SBS Kev Hloov Asphalt siv cov khoom siv asphalt li cov khoom siv raw, thiab siv tej yam sib npaug ntawm SBS hloov kho, thiab siv cov txheej txheem sib dhos, thiab lwm yam kev sib tsoo hauv cov asphalt. Nyob rau tib lub sijhawm, ib qho kev faib ua feem ntawm cov stabilizer tshwj tseg ntxiv los ua cov s lo. Cov khoom siv, siv cov khoom siv lub cev zoo ntawm SBS kom hloov assphalt.
Kev siv ntawm cov hloov kho kom hloov aspify asphalt muaj keeb kwm kev thoob ntiaj teb ntev. Nyob rau hauv nruab nrab-xyoo pua puv 19, txoj kev vulcanization tau siv los txo cov kev nkag mus aspetration asphalt thiab nce cov khoom muag muag taw tes. Txoj kev txhim kho ntawm kev hloov kho asphalt hauv 50 xyoo dhau los tau kwv yees li ntawm plaub theem.

(1) 1950-1960, ncaj qha muab cov roj hmab roj hlau ncaj qha los yog lo lus zoo kom asphalt, tov tusyees thiab siv;
(2) txij xyoo 1960 txog 1970, STyrene-butadiene cov roj hmab hluavtaws hluavtaws tau sib xyaw thiab siv nyob rau hauv daim ntawv ntawm latex hauv kev faib ua faib;
(3) Txij xyoo 1971 txog 1988, ntxiv rau kev txuas ntxiv roj hmab roj hmab, thermoplastic resins tau siv dav;
(4) Txij li thaum 1988, SBS tau maj mam dhau los ua cov khoom hloov kho.
Ib nyuag keeb kwm ntawm kev txhim kho ntawm SBS hloov asphalt:
★ Lub ntiaj teb kev tsim khoom lag luam ntawm cov khoom lag luam SBS pib xyoo 1960.
★ xyoo 1963, cov neeg Asmeskas cov tuam txhab roj av siv txoj kev txuas txuas rau cov kab cops copolymer thawj zaug, nrog lub npe lag luam solprene.
Lub tuam txhab xyoo 1965, American lub tuam txhab siv tsis zoo ion kev siv thev naus laus zis los tsim cov khoom lag luam zoo sib xws thiab ua tiav cov khoom lag luam Kraton D.
★ xyoo 1967, Dutch tuam txhab Philips Tsim lub hnub qub (lossis radial) SBS khoom.
Xyoo 1973, Philips Lijled Star SBS khoom.
★ xyoo 1980, lub tuam txhab fira tau ua tiav rau cov khoom SBS hu ua Streon. Cov khoom ntawm cov ntsiab lus styrene khi yog 43%. Cov khoom lag luam muaj siab melt index thiab feem ntau yog siv rau kev hloov yas hloov kho thiab kub yaj cov nplaum. Tom qab, Nyiv Asahi Kasei tuam txhab, Ltalis lub tuam txhab qub, Belgium cov tuam txhab Petrochim, thiab lwm yam tau ua tiav cov khoom SBS.
Tom qab nkag mus rau xyoo 1990, nrog kev nthuav dav txuas ntxiv ntawm SBS daim ntawv thov teb, lub ntiaj teb SBS ntau lawm tau tsim sai.
★ Txij li xyoo 1990, thaum synthetic roj hmab cog ntawm baling petrochemical tuam txhab kev tshawb fawb lub teb chaws lub tuam txhab
