Description
Uppfinnare: K. H. Magnusson och H. F. Sander. Inventors: K. H. Magnusson and H. F. Sander.
Blandningar och lOsningar innehallande linolja och nitrocellulosa anvandes for de mest skilda andamal, sarskilt for bestrykning, inom lackindustrien saint for appretering och inpregnering av textilier. Linoljans formaga att lOsa nitrocellulosa är begransad. Det Si emellertid ka.nt (jfr amerikanska patentskriften 2 059 259), att en linolja, raffinerad enligt de -vanliga metoderna, är obegransat blandbar med vanliga oljelOsande medel, säsoin terpentinolj a, koltetraklorid, petroleumeter o. s. v., men ol5slig i metyl- och etylalkohol. Genom luftblasning vid 10-67° C i 200 —300 timmar far en sadan linolja fOrmagan att losa atminstone sin egen vikt alkohol, men den minskar i losligbet i de vanliga oljelosande medel, sa att den endast formar losa sin egen vikt vanliga, oljelosande _medel. Den luftblasta linoljan blir i detta tillstand bland-bar med i blandningen av hog- och lagkokande losningsmedel lost nitrocellulosa. Mixtures and solutions containing linseed oil and nitrocellulose were used for a variety of purposes, especially for coating, in the paint industry for the finishing and impregnation of textiles. The linseed oil's shape to 10 nitrosellulose is limited. However, it is possible (cf. U.S. Pat. No. 2,059,259) that a linseed oil, refined according to the usual methods, is immiscibly miscible with common oil-soluble agents, such as turpentine oil, carbon tetrachloride, petroleum ether, . By blowing air at 10-67 ° C for 200-300 hours, such a linseed oil is able to dissolve at least its own weight of alcohol, but it reduces the solubility in the usual oil-releasing agents, so that it only forms to release its own weight of ordinary, oil-releasing agents. . The air-blasted linseed oil in this state becomes miscible with the nitrocellulose lost in the mixture of high- and low-boiling solvents.
Foreliggande uppfinning avser ett nytt slags blandningar och losningar ay linolja och nitrocellulosa. Det har namligen visat sig att, nar linoljan raffineras pa ett sarskilt satt ,och sedan behandlas med luft, syre och syrehaltiga gaser, denna linolja far formaga att losa nitrocellulosa mycket Mare an vanlig linolja. Blandningarna och losningarna enligt uppfinningen innehalla sadan linolja, vilken raffinerats medelst utspadd svavelsyra (35— 80-procentig), medan linolj an hittills raffinerats medelst koncentrerad svavelsyra (96- procentig). Den med utspadd svavelsyra raffinerade linoljan luftblases sedan vid rumstemperatur eller vid hogre temperatur, dock lampligen joke Over 10 G och ej langre an 60 timmar, foretradesvis 24-60 timmar. The present invention relates to a new kind of mixtures and solutions of linseed oil and nitrocellulose. It has been found that when linseed oil is refined in a special way, and then treated with air, oxygen and oxygen-containing gases, this linseed oil is capable of dissolving nitrocellulose much more than ordinary linseed oil. The mixtures and solutions according to the invention contain such linseed oil, which has been refined by means of dilute sulfuric acid (35-80%), while linseed oil has hitherto been refined by means of concentrated sulfuric acid (96%). The linseed oil refined with dilute sulfuric acid is then air blown at room temperature or at a higher temperature, however, suitably joke Over 10 G and no longer than 60 hours, preferably 24-60 hours.
Den genom sattet enligt uppfinningen erhallna oljan Sr Oven betydligt overlagsen den i amerikanska patentskriften 2 059 259 beskrivna. Den enligt uppfinningen behandlade olj an kan namligen anvandas vid en viskositet av 1 poise vid 50° C, under det oljan enligt namnda amerikanska patenskrift maste bibringas en hog -viskositet, sS att den Sr nara gelateringsstadiet eller redan Sr gelatinerad. Den enligt uppfinningen tillsammans med nitrocellulosa anvanda linoljan Sr alltsa en linolja, som raffinerats under anvandning av utspadd svavelsyra samt luftblasts och som i huvudsak overensstammer med vanlig linolja, men skiljer sig fran denna genom okadlosningsfOrmaga for nitrocellulosa. Amerikanska patentskriften 2 293 038 beskriver daremot bestrykningsmedel, -vilka utom nitrocellulosa innehalla modifieringsprodukter av linolja. Dessa modifieringsprodukter utvinnas genom inverkan av polara fOreningar, bland vilka aven namnas oorganiska syror, pa oljan, varvid modifieringsmedlen anvandas i vattenfritt tillstand (jfr sid. 6, rad 46-48 1 den amerikanska patentskriften). Vid oljornas modifiering enligt uSiunda patentskrift Sr det uppenbarligen fraga om betydligt storre forandringar hos linoljans molekyler an som Sr fallet vid linolj ails raffinering enligt foreliggan de ansiikan, dar den fOretages med utspadd svavelsyra och pafoljande lufthlasning. Darvid forbliva linoljans egenskaper i huvudsak oforandrade, endast dess losningsformaga for nitrocellulosa iikar. Att anvanda en sa tjock olja som i den amerikanska patentskriften medfor, att stora mangder losningsmedel erfordras for att nedbringa viskositeten. Den luftblasta olja, som Sr framstalld enligt den nya metoden, fOrmar i motsats till luftblast olja, som har framstallts enligt den amerikanska inetoden, att losa alkoholfuktat boinullskrut utan tillsats av lOsningsmedel. Blandningen av olja och bomullskrut kan spadas med denaturerad sprit, ett avsevart billigare spadmedel an den blandning av butylacetat, butanol, etylacetat, alkohol och toluol, som det amerikanska patentet foreskriver. The oil Sr Oven obtained by the process of the invention is substantially superior to that described in U.S. Pat. No. 2,059,259. Namely, the oil treated according to the invention can be used at a viscosity of 1 poise at 50 ° C, while the oil according to the said U.S. patent specification must be imparted a high viscosity, such that it is near the gelation stage or already Sr gelatinized. The linseed oil used according to the invention together with nitrocellulose is thus a linseed oil, which has been refined using dilute sulfuric acid and air blasts and which essentially corresponds to ordinary linseed oil, but differs from it by the nitrocellulose dissolving capacity. U.S. Pat. No. 2,293,038, on the other hand, discloses coatings which, in addition to nitrocellulose, contain modifying products of linseed oil. These modifiers are recovered by the action of polar compounds, also called inorganic acids, on the oil, the modifiers being used in the anhydrous state (see page 6, lines 46-48 of the U.S. Patent). In the modification of the oils according to uSiunda patent specification, it is obviously a question of significantly larger changes in the molecules of the linseed oil than is the case with the refining of linseed oil according to the present application, where it is carried out with dilute sulfuric acid and subsequent aeration. In this case, the properties of the linseed oil remain essentially unchanged, only its release form for nitrocellulose. Using such an oil as in the U.S. patent specification means that large amounts of solvent are required to reduce the viscosity. The air-blasted oil, which is produced according to the new method, forms, in contrast to the air-blasted oil, which has been produced according to the American method, to dissolve alcohol-moistened bean-wool powder without the addition of solvents. The mixture of oil and cotton powder can be sprayed with denatured alcohol, a considerably cheaper spray than the mixture of butyl acetate, butanol, ethyl acetate, alcohol and toluene prescribed by the US patent.
Den sarskilda overlagsenheten av den enligt uppfinningen raffinerade och luftblasta linoljan sasom bestandsdel av blandningar och losningar innehallande linolja och nitrocellulosa beror p5. foljande egenskaper hos denna linolja: Den nya, blasta oljan or obegransat blandbar med nitrocellulosalack och fOrmar 2-- — i blandning, s. k. kombinationslack, icke endast ersiitta hartser och mjukningsmedel utan aven en stor del av losningsmedlen. Den nod-vdndiga mangden losningsmedel kan t. o. m. i stor utstrackning erslittas med denaturerad sprit eller terpentin, t. ex. svensk sulfatterpentin. Den nya, blasta oljan format', som ovan namnts, liven 18sa llisningsmedelsfri, alkoholfuktat nitrocellulosa. Om den nya oljan lases till en viskositet av 10 poise vid 50° C och blandas med hOgviskos nitrocellulosa, erhiiller man ett utrarkt medel for appretur och irnpregnering av vavnader. Till ytterligare tydliggorande av uppfinningen lamnas fi31- jan exempel. The particular overlay unit of the refined and air-blasted linseed oil according to the invention as a constituent of mixtures and solutions containing linseed oil and nitrocellulose depends on p5. the following properties of this linseed oil: The new, blasted oil is indefinitely miscible with nitrocellulose lacquer and forms 2-- - in a mixture, so-called combination lacquer, not only substituted resins and plasticizers but also a large part of the solvents. The required amount of solvent can even be largely worn with denatured alcohol or turpentine, e.g. Swedish sulfatterpentine. The new, blast oil formate ', as mentioned above, lives 18sa solvent-free, alcohol-moistened nitrocellulose. If the new oil is read to a viscosity of 10 poise at 50 ° C and mixed with high viscosity nitrocellulose, a dehydrating agent is obtained for finishing and impregnating tissues. To further clarify the invention, the following examples are left.
Exempel 1. 100 kg kallpressad linoija raffineras med 3 kg 72-procentig svavelsyra. Den pa sa salt raffinerade linoljan genomblases med luft i 24 timmar vid 100° C, varvid jodtalet fir 150, hydroxyltalet minst 45, peroxidtalet 350, ffirgtalet 18, viskositeten 1 poise vid 50' C och torktiden med sickativ 5 timmar. Derma olja formar losa alkoholfuktat nitrocellulosa av typen Bofors VF 2. En losning av 1 del VF 2-pasta i 1 del olja kan splidas med 1 del 96-procentig etylalkohol eller med 1 del sulfatterpentin. For aft blandningen skall bli fullt klar, bor 1-2 c,10 etylacetat tillsattas. Andra losningsmedel kunna givetvis anvandas. Ett kombinationslack, bestfiende av 15 viktdelar av denna olja (sickativerad med 0,3 % blymetall och 0,05 % koboltmetall), 15 viktdelar alkoholfuktad VF 2-pasta, 25 viktdelar butylacetat, 22,s viktdelar bensin 100— 140°, 22,5 viktdelar xylol och 2 viktdelar dibutylftalat, har sfirskilt goda lacktekniska egenskaper. Example 1. 100 kg of cold-pressed linoija are refined with 3 kg of 72% sulfuric acid. The linseed oil refined on such a salt is blown through with air for 24 hours at 100 ° C, the iodine value being 150, the hydroxyl number at least 45, the peroxide number at least 350, the color number 18, the viscosity 1 poise at 50 ° C and the drying time with siccative 5 hours. This oil forms a solution of alcohol-moistened nitrocellulose of the type Bofors VF 2. A solution of 1 part VF 2 paste in 1 part oil can be split with 1 part 96% ethyl alcohol or with 1 part sulfurate pentine. Before the mixture is completely clear, 1-2 c, 10 ethyl acetate should be added. Other solvents can of course be used. A combination varnish, consisting of 15 parts by weight of this oil (saturated with 0.3% lead metal and 0.05% cobalt metal), 15 parts by weight of alcohol-moistened VF 2 paste, 25 parts by weight of butyl acetate, 22 parts by weight of gasoline 100-140 °, 22, 5 parts by weight of xylene and 2 parts by weight of dibutyl phthalate, have particularly good paint technical properties.
Exempel 2. Linolja, raffinerad enligt exempel 1, genomblithes med luft vid 100° C i 50-60 timmar till viskositet 10 poise vid 50° C och peroxidtal 400-500, formar losa hogviskos nitrocellulosa av typen Bofors VF 1000. Losningen kan spadas med etylacetat, etylalkohol eller sulfatterpentin, varvid ett utmarkt appreterings- och impregneringsmedel for textilier erhalles. Andra losningsmedel kunna givetvis anvandas. En kombination, bestfi.ende till 50 % av olja, framstalld enligt detta exempel (sickativerad med 0,3 % blymetall och 005 % koboltmetall), 40 % VF 1000-pasta och 10 % etylacetat, liar speciellt goda appreterings- och impregneringsegenskaper for textilier. Example 2. Linseed oil, refined according to Example 1, is permeated with air at 100 ° C for 50-60 hours to a viscosity of 10 poise at 50 ° C and a peroxide value of 400-500, forms loose high viscose nitrocellulose of the type Bofors VF 1000. The solution can be spade with ethyl acetate, ethyl alcohol or sulphate turpentine, whereby an excellent sizing and impregnating agent for textiles is obtained. Other solvents can of course be used. A combination, consisting of 50% of oil, prepared according to this example (saturated with 0.3% lead metal and 005% cobalt metal), 40% VF 1000 paste and 10% ethyl acetate, has particularly good finishing and impregnating properties for textiles. .
