Problems solved by technology

[0002] Piezoelectric crystals and piezoelectric ceramics have been widely used in various fields of people's daily life (such as color TV, audio, computer, mobile phone, clocks, toys, etc.), especially in the fields of communication, aerospace, national defense, etc., and the development is more rapid. To manufacture various piezoelectric devices with different frequencies, the piezoelectric materials must be precisely ground. In order to achieve the precision of grinding, the grinding liquid is required to have excellent suspension and dispersion ability for the abrasive. At present, the common water-based anti-rust agent cannot meet the requirements. Large-grained abrasives can really suspend fine processing requirements, while ordinary oils cannot suspend abrasives. Even though specially processed special oil ("PC" oil) cannot be recycled due to the incorporation of a large amount of abrasives in the grinding process, it will cause environmental pollution. Pollution, more importantly, piezoelectric quartz crystals require special cleaning on the surface of electronic components, and the surface after grinding with "PC" oil has a lot of oil stains. The pollution of piezoelectric devices is not easy to clean and affects the quality of products

Embodiment 1

[0021] 1. Weigh 50kg of pure water and 2.5kg of bentonite, stir thoroughly, and let stand for 2 days to fully flocculate and remove impurities. Add 3 kg of calcium polyacrylate to the bentonite solution after removing impurities, fully stir at room temperature (20°C) for 30 minutes, and then let it stand under a pressure of less than 0.1 MPa. After 3 days, a milky white gel-like suspension is obtained ,spare.

[0022] 2. Add 1,040g of acetamide and 3,120g of isopropanolamine into a 5,000ml three-necked reaction flask, stir and blow in nitrogen gas, gradually raise the temperature to 140°C, reflux for 4 hours, take samples for analysis every half hour, and use the acid-base titration method to determine, When the titration curve changes, it is considered that the reaction is complete, and the light yellow viscous liquid is obtained, which is the antirust agent (C). Get 3kg for subsequent use.

[0023] 3. Weigh 0.4kg of sodium stearate and 0.1kg of Pingpingjia-20.

Weigh 50kg of pure water, 2kg of organic bentonite, stir well and evenly, add 0.4kg of polyacrylamide, 2kg of triethanolamine, 0.2kg of TX-10, and stir fully for 30 minutes at room temperature (20°C), then Stand under MPa pressure condition, obtain milky white gel-like suspension after 3 days for subsequent use.

[0027] 2. Prepare rust preventive agent (C) 3kg by embodiment one for subsequent use.

[0028] 3. Weigh 0.5 kg of sodium stearate.

[0029] The above components by weight are uniformly mixed to obtain the high-suspension-power water-soluble anti-rust grinding liquid of the present invention.

Embodiment 3

[0031] 1. Weigh 50kg of pure water and 2.5kg of bentonite, stir thoroughly, and let stand for 2 days to fully flocculate and remove impurities. Add 5 kg of carbonyl isopropanolamine to the bentonite solution after removing impurities, fully stir at room temperature (20° C.) for 30 minutes, then stand under a pressure of less than 0.1 MPa, and obtain a milky white gel-like suspension after 3 days. .

[0032] 2. Add 940g of acetamide and 3870g of diethanolamine to a 5000ml reaction bottle, and reflux at 140°C for 4 hours under the protection of nitrogen to obtain a light yellow viscous liquid, which is the rust inhibitor (C). Take 3kg for later use.

[0033] 3. Weigh 0.4kg of sodium stearate and 0.1kg of Pingpingjia-20.

[0034] The above components by weight are uniformly mixed to obtain the high-suspension-power water-soluble anti-rust grinding liquid of the present invention.
