Malangizo Opangira Mapangidwe Osasinthika a Flame-Retardant a Halogen-Free High-Impact Polystyrene (HIPS)
Zofuna Makasitomala: HIPS yoletsa moto panyumba za zida zamagetsi, mphamvu yamphamvu ≥7 kJ/m², melt flow index (MFI) ≈6 g/10min, kuumba jekeseni.
1. Phosphorus-Nitrogen Synergistic Flame-Retardant System
Mapangidwe Oletsa Moto a HIPS (Table 1)
| Chigawo | Kutsegula (phr) | Ndemanga |
| HIPS utomoni | 100 | Zida zoyambira |
| Ammonium polyphosphate (APP) | 15-20 | Phosphorous source |
| Melamine cyanrate (MCA) | 5-10 | Gwero la nayitrogeni, limalumikizana ndi APP |
| graphite yowonjezera (EG) | 3-5 | Imawonjezera mapangidwe a char |
| Anti-dripping agent (PTFE) | 0.3-0.5 | Imateteza madontho osungunuka |
| Compatibilizer (mwachitsanzo, MAH-yolumikizidwa HIPS) | 2-3 | Kupititsa patsogolo kubalalitsidwa |
Mawonekedwe:
- AmakwaniritsaUL94 V-0kudzera pakupanga kwachar kuchokera ku APP/MCA synergy.
- Halogen-free ndi eco-friendly, koma akhoza kuchepetsa makina katundu; kukhathamiritsa chofunika.
2. Metal Hydroxide Flame-Retardant System
Kupanga kwa HIPS (Table 2)
| Chigawo | Kutsegula (phr) | Ndemanga |
| HIPS utomoni | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Choyambitsa choyambitsa moto |
| Magnesium hydroxide (MH) | 10-20 | Zogwirizana ndi ATH |
| Silane coupling agent (mwachitsanzo, KH-550) | 1-2 | Kupititsa patsogolo kubalana kwa filler |
| Toughener (mwachitsanzo, SEBS) | 5-8 | Imalipiritsa kutayika kwa mphamvu |
Mawonekedwe:
- Zimafunika>50% kutsitsakwa UL94 V-0, koma kumawononga mphamvu ndi kuyenda.
- Zoyenera kugwiritsa ntchito utsi wochepa/opanda poizoni (monga mayendedwe apanjanji).
3. Phosphorus-Nitrogen Synergistic System (Aluminium Hypophosphite + MCA)
Kusintha kwa HIPS
| Chigawo | Kutsegula (phr) | Ntchito/Zolemba |
| HIPS (giredi yamphamvu kwambiri, mwachitsanzo, PS-777) | 100 | Zida zoyambira (zokhudza ≥5 kJ/m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Phosphorous gwero, matenthedwe bata |
| Melamine cyanrate (MCA) | 6-8 | Gwero la nayitrogeni, limalumikizana ndi AHP |
| SEBS / SBS | 8-10 | Chothandizira kwambiri chothandizira ≥7 kJ/m² |
| Mafuta a parafini / epoxidized soya mafuta | 1-2 | Mafuta, amathandizira kuyenda bwino / kubalalitsidwa |
| PTFE | 0.3-0.5 | Anti-dripping agent |
| Antioxidant 1010 | 0.2 | Zimalepheretsa kunyozeka |
Zolinga Zofunika Kwambiri:
- Kusankhidwa kwa Resin:
- Gwiritsani ntchito magiredi apamwamba a HIP (mwachitsanzo,Chimei PH-888,Dziko PG-33) yokhala ndi mphamvu yachilengedwe ya 5–6 kJ/m². SEBS imawonjezera kulimba.
- Flowability Control:
- AHP / MCA kuchepetsa MFI; perekani ndi mafuta odzola (mwachitsanzo, parafini wamadzimadzi) kapena zopangira pulasitiki (mwachitsanzo, mafuta a soya a epoxidized).
- Ngati MFI ikhalabe yotsika, onjezani2-3 mphindi TPUkupititsa patsogolo kuyenda ndi kulimba.
- Kutsimikizika kwa Flame Retardancy:
- AHP ikhoza kuchepetsedwa kukhala12 phngati kugwirizana ndi2-3 mphindi EGkusunga UL94 V-0.
- ZaUL94 V-2, chepetsani kulongedza koletsa moto kuti muyike patsogolo kukhudzidwa / kuyenda.
- Injection Molding Parameters:
- Kutentha:180-220 ° C(peŵani kuwonongeka kwa AHP/HIPS).
- Kuthamanga kwa jekeseni:Wapakati-mmwambakuteteza kudzaza kosakwanira.
Zomwe Tikuyembekezera:
| Katundu | Mtengo Wapatsogolo | Test Standard |
| Mphamvu yamphamvu | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5kg) | 5-7 g / 10 min | Chithunzi cha ASTM D1238 |
| Kuchedwa kwamoto | UL94 V-0 (1.6 mm) | UL94 |
| Kulimba kwamakokedwe | ≥25 MPa | ISO 527 |
4. Njira Zothetsera
- Njira Yopanda Mtengo: Sinthani AHP pang'ono ndiphosphorous wofiira wa microencapsulated (3-5 phr), koma zindikirani malire amtundu (wofiira-bulauni).
- Kutsimikizira: Chitani mayesero ang'onoang'ono kuti athetseretu kuwonongeka kwa flame retardancy musanakonzekere kuyenda bwino.
