【摘要】：采用生物質(zhì)松香酸酐固化劑,通過(guò)配方設(shè)計(jì)和篩選,由配方體系成膜性、膠膜儲(chǔ)存期、膠膜狀態(tài)及DSC測(cè)試初步確定生物質(zhì)環(huán)氧樹脂體系的配方組成環(huán)氧樹脂/固化劑/促進(jìn)劑的質(zhì)量比為100/60/3~4。由動(dòng)態(tài)/穩(wěn)態(tài)DSC測(cè)試和錐板旋轉(zhuǎn)黏度計(jì)對(duì)體系的固化特征溫度和黏度-溫度-時(shí)間特性進(jìn)行研究,結(jié)果確定樹脂體系可在120~140℃完成固化,熱熔法預(yù)浸溫度范圍60~85℃,其黏度在1500~5000mPa·s,其中70℃操作時(shí)間達(dá)180min。最后由紅外光譜和DSC對(duì)生物質(zhì)環(huán)氧體系的固化反應(yīng)機(jī)理進(jìn)行了研究。
[Abstract]:The curing agent of biomass rosin anhydride was used. Through the formulation design and screening, the film formation and storage period of the film were obtained by the formulation system. The composition of epoxy resin / curing agent / accelerator mass ratio is 100 / 60 / 3 / 4. The curing characteristic temperature and viscosis-temperature-time characteristic of the system were studied by dynamic / steady state DSC test and cone plate rotary viscometer. The results show that the resin system can be cured at 120 ~ 140 鈩，
