Igwe ọkụ UV na-ekpo ọkụ gwọrọ organic / inorganic ngwakọ bụ ihe mejupụtara nke Waterborne UV resin na ihe inorganic.A na-ewebata uru nke ihe inorganic dị ka akwa mkpuchi mkpuchi na ihu igwe dị elu na resin iji melite njirimara zuru oke nke ihe nkiri a gwọrọ.Site na iwebata ụmụ irighiri ihe dị ka nano-SiO2 ma ọ bụ montmorillonite n'ime usoro ọgwụgwọ UV site na usoro mgbasa ozi ozugbo, usoro sol-gel ma ọ bụ usoro intercalation, enwere ike ịkwadebe UV curing organic / inorganic hybrid system.Na mgbakwunye, enwere ike iwebata organosilicon monomer n'ime agbụ molekụla nke UV oligomer aqueous.
A kwadebere ude mmiri Organo / inorganic ngwakọ (Si PUA) site na iwebata ndị otu polysiloxane n'ime akụkụ dị nro nke polyurethane nwere ọdụ abụọ hydroxybutyl polydimethylsiloxane (PDMS) na diluting na acrylic monomers.Mgbe ọgwụgwọ gasịrị, ihe nkiri agba nwere ezigbo ihe anụ ahụ, akụkụ kọntaktị dị elu na nkwụsị mmiri.A na-akwado polyurethane hyperbranched hybrid na ìhè gwọrọ hyperbranched polyurethane site na polyhydroxy hyperbranched polyurethane, succinic anhydride, silane njikọ njikọ KH560, glycidyl methacrylate (GMA) na hydroxyethyl methacrylate.Mgbe ahụ, a kwadebere Si02 / Ti02 organic-inorganic hybrid sol nke ìhè gwọrọ hyperbranched polyurethane site na ịgwakọta na hydrolyzing na tetraethyl orthosilicate na n-butyl titanate n'ụzọ dị iche iche.Nsonaazụ na-egosi na site na mmụba nke ọdịnaya inorganic, pendulum siri ike nke mkpuchi ngwakọ na-abawanye na nhụsianya elu na-abawanye.The elu àgwà nke SiO2 ngwakọ mkpuchi dị mma karịa nke Ti02 ngwakọ mkpuchi.
3 usoro ọgwụgwọ abụọ
Iji dozie adịghị ike nke atọ akụkụ ọgwụgwọ nke Waterborne UV resin na ọgwụgwọ nke oké mkpuchi na acha usoro, na melite keukwu Njirimara nke ihe nkiri, na-eme nchọpụta mepụtara a dual ọgwụgwọ usoro na-ejikọta ìhè ọgwụgwọ na ndị ọzọ na-agwọ usoro.Ka ọ dị ugbu a, ọgwụgwọ ọkụ, ọgwụgwọ okpomọkụ, ọgwụgwọ ọkụ / redox ọgwụgwọ, ọgwụgwọ ọkụ radical free / cationic ìhè ọgwụgwọ na ọkụ na-agwọ ọrịa / mgbochi mmiri bụ usoro ọgwụgwọ abụọ a na-ahụkarị, na etinyere ụfọdụ sistemu.Dịka ọmụmaatụ, nrapado nchedo eletrọnịkị UV bụ usoro ọgwụgwọ abụọ nke ọgwụgwọ ọkụ / redox ma ọ bụ ọgwụgwọ ọkụ / mgbochi mmiri.
A na-ewebata monomer ethyl acetoacetate methacrylate (amme) na-arụ ọrụ n'ime mmiri mmiri polyacrylic, na otu ọkụ ọkụ ewepụtara site na Michael mgbakwunye mmeghachi omume na obere okpomọkụ iji synthesize okpomọkụ ọgwụgwọ / uv curing waterborne polyacrylate.Akọrọ na okpomọkụ mgbe niile nke 60 Celsius C, 2 x 5 N'okpuru ọnọdụ nke 6 kW elu-nrụgide mercury oriọna irradiation, ike nke resin mgbe e guzobere film bụ 3h, mmanya na-eguzogide bụ 158 ugboro, na alkali iguzogide bụ 24. awa.
4 epoxy acrylate / polyurethane acrylate composite system
Epoxy acrylate mkpuchi nwere uru nke ịdị elu siri ike, ezigbo adhesion, elu gloss na ezigbo nguzogide kemịkalụ, ma ọ nwere adịghị ike mgbanwe na brittleness.Mmiri polyurethane acrylate nwere njiri mara mma na-eguzogide iyi na mgbanwe, mana ihu igwe adịghị mma.N'iji mgbanwe kemịkalụ, ngwakọta anụ ahụ ma ọ bụ ụzọ ngwakọ iji mejupụta resin abụọ nke ọma nwere ike imeziwanye arụmọrụ nke otu resin ma nye egwuregwu zuru oke maka uru ha, iji mepụta usoro ọgwụgwọ UV dị elu yana uru abụọ ahụ.
5 fotoinitiator macromolecular ma ọ bụ polymerizable
Ọtụtụ photoinitiators bụ aryl alkyl ketone obere ụmụ irighiri ihe, nke na-enweghị ike ire ere kpamkpam mgbe ọkụ gwọchara.Ihe ndị fọdụrụnụ obere ụmụ irighiri ihe ma ọ bụ ngwaahịa photolysis ga-akwaga n'elu mkpuchi, na-eme ka odo ma ọ bụ isi ísì, nke ga-emetụta arụmọrụ na ngwa nke ihe nkiri a gwọrọ.Site na iwebata photoinitiators, acryloyl otu na hydrophilic otu n'ime hyperbranched polymers, ndị nchọpụta synthesized waterborne macromolecular polymerizable photoinitiators iji merie ọghọm nke obere molekul photoinitiators.
