Polypropylene (PP) Flame Retardant Masterbatch jẹ idapọ ifọkansi giga ti awọn retardants ina ati resini ti ngbe, ti a lo lati ṣe irọrun iyipada-ina ti awọn ohun elo PP. Ni isalẹ ni alaye PP ina retardant masterbatch agbekalẹ ati alaye:
I. Ipilẹ Tiwqn ti PP Flame Retardant Masterbatch
- Resini ti ngbe: Ni igbagbogbo PP, aridaju ibamu ti o dara pẹlu ohun elo ipilẹ.
- ina retardant: Halogenated tabi halogen-free, yan da lori awọn ibeere.
- Afọwọṣepọ: Ṣe ilọsiwaju idaduro ina (fun apẹẹrẹ, antimony trioxide).
- Olupinpin: Ṣe ilọsiwaju pipinka ti awọn retardants ina.
- Oloro: Imudara processing fluidity.
- Amuduro: Idilọwọ ibajẹ lakoko sisẹ.
II. Halogenated Flame Retardant PP Masterbatch agbekalẹ
Awọn idaduro ina halogenated (fun apẹẹrẹ, brominated) ni idapo pẹlu antimony trioxide nfunni ni ṣiṣe giga.
Apeere Ilana:
- Resini ti ngbe (PP): 40–50%
- Idaduro ina ti o bajẹ (fun apẹẹrẹ, decabromodiphenyl ether tabi polystyrene brominated): 30–40%
- Antimony trioxide (synergist): 5–10%
- Pipin (fun apẹẹrẹ, epo-eti polyethylene): 2–3%
- Oloro (fun apẹẹrẹ, kalisiomu stearate): 1–2%
- Antioxidant (fun apẹẹrẹ, 1010 tabi 168): 0.5–1%
Awọn Igbesẹ Ṣiṣe:
- Ṣaaju ki o to dapọ gbogbo awọn paati ni iṣọkan.
- Yo-dapọ lilo a ibeji-skru extruder ati pelletize.
- Ṣakoso iwọn otutu extrusion ni 180-220 °C.
Awọn abuda:
- Idaduro ina giga pẹlu ikojọpọ aropọ kekere.
- Le tu awọn gaasi oloro silẹ lakoko ijona.
- Dara fun awọn ohun elo pẹlu awọn ibeere ayika kekere.
III. Halogen-Free Ina Retardant PP Masterbatch agbekalẹ
Awọn idapada ti ko ni halogen (fun apẹẹrẹ, irawọ owurọ-, orisun nitrogen, tabi hydroxides inorganic) jẹ ọrẹ-aye ṣugbọn nilo awọn ikojọpọ giga.
Apeere Ilana:
- Resini ti ngbe (PP): 30–40%
- Idaduro orisun fosifọru (fun apẹẹrẹ, ammonium polyphosphate APP tabi irawọ owurọ pupa): 20–30%
- Idaduro orisun nitrojini (fun apẹẹrẹ, melamine cyanurate MCA): 10–15%
- Iṣuu magnẹsia hydroxide tabi aluminiomu hydroxide: 20-30%
- Pipin (fun apẹẹrẹ, epo-eti polyethylene): 2–3%
- Lubricant (fun apẹẹrẹ, zinc stearate): 1–2%
- Antioxidant (fun apẹẹrẹ, 1010 tabi 168): 0.5–1%
Awọn Igbesẹ Ṣiṣe:
- Ṣaaju ki o to dapọ gbogbo awọn paati ni iṣọkan.
- Yo-dapọ lilo a ibeji-skru extruder ati pelletize.
- Ṣakoso iwọn otutu extrusion ni 180-210 °C.
Awọn abuda:
- Eco-ore, ko si awọn gaasi majele lakoko ijona.
- Ikojọpọ aropo ti o ga julọ le ba awọn ohun-ini ẹrọ jẹ.
- Dara fun awọn ohun elo pẹlu awọn ajohunše ayika ti o muna.
IV. Key riro ni Formulation Design
- Ina retardant yiyan: Yan halogenated tabi halogen-ọfẹ ti o da lori aabo ina ti o nilo ati awọn ilana ayika.
- Ti ngbe resini ibamu: Gbọdọ jẹ ibamu pẹlu PP mimọ lati ṣe idiwọ delamination.
- Pipin: Dispersants ati lubricants rii daju isokan pinpin retardants.
- Iwọn otutu ti nṣiṣẹ: Yẹra fun ooru ti o pọju lati dena idibajẹ idaduro.
- Darí-ini: Awọn ikojọpọ afikun ti o ga le dinku iṣẹ ṣiṣe; ro awọn aṣoju toughening (fun apẹẹrẹ, POE tabi EPDM).
V. Awọn ohun elo Aṣoju
- Halogenated masterbatch: Electronics housings, onirin / kebulu.
- Halogen-ọfẹ masterbatch: Awọn inu inu ọkọ ayọkẹlẹ, awọn ohun elo ikole, awọn nkan isere ọmọde.
VI. Awọn iṣeduro iṣapeye
- Ṣe ilọsiwaju imuduro ina: Darapọ ọpọ retardants (fun apẹẹrẹ, irawọ owurọ-nitrogen amuṣiṣẹpọ).
- Mu darí-ini: Fi tougheners kun (fun apẹẹrẹ, POE/EPDM).
- Idinku iye owo: Mu awọn iwọn idaduro pada ki o yan awọn ohun elo ti o ni iye owo.
Nipa agbekalẹ onipin ati apẹrẹ sisẹ, awọn agbọnju ina PP le pade awọn iwulo ohun elo lọpọlọpọ.
Nitori awọn ilana ayika ati awọn aito ipese antimony trioxide, nọmba ti n pọ si ti awọn alabara n gba halogen-free irawọ owurọ-nitrogen ina retardants fun PP masterbatches. Fun apẹẹrẹ,TF-241le ṣee lo taara si awọn ọja PP ati awọn batches masterbatches, iyọrisi char-didara ominira ati awọn ipa intumescent laisi awọn afikun afikun. Lati mu awọn ohun-ini ẹrọ pọ si, awọn iye ti o yẹ ti awọn ṣiṣu ṣiṣu ati awọn aṣoju isọpọ ni a gbaniyanju.
