Problems solved by technology

[0003] With the continuous development of various modern fields, the demand for abrasive paste is also increasing. The abrasive paste has the economic effect of wear resistance and durability, but the current grinding effect has not yet developed to an ideal state, and the surface roughness does not meet the technical requirements. The product rate Low
The existing grinding paste powder has poor dispersion characteristics, the microscopic geometry of the main grinding materials is not ideal, the particle size range of the grinding material particles is too wide, and the component lubrication properties are not good, which makes the surface quality of the material after grinding and polishing unsatisfactory, and it is difficult to achieve Quality requirements, the qualified rate of ground products is low
Although most grinding pastes and grinding fluids can enhance the grinding effect, they are easy to damage the grinding machine during use
In addition, since the grinding fluid is in liquid form, it is easy to cause waste in use, thereby increasing production costs
However, the existing grinding paste has poor cleanliness, and the grinding paste is easily corroded by bacteria and loses its original effect.

Abstract

The invention discloses water-oil soluble nanocarbon crystal abrasive paste. The water-oil soluble nanocarbon crystal abrasive paste is mainly prepared from, by weight, 10-25 parts of nano carbon crystals, 1-10 parts of water, 20-30 parts of oleic acid, 10-20 parts of vaseline, 15-30 parts of kerosene, 15-25 parts of peanut oil, 5-15 parts of fungicide, 0.2-2 parts of sorbitan fatty acid ester and 0.2-2 parts of an OP-emulsifier. The invention further discloses a preparation method of the water-oil soluble nanocarbon crystal abrasive paste. The prepared abrasive paste has the advantages of being green, environmentally friendly, non-corrosive, low in cost and good in grinding effect and is applicable to measuring tools, cutting tools and optical instruments made from glass, ceramic, hard alloy, natural diamonds, precious stones and other hard materials and machining of other high-finish-degree workpieces.

Description

technical field [0001] The invention relates to a grinding paste for grinding and polishing, in particular to a water-oil two-soluble nano-carbon crystal grinding paste and a preparation method thereof. Background technique [0002] Grinding paste can be divided into oil-soluble grinding paste and water-soluble grinding paste. Oil-soluble grinding paste has good wettability, small grinding force and low grinding heat, and is mainly used for processing parts of high-hard alloy materials such as hard alloy with high finish. Instruments, measuring tools, cutting tools, grinding tools, etc. Water-soluble abrasive paste has low viscosity, easy cutting and high processing efficiency. It is mainly used for processing slightly corroded metals, circuit boards, glass, ceramics, gemstones, agate and other non-metallic hard and brittle materials. Commonly used abrasive pastes mainly include different types of abrasive pastes such as corundum, silicon carbide and boron carbide, chromium...
