Description

Thixotrop emulsjon. Thixotropic emulsion.

Nærværende oppfinnelse vedrører thixotrope emulsjonsblandinger og emulsjons-malingsblandinger fremstilt fra disse. The present invention relates to thixotropic emulsion mixtures and emulsion-paint mixtures prepared from these.

Thixotrope malingsbærere, fremstilt f. eks. fra oljemodifiserte alkydharpikser inneholdende en del bundet polyamidhar-piks og oppløst i alifatiske oppiløsningsmid-ler er blitt markedsført og anvendt i ma-lingsindustrien i noen tid. Fordelene ved thixotrope malinger i motsetning til malinger som har normale flyteegenskaper er, at de har mindre tilbøyelighet til å dryppe fra kosten og at et tykkere over-trekk kan påføres uten fare for ujevnheter. Pigmentsuspensjonsegenskapene er også bedre. Ekstrem thixotropi representeres av en gelstruktur som etter definisjonen fort vil brytes ned til en fritt flytende væske under kraftig omrøring eller ved sterk på-kjenning som følge av anvendelse av kost eller rulle. En thixotrop gel tillater bruke-ren å anvende større malingsmengder på kosten enn det er mulig med en ikke thixotrop maling, med følgen tidsbesparelse ved påføringen. Dessuten vil tilfeldig hvelving av kanne eller boks ikke resultere i det nesten totale tap av innholdet som ellers normalt er tilfellet. En god thixotrop maling skal reduseres til normal viskositet under anvendelsen og tillate kostmerker å flyte ut når skjærkraften oppheves, men skal også oppvise tilstrekkelig kort gjen-opprettelsestid for å forhindre at merker eller annet opptrer når en tykk film på-føres. Thixotropic paint carriers, produced e.g. from oil-modified alkyd resins containing a portion of bound polyamide resin and dissolved in aliphatic solvents have been marketed and used in the paint industry for some time. The advantages of thixotropic paints in contrast to paints that have normal flow properties are that they have less tendency to drip from the brush and that a thicker overcoat can be applied without the risk of unevenness. The pigment suspension properties are also better. Extreme thixotropy is represented by a gel structure which, according to the definition, will quickly break down into a free-flowing liquid under vigorous stirring or under strong stress as a result of the use of a broom or roller. A thixotropic gel allows the user to apply larger amounts of paint on the brush than is possible with a non-thixotropic paint, with the consequent time saving during application. Also, accidental tipping of the jug or can will not result in the almost total loss of contents which is otherwise normally the case. A good thixotropic paint should reduce to normal viscosity during application and allow paint marks to flow out when the shear force is removed, but should also exhibit a sufficiently short recovery time to prevent marks or otherwise appearing when a thick film is applied.

Inntil nå er emulsjoner eller emulsjonsmalinger med egnede thixotrope egenskaper ikke blitt fremstilt i industriell målestokk. Det er imidlertid kjent at inn-førselen av opp til 6 vektspst. av et vann-oppløselig alkalimetallsilikat med formelen (M20)nSiOi;, i hvilken M betyr et alkali-metall og n ligger innenfor området 3,0 til 4,0, vil fremkalle thixotropi i polyvinyl-acetatemulsjonsmalinger. Denne spesielle metode har ulempen av å innføre perma-nent vannoppløselige metallsalter i malingen med medfølgende mulighet for salt-utslag og redusert vannmotstandsevne. Malinger fremstilt på dette grunnlag har også tendens til å lide under effekten kjent som synerese, d. v. s. utskillelse av væske på overflaten på grunn av gelens krymp-ing. Until now, emulsions or emulsion paints with suitable thixotropic properties have not been produced on an industrial scale. It is known, however, that the import of up to 6 wt. of a water-soluble alkali metal silicate of the formula (M2O)nSiOi;, in which M is an alkali metal and n is within the range of 3.0 to 4.0, will induce thixotropy in polyvinyl acetate emulsion paints. This particular method has the disadvantage of introducing permanently water-soluble metal salts into the paint, with the accompanying possibility of salt rash and reduced water resistance. Paints produced on this basis also tend to suffer from the effect known as syneresis, i.e. the shedding of liquid on the surface due to the shrinkage of the gel.

En annen metode som gjør bruk av kombinasjoner av polyvalente kationer slik som Ca-H- med polyanioner av komplekse kopolymerer, som formaldehyd-nafthalen-sulfonsyrekondensasjonsprodukter er kjent for å gi thixotrope malinger som også lider av visse ulemper. Malinger fremstilt etter denne metode er temperaturfølsomme og gelens gjenopprettelsestider er betraktet som ekstremt lange. Another method which makes use of combinations of polyvalent cations such as Ca-H- with polyanions of complex copolymers, such as formaldehyde-naphthalene-sulfonic acid condensation products is known to give thixotropic paints which also suffer from certain disadvantages. Paints produced using this method are temperature sensitive and the recovery times of the gel are considered extremely long.

Det er nå funnet at thixotrope emulsjonsmalinger kan fremstilles ved tilset-ning av vannoppløselige titanchelater. Anvendelsen av disse materialer til forskjell fra alkalimetallsilikater er ikke begrenset til behandlingen av emulsjonsmalinger basert på vinylacetatpolymere eller kopolymere. Det er funnet at thixotrope geler kan oppnåes når titanchelatet tilsettes til mange varianter av emulsjoner og emulsjonsmalinger og slike malinger viser i det minste to betydelige fordeler overfor tidligere thixotrope emulsjonsmalinger. For det første er opptreden av synerese meget mindre markert og for det annet viser filmene forbedret motsandsevne overfor vann og slitasje i sammenlikning med filmer fra malinger som ikke inneholder titantilsetningen. It has now been found that thixotropic emulsion paints can be produced by adding water-soluble titanium chelates. The use of these materials, unlike alkali metal silicates, is not limited to the treatment of emulsion paints based on vinyl acetate polymers or copolymers. It has been found that thixotropic gels can be obtained when the titanium chelate is added to many varieties of emulsions and emulsion paints and such paints show at least two significant advantages over earlier thixotropic emulsion paints. Firstly, the occurrence of syneresis is much less marked and secondly, the films show improved resistance to water and abrasion compared to films from paints which do not contain the titanium additive.

Ifølge nærværende oppfinnelse er det fremskaffet en thixotrop emulsjon bestå-ende av en vandig emulsjon av en filmdannende polymer eller kopolymer, som dessuten inneholder et naturlig eller syntetisk vannoppløselig hydroxylholdig organisk, kolloid, som, derivater av stivelse eller cellulose eller polyvinylalkohol, sammen med 0,25 til 5 vektspst. av titanchelatet basert på emulsjonens vekt. Andre beskyt-tende kolloider som vanligvis brukes ved fremstillingen av emulsjoner eller emul-sjonsmalingsblandinger kan være til stede i blandingene etter nærværende oppfinnelse i tillegg til polyvinylalkoholen eller stivelses- eller cellulosederivatene. Blant de mange anvendelige kolloider som gir thixotropi i nærvær av titanchelatene skal nev-nes hydroxyethylcellulose, natriumcarboxymethylcellulose, en ammoniakalsk oppløs-ning av aluminiumcarboxymethylcellulose, natriumcarboxymethylstivelse, polyvinylalkohol og alginatene. De filmdannende polymere eller kopolymere kan f. eks. være basert på vinylestere eller på acryl- og methacrylsyreestere eller på styren, acrylonitril eller butadien eller de forskjellige kopolymere i hvilke disse monomere kan være forbundet med eller uten andre umet-téde materialer i mindre mengder. Dessuten kan plastifiseringsmidler være til stede hvis ønsket. According to the present invention, a thixotropic emulsion consisting of an aqueous emulsion of a film-forming polymer or copolymer, which also contains a natural or synthetic water-soluble hydroxyl-containing organic colloid, such as derivatives of starch or cellulose or polyvinyl alcohol, together with 0, 25 to 5 wt. of the titanium chelate based on the weight of the emulsion. Other protective colloids which are usually used in the preparation of emulsions or emulsion paint mixtures may be present in the mixtures according to the present invention in addition to the polyvinyl alcohol or the starch or cellulose derivatives. Among the many applicable colloids which provide thixotropy in the presence of the titanium chelates, mention should be made of hydroxyethyl cellulose, sodium carboxymethyl cellulose, an ammoniacal solution of aluminum carboxymethyl cellulose, sodium carboxymethyl starch, polyvinyl alcohol and the alginates. The film-forming polymers or copolymers can e.g. be based on vinyl esters or on acrylic and methacrylic acid esters or on styrene, acrylonitrile or butadiene or the various copolymers in which these monomers can be connected with or without other unsaturated materials in smaller quantities. In addition, plasticizers may be present if desired.

Thixotrope emulsjonsmalinger som har de ønskede flyteegenskaper kan fremstilles fra thixotrope < emulsjoner etter nærværende- oppfinnelse ved å dispergere hvite eller farvede pigmenter eller strekkmidler i disse på normal måte. Thixotropic emulsion paints which have the desired flow properties can be produced from thixotropic emulsions according to the present invention by dispersing white or colored pigments or stretching agents in them in the normal way.

Oppginnelsen omfatter også en frem-gangsmåte for fremstilling av thixotrope emulsjonsmalinger, hvilken består i å innarbeide i en emulsjonsmaling en mengde på fra y2 til 3 vektspst. av et titanchelat i denne og hvis nevnte maling ikke inneholder noe beskyttelseskolloid eller inneholder et kolloid forskjellig fra et naturlig eller syntetisk vannoppløselig hydroxylholdig organisk kolloid å innarbeide et slikt hydroxylholdig organisk kolloid i denne. The invention also includes a method for the production of thixotropic emulsion paints, which consists in incorporating into an emulsion paint an amount of from y2 to 3 wt. of a titanium chelate therein and if said paint contains no protective colloid or contains a colloid different from a natural or synthetic water-soluble hydroxyl-containing organic colloid to incorporate such a hydroxyl-containing organic colloid therein.

Titanchelatene som kan brukes er av tre typer: 1. Aminoalkoholestere fremstilt ved reaksjonen av isopropyl, 7i-butyl og andre lavmolekylar vekts ortoestere av titansyre med amino-alkoholer, som diethanolamin, tri-isopropanolamin, triethanolamin, me-thyldiethanolamin, [3-amino-ethylethanol-amin, 2-amino-2-ethyl-l,3-propan-diol i hvilke 2 mol av aminoalkoholen anvendes for hvert mol av orto-titanatesteren. Re-aksjonsproduktehe behøver ikke å isoleres, d. v. s. hvert mol av chelatet kan forbli opp-løst i de 2 mol av den frigjorte alkohol. Skjønt den fremstilte alkohol kan separe-res ved destillasjon er de resulterende pro-dukter vanskelige å behandle som meget viskose. Disse estere inneholder to alkoxy-og to amino-alkoxygrupper pr. titanatom. Estere som inneholder tre eller fire amino-alkoxygrupper pr. titanatom kan brukes men slike estere er også meget viskose og vanskelige å behandle. The titanium chelates that can be used are of three types: 1. Amino alcohol esters produced by the reaction of isopropyl, 7i-butyl and other low molecular weight orthoesters of titanium acid with amino alcohols, such as diethanolamine, tri-isopropanolamine, triethanolamine, methyldiethanolamine, [3-amino-ethylethanol-amine, 2-amino-2-ethyl-1,3-propane-diol in which 2 moles of the amino alcohol are used for each mole of the ortho-titanium ester. The reaction product does not need to be isolated, i.e. each mole of the chelate can remain dissolved in the 2 moles of the liberated alcohol. Although the produced alcohol can be separated by distillation, the resulting products are difficult to process as they are very viscous. These esters contain two alkyloxy and two amino-alkyloxy groups per titanium atom. Esters that contain three or four amino-alkoxy groups per titanium atom can be used, but such esters are also very viscous and difficult to process.

De lavere vannoppløselige fettsure salter av aminoalkoholestere, slik som det halve acetatsalt av triethanolamin-2, 1-isopropoxychelat kan også brukes. 2. Vannoppløselige titankomplekser av «-hydroxysyrer og deres barium-, calcium-, strontium-, eller magnesiumsalter, hvis fremstilling er åpenbart i det britiske patent nr. 811.425 og US-patent nr. 2.453.520. 3. Chelater fremstilt fra (3-diketoner og (j-ketonester som kan reagere ved alkoholyse i enolformen med lavere alkylestere av orto-titansyre, og eksempler er reak-sjonsproduktet av 2 mol acetylaceton med 1 mol tetra n-butyltitanat. Reaksjonspro-duktet behøver ikke å isoleres men kan brukes som en oppløsning i alkoholen fremstilt ved alkoholyse av orto-titansyrealkyl-ester. The lower water-soluble fatty acid salts of amino alcohol esters, such as the half-acetate salt of triethanolamine-2,1-isopropoxychelate can also be used. 2. Water-soluble titanium complexes of "-hydroxy acids and their barium, calcium, strontium, or magnesium salts, the preparation of which is disclosed in British Patent No. 811,425 and US Patent No. 2,453,520. 3.
