dc.description.abstractThe feasibility study of utilising amine-treated silica on reinforcement of S~fRL, E~"R 25 and ENR 50 by using semi-efficient (semi-EV) system was carried out. The amine-treated silica was prepared by treating normal silica filler in a butylamine solution with a certain pH. An investigation was carried, out to compare the reinforcement effect of aminetreated silica with that of normal silica with and without the addition of bis (triethoxysilylpropyl)tetrasulphide or TESPT, and with that of carbon black (HAF 330) on cure characteristics and properties of those rubbers. It was found that amine-treated silica gave shorter cure time than normal silica with and without the addition ofTESPT, and closer cure time to carbon black. . It was also found that amine-treated silica showed better tensile strength, mechanical and ageing properties than other fillers, when compounded with SMR-L. On ENRs, amine-treated silica caused better tensile properties, abrasion and ageing resistances than normal silica with and without the addition of TESPT, and a little poorer in those properties than carbon black. Investigation on reinforcing efficiencies of those fillers on the rubbers found that the higher reinforcing efficiency of amine-treated silica is attributed to smaller particlesize and better dispersion of amine-treated silica in the rubbers phases when compared with normal silica with and without TESPT.en_US
