PP V2 Flame Retardant Masterbatch Reference Formulation
Kuti mukwaniritse UL94 V2 flame retardancy mu PP (polypropylene) masterbatches, kuphatikiza kophatikizana kwa zoletsa moto kumafunika ndikusunga magwiridwe antchito ndi makina amakina. Pansipa pali malingaliro okonzedwa bwino omwe ali ndi mafotokozedwe:
I. Malingaliro a Base Formulation
Kukonzekera kwa Flame Retardant:
| Chigawo | Kutsegula (wt%) | Kufotokozera Ntchito |
| PP Resin | 50-60% | Chonyamulira utomoni (amalangiza mkulu kusungunula flow index kalasi, mwachitsanzo, MFI 20-30 g/10min) |
| Aluminium Hypophosphite | 15-20% | Gwero la asidi, limalimbikitsa mapangidwe a char, kukhazikika kwabwino kwa kutentha kwa PP processing |
| Zinc Borate | 5-8% | Synergistic flame retardant, imachepetsa utsi ndikuwonjezera kuchedwa kwa gasi |
| Pamwamba-Zosinthidwa Aluminiyamu Hydrooxide | 10-15% | Kuwola kwa Endothermic, kumachepetsa kuyaka (mankhwala apamtunda, mwachitsanzo, silane coupling agent, akulimbikitsidwa) |
| Dipentaerythritol (Di-PE) | 5-8% | Gwero la kaboni, limalumikizana ndi gwero la asidi kuti lipange char intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Gwero la gasi (chowonjezera chovomerezeka), chimatulutsa mpweya wa inert kuti uwonjezere mphamvu |
| Anti-Dripping Agent (PTFE) | 0.3-0.5% | Amachepetsa kudontha kwa sungunuka (ngati mukufuna V2, ngati kudontha kumaloledwa) |
| Antioxidant (1010/168) | 0.3-0.5% | Imalepheretsa kuwonongeka kwa okosijeni yamafuta panthawi yokonza |
| Lubricant (Zinc Stearate) | 0.5-1% | Imakonza flowability ndi kubalalitsidwa processing |
| Mtundu Wonyamula & Pigment | Monga kufunikira | Sankhani utoto wosagwirizana ndi kutentha kwambiri kuti mupewe kuchitapo kanthu ndi zoletsa moto |
II. Mfundo Zofunika Kwambiri
- Synergistic Flame Retardant System
- Intumescent Flame Retardant (IFR):Aluminiyamu hypophosphite (gwero la asidi) + Di-PE (gwero la kaboni) + MPP (gwero la gasi) imapanga dongosolo la IFR, kupanga chiwongolero chamoto chotchinga kuti chitseke kutentha ndi mpweya.
- Zinc Borate Synergy:Imakhudzidwa ndi aluminiyamu hypophosphite kupanga wosanjikiza wagalasi woteteza, kukulitsa kuchedwa kwa gasi lawilo.
- Kusinthidwa Aluminiyamu Hydrooxide:Kuchiza pamwamba kumachepetsa kutulutsa chinyezi panthawi yokonza pomwe kumapereka kuwonongeka kwa endothermic kuti muchepetse kutentha.
- Processing & Performance Balance
- Kutsegula kwathunthu koletsa moto kuyenera kuwongoleredwa35-45%kupewa kuwonongeka kwakukulu kwa katundu wamakina.
- Gwiritsani ntchitomkulu-MFI PP utomoni (mwachitsanzo, PPH-Y40)kusintha masterbatch kubalalitsidwa ndi kuchepetsa mamasukidwe akayendedwe.
- Kuyesa & Kutsimikizira Malangizo
- UL94 Vertical Burning Test:Onetsetsani kuti moto uzizima mkati60 masekondipambuyo poyatsa ziwiri.
- Kuyesa Kwamakina:Yang'anani pa mphamvu yolimba (≥20 MPa) ndi mphamvu yamphamvu (≥4 kJ/m²).
- Thermal Stability (TGA):Tsimikizirani kutentha kowonongeka kwamoto kumafanana ndi PP processing range (180-220 ° C).
III. Zosintha Zosankha
- Pakuchedwa Kwambiri kwa Flame (mwachitsanzo, V0):
- Wonjezerani aluminium hypophosphite kuti25%, kuwonjezera2% silicone(kuletsa kusuta), ndikukweza PTFE ku0.8%.
- Mapulogalamu Otengera Mtengo:
- Chepetsani zomwe zili MPP ndikuwonjezera pang'onopang'ono aluminium hydroxide (onetsetsani kuti kukhazikika kwadongosolo).
IV. Mfundo zazikuluzikulu
- Kupanga kwa Masterbatch:Sakanizani zotsalira zamoto ndi utomoni wonyamulira;mapasa-sctrusion (180-210 ° C)akulimbikitsidwa.
- Kuyanika Aluminium Hydroxide:Yanikani pa110 ° C kwa maola 4kuteteza thovu pa processing.
- Di-PE/Aluminium Hypophosphite Ratio:Pitirizani1:2 mpaka 1:3kuti apange bwino kwambiri char.
Ndi njira yabwinoyi yopangira ndi kukonza,UL94 V2 kuchedwa kwamotozitha kukwaniritsidwa nthawi zonse ndikusunga magwiridwe antchito komanso kukhazikika kwamtundu. Mayesero ang'onoang'ono amalimbikitsidwa kuti awonedwe bwino potengera zotsatira za mayeso.
