Silica Modified by Using Alcohol Polyoxyethylene
نویسندگان
چکیده
Nowadays, the study of preparing silica/rubber composites, which can be used in “green 16 tire”, in energy saving method is fast-growing. In our work, silica modified by using alcohol 17 polyoxyethylene ether (AEO) and 3-Mercaptopropyltriethoxysilane (K-MEPTS) together were 18 investigated. Thermal gravimetric analyzer (TGA) result indicated that both AEO and K-MEPTS 19 could be grafted on the silica surface. Raman spectroscopy confirmed that the AEO could generate 20 a certain steric hindrance for the mercaptopropyl group on K-MEPTS. Silica modified by using AEO 21 and K-MEPTS together can be completely co-coagulated with the rubber in preparing silica/natural 22 rubber (NR) composites by latex compounding method. AEO can form a physical interface between 23 silica and rubber; meanwhile, K-MEPTS can form a chemical interface between silica and rubber. 24 The effects of chemical and physical interface between silica and rubber on dynamic and mechanical 25 performances of silica/NR composites were also given in this research. A proper combination of 26 physical and chemical interface between silica and NR can improve performances of silica/NR 27 composites. 28

In the current study, amorphous silica nanoparticles were easily extracted from rice husk ash. The target composite was synthesized by the direct incorporation of chloropropyl groups through the condensation of nanosilica and 3-chloropropyl trimethoxysilane and then grafting of 1,3,5-triazine-2,4,6-triamine (Melamine) onto the propyl groups by the simple nucleophilic substitution reaction (RHA@...
