Embodiment 1

[0020] Prepare strontium nitrate and 0.8 mol / L sodium phosphate solutions with a concentration of 1.2 mol / L respectively, measure 25 mL of the above two solutions and place them in two beakers, add 0.2 g of benzene to the strontium nitrate and sodium phosphate solutions respectively Triazole and 0.05g polyethylene glycol, stirred until fully dissolved. Place the strontium nitrate solution and the sodium phosphate solution on both sides of the egg membrane respectively. After reacting for 12 hours, take the precipitate, wash it with deionized water three times, put it in an oven, and dry it at 60°C for 12 hours to obtain the strontium phosphate base. Nano-assembled spherical anti-corrosion pigments. The overall diameter of the obtained strontium phosphate-based nano-assembled spherical anticorrosion pigment is about 2.5 μm, and the thickness of the nanoribbon assembled into the nano-assembled sphere is about 30 nm. The anti-corrosion pigment is added to the paint to make a pai...

Abstract

The invention belongs to the technical field of material chemistry and particularly relates to a preparation method of strontium phosphate-based nano-assembling spherical anticorrosive pigment. The strontium phosphate-based nano-assembling spherical anticorrosive pigment is of an ordered structure assembled by nanobelts, and the surface of the pigment can be firmly composited with benzotriazole and a surfactant. The strontium phosphate-based nano-assembling spherical anticorrosive pigment 2-3 micrometers in overall diameter and prepared from the nanobelts 20-30 nm thick has the advantages of good dispersity, excellent compatibility and excellent corrosion resistant performance.

Description

technical field [0001] The invention belongs to the field of material chemistry, and in particular relates to a strontium phosphate-based nano-assembled spherical anti-corrosion pigment and a preparation method thereof. Background technique [0002] The biggest advantage of phosphate series anti-corrosion pigments is that they are environmentally friendly and belong to non-toxic anti-corrosion pigments. Phosphate has good compatibility in various coating systems, and under high temperature conditions, phosphate can produce pyrophosphate that is more stable and less volatile. In silicone high-temperature coating products, phosphate is also a better anti-corrosion agent. rust paint. At present, the main types of relatively mature phosphate series products in the market are orthophosphate, polyphosphate, pyrophosphate and metaaluminate. [0003] As an important phosphate, strontium phosphate is often used in the field of luminescent materials and cement modified fillers. As ...
