Anthraquinone accelerators are currently the most widely used alkaline accelerators. This class is a medium speed accelerator for natural rubber and synthetic rubber.
When the oxime accelerator is used alone, the sulphurization starts later, the operation safety is high, and the storage stability of the rubber mixture is good, but the sulphurization speed is fast.
Slow (twice slower than the sulfenamide accelerator). The most important feature of the veneer accelerator vulcanizate is the high degree of vulcanization.
High hardness and high tensile stress. However, due to the presence of a large number of polysulfide bonds and more cyclized compounds in the vulcanizate, the heat resistance of the vulcanizate
Poor aging, easy cracking, and large compression deformation. In addition, such accelerators have discoloration and pollution, and are not suitable for white or light.
