Problems solved by technology

But simply adding lube won't fix wear on metal surfaces
[0003] The repair effect advertised by some existing lubricating oil additives is just a kind of coating and "nanometer fluid lubrication" technology, which has a certain physical anti-friction effect on the surface of metal friction parts, but it does not have chemical properties, and there are still The following disadvantages: first, the coefficient of linear expansion is different from that of the matrix, and it is easy to fall off and peel off, and deposits will occur, causing the oil passage of the lubricating oil to become thinner, oil supply is not smooth or blocked; second, the addition amount is higher than 1%, It has an impact on the test index of lubricating oil; third, it must be re-added every time the lubricating oil is changed, and the service life is short; fourth, the wear and tear that has occurred cannot be repaired

Abstract

The invention provides a preparation method of a metal surface energy-saving material. The preparation method comprises the following steps that (a) diatomite and ash-calcium powder are put in hot water of 100-150 DEG C for rinsing, organic impurities are removed, then drying is performed after rinsing with clear water, and mixed powder I of the diatomite and ash-calcium powder is obtained; (b) boron nitride, a water repellent and kerosene are added into the mixed powder I and are evenly stirred to obtain mixed powder II; (c) the mixed powder II is put in a ball mill for grinding till third powder III with the particle size of 120-200 microns is obtained; (d) the third powder III obtained in the step (c) and ethyl alcohol are put in a stirrer, stirring is performed at the rotating speed of 1500-2000 r / min for 40-50 minutes to obtain a mixture IV; (e) basic oil is added into the mixture IV and is stirred for 2-3 hours. The preparation method is simple in process and low in cost, does not include complicated operating steps, has no higher requirement for manufactured devices and is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of metal manufacturing, and in particular relates to a method for preparing an energy-saving material on a metal surface. Background technique [0002] Mechanical equipment needs to use lubricating oil or grease to lubricate the parts to reduce the friction between them and prolong the service life of the equipment. But simply adding lube won't fix the wear on metal surfaces. [0003] The repair effect advertised by some existing lubricating oil additives is just a kind of coating and "nanometer fluid lubrication" technology, which has a certain physical anti-friction effect on the surface of metal friction parts, but it does not have chemical properties, and there are still The following disadvantages: first, the coefficient of linear expansion is different from that of the matrix, and it is easy to fall off and peel off, and deposits will occur, causing the oil passage of the lubricating oil to become thi...
