PP V2 Flame Retardant Masterbatch Reference Foromo
Bakeng sa ho fihlela UL94 V2 flame retardancy ho PP (polypropylene) masterbatches, motsoako oa synergistic oa li-flame retardants oa hlokahala ha o ntse o boloka ts'ebetso ea ts'ebetso le thepa ea mochini. Ka tlase ke tlhahiso e ntlafalitsoeng e nang le litlhaloso:
I. Keletso ea Tlhahiso ea Base
Sebopeho sa Flame Retardant:
| Karolo | E ea kenya (wt%) | Tlhaloso ea Mosebetsi |
| PP Resin | 50-60% | Carrier resin (e khothaletsa boemo bo phahameng ba ho qhibiliha ha phallo, mohlala, MFI 20-30 g/10min) |
| Hypophosphite ea aluminium | 15-20% | Mohloli oa acid, o khothalletsa sebopeho sa char, botsitso bo botle ba mocheso bakeng sa ts'ebetso ea PP |
| Borate ea Zinc | 5-8% | Synergistic flame retardant, e hatella mosi le ho ntlafatsa ho lieha ha lelakabe la khase |
| Aluminium Hydrooxide e fetotsoeng holim'a sefahleho | 10-15% | Endothermic decomposition, e theola mocheso oa ho tuka (phekolo ea holim'a metsi, mohlala, silane coupling agent, e khothalelitsoe) |
| Dipentaerythritol (Di-PE) | 5-8% | Mohloli oa khabone, o hokahana le mohloli oa asiti ho theha char ea intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Mohloli oa khase (tlatsetso e khothalelitsoeng), e ntša likhase tse inert ho matlafatsa intumescence |
| Anti-Dripping Agent (PTFE) | 0.3-0.5% | E fokotsa ho rotha ho qhibiliha (ho ikhethela V2, kaha ho rotha ho lumelletsoe) |
| Antioxidant (1010/168) | 0.3-0.5% | E thibela ho senyeha ha mocheso oa oxidative nakong ea ts'ebetso |
| Lubricant (Zinc Stearate) | 0.5-1% | E ntlafatsa phallo ea ts'ebetso le ho hasana |
| 'Mala oa Carrier & Pigment | Joalo ka ha ho hlokahala | Khetha li-pigment tse mamellang mocheso o phahameng ho qoba ho ts'oaroa ha li-flame retardants |
II. Lintlha tsa Bohlokoa tsa Ntlafatso
- Synergistic Flame Retardant System
- Intumescent Flame Retardant (IFR):Aluminium hypophosphite (mohloli oa asiti) + Di-PE (mohloli oa carbon) + MPP (mohloli oa khase) o theha tsamaiso ea IFR, e etsang hore ho be le mocheso o thibelang mocheso ho thibela mocheso le oksijene.
- Zinc Borate Synergy:E sebetsana le aluminium hypophosphite ho etsa lera le sireletsang la galase, e matlafatsang ho lieha ha lelakabe la khase.
- Aluminium Hydrooxide e fetotsoeng:Phekolo ea bokaholimo e fokotsa ho lokolloa ha mongobo nakong ea ts'ebetso ha e ntse e fana ka ho bola ha endothermic ho theola mocheso oa mollo.
- Ts'ebetso le Tekanyo ea Ts'ebetso
- Kakaretso ea lelakabe retardant loading lokela ho laoloa ho35-45%ho qoba tahlehelo e kholo ea thepa ea mochini.
- Sebelisaresin e phahameng ea MFI PP (mohlala, PPH-Y40)ho ntlafatsa ho hasana ha masterbatch le ho fokotsa viscosity.
- Liteko & Litlhahiso tsa netefatso
- UL94 Vertical Burning Test:Etsa bonnete ba hore malakabe aa tima ka hare60 metsotsoanaka mor'a ho khantša habeli.
- Teko ea Mechini:Tsepamisa maikutlo ho matla a thata (≥20 MPa) le matla a tšusumetso (≥4 kJ/m²).
- Thermal Stability (TGA):Netefatsa mocheso oa ho bola ha lelakabe o tsamaisana le mefuta ea ts'ebetso ea PP (180–220°C).
III. Liphetoho tsa boikhethelo
- Bakeng sa ho Fokotsa Lelakabe ho Holimo (mohlala, V0):
- Eketsa aluminium hypophosphite ho25%, eketsa2% silicone(khatello ea mosi), le ho phahamisa PTFE ho0.8%.
- Lits'ebetso tse Ikemetseng Litšenyehelo:
- Fokotsa litaba tsa MPP mme o eketse aluminium hydroxide ka mokhoa o itekanetseng (etsa bonnete ba botsitso ba ts'ebetso).
IV. Lintlha Tse ka Sehloohong
- Tlhahiso ea Masterbatch:Pele ho kopanya li-retardants tsa lelakabe le resin ea carrier;"twin-screw extrusion" (180-210°C)e khothaletsoa.
- Ho omisa Aluminium Hydroxide:Omella ho110 ° C bakeng sa lihora tse 4ho thibela li-bubble nakong ea ts'ebetso.
- Di-PE/Aluminium Hypophosphite Ratio:Boloka1:2 ho ea ho 1:3bakeng sa ts'ebetso e nepahetseng ea ho theha char.
Ka mokhoa ona o ntlafalitsoeng oa sebopeho le ts'ebetso,UL94 V2 ho fokotseha ha lelakabee ka finyelloa ka mokhoa o tsitsitseng ha e ntse e boloka ts'ebetso ea ts'ebetso le botsitso ba mebala. Liteko tse nyane li khothaletsoa ho lokisoa hantle ho ipapisitsoe le liphetho tsa liteko.
