Formulation Shanduko yeHalogen-Yemahara Flame Retardant PVC Leather

Nhanganyaya

Mutengi anogadzira ganda rePVC rinodzoreredza moto uye rakamboshandiswa antimony trioxide (Sb₂O₃). Ivo zvino vavariro yekubvisa Sb₂O₃ uye chinja kune halogen-isina moto retardants. Ikozvino kuumbwa kunosanganisira PVC, DOP, EPOXY, BZ-500, ST, HICOAT-410, uye antimony. Kuchinja kubva kune antimony-based PVC dehwe kuumbwa kune halogen-isina murazvo-retardant system inomiririra yakakosha tekinoroji kusimudzira. Kuchinja uku hakungoenderane chete nekuwedzera kuomesera mirau yezvakatipoteredza (semuenzaniso, RoHS, REACH) asi zvakare inosimudzira chigadzirwa "girinhi" mufananidzo uye kukwikwidza kwemusika.

Matambudziko Anokosha

  1. Kurasika kweSynergistic Effect:
    • Sb₂O₃ haisi murazvo wakasimba wekudzoreredza uri woga asi unoratidza zvakanakisa synergistic murazvo-retardant mhedzisiro ine chlorine muPVC, inovandudza zvakanyanya kushanda zvakanaka. Kubvisa antimony kunoda kutsvaga imwe halogen-isina system inodzokorora iyi synergy.
  2. Flame Retardancy Efficiency:
    • Halogen-isina murazvo retardants kazhinji inoda kurodha yakakwirira kuti iwane yakaenzana mirazvo-inodzosa mirazvo (semuenzaniso, UL94 V-0), iyo inogona kukanganisa michina zvivakwa (kupfava, kusimba kwesimba, kurebesa), kugadzirisa mashandiro, uye mutengo.
  3. PVC Leather Hunhu:
    • PVC dehwe rinoda kupfava kwakanyanya, kunzwa kweruoko, kupera kwepamusoro (embossing, gloss), kuramba mamiriro ekunze, kuramba kutama, uye kudzika-tembiricha kuchinjika. Iyo nyowani yekuumbwa inofanirwa kuchengetedza kana kunyatsoenderana zvivakwa izvi.
  4. Processing Performance:
    • Yakakwira kurodha yehalogen-isina mafirita (semuenzaniso, ATH) inogona kukanganisa kunyungudika kuyerera uye kugadzikana kwekugadzirisa.
  5. Zvinotarisirwa Mutengo:
    • Mamwe emhando yepamusoro-yemahara halogen-isina murazvo retardants anodhura, zvinoda chiyero pakati pekuita uye mutengo.

Kusarudzwa Strategy yeHalogen-Yemahara Flame Retardant Systems (yePVC Artificial Dehwe)

1. Primary Flame Retardants - Metal Hydroxides

  • Aluminium Trihydroxide (ATH):
    • Yakawanda, inodhura-inoshanda.
    • Mechanism: Endothermic decomposition (~ 200 ° C), ichibudisa mhute yemvura kuti inyungudze magasi anopisa uye okisijeni paunenge uchigadzira denga rekudzivirira.
    • Drawbacks: Kuderera kwekuita, kurodha kwakanyanya kunodiwa (40-70 phr), kunoderedza zvakanyanya kupfava, kurebesa, uye processability; decomposition tembiricha yakaderera.
  • Magnesium Hydrooxide (MDH):
    • Yepamusoro decomposition tembiricha (~ 340°C), inonyatsokodzera PVC processing (160–200°C).
    • Drawbacks: Zvakafanana kurodha yakakwirira (40-70 phr) inodiwa; mutengo wakakwira zvishoma pane ATH; inogona kunge iine hunyoro hwepamusoro.

Nzira:

  • Sarudze MDH kana ATH/MDH musanganiswa (semuenzaniso, 70/30) kuenzanisa mutengo, kugadzirisa tembiricha kuchinjika, uye kunonoka kwemurazvo.
  • Yepamusoro-yakagadziriswa (semuenzaniso, silane-yakabatana) ATH/MDH inovandudza kuenderana nePVC, inoderedza kuparara kwemidziyo, uye inowedzera kunonoka kwemurazvo.

2. Flame Retardant Synergists

Kuti uderedze kurodha kwekutanga kwemoto uye kugadzirisa mashandiro, ma synergists akakosha:

  • Phosphorus-Nitrogen Flame Retardants: Yakanakira halogen-isina PVC masisitimu.
    • Ammonium Polyphosphate (APP): Inosimudzira charring, ichigadzira intumescent insulating layer.
      • Cherechedza: Shandisa magiredhi anodzivirira kupisa kwepamusoro (semu, Phase II, > 280 ° C) kudzivirira kuora panguva yekugadzirisa. Mamwe maAPP anogona kukanganisa kujeka uye kuramba kwemvura.
    • Aluminium Diethylphosphinate (ADP): Yakanyanya kushanda, yakaderera kurodha (5-20 phr), kuderera kunokanganisa zvivakwa, kugadzikana kwakanaka kwekupisa.
      • Drawback: Mutengo wepamusoro.
    • Phosphate Esters (semuenzaniso, RDP, BDP, TCPP): Inoshanda sepurasitiki inodzoreredza moto.
      • Zvakanakira: Dual basa (plasticizer + flame retardant).
      • Cons: Mamolekoro maduku (eg, TCPP) anogona kutama / kushanduka; RDP/BDP ine yakaderera plasticizing kunyatsoshanda pane DOP uye inogona kuderedza yakaderera-tembiricha kuchinjika.
  • Zinc Borate (ZB):
    • Yakaderera-mutengo, multifunctional (inodzoreredza murazvo, inodzvinyirira utsi, mutsigiri wechar, anti-dripping). Inopindirana zvakanaka neATH/MDH uye phosphorus-nitrogen masisitimu. Yakajairika kurodha: 3–10 phr.
  • Zinc Stanate/Hydroxy Stanate:
    • Zvakanakisa zvinodzvinyirira utsi uye murazvo unodzoreredza synergists, kunyanya kune chlorine-ine ma polymers (semuenzaniso, PVC). Inogona kutsiva chikamu cheantimony's synergistic role. Yakajairika kurodha: 2–8 phr.
  • Molybdenum Compounds (semuenzaniso, MoO₃, Ammonium Molybdate):
    • Zvipfungaidzo zvehutsi zvakasimba zvine murazvo unodzoreredza synergy. Yakajairika kurodha: 2-5 phr.
  • Nano Fillers (semuenzaniso, Nanoclay):
    • Yakaderera loadings (3-8 phr) inovandudza moto retardancy (char formation, kuderedza kupisa kusunungurwa kwehuwandu) uye michina yemagetsi. Kupararira kwakakosha.

3. Kusvuta Kusvuta

PVC inogadzira utsi hunorema panguva yekupisa. Halogen-isina kuumbwa kazhinji inoda kudzvanywa kweutsi. Zinc borate, zinc stannate, uye molybdenum makomisheni isarudzo dzakanakisa.

Yakakurudzirwa Halogen-Yemahara Flame Retardant Formulation (Inobva pane Mutengi Yekutanga Magadzirirwo)

Chinangwa: Wana UL94 V-0 (1.6 mm kana kukora) uchichengetedza kupfava, kugadzirisika, uye zvakakosha zvivakwa.

Mafungiro:

  • Magadzirirwo ekutanga:
    • DOP: 50-70 phr (plasticizer).
    • ST: Zvichida stearic acid (lubricant).
    • HICOAT-410: Ca/Zn stabilizer.
    • BZ-500: Zvichida mafuta / kugadzirisa rubatsiro (kusimbisa).
    • EPOXY: Epoxidized soybean mafuta (co-stabilizer/plasticizer).
    • Antimony: Sb₂O₃ (kubviswa).

1. Yakakurudzirwa Formulation Framework (per 100 phr PVC resin)

  1. Pilot & Production: Mushure mekugadzirisa lab, ita miyedzo yekutyaira kuti uone kugadzikana, kuenderana, uye mutengo. Wedzera kumusoro chete mushure mekusimbiswa.

Mhedziso

Kuchinja kubva kuantimony-yakavakirwa kuenda kune halogen-isina murazvo-inodzoreredza PVC dehwe zvinogoneka asi zvinoda kurongeka kwakarongeka. Nzira yepakati inobatanidza simbi hydroxides (zvichida pamusoro-yakabatwa MDH), phosphorus-nitrogen synergists (APP kana ADP), uye multifunctional utsi suppressants (zinc borate, zinc stannate). Panguva imwe chete, optimization plasticizers, stabilizers, lubricant, uye kugadzirisa aids kwakakosha.

Makiyi Ekubudirira:

  1. Tsanangura zvinangwa zvakajeka uye zvipingaidzo (kudzoserwa kwemoto, zvivakwa, mutengo).
  2. Sarudza yakasimbiswa halogen-isina murazvo retardants (pamusoro-yakagadziriswa mafirita, yakakwirira-temp APP).
  3. Ita zvakaomesesa lab yekuyedza (kudzoreredza moto, zvivakwa, kugadzirisa).
  4. Ita shuwa kusanganisa yunifomu uye kuenderana kwemaitiro.
