I-PP V2 Flame Retardant Masterbatch Reference Formulation
Ukuze kufezekiswe ukuthintela ilangatye le-UL94 V2 kwi-PP (polypropylene) masterbatches, kufuneka indibaniselwano ye-synergistic ye-flame retardants ngelixa kugcinwa ukusebenza kakuhle kunye neempawu zoomatshini. Apha ngezantsi kukho isindululo se-formulation esilungiselelwe kakuhle kunye neenkcazo:
I. Ingcebiso yoKwakha okuSeseko
Ukwenziwa kweFlame Retardant:
| Icandelo | Ukulayisha (ubunzima%) | Inkcazo yomsebenzi |
| I-PP Resin | 50-60% | I-resin yokuthwala (cebisa i-high melt flow index grade, umz., i-MFI 20-30 g/10min) |
| I-Aluminium Hypophosphite | 15-20% | Umthombo we-asidi, ukhuthaza ukwakheka kwe-char, uzinzo oluhle lobushushu kwi-PP processing |
| I-Zinc Borate | 5-8% | Ithintela ilangatye ngendlela efanayo, ithintela umsi kwaye yonyusa ukuthintela ilangatye ngegesi |
| I-Aluminium Hydroxide eguqulweyo kumphezulu | 10-15% | Ukubola kwe-endothermic, kunciphisa ubushushu bokutsha (unyango lomphezulu, umz., i-silane coupling agent, iyacetyiswa) |
| I-Dipentaerythritol (i-Di-PE) | 5-8% | Umthombo wekhabhoni, uhambelana nomthombo we-asidi ukwenza i-intumescent char |
| I-Melamine Polyphosphate (MPP) | 3-5% | Umthombo wegesi (isongezo esicetyiswayo), ukhupha iigesi ezingasebenziyo ukuze kuphuculwe ukudumba |
| Iarhente Yokuchasa Ukuvuza (i-PTFE) | 0.3-0.5% | Inciphisa ukuthontsiza okunyibilikayo (ukhetho kwi-V2, njengoko ukuthontsiza kuvumelekile) |
| I-Antioxidant (1010/168) | 0.3-0.5% | Ithintela ukubola kwe-oxidative yobushushu ngexesha lokucubungula |
| Isithambisi (iZinc Stearate) | 0.5-1% | Iphucula ukuhamba kakuhle kokucubungula kunye nokusasazeka |
| Umthwali wombala kunye nePigment | Njengoko kufuneka | Khetha imibala ekwaziyo ukumelana nobushushu obuphezulu ukuze uphephe ukusabela kwizinto ezithintela ilangatye |
II. Amanqaku Okuphucula Amanqaku Aphambili
- Inkqubo yokuBuyisela ilangatye ehambelanayo
- I-Intumescent Flame Retardant (IFR):I-aluminium hypophosphite (umthombo we-asidi) + i-Di-PE (umthombo wekhabhoni) + i-MPP (umthombo wegesi) zenza inkqubo ye-IFR, zenze umaleko we-char okhusela ubushushu kunye ne-oxygen.
- Intsebenziswano yeZinc Borate:Iphendula kunye ne-aluminium hypophosphite ukuze yenze umaleko okhuselayo ofana neglasi, onyusa ukungakwazi komlilo ukubamba igesi.
- I-Aluminium Hydroxide eguquliweyo:Unyango lomphezulu lunciphisa ukukhululwa komswakama ngexesha lokucubungula ngelixa lubonelela ngokubola kwe-endothermic ukuze kuncitshiswe ubushushu bokutsha.
- Ibhalansi yokucubungula kunye nokusebenza
- Umthwalo opheleleyo othintela ilangatye kufuneka ulawulwe kwi35-45%ukuze kuthintelwe ukulahleka okukhulu kwepropathi yoomatshini.
- Sebenzisai-resin ye-PP ene-MFI ephezulu (umz., i-PPH-Y40)ukuphucula ukusasazeka kwe-masterbatch kunye nokunciphisa i-viscosity.
- Iingcebiso zoVavanyo kunye noQinisekiso
- Uvavanyo lokutsha oluthe nkqo lwe-UL94:Qinisekisa ukuba amalangatye ayazicima ngokwawo ngaphakathiImizuzwana engama-60emva kokutshiswa kabini.
- Uvavanyo lweMishini:Gxila kumandla okutyhafa (≥20 MPakunye namandla empembelelo (≥4 kJ/m²).
- Uzinzo lobushushu (TGA):Qinisekisa ukuba amaqondo obushushu okubola agcina ilangatye ahambelana noluhlu lokucubungula lwe-PP (180–220°C).
III. Uhlengahlengiso oluKhethekileyo
- Kwi-Higher Flame Retardancy (umz., V0):
- Yandisa i-aluminium hypophosphite ibe25%, yongezai-silicone eyi-2%(ukunciphisa umsi), kwaye unyuse i-PTFE iye kwi0.8%.
- Izicelo Ezinobuzaza Ngeendleko:
- Nciphisa umxholo we-MPP kwaye wonyuse i-aluminium hydroxide ngokulinganisela (qinisekisa uzinzo ekucutshungulweni kwayo).
IV. Izinto ezibalulekileyo ekufuneka ziqwalaselwe
- Imveliso yeMasterbatch:Xuba izinto ezithintela ilangatye kwangaphambili kunye ne-carrier resin;ukukhupha izikrufu ezimbini (180–210°C)kuyacetyiswa.
- Ukomisa i-Aluminium Hydroxide:Yomisa e110°C iiyure ezi-4ukuthintela amaqamza ngexesha lokucubungula.
- I-Di-PE/Aluminiyam yeHypophosphite Ratiyo:Gcina1:2 ukuya ku-1:3ukuze kubekho ukusebenza kakuhle kokwakhiwa kwe-char.
Ngale ndlela yokwenza nokucubungula ephuculiweyo,I-UL94 V2 iyalibazisa ilangatyeinokufezekiswa rhoqo ngelixa kugcinwa ukusebenza kokucubungula kunye nozinzo lombala. Kucetyiswa uvavanyo oluncinci ukuze kulungiswe kakuhle ngokusekelwe kwiziphumo zovavanyo.
