Definitions

  • the invention relates to a process for the preparation of oil-in-water emulsions containing liquid alcohols and their use as release agents for hydraulic binders.
  • DE-A-38 19 193 discloses liquid oil-in-water emulsions of polar oil components which have been produced at a temperature in the range of the phase inversion temperature interval or above and are therefore low viscosity, finely divided and very stable.
  • emulsifiers and co-emulsifiers such emulsions are so finely divided that their particles are no longer visually visible.
  • Such emulsions, which have a transparent, bluish opalescent appearance, are also referred to as microemulsions.
  • fatty alcohols as mold release agents for hydraulic binders.
  • GB 1 294 038 describes mold release agents based on aliphatic, saturated or unsaturated alcohols and a cationic emulsifier.
  • EP-A 561 465 proposes emulsifiable mold release agents for hydraulic binders based on fatty acid esters of polyols which do not carry any HI atoms in the ⁇ position to the OH group. Higher aliphatic monofunctional alcohols can also be added to the esters.
  • the emulsions are prepared by emulsifying the mold release agents in water with stirrers.
  • This method has several disadvantages; e.g. problems with emulsion stability occur.
  • the viscosity of the emulsions can increase during storage, for example, or the oil component can be separated by creaming.
  • Some of these disadvantages can be avoided by using special emulsifying units which make it possible to produce particularly fine-particle emulsions. However, the operation of such units is time-consuming and costly.
  • the object of the invention was to provide a process which avoids the disadvantages mentioned above and allows stable, liquid alcohols to be used as emulsions containing oil components To be available that can be used as mold release agents for hydraulic binders.
  • stability means that the emulsion neither creams nor thickens at least 1/2 year, better 1 year at room temperature. Temperature fluctuations occur during storage and transport of the emulsions, which likewise must not impair stability. It is therefore desirable that the emulsions are stable against short-term temperature fluctuations between 5 and 40 ° C, that is, neither cream nor thicken.
  • the invention relates to a process for the preparation of oil-in-water emulsions by using a mixture of
  • a co-emulsifier from the group of saturated fatty alcohols with 16-22 C atoms or the partial esters of polyols with 3-6 C atoms with saturated fatty acids with 14-22 C atoms and
  • Another object of the invention is the use of emulsions produced by the process according to the invention for the treatment of formwork material in concrete construction.
  • water-immiscible alcohols are understood to mean those whose solubility in water at 20 ° C. is below 5% by weight.
  • Liquid at temperatures of 5 to 15 ° C. means that the alcohols or mixtures of alcohols according to the invention are mobile, flowable liquids at these temperatures.
  • the unsaturated fatty alcohols used are known compounds which can be obtained by partial hydrogenation of fats or fatty acid methyl esters.
  • the fats and oils used as raw materials are not purely chemical compounds, but their fatty acids have a C chain distribution and can be in saturated, mono- or polyunsaturated form. Accordingly, the fatty alcohols produced from them also have a C chain distribution and can contain saturated, mono- or polyunsaturated species.
  • the unsaturated fatty alcohols can consist of 12 to 22, preferably 16 to 18, carbon atoms and iodine numbers in the range from 40 to 170, preferably from 70 to 100.
  • Fats are used as the raw material base and oils of vegetable and animal origin are used, for example palm kernel oil, coconut oil, tallow, rapeseed oil, soybean oil, palm oil and sunflower oil. It is particularly preferred to use an unsaturated fatty alcohol based on tallow, sunflower oil with an oil acidity> 80% by weight and / or rapeseed oil, which can also be used without distillation.
  • Guerbet alcohols can also be used. Guerbet alcohols can be obtained by the known alkali-catalyzed condensation of aliphatic alcohols at temperatures of around 200 ° C. Alcohols with 8 to 22 carbon atoms can be used in the condensation reaction. Linear alcohols with 8 to 14 carbon atoms are preferably used for the condensation, which leads to the Guerbet alcohols with 16 to 28 carbon atoms which are preferably used.
