Cov lus qhia:

Nws yog tsuas yog siv rau kev hloov kho ntawm bismaleimide resin (BMI), uas tuaj yeem txo qis daim ntawv thov tus nqi ntawm BMI resin thiab txhim kho kev ua haujlwm thiab txheej txheem ntawm BMI resin. Cov tawv tawv, cov tiv tshav kub thiab cov cuab yeej molding ntawm BMI resin tau zoo dua. Yuav siv tau rau: insulation cov khoom siv hluav taws xob rwb thaiv tsev, tooj liab-clad Circuit Board, kub kub impregnating xim, insulating xim laminates, molding yas, thiab lwm yam. nplaum, thiab lwm yam ③ Aerospace txheej txheem khoom. Cov khoom muaj nuj nqi. Raws li cov tshuaj pleev xim rau cov roj hmab, ntxiv 1-3% BBA rau hauv cov roj hmab tuaj yeem txhim kho kev laus tiv thaiv ntawm cov roj hmab

Txoj kev kho kinetics thiab cov khoom siv ntawm cov hu ua ll bisphenol hloov kho cyanate ester resin tau kawm ： Diallyl bisphenol A(DBA) tau siv los hloov kho cyanate ester resin (CE). Txoj kev kho kom zoo sib xws ntawm qhov hloov kho cov txheej txheem tau suav los ntawm Flynn phab ntsa Ozawa hloov txoj kev hloov thiab Kissinger extremum txoj kev. Cov khoom siv kho tshuab thiab cov cuab yeej kev hloov kho ntawm lub zog kho tau raug kawm. Cov txiaj ntsig tau pom tias DBA muaj qhov pom tseeb pom tseeb thiab muaj kev cuam tshuam zoo tshaj plaws ntawm cyanate ester resin, qhov kev ua kom lub zog ntawm kev kho cov tshuaj tiv thaiv ntawm cov hloov kho uas muaj 5% DBA yog qhov tsawg tshaj plaws (62.16 kJ / mol). Thaum cov ntsiab lus ntawm DBA yog 10%, qhov cuam tshuam lub zog ntawm cov tshuaj tua tau zoo yog 2.07 zaug ntawm qhov tseeb ntawm cyanate ester resin. Qhov cia khoom thawm thiab iav hloov pauv kub ntawm CE cob muaj DBA tsawg

Diallyl bisphenol A(dabpa) tau siv los hloov kho bismaleimide cob nrog ether ketone qauv (ek-bmi). Txoj kev tua cov kinetics ntawm ek-bmi / dabpa system tau kawm los ntawm kev ntsuas hluav taws xob sib txawv ntawm cov roj calorimetry, Plaub kom hloov cov duab hluav taws xob infrared spectroscopy, Kissinger crane txoj kev ntsuas thiab qhov ntsuas kub ntawm cov txheej txheem ntxiv, cov khoom siv zog, lub zog tawv thiab thermal stability ntawm ek-bmi / dabpa system kawm. Cov txiaj ntsig pom tau hais tias cov txheej txheem tua cov txheej txheem ntawm ek-bmi / dabpa system yog 165 ℃ × 2 H + 180 × × 2 H + 238 × h 4 h, cov kev kho mob tom qab kho tau yog 250 × × 5 h, lub zog ua kom pom tseeb. yog 97.50 kJ / mol, qhov ntsuas zaus yog 2.22 × 107 s-1, thiab qhov tshuaj tiv thaiv kev txiav txim siab yog 0.9328, Lub zog tensile thiab khoov lub zog yog 89.42 MPa thiab 152 MPa, feem, thiab iav hloov qhov kub yog 278 ℃. Nws tseem tuaj yeem tswj cov khoom zoo ntawm 260 ℃. Qhov kev nyuaj siab hnyav thiab qhov tseem ceeb tshaj tawm lub zog tso tawm lub zog tuaj yeem ncav cuag 1.14 MPa · m0.5 thiab 276.6 J / m2, ntsig txog, qhia tau zoo ntawm cov pob txha tawv zoo, qhov pib txiav tawm qhov kub ntawm qhov system yog 412.95 ℃ (T5%), kev ceev cia tus nqi yog 37.91% ntawm 600 ℃ thiab 32.17% ntawm 900 ℃

Cov: 200kg / nruas.

Kev ceev faj cia: muab cia rau hauv qhov chaw txias, qhuav thiab muaj cua tshuab zoo.
