Isophorone Diisocyanate (IPDI)Puas yog cov aliphatic diisicatic diisocyanate nrog molecular cov mis c ₁₂ h ₂ n ₂ o ₂ thiab txoj kev molecular hnyav ntawm 222.3. Raws li cov tseem ceeb raw cov ntaub ntawv ntawm kev lag luam polyurethane, IPDI tau pom tus nqi ntawm cov khoom siv ua haujlwm, cov khoom nplaum, thiab lwm yam.
1.1 qhov zoo ntawm cov qauv molecular
Lub nplhaib molecular ntawm iphone nkauj nplhaib thiab ob pawg Isocyanate (- nco) Txawm li cas los xij, vim nws tus me dua sticer cuam tshuam, kev ua haujlwm ntawm Zhong L yog 1.3-2.5 zaug ntawm Bo Bo Bo. Qhov no dual lub chaw nquag ua rau tus cwj pwm zoo tswj cov molecular chartses hauv synthes hauv polymer los yog ceg polyurethanes los ntawm kev kho cov tshuaj tiv thaiv.
1.2 sib piv ntawm cov kev ua si
Piv rau cov muaj ntxhiab diisocyanates xws li TDI thiab MDI, IPDI muaj qis dua cov tshuaj tiv thaiv (0.0013kpa, 25 degree), thiab kev ua haujlwm ntau dua.
Nws cov tshuaj tiv thaiv nrog cov pab pawg hydroxyl yog 4-5 zaug uas ntawm HDI (Hexamethylene Diisocyanate), uas tuaj yeem luv luv lub voj voog. Piv txwv li, nyob rau hauv kev npaj ntawm polyurethane elasteas, IPDI system tuaj yeem kho tau tsis pub dhau 2 teev, thaum lub sijhawm HDI yuav tsum muaj 8 teev.
1.3 Tus Kheej Kev Ntseeg Tus Kheej
IPDI tuaj yeem ua rau uriphatic uripetone Dimer ntawm 30-50℃nyob rau hauv nitrogen tiv thaiv, thiab qhov tshuaj tiv thaiv no tuaj yeem nrawm nrawm xws li 4-dimethylaminopyridine. Ib qho kev ua kom muaj zog polymerization ntawm Dimers tuaj yeem tsim cov txiaj ntsig loj uas muaj txiaj ntsig los npaj cov txheej txheem hluav taws xob siab nrog lub sijhawm kom qhuav rau lub sijhawm kom qhuav.
2.1 Kev Ua Haujlwm Siab Polyurethane
2.1.1|huab cua tiv taus txheej
IPDI Raws Polyurethane Txheej Txheem Muaj cov kev tiv thaiv UV zoo heev vim yog qhov tsis muaj Benzene nplhaib tsim qauv hauv lawv cov lwg me me. Hauv kev kho cov xim ntawm cov xim kho cov xim, cov txheej txheem npaj tau los ntawm cov kab lus zoo ntawm ipdi thiab cov xuab moos uas tau nrawm dua 60% ntawm tdi raws cov txheej txheem. Raws li cov ntaub ntawv thov los ntawm ib lub tuam txhab tsheb thoob ntiaj teb, cov qauv siv IPDI tuaj yeem txuas ntxiv lub neej ntawm 10 xyoo thiab txo cov nqi kho mob los ntawm 40%.
2.1.2 coj Elastomer
Lub polyurethane elastomer npaj los ntawm Ipdi thiab Polyether Polyol muaj lub zog ntawm 505, m, thiab ib lub zog tiv taus peb zaug uas muaj roj hmab ntuj.
Hauv tshav puam ntawm cov cua tshuab hluav taws xob, IPDI raws li elastomers yog siv rau cov hniav ua kom sov ntawm -40 Qib rau 50%, thiab txuas ntxiv lub neej pabcuam rau 20 xyoo.
2.1.3 Direborne Polyurethane
Lub DireBorne Polyurethane Topcoat nrog IPDI raws li tus neeg kho tus kws kho mob ua tiav VOC emissions<50g/L in the coating of wind turbine blades, which is 80% lower than fluorocarbon coatings. According to actual test data from a certain wind power enterprise, the IPDI water-based coating showed no bubbles after 960 hours of salt spray testing, maintained zero adhesion, and reduced overall cost by 35% compared to fluorocarbon systems.
2.2 Composite cov ntaub ntawv thiab cov nplaum
2.2.1 cov khoom siv nplaum nplaum
IPDI, raws li ib tug neeg kho tus sawv cev rau Polyurethane Adhesives hauv Composite Propellants, tuaj yeem txhim kho cov khoom siv tshuab cov khoom siv. Ib txoj kev tshawb fawb tau ua los ntawm ib pawg Aerospace ua tau hais tias kev siv IPDI kho cov khoom siv IPDI tuaj yeem ua tiav lub zog tensile hloov pauv ntawm<10% and a fracture elongation retention rate of>85% nyob rau hauv qhov kub ntawm -40℃rau +60} degree, sib ntsib ntawm cov dav hlau siab.
2.2.2 cov nplaum nplaum nplaum
Lub Adhesive npaj los ntawm IPDI thiab Polyester polyol muaj lub zog shear ntawm 35mpa thiab txhim kho cov ntsuas kub ntawm cov roj carbon fiber ntau. Raws li ib daim ntawv thov los ntawm qee yam kev tsim khoom lag luam aviation
2.3 Cov Khoom Siv Ua Haujlwm Tshwj Xeeb
2.3.1 kho qhov muag resin
Lub khoos phis tawm kho kho kho tshiab npaj los ntawm IPDI thiab hydroxyethyl metcrylate muaj qhov 32,5, ib qho kev hloov pauv ntawm 92%. Nws tuaj yeem siv rau cov lens kawg-kawg. Cov khoom ntsuas los ntawm cov ntsiab lus kho qhov muag pom tias Iddi raws li kev txhim kho hauv kev cuam tshuam rau PC lo ntsiab muag pc piv rau kev daj.
2.3.2 Cov Ntaub Ntawv Biomedical
Kev kho mob polyurethane npaj los ntawmIsophorone Diisocyanate (IPDI)Thiab Polycaprolactone muaj biocompatibilibility nyob rau hauv ISO 10993 tus qauv thiab tuaj yeem siv rau kev cog lus xws li kev siv lub siab tsim thiab vascular stents. Cov kev sim tsiaj tau pom tias kev ua haujlwm ntawm IPDI hauv Vivo tuaj yeem tswj tau nyob rau hauv 6-12 lub hlis, thiab tsis muaj kev teb mob.
Ruaj khov nyob rau hauv chav tsev kub thiab siab, isophorone diisocyanate reacts nrog cov tshuaj, Ehine, Amine, Amas, carbamate, urea, thiab lwm yam
Cov tshuaj tiv thaiv nrog hydrogen ntau: nws tuaj yeem tsim urea, amino acid ester, thiab hloov cov tshuaj tiv thaiv urea thiab hloov cov ntsiab lus ntawm isocyanate nrog amino pab pawg.
IPDI tuaj yeem ua kom acidic nrog carboryl compounds - hydrogen cov tshuaj tiv thaiv los tsim kev txiav txim siab oocyan, xws li Ipdethanate oocyanate tuaj yeem npaj los ntawm hydrogen ntawm hydrogen ntawm 40 degree.
Kev tiv thaiv tus kheej polymerization: nyob rau hauv nitrogen tiv thaiv thiab siab ib txwm muaj ntawm 30-50 degree, aliphatic urea diketone Dimer yog tsim. Thawj catalyst tuaj yeem yog 4-dimethylaminopyridine, 4-diethylaminopyridine, 4-piperidopyridine thiab {} (4-Methylpiperidinyl) pyridine. Lub co catalyst yog epoxy compound, xws li propylene oxide, Ethylene Oxide, Epoxy Butane thiab Epoxy chloropane.
IPDI Trimer yog tsim nyob rau hauv nitrogen tiv thaiv thiab kev ua kom zoo ntawm 50-90 degree. Cov catalyst tuaj yeem siv ua polycat 46. Vim muaj kev cuam tshuam ntawm ob lub ncos ntawm ipdi nrog asymmetric molecular qauv sib txawv. Thaum ib - nco txog cov kev ua yeeb yam ntawm seem uas tshuav - nco qab. Tom qab txiav kev tsim, polymerization inhibitors xws li methyl toluenesulfonate, phosphoric acid, thiab lwm yam ntxiv kom tsis txhob ua tiav polymerization thiab kho.
Polymerization rau Daim Ntawv Polymers: IPDI tuaj yeem ncaj qha polymerize (dea) los ua cov ntoo polymer uas tsis muaj lwm yam kev sib txuas ua ke. Ntxiv mus, vim hais tias cov nquag hydrogen kev ua si ntawm - NH thiab - Huag pawg hauv DEA sib txawv, cov kev ua tau zoo yuav tsim hyperbranched polymers. Nws kuj tseem tuaj yeem muaj kev cuam tshuam nrog polyamide los hloov cov tshuaj yej, uas tau nrawm dua li cov tshuaj tiv thaiv nrog cov polyols, thiab lub sijhawm ua kom muaj zog ntau. Yog hais tias nws rov qab los nrog dej, hydrolysis ntawm lub pab pawg ua haujlwm yuav tsim tawm nrog tshaj IsoSananate los ua kom muaj urea thiab cross sib txuas. Cov tshuaj tiv thaiv no tuaj yeem ua rau ib qho kev tivthaiv ib qho, tab sis noo noo yuav tsum tiv thaiv thaum lub sijhawm cia.
Isophorone Diisocyanate (IPDI)tebchaw tsis muaj nyob rau hauv xwm. Qhov ntxov tshaj plaws isocyanate compound tau npaj los ntawm British Chemist Wurtz xyoo 1849 los ntawm kev txiav txim siab ob chav ntawm Alkyl sulfate thiab Potassium Cyanate.
Tom qab ntawd, nyob rau xyoo 1850, Asmeskas Chemist Hofmann tau Phenyyl Isocyanate los ntawm kev siv Benzamide.
Xyoo 1884, xibfwb Hentsschael ntawm lub teb chaws Yelemees thiab lwm tus neeg sab nrauv Isocyanate Isine lossis Eine ntsev nrog Acyl chloride. Qhov tshuaj tiv thaiv no tau tso ib lub hauv paus uas yog lub hauv paus rau kev lag luam kev lag luam ntawm isocyanate tebchaw.
Hauv xyoo 1940 thiab xyoo 1950, lub proterify supiftion cov txheej txheem hauv cov kua theem photogasification txheej txheem tau yog siv los npaj adi. Adi yog hais txog aliphatic thiab alicyclic diisocyanates. Cov ntau yam tseem ceeb muaj HDI, IPDI thiab H12mdi. Tsis tas li ntawd, nws tseem suav nrog Tetramethyl Benzene DiisChylene DiisCyanate (XDL) Methylcychanate (HTDL)
Xyoo 1960, German Hurst lub tuam txhab tsim cov hom tshiab ntawm isocyanate, npe Isophorone Diisocyanate.
Xyoo 1989, Bayer tuam txhab ua ntej tau qhia cov thev naus laus zis ntawm kev npaj adi txheej txheem maj mam los ua cov thev naus laus zis thev naus laus zis ntawm kev npaj adi.
Thaum Tuam Tshoj pib tsim Polyurethane Resin Txheej Txheem nyob rau xyoo 1950, nws tau pib hu rau kev siv thiab kev tsim khoom Isocyanate teb.
Cim npe nrov: Isophorone Diisocyanate (IPDI) CAS 4098-71-9, cov neeg muag khoom, chaw tsim khoom, chaw tsim khoom, yuav khoom, rau muag
