SBS yakagadziridzwa asphalt inoshandisa base asphalt seyakagadzirwa, inowedzera imwe chikamu cheSBS modifier, uye inoshandisa kuveura, kumutsa uye dzimwe nzira kuparadzira zvakaenzana SBS muasphalt. Panguva imwecheteyo, chimwe chikamu cheyakasarudzika stabilizer chinowedzerwa kugadzira SBS musanganiswa. zvinhu, kushandisa zvakanaka zvemuviri zvimiro zveSBS kugadzirisa asphalt.
Kushandiswa kwemagadzirirwo ekugadzirisa asphalt kune nhoroondo refu pasi rese. Pakati pezana remakore rechi19, nzira yevulcanization yakashandiswa kuderedza kupinda kweasphalt uye kuwedzera nzvimbo yekunyorova. Kuvandudzwa kweasphalt yakagadziridzwa mumakore makumi mashanu apfuura kwapfuura nematanho mana.
(1) 1950-1960, sanganisa rabha poda kana latex muasphalt, sanganisa zvakaenzana uye shandisa;
(2) Kubva ku1960 kusvika ku1970, styrene-butadiene synthetic rubber yakasanganiswa uye yakashandiswa pa-site nenzira ye latex muhuwandu;
(3) Kubva muna 1971 kusvika muna 1988, kuwedzera pakuenderera mberi kwekushandiswa kwerabha yakagadzirwa, thermoplastic resins yakashandiswa zvakanyanya;
(4) Kubva 1988, SBS yave zvishoma nezvishoma inotungamira yakagadziridzwa zvinhu.
Nhoroondo pfupi yekuvandudzwa kweSBS yakagadziridzwa asphalt:
★Kugadzirwa kwepasi rose kwezvigadzirwa zveSBS kwakatanga kuma1960.
★Muna 1963, Kambani yeAmerican Philips Petroleum yakashandisa nzira yekubatanidza kugadzira mutsara weSBS copolymer kekutanga, ine zita rekutengesa Solprene.
★Muna 1965, Kambani yeAmerican Shell yakashandisa tekinoroji yepolymerization yakaipa uye nhanho nhatu-nhanho dzakatevedzana yekudyara kugadzira chigadzirwa chakafanana uye kuwana kugadzirwa kwemaindasitiri, ine zita rekutengesa Kraton D.
★Muna 1967, kambani yeDutch Philips yakagadzira nyeredzi (kana radial) chigadzirwa cheSBS.
★Muna 1973, Philips akatanga nyeredzi SBS chigadzirwa.
★Muna 1980, Firestone Company yakatanga chigadzirwa cheSBS chinonzi Streon. Chigadzirwa che styrene chinosunga zvemukati chaive 43%. Chigadzirwa chacho chaive neyakanyungudika indekisi uye chainyanya kushandiswa kugadziridza epurasitiki uye inopisa kunyunguduka adhesives. Mushure mezvo, Kambani yeJapan yeAsahi Kasei, Kambani yeAnic yeItaly, Kambani yePetrochim yekuBelgium, nezvimwewo zvakatevedzana zvakagadzira zvigadzirwa zveSBS.
★Mushure mekupinda muma1990, nekuwedzera kuri kuramba kuchiwedzera kweSBS application fields, kugadzirwa kweSBS kwenyika kwakakura nekukurumidza.
★Kubva 1990, apo chigadzirwa cherabha cheBaling Petrochemical Company muYueyang, Hunan Province payakavaka mudziyo wekutanga wekugadzira weSBS munyika uine 10,000 matani akabuda pagore pachishandiswa tekinoroji yeBeijing Yanshan Petrochemical Company Research Institute, hunyanzvi hwekugadzira SBS hwekuChina hwakakura zvishoma nezvishoma. .
