Surface conditioning agent modified zinc phosphate antirust pigment

The invention discloses a surface conditioning agent modified zinc phosphate antirust pigment. The surface conditioning agent modified zinc phosphate antirust pigment is prepared through the followingsteps: adjusting the pH value to 8.0-9.0 by using saturated limewater in a water suspension of zinc phosphate, adding a surface conditioning agent accounting for 0.075-0.500% of the total amount of zinc phosphate to achieve modification, aging for 1-3 h, dehydrating to remove soluble ions, drying at 105-110 DEG C, and pulverizing. The rust resistance of the modified zinc phosphate antirust pigment is improved, the salt water resistance and the salt mist resistance are respectively improved by 1.42-1.56 times and 1.46-1.65 times, and the problems of early antirust deviation, easy flash rust inan aqueous system and the like of a common zinc phosphate antirust pigment are solved. The prepared surface conditioning agent modified zinc phosphate pigment has the advantages of good stability ofa base material, moderate v
