Izincomo Zokwakhiwa Kwe-Flame-Retardant ze-Halogen-Free High-Impact Polystyrene (HIPS)
Izidingo Zekhasimende: I-HIPS ebambezela ilangabi yezindlu zikagesi, amandla okuthinta ≥7 kJ/m², inkomba yokuncibilika kokuncibilika (MFI) ≈6 g/10min, ukubumba umjovo.
1. Uhlelo Lwe-Phosphorus-Nitrogen Synergistic-Retardant Flame
Ukwakhiwa Kwe-HIPS Flame-Retardant (Ithebula 1)
| Isakhi | Iyalayisha (phr) | Ukuphawula |
| I-HIPS resin | 100 | Izinto eziyisisekelo |
| I-Ammonium polyphosphate (APP) | 15-20 | Umthombo we-phosphorus |
| I-Melamine cyanrate (MCA) | 5-10 | Umthombo nitrogen, synergizes nge APP |
| I-graphite enwetshiwe (EG) | 3-5 | Ithuthukisa ukwakheka kwezinhlamvu |
| I-Anti-dripping agent (PTFE) | 0.3-0.5 | Ivimbela amaconsi ancibilikisiwe |
| I-Compatibilizer (isb, i-MAH-grafted HIPS) | 2-3 | Ithuthukisa ukuhlakazeka |
Izici:
- UyaphumelelaI-UL94 V-0ngokusebenzisa i-intumescent char formation evela ku-APP/MCA synergy.
- I-halogen-free kanye ne-eco-friendly, kodwa ingase inciphise izakhiwo zemishini; ukulungiselelwa kuyadingeka.
2. Isistimu ye-Metal Hydroxide Flame-Retardant
Ukwakhiwa Kwe-HIPS (Ithebula 2)
| Isakhi | Iyalayisha (phr) | Ukuphawula |
| I-HIPS resin | 100 | - |
| I-Aluminium hydroxide (ATH) | 40-60 | I-retardant yokuqala yomlilo |
| I-Magnesium hydroxide (MH) | 10-20 | Isebenzisana ne-ATH |
| I-ejenti yokuhlanganisa ye-Silane (isb, KH-550) | 1-2 | Ithuthukisa ukusabalalisa kwe-filler |
| I-Toughener (isb, i-SEBS) | 5-8 | Inxephezela ukulahleka kwamandla okuthinta |
Izici:
- Idinga>50% iyalayishaye-UL94 V-0, kodwa yehlisa amandla okuthinta nokugeleza.
- Ifanele izinhlelo zokusebenza ezinentuthu ephansi/ ezinobuthi obuphansi (isb., ezokuthutha ngololiwe).
3. I-Phosphorus-Nitrogen Synergistic System (Aluminium Hypophosphite + MCA)
Ukwakhiwa Kwe-HIPS Okulungiselelwe
| Isakhi | Iyalayisha (phr) | Umsebenzi/Amanothi |
| I-HIPS (ibanga elinomthelela ophezulu, isb, PS-777) | 100 | Izinto eziyisisekelo (umthelela ≥5 kJ/m²) |
| I-Aluminium hypophosphite (AHP) | 12-15 | Umthombo we-Phosphorus, ukuzinza kokushisa |
| I-Melamine cyanrate (MCA) | 6-8 | Umthombo we-nitrogen, uhlangana ne-AHP |
| SEBS/SBS | 8-10 | I-toughener ebalulekile yomthelela ≥7 kJ/m² |
| Upharafini owuketshezi/amafutha kabhontshisi wesoya epoxidized | 1-2 | I-Lubricant, ithuthukisa ukugeleza/ukuhlakazeka |
| I-PTFE | 0.3-0.5 | I-Anti-dripping ejenti |
| I-Antioxidant 1010 | 0.2 | Ivimbela ukuwohloka |
Okucatshangelwayo Okubalulekile Kwedizayini:
- Ukukhetha Resin:
- Sebenzisa amamaki e-HIPS anethonya eliphezulu (isb.I-Chimei PH-888,Isizwe PG-33) ngamandla omthelela wemvelo angu-5–6 kJ/m². I-SEBS ithuthukisa futhi ukuqina.
- Ukulawula Ukugeleza:
- I-AHP/MCA yehlisa i-MFI; nxephezela ngezinto zokugcoba (isb., upharafini owuketshezi) noma amapulasitiki (isb., uwoyela kabhontshisi wesoya epoxidized).
- Uma i-MFI ihlala iphansi, engeza2–3 phr TPUukuthuthukisa ukugeleza nokuqina.
- Ukuqinisekiswa Kwe-Flame Retardancy:
- I-AHP ingancishiswa ibe12 umquma kuhlangene2-3 imizuzwana EGukugcina i-UL94 V-0.
- NgobaI-UL94 V-2, nciphisa ukulayishwa kwelangabi ukuze ubeke phambili umthelela/ukugeleza.
- Amapharamitha wokubumba wokujova:
- Izinga lokushisa:180–220°C(gwema ukucekelwa phansi kwe-AHP/HIPS).
- Isivinini sokujova:Ukuphakama okuphakathiukuvimbela ukugcwaliswa okungaphelele.
Ukusebenza Okulindelekile:
| Impahla | Inani eliqondiwe | Izinga Lokuhlola |
| Amandla okuthinta | ≥7 kJ/m² | ISO 179/1eA |
| I-MFI (200°C/5 kg) | 5–7 g/10min | I-ASTM D1238 |
| Ukuncipha komlilo | I-UL94 V-0 (1.6 mm) | UL94 |
| Amandla aqinile | ≥25 MPa | ISO 527 |
4. Ezinye Izixazululo
- Inketho Ezwela Izindleko: Faka esikhundleni i-AHP kancanei-microencapsulated red phosphorus (3–5 phr), kodwa phawula ukulinganiselwa kombala (okubomvu-nsundu).
- Ukuqinisekisa: Yenza izivivinyo ezincane ukuze ulinganise umthelela ngokumelene nokuncipha kwelangabi ngaphambi kokuthuthukisa ukugeleza.
