Hangarau Hanga me te Tukatuka Ārai Mumura Kore-Halogen mō te Resin Epoxy
Kei te rapu te kiritaki i tētahi matū ārai ahi e pai ana ki te taiao, kāore he halogen, kāore hoki he konganuku taumaha e tika ana mō te kapia epoxy me te pūnaha whakamaroke anhydride, e hiahia ana kia tutuki i te UL94-V0. Me waiho te matū whakamaroke hei matū whakamaroke epoxy pāmahana teitei me te Tg i runga ake i te 125°C, me whakamaroke wera i te 85–120°C me te tauhohenga puhoi i te pāmahana rūma. Kei raro nei te whakatakotoranga taipitopito e ai ki te tono a te kiritaki.
I. Pūnaha Hanga Ārai Mura
1. Pūnaha Ārai Mura Matua: Te Hononga o te Phosphorus-Hauota
Ripanga Mōhiohio Ārai Mura
| Ārai Mura | Tikanga | Te Utaina i Manakohia | Ngā Kōrero |
|---|---|---|---|
| Konumohe hypophosphate | Te ātete mura ā-wāhanga-whakakotahi, ka hanga he paparanga waro konupūmā konupūmā | 10–15% | Ārai mura tuatahi, pāmahana pirau >300°C |
| Haukinia polyphosphate (APP) | Te ātete mura intumescent, ka mahi tahi me te hypophosphate konumohe | 5–10% | E hiahiatia ana he APP ātete-waikawa |
| Melamine cyanurate (MCA) | Pūtake hauota, whakarei ake i te mahi tahi o te whākawa, pehi i te paowa | 3–5% | Ka whakaiti i te maturuturu |
2. Ngā Āwhina Ārai Mura me ngā Pūtahitahi
Ripanga Mōhiohio Āwhina mō ngā Ārai Mura
| Ārai Mura | Tikanga | Te Utaina i Manakohia | Ngā Kōrero |
|---|---|---|---|
| Konutea borate | Ka whakatairanga i te hanganga o te ngako, ka pehi i te kanapa i muri mai | 2–5% | Ka whakaroa pea te nui rawa o te wā i te whakamaroke |
| Waikawa konumohe pai | Te whakamatao i roto i te werawera, te pehi paowa | 5–8% | Whakahaerehia te uta (kia kore ai e whakaitihia te Tg) |
3. Tauira Whakatakotoranga (Tapeke Utaina: 20–30%)
Te Hanganga Tūāpapa (E pā ana ki te Ihirangi Resin Katoa)
| Wāhanga | Ihirangi (E pā ana ki te Resin) |
|---|---|
| Konumohe hypophosphate | 12% |
| Taupānga | 8% |
| MCA | 4% |
| Konutea borate | 3% |
| Waikawa konumohe | 5% |
| Utaina Katoa | 32% (ka taea te whakarerekē ki te 25–30%) |
II. Ngā Hipanga Tukatuka Matua
1. Te Whakaranu me te Marara
A. Te Maimoatanga i mua i te:
- Whakamaroketia te konumohe hypophosphate, te APP, me te MCA i te 80°C mō ngā hāora e 2 (kia kore ai e mimiti te makuku).
- Whakamahia ngā whakakī kore-waro (waikawa konumohe, konutea borate) ki te kaihoko honohono silane (hei tauira, KH-550).
B. Raupapa Whakaranu:
- Kapia epoxy + Ngā ārai mura (60°C, whakaohokia mō te 1 hāora)
- Tāpirihia he matū whakaora anhydride (kia mau te pāmahana ki raro i te 80°C)
- Te tango hau korehau (-0.095 MPa, 30 meneti)
2. Tukanga Whakaora
Te Whakaora i te Hipanga (Ka whakataurite i te pumau o te ātete mura me te Tg teitei):
- 85°C / 2h (he puhoi te tīmatanga, he whakaiti i ngā mirumiru)
- 120°C / 2h (kia tino tauhohe te anhydride)
- 150°C / 1h (ka whakanui ake i te mātotoru hononga whakawhiti, Tg >125°C)
3. Ngā Tuhipoka Matua
- Te whakahaere i te matotoru: Mena he nui rawa te matotoru, tāpirihia he 5% te waiwhakarewa epoxy tauhohe (hei tauira, AGE).
- Te whakaroa i te whakamaroke: Whakamahia te methylhexahydrophthalic anhydride (MeHHPA) tāpirihia rānei te 0.2% 2-ethyl-4-methylimidazole (ka whakaroa i te tauhohenga pāmahana rūma).
III. Manatoko me te Whakatikatika Mahi
1. Ātete ki te mura:
- Whakamātautau UL94 V0 (matotoru 1.6mm): Kia iti iho i te 10 hēkona te roa o te tahunga, kaua e maturuturu.
- Ki te kore e ranea: Whakanuia te konumohe hypophosphate (+3%), te APP rānei (+2%).
2. Mahi Wera:
- Whakamātautau DSC mō te Tg: Mena kei raro iho i te 125°C te Tg, whakaitihia te hauwai konumohe (ka whakaitihia te Tg nā te pānga werawera).
3. Ngā Āhuatanga Ā-ringa:
- Ki te heke te kaha piko, tāpirihia he 1–2% nano-silica hei whakapakari.
IV. Ngā Take me ngā Otinga Pea
Ripanga Take me ngā Otinga Ārai Mura
| Putanga | Take | Otinga |
|---|---|---|
| Te whakamaroke kore i oti | Te mimiti makuku, te pokanoa pH rānei mai i ngā ārai mura | Ngā whakakī maroke-mua, whakamahia he APP ātete-waikawa |
| Te rere ngoikore o te kapia | Te nui rawa o te utaina o te whakakī | Whakaitihia te hauwai konumohe ki te 3%, tāpirihia rānei he waiwhakarewa |
| Te rahunga o te UL94 | Kāore i te rawaka te mahi tahi a te PN | Whakanuia te MCA (ki te 6%), te hypophosphate konumohe rānei (ki te 15%) |
V. Te Hanga Rerekē (Mēnā e Hiahiatia ana)
Whakakapia tētahi wāhanga o te APP ki ngā hua DOPO (hei tauira, DOPO-HQ):
- Ka whakaitihia e te 8% DOPO-HQ + 10% konumohe hypophosphate ka whakaitihia te uta katoa (~18%) me te pupuri tonu i te mahi.
Ka whakatauritehia e tēnei huinga te ātete mura, te haumaru taiao, me te mahi pāmahana teitei. E taunakihia ana kia whakamātauria ngā whakamātautau iti (500g) i mua i te whakaputanga katoa.
