Example Embodiment

[0028] Example 1:

[0029] The boron nitride anticorrosive coating material of this embodiment is composed of the following parts by weight: 23 parts of water-based alkyd resin, 6 parts of nano boron nitride with an average particle size ≤120nm, 1.2 parts of polysiloxane sodium salt dispersant, fluorine-based flow 1.5 parts of ping agent and 75 parts of solvent, of which the solvent is composed of m-xylene, cycloethyl ketone and ethyl glycol ether in a volume ratio of 2:3:1.

[0030] The preparation method is as follows: firstly use a ball mill to grind the nano boron nitride uniformly, then mix it with a solvent to prepare a boron nitride slurry, and then add a dispersant to the prepared boron nitride slurry to prepare a boron nitride filler dispersion Finally, the boron nitride filler dispersion prepared above is mixed with the water-based alkyd resin to be stable and uniformly dispersed to prepare the boron nitride anticorrosive coating material.

Example Embodiment

[0031] Example 2:

Abstract

The invention relates to a boron nitride anti-corrosion coating material and a preparation method thereof, and belongs to the field of chemical engineering. The boron nitride anti-corrosion coating material is composed of the following components in parts by weight: 22-24 parts of water-based alkyd resin, 5-7 parts of nano boron nitride, 0.6-1.6 parts of a dispersant, and 70-85 parts of a solvent.The preparation method comprises the following steps: a, mixing the nano boron nitride and the solvent to prepare a boron nitride slurry; b, adding the dispersant into the prepared boron nitride slurry to prepare a boron nitride filler dispersion liquid; and c, mixing the prepared boron nitride filler dispersion liquid and the water-based alkyd resin to prepare the boron nitride anti-corrosion coating material. The preparation method of the anti-corrosion coating material provided by the invention is simple, and the prepared coating has a thickness range of 20-25[mu]m, can protect a substratematerial for 7-8 years under the high-temperature environment of 300 DEG C, and has excellent anti-corrosion effects.

Description

technical field [0001] The invention relates to an anti-corrosion coating material, in particular to a boron nitride anti-corrosion coating material and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] Metal corrosion is a spontaneous process that has always brought serious losses to human production and life, even catastrophic accidents. Corrosion is actually a great damage and waste of natural resources. Damage or fracture of metal may not only cause leakage of harmful substances, but also cause environmental pollution. In addition, if corrosion damage occurs in a certain key part and fails to receive timely attention and treatment, it may cause sudden catastrophic accidents, endanger the safety of daily production and life, and bring great losses to the national economy. and hazards. [0003] According to statistics, developed countries will consume about 10-20% of metals due to corrosion every year, and the econom...
