Problems solved by technology

[0004] However, the existing lubricating oil additives have many deficiencies in reducing the friction coefficient and repairing the worn surface, such as the thickness of the formed protective layer is not enough, because the wear of many large mechanical structures that need to be repaired is relatively large, sometimes reaching more than 10 microns, However, most of the current lubricants can only form a few microns of wear-resistant protective layer on the metal surface, which cannot effectively eliminate the wear phenomenon, restore the factory precision of the mechanical structure, and realize the effect of remanufacturing the wear structure precision.
At the same time, when the current lubricant is used, it has the problem of slow reaction speed and a long running-in repair time to form an effective wear-resistant protective layer, which makes the repair cost high due to equipment shutdown.
In addition, the protective layer formed by the current lubricant still has defects such as hardness, poor finish, and poor repair effect. Based on the above shortcomings, the existing lubricating oil additives have insufficient repair, energy saving, and cost-saving effects during use. Therefore, it is urgent to develop a new material with short running-in repair time and high repair accuracy.

Embodiment 1

[0019] Example 1. Preparation of intelligent remanufacturing material 135KG for the surface precision of metal friction pairs:

[0020] Weigh raw materials according to the following proportions: magnesia 35KG, magnesite 25KG, aphaphatic graphite 20KG, boron nitride 10KG, polyethylene glycol phosphate 9KG, iron oxide 0.5KG, mixture of zirconia and titanium dioxide 0.3KG , of which zirconium dioxide 0.1KG, titanium dioxide 0.2kg, polyoxyethylene sorbitan 0.2KG.

[0021] The above-mentioned substances and lubricating oil are mixed in a ratio of 2:1, and the mixture is put into a grinder to grind for 4 hours to obtain a mixed solution of ultrafine particles (with a particle size of 0.1-1 μm). Then cool and settle for 10 hours, and filter to obtain the finished product of smart remanufacturing material with the surface precision of the metal friction pair.

Embodiment 2

[0022] Example 2. Intelligent remanufacturing material of metal friction pair surface precision 140KG:

[0023] Weigh the raw materials according to the following proportions: magnesia 30KG, magnesite 22KG, aphaphatic graphite 25KG, boron nitride 12KG, polyethylene glycol phosphate 10KG, iron oxide 0.2KG, mixture of zirconia and titanium dioxide 0.6 KG, including zirconium dioxide 0.2KG, titanium dioxide 0.4kg polyoxyethylene sorbitan ether 0.2KG.

[0024] Mix the above-mentioned substances with mineral oil at a ratio of 1:1, put them into a grinder and grind for 6 hours to obtain a mixed solution of ultrafine particles (with a particle size of 0.1-1 μm). Then it was cooled and precipitated for 8 hours, and the finished product of the intelligent remanufacturing material with the surface precision of the metal friction pair was obtained through filtration.

Embodiment 3

[0025]Embodiment 3. According to Embodiment 1, the use method and effect of the intelligent remanufacturing material of the surface precision of the metal friction pair:

[0026] In the process of adding this product, you only need to mix and dilute 20 times the weight of lubricating oil with the surface precision intelligent remanufacturing material of the metal friction pair, and then inject it from the oil port of the machine (it is best to add it before starting the machine). Or directly add the intelligent remanufacturing material of the surface precision of the metal friction pair to the lubricating oil of the mechanical equipment, and ensure that the weight ratio of the material to the lubricating oil is 1:20. Then turn on the device and work for 10-20 minutes, then stop it for 5 minutes, and then it can be used normally.

[0027] The product has been tested and found that when it is used as an automobile engine oil additive, the cylinder pressure of the automobile will...

Abstract

The invention relates to an intelligent remanufacturing material for metal friction pair precision, which can be widely applied as an additive to a lubricant for metal devices with friction loss and can effectively reduce the friction coefficient and restore the precision. The material is prepared by the following steps of: firstly, mixing the following raw materials in parts by weight: 25-40 of magnesium oxide, 20-30 of magnesite, 15-25 of aphanitic graphite, 10-15 of boron nitride, 5-10 of poly(ethylene phosphate), 0.1-1.0 of iron oxide, 0.1-1.0 of mixture of titanium dioxide and zirconium dioxide and 0.1-1.0 of surfactant; and then mixing and grinding the mixture with a lubricant, then precipitating and filtering.

Description

technical field [0001] The invention relates to an intelligent remanufacturing material of the surface precision of a metal friction pair. Background technique [0002] Saving energy and improving the efficiency and lifespan of mechanical equipment is one of the goals pursued by our country's national policies and enterprises. At present, there are two main technical approaches to solve the problem of metal wear and failure in mechanical equipment: one is anti-wear technology, that is, to choose suitable wear-resistant materials to manufacture friction pairs, and reduce the wear of parts (parts); the other is repair technology, namely A variety of technical means are used to repair the worn metal parts, so that the size of the parts can be restored to the state before the wear. Traditional repair methods include coating, repair welding or inlay technology, but there are problems of high cost, poor precision, and poor repair effect, especially difficult to repair mechanical ...
