Rubber accelerators typically contain a variety of chemical substances that catalyze the vulcanization process, increasing the speed and degree of crosslinking. Common rubber accelerator components include:
Aldehyde-amine accelerators: such as diethyldithiocarbamates, commonly used as primary accelerators, effectively improving the speed and efficiency of rubber vulcanization.
Guarantee accelerators: such as diphenylguanidine, primarily playing an auxiliary role in rubber vulcanization. When used in combination with aldehyde-amine accelerators, they can optimize the vulcanization effect.
Thiuram accelerators: These are multifunctional rubber accelerators, used both as primary and auxiliary accelerators. Their characteristic is the ability to initiate the vulcanization reaction at relatively low temperatures.
Xanthate accelerators: These accelerators play a major catalytic role in vulcanization, significantly increasing the vulcanization speed.
Sulphamide accelerators: Primarily used for post-curing vulcanization, resulting in a flat vulcanization curve, stable focal points, and strong resistance to scorching.
These components can be flexibly proportioned in different applications and under different vulcanization conditions to achieve the best vulcanization effect.
