There is a very complex relationship between the modified asphalt chemical composition and structure of chemically modified asphalt and the resin structure, physical function and activity behavior. Modified asphalt can improve the physical properties of asphalt by modifying the internal structure of the asphalt. The following briefly introduces the production mechanism of modified asphalt

The modified asphalt compatibility system has two stability meanings: one is the physical stability of the system, that is, the polymer particles and the asphalt phase do not separate or separate during the heat preservation process; the changes in physical education performance will not follow the passage of time. And change. The compatibility and stability of modified asphalt should be checked by checking the compatibility between the base asphalt and the polymer, and adding appropriate additives.

According to the principle of asphalt modification, the asphalt is mixed with the polymer compatible with the system, and the operating modified asphalt efficiency of the asphalt is measured, regardless of the dispersion and expansion of the polymer in the asphalt, or the dispersion and expansion of the polymer in the asphalt. Constituting the continuous phase, the dispersion and reorganization of the asphalt in the polymer can improve the high temperature and low temperature performance of the asphalt, and better reflect the performance of the polymer. Therefore, the polymer absorbs the oil in the bitumen into a continuous network structure, which plays a key role in the modification of the polymer.

Modified asphalt itself will change, but the asphalt molecules will not change. The chemical modification process is as follows: the full part of the asphalt is easily adsorbed, and the polarity is closer to the colloid after melting. Partial compatibility of bitumen extrusion changes the dispersion of bitumen components and affects the phase transition of bitumen; the basis for modifying polymers and improving bitumen performance is the excellent adsorption of bitumen components on polymer particles. The dissolving and adsorption of polymer particles in the asphalt component is a dynamic process, which has an important influence on the spatial three-dimensional network structure of the modified asphalt polymer, and then affects its function.If you have any other questions, please contact us for modified asphalt details or contact us directly.
