based composite material, with a small amount of high-quality asphalt, the fine production into a new composite waterproof coating. The coating not only has excellent elastoplastic polymers, heat resistance and adhesion, but also has a good affinity asphalt products. To accommodate the construction of asphalt concrete at high temperature conditions, become various types of bridges and viaducts surface coatings for waterproofing construction. Second, the main features of a cold construction: As the product is a one-component water-based paint, the use of no heating, no harmful volatile gases, harmful to humans, no environmental pollution, are environmentally friendly products. 2. The construction is simple, easy repair, low viscosity and can be sprayed can also be painted; construction speed, low labor intensity. When asphalt concrete paving, in case of damage to the waterproof layer, as long as the damage to the office, repaint it again. 3. Material performance, after the film elongation, good crack resistance, high temperature is not flowing, low temperature embrittlement, good resistance to temperature changes. 4. Increase the asphalt concrete pavement and adhesive strength and shear strength of cement concrete bridge deck, extending the service life of asphalt concrete. Third, the technical indicators of performance standards: JT / T 535-2004Ⅰ type Item Indicators 1. Appearance Brown homogeneous liquid is stirred, the stirring rod does not adhere to the significant grain 2. Solid content,% ≥ 50 3. extensibility, mm ≥ 5.5 (no treatment) 4. flexibility (-15 ± 2) ℃ no crack, fracture 5. Heat resistance (140 ± 2) ℃ not flowing and sliding 6. cohesiveness, MPa≥ 0.4 7. impermeability, 0.3 Mpa, 30min impervious Fourth, the scope for urban elevated road, overpass, bridge deck waterproofing overpass and highway bridges. Also applied to roads, municipal traffic engineering facilities, for example: box box pipe section, the outer waterproof underground buildings. Five, not construction Note 1. rain or expected rain within six hours after construction, the bridge has hydrocephalus. Temperature less than 5 ℃, not construction between 11:00 to 15:00 the hot season. 2. Before the waterproof layer is not dried, the Master shall walk and moving vehicles, in order to conserve 48 hours after paving asphalt concrete better. 3. prohibited in good waterproofing spray spraying sticky layer of oil on top of another. 4. When the asphalt paving material wheel load should be kept clean, moist, slow-moving vehicles should prohibited brakes or within a bridge support about 5 meters in situ U-turn. 5. waterproof layer if damaged, should be repaired. Six Construction Guide 1. Before final setting of concrete bridge decks, were roughed respond board. 2. When the deck concrete strength of more than 70% moisture content of not more than 15%, the surface no water, can be waterproof layer construction. 3. Deck should be smooth, rough surface, clean, not a concrete mortar, garbage, oil, steel and other can not have sharp protrusions. Before spraying waterproof layer, high pressure blowing dust blowing dust machine clean. 4. Waterproof paint before use, should stir the paint. 5. Waterproof paint spraying should be followed in order uniformly spraying, may not have exposed bottom drain coating, spraying two generally appropriate. Seven, packaging plastic barrels: 50kg / barrel drum: 200kg / barrel Eight, storage and environmental protection 1. Prevent sun exposure spill. Do not close to a heat source, non-freezing. 2. The reservoir above 0 ℃ warehouse, storage period of 6 months, 3. After construction, waste sent to the sanitation department centrally.
