A kind of polyester resin solid lubricating block and preparation method thereof

Abstract

The invention discloses a polyester resin solid lubrication block and a preparation method thereof, and belongs to the field of solid lubrication materials. The polyester resin solid lubrication block is prepared from the following components in parts by weight: 30-45 parts of unsaturated polyester resin, 25-35 parts of modified hollow glass beads, 8-20 parts of emulsified oil, 5-15 parts of lubrication-assisting packing, 3-7 parts of an accelerant, 4-10 parts of a curing agent, 2-5 parts of methylsilicone oil and 2-4 parts of a reactive diluent. The prepared lubrication block has good hardness and an extremely low friction coefficient, and can be widely applied to a heavy-load sliding or rolling friction pair; distillated residue oil obtained from stearic acid is prepared by employing palm oil hydrolysis, comprehensive utilization of resources is achieved, lubricating grease does not need to be added, the polyester resin solid lubrication block has excellent self-lubricating property, and is beneficial to environment protection and iron and steel resource conservation, and a high polymer material is light and beneficial to reduction of mechanical loads.

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...

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

[0008] 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 excellent self-lubricating effects in the case of oil-free lubrication, which can effectively It solves the problem of solidification of lubricating oil in severe cold climates, the decrease of lubricating performance and damage to the equipment itself, and the problem of damage to the equipment caused by dust particles entering the slide rails for grinding when operating in high temperature and high dust environments in summer

The disadvantage is that the lubricating block is relatively unstable in size and is easily affected by water vapor

The disadvantage of the two is that the solid lubricating block is prepared under high temperature conditions, and the molding process is relatively complicated
