PBT Halogen-Free Flame Retardant Fausia Fa'amatalaga

PBT Halogen-Free Flame Retardant Fausia Fa'amatalaga

Ina ia faʻamalieina le faʻatulagaina o faʻamaʻi afi e leai se mea halogen mo le PBT, e taua tele le faapaleniina o le afi mumu, faʻamautu vevela, faʻaogaina o le vevela, ma mea faʻainisinia. O loʻo i lalo se taʻiala faʻapipiʻi sili ona lelei ma auʻiliʻiliga autu:

1. Tu'ufa'atasiga Fa'asao Mu'a

Filifiliga 1: Aluminium Hypophosphite + MCA (Melamine Cyanurate) + Zinc Borate

Mesini:

• Alumini Hypophosphite (Thermal stability> 300°C): Faʻamalosia le faʻavaeina o le char i le vaega faʻafefete ma faʻasaʻo PO· radicals i le vaega o le kesi e faʻalavelave ai gaioiga faʻamumu.
• MCA (Decomposition i le ~ 300°C): Endothermic decomposition e faʻasaʻo ai kasa inert (NH₃, H₂O), faʻafefeteina kasa mu ma taofiofia le faʻafefeteina.
• Zinc Borate (Decomposition> 300°C): Faʻaleleia le fausiaina o tioata tioata, faʻaitiitia le asu ma le susulu.

Fuafuaga Fautuaina:

• Aluminium Hypophosphite (10-15%) + MCA (5-8%) + Zinc Borate (3-5%).

Filifiliga 2: Manesium Hydroxide + Aluminum Hypophosphite + Fofosinate Fa'aletino (eg, ADP)

Mesini:

• Suia Magnesium Hydroxide (Decomposition ~ 300 ° C): Faʻasagaga o luga (silane / titanate) faʻaleleia le faʻasalalau ma le mautu o le vevela; endothermic malulu e fa'aititia ai le vevela o meafaitino.
• Phosphinate fa'aletino (fa'ata'ita'iga, ADP, mautu vevela > 300°C): Fa'asao le afi fa'a'aisa maualuga, fa'atasi ma faiga phosphorus-nitrogen.

Fuafuaga Fautuaina:

• Magnesium Hydroxide (15-20%) + Aluminium Hypophosphite (8-12%) + ADP (5-8%).

2. Filifiliga Synergists

• Nano-omea/Talc (2-3%): Fa'aleleia le lelei o le char ma mea fa'ainisinia a'o fa'aitiitia le utaina o le mumu.
• PTFE (0.2-0.5%): Anti-dripping agent e puipuia ai matāua mu.
• Siliko Pa'u (2-4%): Fa'alauiloa le fa'aputuina o ga'o mafiafia, fa'aleleia le fa'alumaina o le mumu ma le iila i luga.

3. Tuufaatasiga e Aloese ai

• Aluminum Hydroxide: Faʻaleagaina i le 180-200 ° C (i lalo ifo o le vevela o le PBT o le 220-250 ° C), e oʻo atu ai i le faʻaleagaina vave.
• Manesium Hydroxide e le suia: Manaomia togafitiga i luga ole laiga e puipuia ai le faʻapipiʻiina ma le vevela ile taimi ole gaioiga.

4. Fautuaga mo le Fa'aleleia o Galuega

• Togafitiga Laufanua: Fa'aaogā mea fa'apipi'i silane i luga ole Mg(OH)₂ ma le zinc borate e fa'aleleia ai le ta'ape ma feso'ota'iga va'aiga.
• Puleaina o le Vevela: Faʻamautinoa le vevela faʻaleagaina o le afi> 250°C e aloese ai mai le faʻaleagaina.
• Paleni Meatotino Fa'ainisinia: Totogi mo le fa'aitiitia o le malosi e fa'aaoga ai nano-fillers (fa'ata'ita'iga, SiO₂) po'o mea fa'amalo (eg, POE-g-MAH).

5. Fa'ata'ita'iga Fa'atusa

6. Su'ega Autu o Su'ega

• Mumu Fa'aletonu: UL94 V-0 (1.6mm), LOI> 35%.
• Fa'asao vevela: TGA toega > 25% (600°C).
• Meatotino Fa'ainisinia: Malosi fa'amalosi > 45 MPa, a'afiaga fa'ailo > 4 kJ/m².

E ala i le fa'amalieina o fa'atatau, e mafai ona maua le fa'aletonu o le mu e aunoa ma se halogen a'o fa'atumauina le fa'atinoga atoa a le PBT.
