Mawonekedwe a halogen-free flame retardant reference for water-based acrylic electronic adhesives
M'makina a acrylic opangidwa ndi madzi, kuchuluka kwa aluminiyamu hypophosphite (AHP) ndi zinc borate (ZB) ziyenera kutsimikiziridwa malinga ndi zofunikira za ntchito (monga kutentha kwa moto, makulidwe a zokutira, zofunikira za thupi, ndi zina zotero) ndi zotsatira zake zogwirizana. M'munsimu muli zovomerezeka ndi mafotokozedwe osiyanasiyana:
I. Baseline Addition Amounts Reference
Table: Zowonjezera ndi Mafotokozedwe a Flame Retardant
| Flame Retardant Type | Zowonjezera Zovomerezeka (wt%) | Kufotokozera |
| Aluminium Hypophosphite (AHP) | 5% ~ 20% | Phosphorous-based flame retardant; sungani bwino kubwezeredwa kwamoto ndi kuyanjana kwadongosolo (kuchulukirachulukira kungakhudze makina amakina). |
| Zinc Borate (ZB) | 2% ~ 10% | Synergistic enhancer; imatha kuchepetsa kuphatikizika kwathunthu mukaphatikizidwa ndi AHP (zambiri zomwe zimafunikira ngati zitagwiritsidwa ntchito yokha). |
II. Kukhathamiritsa kwa Compound Ratios
- Magawo Omwe Amaphatikiza:
- AHP:ZB = 2:1 ~ 4:1(mwachitsanzo, 15% AHP + 5% ZB, okwana 20%).
- Sinthani ma ratios moyesera, mwachitsanzo:
- Kufunika kochedwa kwambiri kwa moto:AHP 15% ~ 20%, ZB 5% ~ 8%.
- Zolinga zakuthupi:AHP 10% ~ 15%, ZB 3% ~ 5%.
- Zotsatira za Synergistic:
- Zinc borate imathandizira kuchedwa kwa moto ndi:
- Kukhazikika kwa char (kulumikizana ndi aluminiyamu phosphate yopangidwa ndi AHP).
- Kutulutsa madzi omangika kuti atenge kutentha ndi kusungunula mpweya woyaka.
III. Njira Zotsimikizira Kuyesera
- Mayeso a Stepwise:
- Kuyesa payekha:Yang'anani koyamba AHP (5% ~ 20%) kapena ZB (5% ~ 15%) mosiyana chifukwa cha kuchepa kwamoto (UL-94, LOI) ndi ntchito zokutira (kumatira, kuuma, kukana madzi).
- Kukhathamiritsa kophatikiza:Mukasankha kuchuluka kwa AHP, onjezerani ZB (mwachitsanzo, 3% mpaka 8% pamene AHP ili 15%) ndikuwona kusintha kwa kuchedwa kwamoto ndi zotsatira zake.
- Zizindikiro Zofunika Kwambiri:
- Kuchedwa kwa moto:LOI (chandamale ≥28%), UL-94 mlingo (V-0/V-1), kuchuluka kwa utsi.
- Zakuthupi:Kupanga mafilimu, kumamatira (ASTM D3359), kukana madzi (palibe delamination pambuyo pa kumizidwa kwa 48h).
IV. Mfundo zazikuluzikulu
- Kukhazikika kwa Dispersion:
- AHP ndi hygroscopic-yowuma isanakwane kapena kugwiritsa ntchito mitundu yosinthidwa pamwamba.
- Gwiritsani ntchito ma dispersants (mwachitsanzo, BYK-190, TEGO Dispers 750W) kuti muchepetse kufanana ndikupewa kusungunuka.
- Kugwirizana kwa pH:
- Machitidwe a acrylic amadzimadzi amakhala ndi pH ya 8-9; onetsetsani AHP ndi ZB kukhalabe okhazikika (peŵani hydrolysis kapena kuwonongeka).
- Kutsata Malamulo:
- AHP iyenera kukwaniritsa zofunikira za RoHS zopanda halogen; ZB iyenera kugwiritsa ntchito magiredi otsika kwambiri achitsulo.
V. Njira Zina Kapena Zowonjezera
- Melamine Polyphosphate (MPP):Itha kupititsa patsogolo kuchedwa kwamoto ikaphatikizidwa ndi AHP (mwachitsanzo, 10% AHP + 5% MPP + 3% ZB).
- Nano Flame Retardants:Nano-grade ZB (kuwonjezera kuchepetsedwa mpaka 1% ~ 3%) kapena ma hydroxides awiri (LDH) kuti apititse patsogolo zotchinga.
VI. Ndemanga Zachidule
- Kukonzekera koyamba:AHP 10% ~ 15% + ZB 3% ~ 5% (okwana 13% ~ 20%), ndiye konzani.
- Njira yotsimikizira:Yesani zitsanzo zazing'ono za LOI ndi UL-94 pamene mukuwunika zamakina.
