Abstract:
The present invention relates to lubricant compositions and can be used for treatment of friction units in different machines and mechanisms in manufacturing processes, the purpose of which is modification of friction surfaces. The basis of the invention is the improvement of lubricant composition, in which as the consequence of the additional use of thickener and wax, the viscosity of lubricant composition sufficient for conversation of uniform distribution of solid component in lubricant composition in broad temperature range is provided; and at the expense of that, the possibility of conservation of lubricant composition in any packaging and bulks, which are usable even under operating conditions of machines and mechanisms, is reached. The lubricant composition acquires the state of gel, that is convenient to put on any friction surface, to deposit on a zone of friction of any friction units. The lubricant composition ensures the receiving of engineering results similar to those, which solid components exhibit using fine-dispersed powder on basis of natural minerals from flaky silicates series and at the same time the sedimentation properties of lubricant composition permit its continuous conservation in broad temperature range without variation of lubrication and modification properties.
