Abstract
The invention discloses a novel self-repairing nanomaterial for mechanical equipment. The novel self-repairing nanomaterial is characterized by comprising the following materials in parts by weight: 15 to 20 parts of polyphenol, 45 to 72 parts of cryolite, 10 to 17 parts of metallic silver, 11.5 to 23 parts of calcium carbonate, 10 to 13 parts of carbon black, 25 to 46 parts of ferric oxide, 5 to 17 parts of aluminum, 25 to 31 parts of nano silver, 22 to 40 parts of low density polyethylene, 5 to 11 parts of chloroprene rubber, 1 to 7 parts of Gul glue, 11 to 20 parts of chitin, 15 to 26 parts of ethylene-acrylic acid copolymer and 5 to 9 parts of molybdenum. The prepared self-repairing nanomaterial with stable dispersity is adopted, so that the mechanical equipment can be repaired in a manner that the equipment does not need to be disassembled in running. Thus, the traditional guarantee mode of the existing mechanical equipment of'taking the repairing as a main means and replacing a guarantee with the repairing' is changed, and a mode of'carrying out maintenance in equipment running and repairing without equipment disassembling' is truly realized. As a result, the novel self-repairing nanomaterial is of a breakthrough in the repairing filed of the mechanical equipment.
Description
Technical field
The present invention relates to a kind of mechanical means novel nano self-repair material.
Background technology
Friction wear is the ubiquitous phenomenon of nature, and the 1/3 above energy that the whole world energy produces is used for overcoming frictional resistance.Wearing and tearing are one of three kinds of principal modes of mechanical material inefficacy.Develop rapidly along with nanotechnology, the novel nano-material occurring in recent years, have and the bright right different characteristic of body phase material, can play friction-reducing and antiwear action to be different from the mode of action of conventional lubrication oil additive, simultaneously due to the little easier engaging friction of nano particles surface, can carry out filling up and repairing to a certain degree to friction surface, play self-repair function, therefore developing into of micro Nano material realized the operating not breakdown maintenance of mechanical means possibility is provided, in mechanical means, have broad application prospects, caused the extensive concern of various countries.
Self-repair material is by lubricant medium, as carrier, to enter into the surface of friction pair of metal, by the effect of frictional energy, at surfaces of metallic rubbing pairs, forms a kind of metalloid ceramic layer.Because nano material is in preparation and use procedure, the surfactivity of ultra-fine grain, along with particle diameter reduces and increases, is very easily reunited, and easily produce precipitation, thereby the result of use of material is reviewed one's lessons by oneself in impact greatly in lubricant medium.Existing technical scheme, most tensio-active agent or coupling agents of adopting are done powder surface modification, and effect is unsatisfactory.In addition, when current self-repair material is used for ferrous metals surface of friction pair, there is good repairing effect, and to many common ferrous alloy materials, or through the metallic rubbing pairs of surface treatment (as: plating), cannot form repair layer on its surface.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mechanical means novel nano self-repair material.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A mechanical means novel nano self-repair material, is characterized in that, comprises the material of following parts by weight: polyphenol 15-20 part, sodium aluminum fluoride 45-72 part, argent 10-17 part, calcium carbonate 11.5-23 part, the black 10-13 part of C, ferric oxide 25-46 part, aluminium 5-17 part, nanometer silver 25-31 part, Low Density Polyethylene 22-40 part, chloroprene rubber 5-11 part, guar gum 1-7 part, chitin 11-20 part, ethylene-acrylic acid copolymer 15-26 part, molybdenum 5-9 part.
The invention has the beneficial effects as follows: the present invention is the nanometer self-repair material with stable dispersion characteristic by being prepared into, realize the reparation of not disintegrating that mechanical means is in operation, changed traditional Support Mode that existing machinery equipment " be take and repaiied as master, with Xiu Daibao ", having realized " maintenance in service, the reparation of not disintegrating " truly, is machinery maintenance field new breakthrough.
