Problems solved by technology

Nano wear-resistant materials are nano-alumina or nano-silicon dioxide. The base material is treated by vacuum coating and sprayed to improve the adhesion and wear resistance of the coating film, but it is only used for the surface protection of electronic products. Has no lubricating effect and cannot be used as a dry film lubricant for metal parts

Embodiment 1

[0020] The preparation method of light-cured dry film lubricant is as follows: weigh a certain amount of epoxy resin, heat up to 60°C and start stirring, add a certain amount of hydroquinone at 75°C, and add a certain amount of N, N— The mixed solution of dimethylaniline and acrylic acid is stirred and refluxed at a constant temperature of 100°C for 5 hours to obtain a viscous oligomer. Weigh a certain amount of oligomer, dissolve it with a certain amount of reactive diluent, and then add a certain amount of photoinitiator and accelerator to obtain a bonding matrix. Add dispersants, wear-resistant additives, solid lubricants, antioxidants, and magnetic additives in sequence to the bonding matrix, and then undergo high-speed dispersion and sand grinding dispersion respectively, and then filter and package to obtain it. By weight in dry film lubricant film-forming substances: 33.20 parts of epoxy resin; 5.09 parts of acrylic acid; 0.39 part of N, N-dimethylaniline; 0.02 part of ...

[0022] The preparation method of light-cured dry film lubricant is as follows: weigh a certain amount of epoxy resin, heat up to 60°C and start stirring, add a certain amount of hydroquinone at 75°C, and add a certain amount of N, N— The mixed solution of dimethylaniline and acrylic acid is stirred and refluxed at a constant temperature of 110°C for 3 hours to obtain a viscous oligomer. Weigh a certain amount of oligomer, dissolve it with a certain amount of reactive diluent, and then add a certain amount of photoinitiator and accelerator to obtain a bonding matrix. Add dispersants, wear-resistant additives, solid lubricants, antioxidants, and magnetic additives in sequence to the bonding matrix, undergo high-speed dispersion and ball milling dispersion, and then filter and package to obtain it. In dry film lubricant film-forming material by weight: 33.20 parts of epoxy resins; 5.09 parts of acrylic acid; 0.39 parts of N, N-dimethylaniline; 0.02 parts of hydroquinone; 8.40 par...

Embodiment 3

[0024]The preparation method of light-cured dry film lubricant is as follows: weigh a certain amount of epoxy resin, heat up to 60°C and start stirring, add a certain amount of hydroquinone at 75°C, and add a certain amount of N, N— A mixed solution of dimethylaniline and acrylic acid was stirred and refluxed at a constant temperature of 90°C for 6 hours to obtain a viscous oligomer. Weigh a certain amount of oligomer, dissolve it with a certain amount of reactive diluent, and then add a certain amount of photoinitiator and accelerator to obtain a bonding matrix. Add dispersants, wear-resistant additives, solid lubricants, antioxidants, and magnetic additives in sequence to the bonding matrix, undergo high-speed dispersion and ball milling dispersion, and then filter and package to obtain it. By weight in dry film lubricant film-forming substances: 15.57 parts of epoxy resin; 2.42 parts of acrylic acid; 0.20 part of N, N-dimethylaniline; 0.01 part of hydroquinone; 7.20 parts o...

Abstract

The invention discloses a light cured dry film lubricant. The film forming substance of the light cured dry film lubricant consists, by weight percent, of 10 to 50% of solid lubricant, 0.2 to 5% of dispersant, 4 to 10% of antiwear additive, 2 to 6% of antioxidant, 0.5 to 2.5% of magnetic additive and 35-80% of coating film bonding matrix, wherein the bonding matrix consists of oligomer, reactive diluent, photo-initiator and auxiliary. The dry film lubricant disclosed by the invention can be cured under ultraviolet light at normal temperature, and is fast in being cured, environment-friendly, excellent in antiwear property and small in frictional surface scratch. The light cured dry film lubricant is applicable for the lubricating antiwear coating on oil-free lubrication components, and especially applicable for the lubricating antiwear coating on the surface of non-temperature-resistant base materials.

Description

technical field [0001] The invention belongs to the technical field of dry film lubricant preparation, in particular to an environment-friendly dry film lubricant. Background technique [0002] Dry film lubricants are solid lubricants, wear-resistant additives, etc., which are firmly bonded to the friction surface where relative movement occurs by means of a binder, and play a protective role in wear-resistant lubrication. It can be sprayed, brushed, dipped, etc. The dry film lubricant is coated on the surface of the friction substrate, dried at a certain temperature and solidified to form a solid lubricating dry film. The UV-curable dry film lubricant can be cured into a film under the irradiation of ultraviolet light. The drying time is short and it can be cured at room temperature. The operation is simple, which makes the production efficiency high, the equipment cost is greatly reduced, and it is environmentally friendly. [0003] The UV-curable dry film lubricant adopt...
