Description
Technical field
The present invention relates to be used for guarantor's oil-treatment agent of precision meter such as clock and watch, that is, prevent the treatment agent of watch oil diffusion and use the clock and watch of this guarantor's oil-treatment agent.The base plate, wheel sheet and the gear that more specifically relate to clock and watch are protected guarantor's oil-treatment agent that oil treatment is used.
Technical background
Clock and watch include clockwork driven mechanical clock and the power-actuated electronic watch of battery are housed.No matter be mechanical clock or electronic watch, all have from the drive disk assembly of drive source transfer function power.Drive disk assembly is made of gear and wheel sheet etc.
In mechanical clock, since the bigger motivating force that part is continued, the metal part of therefore main use.And in electronic watch,,, bring into use plastics (engineering plastics etc.) part because of the bigger motivating force that part is not continued though also be to use metal part at present.
Usually, from using on the character, wish all that generally clock and watch can long term operation.For this reason, add clock and watch lubricating oil at rotatable parts, prevent the deterioration that frictional wear causes, the inhibition rotatable parts are deterioration with the increase of duration of service.
But, even add clock and watch lubricating oil, but, constantly vibrated because wrist-watch is worn on the wrist at rotatable parts, therefore exist clock and watch with lubricating oil easily from the effusive problem of rotatable parts.If lubricating oil flows out problem will take place, promptly can not prevent frictional wear, along with the increase of duration of service, the phenomenon that clock and watch stop walking finally takes place in the rotatable parts deterioration like this.
Therefore, with the increase deterioration of duration of service, must protect oil treatment, diffuse out from rotatable parts with lubricating oil to prevent clock and watch to the position of apply oil for preventing rotatable parts.
Usually, as preventing the method for lubricating oil from the position diffusion of apply oil, the known grease proofing treatment process that the use oil-proofing agent is arranged.Processing such as the useful fluorine based compound of this grease proofing treatment process have added the surface in addition, position (position that will keep lubricating oil) of lubricating oil, make this surface have grease proofness, thereby prevent the method (the Japanese Patent spy opens the 2001-288452 communique) of the diffusion (outflow) of lubricating oil.
But in this class precision meter of clock and watch, because each part is little, above-mentioned anti-oil treatment is difficult to carry out.Therefore, existing clock and watch with protect the oil treatment method be fluorine with high density be tensio-active agent (for example, 3M corporate system Off ロ ラ-De 722) is dissolved in a large amount of lower boiling fluorine series solvents, guarantor's oil-treatment agent of modulation lower concentration, the part that will have metal system or plastic rotatable parts again is immersed in this solution, and to make fluorine be tensio-active agent attached to the surface of part to keep lubricating oil.
But, this method is that utilization is that surface and the lubricated oil surface tension that tensio-active agent is handled keeps lubricating oil through fluorine, when not considering to rotate basically the rub resistance abradability of (lubricating oil is done the time spent) and and the interaction of lubricating oil, can not obtain to protect fully the oiliness energy.Also have, existing fluorine is a tensio-active agent owing to be to use fluorine series solvent as thinner modulation treatment liquid, therefore can not be with same solution-treated plastic material and metallic substance, and must modulation treatment solution suitable, correspondence.Also have, using this fluorine is tensio-active agent when carrying out surface treatment, exists the surface can the residual problem that spot shape vestige is arranged.
And fluorine series solvent unit price height and usage quantity are big, and like this with regard to problems economically such as the price that has treatment solution increase, and the heating that removes when desolvating can produce obnoxious flavour, and fluorine is that tensio-active agent such as is difficult to decompose at the problem on the environment.
As the method for this class problem of solution, the nickel composite deposite that utilizes that has proposed not need to prevent the oil diffusion carries out the scheme of solid lubrication (No. the 3269090th, Japanese Patent).But adopt this method to have the color blackening and the loaded down with trivial details problem of treatment process of part.
The purpose of this invention is to provide a kind of guarantor's oil-treatment agent, it has good guarantor's oiliness energy to precision meters such as clock and watch.Another purpose provides does not use guarantor's oil-treatment agent that can both use at metal workpieces and plastics workpieces of fluorine series solvent and the clock and watch that use this guarantor's oil-treatment agent.
