- Tsis muaj halogen thiab zoo rau ib puag ncig, tab sis tej zaum yuav txo cov khoom siv kho tshuab; xav tau kev kho kom zoo.
2. Lub Tshuab Hluav Taws Xob Hlau Hydroxide
Kev Tsim Qauv HIPS (Rooj 2)
| Cheebtsam | Thauj khoom (phr) | Cov Lus Cim |
| HIPS resin | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Cov nplaim taws tseem ceeb |
| Magnesium hydroxide (MH) | 10-20 | Ua ke nrog ATH |
| Tus neeg sawv cev txuas Silane (piv txwv li, KH-550) | 1-2 | Txhim kho cov khoom sib kis |
| Cov khoom siv tawv (piv txwv li, SEBS) | 5-8 | Them rau qhov poob ntawm lub zog cuam tshuam |
Cov yam ntxwv:
- Yuav tsum tau> 50% thauj khoomrau UL94 V-0, tab sis ua rau lub zog cuam tshuam thiab ntws qis dua.
- Haum rau cov ntawv thov uas muaj pa luam yeeb tsawg/tsawg lom (piv txwv li, kev thauj mus los ntawm tsheb ciav hlau).
3. Phosphorus-Nitrogen Synergistic System (Aluminium Hypophosphite + MCA)
Kev Tsim Kho HIPS Zoo Tshaj Plaws
| Cheebtsam | Thauj khoom (phr) | Kev Ua Haujlwm/Cov Lus Cim |
| HIPS (qib cuam tshuam siab, piv txwv li, PS-777) | 100 | Cov khoom siv hauv paus (cuam tshuam ≥5 kJ / m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Qhov chaw phosphorus, kev ruaj khov thermal |
| Melamine cyanurate (MCA) | 6-8 | Qhov chaw nitrogen, sib koom tes nrog AHP |
| SEBS/SBS | 8-10 | Cov khoom siv tawv tseem ceeb rau kev cuam tshuam ≥7 kJ / m² |
| Cov roj kua paraffin / epoxidized taum pauv | 1-2 | Cov roj nplua nyeem, txhim kho kev ntws / kev tawg |
| PTFE | 0.3-0.5 | Tus neeg sawv cev tiv thaiv dej ntws |
| Cov tshuaj tua kab mob 1010 | 0.2 | Tiv thaiv kev puas tsuaj |
Cov Kev Xav Txog Kev Tsim Qauv Tseem Ceeb:
- Kev Xaiv Cov Roj Hmab:
- Siv cov qib HIPS uas muaj feem cuam tshuam siab (piv txwv li,Chimei PH-888,Taifa PG-33) nrog lub zog cuam tshuam ntawm 5–6 kJ / m². SEBS ntxiv txhim kho kev ruaj khov.
- Kev Tswj Xyuas Kev Nqus Dej:
- AHP/MCA txo MFI; them nrog cov roj nplua nyeem (piv txwv li, kua paraffin) lossis cov yas (piv txwv li, roj taum pauv epoxidized).
- Yog tias MFI tseem qis, ntxiv2–3 phr TPUlos txhim kho kev ntws thiab kev tawv.
- Kev Txheeb Xyuas Kev Tiv Thaiv Hluav Taws Kub:
- AHP tuaj yeem txo qis rau12 phryog tias ua ke nrog2–3 phr EGkom tswj tau UL94 V-0.
- RauUL94 V-2, txo cov khoom thauj uas tiv taus hluav taws kom muab qhov tseem ceeb rau kev cuam tshuam/kev ntws.
- Cov Txheej Txheem Txhaj Tshuaj Molding:
- Kub:180–220°C(zam kom tsis txhob muaj kev puas tsuaj ntawm AHP/HIPS).
- Kev txhaj tshuaj ceev:Nruab nrab-siabkom tiv thaiv kev sau tsis tiav.
Kev Ua Tau Zoo Uas Xav Tau:
| Vaj tse | Tus Nqi Lub Hom Phiaj | Kev Ntsuas Tus Qauv |
| Lub zog cuam tshuam | ≥7 kJ / m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/10 feeb | ASTM D1238 |
| Kev tiv thaiv hluav taws | UL94 V-0 (1.6 hli) | UL94 |
| Lub zog tensile | ≥25 MPa | ISO 527 |
4. Lwm Txoj Kev Daws Teeb Meem
- Kev Xaiv Uas Muaj Kev Xav Tau Tus Nqi: Hloov AHP ib feem nrogcov phosphorus liab uas muaj cov tshuaj me me (3–5 phr), tab sis nco ntsoov qhov txwv xim (xim av liab).
- Kev lees paubUa qhov kev sim me me kom sib npaug qhov cuam tshuam thiab qhov hluav taws kub ua ntej ua kom cov dej ntws zoo.
