Reference flame retardant formulation for adhesives

Moralo oa sekhomaretsi oa sekhomaretsi o hloka ho hlophisoa ho latela mofuta oa sekhomaretsi (joalo ka epoxy resin, polyurethane, acrylic, joalo-joalo) le maemo a ts'ebeliso (joalo ka kaho, lisebelisoa tsa elektroniki, likoloi, joalo-joalo). Ka tlase ho na le likarolo tse tloaelehileng tsa sekhomaretsi sa lelakabe la retardant le mesebetsi ea tsona, tse koahelang tharollo ea mollo oa halogenated le halogen-free.

1. Melao-motheo ea Moqapi oa Sebopeho sa Adhesive Flame Retardant

• Bokhoni bo Phahameng: Kopana le UL 94 V0 kapa V2.
• Ho lumellana: Sehlahisoa sa mollo se lokela ho lumellana le lisebelisoa tsa motheo tsa sekhomaretsi ntle le ho ama ts'ebetso ea bonding.
• Botsoalle ba Tikoloho: Bea ka pele li-halogen-free flame retardants ho latela melao ea tikoloho.
• Tshebetso ea ho sebetsa: Sehlahisoa sa lelakabe ha sea lokela ho kena-kenana le mokhoa oa ho folisa kapa ho phalla ha sekhomaretsi.

2. Ho theha Sekhomaretsi sa Halogenated Flame Retardant

Li-halogenated flame retardants (mohlala, brominated) li sitisa tšebetso ea ketane ea ho tuka ka ho lokolla li-halogen radicals, tse fanang ka ts'ebetso e phahameng ea ho thibela mollo.

Likarolo tsa Tlhahiso:

• Sekhomaretsi Base Material: Epoxy resin, polyurethane, kapa acrylic.
• Brominated Flame Retardant: 10-20% (mohlala, decabromodiphenyl ether, brominated polystyrene).
• Antimony Trioxide (Setsebi sa Synergist): 3-5% (e ntlafatsa phello e thibelang mollo).
• Plasticizer: 1–3% (e ntlafatsa ho feto-fetoha ha maemo).
• Moemeli oa Phekolo: E khethiloe ho latela mofuta oa sekhomaretsi (mohlala, amine-based for epoxy resin).
• Solvent: Joalokaha ho hlokahala (ho fetola viscosity).

Litšobotsi:

• Melemo: Ts'ebetso e phahameng e thibelang lelakabe, palo e tlase ea tlatsetso.
• Mefokolo: E ka hlahisa likhase tse chefo nakong ea mollo; mathata a tikoloho.

3. Tlhahiso ea Sekhomaretsi sa Halogen-Free Flame Retardant

Li-halogen-free retardants (mohlala, phosphorus-based, nitrogen-based, kapa inorganic hydroxides) li sebetsa ka ho kopana le mocheso kapa ho theha lera le sireletsang, tse fanang ka ts'ebetso e ntle ea tikoloho.

Likarolo tsa Tlhahiso:

• Sekhomaretsi Base Material: Epoxy resin, polyurethane, kapa acrylic.
• Phosphorus-Based Flame Retardant: 10–15% (mohlala,ammonium polyphosphate APPkapa phosphorus e khubelu).
• Naetrojene-Thehiloeng Lelakabe Retardant: 5-10% (mohlala, melamine cyanrate MCA).
• Li-Inorganic Hydroxydes: 20-30% (mohlala, aluminium hydroxide kapa magnesium hydroxide).
• Plasticizer: 1–3% (e ntlafatsa ho feto-fetoha ha maemo).
• Moemeli oa Phekolo: E khethiloe ho latela mofuta oa sekhomaretsi.
• Solvent: Joalokaha ho hlokahala (ho fetola viscosity).

Litšobotsi:

• Melemo: E na le tikoloho, ha e na khase e chefo, e lumellanang le melao.
• Mefokolo: Ts'ebetso e tlase ea ho thibela lelakabe, palo e phahameng ea tlatsetso, e ka ama thepa ea mochini.

4. Lintlha tsa Bohlokoa ho Moralo oa Tlhahiso

• Lelakabe Retardant Khetho:
  • Halogenated: Ho sebetsa hantle haholo empa ho baka likotsi tsa tikoloho le bophelo bo botle.
  • Halogen-Free: Eco-friendly empa e hloka bongata bo boholo.
• Ho lumellana: Etsa bonnete ba hore sehlaseli sa lelakabe ha se bake delamination kapa ho fokotsa ts'ebetso ea bonding.
• Tshebetso ea ho sebetsa: Qoba ho kena-kenana le pheko le phallo.
• Tumellano ea Tikoloho: Khetha likhetho tse se nang halogen ho kopana le RoHS, REACH, joalo-joalo.

5. Likopo tse Tloaelehileng

• Kaho: Li-sealant tse thibelang mollo, li-adhesives tsa sebopeho.
• Tsa elektroniki: Likhomaretsi tsa li-circuit board encapsulation, li-adhesives conductive.
• Tsa makoloi: Li-adhesives tse khanyang, li-adhesives tse ka hare.

6. Litlhahiso tsa ho ntlafatsa ho theha

• Ho ntlafatsa ho Fokotsa Lelakabe:
  • Likopano tsa Synergistic (mohlala, halogen-antimony, phosphorus-nitrogen).
  • Li-nano flame retardants (mohlala, nano magnesium hydroxide kapa nano clay) ho ntlafatsa ts'ebetso le ho fokotsa palo ea tlatsetso.
• Ho ntlafatsa Thepa ea Mechini:
  • Li-tougheners (mohlala, POE kapa EPDM) ho ntlafatsa ho tenyetseha le ho hanyetsa matla.
  • Ho matlafatsa li-filler (mohlala, fiber ea khalase) ho eketsa matla le ho tiea.
• Phokotso ea Litšenyehelo:
  • Ntlafatsa likarolo tse thibelang malakabe ho fokotsa ts'ebeliso ha u ntse u fihlela litlhoko.
  • Khetha lisebelisoa tse bolokang chelete e ngata (mohlala, li-retardants tsa malapeng kapa tse tsoakiloeng).

7. Litlhoko tsa Tikoloho le Taolo

• Li-Halogenated Flame Retardants: E thibetsoe tlas'a RoHS, REACH, joalo-joalo; sebelisa ka hloko.
• Li-Halogen-Free Flame Retardants: E lumellana le melaoana; mokgoa o tlang.

8. Kakaretso

Meetso ea sekhomaretsi ea lelakabe la sekhomaretsi e lokela ho raloa ho ipapisitsoe le lits'ebetso tse ikhethileng le litlhoko tsa taolo, ho khetha lipakeng tsa likhetho tse se nang halogenated kapa halogen. Li-halogenated flame retardants li fana ka ts'ebetso e phahameng empa li beha likotsi tsa tikoloho, athe mefuta e meng e se nang halogen e sebetsa hantle empa e hloka likhakanyo tse phahameng. Ka ho ntlafatsa litlhophiso le lits'ebetso, likhomaretsi tse sebetsang hantle haholo, tse baballang tikoloho le tse bolokang chelete e ngata tse thibelang malakabe li ka ntlafatsoa bakeng sa liindasteri tsa kaho, tsa elektroniki, tsa likoloi le tse ling.
