PBT Halogen-Enwere Ntụtu aka na-egbochi ire ọkụ

Iji kwalite nhazi nke ọkụ na-ere ọkụ na-enweghị halogen maka PBT, ọ dị mkpa iji dozie nrụpụta ire ọkụ, nkwụsi ike nke okpomọkụ, ndakọrịta okpomọkụ, na akụrụngwa. N'okpuru bụ atụmatụ nchịkọta kachasị mma yana nyocha isi:

1. Nchikota isi ire ere

Nhọrọ 1: Aluminom Hypophosphite + MCA (Melamine Cyanurate) + Zinc Borate

Usoro:

• Aluminium Hypophosphite (Nkwụsi ike nke okpomọkụ> 300 ° C): Na-akwalite nhazi cha cha n'ime oge condensed wee wepụta PO · radicals na mpaghara gas iji kwụsịtụ mmeghachi omume ọkụ ọkụ.
• MCA (Mbibi na ~ 300°C): Endothermic decomposition na-ewepụta gas inert (NH₃, H₂O), na-agbaze gas na-ere ọkụ ma na-egbochi mmiri na-agbaze.
• Zinc Borate (Nbibi> 300°C): Na-eme ka nguzobe cha cha enyo, na-ebelata anwụrụ ọkụ na ọkụ ọkụ.

Oke akwadoro:

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

Nhọrọ 2: Magnesium Hydroxide + Aluminom Hypophosphite + Organic Phosphinate (dịka ọmụmaatụ, ADP) gbanwetụrụ elu.

Usoro:

• Magnesium Hydroxide gbanwetụrụ (Decomposition ~ 300 ° C): ọgwụgwọ elu (silane / titanate) na-eme ka mgbasawanye na nkwụsi ike ọkụ; endothermic jụrụ oyi na-ebelata okpomọkụ ihe onwunwe.
• Organic Phosphinate (dịka ọmụmaatụ, ADP, nkwụsi ike nke okpomọkụ> 300°C): Ọ na-egbochi ire ọkụ na-arụ ọrụ nke ukwuu, na-emekọrịta na sistemu phosphorus-nitrogen.

Oke akwadoro:

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

2. Nhọrọ Synergists

• Nano-clay/Talc (2-3%): Na-emeziwanye ogo cha cha yana ihe arụrụ arụ ma na-ebelata ibu ọkụ na-egbochi ọkụ.
• PTFE (0.2-0.5%): Onye na-egbochi ntapu iji gbochie ụmụ irighiri mmiri ọkụ.
• Silicone ntụ ntụ (2-4%): Na-akwalite nguzobe cha cha, na-eme ka ire ọkụ na-azụ azụ na nchapụta elu.

3. Ngwakọta iji zere

• Aluminom Hydroxide: Decomposes na 180-200 ° C (n'okpuru PBT nhazi okpomọkụ nke 220-250 Celsius C), na-eduga na akaghi aka mmebi.
• Magnesium Hydroxide na-agbanweghị: Na-achọ ọgwụgwọ elu iji gbochie agglomeration na thermal ire ere n'oge nhazi.

4. Atụmatụ nkwalite arụmọrụ

• Ọgwụgwọ dị n'elu: Jiri ndị na-ejikọta silane na Mg(OH)₂ na zinc borate iji kwalite mgbasasa na njikọta ihu.
• Na-ahazi njikwa okpomọkụ: Gbaa mbọ hụ na ire ere ire ere ọkụ> 250°C iji zere mmebi.
• Nhazi Ngwongwo Mechanical: Kwuo maka mfu ike site na iji nano-fillers (dịka, SiO₂) ma ọ bụ ihe siri ike (dịka, POE-g-MAH).

5. Ụdị ihe atụ

6. Metrics ule isi

• Nkwụghachi ọkụ: UL94 V-0 (1.6mm), LOI> 35%.
• Nkwụsi ike nke okpomọkụ: ihe fọdụrụ TGA> 25% (600°C).
• Ihe arụrụ arụ: Ike mgbagharị> 45 MPa, mmetụta a na-ahụ anya> 4 kJ/m².

Site n'imezigharị ọnụ ọgụgụ ndị ahụ nke ọma, enwere ike nweta nkwụghachi ọkụ na-enweghị halogen dị elu ma na-ejigide arụmọrụ PBT n'ozuzu ya.
