The Function Of Rubber Vulcanization Accelerator
Before people do not realize the organic accelerator, rubber vulcanization accelerator is mainly used alone sulfur or a sulfur and inorganic accelerator. However, this process requires a lot of sulfur, and high curing temperature, as well as quite a long curing time, and the considerable risk of excessive sulfur. Once excessive sulfur, the mechanical properties of vulcanized rubber will deteriorate, blooming, darkening and aging resistance will be greatly decreased.
To eliminate the above shortcomings, the use of rubber accelerator can be a good solution, the main effect is manifested in:
1. Curing time will be greatly reduced, and the amount of sulfur will be reduced and the curing temperature is reduced.
2. The physical properties of the vulcanizates were improved, such as to improve the strength of elongation, tensile strength, hardness and abrasion resistance.
3 Improving the aging resistance of vulcanizates, preventing blooming, and expand the scope of the vulcanizates.
4 Thick-walled products the vulcanization become possible, the storage stability of the rubber also is improved.
5 Rubber vulcanization accelerator can be made transparent and various shades of rubber products, and applies to a variety of synthetic rubber vulcanization.
