Indlela yokunciphisa ingxinano yomsi we-epoxy adhesive nge-flame retardant AHP kunye ne-MCA ?

Ukongezwa kwe-aluminium hypophosphite kunye ne-MCA kwi-adhesive epoxy kubangela ukukhutshwa komsi ophezulu. Ukusebenzisa i-zinc borate ukunciphisa ingxinano yomsi kunye nokukhutshwa kwayo kunokwenzeka, kodwa ukwakheka okukhoyo kufuneka kwandiswe kumlinganiselo.

1. Indlela yokuNqanda umsi yeZinc Borate

I-Zinc borate sisithinteli esisebenzayo sokucinezela umsi kunye ne-synergist ye-flame-retardant. Iindlela zayo ziquka:

• UkuKhuthazwa koLwakhiwo lweChar: Yenza umaleko oshinyeneyo we-char ngexesha lokutsha, ukwahlula ioksijini kunye nobushushu, kunye nokunciphisa ukukhutshwa kwerhasi enokutsha.
• Ukuthintelwa komsi: I-Catalyzes reaction cross-linking reactions ukunciphisa ukuveliswa kwamasuntswana omsi, ukunciphisa ingxinano yomsi (isebenza ngokukodwa kwiipolima ezifana ne-epoxy).
• Isiphumo se-Synergistic: Yongeza ukubuyiswa komlilo xa idityaniswe ne-phosphorus-based (umzekelo, i-aluminium hypophosphite) kunye ne-nitrogen-based (umz., i-MCA) i-flame retardants.

2.Ezinye okanye ezoNgezelelweyo zokuTshaba uMsi

Ukwandisa ngakumbi ukuthomalalisa umsi, qwalasela ezi zisombululo zilandelayo:

• Molybdenum Compounds(umzekelo, i-zinc molybdate, i-molybdenum trioxide): Isebenza ngakumbi kune-zinc borate kodwa ibiza kakhulu; kucetyiswa ukudibanisa ne-zinc borate (umzekelo, i-zinc borate: i-zinc molybdate = 2: 1).
• Aluminiyam / Magnesium Hydroxide: Ifuna ukulayisha okuphezulu (i-20-40 phr), enokuthi ichaphazele iipropati ze-epoxy mechanical-lungisa ngokucophelela.

3. Ulungelelwaniso loqulunqo olucetyiswayo

Kucingelwa ukuba ulwakhiwo lokuqala luyiyoaluminiyam hypophosphite + MCA, nantsi izalathiso zokulungiselela (ngokusekwe kumalungu ali-100 epoxy resin):

Inketho 1: Ukongezwa ngokuthe ngqo kweZinc Borate

• Aluminiyam hypophosphite: Nciphisa ukusuka 20-30 phr ukuya15-25 phr
• MCA: Nciphisa ukusuka 10-15 phr ukuya8-12 phr
• I-zinc borate: Yongeza5-15 phr(qala ukuvavanya nge-10 phr)
• Umxholo opheleleyo wokubuyiswa komlilo: Qhubeka30-40 phr(ukuphepha ubuninzi obugqithisileyo obuchaphazela ukusebenza kwe-adhesive).

Inketho yesi-2: I-Zinc Borate + i-Zinc Molybdate Synergy

• I-Aluminiyam hypophosphite:15-20 phr
• I-MCA:5-10 phr
• Iborate yeZinc:8-12 phr
• Zinc molybdate:4-6 phr
• Umxholo opheleleyo wokubuyiswa komlilo:30-35 phr.

4. Iimetriki zoQinisekiso olungundoqo

• Ukubuyiswa komlilo: UL-94 ukutshisa ngokuthe nkqo, iimvavanyo ze-LOI (injongo: V-0 okanye i-LOI> 30%).
• Ukuxinana komsi: Sebenzisa isixhobo sokuvavanya uxinaniso lomsi (umzekelo, igumbi lomsi le-NBS) ukuthelekisa ukuncitshiswa komlinganiselo wokuxinana komsi (SDR).
• Iipropati zoomatshini: Qinisekisa ukuba amandla okuqina kunye namandla okubambelela ahlangabezana neemfuno emva kokunyanga.
• Ukuqhubekeka: Qinisekisa ukusasazwa okufanayo kweeretadants zomlilo ngaphandle kokuchaphazela i-viscosity okanye ixesha lokunyanga.

5. Iingqwalasela

• Ulawulo lobungakanani beNcam: Khetha i-nano-size zinc borate (umzekelo, ubungakanani be-particle <1 μm) ukuphucula ukusabalalisa.
• Ukuguqulwa komphezulu: Nyanga i-zinc borate nge-silane coupling agent ukuze uphucule ukuhambelana ne-epoxy resin.
• Ukuthotyelwa koMgaqo: Qinisekisa ukuba iiretardants ezikhethiweyo zomlilo ziyahlangabezana neRoHS, REACH, kunye neminye imimiselo.

6. Ukuqulunqwa koMzekelo (Reference)

7. Isishwankathelo

• I-Zinc borate lukhetho olusebenzayo lokunciphisa ukukhutshwa komsi. Ncoma ukongeza10-15 phrngelixa inciphisa ngokulinganisela i-aluminium hypophosphite / i-MCA umxholo.
• Ukuthomalalisa ngakumbi umsi, xuba neekhompawundi zemolybdenum (umz.,4-6 phr).
• Ukuqinisekiswa kovavanyo kuyimfuneko ukulinganisa ukunqanda amadangatye, ukunyanzeliswa komsi, kunye neempawu zoomatshini.
