Embodiment 1

[0019] Example 1 Preparation of Metal Restoration Agent

[0020] The metal restoration agent prepared by the present invention can be formulated according to the following raw material components:

[0021] 5 parts of zinc dialkyldithiophosphate, 20 parts of calcium stearate, 3 parts of nano-magnesium oxide, 3 parts of nano-silicon dioxide, 1 part of polycarbon elastic resin, 2 parts of accelerator, 1 part of defoamer, amide 6 parts of base amine curing agent, 1.2 parts of ammonium sulfate, 7 parts of gull gum, 1.5 parts of nano-silver, 3 parts of polyphenol, and 7 parts of low-density polyethylene.

[0022] During specific preparation, the raw material components can also be:

[0023] 9 parts of zinc dialkyl dithiophosphate, 30 parts of calcium stearate, 8 parts of nano magnesium oxide, 8 parts of nano silicon dioxide, 5 parts of polycarbon elastic resin, 5 parts of accelerator, 3 parts of defoamer, amide 8 parts of base amine curing agent, 4 parts of ammonium sulfate, 11 pa...

Embodiment 2

[0027] Embodiment 2 Effect test of the metal restoration agent of the present invention

[0028] 1. Equipment life test

[0029] Taking the rolling bearing as the base, group B added the metal repair agent of the present invention to the lubricating liquid (with 500SN base oil for reconciliation, the addition amount is 8% of the total amount of lubricating liquid), group A is the comparative example (no metal repair agent) . The test results are shown in Table 1 below.

[0030] Table 1

[0031]

[0032] It can be seen from the data in Table 1 that one set of bearings failed when Group A operated for 127 hours, 140 hours, 270 hours, 275 hours, 301 hours, 323 hours and 370 hours, and only one set of bearings remained in normal operation at 390 hours ; However, after 400 hours of accumulative operation in Group B, no failed bearings occurred, and all eight sets of test bearings operated well. It is proved that the metal restoration agent of the present invention can prolon...

Abstract

The invention discloses a metal repairing agent. Amine curing agent, ammonium sulfate, gum gum, nano silver, polyphenol, low density polyethylene are prepared according to a certain weight. The metal repairing agent prepared by the invention has low production cost, good self-repairing effect and long maintenance time. After the metal repair agent is added to the lubrication system of the mechanical equipment, the lubricating oil (grease) is used as the carrier, and it is transported to the friction and wear surface of the metal parts in the state of no disintegration and non-stop. Under the action of friction energy, The repairing agent and the metal matrix have undergone the processes of ultra-fine grinding, special internal oxidation, deformation structure refinement and strengthening, etc., to form a super-hard and super-smooth nano-crystal protective layer, which automatically repairs friction and wear parts.

Description

technical field [0001] The invention relates to metal self-repair technology, in particular to a metal repair agent. Background technique [0002] With the development of industrial modernization, the requirements for the safe and continuous operation of various mechanical equipment are getting higher and higher, and the long-term operation of equipment under harsh environmental conditions such as high temperature, high pressure, impact, and corrosion often causes the entire part to be damaged due to local damage. Scrap, and eventually lead to equipment shutdown. Research has found that wear, corrosion and fatigue are the main three forms of mechanical material failure. Among them, the economic loss caused by wear and tear is very huge. It is estimated that the loss caused by friction and wear in my country can reach hundreds of billions of yuan every year. Therefore, energy saving and consumption reduction have always been the goal pursued by my country and the world in in...
