Example Embodiment
[0020] Example one:
[0021] The production process of hexagonal boron nitride modified drawing lubricant for enameled wire includes the following steps:
[0022] a. Choose crystal particles of 3~25μm, purity> Hexagonal boron nitride with 98.5% and a specific surface area of 2-18㎡ / g is added to deionized water with hexagonal boron nitride powder. The weight ratio of hexagonal boron nitride and deionized water is 1:5 to obtain a mixture;
[0023] b. Heat the mixture to 50-70°C and stir for 10 minutes to obtain a mixture;
[0024] c. In parts by weight, the 1:10 mixture and copper wire emulsified lubricant are sheared at high speed on a shearing emulsifier for 30 minutes at a speed of 15000-20000rpm to obtain a hydrated emulsion; high-speed shearing, collision , After crushing, the materials in the tank are mixed uniformly, so as to reach the state of hydration and emulsification;
[0025] d. In parts by weight, add 3.0-4.0% hydrated emulsion to the drawing lubricating tank / box contain...
