Description
Foreliggende oppfinnelse angår nye polyolefiniske materialer egnet for fremstilling av selvs lukkende gjenstander. Nærmere bestemt angår oppfinnelsen materialer bestående av polymerer eller copolymerer av ethylen og/eller a-olefiner eller av polymerer av styren inneholdende" spesielle brannslukkende midler.
Forskjellige anvendbare fremgangsmåter til å gjore polymerene brannsikre er allerede kjent innen faget; disse fremgangsmåter er. hovedsakelig basert på tilsetning til polymerene av ter-misk ustabile halogenerte forbindelser hvLlke, som folge av varmen, spalter under dannelse av saltsyre eller hydrobromsyre.
Eksempler på slike halogenerte forbindelser er: klorerte paraffinvokser inneholdende fra 40 til 75 % klor, og klorerte eller bromerté fenoler.
Når halogenerte forbindelser av samme type som dé ovenfor angitte klorerte paraffinvokser eller klorerte eller bromerte fenoler tilsettes til polyethylenet eller polypropylenet, vil polymerens brennbarhet gjennomgå en nedsettelse som avhenger av mengden av tilstedeværende halogen i polymeren. For å oppnå en tilfredsstillende grad av ubrennbarhet er det imidlertid nodvendig med meget store mengder halogenerte forbindelser, generelt stdrre enn 30 vekt% i forhold til polymeren.
For å redusere mengden av halogenert additiv i polymeren er der også kjent å innfore en oxygenert antimonforbindelse av typen antimontrioxyd eller antimonoxyhalogenider.
Selvom kombinasjonen av antimontrioxyd + halogenert paraffin gir tilfredsstillende resultater med hensyn til de selvslukkende egenskaper de gir polymerene, er de ikke desto mindre slett ikke fri for relativt alvorlige ulemper. I realiteten må antimontrioxyd tilsettes til polymeren i mengder storre enn 10 vekt% og halogenert paraffin i en mengde på 15 - 30 vekt%, slik at den totale additivmengde (antimonforbindelse + halogenert pa-raff in) generelt blir mellom 30 og 35 vekt% i forhold til polymeren. Dette bevirker en sterk svekkelse av polymerens mekaniske egenskaper (bruddbelastning, konvensjonell flytegrense, hårdhet, elastisitet) korrosjon av det utstyr i hvilket behandlingen av materialene utføres og endelig en sterk utvikling av giftig røk og gasser i tilfelle av brann.
DE-utlegningsskrift 1.193.669 beskriver selvslukkende støpematerialer basert på en olefin- eller styren-polymer, hvilke som brannhemmende additiv inneholder (1) en klorfenylester av en alifatisk dicarboxylsyre, (2) et vismutoxyd eller sulfid, og eventuelt (3) en klorert paraffin.
Der er nu funnet et plastmateriale egnet for fremstilling av selvslukkende gjenstander og bestående av: (1) en polymer av ethylen og/eller a-olefiner eller en styren-polymer, (2) en vismutforbindelse i en andel som tilsvarer 0,5 - 5 vektdeler elementært vismut pr. 100 vektdeler plastmateriale, (3) en partielt halogenert polymer eller monomer organisk forbindelse som ved oppvarmning avspalter hydrogenhalogenid i en andel av 1 - 10 vektdeler pr. 100 vektdeler plastmateriale, og eventuelt (4) andre vanlige tilsetninger, såsom stabilisatorer, i de vanlige mengder, hvilket materiale er kjennetegnet ved at vismuthforbindelsen er vismathcarbonat.
Blant de ovenfor angitte delvis halogenerte forbindelser kan nevnes: klorerte paraffinvokser inneholdende fra 40 til 75 vekt% klor, klorert propylen, klorerte nafthelener, klorerte indener, klorerte polyfenyler slik som klorert terfenyl, tetra-klorfthalsyreanhydrid, klorerte polyfenoler slik som tetraklorert bisfenol A, klorerte polymerer slik som polyvinylklorid, polyvin-ylidenklorid, klorerte polyesterharpikser og klorerte gummier.
Vismuthforbindelsen anvendes i slike mengder at den gir et vismuthinnhold i polyolefinma terialet på mindre enn 5 vekt%, og nærmere bestemt mellom 0,5 og 3 vekt%. De delvis halogenerte forbindelser anvendes i en mengde mellom 1 og 10 vekt%, for-trinnsvis mellom 3 og 6 vekt%, basert på blandingen.
Det er også mulig å bibringe selvslukkende egenskaper til polyolefinene ved tilsetning av reaksjonsproduktet mellom vismuthforbindelsen og den delvis halogenerte forbindelse. I dette tilfelle bringes de to forbindelser til å omsettes i mengder svarende til de ovenfor angitte vektprosenter.
De erholdte materialer ekstruderes i konvensjonelle eks-trudere for å oppnå et granulert produkt som kan anvendes ved fremstilling av selvslukkende gjenstander, eller de kan anvendes for fremstilling av støpte gjenstander uten preliminær granuler-ing.
Som polyolefiner kan anvendes: HD- eller LD-polyethylen, isotaktisk eller hovedsakelig isotaktisk polypropylen, eventuelt modifisert med små mengder polymerisert ethylen, elastomere ethylen-propylencopolymerer, og styrenpolymerer.
De følgende eksempler illustrerer oppfinnelsen.
Eksempler 1- 18
De pulverformige bestanddeler, (polyolefin, vismuthforbindelse og delvis halogenert forbindelse}som var veiet på for-hånd, ble blandet i tørr tilstand i en 1 liters rota sjonskolbe i nitrogenatmosfære ved romtemperatur.
Den således erholdte blanding ble derefter ekstrudert i en DOLCI ekstruder (skrudiameter = 20 mm; lengde/diameterforhold = 23; rotasjonshastighet = 20 omdr./min) ved en temperatur på
190°C under dannelse av et granulært produkt som derefter ble anvendt for fremstilling av 3 mm tykke plater ved hjelp av en liten CARVER presse.
Den således fremstiHede plate ble undersdkt med hensyn til sin selvslukkende kapasitet ved måling av oxygenindeksen ifol-ge ASTM standard D-2863, som uttrykker de*, minimale oxygen i en oxygen/nitrogenblanding som er nodvendig for at proven skal brenne kontinuerlig.
Testene ble utfort under anvendelse av polypropylen med en isotaktisk indeks: på 95 som polyolef inet, CERECLOR 70 (et klorert paraffin med 70 % Cl), som den delvis halogenerte forbindelse, og de forbindelser som er oppfort i tabell I som vismuthforbindelsene.
Platen for hvilken oxygenindeksen ble bestemt ble frem-stillet ved å utgå fra 20O g av en blanding av:
Resultatene av forsdkene med de forskjellige vismuthfor-bindelser er oppfort i tabell I.
Eksempel 19
I en 0,5 liters rotasj onskolbe ble innfort 50 g "CERECLOR 70"og 10 g (Bi0)2C03, og denne blanding ble oppvarmet i et oljebad holdt ved 180°C. Fra kolben ble avgitt sure damper som ble fort bort av en nitrogenstrdm og fremkaldte blakking av en ba-riumhydroxydopplosning. Når efter to timer gasstrdmmen ikke len-ger blakket bariumhydratoppldsningen, ble oppvarmningen avsluttet og kolben fikk avkjoles til romtemperatur.
Derefter ble 6 g av det faste reaksjonsprodukt malt og blandet til 94 g polypropylen med en isotaktisk indeks på 95, hvorefter samme prosedyre som beskrevet i eksempler 1-18 ble fulgt. Efter ekstrudering og stopning ble erholdt en plate som hadde en oxygenindeks på 28,5.
Eksempler 20 - 22
Den samme fremgangsmåte som beskrevet i eksempler 1-18 ble fulgt med unntagelse av at polystyren ble anvendt i stedet for polypropylen og at støpetemperaturen var 160 i stedet for 180°C.
Testene ble utført under anvendelse av det basiske carb-onat (BiO) 2C03 301,1 vismuthforbindelse, og "Citex BC 26" (en alifatisk klorbromert forbindelse inneholdende 40 % Cl og 29 % Br), "Flammex 5 BP" (pentabromfenol) og "Cereclor 70" (klorert paraffin med 70 % innhold av Cl), som delvis halogenerte forbindelser.
Testresultatene er oppført i tabell II.
