Glycidyl Methacrylate (GMA) ni monomer ifite byombi ya acrylate inshuro ebyiri hamwe nitsinda rya epoxy. Acrylate double bond ifite reaction nyinshi, irashobora kwikorera-polymerisation reaction, kandi irashobora no gukoporora hamwe nabandi benshi ba monomers; epoxy group irashobora kwitwara hamwe na hydroxyl, amino, carboxyl cyangwa acide anhydride, itangiza amatsinda menshi akora, bityo bikazana imikorere myinshi kubicuruzwa. Kubwibyo, GMA ifite uburyo bunini cyane bwo gukoresha muri synthesis synthesis, polymer synthesis, guhindura polymer, ibikoresho bikomatanya, ibikoresho byo gukiza ultraviolet, gutwikira, gufatira, uruhu, gukora fibre fibre, gucapa no gusiga irangi, nibindi bice byinshi.

Gukoresha GMA mugutwika ifu

Ifu ya Acrylic nicyiciro kinini cyamavuta yifu, ishobora kugabanywamo hydroxyl acrylic resin, carboxyl acrylic resin, glycidyl acrylic resin, hamwe na amido acrylic resin ukurikije uburyo butandukanye bwo gukiza bwakoreshejwe. Muri byo, glycidyl acrylic resin ni yo ifu ikoreshwa cyane. Irashobora kubumbwa muma firime ifite imiti ikiza nka acide polyhydric hydroxy acide, polyamine, polyol, polyhydroxy resin, hamwe na hydroxy polyester resin.

Methyl methacrylate, glycidyl methacrylate, butyl acrylate, styrene mubisanzwe bikoreshwa muburyo bwa polymerisime yubusa kugirango bahuze ubwoko bwa GMA acrylic resin, na acide dodecyl dibasic ikoreshwa nkumuti ukiza. Ifu ya acrylic ifu yateguwe ifite imikorere myiza. Inzira ya synthesis irashobora gukoresha benzoyl peroxide (BPO) na azobisisobutyronitrile (AIBN) cyangwa imvange zabo nkabitangiza. Ingano ya GMA igira uruhare runini mumikorere ya firime. Niba umubare ari muto cyane, urwego rwo guhuza resin ruri hasi, ingingo zo gukiza zifatika ni nke, ubwuzuzanye bwa firime ya coating ntabwo buhagije, kandi ingaruka zo guhangana na firime ya coating ni mbi.

Gukoresha GMA muguhindura polymer

GMA irashobora kwomekwa kuri polymer bitewe nuko habaho guhuza kabiri kwa acrylate hamwe nibikorwa byinshi, kandi itsinda rya epoxy ririmo GMA rirashobora kwitwara hamwe nandi matsinda atandukanye akora kugirango bakore polymer ikora. GMA irashobora kwomekwa kuri polyolefine yahinduwe hakoreshejwe uburyo nko gushushanya igisubizo, gushonga gushonga, gushushanya icyiciro gikomeye, guhuza imirasire, nibindi, kandi birashobora no gukora kopi yimikorere ikora hamwe na Ethylene, acrylate, nibindi. Kuri gukaza umurego plastike yubuhanga cyangwa nkabahuza kugirango tunoze guhuza sisitemu ivanze.

Intangiriro ikoreshwa kenshi muguhindura polyolefin na GMA ni dicumyl peroxide (DCP). Abantu bamwe bakoresha kandi benzoyl peroxide (BPO), acrylamide (AM), 2,5-di-tert-butyl peroxide. Abatangije nka oxy-2,5-dimethyl-3-hexyne (LPO) cyangwa 1,3-di-tert-butyl cumene peroxide. Muri byo, AM igira ingaruka zikomeye mukugabanya iyangirika rya polypropilene iyo ikoreshejwe nkintangiriro. Guteranya GMA kuri polyolefin bizaganisha ku guhindura imiterere ya polyolefine, bizatera ihinduka ryimiterere yubuso bwa polyolefin, imiterere ya rheologiya, imiterere yubushyuhe hamwe nubukanishi. GMA graft-yahinduwe polyolefin yongerera polarite yumunyururu wa molekile kandi icyarimwe ikongera ubuso bwa polarite. Kubwibyo, ubuso bwo guhuza inguni buragabanuka uko igipimo cyo guterana cyiyongera. Bitewe nimpinduka mumiterere ya polymer nyuma yo guhindura GMA, bizanagira ingaruka kuri kristaline na mashini.

Gukoresha GMA muri synthesis ya UV ikiza resin

GMA irashobora gukoreshwa muri synthesis ya UV ikiza ibisigazwa binyuze munzira zitandukanye. Uburyo bumwe ni ukubanza kubona prepolymer irimo amatsinda ya carboxyl cyangwa amino kumurongo wuruhande binyuze muri polymerisation radical cyangwa kondensation polymerisation, hanyuma ugakoresha GMA kugirango ukore hamwe naya matsinda akora kugirango utangire amatsinda yifotora kugirango ubone resin ifotora. Muri copolymerisation yambere, abakomisiyoneri batandukanye barashobora gukoreshwa kugirango babone polymers nibintu bitandukanye byanyuma. Feng Zongcai n'abandi. yakoresheje 1,2,4-trimellitike anhydride na Ethylene glycol kugirango yifate muguhuza polymers hyperbranched polymers, hanyuma ashyiraho amatsinda yifotora yifashishije GMA kugirango amaherezo abone resin ifotora hamwe na alkali nziza. Lu Tingfeng nabandi bakoresheje poly-1,4-butanediol adipate, toluene diisocyanate, dimethylolpropionic acide na hydroxyethyl acrylate kugirango babanze bashushanye prepolymer hamwe na fotosensitif ikora inshuro ebyiri, hanyuma bayimenyekanishe binyuze muri GMA Imirongo ibiri yoroheje-ishobora gukosorwa itabangamiwe na triethylamine. kubona amazi ya polyurethane acrylate emulion.
