PP V2 ina Retardant Masterbatch Reference agbekalẹ
Lati ṣaṣeyọri idaduro ina UL94 V2 ni PP (polypropylene) masterbatches, apapo amuṣiṣẹpọ ti awọn retardants ina ni a nilo lakoko mimu iṣẹ ṣiṣe ati awọn ohun-ini ẹrọ. Ni isalẹ ni iṣeduro agbekalẹ iṣapeye pẹlu awọn alaye:
I. Iṣeduro agbekalẹ ipilẹ
Ilana Idaduro Ina:
| Ẹya ara ẹrọ | Nkojọpọ (wt%) | Apejuwe iṣẹ |
| PP Resini | 50-60% | Resini ti ngbe (ṣeduro iwọn itọka ṣiṣan yo ti o ga, fun apẹẹrẹ, MFI 20-30 g/10min) |
| Aluminiomu Hypophosphite | 15-20% | Orisun Acid, ṣe agbega iṣelọpọ eedu, iduroṣinṣin igbona ti o dara fun sisẹ PP |
| Sinkii Borate | 5-8% | Idaduro ina amuṣiṣẹpọ, dinku ẹfin ati imudara idaduro ina-fase gaasi |
| Dada-Títúnṣe Aluminiomu Hydroxide | 10-15% | Jijẹ endothermic, n dinku iwọn otutu ijona (itọju oju, fun apẹẹrẹ, aṣoju asopọ silane, niyanju) |
| Dipentaerythritol (Di-PE) | 5-8% | Orisun erogba, ṣe amuṣiṣẹpọ pẹlu orisun acid lati ṣe eedu intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Orisun gaasi (afikun ti a ṣeduro), tu awọn gaasi inert silẹ lati jẹki intumescence |
| Aṣojú Anti-Dripping (PTFE) | 0.3-0.5% | Din jijo yo (aṣayan fun V2, bi a ti gba laaye sisẹ) |
| Antioxidant (1010/168) | 0.3-0.5% | Ṣe idilọwọ ibajẹ oxidative gbona lakoko sisẹ |
| Olomi (Zinc Stearate) | 0.5-1% | Imudarasi processing flowability ati pipinka |
| Awọ ti ngbe & Pigmenti | Bi o ṣe nilo | Yan awọn pigmenti sooro iwọn otutu lati yago fun awọn aati pẹlu awọn idaduro ina |
II. Bọtini Iṣapeye Points
- Synergistic ina Retardant System
- Idaduro Ina Intumescent (IFR):Aluminiomu hypophosphite (orisun acid) + Di-PE (orisun erogba) + MPP (orisun gaasi) ṣe eto IFR kan, ṣiṣẹda ohun elo eefun idabobo lati dènà ooru ati atẹgun.
- Asopọmọra Zinc Borate:Reacts pẹlu aluminiomu hypophosphite lati ṣe fẹlẹfẹlẹ aabo gilasi kan, imudara idaduro ina-fase gaasi.
- Aluminiomu Hydroxide ti a ṣe atunṣe:Itọju oju oju dinku itusilẹ ọrinrin lakoko sisẹ lakoko ti o pese jijẹ endothermic si iwọn otutu ijona kekere.
- Iwontunws.funfun Processing & Performance
- Lapapọ ikojọpọ ina retardant yẹ ki o wa ni dari ni35-45%lati yago fun significant darí pipadanu ohun ini.
- LoResini PP MFI giga (fun apẹẹrẹ, PPH-Y40)lati mu masterbatch pipinka ati ki o din iki.
- Idanwo & Awọn iṣeduro Ifọwọsi
- Idanwo Sisun Inaro UL94:Rii daju pe awọn ina pa ara wọn laarin60 aayalẹhin meji ignitions.
- Idanwo ẹrọ:Fojusi lori agbara fifẹ (≥20 MPa) ati agbara ipa (≥4 kJ/m²).
- Iduroṣinṣin Ooru (TGA):Jẹrisi awọn iwọn otutu jijẹ ti ina ibaamu iwọn sisẹ PP (180-220°C).
III. Awọn atunṣe iyan
- Fun Idaduro Iná Giga (fun apẹẹrẹ, V0):
- Mu aluminiomu hypophosphite pọ si25%, fi kun2% silikoni(ipalara ẹfin), ati gbe PTFE soke si0.8%.
- Awọn ohun elo ti o ni iye owo:
- Din akoonu MPP dinku ati niwọntunwọnsi mu aluminiomu hydroxide (ṣe idaniloju iduroṣinṣin sisẹ).
IV. Awọn ero pataki
- Ṣiṣejade Masterbatch:Ṣaju iṣaju awọn idaduro ina pẹlu resini ti ngbe;extrusion-skru (180-210°C)ti wa ni niyanju.
- Gbigbe Aluminiomu Hydroxide:Gbẹ ni110 ° C fun wakati 4lati dena awọn nyoju lakoko sisẹ.
- Di-PE/Aluminiomu Hypophosphite Ratio:Ṣe itọju1:2 si 1:3fun ti aipe eedu Ibiyi ṣiṣe.
Pẹlu ilana iṣapeye yii ati ọna ṣiṣe,UL94 V2 ina idadurole ṣe aṣeyọri nigbagbogbo lakoko titọju iṣẹ ṣiṣe ati iduroṣinṣin awọ. Awọn idanwo iwọn-kekere ni a ṣe iṣeduro fun atunṣe-itanran ti o da lori awọn abajade idanwo.
