Abstract

The invention belongs to the technical field of preparation of lubricating agents for lubricating solid, and particularly relates to a quick-dry type dry film lubricating agent and a preparation method thereof. The quick-dry type dry film lubricating agent consists of the following raw materials in percentages by weight: 10-70% of a solid lubricating agent, 4-10% of a wear-resistant additive, 0.2-5% of a dispersing agent, 1-5% of an antioxidant, 0.5-2.5% of a solid additive, 10-50% of a tackifier and 5-20% of an anti-wear reagent at extreme pressure. The preparation method comprises the following steps: evenly mixing and stirring the various weighed components; carrying out ultrasonic oscillation on the components for 30-60 minutes in a stirring process; drying the components at the temperature of 80-100 DEG C until the weight percentage of water in the components is 20-30%; and grinding the dried components to obtain the lubricating agent. The film forming speed is high, the film forming time is about 15-30 seconds at normal temperature, and a film covers evenly.

Description

technical field [0001] The invention belongs to the technical field of lubricant preparation for solid lubrication, and in particular relates to a quick-drying dry film lubricant and a preparation method thereof. Background technique [0002] Traditional dry film lubricating oil is a lubricant containing solid lubricating particles of polytetrafluoroethylene (PTFE). The lubricant will be on the surface of the lubricated part (metal, paper, wood, rubber, plastic, glass, etc. Surface) volatilizes and forms a uniform lubricating film, and at the same time plays the role of waterproof, moisture-proof, anti-corrosion and cleaning. [0003] Traditional dry film lubricants are used to reduce friction and eliminate abnormal noise of metal, plastic and rubber sliding parts that require clean lubrication, such as slide rails, telescopic lenses, shafts, connectors, decks, antennas, springs, etc.; used in cameras , Audio-visual equipment (CD, DVD, video camera, car audio), office equip...
