Waterproof coating technology of asbestos water dispersed asphalt
The following introduces a kind of architectural coating, which is used as a roof waterproof coating. The formula process is as follows:
1. Asbestos water-dispersed asphalt waterproof coating formula
component name | Specifications | parts by mass |
water | tap water | 500 |
road asphalt | No. 10 asphalt | 180 |
liquid asphalt | 190 | |
asbestos powder | 7 and asbestos linters | 130 |
total | 1002.5 |
2. Production process of asbestos water-dispersed asphalt waterproof coating
Heat the asphalt to 150-170°C to melt and dehydrate until no bubbles are produced, and set aside; heat the water to above 70°C, disperse the asbestos powder evenly with 60% hot water at high speed, and slowly add the boiled asphalt to the In the high-speed disperser, then add the remaining 40% hot water into the disperser in batches until the dispersion is uniform.
3. Main performance
Solid content/% | 60.5 |
Yan Jibi | 1.8 |
Consistency (Disc Consistency Meter)/cm | 8~9 |
Coating toughness (bending diameter 10cm) | no cracking |
4. Purpose
It belongs to thick paint, mainly used as roof waterproof coating and architectural coating.
