Definitions

• My invention relates to a process of producing a composition of matter wh ch is especially adapted for impregnatlng or covering textile fabrics but, of course, may be used as well for covering or impregnating any other material or object which it is desired to render waterproof or to protect against the infiuence of'chemicals.
• oil or some other drying or oxidizable ve etable oil, is also used as a basic material or the manufacture of the impregnating material, but the oxidation of the same is performed by means of substances containing chemically bound oxygen. In this manner the process is rendered much quicker and cheaper than the present processes.
• the rocess according'to the present inven-' tionsu stantially conslsts in boiling linseed oil, or some other drying oil, as for instance castor oil, sunflower oil, or the like, separately or mixed with one another, with materials containing the S0 radical, preferably with the acid sludge obtained as a residue in oil refining.
• resin or resin-like organic substances as for instance asphalt, may be mixed with the oils.
• the boilin is continued until the material has turne into a homogeneous, foamless mass, which upon being cooled down, forms a rubber-like substance.
• Jute fabrics impregnated with this material may preferably be used for the manufacture of bags, which will be strong, water-' proof and chemical-proof.
• the impregnating substance produced according to the present invention has the advantage over the pitch asphalt impregnating substances that in consequence of its linoxyn content it does not stick, and is much softer and much more elastic than these materials.
• Another form of the process consists in not fully oxidizing the basic material up to date till the formation of linoxyn; this is attained by adding a smaller amount of oxidizing agent to the basic material than is necescomposition consisting in heating a vegetable sary for fully oxidizing the same, and the impregnation is effected by means of this incompletely oxidized substance.
• the product thus obtained is dried by means of heated air, which operation may be termed a postimpregnation oxidizing.
• siccatives may preferably be added to the material.
• the siccatives accelerate not only the drying up but also the oxidizing process, the same may preferably be employed for this purpose too, even when the oxidizing is finished at the boiling operdrying oil to 180 to 200 C., mixin the said drying oil at this temperature wit mineral oil acid sludge containing the S0 radicle, and boiling the mixture until a homogeneous composition is obtained.
• the acid sludge is only added to an oil or oil-resin mixture of high temperature, one over 180 to 200 C. only, because in the contrary case the oxidation process is not carried out to the required extent, the material is formed into lumps, and it becomes coked on the walls of the cauldron.
• the impregnation with the composition obtained may be effected in any known manner. If the composition is rolled in liquid or in plastic form on one side of the textile fabric a material will be obtained which will permit the manufacture of bags covered with a protecting layer on the inside only, which will prevent t e bag from deteriorating under the influence of caustic materials. In this case the fabric on the outside retains its original appearance.
• composition described mineral oils may be added to the material during or after the oxidation process.
• a process for manufacturing a linoleum composltion consisting in mixing a vegetable drying oil with mineral oil acid sludge con" taining the S0 radicle, and boiling the mixture.
• a process for manufacturing a linoleum composition consisting in heating a vegetable drying oil to 180-200 G, mixmg the said. drying oil at this temperature with mineral oil acid sludge containing the 550. radicle, and boiling the mixture.
• a process for manufacturing a linoleum composition consisting in mixing a vegetable drying oil with mineral oil acid sludge containing the S0 radicle, and boiling the mixture until a homogeneous composition is obtained.
