Polypropylene (PP) Flame Retardant Masterbatch yog qhov sib xyaw ua ke ntawm cov nplaim hluav taws kub thiab cov cab cab, siv los ua kom yooj yim rau kev hloov pauv cov nplaim hluav taws kub ntawm cov ntaub ntawv PP. Hauv qab no yog cov ncauj lus kom ntxaws PP nplaim retardant masterbatch tsim thiab piav qhia:
I. Basic Composition ntawm PP Nplaim Retardant Masterbatch
- Carrier cob: Feem ntau PP, ua kom muaj kev sib raug zoo nrog cov khoom siv hauv paus.
- Nplaim retardant: Halogenated lossis halogen-dawb, xaiv raws li qhov yuav tsum tau ua.
- Synergist: Txhim kho cov nplaim hluav taws xob (xws li antimony trioxide).
- Dispersant: Txhim kho cov dispersion ntawm nplaim retardants.
- Lubricant: Txhim kho cov txheej txheem fluidity.
- Stabilizer: Tiv thaiv kev degradation thaum ua.
II. Halogenated Nplaim Retardant PP Masterbatch Formulation
Halogenated nplaim retardants (xws li, brominated) ua ke nrog antimony trioxide muab kev ua haujlwm siab.
Piv txwv Formulation:
- Carrier cob (PP): 40-50%
- Brominated nplaim retardant (xws li decabromodiphenyl ether los yog brominated polystyrene): 30-40%
- Antimony trioxide (Synergist): 5-10%
- Dispersant (piv txwv li, polyethylene wax): 2-3%
- Lubricant (piv txwv li, calcium stearate): 1-2%
- Antioxidant (piv txwv li, 1010 lossis 168): 0.5-1%
Cov kauj ruam ua:
- Pre-mix tag nrho cov Cheebtsam uniformly.
- Melt-blend siv ib tug ntxaib-ntsia hlau extruder thiab pelletize.
- Tswj extrusion kub ntawm 180-220 ° C.
Yam ntxwv:
- High nplaim retardancy nrog tsawg additive loading.
- Tej zaum yuav tso cov pa phem thaum combustion.
- Haum rau cov ntawv thov uas tsis tshua muaj kev xav tau ib puag ncig.
III. Halogen-Free Flame Retardant PP Masterbatch Formulation
Halogen-free retardants (piv txwv li, phosphorus-, nitrogen-based, los yog inorganic hydroxides) yog eco-friendly tab sis yuav tsum tau loading ntau dua.
Piv txwv Formulation:
- Carrier cob (PP): 30-40%
- Phosphorus-based retardant (piv txwv li, ammonium polyphosphate APP lossis liab phosphorus): 20-30%
- Nitrogen-based retardant (piv txwv li, melamine cyanurate MCA): 10-15%
- Magnesium hydroxide lossis aluminium hydroxide: 20-30%
- Dispersant (piv txwv li, polyethylene wax): 2-3%
- Lubricant (xws li zinc stearate): 1-2%
- Antioxidant (piv txwv li, 1010 lossis 168): 0.5-1%
Cov kauj ruam ua:
- Pre-mix tag nrho cov Cheebtsam uniformly.
- Melt-blend siv ib tug ntxaib-ntsia hlau extruder thiab pelletize.
- Tswj extrusion kub ntawm 180-210 ° C.
Yam ntxwv:
- Eco-phooj ywg, tsis muaj tshuaj lom gases thaum combustion.
- Kev thauj khoom ntau dua tuaj yeem ua rau cov khoom siv kho tshuab tsis zoo.
- Haum rau cov ntawv thov nrog cov qauv nruj ib puag ncig.
IV. Cov ntsiab lus tseem ceeb hauv kev tsim qauv
- Nplaim retardant xaiv: Xaiv cov halogenated lossis halogen-dawb raws li qhov xav tau ntawm cov nplaim taws thiab cov kev cai ib puag ncig.
- Carrier cob compatibility: Yuav tsum tau sib haum nrog lub hauv paus PP los tiv thaiv delamination.
- Dispersion: Dispersants thiab lubricants kom tsis tu ncua kev faib tawm ntawm retardants.
- Ua haujlwm kub: Tsis txhob muaj cua sov ntau dhau los tiv thaiv retardant decomposition.
- Mechanical zog: Siab additive loadings yuav degrade kev ua tau zoo; xav txog cov tshuaj toughening (piv txwv li, POE lossis EPDM).
V. Cov ntawv thov ib txwm
- Halogenated masterbatch: Electronics vaj tse, xov hlau / cables.
- Halogen-dawb masterbatch: Automotive interiors, siv cov khoom siv, cov khoom ua si menyuam yaus.
VI. Optimization Cov lus pom zoo
- Txhim khu nplaim retardancy: Muab ntau yam retardants (piv txwv li, phosphorus-nitrogen synergy).
- Txhim kho cov khoom siv kho tshuab: Ntxiv tougheners (piv txwv li, POE/EPDM).
- Kev txo nqi: Optimize retardant ratios thiab xaiv cov khoom siv zoo.
Los ntawm kev tsim qauv tsim nyog thiab tsim qauv, PP nplaim hluav taws xob ua haujlwm tuaj yeem ua tau raws li ntau hom kev thov.
Vim yog cov kev cai ib puag ncig thiab antimony trioxide cov khoom tsis txaus, ntau tus neeg siv khoom tau txais cov halogen-dawb phosphorus-nitrogen nplaim retardants rau PP masterbatches. Piv txwv li,TSI-241tuaj yeem siv ncaj qha rau PP cov khoom thiab masterbatches, ua tiav kev ywj pheej char-forming thiab intumescent teebmeem yam tsis muaj cov khoom ntxiv. Txhawm rau txhim kho cov khoom siv kho tshuab kom zoo, cov khoom tsim nyog ntawm plasticizers thiab coupling agents raug pom zoo.
