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.

 

In1839Discovery of vulcanization system

In1844The inorganic vulcanization accelerator lead sub-carbonate was found

In1846Discovery of foaming agent and chloride-sulfur cold cure method

In1904Carbon 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.

 

1906-1908discovery of organic vulcanization accelerator, thiourea accelerator aniline and CA

In1912discovery of dithiocarbamate vulcanization accelerator

In1914discovery of antioxidant

In1915discovery of zinc alkyl xanthate accelerator

In1920invention of accelerator Minvention of thiuram accelerators

In1922invention of guanidine accelerator DPG

In1924invention of antioxidant AH

In1928invention of antioxidant A

In1931invention of sulfonamide accelerator DIBSCBSNOBS

1930-1935antioxidant  hydroquinone naphthol, p - phenylenediamine came out

In 1937Invention of p-phenylenediamine antioxidant

In1940invention of silane coupling agent

In1943 invention of  isocyanate adhesive

In 1960invention of processing rubber 

In 1966invention of Cohedur

In1969invention of  antiscorching agent

In1970Invention of triazine accelerator

In1980invention of Manobond cobalt salt adhesive accelerator

 

The third generation

1980 to presentduring this periodthe main characteristics of rubbers are environmental protection and multifunction

 

1980-1981development of the rubber accelerator NS

In 1985launch of the environment-friendly accelerator MTT

1991 to presentdevelopment 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 ZBPDTBSICBBSTBzTDTIBTDZDIBCOTTOSZBECAS100 etc
