Bii o ṣe le dinku iwuwo ẹfin fun alemora iposii pẹlu AHP ati MCA ti ina?

Awọn afikun ti aluminiomu hypophosphite ati MCA si iposii alemora esi ni ga èéfín itujade. Lilo borate zinc lati dinku iwuwo ẹfin ati itujade ṣee ṣe, ṣugbọn agbekalẹ ti o wa tẹlẹ nilo lati wa ni iṣapeye fun ipin naa.

1. Ẹfin idasile Mechanism of Zinc Borate

Zinc borate jẹ imunadoko eefin to munadoko ati amuṣiṣẹpọ ina-retardant. Awọn ilana rẹ pẹlu:

• Char Ibiyi igbega: Fọọmu kan ipon eedu Layer nigba ijona, sọtọ atẹgun ati ooru, ati atehinwa flammable gaasi Tu.
• Idena eefin: Catalyzes awọn aati ọna asopọ agbelebu lati dinku iran patiku ẹfin, idinku iwuwo ẹfin (paapaa munadoko fun awọn polima bi iposii).
• Ipa Synergistic: Ṣe ilọsiwaju idaduro ina nigba ti a ba ni idapo pẹlu irawọ owurọ-orisun (fun apẹẹrẹ, aluminiomu hypophosphite) ati nitrogen-orisun (fun apẹẹrẹ, MCA) ina retardants.

2. Yiyan tabi Afikun Ẹfin Suppressants

Fun iṣapeye siwaju sii ti idinku ẹfin, ronu awọn ojutu amuṣiṣẹpọ wọnyi:

• Awọn akojọpọ Molybdenum(fun apẹẹrẹ, zinc molybdate, molybdenum trioxide): Ti o munadoko diẹ sii ju borate zinc ṣugbọn iye owo; niyanju lati parapo pẹlu zinc borate (fun apẹẹrẹ, zinc borate: zinc molybdate = 2: 1).
• Aluminiomu / magnẹsia HydroxideNbeere ikojọpọ giga (20-40 phr), eyiti o le ni ipa awọn ohun-ini ẹrọ iposii—ṣatunṣe ni iṣọra.

3. Niyanju Fọọmù Awọn atunṣe

A ro pe ipilẹṣẹ atilẹba jẹaluminiomu hypophosphite + MCA, Eyi ni awọn itọnisọna iṣapeye (da lori awọn ẹya 100 epoxy resini):

Aṣayan 1: Afikun taara ti Zinc Borate

• Aluminiomu hypophosphite: Din lati 20-30 phr si15-25 phr
• MCA: Din lati 10-15 phr si8-12 phr
• Zinc borate: Fi kun5-15 phr(bẹrẹ idanwo ni 10 phr)
• Lapapọ akoonu idaduro ina: Jeki ni30-40 phr(yago fun awọn iye ti o pọju ti o ni ipa iṣẹ alamọ).

Aṣayan 2: Zinc Borate + Zinc Molybdate Synergy

• Aluminiomu hypophosphite:15-20 phr
• MCA:5-10 phr
• Zinc borate:8-12 phr
• Zinc molybdate:4-6 phr
• Lapapọ akoonu idaduro ina:30-35 phr.

4. Key afọwọsi Metiriki

• Idaduro ina: UL-94 sisun inaro, awọn idanwo LOI (afojusun: V-0 tabi LOI> 30%).
• Ẹfin iwuwoLo oluyẹwo iwuwo ẹfin (fun apẹẹrẹ, iyẹwu ẹfin NBS) lati ṣe afiwe idinku ninu Iwọn iwuwo Ẹfin (SDR).
• Darí Properties: Rii daju pe agbara fifẹ ati agbara adhesion pade awọn ibeere lẹhin imularada.
• Ilana ṣiṣe: Jẹrisi pipinka aṣọ ti awọn idaduro ina laisi ipa iki tabi akoko imularada.

5. Awọn ero

• Patiku Iwon Iṣakoso: Jade fun nano-won sinkii borate (fun apẹẹrẹ, patiku iwọn <1 μm) lati mu pipinka.
• Dada Iyipada: Ṣe itọju borate zinc pẹlu aṣoju asopọ silane lati jẹki ibamu pẹlu resini iposii.
• Ibamu Ilana: Rii daju pe awọn idaduro ina ti o yan pade RoHS, REACH, ati awọn ilana miiran.

6. Ilana Apeere (Itọkasi)

7. Lakotan

• Zinc borate jẹ yiyan ti o munadoko fun idinku itujade ẹfin. Ṣeduro fifi kun10-15 phrlakoko ti o dinku iwọntunwọnsi aluminiomu hypophosphite/MCA akoonu.
• Fun idinku ẹfin siwaju, parapo pẹlu awọn agbo ogun molybdenum (fun apẹẹrẹ,4-6 phr).
• Ifọwọsi idanwo jẹ pataki lati dọgbadọgba idaduro ina, idinku ẹfin, ati awọn ohun-ini ẹrọ.
