The vulcanization accelerator is called accelerant for short. A substance that promotes vulcanization. The vulcanization time of rubber can be shortened or the vulcanization temperature can be reduced
The dosage of agent and the improvement of physical and mechanical properties of rubber. It can be divided into inorganic accelerators and organic accelerators. In inorganic accelerators, deoxidation
Zinc, magnesium oxide, lead oxide and other small amount of use, the rest mainly used as accelerators. Most are organic. There are many kinds. sulfur
Some of the chemical accelerators are bitter (such as the sulfide accelerator M), some are discoloring (such as the vulcanizing accelerator D), and some are vulcanizing (such as vulcanizing)
Vulcanizing accelerant TT), some have anti-aging or plasticizing effects (such as the vulcanizing accelerant M).
According to the speed of action, can be divided into slow speed, medium speed, medium speed, overspeed, overspeed and other accelerators. In addition, there are also aftereffect accelerators
. They are mainly organic compounds containing nitrogen and sulfur, such as aldehydes (such as H), guanides (such as D) and chulam
(such as TT), thiazole (such as M), dithiocarbamic acid (such as ZDMC), xanthan acid
Salts (such as ZBX), thiourea (such as na-22), sulfonamides (such as CZ), etc. general
Use separately or in combination, depending on the circumstances.
