Embodiment Construction

[0029] The specific embodiment of the present invention is as figure 1 As shown, the steps are as follows:

[0030] Weigh 20g of deionized water and add it to a 100mL beaker, then add 1.5g of ammonium carbonate and 15.0g of 25% ammonia water to the beaker, and stir with a magnetic stirrer to completely dissolve the ammonium carbonate to prepare a compound solution.

[0031] Weigh 1.0g of zinc oxide, add it to the beaker of the compound solution, then weigh 0.2g polyethylene glycol-2000 dispersant, add it to the beaker of the compound solution, and carry out ultrasonic dissolution for 30min, stirring continuously during the ultrasonic process, It was completely dissolved into a colorless transparent solution.

[0032] Put the 100mL beaker containing the colorless and transparent solution into a water bath at 70-75°C, and stir at a speed of 300r / min until the colorless and transparent solution becomes slightly cloudy, then immediately take out the 100mL beaker and pour it into ...

Abstract

The invention discloses a preparation method of nanometer sheet-shaped zinc phosphate. The preparation method comprises 1, dissolving zinc oxide, 2, preparing a nanometer sheet-shaped zinc phosphate precursor and 3, preparing nanometer sheet-shaped zinc phosphate. The nanometer sheet-shaped zinc phosphate has an obvious lamellar structure and no obvious agglomeration. The nanometer sheet-shaped zinc phosphate is used in paint, produces labyrinth effects, increases water transmission paths and prolongs a coating service life. The preparation method has simple requirements on experiment conditions, utilizes the raw materials with a wide source, realizes recovery and recycle of a waste liquid, saves an economic cost and has environmental protection benefits. The preparation method is suitable for preparation and production of the nanometer sheet-shaped zinc phosphate.

Description

[0001] technical field [0002] The invention relates to a preparation method of nano-flaky zinc phosphate, belonging to the technical field of protective coatings. Background technique [0003] The corrosion of metal materials has caused a great waste of materials. Protective coatings can effectively improve the corrosion resistance of metal materials, so protective coatings are widely used on the surface of metal equipment. [0004] Some of the equipment with protective coatings are used in water-containing environments, such as ships, offshore oil fields, underground natural gas pipelines, etc. It is difficult for general protective coatings to overcome the harsh conditions in water-containing environments. Therefore, pigments with certain functional activity are added to the coating to increase the life of the coating and reduce maintenance costs. But at present, most of the applied pigments are chromates, lead pigments, molybdates, metaborate pigments, and ordin...
