摘要：

The sol-gel reaction of tetraethoxysilane was conducted in natural rubber (NR) matrix to obtain NR/in situ silica mixtures. In other words, in situ filling of silica onto NR was conducted. The mixtures were compounded with curing regents, and their viscosities were evaluated. The in situ silica with a coupling agent afforded the lowest viscosity compared not only with a conventional silica (VN-3) but also with a carbon black (HAF). The curing behaviors were most favorable for in situ silica compound. Physical properties of the vulcanizates were also evaluated, and again in situ silica stock gave the best result.
