Polypropylene (PP) Flame Retardant Masterbatch reference formulations

Polypropylene (PP) Flame Retardant Masterbatch musanganiswa wepamusoro-musanganiswa wezvinodzosa moto uye resin inotakura, inoshandiswa kurerutsa kuchinjika-kudzoreredza kwemurazvo wePP zvinhu. Pazasi pane yakadzama PP flame retardant masterbatch magadzirirwo uye tsananguro:

I. Basic Kuumbwa kwePP Flame Retardant Masterbatch

• Carrier resin: Kazhinji PP, kuve nechokwadi kuenderana kwakanaka nehwaro zvinhu.
• Flame retardant: Halogenated kana halogen-isina, yakasarudzwa zvichienderana nezvinodiwa.
• Synergist: Inowedzera kunonoka kwemurazvo (semuenzaniso, antimony trioxide).
• Dispersant: Inovandudza kupararira kwezvinodzosa moto.
• Lubricant: Inosimudzira kugadzirisa fluidity.
• Stabilizer: Inodzivirira kusvibiswa panguva yekugadzirisa.

II. Halogenated Flame Retardant PP Masterbatch Kugadzira

Halogenated flame retardants (semuenzaniso, brominated) yakasanganiswa neantimony trioxide inopa kushanda kwepamusoro.

Muenzaniso Formulation:

• Inotakura resin (PP): 40-50%
• Brominated flame retardant (semuenzaniso, decabromodiphenyl ether kana brominated polystyrene): 30–40%
• Antimony trioxide (synergist): 5-10%
• Dispersant (semuenzaniso, polyethylene wax): 2-3%
• Lubricant (semuenzaniso, calcium stearate): 1-2%
• Antioxidant (semuenzaniso, 1010 kana 168): 0.5–1%

Processing Matanho:

1. Pre-kusanganisa zvose zvikamu zvakafanana.
2. Melt-blend uchishandisa twin-screw extruder uye pelletize.
3. Dzora tembiricha yeextrusion pa180-220°C.

Hunhu:

• High flame retadancy ine low additive loading.
• Inogona kuburitsa magasi ane chepfu panguva yekupisa.
• Inokodzera maapplication ane yakaderera ezvakatipoteredza zvinodiwa.

III. Halogen-Yemahara Flame Retardant PP Masterbatch Magadzirirwo

Halogen-isina retardants (semuenzaniso, phosphorus-, nitrogen-based, kana inorganic hydroxides) ino-eco-friendly asi inoda kurodha zvakanyanya.

Muenzaniso Formulation:

• Inotakura resin (PP): 30-40%
• Phosphorus-based retardant (semuenzaniso, ammonium polyphosphate APP kana tsvuku phosphorus): 20-30%
• Nitrogen-based retardant (semuenzaniso, melamine cyanurate MCA): 10-15%
• Magnesium hydroxide kana aluminium hydroxide: 20-30%
• Dispersant (semuenzaniso, polyethylene wax): 2-3%
• Lubricant (semuenzaniso, zinc stearate): 1-2%
• Antioxidant (semuenzaniso, 1010 kana 168): 0.5–1%

Processing Matanho:

1. Pre-kusanganisa zvose zvikamu zvakafanana.
2. Melt-blend uchishandisa twin-screw extruder uye pelletize.
3. Dzora tembiricha yeextrusion pa180-210°C.

Hunhu:

• Eco-hushamwari, hapana magasi ane muchetura panguva yekupisa.
• Kuwedzera kwekuwedzera kurodha kunogona kukanganisa ma mechanical properties.
• Inokodzera maapplication ane akasimba ezvakatipoteredza zviyero.

IV. Mafungiro Akakosha muKugadzira Dhizaini

• Kusarudzwa kwemoto unodzoreredza: Sarudza halogenated kana halogen-isina zvichibva pane inodiwa murazvo kuramba uye mirairo yezvakatipoteredza.
• Carrier resin kuenderana: Inofanirwa kuenderana ne base PP kudzivirira delamination.
• Kupararira: Dispersants uye lubricant inova nechokwadi chekugovera yunifomu yemaretardants.
• Processing tembiricha: Dzivisa kupisa kwakanyanya kudzivirira kuparara kusingadzoreki.
• Mechanical properties: High additive loadings inogona kukanganisa kushanda; funga toughening agents (semuenzaniso, POE kana EPDM).

V. Typical Applications

• Halogenated masterbatch: Electronics dzimba, waya / tambo.
• Halogen-isina masterbatch: Zvemukati zvemotokari, zvekuvaka, matoyi evana.

VI. Optimization Recommendations

• Wedzera kunonoka kwemoto: Batanidza akawanda retardants (semuenzaniso, phosphorus-nitrogen synergy).
• Vandudza michina zvinhu: Wedzera tougheners (semuenzaniso, POE/EPDM).
• Kuderedza mutengo:Onesa retardant ratios uye sarudza inodhura-inoshanda zvinhu.

Nekunzwisisa kuumbwa uye kugadzirisa dhizaini, PP murazvo unodzoreredza masterbatches anogona kusangana nemhando dzakasiyana dzekushandisa.
Nekuda kwemirau yezvakatipoteredza uye kushomeka kweantimony trioxide, nhamba iri kuwedzera yevatengi vari kutora halogen-isina phosphorus-nitrogen flame retardants yePP masterbatches. Semuyenzaniso,TF-241inogona kuiswa zvakananga kune zvigadzirwa zvePP uye masterbatches, kuwana yakazvimirira char-kuumba uye intumescent mhedzisiro pasina zvimwe zvinowedzera. Kuti uwedzere zvivakwa zvemuchina, huwandu hwakakodzera hwemaplasticizers uye coupling agents zvinokurudzirwa.
