Abstract

1444347 Lubricating the inside of tyres DUNLOP Ltd 22 Aug 1973 [2 Sept 1972] 40824/72 Heading B2E [Also in Divisions B7 and C5] A gelled composition coated on at least a portion of the interior surface of a pneumatic tyre to lubricate regions which contact when the tyre is run deflated, comprises a liquid lubricant having a boiling point above 160‹C and preferably above 200‹C and a gelling agent therefor. Preferably the composition will not freeze at temperatures above -50‹C. The composition may remain as a coating to lubricate the run flat tyre, or may be broken down e.g. by shear, shear and temperature, a reagent, or a reagent in combination with shear and temperature (in the latter case the reagent will be included in the composition). The liquid lubricant includes a poly (oxyalkylene) glycol to which may be added one or more of alcohols e.g. ethyl alcohols, water, glycol ethers, soaps, alkalis, and polymers containing functional groups. The lubricant may be gelled by a finely divided gelling agent and the composition may be mechanically strengthened by the addition e.g. when the gelling agent is silica, of sodium stearate, sodium carbonate or hexamethylene diamine. The gelling agent may comprise silicates (e.g. clays, micas, asbestos) in the form of platelets, rods, fibres or spherical particles, silica, polar organic polymers (e.g. cellulose or nylon), crystalline polymers, or, when the lubricant includes a polymer containing functional groups, isocyanate, or metal oxides (e.g. magnesium oxide, zinc oxide or aluminium oxide). Reagents may include-for hydrogen-bonded gels-water, alcohols, acids, aprotic solvents (e.g. dimethyl formamide, dimethyl sulphoxide, tetra-hydrofuran) or certain aqueous inorganic salt solutions for ionic bonds-solvents of low dielectric constant; for gels using metal oxidesproton donors; for gels with weak chemical bonds (e.g. allophanates in polyurethane systems)-phenols. In examples disclosed a composition was prepared from poly (oxyalkylene) glycol-25g, silica-1.25g, with or without sodium carbonate- 0.25g. In a further example a composition was prepared from poly (oxyalkylene) glycol-25g, water-5g, alcohol-2.5g, silica-1.63g and sodium carbonate-0.33g. A suitable reagent for the above examples is hydrochloric acid in an amount 50% by volume of the volume of the gel. In another example poly (oxyalkylene) glycol-50g containing hydroxyl end groups was treated with a mixture of 2:4 and 2:6 tolylene diisocyanates (TD1) using cobalt naphthenate as catalyst, and the mixture was heated at 115‹C for 30 mins. TD1 in quantities of 3.3g, 2.2g and 1.6g gave, respectively, stiff, medium and soft gels. Other examples are disclosed which include poly (oxyalkylene) glycol, 5% (by weight) of silica, 11% (by weight) of water and sodium carbonate (in varying quantities), bicarbonate of soda, and borax. Also disclosed is a composition including poly (oxyalkylene) glycol and finely divided silica in an amount of 10g/100g of gel. [GB1444347A]
