Ukwakhiwa kwereferensi ye-halogen-free flame retardant for water-based acrylic electronic adhesives
Kumasistimu e-acrylic asekelwe emanzini, amanani angeziwe e-aluminium hypophosphite (AHP) ne-zinc borate (ZB) kufanele anqunywe ngokusekelwe ezidingweni ezithile zohlelo lokusebenza (ezifana nesilinganiso sokuncipha komlilo, ukujiya koqweqwe, izidingo zokusebenza komzimba, njll.) kanye nemiphumela yako yokuhlangana. Ngezansi izincomo ezijwayelekile kanye nobubanzi bereferensi:
I. Isethenjwa Samanani Okwengezwa Kwesisekelo
Ithebula: Izengezo Nezincazelo Ezinconyiwe Zokubuyiswa Kwelangabi
| Uhlobo Lwe-Flame Retardant | Isengezo Esinconyiwe (wt%) | Incazelo |
| I-Aluminium Hypophosphite (AHP) | 5%~20% | I-phosphorus-based flame retardant; bhalansisisa ukubambezeleka kwelangabi ngokusebenza kahle nokuhambisana kwesistimu (amanani eqile angase athinte izakhiwo zemishini). |
| I-Zinc Borate (ZB) | 2%~10% | Isithuthukisi se-Synergistic; kunganciphisa ukuhlanganisa okuphelele uma kuhlanganiswe ne-AHP (izilinganiso eziphezulu ezidingekayo uma zisetshenziswa iyodwa). |
II. Ukuthuthukiswa Kwezilinganiso Ezihlangene
- Izilinganiso Ezijwayelekile Zenhlanganisela:
- I-AHP:ZB = 2:1 ~ 4:1(isb, 15% AHP + 5% ZB, isamba esingu-20%).
- Lungisa izilinganiso ngokuhlola, isibonelo:
- Isidingo esiphezulu sokubambezeleka komlilo:I-AHP 15%~20%, ZB 5%~8%.
- Izakhiwo zomzimba ezilinganiselwe:I-AHP 10%~15%, ZB 3%~5%.
- Imiphumela ye-Synergistic:
- I-Zinc borate ithuthukisa ukubambezeleka komlilo ngoku:
- Ukuzinzisa ukwakheka kwe-char (ukusebenzelana ne-aluminium phosphate ekhiqizwa yi-AHP).
- Ukudedela amanzi aboshwe ukuze amunce ukushisa futhi anciphise amagesi avuthayo.
III. Izinyathelo Zokuqinisekisa Zokuhlola
- Ukuhlolwa Kwesinyathelo Ngesinyathelo:
- Ukuhlola ngakunye:Qala ngokuhlola i-AHP (5%~20%) noma i-ZB (5%~15%) ngokuhlukene ukuze uthole ukuncipha komlilo (UL-94, LOI) nokusebenza kokunamathela (ukunamathela, ubulukhuni, ukumelana namanzi).
- Ukulungiselela okuyinhlanganisela:Ngemva kokukhetha inani le-AHP lesisekelo, engeza i-ZB ngokuqhubekayo (isb., 3% ukuya ku-8% lapho i-AHP ingu-15%) futhi ubone ukuthuthuka ekubambeni kwelangabi kanye nemiphumela engemihle.
- Izinkomba Zokusebenza Ezibalulekile:
- Ukuncipha komlilo:I-LOI (okuqondisiwe ≥28%), isilinganiso se-UL-94 (V-0/V-1), ukuminyana kwentuthu.
- Izinto ezibonakalayo:Ukwakhiwa kwefilimu, ukunamathela (ASTM D3359), ukumelana namanzi (akukho delamination ngemva kokucwiliswa kwama-48h).
IV. Ukucatshangelwa Okubalulekile
- Ukuzinza Kokusabalalisa:
- I-AHP i-hygroscopic—yoma ngaphambili noma sebenzisa okuhlukile okulungiswe phezulu.
- Sebenzisa izisabalalisi (isb, BYK-190, TEGO Dispers 750W) ukuze uthuthukise ukufana futhi uvimbele ukubola.
- Ukuhambisana kwe-pH:
- Amasistimu e-acrylic asekelwe emanzini ngokuvamile ane-pH engu-8-9; qinisekisa ukuthi i-AHP ne-ZB zihlala zizinzile (gwema i-hydrolysis noma ukubola).
- Ukuthobela Umthetho:
- I-AHP kufanele ihlangabezane nezidingo ze-RoHS ezingena-halogen; I-ZB kufanele isebenzise amamaki aphansi okungcola kwe-heavy-metal.
V. Izixazululo Ezihlukile noma Ezingezelelwe
- I-Melamine Polyphosphate (MPP):Ingaphinde ithuthukise ukubambezeleka komlilo uma ihlanganiswa ne-AHP (isb, 10% AHP + 5% MPP + 3% ZB).
- I-Nano Flame Retardants:I-Nano-grade ZB (isengezo sehliselwe ku-1%~3%) noma ama-hydroxide afakwe kabili (LDH) ukuze uthole imiphumela yokuvimbela ethuthukisiwe.
VI. Izincomo Ezifingqiwe
- Ukuqala ukwakha:I-AHP 10%~15% + ZB 3%~5% (inani elingu-13%~20%), bese ulungiselela.
- Indlela yokuqinisekisa:Hlola amasampuli amancane we-LOI ne-UL-94 ngenkathi uhlola izakhiwo zokukhanda.
