The first generation：
[1839-1904] the rubber additive products in these years are represented by inorganic vulcanization accelerator. The rubber industry has entered the era of inorganic vulcanization accelerator, but it also has problems such as low efficiency and poor vulcanization performance.
In1839，Discovery of vulcanization system
In1844，The inorganic vulcanization accelerator lead sub-carbonate was found
In1846，Discovery of foaming agent and chloride-sulfur cold cure method
In1904，Carbon black was found to be used in rubber
The second generation：
[1906-1980] the rubber additives in these years were represented by organic vulcanization accelerators, which were vulcanized by aniline. Oenslagar, a German chemist working in the United States, accidentally discovered them in an experiment in 1906.
1906-1908，discovery of organic vulcanization accelerator, thiourea accelerator aniline and CA
In1912，discovery of dithiocarbamate vulcanization accelerator
In1914，discovery of antioxidant
In1915，discovery of zinc alkyl xanthate accelerator
In1920，invention of accelerator M，invention of thiuram accelerators
In1922，invention of guanidine accelerator DPG
In1924，invention of antioxidant AH
In1928，invention of antioxidant A
In1931，invention of sulfonamide accelerator DIBS、CBS、NOBS
1930-1935，antioxidant hydroquinone naphthol, p - phenylenediamine came out
In 1937，Invention of p-phenylenediamine antioxidant
In1940，invention of silane coupling agent
In1943， invention of isocyanate adhesive
In 1960，invention of processing rubber
In 1966，invention of Cohedur
In1969，invention of antiscorching agent
In1970，Invention of triazine accelerator
In1980，invention of Manobond cobalt salt adhesive accelerator
The third generation：
1980 to present：during this period，the main characteristics of rubbers are environmental protection and multifunction
1980-1981，development of the rubber accelerator NS
In 1985，launch of the environment-friendly accelerator MTT
1991 to present，development and application of environment-friendly nitrosamine-free auxiliaries such as thiuram, sulfonamide, zinc salt accelerator, vulcanizing agent and antiscorching agent. The invention in succession of ZBPD、TBSI、CBBS、TBzTD、TIBTD、ZDIBC、OTTOS、ZBEC、AS100 etc
