Kodi mungapange bwanji flame retardant latex siponji?

Pazofunikira zoletsa malawi a siponji ya latex, zotsatirazi ndikuwunika kutengera zotsalira zingapo zalawi (aluminium hydroxide, zinc borate, aluminium hypophosphite, MCA) pamodzi ndi malingaliro opangira:

I. Kuwunika kwa Zomwe Zilipo Zoletsa Moto Wamoto

Aluminiyamu Hydrooxide (ATH)
Ubwino:

• Zokonda zachilengedwe, zotsika mtengo.
• Imagwira ntchito pakuwola kwa endothermic ndi kutulutsidwa kwa nthunzi wamadzi, koyenera machitidwe opanda halogen.

Zoyipa:

• Imafunika kutsitsa kwakukulu (30-50 phr) kuti ikhale yogwira mtima, yomwe ingakhudze kusungunuka kwa siponji ndi kachulukidwe.

Kagwiritsidwe:

• Zoyenera kupanga zoziziritsa kumoto.
• Analimbikitsa kuphatikiza ndi synergists (mwachitsanzo, nthaka borate).

Zinc Borate
Ubwino:

• Synergistic flame retardant, imawonjezera mphamvu ya ATH.
• Imalimbikitsa kupanga char ndikuletsa utsi.

Zoyipa:

• Zochepa zogwira mtima zikagwiritsidwa ntchito payekha; imafunika kuphatikiza ndi zina zoletsa moto.

Kagwiritsidwe:

• Adalangizidwa ngati synergist wa ATH kapena aluminium hypophosphite.

Aluminium Hypophosphite
Ubwino:

• Kuchita bwino kwambiri, kopanda halogen, kutsitsa kochepa (10-20 phr).
• Kukhazikika kwabwino kwamafuta, koyenera pakuwotcha kwambiri kwamoto.

Zoyipa:

• Mtengo wapamwamba.
• Kugwirizana ndi machitidwe a latex amafunika kutsimikiziridwa.

Kagwiritsidwe:

• Zoyenera pamiyezo yochedwa kwambiri yamoto (mwachitsanzo, UL94 V-0).
• Itha kugwiritsidwa ntchito yokha kapena kuphatikiza.

MCA (Melamine Cyanurate)
Ubwino:

• Nayitrogeni yochokera ku lawi retardant, kupondereza utsi.

Zoyipa:

• Osauka dispersibility.
• Ikhoza kusokoneza thovu.
• Kutentha kwakukulu kwa kuwonongeka (~ 300 ° C), kosagwirizana ndi kutentha kwa latex processing.

Kagwiritsidwe:

• Osavomerezeka ngati chofunikira; amafuna kutsimikizira koyesera.

II. Mapangidwe Ovomerezeka ndi Malingaliro a Njira

Kupanga 1: ATH + Zinc Borate (Njira Yachuma)
Zolemba:

• Aluminiyamu Hydrooxide (ATH): 30-40 phr
• Zinc Borate: 5-10 phr
• Dispersant (mwachitsanzo, silane coupling agent): 1-2 phr (imapangitsa kuti dispersibility)

Makhalidwe:

• Mtengo wotsika, wokonda zachilengedwe.
• Zoyenera pazambiri zochedwa kuchedwa kwamoto (monga UL94 HF-1).
• Mutha kuchepetsa kulimba kwa siponji pang'ono; Kukhathamiritsa kwa Vulcanization ndikofunikira.

Kupanga 2: Aluminium Hypophosphite + Zinc Borate (Njira Yothandiza Kwambiri)
Zolemba:

• Aluminiyamu Hypophosphite: 15-20 phr
• Zinc Borate: 5-8 phr
• Pulasitiki (mwachitsanzo, parafini yamadzimadzi): 2-3 phr (imapangitsa kuti ntchito ikhale yabwino)

Makhalidwe:

• Kugwiritsa ntchito bwino lawi lamoto, kutsitsa kochepa.
• Zoyenera pazochitika zofunidwa kwambiri (mwachitsanzo, kuwotcha kwa V-0).
• Kugwirizana kwa aluminium hypophosphite ndi kuyezetsa kwa latex.

Kupanga 3: ATH + Aluminium Hypophosphite (Njira Yoyenera)
Zolemba:

• Aluminiyamu Hydrooxide: 20-30 phr
• Aluminiyamu Hypophosphite: 10-15 phr
• Zinc Borate: 3-5 phr

Makhalidwe:

• Kuchepetsa mtengo ndi magwiridwe antchito.
• Amachepetsa kudalira chinthu chimodzi choletsa moto, kuchepetsa mphamvu ya thupi.

III. Malingaliro a Njira

Dispersibility:

• Zotsalira zamoto ziyenera kukhala pansi mpaka ≤5μm kuti zisasokoneze mawonekedwe a thovu.
• Pre-kubalalitsidwa mu latex kapena zida zosakaniza zothamanga kwambiri zimalimbikitsidwa.

Kuchiritsa Mikhalidwe:

• Sungani kutentha kwa machiritso (nthawi zambiri 110-130 ° C pa latex) kuti mupewe kuwonongeka msanga kwa zoletsa moto.

Kuyesa Magwiridwe:

• Mayesero ofunikira: Oxygen Index (LOI), Vertical Burn (UL94), Density, Resilience.
• Ngati kuchedwa kwamoto sikukwanira, pang'onopang'ono onjezerani ma aluminium hypophosphite kapena ATH ratios.

IV. Malangizo Owonjezera

Kuyesa kwa MCA:

• Ngati mukuyesa, gwiritsani ntchito 5-10 phr m'magulu ang'onoang'ono kuti muwone momwe kuchitira thovu.

Zitsimikizo Zachilengedwe:

• Onetsetsani kuti zoletsa moto zomwe zasankhidwa zikutsatira RoHS/REACH potumiza kunja.

Synergistic Blends:

• Ganizirani zoonjezera pang'ono za nanoclay (2-3 phr) kuti muwongolere zolepheretsa char.
