Roj hmab additives yog cov khoom siv tshuaj zoo ntxiv thaum lub sijhawm ua cov roj hmab ntuj thiab cov roj hmab hluavtaws (xws li hu ua "raws li roj hmab") rau hauv cov khoom siv roj hmab, uas yog siv los tsim cov khoom siv roj hmab nrog kev ua haujlwm, tswj lub neej kev pab cuam ntawm cov khoom siv roj hmab. , thiab txhim kho kev ua haujlwm ntawm cov roj hmab sib txuas.Rubber additives ua lub luag haujlwm tseem ceeb hauv kev hloov kho cov qauv ntawm cov khoom siv roj hmab, kev tsim cov khoom tshiab, kev txhim kho cov roj hmab ua technology, kev txhim kho cov khoom siv roj hmab kev ua tau zoo thiab zoo, thiab yog cov khoom siv tsis tseem ceeb hauv kev lag luam roj hmab.
Cov roj hmab ntuj hauv ntiaj teb tau tshawb pom los ntawm Columbus thaum nws pom lub Ntiaj Teb Tshiab hauv 1493, tab sis nws tsis yog txog 1839 uas leej faj tuaj yeem siv los ua tus neeg sawv cev vulcanizing rau cross-link rubber, yog li muab nws cov txiaj ntsig zoo.Txij thaum ntawd los, lub ntiaj teb roj hmab kev lag luam tau yug los, thiab kev lag luam roj hmab kuj tsim.
Roj hmab additives tuaj yeem muab faib ua peb tiam raws li lawv cov keeb kwm kev loj hlob, raws li cov lus qhia hauv qab no.
Thawj tiam ntawm roj hmab additives 1839-1904
Cov khoom siv roj hmab ntxiv ntawm lub sijhawm no yog sawv cev los ntawm inorganic vulcanization accelerators.Kev lag luam roj hmab tau nkag mus rau lub sijhawm ntawm inorganic vulcanization accelerators, tab sis nws kuj muaj teeb meem xws li kev nce qib qis thiab kev ua haujlwm tsis zoo ntawm vulcanization.
● 1839 Tshawb nrhiav cov nyhuv ntawm sulfur ntawm roj hmab vulcanization
● 1844 Tshawb nrhiav inorganic vulcanization accelerators
● 1846 Pom tau tias sulfur monochloride tuaj yeem ua rau roj hmab "txias vulcanize", siv amine carbonate ua tus neeg sawv cev foaming
● 1904 Tshawb nrhiav cov vulcanization active neeg sawv cev zinc oxide thiab pom tias cov pa roj carbon dub muaj zog ntxiv rau cov roj hmab
Ob tiam roj hmab additives 1905-1980
Cov khoom siv roj hmab ntxiv ntawm lub sijhawm no tau sawv cev los ntawm cov organic vulcanization accelerators.Cov organic roj hmab vulcanization accelerator ua ntej, aniline, muaj kev txhawb nqa vulcanization, uas tau tshawb pom los ntawm German chemist Oenslaber hauv xyoo 1906 hauv kev sim hauv Tebchaws Meskas.

Peb tiam roj hmab additives 1980～
Tom qab ntau tshaj 100 xyoo ntawm kev tshawb fawb, nws tsis yog kom txog rau thaum xyoo 1980s uas muaj ntau yam roj hmab additives pib nce thiab cov kab ke ua kom paub tab.Nyob rau theem no, cov khoom siv roj hmab ntxiv yog cov yam ntxwv ntawm ntsuab thiab ntau yam khoom siv.
● 1980-1981 Txoj kev loj hlob ntawm accelerator NS pib hauv Suav teb
● 1985 Launch MTT
● 1991 ~ Nruam tsim thiab pib siv ib puag ncig tus phooj ywg uas tsis yog nitrosamine lossis nitrosamine muaj kev nyab xeeb ntxiv xws li thiram, sulfonamide, zinc ntsev accelerators, vulcanizing agents, anti coking agents, plasticizers, thiab lwm yam, ZBPD, TBSI, CBBS, TBzTD, TIBTD, TIBTM, ZDIBC, OTTOS, ZBEC, AS100, E / C, DBD thiab lwm yam khoom tau raug tsim ua tiav.
