preparation example Construction

[0051] The preparation method of the above-mentioned metal wear repairing agent comprises the following steps:

[0052] S01: Grinding hydroxysilicate ore, apatite, vermiculite, aluminum chloride, and chrysotile into particles with a diameter less than or equal to 0.05mm;

[0053] S02: Dry the above pulverized particles with a vacuum dryer at 120° for 3 hours to remove moisture and crystal water;

[0054] S03: After adding lanthanum oxide and ferrous oxide powder, grind again for 24 hours until a powdery mixture is obtained.

[0055]In order to improve the homogeneity of the repairing agent, as an improvement of the technical solution, before the pulverized particles are dried in the step S02, the unground large particles can be removed by flotation. Before adding lanthanum oxide and ferrous oxide powder in the step S03, the large iron particles present in the dried particles can be removed by magnetic separation, and of course the above two steps can also exist at the same ti...

Abstract

The invention provides a metal wear repairing agent and a preparation method thereof as well as lubricating oil. The metal wear repairing agent comprises the following components in part by weight: 2-6 parts of hydroxyl silicate ore, 0.3-0.7 part of apatite, 4.5-5.5 parts of vermiculite, 0.2-0.7 part of aluminum chloride, 0.2-1 part of chrysotile, 0.02-0.07 g of lanthanum oxide and 0.05-0.15 part of ferrous oxide; the preparation method of the metal wear repairing agent comprises the following steps: 1) pulverizing a mixture I of hydroxyl silicate ore, apatite, vermiculite, aluminum chloride, chrysotile into particles having a diameter smaller than or equal to 0.05 mm; 2) drying the pulverized particles, removing moisture and crystal water; 3) S03: adding lanthanum oxide and ferrous oxide powder to obtain a mixture II, grinding the mixture II again until a powdered mixture is obtained. According to the invention, the metal wear repairing agent can repair damaged surfaces, reduce the friction, and improve the abrasion resistance.

Description

technical field [0001] The invention relates to the field of chemical industry, and in particular provides a metal wear repairing agent, a preparation method thereof and lubricating oil. Background technique [0002] Friction and wear are one of the main reasons for material failure. Generally speaking, wear refers to the reduction of the geometric size (volume) of parts, and the loss of the functions specified by the original design of parts is called failure. Among them, failure includes three types: complete loss of original function, reduced function, serious damage or hidden danger, continued use will lose reliability and safety. [0003] Since friction and wear are carried out on solid surfaces that are in contact with each other and relatively moving, the surface of the contact body and its properties are very important to the friction and wear performance. According to a large number of research results, the friction and wear properties of the material can be sign...
