Halogen-isina murazvo retardant referensi referensi yemvura-based acrylic electronic adhesives
Mumvura-based acrylic masisitimu, huwandu hwekuwedzera hwealuminium hypophosphite (AHP) uye zinc borate (ZB) hunofanirwa kutariswa zvichienderana nezvinodiwa zvekushandisa (senge flame retardancy rating, ukobvu hwekupfeka, zvinodiwa zvemuviri, nezvimwewo) uye yavo synergistic mhedzisiro. Pazasi pane zvakajairwa kurudziro uye referenzi siyana:
I. Baseline Addition Amounts Reference
Tafura: Yakakurudzirwa Flame Retardant Additions uye Tsananguro
| Flame Retardant Type | Inokurudzirwa Kuwedzera (wt%) | Tsanangudzo |
| Aluminium Hypophosphite (AHP) | 5%~20% | Phosphorus-based flame retardant; balance flame retardancy performance nekuenderana nesystem (yakawandisa mari inogona kukanganisa ma mechanic properties). |
| Zinc Borate (ZB) | 2%~10% | Synergistic enhancer; inogona kuderedza kuwedzera kwese kana yasanganiswa neAHP (yepamusoro inodiwa kana ikashandiswa yega). |
II. Optimization yeCompound Ratios
- Typical Compound Ratios:
- AHP:ZB = 2:1 ~ 4:1(semuenzaniso, 15% AHP + 5% ZB, yakazara 20%).
- Rongedza reshiyo nekuyedza, semuenzaniso:
- High flame retadancy inoda:AHP 15% ~ 20%, ZB 5% ~ 8%.
- Balanced physical properties:AHP 10% ~ 15%, ZB 3% ~ 5%.
- Synergistic Effects:
- Zinc borate inowedzera kunonoka kwemurazvo ne:
- Kudzikamisa char kuumbwa (kudyidzana nealuminium phosphate inogadzirwa neAHP).
- Kuburitsa mvura yakasungwa kuti itore kupisa uye kuderedza magasi anobvira.
III. Kuedza Kusimbisa Matanho
- Stepwise Testing:
- Kuedza kwega:Kutanga ongorora AHP (5% ~ 20%) kana ZB (5% ~ 15%) zvakasiyana nekuda kwekunonoka kwemurazvo (UL-94, LOI) uye kuita kwekuputira (kunamatira, kuoma, kusagadzikana kwemvura).
- Compound optimization:Mushure mekusarudza huwandu hwekutanga hweAHP, wedzera ZB (semuenzaniso, 3% kusvika 8% apo AHP iri 15%) uye ona kuvandudzwa kwekunonoka kwemurazvo nemhedzisiro.
- Key Performance Indicators:
- Flame retadancy:LOI (chinangwa ≥28%), UL-94 rating (V-0/V-1), hutsi hwehutsi.
- Zvinhu zvenyama:Kuumbwa kwemafirimu, kunamatira (ASTM D3359), kuramba kwemvura (hapana delamination mushure mekunyudzwa kwe48h).
IV. Pfungwa Huru
- Dispersion Stability:
- AHP ndeye hygroscopic - isati yaoma kana kushandisa pamusoro-yakagadziridzwa zvakasiyana.
- Shandisa zvinoparadzira (semuenzaniso, BYK-190, TEGO Dispers 750W) kuvandudza kufanana uye kudzivirira sedimentation.
- pH kuenderana:
- Mvura-based acrylic systems inowanzova ne pH ye8-9; chengetedza AHP neZB zvinoramba zvakagadzikana (kudzivisa hydrolysis kana kuora).
- Regulatory Compliance:
- AHP inofanirwa kusangana ne halogen-isina RoHS zvinodiwa; ZB inofanira kushandisa yakaderera-heavy-metal tsvina mamakisi.
V. Alternative or Supplemental Solutions
- Melamine Polyphosphate (MPP):Inogona kuwedzera kunonoka kwemoto kana yasanganiswa neAHP (semuenzaniso, 10% AHP + 5% MPP + 3% ZB).
- Nano Flame Retardants:Nano-giredhi ZB (wedzero yakaderedzwa kusvika 1% ~ 3%) kana akaturikidzana kaviri hydroxides (LDH) yekuvandudza zvipingamupinyi mhedzisiro.
VI. Summary Recommendations
- Kutanga kugadzirwa:AHP 10% ~ 15% + ZB 3% ~ 5% (yakazara 13% ~ 20%), wozogadzirisa.
- Validation nzira:Edzai madiki-scale samples eLOI uye UL-94 uchiongorora michina zvivakwa.
