105-11-3 1,4-Benzoquinone Dioxime C6H6N2O2

1,4-Benzoquinone dioxime is used as a vulcanizing agent for butyl rubber, natural rubber, styrene-butadiene rubber, and polysulfide "ST" rubber, especially for butyl rubber. Oxidants (such as Pb3O4, PbO2) have an activation effect on it. This product is easy to disperse in the rubber material, vulcanizes quickly, and has high elongation strength of the vulcanized rubber.

The critical temperature is relatively low and there is a tendency to scorch. Adding certain anti-scorch agents (such as phthalic anhydride, anti-scorch agent NA) and accelerators (such as thiurams, thiazoles, dithiocarbamates) can effectively improve operational safety.

This product has discoloration and staining properties and is only suitable for dark-colored products. When the accelerator DM is used as the active agent, the scorch resistance is better than that of lead oxide, and the discoloration is also weakened, except for carbon black rubber. When tetrachlorobenzoquinone is used as the active agent, the activation effect is much stronger than that of lead oxide.

This product is mainly used to make air bags, water tires, insulation layers of wires and cables, heat-resistant washers, etc.

Dosage: 1~2 servings. Combined with 10~6 parts of lead oxide or 4~2 parts of accelerator DM.

This product can also be used in self-vulcanizing adhesives and is also a reagent for detecting nickel.
