Ammonium polyphosphate (APP)	Ọkụ na-adịghị mma, na-ejikọta ya na aluminom hypophosphite	5–10%	Achọrọ APP na-eguzogide acid
Melamine cyanurate (MCA)	Isi iyi nitrogen, na-eme ka njikọ phosphorus dịkwuo mma, na-egbochi anwụrụ ọkụ	3–5%	Na-ebelata ntapụ mmiri

2. Ndị na-egbochi ire ọkụ na ndị na-eme ka mmadụ na ibe ya dị n'otu

Tebụl Ozi Ndị Na-egbochi Ọkụ Ire Ọkụ

Ihe na-egbochi ire ọkụ	Usoro	Ibugo akwadoro	Okwu ndị e kwuru
Zinc borate	Na-akwalite nhazi nke char, na-egbochi mmetụta ọjọọ nke ihe mgbu azụ	2–5%	Oke oke nwere ike ime ka ọ ghara ịgwụ ngwa ngwa

II. Nzọụkwụ Nhazi Isi

1. Ịgwakọta na Mgbasa

A. Ọgwụgwọ tupu oge eruo:

A na-etinye aluminom hypophosphite, APP, na MCA na okpomọkụ 80°C ruo awa abụọ (na-egbochi mmiri ịmịkọrọ).
Jiri ihe njikọ silane (dịka ọmụmaatụ, KH-550) gwọọ ihe ndị na-eme ka ihe dị n'ime ahụ ghara ịdị ndụ (aluminum hydroxide, zinc borate).

B. Usoro Ngwakọta:

Resin Epoxy + ihe na-egbochi ire ọkụ (60°C, gwakọta ya maka otu awa)
Tinye ihe na-agwọ anhydride (dobe okpomọkụ <80°C)
Mkpọpụ ikuku (-0.095 MPa, nkeji iri atọ)

2. Usoro Ịgwọ Ọrịa

Ọgwụgwọ Nzọụkwụ (Na-edozi nkwụsi ike nke ihe na-egbochi ire ọkụ na Tg dị elu):

85°C / awa 2 (mmalite nwayọ nwayọ, na-ebelata afụfụ)
120°C / awa 2 (na-eme ka mmeghachi omume anhydride zuru oke)
150°C / 1h (na-eme ka njupụta njikọta dịkwuo elu, Tg >125°C)

3. Ihe Ndị Dị Mkpa

Njikwa Viscosity: Ọ bụrụ na viscosity dị oke elu, tinye 5% reactive epoxy diluent (dịka ọmụmaatụ, AGE).
Ọgwụgwọ oge: Jiri methylhexahydrophthalic anhydride (MeHHPA) ma ọ bụ tinye 0.2% 2-ethyl-4-methylimidazole (na-ebelata mmeghachi omume okpomọkụ ụlọ).

III. Nnwale na Mgbanwe Arụmọrụ

1. Nkwụsị ire ọkụ:

Nnwale UL94 V0 (ọkpụrụkpụ 1.6mm): Hụ na oge ọkụ adịghị ihe karịrị sekọnd 10, enweghị ntapụ mmiri.
Ọ bụrụ na ọ daa: Mee ka aluminom hypophosphite (+3%) ma ọ bụ APP (+2%) dịkwuo elu.

2. Arụmọrụ okpomọkụ:

Nnwale DSC maka Tg: Ọ bụrụ na Tg erughị 125°C, belata aluminom hydroxide (na-ebelata Tg n'ihi mmetụta endothermic).

3. Njirimara Mekaniki:

Ọ bụrụ na ike flexural ada, tinye 1–2% nano-silica maka nkwado.

IV. Nsogbu na Ngwọta Nwere Ike Ime

Isiokwu na Ihe Ngwọta nke Ihe Na-egbochi Ọkụ

Nsogbu	Ihe kpatara ya	Ngwọta
Ọgwụgwọ zuru oke	Ntinye mmiri ma ọ bụ nnyonye anya pH site na ihe ndị na-egbochi ọkụ	Akpọchaa ihe ndị na-ejuputa ihe, jiri APP na-eguzogide acid
