ʻO PP V2 Flame Retardant Masterbatch Reference Formulation
No ka loaʻa ʻana o ka UL94 V2 flame retardancy ma PP (polypropylene) masterbatches, pono kahi hui synergistic o nā mea pale ahi i ka wā e mālama ana i ka hana hana a me nā waiwai mechanical. Aia ma lalo iho kahi manaʻo hoʻolālā i hoʻopaʻa ʻia me nā wehewehe:
I. Manao Hookumu Kumu
ʻO ka hoʻokumu ʻana i ka lapalapa ahi:
| ʻāpana | Ke hoʻouka nei (wt%) | wehewehe hana |
| PP Resin | 50-60% | ʻO ka resin mea lawe (e paipai i ka helu helu helu hoʻoheheʻe kiʻekiʻe, e laʻa, MFI 20-30 g/10min) |
| Aluminum Hypophosphite | 15-20% | ʻO ke kumu waikawa, hoʻolaha i ka hoʻokumu ʻana o ka char, ka paʻa wela maikaʻi no ka hana PP |
| Zinc Borate | 5-8% | ʻO Synergistic flame retardant, hoʻopaʻa i ka uahi a hoʻonui i ka hoʻopaneʻe ʻana i ke ahi |
| Aluminum Hydroxide i hoʻololi ʻia i ka ʻili | 10-15% | Endothermic decomposition, hoʻohaʻahaʻa i ka mahana wela (ka mālama ʻana i ka ʻili, e laʻa, ka mea hoʻohui silane, ʻōlelo ʻia) |
| Dipentaerythritol (Di-PE) | 5-8% | ʻO ke kumu kalapona, hui pū me ke kumu waika e hana i ka intumescent char |
| Melamine Polyphosphate (MPP) | 3-5% | Hoʻokuʻu i nā kinoea inert e hoʻonui i ka intumescence |
| ʻAi ʻAi-Dripping Agen (PTFE) | 0.3-0.5% | Hoemi i ka kulu hehee (koko no V2, no ka mea, ua ae ia ka kulu) |
| ʻAikena (1010/168) | 0.3-0.5% | Kāohi i ka hōʻino ʻana o ka thermal oxidative i ka wā e hana ai |
| Lubricant (Zinc Stearate) | 0.5-1% | Hoʻomaikaʻi i ka flowability a me ka hoʻopuehu ʻana |
| Ka lawe kala a me ka puaʻa | E like me ka mea e pono ai | E koho i nā puaʻa kūpaʻa i ka wela kiʻekiʻe e pale i nā hopena me nā mea pale ahi |
II. Nā Lae Hoʻonui Kiʻi
- Synergistic Flame Retardant System
- Hoʻopaʻa ʻia ke ahi (IFR):ʻO ka alumini hypophosphite (kumu waikawa) + Di-PE (kumu kalapona) + MPP (kumu kinoea) hoʻokumu i kahi ʻōnaehana IFR, e hana ana i kahi papa char insulating e pale i ka wela a me ka oxygen.
- Zinc Borate Synergy:Hoʻopili me ka alumini hypophosphite e hana i kahi ʻāpana pale aniani, e hoʻonui ana i ka hoʻopaneʻe ahi.
- Hoʻololi ʻia ʻo Aluminum Hydroxide:Hoʻemi ʻia ka hoʻokuʻu ʻana o ka makū i ka wā o ka hana ʻana me ka hāʻawi ʻana i ka decomposition endothermic i ka haʻahaʻa o ka wela wela.
- Ka Hana Hana & Kaulike Hana
- Pono e mālama ʻia ka hoʻouka ʻana o ka lapalapa ahi35-45%e pale i ka poho waiwai mechanical.
- Hoʻohanakiʻekiʻe-MFI PP resin (e laʻa, PPH-Y40)e hoʻomaikaʻi i ka dispersion masterbatch a hōʻemi i ka viscosity.
- Nā Manaʻo hoʻāʻo a me ka hōʻoia
- UL94 Ho'āʻo Puhi Puhi:E hōʻoia i ka pio ʻana o ke ahi i loko60 kekonama hope o ʻelua mau ʻā.
- Hoʻāʻo Mechanical:E nānā i ka ikaika tensile (≥20 MPa) a me ka ikaika hopena (≥4 kJ/m²).
- ʻO ke kūpaʻa wela (TGA):E hōʻoia i nā mahana hoʻoheheʻe ʻana i ka lapalapa ahi e pili ana i ka pae hana PP (180–220°C).
III. Hoʻololi koho
- No ka hoʻopaneʻe ʻana o ke ahi kiʻekiʻe (e laʻa, V0):
- Hoʻonui i ka alumini hypophosphite i25%, hoʻohui2% silicone(ka puhi paka), a hookiekie i ka PTFE i0.8%.
- Nā noi pili kālā:
- E ho'ēmi i ka maʻiʻo MPP a hoʻonui i ka alumini hydroxide (e hōʻoia i ka paʻa o ka hana).
IV. Nā Manaʻo Nui
- Hanana Masterbatch:E hui mua i nā mea pale ahi me ka resin lawe;māhoe-screw extrusion (180–210°C)paipai ʻia.
- Hoʻomaloʻo Aluminum Hydroxide:Maloo ma110 ° C no 4 mau holae pale i nā ʻōhū i ka wā e hana ai.
- Di-PE/Aluminum Hypophosphite ratio:Mālama1:2 a hiki i 1:3no ka maikaʻi o ka hoʻokumu ʻana i ka char.
Me kēia hoʻonohonoho hoʻonohonoho ʻana a me ka hoʻoponopono ʻana,UL94 V2 hoʻopaneʻe ahihiki ke hoʻokō mau ʻia me ka mālama ʻana i ka hana hana a me ke kūpaʻa kala. Paipai ʻia nā hoʻokolohua liʻiliʻi no ka hoʻoponopono maikaʻi ʻana ma muli o nā hopena hoʻāʻo.
