Definitions

  • the present invention relates to a high dropping-point lithium-complex grease composition having improved extreme pressure properties.
  • lithium-complex grease compositions which contain (a) as gelling component e.g. a lithium soap of a C 12 to C 24 hydroxy fatty acid and (b) as a complexing metal salt e.g. a lithium salt of a boric acid.
  • gelling component e.g. a lithium soap of a C 12 to C 24 hydroxy fatty acid
  • complexing metal salt e.g. a lithium salt of a boric acid
  • the present grease compositions may also contain such anti-noise additives
  • the purpose of the present invention is to render extreme pressure properties to high dropping-point lithium-complex grease compositions of the above type.
  • This invention therefore relates to a high dropping-point lithium-complex grease composition having improved extreme pressure properties, comprising a lubricating oil and the following components:
  • Any conventional lubricating oil can be used. While a typical one is a mineral oil, use can also be made, singly or in combination with the mineral oil, of a synthetic oil including ester oils, such as a diester oil, e.g. dioctyl azelate, and a tetraester oil, e.g.
  • the pentaerythritol ester of an aliphatic monocarboxylic acid or poly-alpha-olefin oligcmers, such as octene-1/decene-1 copolymers, having a viscosity of 41.0 cSt at 37.8°C, a viscosity index (V.I.) of 130 and a flash point of 223°C.
  • the lubricating oil may have a viscosity ranging from about 2 to 500 cSt, preferably from 20 to 200 cSt, at 40°C.
  • the C 12 to C 24 hydroxy fatty acids include saturated or unsaturated monocarboxylic fatty acids containing a hydroxyl radical, especially those acids containing 18 carbon atoms and a hydroxyl radical in the 9-, 10- or 12-position, such as 12-hydroxy stearic acid and ricinolic acid.
  • the lithium salts of the above fatty acids and hydroxy fatty acids can be singly used or combinedly with one or more of others.
  • said carboxylic acids can be reacted with lithium hydroxide not only in the form of free acids but also as glycerides.
  • Suitable salts are lithium metaborate, lithium diborate, lithium tetraborate, lithium pentaborate, lithium perborate and lithium ortho borate, such as the monolithium salt of ortho boric acid (H 3 BO 3 ).
  • Suitable salts are potassium, sodium, alkaline earth metal (e.g. Ca, Ba or Mg) and zinc metaborate, diborate, tetraborate, pentaborate, perborate and ortho borate. Partial as well as full salts are suitable.
  • the grease composition according to the present invention can be prepared by uniformly admixing and finely dispersing the three components (a), (b) and (c) in the base oil mentioned above. While the amounts of these three components compounded in the base oil above are not necessarily critical but can be variable for individual components, it is generally advantageous to use them in the following proportions per 100 weight parts (pbw) of the base oil;
  • Component (a)/Component (b) mol ratio 0.5 to 10, especially 1 to 5.
  • the present grease composition can also be prepared as follows.
  • the base oil is admixed with a hydroxy fatty acid for forming a component (a), followed by an e.g., equivalent, amount of LiOH to form a soap.
  • a boric acid for a component (b) is admixed, followed successively by an, e.g equivalent, amount of LiOH, another portion of a boric acid and an e.g., equivalent, amount of a metal compound of a metal of component (c), e.g. an oxide or hydroxide of K, Na, an alkaline earth metal or Zn.
  • the total of the two portions above of boric acid may be admixed simultaneously in the first mixture, followed by LiOH and said metal compound.
  • lubricant-additives such as neutral or basic metallic detergents, such as basic Ca salicylate, or ashless dispersants, rust inhibitors (e.g., paraffin oxide, amino imidazoline or barium dinonylnaphthalene-sulphonate), oxidation inhibitors (e.g. 2,6-ditertiary butyl-4-methylphenol), N-phenyl-a-naphthylamine or diphenylamine octylate) and conventional extreme-pressure additives (e.g. zinc naphthenate or other zinc compounds such as zinc dithiophosphates or zinc-oxide, lead naphthenate, sulphurized oils and fats, or tricresyl phosphate), in the proportions ordinarily employed.
  • neutral or basic metallic detergents such as basic Ca salicylate, or ashless dispersants
  • rust inhibitors e.g., paraffin oxide, amino imidazoline or barium dinonylnaphthalen
  • the present grease compositions can be used, for example, for the lubrication of the bearings of electric motors as well as of the wheel bearings in automotive bearing/axle integrated structures.
  • Component (a) was lithium 12-hydroxy stearate, component (b) lithium borate and component (c) potassium borate.
  • This grease was prepared in situ by mixing and heating 9.00 %w of 12-hydroxy stearic acid, 2.96 %w boric acid, 2.33 %w lithium hydroxide, 0.45 %w potassium hydroxide and 85.26 %w mineral lubricating oil.
