  A composition of organic hetero compounds as an antioxidant and antiwear additive for mineral lubricating oils

  摘要：

  As a multifunctional additive exhibiting antioxidant and antiwear activity for mineral lubricating oil, a composition of ammonium dialkyldithiophosphate (ADTP) with tetraalkyl thiuram disulfide (TDS) has been proposed, which provides lower sulfated ash, phosphorus, and sulfur contents compared with the traditional additive zinc dialkyldithiophosphate used for the same functions. Ammonium dialkyldithiophosphates bearing various alkyl radicals have been synthesized using structurally different amines. The antioxidant efficiency of ADTP samples has been shown by monitoring the formation and degradation of hydroperoxides in a hexadecane medium as a model of mineral oil. The tribological parameters of these compounds have been determined under boundary lubrication conditions.

  The present invention provides a method for producing a rubber composition containing a rubber component (A) of at least one selected from natural rubbers and synthetic dienic rubbers, an inorganic filler (B), a silane coupling agent (C) and an acidic compound (D), wherein the rubber composition is kneaded in multiple stages, and in the final stage of kneading, the acidic compound (D) is added, and the highest temperature of the rubber composition in the final stage of kneading is from 60 to 120°C. The production method enables production of a rubber composition having a low-heat-generation property while successfully preventing the coupling function activity of the silane coupling agent from lowering.

  The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.
