Problems solved by technology

[0004] However, most of the water-based coolant solvents currently used for fixed abrasive wire cutting are water, and the amount of water used is large. Due to the effects of various components in the coolant and air, it will cause corrosion to the wire cutting machine and make the equipment The cutting accuracy decreases, which reduces the service life of the wire cutting machine and increases the maintenance cost

[0040] The present invention also provides a method for preparing a water-soluble cutting fluid for fixed abrasive wire cutting, comprising:

[0041] Mixing the antirust agent with water to obtain a first solution;

[0042] Mixing the nonionic surfactant with water to obtain an aqueous surfactant solution;

[0043] Adding an antifoaming agent and a lubricant to the aqueous surfactant solution in turn to obtain a second solution;

[0044] mixing the first solution with the second solution to obtain a water-soluble cutting fluid for fixed abrasive wire cutting;

[0045] Among them, the raw materials include: 0.1% to 10% of non-ionic surfactant; 2% to 20% of antirust agent; 4% to 20% of lubricant; 0.1% to 2% of defoamer according to the weight percentage of the total amount of cutting fluid; The balance is water; the antirust agent is one or more of organic alcohol amine compounds, nitrite or benzotriazole and its derivatives.

[0046] According to the present invention, the r...

Embodiment 1

[0055] 1. Weigh and mix 20 parts by weight of triethanolamine and water, and stir evenly to make a uniform and transparent solution.

[0056] 2. Weigh 0.1 parts by weight of nonylphenol polyoxyethylene ether, 0.1 parts by weight of silicone oil, 5 parts by weight of polyethylene glycol and water, and mix and stir evenly to obtain a surfactant solution.

[0057] Mix the transparent solution prepared in 1 and 2 with the surfactant solution, and stir evenly to obtain a water-soluble cutting fluid for fixed abrasive wire cutting.

Embodiment 2

[0060] 1. Weigh and mix 10 parts by weight of triethanolamine and water, and stir evenly to make a uniform and transparent solution.

[0061] 2. Weigh 1 part by weight of nonylphenol polyoxyethylene ether, 1 part by weight of silicone oil, 15 parts by weight of polyethylene glycol and water, and mix and stir evenly to obtain a surfactant solution.

[0062] Mix the transparent solution prepared in 1 and 2 with the surfactant solution, and stir evenly to obtain a water-soluble cutting fluid for fixed abrasive wire cutting.

[0063] Through the cutting fluid workshop experiment, the results show that the cutting fluid can meet the cutting requirements of the fixed abrasive wire saw, and the overall performance is better. From the comprehensive consideration of economic benefits and slicing effects, embodiment 2 is the best. The detection performance is shown in Example 2 in Table 1.

The present invention further provides a preparation method for the water-soluble cooling liquid for fixed abrasive material line cutting.

Description

technical field [0001] The invention relates to the technical field of photovoltaic manufacturing, in particular to a water-soluble cooling liquid for fixed abrasive wire cutting and a preparation method thereof. Background technique [0002] With the rapid development of the photovoltaic industry, in order to reduce the cost of manufacturing photovoltaic modules and improve the efficiency of silicon wafer cutting, wire cutting technology has emerged. The edge precision of silicon wafers prepared by wire cutting technology is high, smooth and smooth, with high degree of automation, saving time and improving processing efficiency. There are two kinds of wire cutting technology methods, (1): free abrasive wire cutting technology is the mainstream technology now, and the oily cutting fluid is mainly used. In order to make the cutting edge suspend in the cutting fluid, a large amount of organic high Molecular viscous liquid is used as cutting fluid. This viscous organic polymer...
