Description
Oppfinnelsen vedrører pastaer til behandling f.eks. rensning av metalliske eller ikke-metalliske overflater og bestående av et pastagrunnlag og stoffer med slipe-, polerings-*-, meta11rense-, pusse- eller korrosjonsbeskyttelsesvirkning samt en fremgangsmåte til fremstilling av disse pastaer. The invention relates to pastes for treatment e.g. cleaning of metallic or non-metallic surfaces and consisting of a paste base and substances with abrasive, polishing*, metal cleaning, polishing or corrosion protection action as well as a method for producing these pastes.
Prinsippielt kan man som bekjent overføre vandige eller ikke vandige, flytende systemer i pastaer ved at man til dem setter en så stor mengde av uorganiske eller organiske fyllstoffer under omrøring eller knaing inntil den ønskede konsistens er oppnådd. Den hver gang nødvendige mengde fyllstoff avhenger helt av fyllstoffets type. Således krever man eksempelvis.for å fortykke en vandig syre meget mindre fyllstoff, når man som sådant anvender findispers kiselsyre i stedet for grove re kiselgur. In principle, as is well known, aqueous or non-aqueous, liquid systems can be transferred into pastes by adding such a large amount of inorganic or organic fillers while stirring or kneading until the desired consistency is achieved. The amount of filler required each time depends entirely on the type of filler. Thus, for example, to thicken an aqueous acid, much less filler is required, when finely dispersed silicic acid is used as such instead of coarse diatomaceous earth.
Likeledes meget store fyllstoffmengder kreves når Likewise, very large amounts of filler are required when
man f.eks. knar langkjedede fettaminer som selv har en korro-sjonsbeskyttelse for fremstilling av pastøse smøremidler, som har antikorrosive egenskaper for metaller med syrer, f.eks. fosforsyre, fortrinnsvis kromsyre hvis salter likeledes er meget gode korrosjonsbeskyttelsesmidler for metall, således at mengden av det i det eventuelle amin dannede faststoff er tilstrekkelig som fyllstoff for fortykning (britisk patent nr. 1.010.7131. Disse med store mengder av faste stoffer deigdannede oljeaktige stoffer inneholder ikke i noe til- one e.g. knar long-chain fatty amines which themselves have corrosion protection for the production of pasty lubricants, which have anti-corrosive properties for metals with acids, e.g. phosphoric acid, preferably chromic acid, the salts of which are also very good corrosion protection agents for metal, so that the amount of solids formed in any amine is sufficient as a filler for thickening (British patent no. 1.010.7131. These pasty oily substances with large amounts of solids does not contain any additional
felle fri syrer, da det dreier seg om smøremidler. trap free acids, as they are lubricants.
Det har likeledes i lengere tid vært kjent at man It has also been known for a long time that one
kan overføre flytende systemer i pastaer ved dannelse av emulsjoner. Herved kreves mindre organisk fyllstoff enn ved de ovenfor omtalte faste dispersjoner. Således kan man eksempelvis emulgere fettsyrer ved hjelp av en emulgator, fortrinnsvis av et ammoniumsalt av denne syre i vann, således at det oppstår en pasta. I stedet for fettsyrer lar det seg også anvende som ventet andre forbindelser med lange hydrokarbonkjeder, idet man deretter ikke kan fremstille emulgatoren fra selve pastagrunnlaget, men å tilsette den f.eks. med parafinolje eller ved fettalkoholer. Denne type pastadannelse har i lengere tid vært anvendt i mange anvend- can transfer liquid systems into pastes by forming emulsions. This requires less organic filler than with the above-mentioned solid dispersions. Thus, for example, fatty acids can be emulsified using an emulsifier, preferably an ammonium salt of this acid in water, so that a paste is formed. Instead of fatty acids, it is also possible to use, as expected, other compounds with long hydrocarbon chains, since the emulsifier cannot then be produced from the paste base itself, but adding it e.g. with paraffin oil or with fatty alcohols. This type of paste formation has for a long time been used in many applications
elsesområder, således f.eks. i næringsmiddelkjemien, kosmetikk osv. J other areas, thus e.g. in food chemistry, cosmetics, etc. J
Man kan på denne måte også overføre vandige syrer Aqueous acids can also be transferred in this way
i pastøs form. Således er det ifølge tysk patent nr; 1.Q82.475 kjent å fremstille avrustningspastaer som ved siden av fosforsyre inneholder et fortykningsmiddel, f.eks. en forsåpbar olje eller en i en såpe overførbar fettsyre samt som overflateaktivt middel en emulgator, f.eks. et tertiært amin, som har en fett-alkylgruppe og to polyoksyetylenkjeder ved nitrogenatornet eller fettsyreamider, som ved nitrogenatomet har to polyoksyetylenkjeder. in pasty form. Thus, according to German patent no; 1.Q82.475 known to produce disarmament pastes which, in addition to phosphoric acid, contain a thickening agent, e.g. a saponifiable oil or a soap-transferable fatty acid and, as a surface-active agent, an emulsifier, e.g. a tertiary amine, which has a fatty alkyl group and two polyoxyethylene chains at the nitrogen atom or fatty acid amides, which have two polyoxyethylene chains at the nitrogen atom.
Hertil ble det blandet med hverandre, f.eks. 75%-ig fosforsyre og vann på den ene side samt amin og stearinsyre på den annen side i adskilte kar, begge blandinger oppvarmet i 60°C og deretter ble den annen blanding helt inn i første. Derved får man en tyntflytende, kremlignende masse, som ved henstand natten over tykner-til en glatt pasta. In addition, it was mixed with each other, e.g. 75% phosphoric acid and water on one side and amine and stearic acid on the other side in separate vessels, both mixtures heated to 60°C and then the second mixture was poured into the first. This results in a thin, cream-like mass, which, when left overnight, thickens into a smooth paste.
Avrustningspastaer som fremstilles på grunnlag av emulsjoner har imidlertid den ulempe at som pastagrunnlag er det tilstede kjemiske forbindelser, som hverken er delaktige i avrustningsprosessen eller sikrer noen langvarig rustbe-skyttelse. Man må derfor i slike tilfeller tilsette et korrosjonsbeskyttelsesmiddel, således at en formålstjenelig av-rustningspasta skulle bestå av komponentene pastagrunnlag, vandig syre og korrosjonsbeskyttelsesmiddel. Dessuten er det en egenskap ved emulsjonen at strukturen ødelegges ved inn-tørkning. Derved foregår skjolldannelser som fører til en jevn innvirkning av den til avrustning tjenende syre. Derusting pastes that are produced on the basis of emulsions, however, have the disadvantage that chemical compounds are present as the paste base, which neither take part in the derusting process nor ensure any long-term rust protection. A corrosion protection agent must therefore be added in such cases, so that a suitable disarmament paste should consist of the components paste base, aqueous acid and corrosion protection agent. Moreover, it is a property of the emulsion that the structure is destroyed by drying. Thereby, crust formation takes place which leads to a uniform impact of the disarming acid.
Oppfinnelsen vedrører nå en pasta til behandling, f.eks. rensning av metalliske eller ikke-metalliske overflater, bestående av et pastagrunnlag og stoffer med slipe-, poler-ings-, metallrense-, pusse- eller korrosjonsbeskyttelsesvirkning som aminer, syrer, voks, silikoner, slipemidler, The invention now relates to a paste for treatment, e.g. cleaning of metallic or non-metallic surfaces, consisting of a paste base and substances with grinding, polishing, metal cleaning, polishing or corrosion protection effects such as amines, acids, waxes, silicones, abrasives,
idet pastaen er karakterisert ved at det inneholdte pastagrunnlag er fremstilt ved at man i en på forhånd fremstilt vandig dispersjon av et langkjedet amin, spesielt med 12-18 C-atomer, ved forhøyet temperatur - fortrinnsvis 80°C - inn-fører likeledes til fortrinnsvis 80°C forhåndsoppvarmet fos- in that the paste is characterized in that the contained paste base is prepared by introducing into a previously prepared aqueous dispersion of a long-chain amine, especially with 12-18 C atoms, at an elevated temperature - preferably 80°C - preferably 80°C preheated phos-
forsyre av en konsentrasjon fra 5-90 vekt-%, fortrinnsvis fra 30-60 vekt-%.under kraftig omrøring til oppnåelse av nøytra-lisasjonspunktet, og deretter rører reaksjonsblandingen kald. acidify at a concentration of from 5-90% by weight, preferably from 30-60% by weight, with vigorous stirring until the neutralization point is reached, and then stir the reaction mixture cold.
Disse pastaer fåes ved at man med en fremstilt eventuelt under anvendelse av emulgatorfremstilt dispersjon av et langkjedet amin med en forhøyet temperatur, likeledes innfører foroppvarmet fosforsyre under kraftig omrøring til oppnåelse av nøytralitetspunktet og deretter i det således dannede pastagrunnlag ved reaksjonstemperaturen eller ved lavere temperatur under kaldrøringen innfører de øvrige pastakompo-nenter. These pastes are obtained by using a dispersion of a long-chain amine prepared using an emulsifier at an elevated temperature, likewise introducing preheated phosphoric acid under vigorous stirring to reach the neutrality point and then into the thus formed paste base at the reaction temperature or at a lower temperature during the cold stirring introduces the other pasta components.
Pastagrunnlaget kan i tillegg inneholde kjente emulgatorer, f.eks. slike på basis av organiske fosforsyreestere. Dessuten kan det likeledes for bedre dispergering inneholde med vann ikke blandbare organiske oppløsningsmidler, som eksempelvis parafinhydrokarboner, spesielt petroleum samt klorerte hydrokarboner. Derved kan emulgatorene anvendes i mengder fra 5-10 vekt-%, referert til aminene og hvis det anvendes et organisk oppløsningsmiddel i de vanlige mengder fra 5-10 vekt-%, referert til dette oppløsningsmiddel. The pasta base can also contain known emulsifiers, e.g. such on the basis of organic phosphoric acid esters. Moreover, for better dispersion, it may also contain water-immiscible organic solvents, such as, for example, paraffin hydrocarbons, especially petroleum and chlorinated hydrocarbons. Thereby, the emulsifiers can be used in amounts from 5-10% by weight, referred to the amines and if an organic solvent is used in the usual amounts from 5-10% by weight, referred to this solvent.
Som langkjedede aminer egner seg spesielt slike med en hydrokarbonkjede fra 12-18 karbonatomer, nemlig de tilsvarende alkylaminer, alkylendiaminer eller andre aminer med en eller flere aminfunksjoner av primære, sekundære eller tertiære typer til en langkjedet, ikke substituert eller substituert hydrokarbonrest, som eksempelvis stearylamin, oleylamin og fettaminblandinger, som kokosfettamin eller talgfettamin. As long-chain amines, those with a hydrocarbon chain of 12-18 carbon atoms are particularly suitable, namely the corresponding alkylamines, alkylenediamines or other amines with one or more amine functions of primary, secondary or tertiary types to a long-chain, unsubstituted or substituted hydrocarbon residue, such as for example stearylamine , oleylamine and fat amine mixtures, such as coconut fat amine or tallow fat amine.
Etter oppnåelse av nøytralisasjonspunktet settes det til reaksjonsblandingen alt etter anvendelsesformålet av pastaen ytterligere komponenter ved reaksjonstemperaturen eller ved lavere temperaturer. After reaching the neutralization point, additional components are added to the reaction mixture at the reaction temperature or at lower temperatures, depending on the intended use of the paste.
Slike komponenter kan eksempelvis være: igjen fosforsyre og/eller langkjedede aminer, kortkjedede aminer og/eller uorganiske resp. organiske syrer, som f.eks. oksal-syre, vinsyre, svovelsyre, saltsyre, flussyre, salpetersyre og/eller slipemidler, f.eks. kvartsmel eller poleringsleirjord og/eller hjelpestoff, som tiourinstoff, ammoniumklorid samt andre som spesielle metallrense- resp. pusse- eller korrosjonsbeskyttelsesmidler kjente stoffer, som f.eks. voks, voks-syrer, silikonolje osv. Such components can be, for example: again phosphoric acid and/or long-chain amines, short-chain amines and/or inorganic resp. organic acids, such as oxalic acid, tartaric acid, sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid and/or abrasives, e.g. quartz flour or polishing clay and/or auxiliary substances, such as thiourea, ammonium chloride and others such as special metal cleaners or polishing or corrosion protection agents known substances, such as e.g. wax, wax acids, silicone oil, etc.
De ifølge oppfinnelsen fremstilte pastaer kan finne anvendelse, eksempelvis til behandling av metalloverflater, spesielt som metallrense- eller rustfjerningsmiddel eller f.eks. også til rensning av betongoverflater og når produktene inneholder flussyre til etsing av glass. The pastes produced according to the invention can be used, for example for the treatment of metal surfaces, especially as a metal cleaning or rust removal agent or e.g. also for cleaning concrete surfaces and when the products contain hydrofluoric acid for etching glass.
De ifølge oppfinnelsen fremstilte produkter har i forhold til de kjente pastaer en rekke fordeler. De dispo-nerer over en høy konsentrasjon av virksomt stoff, da de foruten de for overflatebehandlingen nødvendige komponenter ikke inneholder artsfremmet pastagrunnlag. De lar seg lett, eventuelt ved vasking med vann, igjen fjerne fra flater hvorpå de ble påført, idet de f.eks. etterlater en hydrofob, beskyttelsesfilm med uvanlig langvarig virkning på blanke metalloverflater. De kan alt etter anvendelsesformål inn-stilles surt, nøytralt eller basisk. The products produced according to the invention have a number of advantages compared to the known pastes. They have a high concentration of active substance, as apart from the components required for the surface treatment, they do not contain a species-promoted paste base. They can be easily, if necessary by washing with water, again removed from surfaces on which they were applied, as they e.g. leaves a hydrophobic, protective film with an unusually long-lasting effect on shiny metal surfaces. Depending on the intended use, they can be set to acidic, neutral or basic.
Oppfinnelsen skal forklares nærmere ved hjelp av noen eksempler. The invention will be explained in more detail with the help of some examples.
Eksempel_l Example_l
4 g stearylamin oppvarmes med 48 g vann i vannbad ved 80°C og glattrøres med en huftigløpende rører. Derpå tilsettes langsomt under omrøring så mange vektdeler til ca. 80°C foroppvarmet, 85 vekt-%-ig fosforsyre inntil nøy-tralisasjonspunktet er nådd. 4 g of stearylamine are heated with 48 g of water in a water bath at 80°C and stirred smoothly with a high-speed stirrer. Then add slowly while stirring as many parts by weight as approx. 80°C preheated, 85% by weight phosphoric acid until the neutralization point is reached.
Til det således dannede pastagrunnlag settes ved oppnåelse av nøytralisasjonspunktet eller senere inntil 30 vekt-% slipemiddel, referert til pastagrunnlaget. Den derved fremstilte pasta anvendes som metallpussmiddel med en rustoppløsende virkning og utmerker seg i forhold til for dette formål allerede kjente pastaer ved at den mekaniske renseeffekt kompletteres med den kjemiske rustfjerning. When the neutralization point is reached or later, up to 30% by weight of abrasive is added to the paste base thus formed, referred to the paste base. The resulting paste is used as a metal polishing agent with a rust-dissolving effect and differs from pastes already known for this purpose in that the mechanical cleaning effect is complemented by chemical rust removal.
Eksempel_2 Example_2
Det gåes i første rekke fram som i eksempel 1 og etter oppnåelse av nøytralisasjonspunktet settes til pastagrunnlaget en svakt sur oppløsning av 8 g tiourinstoff i 50 g vann. Dessuten kan man tilsette poleringsmidler, voks og oppløsningsmidler og får således et virksomt sølvpussemiddel med et korrosjonsbeskyttelsesmiddel som pastagrunnlag. I stedet for tiourinstoff kan man anvende ammoniumklorid og fremstiller da et kobberpussmiddel med et korrosjonsbeskyttelsesmiddel som pastagrunnlag. Proceed primarily as in example 1 and, after reaching the neutralization point, a weakly acidic solution of 8 g of thiourea in 50 g of water is added to the paste base. In addition, you can add polishing agents, waxes and solvents and thus get an effective silver polishing agent with a corrosion protection agent as a paste base. Instead of thiourea, you can use ammonium chloride and then prepare a copper polishing agent with a corrosion protection agent as a paste base.
Eksempel_3 Example_3
Til fremstilling av et nøytralt metallpussemiddel omsetter man i første rekke 3 g stearylamin, 4 g emulgator på basis av organisk fosforsyreester, 50 g vann samt 20 g petroleum med 1,3 g 85 vekt-%-ig fosforsyre analogt eksempel 1 og tilsetter deretter til reaksjonsproduktet 4 g av en vokssyre, 20 g poleringsleirjord, 20 g av et slipemiddel samt 5 g silikonolje. To produce a neutral metal polishing agent, 3 g of stearylamine, 4 g of emulsifier based on organic phosphoric acid ester, 50 g of water and 20 g of petroleum are first reacted with 1.3 g of 85% by weight phosphoric acid analogous to example 1 and then added to the reaction product 4 g of a waxy acid, 20 g of polishing clay, 20 g of an abrasive and 5 g of silicone oil.
