Abstract

Lubricant based on resin, preferably Teflon, dispersed in silicone oil, 2-50 wt% of resin being dispersed in the case of Teflon. Teflon is preferably dispersed in the silicone oil by means of a suitable detergent. The novel lubricant is particularly suitable for lubricating conveyors in ovens for bakery products.

Description

Smeermiddelen op basis van een in een drager gedispergeerde vaste hars en toepassing hiervan.Lubricants based on a solid resin dispersed in a carrier and use thereof.

De uitvinding heeft betrekking op een smeermiddel, in hoofdzaak bestaande uit een drager en een in de drager gedispergeerde vaste hars.The invention relates to a lubricant consisting essentially of a carrier and a solid resin dispersed in the carrier.

Uit US-A-3194762, zie ondermeer kolom 1 regel 59 tm kolom 2 regel 34, is een dergelijk smeermiddel bekend voor onder meer onder bijzonder hoge druk werkende overbrengingen.From US-A-3194762, see, inter alia, column 1 line 59 to column 2 line 34, such a lubricant is known for, inter alia, transmissions operating under particularly high pressure.

Als in de drager onoplosbare harsen worden onder meer vermeld nylon en teflon.Examples of resins insoluble in the carrier are nylon and teflon.

Genoemd smeermiddel voldoet echter niet als smeermiddel voor transporteurs in bakkersovens, doordat als basisolie of drager een minerale olie, of dierlijk of plantaardige olie wordt toegepast, zie kolom 3 regels 6 tm 20 en kolom 4 regels 31 tm 33.However, said lubricant is not sufficient as a lubricant for bakers in bakery ovens, because a base oil or carrier is used with a mineral oil, or animal or vegetable oil, see column 3 lines 6 to 20 and column 4 lines 31 to 33.

De uitvinding beoogt dat nadeel nu te vermijden door als dragerolie siliconenolie toe te passen.The object of the invention is now to avoid this drawback by using silicone oil as the carrier oil.

Uit US-A-3933366 is weliswaar op zichzelf bekend het toepassen van een silaan bij het statiseren van een fluorkool-stofhars dispersie in minerale smeerolie.It is known per se from US-A-3933366 that the use of a silane in the stabilization of a fluorocarbon resin dispersion in mineral lubricating oil is known per se.

Het toegepaste silaan is echter geen polysiloxaan verbinding, die zoals bij de uitvinding als drager bij het smeermiddel wordt toegepast.However, the silane used is not a silicone compound which, as in the present invention, is used as a carrier for the lubricant.

Als siliconenolie wordt bij voorkeur toegepast Silicone Oil SF 96 commercieel verkrijgbaar onder meer van de firma R.S.Stokvis, Rotterdam.Silicone oil SF 96 is preferably used as silicone oil, commercially available, inter alia from the company R.S.Stokvis, Rotterdam.

Een andere zeer goed bruikbare siliconenolie is een siliconenolie verkrijgbaar van Aldrich Chemie nv/sa, Brussel, onder no. 17,563-3 "Silicone oil, high temperature".Another very useful silicone oil is a silicone oil available from Aldrich Chemie nv / sa, Brussels, under no. 17.563-3 "Silicone oil, high temperature".

Als voorkeurshars wordt het eerder reeds genoemde teflon gedispergeerd in de siliconenolie toegepast.As the preferred resin, the aforementioned teflon dispersed in the silicone oil is used.

Onder teflon zijn behalve polytetrafluorethyleen (PTFE) ook andere, verwante fluor bevattende polymeren te verstaan, zoals Teflon (PFA) en teflon (FEP).In addition to polytetrafluoroethylene (PTFE), Teflon also includes other related fluorine-containing polymers, such as Teflon (PFA) and Teflon (FEP).

Het traject waarin teflon kan worden bijgemengd met de siliconenolie ligt tussen 2 en 50 gew.%.The range in which teflon can be mixed with the silicone oil is between 2 and 50% by weight.

Hoewel soms geen detergent noodzakelijk is, verdient het aanbeveling om een niet ionisch detergent toe te passen om de teflon in de siliconenolie te dispergeren.Although sometimes no detergent is necessary, it is recommended to use a non-ionic detergent to disperse the Teflon in the silicone oil.

Geschikte niet ionische detergenten zijn: dipropyleen glycolmonomethylether en nonylfenolpoly glycol-ether.Suitable non-ionic detergents are dipropylene glycol monomethyl ether and nonylphenol poly glycol ether.

Een goede deeltjes afmeting van het te dispergeren teflon is 3 - 5 micron (n m).A good particle size of the teflon to be dispersed is 3-5 microns (n m).

Het smeermiddel als eerder vermeld kan worden toegepast in een oven voor de behandeling van producten bij hoge temperatuur voor het smeren van de transporteur(s) en andere bewegende delen.The lubricant as previously mentioned can be used in an oven for the treatment of high temperature products for lubricating the conveyor (s) and other moving parts.

Een voorbeeld van een dergelijke oven is een oven voor bijvoorbeeld bakkerswaren.An example of such an oven is an oven for bakery products, for example.

De uitvinding wordt hieronder zonder enige bedoeling tot beperking toegelicht met twee voorbeelden.The invention is illustrated below without any intention of limitation with two examples.

Voorbeeld 1Example 1

In een laboratoriummenger met hoge schuifspanningswerking werd eerst 100 gram van de eerdervermelde siliconenolie SF 96 gebracht, de menger werd aangezet, waarna achtereenvolgens 5 gram dipropyleen glycolmonomethylether en 10 gram fijn teflonpoeder werden toegevoegd.100 grams of the aforementioned silicone oil SF 96 was first introduced into a high shear laboratory laboratory mixer, the mixer was turned on and 5 grams of dipropylene glycol monomethyl ether and 10 grams of fine Teflon powder were successively added.

Het teflonpoeder vertoonde een gemiddelde deeltjesafme-ting van 2-5 micron (n m).The Teflon powder showed an average particle size of 2-5 microns (n m).

Na 10 minuten mengen werd een stabiele homogene dispersie verkregen.After 10 minutes of mixing, a stable homogeneous dispersion was obtained.

De verkregen dispersie voldeed uitstekend als smeermiddel voor de transporteurs van een oven voor de productie van zogeheten stroopwafels; dit in tegenstelling tot een smeermiddel dat uit siliconenolie SF 96 zonder bijvoeging bestaat. Zuivere siliconenolie SF 96 voldoet in het begin goed, maar na één dag moeten de transporteurkettingen opnieuw gesmeerd, omdat de siliconenolie verdampt is.The dispersion obtained was excellent as a lubricant for the conveyors of an oven for the production of so-called stroopwafels; this in contrast to a lubricant consisting of SF 96 silicone oil without additives. SF 96 pure silicone oil is satisfactory at first, but after one day the conveyor chains must be re-lubricated, because the silicone oil has evaporated.

Het verdampen van de siliconenolie vindt plaats bij een baktemperatuur van 250°C.The silicone oil evaporates at a baking temperature of 250 ° C.

Met de nieuwe smeermiddeldispergie volgens de uitvinding werd de stellige indruk verkregen dat de oventransporteurs beter functioneerden.With the new lubricant dispersion according to the invention, the clear impression was obtained that the oven conveyors functioned better.

Voorbeeld 2Example 2

De werkwijze van Voorbeeld 1 werd herhaald, waarbij als siliconenolie de eerder vermelde siliconenolie van Aldrich no. 17,563-3 high temperature en als detergent nonylfenylpolygly-colether werden toegepast.The procedure of Example 1 was repeated, using as silicone oil the aforementioned silicone oil of Aldrich No. 17.563-3 high temperature and as detergent nonylphenylpolyglycolether.

De hoeveelheden waren verder gelijk aan die van Voorbeeld 1.The amounts were otherwise similar to those of Example 1.

De verkregen dispersie voldeed eveneens zeer goed als smeermiddel voor transporteurs van een oven voor het bakken van stroopwafels.The dispersion obtained was also very satisfactory as a lubricant for conveyors of an oven for baking stroopwafels.
