Ukwenziwa kwereferensi ye-halogen-free flame retardant for water-based acrylic adhesives electronic adhesives
Kwiinkqubo ze-acrylic ezisekelwe emanzini, iimali ezongeziweyo ze-aluminium hypophosphite (AHP) kunye ne-zinc borate (ZB) kufuneka zigqitywe ngokusekelwe kwiimfuno ezithile zesicelo (ezifana ne-flame retardancy rating, ubukhulu be-coating, iimfuno zokusebenza komzimba, njl.) kunye nemiphumo yazo ye-synergistic. Apha ngezantsi kukho iingcebiso ngokubanzi kunye noluhlu lweereferensi:
I. Isiseko soMyinge woMyinge weeMyinge ezibhekiselele
Itheyibhile: IiNgcaciso ezicetyiswayo zeFlame Retardant kunye neeNkcazo
| Uhlobo lweFlame Retardant | Udibaniso olucetyiswayo (wt%) | Inkcazo |
| IAluminiyam Hypophosphite (AHP) | 5%~20% | i-phosphorus-based-flame retardant; ibhalansi i-flame retardancy performance kunye nokuhambelana kwenkqubo (iimali ezigqithisileyo zinokuchaphazela iimpawu zoomatshini). |
| IZinc Borate (ZB) | 2%~10% | Isixhasi se-Synergistic; inokunciphisa ukongezwa okupheleleyo xa kudityaniswa ne-AHP (imilinganiselo ephezulu efunekayo xa isetyenziswa yodwa). |
II. UkuPhuculwa kweMilinganiselo yeCompound
- Imilinganiselo yeCompound eqhelekileyo:
- AHP:ZB = 2:1 ~ 4:1(umz., 15% AHP + 5% ZB, iyonke 20%).
- Lungisa umlinganiselo ngokomfuniselo, umzekelo:
- Imfuno ephezulu yokubuyiswa komlilo:AHP 15% ~ 20%, ZB 5% ~ 8%.
- Iimpawu zomzimba ezilungelelanisiweyo:AHP 10% ~ 15%, ZB 3% ~ 5%.
- Iziphumo ze-Synergistic:
- I-zinc borate yongeza ukusilela komlilo ngoku:
- Ukuzinzisa ukubunjwa kwe-char (isebenzisana ne-aluminium phosphate eveliswa yi-AHP).
- Ukukhulula amanzi abophekileyo ukufunxa ubushushu kunye nokuhlambulula iigesi ezinokutsha.
III. Amanyathelo oQinisekiso loMfuniselo
- Uvavanyo lweNyathelo:
- Uvavanyo lomntu ngamnye:Okokuqala uvavanya i-AHP (5% ~ 20%) okanye i-ZB (5% ~ 15%) ngokwahlukileyo kwi-flame retardancy (UL-94, LOI) kunye nokusebenza kokugubungela (ukubambelela, ukuqina, ukuxhathisa kwamanzi).
- Ulungiselelo oludityanisiweyo:Emva kokukhetha isixa se-AHP esisisiseko, yongeza ngokunyuka i-ZB (umzekelo, i-3% ukuya kwi-8% xa i-AHP iyi-15%) kwaye ugcine uphuculo kwi-flame retardancy kunye nemiphumo emibi.
- Iimpawu eziphambili zokuSebenza:
- Ukuncipha komlilo:I-LOI (ithagethi ≥28%), i-UL-94 yokukala (V-0/V-1), ukuxinana komsi.
- Iimpawu ezibonakalayo:Ukubunjwa kwefilimu, ukubambelela (ASTM D3359), ukumelana kwamanzi (akukho delamination emva kokucwiliswa kwe-48h).
IV. Iingqwalasela ezingundoqo
- Uzinzo lokusasazwa:
- I-AHP i-hygroscopic-yomile kwangaphambili okanye sebenzisa izinto ezahlukeneyo eziguquliwe.
- Sebenzisa i-dispersants (umzekelo, i-BYK-190, i-TEGO Dispers 750W) ukuphucula ukufana kunye nokuthintela ukuchithwa kwentlenga.
- Ukuhambelana kwe-pH:
- Iinkqubo ze-acrylic ezisekelwe emanzini zihlala zine-pH ye-8-9; qinisekisa ukuba i-AHP kunye ne-ZB zihlala zizinzile (ukuphepha i-hydrolysis okanye ukubola).
- Ukuthotyelwa koMgaqo:
- I-AHP kufuneka ihlangabezane neemfuno ze-RoHS ezingena-halogen; I-ZB kufuneka isebenzise amabanga asezantsi e-heavy-metal angacocekanga.
V. Izisombululo ezizezinye okanye ezongezelelweyo
- I-Melamine Polyphosphate (MPP):Ingaphucula ngakumbi ukubuyiswa komlilo xa kudityaniswa ne-AHP (umzekelo, i-10% ye-AHP + 5% MPP + 3% ZB).
- Nano Flame Retardants:I-Nano-grade ZB (ukongezwa kuncitshiswe kwi-1% ~ 3%) okanye i-hydroxides ephindwe kabini (LDH) kwimiphumo ephuculweyo yokuthintela.
VI. Isishwankathelo Iingcebiso
- Ukuqala ukwakhiwa:I-AHP 10% ~ 15% + ZB 3% ~ 5% (iyonke 13% ~ 20%), uze ulungise.
- Indlela yokuqinisekisa:Vavanya iisampuli ezincinci ze-LOI kunye ne-UL-94 ngelixa uvavanya iipropati zoomatshini.
