Cov roj hmab ua kua-Amino-terminated nitrile butadiene roj hmab (ATBN)
Cov Khoom thiab Kev Siv
ATBN yog cov roj hmab nitrile kua nrog cov amino functional pawg ntawm ob qho kawg ntawm cov saw molecular, uas tuaj yeem kho nrog isocyanate curing agent lossis reacted nrog epoxy pawg.
Nws muaj cov roj zoo tsis kam, tiv taus kub, tiv taus kev sib txhuam, muaj zog nplaum, uas ua rau epoxy resin tawv tuaj yeem txo qhov kub gelatinization thiab kub kho ntawm epoxy resin.
Feem ntau siv rau hauv epoxy resin toughening agent, tuaj yeem txhim kho qhov toughness ntawm cov ntaub ntawv sib xyaw, txhim kho lub zog shear thiab lub zog tev tawv, kuj tseem siv tau ua cov nplaum thiab sealant sib cais.
