Semi-fluid lubricant for oil level lubrication of looms, condensed with lithium soaps, characterised in that it contains 3-10% by weight of lithium soaps of long-chain fatty acids, preferably 12-hydroxystearic acid, 45-96% by weight of a known synthetic lubricating oil, preferably polyalkoxy glycol or ester oil with the viscosity exceeding 50mm<2>/s in 50 degrees C, 0-49% by weight of mineral oil with the viscosity exceeding 50mm<2>/s in 50 degrees C, 0.5-3% by weight of additives improving lubricity and anti-corrosive properties, preferably lead 2-amyl-2-thiocarbamate or lead alkyl aryl sulfonate.2. Method of producing semi-liquid lubricate for oil level lubrication of looms, condensed with lithium soaps, characterised in that long-chain fatty oils, preferably 12-hydroxystearic acids, are dissolved in a synthetic lubricating oil, preferably in polyalkoxy glycol or ester oil, and they are saponified by means of a saturated aqueous solution of lithium hydroxide at the temperature of 30-80 degrees C, and further, after the mixture is heated to the temperature of 120-130 degrees C and the water is distilled off, the additives improving lubricity and anti-corrosive properties, preferably lead 2-amyl-2-thiocarbamate or lead alkyl aryl sulfonate, dissolved in mineral oil with the viscosity exceeding 50mm<2>/s in 50 degrees C or in synthetic oil, preferably polyalkoxy glycol or ester oil with the viscosity exceeding 50mm<2>/s in 50 degrees C, are entered into the mixture, and further the semi-fluid lubricate is mixed until it becomes a homogenous substance and at the same time it is cooled until it reaches ambient temperature.

Description

The subject of the invention is a semi-fluid grease for the lubrication of stump looms, in particular of STB gripper looms, thickened with polyurethane soaps, and a method of producing semi-fluid grease for the lubrication of stump looms thickened with rope soaps.

The methods of producing plastic greases containing molybdenum biscuits, known from Polish patent specifications Nos. 101 989, 102 040, 102 041, 121 579, are based on a mineral oil of the naphthenic type thickened with Ciluwymi soaps obtained by saponification of 11-hydroxytaaceric acid with lithium hydroxide. In order to increase the corrosion protection of metal surfaces lubricated with these smaramm, special inhibitors have been introduced to inhibit the corrosive activity of moUbden's bisque, such as alkaline eCykylaryroθullonlates or alkaline earth eaftrsulphonlates or polyalkenes and alkenans containing 1,2 alkenophylts ireazole.

The grease for cylindrical roller bearings known from the German patent specification No. 2,232,201 contains mineral oil, a mixture of lye soaps of higher fatty acids, an antioxidant and possibly a high viscosity additive. Nitomast known from US Pat. No. 3,939,082 6mar contains hydrotreated naphthatene oil or hylrocracovene paraffin oil 0-1% lithium stearate, 0.02-2% neutral barium sulphonate and 0.1-5% zinc luaeklloduutiphosphate. A known from French patent documents Nos. 2 212 423 and 2 255 374 lithium greases contain as a thickening agent 5 - 20% by weight of lithium hydroxysteeric acid soap and 0.1 - 3% by weight of lithium tetraborate or fatigue of fatty acid hydroxyl fatty acid soap by 12 - 24 carbon atoms and a M4 dicarboxylic acid soap with 2-12 carbon atoms, such as azeC.aenouy acid.

Known lithium greases prepared based on the base oil of mineral origin, regardless of the percentage and the composition of soap used to lubricate kąpisoowsgo boxes driving and functional looms do not comply 9po9ób satisfactorily all the requirements central 9marującemu primarily characterized her ^{Si zb} y ^t low resistance on oxidation processes. For these reasons, mineral oils are used for bath lubrication of the looms, which, with the construction solutions used, come out of the systems, causing increased wear of rubbing elements, as well as the formation of stains that are difficult to remove on the processed textile raw materials.

The aim of the invention is to eliminate these disadvantages and, for technical reasons, to develop a production method and a semi-fluid grease thickened with base soap, which has good lubricating functions and eliminates the possibility of escaping from the lubrication bath lubrication systems.

Semi-fluid grease for lubricating kąpleoowego looms, according to the invention contains 3 - 1C5u by weight of soap leaves ^ Outgoing higher fatty acids, preferably 12-hydroxystearic acid, 45 - y6% by weight of known synthetic lubricating oil, preferably an oil polial-ooksy ^ i ^ o ^ acid ^{l b} u ester of ^p le co ^{TARGET p} owyżs ^{j 5} 0 «im ² / s at 50 ° C - ⁴⁹ ° C in Χ in mineral oil chi ^ o ^ pkości above 5H mn ² / s at 5O ° C, 0.5 13% additives to improve lubricity and anti-corrosive properties, preferably lead fatty acid and oxybamate or lead acid sulfonate.

The subject of the invention is characterized by good lubricating properties, corrosion resistance, high resistance to oxidation processes, and its consistency makes it a sealant and protects against leakage from rubbing knots on the loom and against bland staining of the processed textile raw material.

The invention will be elucidated in more detail in the following examples of the method for producing a bath lubricant for STB looms, which do not exhaust the applicability of the invention.
