Glycidyl Methacrylate (GMA) imonomer ine acrylate double bonds uye epoxy groups. Acrylate double bond ine reactivity yakakwira, inogona kuzviitira polymerization reaction, uye inogonawo kuumbwa copolymer nedzimwe monomers dzakawanda; epoxy group inogona kuita reaction ne hydroxyl, amino, carboxyl kana acid anhydride, zvichiunza mapoka anoshanda zvakanyanya, nokudaro zvichiunza mashandiro akawanda kuchigadzirwa. Nokudaro, GMA ine mashandisirwo akasiyana-siyana mu organic synthesis, polymer synthesis, polymer modification, composite materials, ultraviolet curing materials, coatings, adhesives, dehwe, chemical fiber papermaking, printing and dyeing, nedzimwe nzvimbo dzakawanda.

Kushandiswa kweGMA mukugadzira upfu

Mapendi eAcrylic powder imhando yakakura yependi dzeupfu, dzinogona kukamurwa kuita mahydroxyl acrylic resins, carboxyl acrylic resins, glycidyl acrylic resins, uye amido acrylic resins zvichienderana nemarudzi akasiyana ekupisa anoshandiswa. Pakati pawo, glycidyl acrylic resin ndiyo inonyanya kushandiswa pendi yekupisa. Inogona kugadzirwa kuita mafirimu ane mapendi ekupisa akadai sepolyhydric hydroxy acids, polyamines, polyols, polyhydroxy resins, uye hydroxy polyester resins.

Methyl methacrylate, glycidyl methacrylate, butyl acrylate, styrene zvinowanzo shandiswa kugadzira free radical polymerization kugadzira GMA type acrylic resin, uye dodecyl dibasic acid inoshandiswa semushonga wekupisa. Acrylic powder coating yakagadzirwa ine mashandiro akanaka. Maitiro ekugadzira anogona kushandisa benzoyl peroxide (BPO) uye azobisisobutyronitrile (AIBN) kana musanganiswa wavo sekutanga. Huwandu hweGMA hune simba guru pakushanda kwe coating film. Kana huwandu hwacho huri hudiki, crosslinking degree ye resin yakaderera, curing crosslinking points shoma, crosslinking density ye coating film haina kukwana, uye coating film haina simba.

Kushandiswa kweGMA mukugadzirisa polymer

GMA inogona kuiswa papolymer nekuda kwekuvapo kwe acrylate double bond ine activity yakakwira, uye epoxy group iri muGMA inogona kuita nemapoka akasiyana-siyana anoshanda kuti igadzire functionalized polymer. GMA inogona kuiswa ku modified polyolefin nenzira dzakadai se solution grafting, melt grafting, solid phase grafting, radiation grafting, nezvimwewo, uye inogonawo kugadzira functionalized copolymers ne ethylene, acrylate, nezvimwewo. Aya functionalized polymers anogona kushandiswa se toughening agents kusimbisa mapurasitiki einjiniya kana se compatibilizers kuvandudza blend systems.

Chinhu chinowanzo shandiswa pakugadzirisa polyolefin neGMA idicumyl peroxide (DCP). Vamwe vanhu vanoshandisawo benzoyl peroxide (BPO), acrylamide (AM), 2,5-di-tert-butyl peroxide. Zvinhu zvinotanga zvakaita se oxy-2,5-dimethyl-3-hexyne (LPO) kana 1,3-di-tert-butyl cumene peroxide. Pakati pazvo, AM ine simba guru pakuderedza kuora kwepolypropylene kana ikashandiswa semutangi. Kubatanidzwa kweGMA papolyolefin kuchaita kuti pave nekuchinja kwechimiro chepolyolefin, izvo zvinozokonzera shanduko yechimiro chepamusoro chepolyolefin, chimiro cherheological, chimiro chekupisa uye chimiro chemakanika. GMA graft-modified polyolefin inowedzera polarity ye molecular chain uye panguva imwe chete inowedzera polarity yekumusoro. Nokudaro, angle yekubatana kwekumusoro inoderera sezvo chiyero chekubatanidza chichiwedzera. Nekuda kwekuchinja kwechimiro chepolymer mushure mekushandurwa kweGMA, zvichakanganisawo chimiro chayo chekristaro uye chemakanika.

Kushandiswa kweGMA mukugadzirwa kweUV resin inorapika

GMA inogona kushandiswa mukugadzira maresini anorapika eUV kuburikidza nenzira dzakasiyana-siyana dzekugadzira. Imwe nzira ndeyekutanga kuwana prepolymer ine macarboxyl kana maamino groups padivi pecheni kuburikidza ne radical polymerization kana condensation polymerization, uye wobva washandisa GMA kuita nemapoka aya anoshanda kuti uunze mapoka anonzwa chiedza kuti uwane resin inorapika. Mu copolymerization yekutanga, macomonomers akasiyana anogona kushandiswa kuwana mapolymers ane hunhu hwakasiyana hwekupedzisira. Feng Zongcai nevamwe vake vakashandisa 1,2,4-trimellitic anhydride uye ethylene glycol kuti vaite kuti mapolymers ane hyperbranched, uye vakazounza mapoka anonzwa chiedza kuburikidza neGMA kuti vapedzisire vawana resin inorapika ine alkali solubility iri nani. Lu Tingfeng nevamwe vakashandisa poly-1,4-butanediol adipate, toluene diisocyanate, dimethylolpropionic acid uye hydroxyethyl acrylate kutanga vagadzira prepolymer ine photosensitive active double bonds, uye vozoiisa kuburikidza neGMA. Mamwe ma double bonds anorapika nyore nyore anobviswa ne triethylamine kuti awane emulsion ye polyurethane acrylate inofambiswa nemvura.
