Embodiment 1
[0029] Synthesis of water-soluble lubricant:
[0030] a. Mix 10g acrylic acid and 0.09g dibenzoyl peroxide evenly and set aside;
[0031] b. Put 2g of isomeric alcohol polyoxyethylene ether (C 8 H 17 O-(C 2 H 4 O) 8 H) Mix 5g sodium hydroxide, 5g sodium phosphite and 284.9g deionized water, heat up to 90°C and keep it warm for use;
[0032] c. 100g of oxidized polyethylene wax (acid value: 15mgKOH / g, weight average molecular weight: 1000g / mol)
[0033] Mix with 0.01g of dibenzoyl peroxide, stir evenly, raise the temperature to 100°C, then add the mixture in step a dropwise at this temperature for 1 hour; keep at 100°C for 1 hour; then add the mixture in step b The mixture, continue to stir for 10-20 minutes, and mix well.
[0034] d. Cool down to 20°C and filter out the material with a 100-mesh screen.
[0035] The obtained water-soluble lubricant has a weight solid content of 29.78 wt%, a viscosity of 98 mPa.s (measured by NDJ-1 rotational viscometer), and a pH of 7.12 (measured by a P...
