Nga Taunakitanga Hoahoa Whakatairanga Whakamutunga mo te Halogen-Free High-Impact Polystyrene (HIPS)
Nga Whakaritenga Kaihoko: HIPS mura-muri mo nga whare taputapu hiko, te kaha o te paanga ≥7 kJ/m², te taurangi rere rewa (MFI) ≈6 g/10min, te whakarewa i te werohanga.
1. Phosphorus-Nitrogen Synergistic Flame-Retardant Pūnaha
HIPS Hanganga-a-Rama (Ripanga 1)
| Waehanga | Uta ana (phr) | Nga korero |
| HIPS kapia | 100 | Mahinga turanga |
| Amonium polyphosphate (APP) | 15-20 | Puna Phosphorus |
| Melamine cyanurate (MCA) | 5-10 | Te puna hauota, ka hono tahi me te APP |
| Kauwhata roha (EG) | 3-5 | Whakarei ake te hanga tohu |
| He kaihoko parepare (PTFE) | 0.3-0.5 | Ka aukati i nga rūrūtia rewa |
| Hototahi (hei tauira, HIPS kua honoa-MAH) | 2-3 | Ka pai ake te marara |
Ngā āhuatanga:
- Ka tutukiUL94 V-0na roto i te hanga o te waro mai i te APP/MCA.
- Kore-kore me te pai-taiao, engari ka whakaiti pea i nga taonga miihini; e hiahiatia ana te arotautanga.
2. Pūnaha Whakahau-a-Rama-Rangi Hangarau Hangarau
Hanganga HIPS (Ripanga 2)
| Waehanga | Uta ana (phr) | Nga korero |
| HIPS kapia | 100 | - |
| Konumohe waihā (ATH) | 40-60 | Te mura mura tuatahi |
| Konupora waihā (MH) | 10-20 | Ka hono tahi me ATH |
| He kaihoko honoa Silane (hei tauira, KH-550) | 1-2 | Ka whakapai ake i te whakamararatanga whakakii |
| Kaikaha (hei tauira, SEBS) | 5-8 | Ka utua mo te ngaronga kaha o te paanga |
Ngā āhuatanga:
- E hiahia ana>50% te utamo UL94 V-0, engari ka whakaheke i te kaha me te rere.
- E tika ana mo nga tono auahi-iti/iti-paitini (hei tauira, te whakawhiti tereina).
3. Phosphorus-Nitrogen Synergistic System (Aluminium Hypophosphite + MCA)
Whakaritenga HIPS kua pai ake
| Waehanga | Uta ana (phr) | Mahi/Tuhipoka |
| HIPS (koeke paanga-nui, hei tauira, PS-777) | 100 | Rauemi turanga (paanga ≥5 kJ/m²) |
| Konumohe hypophosphite (AHP) | 12-15 | Pūtake Phosphorus, pūmautanga waiariki |
| Melamine cyanurate (MCA) | 6-8 | Te puna hauota, ka hono tahi me te AHP |
| SEBS/SBS | 8-10 | Te whakakaha tino nui mo te paanga ≥7 kJ/m² |
| Te paraffin wai/hinu soypi kua whakapourihia | 1-2 | Whakahinuhinu, whakapai ake i te rere/marara |
| PTFE | 0.3-0.5 | Agent anti-dripping |
| Huaora 1010 | 0.2 | Ka aukati i te paheketanga |
Nga Whakaaro Hoahoa Matua:
- Kōwhiringa Resin:
- Whakamahia nga tohu HIPS tino kaha (hei tauira,Chimei PH-888,Taifa PG-33) me te 5–6 kJ/m². Ko te SEBS ka whakanui ake i te pakari.
- Mana Rere:
- AHP/MCA whakaiti MFI; utu ki te whakahinuhinu (hei tauira, te parawini wai) me te whakahiato (hei tauira, te hinu soya kua whakahaehaehia).
- Mena kei te iti tonu te MFI, taapirihia2–3 haora TPUkia pai ake te rere me te pakari.
- Te Whakamanatanga o te mura o te ahi:
- Ka taea te whakaheke i te AHP ki12 phki te honoa ki2–3 ph EGki te pupuri UL94 V-0.
- MoUL94 V-2, whakaitihia te utaina mura ki te whakaraupapa i te paanga/rere.
- Tawhā Whakairi werohanga:
- Te pāmahana:180–220°C(Ka karohia te whakahekenga AHP/HIPS).
- Tere werohanga:Waenga-teiteikia kore e oti te whakakii.
Mahinga e Manakohia ana:
| Taonga | Uara Whainga | Paerewa Whakamatau |
| Te kaha o te paanga | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/10 min | ASTM D1238 |
| Te mura o te mura | UL94 V-0 (1.6 mm) | UL94 |
| Te kaha tensile | ≥25 MPa | ISO 527 |
4. Rongoa Ake
- Kōwhiringa Utu-Tirohanga: Whakakapihia te AHP ki tetahi waahangaūkuikui whero microencapsulated (3-5 phr), engari tirohia te herenga tae (whero-parauri).
- Whakamana: Whakahaerehia nga whakamatautau-iti ki te whakataurite i te paanga me te aukati mura i mua i te arotau i te rere.
