preparation example Construction

[0029] The preparation method of the machining composition and cutting composition of the present invention is not particularly limited, and general mixing methods can be used, such as mixing hexagonal boron nitride, polyols and surfactants evenly, and then the machining composition can be formed. , and then add the processing composition to the abrasive particles, and continue to stir until uniform to form a cutting composition.

[0030] The method for cutting a hard and brittle material according to the present invention is to contact the hard and brittle material with the above-mentioned processing composition, and use a cutting device to cut the hard and brittle material into hard and brittle pieces having many cutting surfaces. The processing composition will allow the hard chips to peel easily from each other and not stick easily.

[0031] The cutting device is well known to those skilled in the art, so it will not be repeated here.

[0032] Preferably, the hard and bri...

Embodiment 1

[0037] Weigh 0.02 parts by weight of hexagonal boron nitride, 2.033 parts by weight of diethylene glycol, 77.64 parts by weight of propylene glycol, 5.082 parts by weight of polyethylene glycol (type PEG-600), 1.016 parts by weight of SINOPOL263, 0.102 parts by weight SW-923, 0.102 parts by weight of SAS-60, 0.203 parts by weight of triethanolamine, 0.02 parts by weight of phthalates, 0.183 parts by weight of octanoic acid and 15.25 parts by weight of water were stirred and mixed at room temperature to obtain processing composition.

Abstract

The invention provides a processing component for cutting hard and brittle materials, comprising hexagonal boron nitrides, solution constituents and surface active agents. The total weight of the solution constituents is 100 part by weight, the content of the hexagonal boron nitrides is 0.01-10 part by weight, but not equal to 0.01 part by weight. When being used for cutting hard and brittle materials, the processing component has the characteristics of high-temperature resistance, good lubricating property, good polishing effect and good cutting capability. When the processing component is cut into a plurality of hard and brittle sheets, the hard and brittle sheets are easy to be separated and uneasy to be bonded. No surface damage of the sheet will occur due to the friction generated by the separation of the hard and brittle sheets, and no breaking of the sheet due to the absorption force generated during cutting will occur. Yield is effectively improved.

Description

technical field [0001] The invention relates to a machining composition and a cutting composition for cutting hard and brittle materials, in particular to a machining composition and a cutting composition containing hexagonal boron nitride. Background technique [0002] Wire saw cutting technology is currently a widely used method for cutting silicon ingots, which can be mainly divided into free abrasive grain method and fixed abrasive grain method. The fixed abrasive method is to fix abrasive particles (such as diamond abrasive particles or silicon carbide abrasive particles) on the steel wire to form a cutting tool, and then use the processing composition to cut the silicon ingot, while the free abrasive method is to use The wire saw is used as a cutting tool, and is then matched with a cutting composition containing abrasive particles and the above-mentioned processing composition to perform the cutting process of the silicon ingot. Regardless of whether the free abrasiv...
