Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the present invention provides a kind of oil-water two-soluble diamond grinding paste and a preparation method thereof. The two-soluble diamond grinding paste is added with a water-soluble surfactant and an oil-soluble surfactant through compounding to solve the problem. At present, the oil film that appears when the oil-soluble diamond abrasive paste is processed on the surface of the mechanical valve leaflet is not easy to clean; at the same time, the two-soluble diamond abrasive paste reasonably selects the particle size and concentration of the diamond powder, thereby solving the problem of the diamond abrasive paste in the process of processing the mechanical valve leaflet. The surface quality does not meet the technical requirements and the polishing efficiency is low.

preparation example Construction

[0015] A preparation method of oil-water two-soluble diamond grinding paste, comprising the following steps:

[0016] (1) Accurately weigh each component according to the above weight percentage, among which the oil needs to be heated and melted and filtered with medical gauze before weighing;

[0017] (2) Add water-soluble surfactant and diamond micropowder to the dispersant, put it in an ultrasonic cleaning machine for ultrasonic dispersion for 15-30 minutes, stir until it is completely dispersed and evenly dispersed, and then take out the slurry;

[0018] (3) Mix the grease and oil-soluble surfactant evenly, then add it to the dispersed slurry, and mechanically stir to mix evenly;

[0019] (4) Cool and stir to normal temperature to obtain the oil-water two-soluble diamond grinding paste.

Embodiment 1

[0023] Take 3g of artificial diamond powder (M0 / 0.25), add 15g of ethylene glycol and 2g of triethanolamine monostearate and stir, and ultrasonically sonicate for 20 minutes to completely disperse and evenly obtain a slurry, and add 25g of melted and filtered palmitic acid and 5 g of sorbitol fatty acid ester to obtain a mixed slurry, which was placed in a cold water bath and stirred to room temperature to obtain an oil-water two-soluble diamond grinding paste.

[0024] The oil-water two-soluble diamond grinding paste prepared in this embodiment has good cleaning performance, high surface quality precision and about 2 times increase in work efficiency in terms of performance and processing requirements.

Embodiment 2

[0026] Take 4g of artificial diamond powder (M0.5 / 1.5), add 20g of glycerin and Pingjia-O2g, stir, place in ultrasonic for 15min, completely disperse and evenly obtain a slurry, and add 20g of cetyl palmitate that has been melted and filtered and 4 g of sorbitol fatty acid ester to obtain a mixed slurry, which was placed in a cold water bath and stirred to room temperature to obtain an oil-water two-soluble diamond grinding paste.

[0027] The oil-water two-soluble diamond abrasive paste prepared in this embodiment has good cleaning performance, high surface quality and about 3 times increase in work efficiency in terms of performance and processing requirements.

Abstract

The invention relates to an oil-water-soluble diamond grinding paste which is prepared from the following raw materials by weight percentage: 5 to 20% of diamond micro-powder, 25 to 50% of grease, 20 to 50% of a dispersing agent, 3 to 10% of a water-soluble surfactant and 3 to 10% of an oil-soluble surfactant. The oil-water-soluble diamond grinding paste provided by the invention can ensure the grinding and polishing rate and meet the surface quality requirement, and is easily cleaned.

Description

technical field [0001] The invention belongs to the field of diamond grinding paste grinding and polishing, and in particular relates to an oil-water dual-soluble diamond grinding paste used for precision surface polishing treatment of artificial heart mechanical valve leaflets and a preparation method thereof. Background technique [0002] Artificial heart mechanical valve leaflets are one of the components of mechanical valves. Currently, the mechanical valve leaflets used in clinical practice are mainly made of pyrolytic carbon materials. Pyrolytic carbon has the advantages of high strength, good wear resistance, strong fatigue resistance, good biocompatibility, and light weight. In order to ensure good biological stability of the mechanical valve leaflets in the human body, the finish requirements for the mechanical valve leaflets are extremely high, and the surface needs to be precisely polished. In addition, because pyrolytic carbon is similar to ceramic materials, it...
