Modified asphalt Daoqiao Waterproof Coating AKD-331E

Product specification

Different composition of composition is divided into PB-I and PB-II type.

product features

1. The coating is non -toxic, solventless, and solid content reaches 65 %. Single components, cold construction, safety and convenience without public harm.

2. The coating has a good adhesion and the cement concrete, and it also has good adhesion to asphalt concrete. The coating has excellent moisture resistance, and it can still be constructed as usual when the water content of the grassroots is <16%.

3. Excellent thermal resistance, with the set asphalt concrete paving temperature, its composition and performance will not change.

4. Under cold climate, it still has good flexibility.

5. The waterproof layer is between the concrete and asphalt concrete. It has a good bonding performance, and the asphalt concrete and cement concrete are bonded into a unified whole. It has high tensile strength and deformation ability, and can withstand the impact and structural deformation of the load.

6. The anti -aging performance of the waterproof layer is good.

Applications

Used for waterproof waterproof, which can prevent reinforced corrosion caused by water seepage of concrete bridges, and improve the service life of the beam body for waterproof, anti -seepage, anti -corrosion, wall waterproof, moisture -proof, moisture -proof, moisture -proof, moisture -proof, moisture -proof, moisture -proof, and moisture. wait.

Construction process

1. Grassroots treatment (blowing dust).

2. Mechanical spray, waterproof coating (spray) of the bridge deck.

3. Mechanical spray again, waterproof coating (spray).

4. Maintenance.

5. Pad asphalt concrete.

Precautions

1. The grassroots should be clean, flat, solid, no sand, powder, fell off, cracks, etc.

2. The coating can be added with non -woven or glass cloth.

3. The coating can be painted or sprayed during construction. In principle, multi -layer paint is used.

4. The coating can be appropriately diluted in the process of painting and painting. When the temperature is high in summer, the construction should be avoided to prevent the construction of the sun, so as to avoid small bubbles caused by the rapid evaporation of the water.

5. The temperature is lower than 5 ° C and rainy days or within 6 hours.
