Polypropylene (PP) Flame Retardant Masterbatch reference formulations

Polypropylene (PP) Flame Retardant Masterbatch ndi chisakanizo chapamwamba cha zotchingira moto ndi utomoni wonyamulira, womwe umagwiritsidwa ntchito kupangitsa kuti zinthu za PP zikhale zosavuta kuzisintha. Pansipa pali tsatanetsatane wa PP flame retardant masterbatch ndi kufotokozera:

I. Basic Composition of PP Flame Retardant Masterbatch

• Chonyamulira utomoni: Nthawi zambiri PP, kuonetsetsa kuti ikugwirizana bwino ndi zinthu zoyambira.
• Moto retardant: Halogenated kapena halogen-free, osankhidwa malinga ndi zofunikira.
• Synergist: Imawonjezera kuchedwa kwa malawi (monga antimony trioxide).
• Wobalalitsa: Kupititsa patsogolo kubalalitsidwa kwa zoletsa moto.
• Mafuta: Kumawonjezera processing fluidity.
• Stabilizer: Zimalepheretsa kuwonongeka panthawi yokonza.

II. Halogenated Flame Retardant PP Masterbatch Formulation

Ma halogenated flame retardants (mwachitsanzo, brominated) kuphatikiza antimony trioxide amapereka mphamvu zambiri.

Kupanga Chitsanzo:

• Chonyamulira utomoni (PP): 40-50%
• Cholepheretsa moto cha brominated (mwachitsanzo, decabromodiphenyl ether kapena brominated polystyrene): 30-40%
• Antimony trioxide (synergist): 5-10%
• Dispersant (mwachitsanzo, sera ya polyethylene): 2-3%
• Mafuta (mwachitsanzo, calcium stearate): 1-2%
• Antioxidant (mwachitsanzo, 1010 kapena 168): 0.5-1%

Processing Masitepe:

1. Pre-kusakaniza zigawo zonse uniformly.
2. Sungunulani-sakanizani pogwiritsa ntchito twin-screw extruder ndi pelletize.
3. Sungani kutentha kwa extrusion pa 180-220 ° C.

Makhalidwe:

• Kuchedwa kwambiri kwa lawi ndi kutsitsa kwapang'onopang'ono kowonjezera.
• Itha kutulutsa mpweya wapoizoni panthawi yoyaka.
• Oyenera ntchito ndi otsika zofunika zachilengedwe.

III. Halogen-Free Flame Retardant PP Masterbatch Formulation

Zotsalira zopanda halogen (mwachitsanzo, phosphorous-, nitrogen-based, kapena inorganic hydroxides) ndizogwirizana ndi chilengedwe koma zimafunikira kudzaza kwambiri.

Kupanga Chitsanzo:

• Chonyamulira utomoni (PP): 30-40%
• Phosphorus-based retardant (mwachitsanzo, ammonium polyphosphate APP kapena phosphorous wofiira): 20-30%
• Nitrogen-based retardant (mwachitsanzo, melamine cyanrate MCA): 10-15%
• Magnesium hydroxide kapena aluminium hydroxide: 20-30%
• Dispersant (mwachitsanzo, sera ya polyethylene): 2-3%
• Mafuta (mwachitsanzo, zinc stearate): 1-2%
• Antioxidant (mwachitsanzo, 1010 kapena 168): 0.5-1%

Processing Masitepe:

1. Pre-kusakaniza zigawo zonse uniformly.
2. Sungunulani-sakanizani pogwiritsa ntchito twin-screw extruder ndi pelletize.
3. Sungani kutentha kwa extrusion pa 180-210 ° C.

Makhalidwe:

• Eco-ochezeka, palibe mpweya wapoizoni panthawi yoyaka.
• Kukweza kowonjezera kowonjezera kumatha kuwononga zida zamakina.
• Oyenera ntchito ndi malamulo okhwima zachilengedwe.

IV. Mfundo zazikuluzikulu pakupanga mapangidwe

• Kusankha koletsa moto: Sankhani ma halogenated kapena halogen-free kutengera kukana kofunikira ndi malamulo achilengedwe.
• Kugwirizana kwa utomoni wonyamulira: Iyenera kukhala yogwirizana ndi maziko a PP kuteteza delamination.
• Kubalalitsidwa: Dispersants ndi mafuta opangira mafuta amawonetsetsa kugawa kofanana kwa zotsalira.
• Processing kutentha: Pewani kutentha kwambiri kuti zisawole mochedwa.
• Zimango katundu: Zowonjezera zowonjezera zimatha kusokoneza magwiridwe antchito; ganizirani zolimbitsa thupi (mwachitsanzo, POE kapena EPDM).

V. Ntchito Zofananira

• Halogenated masterbatch: Nyumba zamagetsi, mawaya / zingwe.
• Halogen-free masterbatch: Zamkati zamagalimoto, zida zomangira, zoseweretsa za ana.

VI. Kukhathamiritsa Malangizo

• Wonjezerani kuchedwa kwa motoPhatikizani zotsalira zingapo (monga phosphorous-nitrogen synergy).
• Kupititsa patsogolo makina: Onjezani zolimbitsa thupi (mwachitsanzo, POE/EPDM).
• Kuchepetsa mtengo: Konzani ma retardant retardant ndikusankha zida zotsika mtengo.

Mwa kupanga koyenera komanso kamangidwe kake, ma masterbatches oyaka moto a PP amatha kukwaniritsa zosowa zosiyanasiyana.
Chifukwa cha malamulo a chilengedwe komanso kuchepa kwa ma antimony trioxide, makasitomala akuchulukirachulukira akugwiritsa ntchito ma halogen opanda phosphorous-nitrogen retardants a PP masterbatches. Mwachitsanzo,Mtengo wa TF-241Itha kugwiritsidwa ntchito mwachindunji kuzinthu za PP ndi ma masterbatches, kukwaniritsa zopanga zodziyimira pawokha komanso zopatsa mphamvu popanda zowonjezera. Kuti muwongolere magwiridwe antchito amakina, kuchuluka koyenera kwa ma plasticizer ndi ma coupling agents akulimbikitsidwa.
