Example Embodiment

[0024] Example one:

[0025] After degreasing, derusting and phosphating the 45 steel sample, spray the dry film lubricant of the following formula at a pressure of 0.20~0.35MPa and heat and cure at 180℃ for 45min to form a solid lubricating film of 10~15μm thick. The film adhesion is level 1, and it has passed the 50cm??kg impact test. After 48 hours of salt spray test at +35 ℃, 5% NaCl, there is no red rust on the working coating surface. The dry friction and wear test of the ring block was carried out using MM-200 under the conditions of a load of 100 N and a sliding speed of 0.419 m / s. The dry film lubricant film-forming substance is calculated as a percentage by weight: 62 parts of epoxy acrylic resin bonding matrix; 24 parts of solid lubricant; 0.4 parts of span-80; 4 parts of talc powder coated with epoxy; 3 parts of coated alumina; 5 parts of antimony trioxide; 1.6 parts of iron tetroxide. The solid lubricant is graphite, and when no magnetic particles are added, the we...

[0026] Embodiment two:

[0027] After degreasing, derusting and phosphating the 45 steel sample, spray the dry film lubricant of the following formula at a pressure of 0.20~0.35MPa and cure it at room temperature for 24 hours to form a solid lubricating film of 10~15μm thick. The focus is level 1. The working coating has no red rust after passing the 50cm~kg impact test, and after 48 hours of salt spray test at +35 ℃, 5% NaCl. The dry friction and wear test of the ring block was carried out using MM-200 under the conditions of a load of 100 N and a sliding speed of 0.419 m / s. The dry film lubricant film-forming substance is calculated as a percentage by weight: 62 parts epoxy phenolic resin bonding matrix; 24 parts solid lubricant; 0.4 parts span-80; 4 parts epoxy-coated titanium dioxide; epoxy-coated 4 parts of aluminum oxide; 4 parts of antimony trioxide; 1.6 parts of iron tetroxide. The solid lubricant is composed of graphite and molybdenum disulfide, and the mass ratio is 4...

[0028] Embodiment three:

[0029] After degreasing, derusting and phosphating the 40Cr steel sample, spray the dry film lubricant of the following formula at a pressure of 0.20~0.35MPa and heat and cure at 60℃ for 60min to form a solid lubricant film of 10~15μm thick. The film adhesion is level 1, and it has passed the 50cm??kg impact test. After 48 hours of salt spray test at +35 ℃, 5% NaCl, there is no red rust on the working coating surface. The dry friction and wear test of the ring block was carried out using MM-200 under the conditions of a load of 100 N and a sliding speed of 0.419 m / s. The dry film lubricant film-forming substance is calculated by weight percentage: 70 parts of epoxy silicone resin bonding matrix; 20 parts of solid lubricant; 0.2 parts of span-80; 4 parts of alumina coated with polyacrylate; Acrylate coated silicon carbide 3 parts; lead oxide 2 parts; nickel zinc copper ferrite 0.8 parts. The solid lubricant adopts tungsten disulfide, and when no magnet...

Abstract

The invention discloses a dry film lubricant used for metal parts, which comprises the following components in percentage by weight: 10-55% of soli lubricant, 4-10% of wear-resistant additive, 0.2-5% of dispersant, 2-6% of antioxidant, 0.5-2.5% of magnetic additive and 35-80% of adhesive base body. Compared with the prior art, the dry film lubricant has high wear-resistant performance and low scratch on friction surfaces. The dry film lubricant can be applied in the permanent lubrication of various mechanical metal parts, the initial running-in of pistons, cams, cylinders and like, the repairing of the parts of railway vehicles, aircrafts, ships and like, the fretting wear protection of steel rope shock absorber, mine elevator and bridge steel rope and the like.

Description

[0001] technical field [0002] The invention belongs to the technical field of lubricant preparation, in particular to a dry film lubricant used for metal parts and its application method. Background technique [0003] Dry film lubrication is a technique in which solid lubricants, wear-resistant additives, etc. are firmly bonded to the moving friction surface by means of a binder to play a protective role in wear-resistant lubrication. The material forming a solid lubricating dry film is called a dry film lubricant. The dry film formed by the dry film lubricant can act as a solid lubricant under dry friction conditions, and can also be used together with lubricating oil, grease, and paste, as well as an anti-corrosion protective film. It is also used for surface repair or surface wear that has been worn Anti-sticking and anti-fouling (dirt), etc. Widely used in friction parts of aviation, aerospace, machinery, transportation, petrochemical, construction, shipbuilding, ele...
