Modified asphalt stabilizer Industrial additive

Modified asphalt stabilizer

I. Overview:

This range of highly efficient modified asphalt stabilizers is produced using a synthetic and compounding process. The reaction mechanism is: the stabilizer produces an active free group under certain thermal conditions, and cross-links and grafts with the molecular chain of the SBS polymer and the active functional group of asphalt, so that the polymer and the asphalt form a stable colloidal system, thereby improving the thermal stability of the modified asphalt, solving the problem of storage and segregation of the modified asphalt, and making the storage stability of the modified asphalt products reach more than 60 days. After the addition of the stabilizer, a stable phase interface adsorption layer is formed between the polymer phase and the basic asphalt phase in the modified asphalt, which reduces the surface tension of the phase interface and increases the affinity between the two phases; the number of SBS added and used can be reduced, and the comprehensive index of modified asphalt can be improved. The amount of product addition is only half of the original similar products, and the cost performance is excellent.

How to add

Simultaneously with the polymer is added to the matrix asphalt, ground for 15-20 minutes, can also be added to the finished asphalt development tank stirred and dispersed. Recommendation: Test to determine conditions for differences in the reactivity of different polymer/matrix asphalt systems

After SBS grinding twice (confirm that it has been ground) is added evenly, it can also be added to the finished asphalt development tank to stir and disperse. Recommendation: Test to determine conditions for differences in the reactivity of different polymer/matrix asphalt systems

Scope of application

It is used in the production of polymer modified asphalt, especially for SBS thermoplastic elastomers, styrene-butadiene rubber modified asphalt, and can also be used for rubber powder modified asphalt and high viscoelastic modified asphalt. The reaction process has small heat release, no volatiles, insoluble in water, stable at room temperature, non-toxic and odorless, and safe to operate.

stockpile

Storage is kept at room temperature, dry, isolated from strong acids, strong alkalis, and heat sources to prevent moisture.
