  • Method of preparing bio-based elastomer composition comprising silica and polydibutyl itaconate-ter-isoprene-ter-glycidyl methacrylate
    Patent number: 10494514
    Abstract: The present disclosure involves a preparation method of bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite. Bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite is environment-friendly, and silica and poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) are derived from non-petroleum base materials, which do not rely on fossil fuel. Compared with nanocomposite without nanocomposite, nanocomposites with glycidyl methacrylate have better silica diffusion, mechanical properties and wet-skid resistance of rubber product are improved while consuming the same time. Further, rolling resistance is decreased so that using silane coupling agent is avoided. Therefore, the processing technology is simplified, and VOC emission is avoided. It is a kind of “green tire” rubber product.
