Chinese net on Feburary 10 dispatch (Wang Li division) on Feburary 10, the reporter understands from Sichuan university, group of academician of Wang Yuzhong of institute of Sichuan university chemistry got international material field a few days ago Materials Today of top class periodical invites, reclaim around what epoxy resin reachs its composite material the domain considers to make progress, compose published “Recovery Of Epoxy Thermosets And Their Composites” to sum up a paper, summed up what epoxy resin reachs its composite material to reclaim research current situation, was based on a group to put forward to reclaim in the research achievement of this domain strategy and methodological term use a proposal, to be based on fountainhead reclaim politic (SRS(Source-baSed Recovery Strategy) , ratioNal Design Of Recyclable Thermosets) and be based on endmost to reclaim politic (ERS(End-baSed Recovery Strategy) , two kinds of the epoxy resin of Recovery Approaches Of Existing Thermosets) reclaim strategy undertook summing up, reclaim with chemistry from physics two respects development discussed those who be based on ERS to wind debit way.
“ this paper emphasized chemistry reclaiming in the process important but the issue that is ignored easily, include those who enhance degradation process to pass pledge and conduct heat, the solvent effect that takes separate course seriously, reclaiming litter should make full use of in the design each constituent and give attention to two or morethings upgrade reclaiming economy and environmental protection sex. Chief introduces to the reporter related institute of chemistry of ” Sichuan university, this paper points out, SRS strategy can realize the ” of “ closed circuit of epoxy resin to reclaim, but if where,hold the key that integral performance is being improved while reversible trends is characteristic is prospective research. “ERS strategy basically reclaims for ’ of ‘ open loop, it is to realize epoxy resin to upgrade reclaiming important research direction. The author put forward to reclaim in order to apply for oriented chemistry train of thought, reclaim process should at the same time alternative degradation mixes give attention to two or morethings efficient reframe; Develop alternative activator and functional dissolvent, build reframe newly of child of methodological implementation degradation make full use of and of material of much constituent epoxy resin the key that reclaiming completely is prospective research and key. ”
As we have learned, epoxy resin has superior mechanical performance, dielectric protecties, stick receive function and chemical stability, be applied extensively at composite material, electron to enclose the domain such as material, coating and adhesive. The demand that the whole world increases increasingly to the clean the sources of energy such as wind energy drove the production of epoxy resin and application, the crop of epoxy resin composite material that is used at lamina of wind- driven turbine grows quickly. However, as new product upgrade the end of replacement and service life, a large number of epoxy resin and its composite material are about to retire. How to use angle to set out from environmental protection and resource, the green that realizes epoxy resin and its composite material is efficient high cost is changed reclaim use, it is the one big challenge that faces at present.
This paper is published at Materials Today, sichuan university is the first unit, academician of Wang Yuzhong of institute of this school chemistry and Professor Xu Shimei are writer of this paper newsletter, zhao Xu of graduate student of 2020 class doctor is the first author. Article coauthor includes Sichuan university Chen Li to teach, liu Xuehui's assistant researcher and Long Yuwei of doctoral graduate student. This job got the support of key laboratory of state of funds of basic research of national science foundation, 111 plans, central college and project of high polymer material.
