Go Green modified asphalt stabilizer is a high-performance stabilizer developed using American technology. It is widely used in SBS modified asphalt to improve the compatibility of SBS asphalt, effectively prevent the occurrence of segregation, reduce the amount of SBS added, and improve the improvement of SBS asphalt. quality of asphalt. SBS modified asphalt is a system composed of the polymer SBS evenly dispersed in asphalt through physical methods. There is partial adsorption compatibility between SBS and asphalt. The system is a thermodynamically unstable system and is prone to separation of the two phases. , thus causing segregation. Modified asphalt stabilizers improve the thermal stability of modified asphalt by stabilizing the interface between the two phases of the polymer and the asphalt system, thereby solving the segregation problem in the transportation and storage of modified asphalt. In addition, this product can also increase the softening point of the finished asphalt, improve the adhesion with the stone, and increase the peeling resistance.
Functions and characteristics of modified asphalt stabilizer:
1. Promote the dispersion of SBS and basic asphalt and reduce the amount of SBS added.
Adding modified asphalt stabilizer can promote the formation of a stable phase interface adsorption layer between the polymer phase in modified asphalt and the basic asphalt phase, increase the compatibility between the two phases, and promote the dispersion of SBS particles.
Index tests show that indicators such as penetration and softening point have been greatly improved. Microscopic observation: The polymer SBS particles are evenly distributed in the asphalt, and there is no clustering of polymer particles.
Adding modified asphalt stabilizer has low cost and small amount of stabilizer. It has a great price advantage compared with the stabilizers currently on the market. Save 10%-20% of SBS while ensuring the quality of modified asphalt.
2. Improve the thermal storage stability of SBS modified asphalt and prevent segregation from occurring.
Due to the high viscosity and elasticity of SBS, when SBS modified asphalt is stored and transported under static conditions, the tiny particles of SBS that form the dispersed phase tend to agglomerate in the upper part of the asphalt tank, resulting in separation and segregation.
This instability is detrimental to the thermal storage and long-distance transportation of large-scale production of SBS modified asphalt, especially the problem of long-distance transportation and sales is not easy to solve.
Adding modified asphalt stabilizer can improve the thermal storage stability of SBS modified asphalt and prevent segregation.
