Abstract
The invention relates to polishing liquid used for a gem ball with 10-grade surface finish and a preparation method. The polishing liquid consists of the following components in part by weight: 3 to 6 parts of nano-diamond, 240 to 300 parts of stearic acid, 320 to 480 parts of kerosene, and 1 to 1.2 parts of sodium hydroxide. The surface of a workpiece polished by using the polishing liquid of the invention has high surface finishment; an operation method is simple; technical requirements are low; and the polishing liquid is suitable for large-batch production. The polishing liquid prepared by adopting the method of the invention is permanent suspension without precipitate.
Description
Technical field
The invention belongs to the polishing fluid field, particularly a kind ofly be used for polishing fluid and the preparation method that surface finish is 10 grades a gem ball
Background technology
Utilize synthetic sapphire hardness high, wear-resistant, coefficient of linear expansion is little, the high and acid and alkali-resistance of ultimate compression strength, characteristics such as corrosion-resistant, and be higher than performance such as 85%, various balls that available sapphire is processed and blind hole ball in the transmitance of 3-5 μ wave band.Ball is used for aspects such as the under meter ball valve, optical-fibre communications of liquid that highly corrosive environments uses or gas.Jewel blind hole ball is used to do the insulation measurement head of measuring instrument, precision measuring instrument instrument.Because the sapphire Mohs' hardness reaches 9 grades; Crystal has anisotropy, and sapphire ball surface finish quality reaches optical grade, surface smoothness reaches nano level, and circularity reaches 10 grades (0.00127mm) becomes technical barrier; Wherein, to reach optical grade more difficult for ball surface finish quality.
Mohs' hardness is that 10 grades diadust is that the synthetic sapphire polishing provides material, and therefore, suitable polishing fluid has been filled a prescription into the key of polishing sapphire ball.
Diamond polishing liquid at present commonly used is formulated according to a certain percentage by diadust and vegetables oil or MO; The polishing fluid that this method is formulated; It is inhomogeneous that nano-diamond powder disperses, leave standstill the certain period after, bortz powder all can be deposited in the bottom; Union clumps together, and can not form homodisperse, stable polishing fluid.In polishing process, must constantly rock or stir polishing fluid, even so, can not form homodisperse suspension liquid.The formulated in this way polishing fluid ball that polishes a gem, ball surface capacity produces serious surface imperfection such as scratch, ball poor surface smoothness.And, because the nano-diamond powder dispersion is inhomogeneous, make abrasive material have concentration also inhomogeneous; Cause the ball size wayward, the circularity grade does not reach the G10 level, and working (machining) efficiency is unstable; Experience and technical requirements to the direct labor are high, can not realize problems such as batch machining.
Summary of the invention
The purpose of this invention is to provide a kind of polishing fluid and preparation method thereof that surface finish is 10 grades a gem ball that is used for.Adopt the workpiece surface surface smoothness of polishing fluid polishing of the present invention good, working method is simple, and technical requirements is low, is applicable to production in enormous quantities.Adopting the polishing fluid of the inventive method preparation is nonvolatil suspension liquid, can not produce deposition.
Technical scheme of the present invention is following:
Surface finish is 10 grades a gem ball polishing fluid, and by Nano diamond, Triple Pressed Stearic Acid, kerosene with form, each component is:
Nano diamond: 3-6 weight part;
Triple Pressed Stearic Acid: 240-300 weight part;
Kerosene: 320-480 weight part;
Sodium hydroxide: 1-1.2 weight part
Reagent of the present invention all adopts the commercially available prod, wherein,
Nano diamond is shaped as spherical, and purity is not less than 99%;
Triple Pressed Stearic Acid is an analytical pure, and purity is not less than 99%;
Kerosene need be used filter paper filtering, removes granule foreign wherein;
Sodium hydroxide is analytical pure, and purity is not less than 99%.
1 weight part according to the invention is gram or kilogram.
The preparation surface finish is the method for 10 grades gem ball polishing fluid, and following steps are arranged:
(1) takes by weighing 3-6 weight part nano-diamond powder;
(2) nano-diamond powder was toasted 120 minutes under 100 ℃ temperature, take out, cooling is 30 minutes in air;
(3) ground 30 minutes;
(4) nano-diamond powder after the grinding adds 40% of 320-480 weight part, and ultrasonic dispersing is 60 minutes in UW, obtains containing the Nano diamond powder liquid;
(5) Triple Pressed Stearic Acid of adding weight part as claimed in claim 1 in step (4) the gained liquid mixes;
(6) step is heated to for (5) 100 ℃ and boils, and cools off then 360 minutes, and it is agglomerating that it is solidified;
(7) 60% of the kerosene gross weight of remainder is joined solidify in the agglomerating object, dissolving stirs, and the pH value that uses sodium hydroxide to adjust solution is 9.5-11, promptly obtains polishing fluid.
Select agate mortar for use when grinding in the said step (3), get nano-diamond powder≤2 weight parts at every turn, milling time≤30 minute.
Nano diamond evenly, stably is dispersed in the polishing fluid in the polishing fluid according to the invention, obtains nonvolatil suspension liquid; Triple Pressed Stearic Acid plays stablizer, dispersion agent and lubricant; Kerosene is a kind of oiliness diluent; Sodium hydroxide is the pH value regulator and helps the throwing agent.
Polishing fluid according to the invention is used for the processing of high-grade sapphire ball.
Table 1
Table 1 is that the polishing fluid of routine and the performance of polishing fluid according to the invention compare:
Polishing fluid of the present invention is used to process high-grade sapphire ball, and it shows quality and surface smoothness height, and is less demanding to operator's experience and state of the art, can enhance productivity greatly, reduces cost, and is applicable to batch machining.
