Description
Lakk for overtrekning av innsiden av fortinnede blikkbokser, spesielt hermetikkbokser.
Foreliggende oppfinnelse angår lakker for overtrekning av innsiden av fortinnede blikkbokser, spesielt hermetikkbokser.
Det er kjent at termisk spaltning yy proteiner <y>v »riimalsk eller vegetabilsk opprinnelse forer til dannelse <y>v forskjellige sulfurerte produkter, spesielt merca.otaner og hydrogensulfid. Dette skjer spesielt under steriliseringen av pro teinnoidige næringsmidler anbragt i fortinnede pakninger. Tinnet som er til-stede på overflaten av me ta'1 I blikke t, reagerer men de s ul.fu re rt e forbindelser som er frigjort under steriliseringen og forårsaker dannelse av tinn (II) su.! f id , hvilket vises ved "ma rn-> r iner i ng" av tinnet eller dannelse av striper på tinnet. Herved antar den indre overflate av boksen et brun.! i gol å 11 utseende. De r. si; ion kan hydro-gensulfidet forårsake danneino av ferrosul fid i pu.l verforra, som danner sorte flekker på metallet og likeledes gir flekker på pro-, duktet.
Por å beskytte den indre overflate av hermetikkboksene og deres innhold mot disse "sulfureringsfenomener" er det allerede <! >kjent å påfbre et lakkbelegg på tinnblikket.
Forskjellige typer lakk har allerede vært foreslått for dette formål.
For det f5rste har det vært foreslått ikke-pigmenterte lakker med tilbøyelighet til å hindre gjennomtrengning av hydrogensulfid og/eller mercaptaner. Disse lakker er beheftet med den ulempe at de ikke opptar de sulfurerte forbindelser som frigjores under den; termiske spaltning av proteinene. De danner bare ganske enkelt en Vegg.
Det har også vært foreslått å anvende lakker som inneholder a.luminiumpulver, i den hensikt å danne et ugjennomsiktig belegg.. Sulfureringen av hermetikkboksen som er overtrukket med en film av denne art, blir herved ganske enkelt skjult av aluminiumet. De sulfurerte forbindelser opptas ikke, men lakken skjuler bare til-stedeværelsen av tinn(II)sulfid under lakken.
Lakker, betegnet som "anti-svovel"-lakker og fremstilt på basis av en oljeharpikslakk med en tilsetning av sinkoxyd har også vært foreslått. Disse forbindelser reagerer med de sulfurerte forbindelser og "fikserer" de sistnevnte i form av sinksulfid. Da. sistnevnte forbindelse er hvitfarvet som oxydet, blir det ingen endring i lakkens utseende.
Ennskjont lakker av denne siste type gir tilfredsstillende resultater med hensyn til fiksering av sulfurerte spaltningspro- • dukter under steriliseringen, lider de av forskjellige mangler som er velkjente i hermetikkindustrien. Spesielt gir de lett produkter med mild smak og aroma en fettlignende smak. Dessuten oppviser de liten resistens mot den varme som overfores under gjenloddingen av hermetikkboksene ved hjelp av lodd.emeta.ller med \ lav tinngehalt, og det er fare for tap av hefteevnen til den fortinnede vegg når de er i kontakt med fettholdige produkter (f.ek^. kjott og posteier).
I
For å overvinne disse ulemper har det allerede vært forsokt j fremstilt anti-svovel-lakker basert på syntetiske bindemidler, i såsom epoxy-fenoliske harpikser, epoxy-ureaformaldehyd-harpikser, polybutadienharpikser og andre harpikser. Erfaringen har imidler-tid vist at reaktiviteten av sinkoxyd med sulfurerte forbindelser, som er utmerket i oljeharpikslakker, blir dårlig eller bortfaller helt i syntetiske bindemidler av nevnte ort.
Det er et hovedmål med den foreliggende oppfinnelse å bibringe syntetiske lakker av denne art anti-svovel-egenskaper, dvs. evne til å oppta de sulfurerte forbindelser som utvikles under steriliseringen av visse næringsmidler.
Ved hjelp av oppfinnelsen tilveiebringes det således en lakk for overtrekning av innsiden av bokser av fortinnet blikk, spesielt hermetikkbokser, hvilken lakk inneholder et syntetisk bindemiddel og et fyllstoff og er karakteristisk ved at fyllstoffet er sinkcarbonat.
Lakken ifblge oppfinnelsen kan inneholde et syntetisk bindemiddel av epoxy-fenolisk type eller et syntetisk bindemiddel av annen type. Sinkcarbonatet som innenoJdes i lakken ifblge oppfinnelsen, reagerer lett med hydrogensulfid og sulfurerte spaltningsprodukter av typen R - SH, hvor R er et proteinradikal.
Patentinnehaveren har funnet at mens sinkoxyd som er innar-beidet i syntetiske bindemidler, fullstendig eller i stor utstrek-ning mister sin evne til å reagere med sulfurerte forbindelser, vil sinkcarbonat som er innlemmet i de nevnte lakker, meget effek-tivt oppta de sulfurerte forbindelser i form av sulfider.
Sinkcarbonat oppviser en rekke nbdvendige egenskaper ved siden av den egenskap at det lett reagerer med S- og HS-anioner, nemlig ved at det:
- ikke er giftig,
- er meget lite opplbselig i vann,
- tåler betingelsene ved varmherdningen av lakken,
- har et lett anion bundet til metallet, hvorved det unngåes overdrevent stor bkning av vektforholdet pigment:bindemiddel i lakkfilmen,
- har samme fa.rve som sulfidet og
- er akseptabelt fra et bkonomisk synspunkt.
Sinkcarbonatfyllstoffet dispergeres i den som bindemiddel virkende syntetiske lakk etter konvensjonelle metoder i maling- ;
og lakkindustrien.
Den mengde sinkcarbonat som tilsettes lakken, kan varieres etter bnske, avhengig av mengden av sulfurerte forbindelser som det bnskes å fiksere.
De nedenstående eksempler vil ytterligere illustrere oppfinnelsen.
Eksempel 1
5 g finmalt ZnCO^ dispergeres i 100 g av en epoxy-fenolisk lakk med 30 "/ > tbrrekstrakt og hvis epoxy-fenol-forhold er 70:30. Dispergeringen utfores ved hjelp av en kuiemolle eller ved hjelp
av en liten mol le med tre sy]indre.
Etter justering av viskositeten ved hjelp av et egnet for-tynningsmiddel ble den således pigmenterte lakk påfbrt fortinnet blikk ved hjelp av ruller og deretter varmherdet under de samme betingelser som man ville ha anvendt dersom den ikke var pigmen-tert. Denne operasjon hadde som formål å avdrive opplosningsmid-lene og å frembringe polymerisering av den epoxy-fenoliske haxpiks.
Ut fra således lakkede, fortinnede blikk ble der så fremstilt bokser etter konvensjonelle metoder.
"Por å prove den pigmenterte lakks mostandsevne mot sulfurerte forbindelser ble blikkboksene fyl It med erter i saltlake og deretter lukket og sterilisert i. 90 minutter ved 120°0. Etter kjbling og lagring i forskjellige tidsrom ble boksene åpnet og innholdet tomt ut. Det viste seg at ingen sulfurering av det underliggende tinn hadde funnet sted. Heller ikke var det blitt dannet noe ferrosulfid i boksens åpne rom.
Et annet forsok ble utfort parallelt med det ovennevnte, under anvendelse av den samme epoxy-fenoliske harpiks men uten pigment. Det viste neg at, det hadde funnet sted sulfurering av de + underliggende tinn, og at det også var dannet ferrosulfid i boksens frie rom.
Et tredje forsok nom også ble ut fort parallelt under anvendelse av 'i'.-!- 3-!;n:;ie epoxy- f enol i. ske harpik;;, men som denne gang var pigment ert :ae J det i maling- og 1 akki o.- lw.- ; trien vanlig brukte sinkoxyd i ":j"ioilot 5 g pigment tii 100 g flytende harpiks,
viste de 3.-jiune .'^'Vktor 3 om i oven nevnte annet forsok da. boksene ble å r;ne t.
Eksempel 2
10 g finmalt ZnCO^ ble dispergert i 100 g lakk på basis av polybutadien med 52 % torrekstrakt. Dispersjonen ble fremstilt J ved hjelp av konvensjonelle innretninger på samme måte som i eksempel 1. Etter justering av viskositeten ved hjelp av et egnet for-tynningsmiddel ble den pigmenterte lakk påfbrt fortinnede blikk-i •plater på samme måte som i eksempel 1. Forsbket ble utfort som tidligere beskrevet. Det viste seg at ingen sulfurering av det underliggende tinn hadde funnet sted og heller ingen dannelse av ferrosulfid.
Eksempel 3
6 g finmalt ZnCO^ ble dispergert i 100 g av en lokk på basis a.v epoxy-urea-formaldehyd med 37 c/ > tbrrekstrakt. Dispergeringen
ble utfort som ovenfor beskrevet, og forsbket ble utfort på ana-log måte. Det viste seg at ingen sulfurering av det underliggende tinn hadde funnet sted og heller ingen dannelse av ferrosulfid.
