Description
Por rensning av overflater, f.eks. lakkerte deler eller tekstiler har det hittil blitt anvendt midler, som enten oppløser smusstoffene eller gjør dem fuktbare med vann, således at disse stoffer kan fjernes med vandige væsker. Oppløsnings-midlene inneholder ofte hydrofoberte uorganiske eller organiske stoffer med stor overflate til absorpsjon av fettlignende smuss-stoffer. Slike stoffer med stor overflate er eksempelvis kise-syregeler eller polyuretanskumpulvere. Spundne eller ekstru-derte kunststoff-fibre med fin titer har vist seg mindre egnet, da den virksomme overflate av disse fibre er for liten og fibrene i vandige systemer har en for høy overflatespenning. Pore cleaning of surfaces, e.g. lacquered parts or textiles, agents have been used up to now, which either dissolve the soiling substances or make them wettable with water, so that these substances can be removed with aqueous liquids. The solvents often contain hydrophobic inorganic or organic substances with a large surface area for the absorption of fat-like dirt substances. Such substances with a large surface area are, for example, silicic acid gels or polyurethane foam powders. Spun or extruded plastic fibers with a fine titer have proven less suitable, as the effective surface of these fibers is too small and the fibers in aqueous systems have too high a surface tension.
Hyppig anvendes også skumrensemidler, som baserer seg på vandige tensidoppløsninger. Ved hjelp av disse midler lysgjøres riktignok for det meste flekker, imidlertid utbredes de samtidig ved utflytning til flere ganger deres opprinnelige størrelse. Foam cleaners, which are based on aqueous surfactant solutions, are also frequently used. With the help of these means, it is true that spots are mostly lightened, however, they are spread at the same time by spreading to several times their original size.
Det er nå funnet at bestemte polyolefinfibre, så-kalte polyolefin-fibrider, fremstillet ved avspennings fordampning av polyolefinoppløsninger eller -emulsjoner, egner seg ut-merket til fjerning av flekker og til rensning av tekstiler. It has now been found that certain polyolefin fibres, so-called polyolefin fibrids, produced by relaxation evaporation of polyolefin solutions or emulsions, are excellently suited for removing stains and for cleaning textiles.
Oppfinnelsens gjenstand er således en fremgangsmåte til rensning av overflater ved påføring av et absorberende stoff-holdig rensemiddel og fjerning av rensemidlet sammen med absor-bert smuss, idet fremgangsmåten erkarakterisert vedat det anvendes et rensemiddel som inneholder 0,05 til 3j0 vekt$, referert til polyolefinet av en overflateaktiv hydrofil forbindelse og som absorberende stoff, polyolefinfibrider med en klassifisert fiberlengde fra 0,05 til 3 mm og en overflate ifølge BET-metoden på mer enn 1 m /gram. The object of the invention is thus a method for cleaning surfaces by applying an absorbent substance-containing cleaning agent and removing the cleaning agent together with absorbed dirt, the method being characterized by using a cleaning agent containing 0.05 to 3j0 by weight, referred to the polyolefin of a surface-active hydrophilic compound and as absorbent, polyolefin fibrids with a classified fiber length from 0.05 to 3 mm and a surface according to the BET method of more than 1 m /gram.
Oppfinnelsens gjenstand er videre rensemidlet anvendt i overnevnte fremgangsmåte samt anvendelsen av. nevnte poly- The object of the invention is furthermore the cleaning agent used in the above-mentioned method as well as the use of. said poly-
olefinfibrider i sliké midler. olefin fibrides in such agents.
Polyolefinfibridene som skal anvendes for fremgangsmåten ifølge oppfinnelsen består til 97 til 99,95 vekt#, fortrinnsvis 99 til 99, 9 vekt% av et polyolefin og til 0,05 til 3 vekt%, fortrinnsvis 0,1 til 1,0 vekt% av en overflateaktiv hydrofil forbindelse. The polyolefin fibrides to be used for the method according to the invention consist of 97 to 99.95% by weight, preferably 99 to 99.9% by weight of a polyolefin and 0.05 to 3% by weight, preferably 0.1 to 1.0% by weight of a surfactant hydrophilic compound.
Som polymere egner det seg homo- og kopolymere As polymers, homo- and copolymers are suitable
av olefiner, fortrinnsvis anvendes polymere av etylen, propylen og/eller'buten-1, slik de fremstilles etter kjente lavtrykkfrem-gangsmåter. Egnet er også kopolymere av etylen eller propylen med mindre mengder andre monomere, f.eks. vinylestere eller akrylsyrederivater. Spesielt foretrekkes imidlertid lavtrykkpolyetylen. of olefins, polymers of ethylene, propylene and/or butene-1 are preferably used, as they are produced according to known low-pressure methods. Also suitable are copolymers of ethylene or propylene with smaller amounts of other monomers, e.g. vinyl esters or acrylic acid derivatives. However, low-pressure polyethylene is particularly preferred.
Den overflateaktive hydrofile forbindelse er fortrinnsvis høymolekylær. Eksempler er stivelse, metylcellulose, karboksymetylcellulose, polyalkylenoksyder, polyvinylalkohol. Spesielt foretrukket er polyvinylalkoholer med en forsåpningsgrad fra 60 til 99, 9% og en oppløsningsviskositet (4$ i vann ved 20°C) fra 4 til 90 cP. The surface-active hydrophilic compound is preferably of a high molecular weight. Examples are starch, methylcellulose, carboxymethylcellulose, polyalkylene oxides, polyvinyl alcohol. Particularly preferred are polyvinyl alcohols with a degree of saponification from 60 to 99.9% and a solution viscosity (4$ in water at 20°C) from 4 to 90 cP.
Por fremstilling av polyolefinfibrider er det Por the production of polyolefin fibrids it is
kjent forskjellige fremgangsmåter, eksempelvis utdysing av en overopphetet polymeroppløsning eller utdysing av en overopphetet emulsjon av en polyolefinoppløsning og en vandig oppløsning av den overflateaktive hydrofile forbindelse. Pibridene har en 'spesifikk overflate (ifølge BET-metoden) på mer enn 1 m o/g, fortrinnsvis 1 - 100 m ? /g, spesielt 5 - 25 m 2/g og en klassifisert fiberlengde ifølge TAPPI-norm T 233 SU 64 fra 0,05 til 3 mm, fortrinnsvis 1,0 til 2,0 mm. De spesielt foretrukkede polyolefinfibrider fremstilles ved hjelp av avspenningsfordampning av en overopphetet emulsjon fra en polyolefinoppløsning i en lavere hydrokarbon og en vandig oppløsning av den overflateaktive hydrofile forbindelse, eksempelvis på følgende måte (sammenlign DOS2.411.589)'. known different methods, for example spraying a superheated polymer solution or spraying a superheated emulsion of a polyolefin solution and an aqueous solution of the surfactant hydrophilic compound. The peptides have a 'specific surface (according to the BET method) of more than 1 m o/g, preferably 1 - 100 m ? /g, in particular 5 - 25 m 2 /g and a classified fiber length according to TAPPI standard T 233 SU 64 from 0.05 to 3 mm, preferably 1.0 to 2.0 mm. The particularly preferred polyolefin fibrids are produced by flash evaporation of a superheated emulsion from a polyolefin solution in a lower hydrocarbon and an aqueous solution of the surface-active hydrophilic compound, for example in the following manner (compare DOS2,411,589)'.
Et 250 liters kar utstyrt med en rører og en utløps-ventil, som over en ledning er forbundet med en dyse, som fører inn i et avspenningskar fylles med 9>6 kg polyetylen (RSV 1,4 dl/ g, MFI 5 j 58)3 120 liter vann 96 g polyvinylalkohol (viskositet 4,6 til 6 cP 4$-ig i vann ved 20°C, forsåpningsgrad 98,5 til 100 mol%) og'120 liter heksan. Deretter lukkes karet og karinnholdet oppvarmes under omrøring til 150°C og holdes ca. 2\ time ved denne temperatur. Derved oppnås et trykk på 12,3 kg/cm . Etter at polyetylenet har oppløst seg og karinnholdet har gått over i en emulsjon åpnes utløpsventilen av emulsjonen, haes ut i avspenningskaret i samme grad som ett til dette krav til-sluttet vakuumpumpe, frasuger de frigjorte damper og kan opp-rettholde et trykk på ca. 200 mm Hg. De dannede fibre deig-dannes med vann, haes 7 ganger gjennom en skiveraffinerer og deretter adskilles ved sentrifugering fra vann. Fibrene har. A 250 liter vessel equipped with a stirrer and an outlet valve, which is connected via a line to a nozzle, which leads into a relaxation vessel, is filled with 9>6 kg of polyethylene (RSV 1.4 dl/g, MFI 5 j 58 )3 120 liters of water 96 g of polyvinyl alcohol (viscosity 4.6 to 6 cP 4$-ig in water at 20°C, degree of saponification 98.5 to 100 mol%) and'120 liters of hexane. The vessel is then closed and the contents of the vessel are heated with stirring to 150°C and held for approx. 2\ hours at this temperature. A pressure of 12.3 kg/cm is thereby achieved. After the polyethylene has dissolved and the vessel contents have turned into an emulsion, the outlet valve of the emulsion is opened, it is taken out into the relaxation vessel to the same extent as a vacuum pump connected to this requirement, they suck out the released vapors and can maintain a pressure of approx. 200 mm Hg. The formed fibers are dough-formed with water, passed 7 times through a disc refiner and then separated from water by centrifugation. The fibers have
en spesifikk overflate ifølge BET-metoden på 8,2 m /g og en klassifisert fiberlengde ifølge TAPPI-norm T 233 SU 64 på 0,9 mm. a specific surface according to the BET method of 8.2 m/g and a classified fiber length according to the TAPPI standard T 233 SU 64 of 0.9 mm.
Egnede polyolefinfibrider kan også fremstilles etter fremgangsmåten ifølge DOS 2.249.604. BET-metoden omtales av Brunauer, Emmet og Teller i J. Am. Chem. Soc. 60, 309 (1938). Suitable polyolefin fibrids can also be produced according to the method according to DOS 2,249,604. The BET method is discussed by Brunauer, Emmet and Teller in J. Am. Chem. Soc. 60, 309 (1938).
Til de polymere kan det settes fyllstoffer eller pigmenter, f.eks. leirjord, kalsiumkarbonat, dolomit eller titandioksyd før avspennings fordampning av polymerblandingen.. Fortrinnsvis anvendes hydrofoberte fyllstoffer eller pigmenter. Som hydrofoberingsmiddel egner det seg f.eks. fettsyrer, fett-syreaminer og - amider eller silikoner. Fillers or pigments can be added to the polymers, e.g. clay soil, calcium carbonate, dolomite or titanium dioxide before relaxation evaporation of the polymer mixture. Hydrophobized fillers or pigments are preferably used. As a hydrophobic agent, it is suitable, e.g. fatty acids, fatty acid amines and - amides or silicones.
For gjennomføring av fremgangsmåten ifølge oppfinnelsen anvendes polyolefinfibridene enten i tørr eller fuktig form, eksempelvis i vannfuktig form, hvori fibrene fremkommer i den foretrukkede avspennings fordampnings fremgangsmåten. Fibrene kan imidlertid også før anvendelsen oppslemmes i vanlige rense-midler, eksempelvis organiske oppløsningsmidler som isopropanol, perkloretylen, aceton eller vann. For carrying out the method according to the invention, the polyolefin fibers are used either in dry or moist form, for example in water-moist form, in which the fibers appear in the preferred relaxation evaporation method. However, the fibers can also be slurried in common cleaning agents, for example organic solvents such as isopropanol, perchlorethylene, acetone or water, before use.
Fibrene eller deres oppslemning påstrøs på den tilsmussede overflate eller påstrykes og deretter fordeles godt, f.eks. ved børsting og innrives. Etter oppsugning av tilsmus-ningen fjernes rensemidlet, f.eks.'børstes av eller fjernes med en støvsuger. Hvis nødvendig Kan fremgangsmåten gjentas, eventuelt under endring av det anvendte oppløsningsmiddel. The fibers or their slurry is sprinkled on the soiled surface or brushed on and then spread well, e.g. by brushing and is filed. After the dirt has been absorbed, the cleaning agent is removed, for example brushed off or removed with a vacuum cleaner. If necessary, the procedure can be repeated, possibly changing the solvent used.
Likeledes er det mulig å anvende fibrene i form av papir, som helt eller overveiende består av fibrider, mens den øvrige del består av vanlige cellulosefibre. Disse papir kan f.eks. ved tørre flekker på forhånd impregneres med oppløsnings-middel eller vann. For fjerning av flekker påtrykkes disse papir enkelt resp. de tilsmussede steder gnis med papiret. Det er også mulig først å fukte en flekk med vann eller et oppløs-ningsmiddel og deretter å oppsuge fuktigheten og tilsmussingen med rensemidlet ifølge oppfinnelsen. Den gunstigste anvendelse retter seg eventuelt etter typen av tilsmussing. Likewise, it is possible to use the fibers in the form of paper, which consists entirely or predominantly of fibrides, while the other part consists of ordinary cellulose fibers. These papers can e.g. in the case of dry spots, pre-impregnated with solvent or water. To remove stains, these are simply printed on paper or the soiled places are rubbed with the paper. It is also possible to first moisten a stain with water or a solvent and then to absorb the moisture and soiling with the cleaning agent according to the invention. The most favorable application may depend on the type of soiling.
I fremgangsmåten ifølge oppfinnelsen kan fibridene også anvendes sammen med skumrensemiddel. I dette tilfellet virker fibrene som høyaktive smussabsorberere. In the method according to the invention, the fibrides can also be used together with a foam cleaning agent. In this case, the fibers act as highly active dirt absorbers.
Rensemidlet ifølge oppfinnelsen består i det vesent-lige av de overnevnte polyolefinfibrider. Piberinnholdet kan være 100 vekt^-ig, når fibrene anvendes i tørr tilstand, det kan imidlertid også være mindre når fibrene anvendes fuktig eller i form av en oppslemning, minst imidlertid 5 vekt%. De andre bestanddeler av rensemidlet ifølge oppfinnelsen kan være vann i en mengde fra 0 til 95 vekt$, fortrinnsvis 10 til 60 vekt% eller organiske oppløsningsmidler i en mengde fra 0 til 80 vekt%, fortrinnsvis 20 til 60 vekt$. Slike organiske oppløs-ningsmidler kan ikke bare være de vanligvis i rensetreknikken anvendte oppløsningsmidler, som eksempelvis isopropanol, perkloretylen eller aceton, men også fettsyreestere eller hydrokar-boner. The cleaning agent according to the invention essentially consists of the above-mentioned polyolefin fibrids. The fiber content can be 100% by weight when the fibers are used in a dry state, but it can also be less when the fibers are used moist or in the form of a slurry, but at least 5% by weight. The other components of the cleaning agent according to the invention can be water in an amount from 0 to 95% by weight, preferably 10 to 60% by weight, or organic solvents in an amount from 0 to 80% by weight, preferably 20 to 60% by weight. Such organic solvents can not only be the solvents usually used in the cleaning technique, such as isopropanol, perchlorethylene or acetone, but also fatty acid esters or hydrocarbons.
Fremgangsmåten ifølge oppfinnelsen og midlet ifølge oppfinnelsen egner seg fremfor alt til rensning av tekstiler, som bare overflatelig kan behandles, som eksempelvis tetter veggbekledninger', møbeltrekk eller pels. De kan imidlertid også anvendes til flekkfjerning av yttertøy. En spesiell fordel består i at ved den høye absorpsjonsevne for lipofile stoffer unngås sterkt den ellers ofte opptredende kantdannelse på flekkene. The method according to the invention and the agent according to the invention are above all suitable for cleaning textiles which can only be treated superficially, which for example seal wall coverings, upholstery or fur. However, they can also be used to remove stains from outerwear. A special advantage consists in the fact that the high absorption capacity for lipophilic substances strongly avoids the otherwise often occurring edge formation on the stains.
Videre egner midlet ifølge oppfinnelsen seg, spesielt til rensning av lakkerte, ripefølsomme flater, som f.eks. bilkarosserier, forkrummede deler og møbler. Furthermore, the agent according to the invention is particularly suitable for cleaning varnished, scratch-sensitive surfaces, such as e.g. car bodies, bent parts and furniture.
For spesialtilfelle, f.eks. til avbéisning, kan fibrene også blandes med syrer eller alkalier, f.eks. med inn-til 90 vekt% fortynnet saltsyre eller fortynnet kalilut. Eksempe1. For special cases, e.g. for de-icing, the fibers can also be mixed with acids or alkalis, e.g. with up to 90% by weight diluted hydrochloric acid or diluted potassium hydroxide. Example 1.
Et teppe med polyamid-flor, som hadde vært i bruk noen tid og var tilsmusset, ble tilsmusset med forskjellige stoffer i to parallelle rekker og deretter den ene rekke behand-let med et vanlig renseskum på tensidbasis og den andre rekke med et rensemiddel ifølge oppfinnelsen. For fremstilling av rensemidlet'ble lavtrykkpolyetylen med en tetthet på 0,958 og en smelteindeks MFI 190/5 på 22 g/10 min. forarbeidet etter overnevnte fremgangsmåte (eksempel 1 i DOS 2.411.589) til fibre av en midre lengde på 1,55 mm og en BET-overflate på 10 m p/g. Til forskjell fra overnevnte angivelser ble poly-vinylalkoholen bare anvendt i en mengde på 0,2 vekt%, referert til polyetylen. A carpet with polyamide pile, which had been in use for some time and was soiled, was soiled with different substances in two parallel rows and then one row was treated with a conventional surfactant-based cleaning foam and the other row with a cleaning agent according to the invention . For the production of the cleaning agent, low-pressure polyethylene with a density of 0.958 and a melt index MFI 190/5 of 22 g/10 min was used. processed according to the above-mentioned method (example 1 in DOS 2,411,589) into fibers of a mean length of 1.55 mm and a BET surface area of 10 m p/g. In contrast to the above-mentioned indications, the polyvinyl alcohol was only used in an amount of 0.2% by weight, referred to polyethylene.
De vannfuktige fibre, som omtrent inneholdt 50 vekt% vann ble strødd på teppet og godt fordelt og innrevet ved børsting. Deretter ble fibrene fjernet med en støvsuger. Smussrenéemidlet ble avbørstet som nevnt ovenfor og etter tørk-ning likeledes avsuget. I tilfellet renseskummet fremkom i alle tilfeller en økning av flekken til 3 til 4 ganger dens opprinnelige,størrelse, mens ved rensemidlet ifølge oppfinnelsen var det å iaktta bare uvesentlige forstørrelser. Av tabellen fremgår forsøksresultatene. The water-moist fibers, which contained approximately 50% water by weight, were sprinkled on the carpet and well distributed and torn up by brushing. The fibers were then removed with a vacuum cleaner. The dirt remover was brushed off as mentioned above and, after drying, also vacuumed. In the case of the cleaning foam, an increase of the stain to 3 to 4 times its original size appeared in all cases, while with the cleaning agent according to the invention, only insignificant enlargements were to be observed. The table shows the test results.
