Description

Technical Field

[0001] The invention relates to a cutting fluid and application thereof. Background Art

[0002] Currently, cutting fluid is usually used in the process of cutting stone. However, when using the existing known cutting fluid for cutting, due to the heavy foam of the existing fatty alcohol polyether, overflow may occur and the cutting effect may be affected; thus, problems such as wire breakage and scratches may be caused during the cutting process, resulting in low cutting efficiency and poor cutting effect. Summary of the invention

[0003] In order to overcome the defects of the prior art in which cutting fluid is used in the process of cutting stone, such as wire breakage and scratches, resulting in low cutting efficiency and poor cutting effect, the present application provides a cutting fluid and its application; the cutting fluid has excellent lubricating and dispersing properties, so that it has a better cutting effect; specifically, the cutting fluid can reduce the wire breakage rate, scratch rate and torque.

[0004] The present invention provides a cutting fluid, which comprises the following components based on a mass fraction of 100%:

[0005] 1%~10% wetting agent, 10%~20% lubricant, 0.5%~3% defoaming agent, 0.5%~2% sedimentation agent, 1%~5% anti-rust additive, 3%~10% auxiliary agent, and the balance is water; % is the mass percentage of each component in the cutting fluid;

[0006] Wherein, the wetting agent includes fatty alcohol polyether; the fatty alcohol polyether is a polymer as shown in formula I:

[0007] Formula I;

[0008] R is selected from C8~C 14 A hydrocarbon group, n is selected from an integer of 1 to 10, and m is selected from an integer of 1 to 5;

[0009] The lubricant comprises trans-block polyether, polyether ester or polyethylene glycol; or, the lubricant comprises trans-block polyether and polyether ester; or, the lubricant comprises trans-block polyether and polyethylene glycol.

[0010] In the present invention, by selecting a specific fatty alcohol polyether, an excellent wetting effect can be exerted, and in combination with other components, the cutting fluid of the present application has excellent lubrication and dispersion properties, so that it has a lower wire breakage rate, scratch rate and torque and other better cutting effects, avoiding overflow during the cutting process, which affects the cutting effect.

[0011] In the present invention, in the structure of the fatty alcohol polyether of formula I, a specific amount of propylene oxide is connected after ethylene oxide, which not only has hydrophobicity, but also can effectively suppress foam. When the content of propylene oxide in the fatty alcohol polyether is too large, the solubility is poor, the cloud point is on the low side, and the temperature rise will separate from the system to make the solution turbid. At the same time, it is unstable in water and easily separates from the system, thereby affecting the life and cutting performance of the cutting fluid. When the content of propylene oxide in the fatty alcohol polyether is too small, the foam type of the raw material will deteriorate, resulting in a high amount of foam during cutting, which also affects the cutting performance of the cutting fluid.

[0213] Effect Example 1

[0214] This effect embodiment examines the cutting experiment of Examples 1-8 and Comparative Examples 1-3 in the marble cutting process, and studies the actual application effects of Examples 1-8 and Comparative Examples 1-3.

[0215] The above examples 1-8 were diluted with deionized water at a ratio of 1: (100-200) and cut with marble under the same cutting parameters (using a 550 micron carbon steel wire diameter, a cutting line speed of 17 m / s, and a left and right line tension of about 150-180 N). The surface of the marble was relatively rough and the texture was relatively soft, so the resistance was relatively small during the cutting process. The size of the marble was about 2000 mm*2000 mm*3000 mm, and it was cut with a multi-wire diamond wire. Table 1 shows the cutting effect data of the cutting fluid:

[0216] Table 1

[0217]

[0218] From the data in Table 1, it can be seen that the wire breakage rate, scratch rate, and torque of the cutting fluid of Examples 1-8 are 10.22% and below, 2.01% and below, and 129Nm and below, respectively, while the wire breakage rate, scratch rate, and torque of the cutting fluid of Comparative Examples 1-3 are 12.53% and above, 2.32% and above, and 141Nm and above. It can be seen that compared with the cutting fluid of Comparative Examples 1-3, the cutting fluid of Examples 1-8 has better lubricity and has obvious advantages in the highest torque, wire breakage rate, and scratch rate data during the cutting process. It can be seen that the use of the cutting fluid of the present application can reduce the torque value, which reflects that the cutting fluid has a good lubrication effect and the resistance encountered during the cutting process is small.
