PB type polymer asphalt Waterproof coating
1、 Product Overview
PB type polymer asphalt waterproof coating It is a polymer modified asphalt waterproof coating prepared by compounding various rubbers to modify asphalt. PB type polymer asphalt waterproof coating is harmless, tasteless, free of environmental pollution, and cold construction; The main advantage of PB waterproof coating is that the rubber in the modified asphalt forms a continuous network and penetrates each other, cross-linking, so that the modified asphalt presents a polymer performance; PB-1 waterproof coating keeps rubber elasticity and low temperature flexibility after the film is dry; PB waterproof coating has strong shear resistance and can withstand the long-term load of the bridge deck, which can prevent structural damage caused by water seepage and delay the service life of highway bridges. PB-1 waterproof coating is used for bridge deck relatively It is an ideal waterproof material, and can also be used for waterproof, anti-seepage, anti-corrosion wall Waterproof and leakproof. PB waterproof coating not only has good waterproof performance, but also can absorb the stress and noise of road and bridge deck as the stress absorption layer; Because PB-1 waterproof coating has certain elastic and plastic deformation capacity, it can bear the load without being damaged. Alleviate the aging of road and bridge pavement and delay the service life.
2、 Construction process
Clean the base course - Treatment of key points - the first Waterproof layer - The second waterproof layer - The third waterproof layer (multiple spraying can be carried out according to the construction requirements) - Waterproof layer maintenance - paving asphalt concrete
3、 Product consumption
PB type polymer asphalt waterproof coating is generally 1.5-3 kg/㎡, and can be adjusted according to the project grade.
4、 Precautions
1. Before construction, brown brush and brush shall be fully soaked to make them soft and smooth.
2. No construction is allowed when the temperature is below 0 ℃ or above 35 ℃ (high-temperature construction shall be avoided).
3. The storage and transportation temperature is 5 ℃ - 35 ℃.
4. The construction shall be carried out in the weather without rain and snow within 4 hours.
5. It is forbidden to step on or drive on the vehicle before the film is dry or asphalt is paved.
6. The construction tools shall be washed with water immediately after use for reuse.
5、 Packaging , retention period
PB type polymer asphalt waterproof coating Generally adopted Packed in 50kg plastic bucket or 200kg iron bucket, the shelf life is 6 months.
