Icyifuzo cya Flame-Retardant Igishushanyo mbonera cya Halogen-Yubusa-Impinduka nyinshi-Polystirene (HIPS)
Ibisabwa byabakiriya.
1. Fosifore-Azote Synergistic Flame-Retardant Sisitemu
HIPS Flame-Retardant formulaire (Imbonerahamwe 1)
| Ibigize | Kuremera (interuro) | Ijambo |
| HIPS resin | 100 | Ibikoresho shingiro |
| Amonium polyphosifate (APP) | 15-20 | Inkomoko ya Fosifore |
| Melamine cyanurate (MCA) | 5-10 | Inkomoko ya azote, ihuza na APP |
| Ikarita yagutse (EG) | 3-5 | Gutezimbere gushiraho char |
| Umuti urwanya ibitonyanga (PTFE) | 0.3-0.5 | Irinda ibitonyanga bishongeshejwe |
| Compatibilizer (urugero, MAH yashizwemo HIPS) | 2-3 | Itezimbere |
Ibiranga:
- IbyagezwehoUL94 V-0ukoresheje intumecent char form kuva muri APP / MCA.
- Halogen idafite ibidukikije kandi yangiza ibidukikije, ariko irashobora kugabanya imiterere yubukanishi; gutezimbere birakenewe.
2. Metal Hydroxide Flame-Retardant Sisitemu
Gutegura HIPS (Imbonerahamwe 2)
| Ibigize | Kuremera (interuro) | Ijambo |
| HIPS resin | 100 | - |
| Hydroxide ya aluminium (ATH) | 40-60 | Flame primaire retardant |
| Hydroxide ya Manyeziyumu (MH) | 10-20 | Gukomatanya na ATH |
| Umukozi uhuza Silane (urugero, KH-550) | 1-2 | Itezimbere kuzuza |
| Gukomera (urugero, SEBS) | 5-8 | Indishyi zo gutakaza imbaraga |
Ibiranga:
- Irasaba> 50%kuri UL94 V-0, ariko itesha agaciro imbaraga ningendo.
- Bikwiranye numwotsi muke / uburozi buke (urugero, inzira ya gari ya moshi).
3. Sisitemu ya Fosifore-Azote Sisitemu yo Guhuza (Aluminium Hypophosphite + MCA)
Gutezimbere HIPS
| Ibigize | Kuremera (interuro) | Imikorere / Inyandiko |
| HIPS (urwego-rwo hejuru cyane, urugero, PS-777) | 100 | Ibikoresho shingiro (ingaruka ≥5 kJ / m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Inkomoko ya fosifore, ituze ryumuriro |
| Melamine cyanurate (MCA) | 6-8 | Inkomoko ya azote, ihuza na AHP |
| SEBS / SBS | 8-10 | Gukomera gukomeye kugirango bigerweho ≥7 kJ / m² |
| Amazi ya soya ya paraffine / epoxisize yamavuta ya soya | 1-2 | Amavuta, atezimbere / gutatanya |
| PTFE | 0.3-0.5 | Umuti urwanya gutonyanga |
| Antioxydeant 1010 | 0.2 | Irinde kwangirika |
Ibitekerezo by'ingenzi byashizweho:
- Guhitamo:
- Koresha amanota menshi ya HIPS (urugero,Chimei PH-888,Taifa PG-33) hamwe nimbaraga zingaruka za 5-6 kJ / m². SEBS irusheho kongera ubukana.
- Kugenzura imigendekere:
- AHP / MCA kugabanya MFI; indishyi hamwe n'amavuta (urugero, paraffine y'amazi) cyangwa plasitike (urugero, amavuta ya soya ya epoxiside).
- Niba MFI ikomeje kuba hasi, ongeraho2-3 interuro TPUkunoza imigendekere no gukomera.
- Kwemeza gucana umuriro:
- AHP irashobora kugabanuka kuri12 interuroniba ihujwe na2-3 interuro EGkubungabunga UL94 V-0.
- KuriUL94 V-2, gabanya flame retardant imitwaro kugirango ushire imbere ingaruka / gutemba.
- Ibikoresho byo gutera inshinge:
- Ubushyuhe:180-220 ° C.(irinde gutesha agaciro AHP / HIPS).
- Umuvuduko wo gutera inshinge:Hagatikugirango wirinde kuzura kutuzuye.
Imikorere iteganijwe:
| Umutungo | Agaciro Intego | Ikizamini |
| Ingaruka imbaraga | ≥7 kJ / m² | ISO 179 / 1eA |
| MFI (200 ° C / 5 kg) | 5–7 g / 10min | ASTM D1238 |
| Kubura umuriro | UL94 V-0 (1,6 mm) | UL94 |
| Imbaraga zingana | ≥25 MPa | ISO 527 |
4. Ibindi bisubizo
- Igiciro-Kumva neza: Simbuza AHP igice hamwemicroencapsulated fosifore itukura (3-5 interuro), ariko andika ibara rigarukira (umutuku-umutuku).
- Kwemeza: Kora ibigeragezo bito kugirango uhuze ingaruka na flame retardancy mbere yo guhitamo neza.
