Definitions

  • Brake fluids with a preservative effect containing oleic acid Brake fluids with a preservative effect containing oleic acid.
  • the invention relates to brake fluids based on polyglycol ethers and polyglycols containing fatty acids.
  • DOT-3 brake fluids generally have good corrosion protection against tinplate, steel, cast iron, brass, copper and aluminum. Corrosion protection is only guaranteed if the metals are completely immersed in the liquid or otherwise well wetted by it.
  • a major disadvantage of this brake pastes is that they greatly increase in re-filling of the brake system with brake fluid, the viscosity, so that the viscosity of the filled fluid under circumstances, the maximum viscosities of 1,500.10- 3 m 2 / s at -40 ° C substantially exceeds. Such mixtures then no longer meet the requirements of FMVSS 116, DOT3.
  • Brake fluids containing corrosion-inhibiting oleic acid based on polyglycol ethers and polyglycols are already known from British patent specification 1,081,294.
  • di- or trialkylene glycols should be used according to the teaching of the patent mentioned.
  • these brake fluids provide insufficient rust protection in moisture corrosion tests compared to the brake fluids of the invention.
  • a brake fluid consisting of a) 20% by weight polypropylene glycol with an average molecular weight of 2000; b) an alkenyl dicarboxylic acid anhydride; c) 78.2% by weight of a commercial, technical polyglycol ether mixture and d) antioxidants were available to the public prior to the priority date of the present patent.
  • the task was therefore to propose brake fluids that can be used for impregnation at the same time and that allow the components to be stored for longer periods without corrosion.
  • the high molecular weight polyalkylene glycols are carrier substances that have low water solubility and are characterized by high lipophilicity. This allows them to dissolve the oleic acid more, so that the concentration of oleic acid in the brake fluid can be up to 3%.
  • Polyalkylene glycols of the formula I contained therein can consist solely of polypropylene glycols or can be prepared by mixing predominantly polypropylene glycols with polyethylene glycols or by reacting mixtures of ethylene oxide and (in excess) propylene oxide, statistical mixtures of compounds being formed which on average contain more propylene oxide than ethylene oxide residues and have molecular weights in the specified range.
  • polyethylene glycols can also be reacted with propylene oxide or polypropylene glycols with ethylene oxide, the starting polyglycols the amount of alkylene oxides and the polymerization conditions being chosen so that polyalkylene glycols according to the formula with the molecular weights specified there of 500 to 3000, preferably 1800 to 2200, are formed.
  • the procedure is expediently such that an epoxy mixture consisting of the desired molar ratios of ethylene oxide and propylene oxide is polymerized by methods known per se.
  • Oleic acid is used as corrosion inhibitor.
  • the basic components are the polyglycol ethers of the formula 11 which are customary in brake fluids, for example
  • the brake fluids according to the invention can also contain boric acid esters of glycol ethers of the formula 11, e.g. in amounts of 20 to 50% by weight.
  • Suitable boric acid esters are e.g. Methyl-tri-glycol-ortho-bora, ethyl-tri-glycol-ortho-borate, methyl / ethyl-di / tri-ortho-borate.
  • cast iron wheel brake cylinders are halved on the long side, cleaned with isopropanol and dried well.
  • the halved brake cylinder is then immersed in the brake fluid for 5 seconds each, drained for 5 seconds and stored in a closed container over a water vapor-saturated atmosphere.
