PP V2 Flame Retardant Masterbatch Reference Uqulunqo
Ukufezekisa i-UL94 V2 i-flame retardancy kwi-PP (polypropylene) masterbatches, indibaniselwano ye-synergistic ye-flame retardants iyafuneka ngelixa kugcinwa ukusebenza kokusebenza kunye neempawu zoomatshini. Apha ngezantsi kukho isindululo soqulunqo olulungiselelweyo kunye neengcaciso:
I. ISindululo sokuqulunqa iSiseko
Ulwakhiwo lweNkangala yomlilo:
| Icandelo | Iyalayisha (wt%) | Inkcazo yomsebenzi |
| PP Resin | 50-60% | I-resin ye-Carrier (cebisa i-high melt flow index grade, umzekelo, i-MFI 20-30 g / 10min) |
| I-Aluminiyam Hypophosphite | 15-20% | Umthombo we-Acid, ukhuthaza ukubunjwa kwe-char, ukuzinza okuhle kwe-thermal ukwenzela ukuqhutyelwa kwePP |
| Zinc Borate | 5-8% | I-Synergistic retadant yedangatya, icinezela umsi kwaye yongeza ukuncipha komlilo kwisigaba segesi |
| Umphezulu-Modified Aluminiyam Hydroxide | 10-15% | Ukubola kwe-endothermic, yehlisa ubushushu bokutsha (unyango lomphezulu, umzekelo, i-agent edibanisa i-silane, iyacetyiswa) |
| I-Dipentaerythritol (Di-PE) | 5-8% | Umthombo weCarbon, udibanisa kunye nomthombo we-asidi ukwenza i-intumescent char |
| I-Melamine Polyphosphate (MPP) | 3-5% | Umthombo wegesi (i-supplement ecetyiswayo), ikhupha iigesi ezingenayo ukunyusa intumescence |
| Iarhente yokuchasana nokuthontsiza (PTFE) | 0.3-0.5% | Yehlisa inyibilika ukuvuza (ukhetho lwe-V2, njengoko ukuthontsiza kuvunyelwe) |
| I-Antioxidant (1010/168) | 0.3-0.5% | Ikhusela ukuthotywa kwe-thermal oxidative ngexesha lokucubungula |
| ILubricant (Zinc Stearate) | 0.5-1% | Ukuphucula ukuqhubekeka nokusasazeka |
| Isithwali soMbala & nePigment | Njengoko kufuneka | Khetha ii-pigments ezikwaziyo ukumelana nobushushu obuphezulu ukunqanda ukusabela kunye neeretardants zomlilo |
II. Amanqaku angundoqo oPhuculo
- I-Synergistic Flame Retardant System
- I-Intumescent Flame Retardant (IFR):I-Aluminium hypophosphite (umthombo we-asidi) + I-Di-PE (umthombo wekhabhoni) + i-MPP (umthombo wegesi) yenza inkqubo ye-IFR, idala i-insulating char layer ukuvimba ukushisa kunye ne-oksijini.
- I-Zinc Borate Synergy:Iphendula kunye ne-aluminiyam hypophosphite yenze umaleko okhuselayo oyiglasi, uphucula ukubuyiswa komlilo wesigaba segesi.
- IAluminiyam eHydroxide eLungisiweyo:Ukunyangwa komphezulu kunciphisa ukukhutshwa kokufuma ngexesha lokulungiswa ngelixa ubonelela ngokubola kwe-endothermic ukuthoba ubushushu bokutsha.
- Ukuqhubela phambili kunye neNdlela yokuSebenza
- Iyonke into yokulayishwa kwedangatye kufuneka ilawulwe35-45%ukuphepha ilahleko enkulu yepropathi yoomatshini.
- Sebenzisahigh-MFI PP resin (umzekelo, PPH-Y40)ukuphucula ukusasazwa kwe-masterbatch kunye nokunciphisa i-viscosity.
- Iingcebiso zoVavanyo kunye nokuQinisekisa
- Uvavanyo lokutshisa okuthe nkqo kwe-UL94:Qinisekisa ukuba amadangatye ayazicima ngaphakathi60 imizuzwanaemva kokutshiswa kabini.
- Uvavanyo loomatshini:Gxininisa kumandla okuqina (≥20 MPa) kunye namandla empembelelo (≥4 kJ/m²).
- Uzinzo lweThermal (TGA):Qinisekisa amadangatye okubola okurhoxisa amaqondo obushushu ahambelana noluhlu lokusetyenzwa kwePP (180–220°C).
III. Uhlengahlengiso Oluzikhethelayo
- UKuba Retadancy ePhezulu (umzekelo, V0):
- Yandisa i-aluminiyam hypophosphite ukuya25%, yongezaI-2% ye-silicone(ukunciphisa umsi), kwaye uphakamise i-PTFE ukuya0.8%.
- Izicelo ezingakhathali kwiindleko:
- Ukunciphisa umxholo we-MPP kwaye ukhulise ngokulinganayo i-aluminium hydroxide (ukuqinisekisa ukuzinza kokucubungula).
IV. Iingqwalasela ezingundoqo
- Imveliso ye-Masterbatch:Ukuxuba kwangaphambili ii-retardants zomlilo kunye ne-carrier resin;i-twin-screw extrusion (180–210°C)kuyacetyiswa.
- Ukomisa iAluminiyam Hydroxide:Yoma aphaI-110 ° C kwiiyure ze-4ukuthintela amaqamza ngexesha lokucubungula.
- I-Di-PE/Aluminiyam yeHypophosphite Ratiyo:Gcina1:2 ukusa kwese-1:3ukwenza i-char isebenze ngokufanelekileyo.
Ngale ndlela yolwakhiwo lulungelelanisiweyo kunye nokusetyenzwa,I-UL94 V2 idangatye lokulibazisekainokufezekiswa ngokuqhubekayo ngelixa igcina ukusebenza kokusetyenzwa kunye nokuzinza kombala. Ulingo oluncinci luyacetyiswa ukuba lulungiswe kakuhle ngokusekelwe kwiziphumo zovavanyo.
