• Ukusebenza okulinganiselweyo xa kusetyenziswe yedwa; ifuna indibaniselwano nezinye iiretardants zomlilo.

Ukusebenza:

• Kucetyiswa njenge-synergist ye-ATH okanye i-aluminium hypophosphite.

I-Aluminiyam Hypophosphite
Izinto eziluncedo:

• Ukusebenza okuphezulu, i-halogen-free, ukulayisha okuphantsi (10-20 phr).
• Uzinzo oluhle lwe-thermal, olufanelekileyo kwiimfuno eziphezulu zokubuyiswa komlilo.

Izinto ezingeloncedo:

• Iindleko eziphezulu.
• Ukuhambelana neenkqubo zelatex kufuna ukuqinisekiswa.

Ukusebenza:

• Ifanelekile kwimigangatho ephezulu yokulinda idangatye (umzekelo, UL94 V-0).
• Ingasetyenziswa yodwa okanye ngokudibeneyo.

I-MCA (iMelamine Cynurate)
Izinto eziluncedo:

• I-nitrogen esekelwe kwi-flame retardant, ukuxinzelela umsi.

Izinto ezingeloncedo:

• Ukusasazeka kakubi.
• Inokuphazamisana nogwebu.
• Ubushushu obuphezulu bokubola (~ 300 ° C), aluhambelani nokusetyenzwa kwelatex yobushushu obuphantsi.

Ukusebenza:

• Ayikhuthazwa njengento ephambili; ifuna ukuqinisekiswa kovavanyo.

II. Uqulunqo olucetyiswayo kunye neengcebiso zeNkqubo

Ulwakhiwo 1: ATH + Zinc Borate (Ukhetho loQoqosho)
Ukuqulunqwa:

• I-Aluminiyam Hydroxide (ATH): 30-40 phr
• I-Zinc Borate: 5-10 phr
• I-Dispersant (umzekelo, i-silane coupling agent): 1-2 phr (iphucula ukusasazeka)

Iimpawu:

• Iindleko eziphantsi, zihambelana nokusingqongileyo.
• Ifanelekile kwiimfuno eziqhelekileyo zokubuyiswa komlilo (umzekelo, UL94 HF-1).
• Inokunciphisa kancinci ukomelela kwesipontshi; Ukwandiswa kweVulcanization kuyafuneka.

Ukuqulunqwa kwe-2: I-Aluminiyam Hypophosphite + I-Zinc Borate (Ukhetho oluSebenza ngokuPhezulu)
Ukuqulunqwa:

• I-Aluminiyam Hypophosphite: 15-20 phr
• I-Zinc Borate: 5-8 phr
• Iplastiki yeplastiki (umzekelo, iparafini engamanzi): 2-3 phr (iphucula ukuqhubekeka)

Iimpawu:

• Ukusebenza kakuhle kwe-flame retadancy, ukulayisha okuphantsi.
• Ifanelekile kwiimeko zemfuno ephezulu (umzekelo, ukutshisa i-V-0).
• Ukuhambelana kwe-aluminium hypophosphite kunye novavanyo lweemfuno ze-latex.

Ulwakhiwo 3: ATH + Aluminiyam Hypophosphite (Ukhetho oluBalanced)
Ukuqulunqwa:

• I-Aluminiyam Hydroxide: 20-30 phr
• I-Aluminiyam Hypophosphite: 10-15 phr
• I-Zinc Borate: 3-5 phr

Iimpawu:

• Ukulinganisa iindleko kunye nokusebenza.
• Ukunciphisa ukuthembela kwi-flame retardant enye, ukunciphisa impembelelo kwiipropati ezibonakalayo.

III. Iingqwalasela zeNkqubo

Ukusasazeka:

• I-flame retardants kufuneka ibe phantsi kwi-≤5μm ukuphepha ukuchaphazela isakhiwo se-foam.
• Ukusasazwa kwangaphambili kwi-latex okanye kwisixhobo sokuxuba ngesantya esiphezulu kuyacetyiswa.

Iimeko zokunyanga:

• Lawula ubushushu bokunyanga (ngokuqhelekileyo yi-110-130 ° C ye-latex) ukunqanda ukubola kwangaphambi kwexesha leeretadants zomlilo.

Uvavanyo lokuSebenza:

• Iimvavanyo ezibalulekileyo: I-Oxygen Index (LOI), i-Vertical Burn (UL94), Ubuninzi, Ukuqina.
• Ukuba i-flame retardancy ayonelanga, ngokuthe ngcembe ukwandisa i-aluminium hypophosphite okanye i-ATH ratios.

IV. Iingcebiso ezongezelelweyo

Uvavanyo lwe-MCA:

• Ukuba uyazama, sebenzisa i-5-10 phr kwiibhetshi ezincinci ukujonga impembelelo yokufana kogwebu.

Izatifikethi zokusiNgqongileyo:

• Qinisekisa ukuba iiretardants ezikhethiweyo zomlilo zithobela i-RoHS/REACH yokuthumela ngaphandle.

Imixube yeSynergistic:

• Cinga ukongeza amanani amancinci e-nanoclay (2-3 phr) ukuphucula iziphumo zokuthintela i-char.
