Abstract
Methyl vinyl silicon rubber (MVQ) composites were reinforced by adough-moulding compound (DMC), in which silica was used as filler by blending method. The influences of silica and DMC content, and cure conditions on the mechanical and thermal properties of the composites were investigated. The compatibility and crosslinking structure of the composites were examined by SEM and Fourier transform infrared spectroscopy (FTIR) analysis. The results showed that DMC/MVQ composites had very good mechanical and thermal properties when the formula of the compound was MVQ 100, DMC 70 and silica 35 phr, and the cure conditions were 170 °C for 30 min under 10 MPa. The compatibility between DMC and MVQ was good, and C-O-C bonds between unsaturated polyester (UP) and MVQ were revealed by FTIR analysis. The mechanical and thermal properties of DMC/MVQ were obviously improved.
