Iingcebiso zoYilo lweFomuli eGxothayo yePolystyrene eNamafuthe Aphezulu (iiHIPS) engenaHalogen
Iimfuno zabathengi: IiHIPS ezithintela ilangatye kwiindawo zokugcina izixhobo zombane, amandla okuchaphazeleka ≥7 kJ/m², i-melt flow index (MFI) ≈6 g/10min, ukubumba ngenaliti.
1. Inkqubo yeFosforasi-Nitrogen Synergistic Flame-Retardant System
Ukwenziwa kwe-HIPS Flame-Retardant Formulation (Itheyibhile 1)
| Icandelo | Iyalayisha (phr) | Amagqabaza |
| I-resin ye-Hips | 100 | Izinto ezisisiseko |
| I-Ammonium polyphosphate (APP) | 15-20 | Umthombo wePhosphorus |
| I-Melamine cyanurate (MCA) | 5-10 | Umthombo weNitrogen, uhambelana ne-APP |
| Igrafayithi eyandisiweyo (EG) | 3-5 | Iphucula ukwakheka kwe-char |
| Iarhente yokulwa nokuvuza (PTFE) | 0.3-0.5 | Ithintela amathontsi anyibilikisiweyo |
| I-Compatibilizer (umz., ii-HIPS ezifakwe kwi-MAH) | 2-3 | Iphucula ukusasazeka |
Iimbonakalo:
- ImpumeleloUL94 V-0ngokwakhiwa kwe-intumescent char evela kwi-APP/MCA synergy.
- Ayina-halogen kwaye inobuhlobo nokusingqongileyo, kodwa inokunciphisa iimpawu zoomatshini; kufuneka ukwenziwa ngcono.
2. Inkqubo ye-Metal Hydroxide Flame-Retardant System
Ukwenziwa kweHIPS (Itheyibhile 2)
| Icandelo | Iyalayisha (phr) | Amagqabaza |
| I-resin ye-Hips | 100 | - |
| I-aluminium hydroxide (ATH) | 40-60 | I-retarder yomlilo ephambili |
| I-Magnesium hydroxide (MH) | 10-20 | Isebenzisana ne-ATH |
| Iarhente yokudibanisa i-Silane (umz., KH-550) | 1-2 | Iphucula ukusasazeka kwezalisa |
| I-Toughener (umz., i-SEBS) | 5-8 | Ihlawulela ukulahleka kwamandla okuchasana |
Iimbonakalo:
- Ifuna>50% yokulayishakwi-UL94 V-0, kodwa inciphisa amandla kunye nokuhamba kwempembelelo.
- Ifanelekile ukusetyenziswa kwezixhobo ezingasebenzisi msi uninzi/ezingenatyhefu ingako (umz., ezothutho ngololiwe).
3. Inkqubo ye-Phosphorus-Nitrogen Synergistic (i-Aluminium Hypophosphite + MCA)
Ukwenziwa kweeHIPS okuLungileyo
| Icandelo | Iyalayisha (phr) | Umsebenzi/Amanqaku |
| IiHIPS (umgangatho onefuthe eliphezulu, umz., PS-777) | 100 | Izinto ezisisiseko (impembelelo ≥5 kJ/m²) |
| I-aluminium hypophosphite (AHP) | 12-15 | Umthombo we-phosphorus, uzinzo lobushushu |
| I-Melamine cyanurate (MCA) | 6-8 | Umthombo weNitrogen, uhambelana ne-AHP |
| I-SEBS/SBS | 8-10 | Isithambisi esibalulekileyo sokubetha ≥7 kJ/m² |
| I-paraffin engamanzi/ioyile yesoya efakwe i-epoxidized | 1-2 | Isithambisi, siphucula ukuhamba/ukusasazeka |
| I-PTFE | 0.3-0.5 | Iarhente yokulwa nokuvuza |
| I-Antioxidant 1010 | 0.2 | Ithintela ukuwohloka |
Izinto eziphambili ekufuneka uziqwalasele kuYilo:
- Ukukhethwa kweResin:
- Sebenzisa amanqanaba e-HIPS anamandla aphezulu (umz.,I-Chimei PH-888,I-Taifa PG-33) enamandla okuchukumisa angaphakathi angama-5–6 kJ/m². I-SEBS iphucula ngakumbi ukuqina.
- Ulawulo lokuhamba kwamanzi:
- I-AHP/MCA inciphisa i-MFI; ibuyisela izinto zokuthambisa (umz., iparafini engamanzi) okanye iiplastiki (umz., ioyile yesoya efakwe i-epoxidized).
- Ukuba i-MFI ihlala iphantsi, yongezaI-TPU ye-2–3 phrukuphucula ukuhamba kwamanzi kunye nokuqina kwawo.
- Ukuqinisekiswa kokuBuyiselwa kweLanga:
- I-AHP ingancitshiswa ibeIiphr ezili-12ukuba zidityaniswe ne2–3 i-EGukugcina i-UL94 V-0.
- NgokubaUL94 V-2, nciphisa umthwalo othintela ilangatye ukuze ubeke phambili impembelelo/ukuhamba kwamanzi.
- Iiparameter zokuBumba ngeNjovo:
- Ubushushu:180–220°C(thintela ukonakala kwe-AHP/HIPS).
- Isantya sokujova:Phakathi-phezuluukuthintela ukuzaliswa okungaphelelanga.
Ukusebenza Okulindelekileyo:
| Ipropati | Ixabiso Elijoliswe Kulo | Umgangatho woVavanyo |
| Amandla empembelelo | ≥7 kJ/m² | I-ISO 179/1eA |
| I-MFI (200°C/5 kg) | 5–7 g/10 min | I-ASTM D1238 |
| Ukulibaziseka kwelangatye | UL94 V-0 (1.6 mm) | UL94 |
| Tensile strength | ≥25 MPa | I-ISO 527 |
4. Izisombululo ezizezinye
- Ukhetho Olunobuzaza Ngeendleko: Buyisela i-AHP ngokuyinxenye ngei-phosphorus ebomvu efakwe kancinci (3–5 phr), kodwa qaphela umda wombala (obomvu-mdaka).
- Ukuqinisekiswa: Yenza uvavanyo oluncinci ukuze ulinganisele impembelelo xa kuthelekiswa nokungavuthi komlilo ngaphambi kokuba wenze ngcono ukuhamba kwamanzi.
