Izindululo zoYilo lwe-Flame-Retardant kuYilo lwe-Halogen-Free-High-Impact High-Impact Polystyrene (HIPS)
Iimfuno zoMthengi: I-HIPS engadangayo kwizindlu zezixhobo zombane, amandla empembelelo ≥7 kJ/m², isalathisi sokunyibilika kokunyibilika (MFI) ≈6 g/10min, ukubumba inaliti.
1. Inkqubo ye-Phosphorus-Nitrogen Synergistic Flame-Retardant
I-HIPS Ulwakhiwo olungagungqiyo kwidangatye (Itheyibhile 1)
| Icandelo | Iyalayisha (phr) | Amagqabantshintshi |
| I-HIPS resin | 100 | Izinto ezisisiseko |
| I-Ammonium polyphosphate (APP) | 15-20 | Umthombo wePhosphorus |
| I-Melamine cyanrate (MCA) | 5-10 | Umthombo we-nitrogen, udibanisa ne-APP |
| igraphite eyandisiweyo (EG) | 3-5 | Yandisa ukwakheka kwe char |
| Iarhente yokuchasa ukuvuza (PTFE) | 0.3-0.5 | Ikhusela amathontsi atyhidiweyo |
| Isingqineli (umzekelo, iHIPS ehlonyelwe kwi-MAH) | 2-3 | Ukuphucula ukusasazwa |
Iimbonakalo:
- IyaphumelelaUL94 V-0ngokwenziwa kwe-intumescent char evela kwi-APP/MCA synergy.
- I-halogen-free kunye ne-eco-friendly, kodwa inokunciphisa iimpawu zoomatshini; ulungiselelo olufunekayo.
2. Inkqubo yeMetal Hydroxide Flame-Retardant
Ukuqulunqwa kwe-HIPS (Itheyibhile 2)
| Icandelo | Iyalayisha (phr) | Amagqabantshintshi |
| I-HIPS resin | 100 | - |
| Ialuminiyam hydroxide (ATH) | 40-60 | Isithinteli sokuqala somlilo |
| I-Magnesium hydroxide (MH) | 10-20 | Isebenzisana ne-ATH |
| Silane coupling agent (umzekelo, KH-550) | 1-2 | Ukuphucula ukusasazwa kwefayili |
| I-Toughener (umzekelo, i-SEBS) | 5-8 | Ihlawulela ilahleko yamandla empembelelo |
Iimbonakalo:
- Ifuna>50% iyalayishaye-UL94 V-0, kodwa ithoba amandla empembelelo kunye nokuhamba.
- Ilungele ukusetyenziswa komsi ophantsi/ubutyhefu obuphantsi (umzekelo, umzila kaloliwe).
3. I-Phosphorus-Nitrogen Synergistic System (iAluminiyam Hypophosphite + MCA)
Uqulunqo lwe-HIPS olulungiselelweyo
| Icandelo | Iyalayisha (phr) | Umsebenzi/Amanqaku |
| I-HIPS (ibakala elinempembelelo ephezulu, umzekelo, i-PS-777) | 100 | Izinto ezisisiseko (impembelelo ≥5 kJ/m²) |
| I-Aluminiyam hypophosphite (AHP) | 12-15 | Umthombo wePhosphorus, ukuzinza kwe-thermal |
| I-Melamine cyanrate (MCA) | 6-8 | Umthombo we-nitrogen, udibanisa ne-AHP |
| SEBS/SBS | 8-10 | I-Critical toughener yempembelelo ≥7 kJ/m² |
| Iparafini elulwelo/ioyile yeembotyi zesoya epoxidized | 1-2 | I-Lubricant, iphucula ukuhamba / ukusasazwa |
| PTFE | 0.3-0.5 | Iarhente yokuchasa ukuvuza |
| I-Antioxidant 1010 | 0.2 | Ithintela ukuthotywa |
Iingqwalasela ezingundoqo zoYilo:
- Ukukhethwa kweResin:
- Sebenzisa amabanga eHIPS anefuthe eliphezulu (umz.,Chimei PH-888,ISizwe PG-33) ngamandla empembelelo yendalo eyi-5–6 kJ/m². I-SEBS iphinda yongeze ubunzima.
- Ulawulo lokuqukuqela:
- I-AHP/MCA inciphisa i-MFI; Buyekeza ngezithambiso (umzekelo, iparafini elulwelo) okanye iiplastiki (umzekelo, i-oyile yeembotyi zesoya epoxidized).
- Ukuba i-MFI ihlala iphantsi, yongeza2–3 phr TPUukuphucula ukuhamba kunye nokuqina.
- Ukuqinisekiswa kokuBuyiswa koMbane:
- I-AHP inokuncitshiswa ibe12 phrukuba idibene ne2–3 phr EGukugcina UL94 V-0.
- KubaUL94 V-2, ukunciphisa ukulayishwa kwedangatye ukubeka phambili impembelelo / ukuhamba.
- Isitofu sokubumba iParameters:
- Ubushushu:180–220°C(ukuphepha ukuthotywa kwe-AHP/HIPS).
- Isantya sokutofa:Phakathi-phezuluukuthintela ukuzaliswa okungaphelelanga.
Umsebenzi olindelekileyo:
| Ipropati | Ixabiso ekujoliswe kulo | Umgangatho woVavanyo |
| Amandla empembelelo | ≥7 kJ/m² | ISO 179/1eA |
| I-MFI (200°C/5 kg) | 5–7 g/10min | I-ASTM D1238 |
| Ukusilela komlilo | UL94 V-0 (1.6 mm) | UL94 |
| Tensile strength | ≥25 MPa | ISO 527 |
4. Ezizezinye Izisombululo
- Indleko-enovakalelo ukhetho: Faka endaweni ye-AHP ngokuyinxenyei-microencapsulated phosphorus ebomvu (3–5 phr), kodwa qaphela umda wombala (obomvu-brown).
- Ukuqinisekiswa: Qhuba ulingo oluncinci ukulinganisa impembelelo vs. Ukwehla komlilo phambi kokuphucula ukuhamba.
