Problems solved by technology

The disadvantage is that the high temperature resistance is affected, and the release rate of the solid lubricating block will be accelerated under high temperature conditions
[0009] Patent CN201520403670.8 provides a self-lubricating block structure, which is characterized by the use of rare earth oil-containing nylon polymer materials, which increases self-lubricating properties, and also has self-lubricating effects in the case of oil-free lubrication, which can effectively solve severe cold weather The lubricating oil solidifies and the lubricating performance decreases, causing damage to the equipment itself. In summer, when working in a high-temperature, high-dust environment, dust particles enter the slide rails for grinding, causing damage to the equipment.
The disadvantage is that the lubricating block is relatively unstable in size and is easily affected by water vapor

Abstract

The invention discloses a phenolic epoxy resin solid lubricating block and a preparation method thereof and belongs to the field of solid lubricating materials. The phenolic epoxy resin solid lubricating block is prepared from, by weight, 30-40 parts of phenolic epoxy resin, 20-30 parts of modified hollow glass microbeads, 8-10 parts of emulsifying oil, 10-25 parts of lubricating-assistant filler, 3-8 parts of promoter, 10-20 parts of curing agent, 2-5 parts of methyl silicon oil and 3-6 parts of active diluent. The macromolecular oil-containing solid lubricating block prepared by the method has high hardness and extremely low friction coefficient and can be widely applied to heavy-load lubricating or rolling of a friction pair. The solid lubricating block has excellent self-lubricating performance, so that adding of lubricating grease is not needed, and environment protection and steel resource conservation are facilitated; a macromolecular material is light, so that reduction in load of machinery is facilitated.

Description

technical field [0001] The invention belongs to the field of solid lubricating materials, and in particular relates to a solid lubricating block and a preparation method thereof. Background technique [0002] In recent years, with the development of science and technology, higher and higher requirements have been put forward for the performance of various equipment and parts. Friction and wear is a common natural phenomenon. Statistics from the World Society of Tribology show that more than 1 / 3 of the world's primary energy is lost by friction, and the annual loss caused by wear and tear accounts for about 1% of the gross national product. In order to prolong the service life, save materials and energy, it is urgent to solve the problems of friction, wear and lubrication protection in many fields. [0003] There are four types of lubricating materials: gas lubricants, fluids (mainly oil), grease (semi-solid) and solid lubricating materials. Liquid and semi-solid lubricatio...
