Shawarwari Tsara Tsare-Tsaren Wuta don Halogen-Free Babban Tasirin Polystyrene (HIPS)
Bukatun Abokin ciniki: HIPS mai ɗaukar wuta don gidaje na kayan lantarki, ƙarfin tasiri ≥7 kJ / m², narke kwarara index (MFI) ≈6 g / 10min, allura gyare-gyare.
1. Tsarin phosphorus-Nitrogen Synergistic Flame-Retardant System
Ƙirƙirar Harshen Harshen HIPS (Table 1)
| Bangaren | Ana lodawa (phr) | Jawabi |
| Farashin HIPS | 100 | Kayan tushe |
| Ammonium polyphosphate (APP) | 15-20 | Tushen phosphorus |
| Melamine cyanurate (MCA) | 5-10 | Tushen Nitrogen, yana aiki tare da APP |
| Fadada graphite (EG) | 3-5 | Yana haɓaka samuwar char |
| Wakilin Anti-dripping (PTFE) | 0.3-0.5 | Yana hana zub da jini |
| Mai jituwa (misali, HIPS-grafted MAH) | 2-3 | Yana inganta watsawa |
Siffofin:
- NasararSaukewa: UL94V-0ta hanyar ƙirƙirar char intumescent daga haɗin gwiwar APP/MCA.
- Halogen-free da eco-friendly, amma yana iya rage kayan aikin injiniya; ana buƙatar ingantawa.
2. Metal Hydroxide Flame-Retardant System
Tsarin HIPS (Table 2)
| Bangaren | Ana lodawa (phr) | Jawabi |
| Farashin HIPS | 100 | - |
| Aluminum hydroxide (ATH) | 40-60 | Farkon harshen wuta |
| Magnesium hydroxide (MH) | 10-20 | Yana aiki tare da ATH |
| Wakilin haɗin gwiwar Silane (misali, KH-550) | 1-2 | Yana inganta tarwatsewar filler |
| Toughener (misali, SEBS) | 5-8 | Yana ramawa ga asarar ƙarfin tasiri |
Siffofin:
- Ana bukata> 50% loadingdon UL94 V-0, amma yana lalata ƙarfin tasiri da gudana.
- Ya dace da aikace-aikacen ƙaramar hayaki/ƙananan guba (misali, hanyar jirgin ƙasa).
3. Phosphorus-Nitrogen Synergistic System (Aluminum Hypophosphite + MCA)
Ingantaccen Tsarin HIPS
| Bangaren | Ana lodawa (phr) | Aiki / Bayanan kula |
| HIPS (maki mai tasiri, misali, PS-777) | 100 | Kayan tushe (tasirin ≥5 kJ/m²) |
| Aluminum hypophosphite (AHP) | 12-15 | Tushen phosphorus, kwanciyar hankali na thermal |
| Melamine cyanurate (MCA) | 6-8 | Tushen Nitrogen, yana aiki tare da AHP |
| SEBS/SBS | 8-10 | Mahimmin ƙarfi don tasiri ≥7 kJ/m² |
| Liquid paraffin/epoxidized man waken soya | 1-2 | Man shafawa, yana inganta kwarara / watsawa |
| PTFE | 0.3-0.5 | Mai hana-dripping wakili |
| Antioxidant 1010 | 0.2 | Yana hana lalacewa |
Mabuɗin Zane-zane:
- Zaɓin guduro:
- Yi amfani da matakan HIPS masu tasiri (misali,Saukewa: PH-888,Taifa PG-33) tare da ƙarfin tasirin tasiri na 5-6 kJ/m². SEBS yana ƙara haɓaka tauri.
- Ikon Gudanarwa:
- AHP/MCA rage MFI; rama tare da man shafawa (misali, paraffin ruwa) ko robobi (misali, man waken soya mai lalacewa).
- Idan MFI ta kasance ƙasa, ƙara2-3 phr TPUdon inganta kwarara da tauri.
- Tabbatar da Ciwon Wuta:
- AHP za a iya rage zuwa12 phridan aka hada da2-3 phr EGdon kula da UL94 V-0.
- DominSaukewa: UL94V-2, Rage ɗorawa mai ɗaukar wuta don ba da fifikon tasiri / gudana.
- Ma'aunin Gyaran allura:
- Zazzabi:180-220 ° C(kauce wa lalacewar AHP/HIPS).
- Gudun allura:Matsakaici-highdon hana cikar cikawa.
Ayyukan da ake tsammani:
| Dukiya | Darajar Target | Matsayin Gwaji |
| Ƙarfin tasiri | ≥7 kJ/m² | ISO 179/1 eA |
| MFI (200°C/5kg) | 5-7 g/10 min | Saukewa: ASTM D1238 |
| Dagewar harshen wuta | UL94 V-0 (1.6 mm) | Farashin UL94 |
| Ƙarfin ƙarfi | ≥25 MPa | ISO 527 |
4. Madadin Magani
- Zaɓin Ƙirar Kuɗi: Sauya AHP wani bangare dajan phosphorus (3-5 phr), amma lura iyakance launi (ja-ja-launin ruwan kasa).
- Tabbatarwa: Gudanar da ƙananan gwaje-gwaje don daidaita tasiri vs. jinkirin harshen wuta kafin inganta kwarara.
