Complex dispersant water-based liquid magnetic grinding tool and manufacturing method thereof

The invention disclose a complex dispersant water-based liquid magnetic grinding tool and a manufacturing method thereof, and belongs to the field of surface finishing of mechanical parts. The high-stability complex dispersant water-based liquid magnetic grinding tool is made of raw materials including, by mass percent, 65% to 80% of magnetic particles, 15% to 25% of deionized water, 0.5% to 3% of a surface active agent, 0.5% to 2% of an antioxidant, 0.3% to 1% of a moisturizing agent, 0.3% to 1.5% of a pH adjusting agent, 1% to 2% of nanoscale particles, and 7% to 10% of abrasive particles. The grinding tool has the beneficial effects the stirring manner based on seal pure rolling is provided, a complex dispersant is used and is combined with other function reagents to replace a single dispersant, the moisturizing agent is added in the formula, the water evaporation is reduced, the nanoscale particles are added, the effect of filling gaps between macromolecules is achieved, the space position resistance effect is improved, and the grinding tool has the beneficial effects of being stable, good in re-dispersion, good in fluidity, low in zero field viscosity, non-poisonous and convenient to recycle.
