Abstract

Effects of material factors such as metals, rubbers, fillers, curing agents, accelerators, and others on the fixing strength has been investigated in order to obtain some informations for the fixing mechanisms and the fixing-preventing method. The kind of metals had an effect on the initial fixing strength (FS0) which has a tendency to increase with the hardness of metals. FS0 was influenced by the polarity of rubbers but the fixing strength after 2 days (FS) has a little influence on the polarity. The effect of fillers such as carbon blacks and white carbon on FS is similar to that of fillers on the curing, and carbon blacks generally give the vulcanizates to accelerate the fixing but white carbons give the vulcanzates to depress it. The curing agents such as sulfur and peroxides had a great effect on FS in the kind and amount. FS increased when those give a component which reacts with metals, to vulcanizates. Accelerators which give polysulfide crosslinkages and side chains to vulcanizates, or which give curing residures such as amines and mercaptobenzothiazole to vulcanizates lead to the high fixing stength.
