Embodiment Construction

[0021] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Such as figure 1 Shown is the flow chart of the preparation method of the corrosion-resistant paint of the present invention. Visible, the preparation method of corrosion-resistant paint of the present invention comprises the following steps:

[0023] Al first 2 o 3 The surface modification of nano powder is carried out as follows:

[0024] 1) A certain amount of sodium stearate (StearicacidSodiumSalt, referred to as SASS) is dissolved in ethanol and acetone mixed solution to form a primary mixed solution;

[0025] 2) Weigh quantitative Al 2 o 3 Nano powder is added in the three-mouth container, and an appropriate amount of sodium stearate mixed solution is added in the three-mouth container to form a suspension solution;

[0026] 3) The suspension is heated at 50-60°C for a certain period of time under magnetic stirring,...

Abstract

The invention discloses a preparation method of a corrosion-resistant paint used for outer steel plates of ships or automobile shells and capable of resisting erosion resulting from seawater, rainwater or the like.According to a preparation method, stearic acid sodium salt is mainly used for subjecting Al2O3 to surface lipophilic treatment so as to prepare the Al2O3 modified corrosion-resistant paint.The preparation method has the advantages that the stearic acid sodium salt is selected as a surface modification material, hydrophilic and hydrophobic groups similar to coupling agents exist in SASS (stearic acid sodium salt) molecules, and through experimental verifications, after coating treatment of the stearic acid sodium salt, nano-Al2O3 and film-forming matter affinity is enhanced, so that interface bonding force of the film-forming matter is enhanced; hard aggregation forming can be stopped or relieved, good dispersity can be obtained easily, and accordingly mechanical strength of paint coatings is improved and adhesive force is remarkably enhanced.

Description

technical field [0001] The invention relates to a corrosion-resistant paint and a preparation method thereof, in particular to a corrosion-resistant paint used for ship outer steel plates or automobile shells and a preparation method thereof, belonging to the technical field of material coating. Background technique [0002] Ships have to resist the erosion of sea water, because the force of ocean erosion is unparalleled. The ocean is also the harshest testing ground. If there are weaknesses in the ship's construction and protection system, the sea will mercilessly expose them, and constantly reduce the clank of the iron plate to a pile of rusted iron, so most ships will rust. The correct selection and use of steel plate surface treatment and ship paint are particularly important from before, during, and throughout the service life of ship steel plates. [0003] Epoxy resin, polyurethane and other materials are commonly used in corrosion-resistant coatings. They have excel...
