Abstract

The invention relates to a rare-earth-containing anti-explosion functional composite coating which is capable of inhibiting or preventing generation of sparks and achieving the purpose that no spark is generated during collision after being coated. The rare-earth-containing anti-explosion functional composite coating consists of a mixture A and a mixture B, wherein the mixture A is prepared from the following components in percentage by mass: 60-80% of epoxy resin, 10-25% of tung oil, 7-27% of liquid rubber and 3-5% of a rare-earth oxide; the mixture B is prepared from the following components in percentage by mass: 0-60% of elastic functional packing, 10-30% of solid lubricant packing, 20-40% of low-temperature phase change thermal absorption packing and 10-30% of flame retardant type packing. The rare-earth containing anti-explosion functional composite coating has the functions of corrosion prevention and explosion prevention, and is not only used in coal mines, but also widely used in environments that explosion can be caused by generated sparks when metal parts in high-speed movement collide with one another, such as oil fields, oil depots, explosives and dust.

Description

technical field [0001] The invention relates to a rare earth-containing anti-explosion function composite coating, in particular to a kind of anti-explosion function composite coating not only limited to the underground use of coal mines, but also widely used in oil fields, oil depots, gunpowder, dust and other metal parts that need to prevent high-speed motion from colliding with each other to generate sparks and cause Explosion-proof functional composite coatings in explosive environments. Background technique [0002] The support material for underground coal mining operations in coal mines has been changed from wood to steel body hydraulic props. However, for coal seams with a thickness of more than 3.5 meters, steel body hydraulic props are too heavy to move underground, and they have to be mined in layers, which is expensive. Therefore, aluminum alloy hydraulic props have been developed at home and abroad, (under the same height, the aluminum alloy props are less than...
