Description
Technical Field
The invention relates to a dry film lubricant and a preparation method thereof, in particular to a high-load-resistance molybdenum disulfide dry film lubricant for a bushing and a preparation method thereof, and belongs to the field of preparation of dry film lubricants.
Background
In recent years, with the rapid development of aerospace industry, the requirement on the fatigue resistance manufacturing technology of the airplane is continuously increased, and the cold extrusion hole reinforcing technology of the bush is one of the most important methods, is widely applied to reinforcing work of airplane fastening holes, and has an obvious reinforcing effect on the fastening hole structure. In the process for strengthening the cold extrusion hole of the bushing, which is mainly characterized by processing at normal temperature, the lubrication of the inner wall of the bushing is a very critical process link besides the smooth hole making.
The cold extrusion hole strengthening process of the bushing has high extrusion amount and large extrusion force, and can cause (1) the sliding and bonding phenomenon between the bushing and the core rod during extrusion to cause the bushing to axially move in the hole and scratch the inner wall of the hole if the lubrication is improper; (2) the lining is easily wrinkled or the core rod is easily broken. Therefore, the lining inner wall applies high-load-resistant lubricant in a correct mode, and the method is an effective way for solving the problems of scratching the inner wall and breaking of the core rod in the cold extrusion hole strengthening process. Research has shown that a lubricant suitable for cold extrusion hole strengthening of a bushing should have several characteristics: 1. the paint has high bearing capacity, high toughness and high adhesive force; 2. the friction coefficient is low; 3. has no pollution.
As an important solid lubricant, the molybdenum disulfide dry film lubricant is particularly suitable for high-temperature and high-pressure conditions, is also suitable for mechanical working states with high temperature, high pressure, high rotating speed and large load, and can effectively prolong the service life of a friction pair. The molybdenum disulfide dry film lubricant has the same load bearing capacity as the substrate because the load is applied to the metal substrate by the dry film. Generally, its load-bearing capacity is greater than the yield limit of the substrate (aluminum alloy, titanium alloy, alloy steel). The lubrication of dry film lubricants is based on transfer lubrication. After a dry film is sprayed on the surface of one of the friction pairs, when a machine part moves, the solid lubricant on the surface of the dry film is transferred to a dual surface, a continuous film is formed along with continuous transfer to cover the whole friction surface, and the friction between the dry film and the transfer film occurs, so that the lubrication state is optimal, the friction coefficient is lowest, and the dry film lubrication state is the optimal state. In addition, the dry film lubricant has a low friction coefficient which is generally between 0.02 and 0.2, and has no corrosion and pollution to the machine body.
However, the currently used molybdenum disulfide dry film has the outstanding characteristic of being easily oxidized and failed in the atmosphere (particularly in the humid atmosphere). And as the machine member operates under the working condition of high bearing capacity, the dry film molybdenum disulfide is worn quickly, abrasive dust particles are hardened and dried due to heating and mechanical action, the dry film and the transfer film are scratched, the wear speed is accelerated, and finally lubrication failure is caused.
Disclosure of Invention

step 3, calcining the molybdenum disulfide, antimony oxide and tantalum powder at 690-790 ℃ for 25-35 minutes, cooling to 100-110 ℃, adding tributyl citrate emulsion, cooling to 80-90 ℃, adding the mixed solution of the inorganic nano modified novolac epoxy resin and the polyamide-imide resin in the step 2, and then carrying out ultrasonic dispersion grinding for 2-3 hours;

The phenolic epoxy resin is mixed in PAI in a certain proportion, and as the secondary amide active functional group of the PAI can react with the epoxy functional group, and meanwhile, the molecular chain contains a large number of benzene ring structures, the wear resistance and the thermal stability of the coating material can be effectively improved;
3) the phenolic epoxy resin and the polyamide-imide resin are subjected to composite inorganic nano modification and then serve as organic adhesives, so that the strength and toughness of a lubricating film layer are improved, Sb2O3 is used as a filler, Sb2O3 and molybdenum disulfide have a certain synergistic antifriction effect, the wear-resisting service life of the coating can be prolonged, Sb3O4 is generated from Sb2O3 at a high temperature, the oxidation of MoS2 can be prevented, the wear-resisting service life is prolonged by utilizing the self-consumption of the Sb3O4, and the friction coefficient is reduced;
4) the tantalum powder can be used as an oxidation inhibitor and a high-temperature-resistant filler, the high-temperature resistance and the corrosion resistance of the lubricating coating can be obviously improved by adding the tantalum powder in a certain proportion, and the rapid abrasion of the coating caused by friction heating in the extrusion strengthening process is prevented;
5) the tributyl citrate is an environment-friendly polymer material auxiliary agent, has no toxicity, good compatibility, high plasticizing efficiency and excellent cold resistance, light resistance and water resistance. The addition of such a substance to the lubricant may further enhance its toughness;
