Polymer modification asphalt Waterproof roll , high polymer modified asphalt waterproof sheet: powder, granular, flaky or thin Membrane material The cover material is made into a curly sheet material. The thickness is generally 3mm, 4mm and 5mm, with asphalt base as the main body.
Product characteristics
1. Tensile properties
Comparing the two-layer lamination of commonly used asphalt coiled materials with the single-layer modified asphalt coiled materials, the elongation and tear strength of the modified coiled materials have been greatly improved (see Table 2), and the tensile strength needs further modification. With the decrease of temperature, the performance of the modified asphalt coiled materials is basically not affected, while the elongation of the asphalt coiled materials is significantly reduced, showing the determination of low-temperature brittleness.
2. Adaptability to base cracking In case of base cracking and temperature drop, the adaptability of modified asphalt coiled material is much better (see Table 3)
3. Low temperature flexibility
Ordinary asphalt felt is unqualified below 5 ℃ in low temperature flexibility, but after APP or SBS The modified asphalt coiled material has a particularly obvious effect on low temperature flexibility. (See Table 4)
4. Artificial aging performance
The aging contrast test (determination of softening point) of three kinds of base materials was carried out with a sunlight type artificial aging tester. The asphalt began to harden after 1000 h aging, and then it was completely aged and brittle after 2000 h. The APP modified asphalt had very little change. After 2000 h testing, there was basically no obvious change, and the original softening point was basically maintained. The SBS modified asphalt was in between.
In conclusion, it is simple, practical and effective to blend and modify asphalt with polymer from a macro perspective. In order to improve the performance of asphalt and expand its application range, all countries in the world are systematically studying asphalt chemistry, and asphalt modification is one of the key points of research. Many domestic colleges and universities, research units are also working in this area, and have achieved many results. It is believed that the polymer modified asphalt can be used in the waterproof material industry and other The application of asphalt will get new development.
