Definitions

  • the present invention relates to a method for improving tyre traction and to a substance which when applied to the surface of the tyre improves its traction, particularly, but not exclusively, on snow.
  • a snow grip comprises a steel chain which passes around the tyre of the vehicle and, in use, has the effect of biting deeper into the snow layer to provide the necessary improvement in grip.
  • Various snow chains and snow grips are available which provide in varying degrees the improvement in grip which they are designed to produce.
  • the present invention solves the problem of grip in a different manner.
  • a method of improving the grip or traction of a vehicle tyre comprising applying an hydrocarbon based solvent to the surface of the tyre.
  • a vehicle tyre treated with an hydrocarbon based solvent there is provided a vehicle tyre treated with an hydrocarbon based solvent.
  • the application of the hydrocarbon based solvent to the surface of the tyre removes the grease and oil which may have come into contact with the surface of the tyre previously.
  • the improvement in traction of the tyre surface after application of the solvent produces a surprising improvement in traction on tyres already treated to remove any surface oil or grease, particularly on snow surfaces.
  • a solution containing an hydrocarbon based solvent for use in the method of the first aspect of the present invention.
  • the hydrocarbon based solvent is a white spirit or mineral spirit.
  • the white spirit is a petroleum hydrocarbon fraction with boiling point widths of the spirits covering 30 - 70 °C, most typically about 50°C in the range of boiling points from 100-300°C, most typically 140-250°C.
  • the hydrocarbon based solvent contains less than 25% aromatics, most preferably about 15%.
  • a method of driving a vehicle to improve friction comprising the steps of:- a) applying a hydrocarbon based solvent to one or more of the vehicle tyres and b) driving the vehicle over snow.
  • the hydrocarbon based solvent is at ambient temperature prior to application.
  • the method also improves if the tyres are at ambient temperature prior to application.
  • a tyre treated with a hydrocarbon based solvent for driving over snow.
  • an aerosol dispenser with a dispensing head displaced from the dispenser and connected thereto by an arm which extends beyond the body of the dispenser.
  • the displacement of the dispensing head away from the dispenser allows the head to be directed at the surface of the tyre underneath the wheelarch of the vehicle so that the jet can be applied directly to the surface of the tyre whilst the user grips the container without undue inconvenience and without having to apply the aerosol at difficult angles.
  • Figure 1 shows a schematic diagram of the dispensing head in use in accordance with the third aspect of the present invention.
  • Figure 2 shows an enlarged view of the dispensing head and stalk arrangement in accordance with the third aspect of the present invention.
  • a suitable hydrocarbon based solvent which can be used to put the invention into effect is BSS 254 which is a type of white spirit.
  • the manner in which this is produced is in accordance with techniques and methods which are known in the art.
  • the solvent has been tested on the tyres of vehicles after they had ground to a halt due to slippage on snow surfaces.
  • the effect of the application of the solvent to the tyre surface is to produce a surprising improvement in traction and, in all cases, resulted in the vehicle proceeding forward easily. This effect is illustrated by the following examples.
  • a typical passenger car tyre formulation was mixed and finalised in a laboratory scale Banbury mixer to produce about 1.27kg of compound.
  • the formulation is given below:
  • CBS 1.2 Rheometry was performed using a Monsanto MDR2000E to determine the optimum cure time at 160°C (please see included trace and table). Compound was moulded at 160°C for 17 minutes to form test sliders for the skid test.
  • Skid resistance of the compound was measured using a Pendulum Skid Tester by which the trailing edge of a slider (76.3 ⁇ 0.35mm) was dragged across different surfaces for a standard distance. The recovery of the pendulum on following through was a measure of the friction developed on any surface and a high skid number represents more friction or skid resistance. Each slider was cleaned with alcohol to remove any surface bloom or oil and the alcohol was allowed to evaporate before testing. There was a minimum of ten runs across each surface before an equilibrium skid number was measured.
  • Table 2 shows the results obtained from friction studies performed at ambient temperature under both dry and wet conditions.
  • the concrete surface is a non-abrasive one and so hardness is the most important property of the rubber that affects friction.
  • the wavy glass has a texture similar to a non-abrasive asphalt surface. ** After drying at ambient temperature the skid number recovered to within 1 unit of the original reading.
  • an aerosol can 2 has a removable head 4 which is fitted with a permanent extension stalk 6 which extends at right angles to the axis of the canister and is fitted with a spray head 8 at its other end.
  • the spray head 8 is permanently fixed to the extension stalk 6 but is rotatable thereabouts so that the angle can be varied to suit the position of the head with respect to the surface of the tyres.
  • the head 8 is fitted with a wide angle spray aperture 10 which gives maximum coverage of the tyre surface 12.
  • the method of applying is to pass the head 8 and stalk 6 beneath the wheel arch 14 of the vehicle so that the aperture 10 faces the surface onto which the aerosol is to be applied.
  • the user may then apply the aerosol without undue inconvenience and may twist the head of the aerosol in order to provide the most efficient spray pattern when applying the solvent to the tyre surface.
  • the aerosol canister 16 has a centrally disposed delivery tube 18 which allows the aerosol to pass upwards from the container into the head 20 which is fitted onto the upper part of the delivery tube 18 and has a co-operating L shaped delivery passage 22 which co-operates with the delivery tube 18 when the head is fitted thereon so that the aerosol may pass up through the delivery tube and into the L shaped tube 22 in the head.
  • the L shaped tube 22 exits the head 20 at the side thereof.
  • An extension stalk 24 fits into the same side of the fixed head to co-operate with the L shaped tube 22 so that the aerosol may pass down the extension stalk and into the dispensing head 26 where it passes through a second L shaped delivery passage 28 before delivery to the wide angle aperture 30.
  • the stalk extension is 300mm in length and is fixed permanently to nozzles 20 and 26.
  • the first nozzle 20 may, however, be removed from the canister delivery tube 18 and, if desired, an ordinary nozzle may be fitted thereon to use the aerosol canister in an ordinary manner. This may be used, for example, with vehicles which do not possess wheel arches.
