Embodiment 1

[0014] Preparation of slurry 1:

[0015] Put 18 grams of purified water, 1.2 grams of polyacrylic acid ammonium salt dispersant, and 0.03 grams of silicone defoamer into the slurry tank, turn on the speed-adjusting disperser and slowly stir the mixture in the tank for 5-10 minutes at 300 rpm / Min; then slowly add 6 grams of nano tin oxide antimony powder (volume resistance <100Ω·m) into the tank, gradually increase the dispersion speed during the addition, and after the addition, the rotation speed is 700 rpm for 10 minutes; then add The dosage is zirconia beads with a slurry volume of 30-50% and a particle size of 0.6-0.8mm, and the rotation speed is increased until the zirconia beads do not splash out of the tank; the dispersion time is analyzed by transmission electron microscope or laser particle size analyzer, Prove that the particle size of the conductive powder in the slurry is less than or equal to 100nm, and then filter out the zirconia beads.

Description

Technical field [0001] The invention relates to a water-based static conductive paint and a manufacturing method thereof, in particular to a water-based light-colored nano static conductive interior wall paint and a manufacturing method thereof. The paint can be widely used in interior walls of places such as electronics, chemical industry, communications, and computers. Finishing to eliminate the occurrence of bad phenomena caused by static electricity accumulation. Background technique [0002] As polymer materials are widely used in various fields of daily life, their electrostatic hazards have attracted more and more attention. Compared with other materials, anti-static coatings have the advantages of low cost and convenient construction, so they are widely used. In the past, antistatic coatings mostly used carbon black, graphite, mica, metal powders and metal oxides of conventional particle size as conductive fillers. The color of the former is dull, and it is difficult to r...
