Problems solved by technology

The motor casing is mainly composed of steel materials, and there are many heat sinks, which make the exposed area larger. Because of its wide range of applications, the contact environment is relatively complex, so the motor casing is more likely to be damaged due to corrosion.

Embodiment 1

[0054] Example 1: The cost is relatively low and the performance is good. For example, use a tinplate plate, the film thickness is 20 μm, the pencil hardness is H-2H, the adhesion is ≤ grade 1, the flexibility is 0.5mm (r=0.5mm), the impact is > 50cm, and it is anti-corrosion The performance is mainly reflected in the neutral salt spray performance, the film thickness is 60μm, and the salt spray test can reach 5 days without blistering and rust.

Embodiment 2

[0055] Embodiment 2: The cost is relatively low, the performance is good, and the antirust performance is improved compared with Example 1. For example, a tinplate plate is used, the film thickness is 20 μm, the pencil hardness is H-2H, the adhesion is ≤ grade 1, and the flexibility is 0.5mm (r=0.5 mm), impact > 50cm, anti-corrosion performance is mainly reflected in the neutral salt spray performance, the film thickness is 60μm, and the salt spray test can reach 6 days without blistering and rust.

Embodiment 3

[0056] Embodiment 3: Good performance, antirust performance is improved compared with Example 2, for example, use tin plate, film thickness is 20 μ m, pencil hardness H-2H, adhesion ≤ grade 1, flexibility 0.5mm (r=0.5mm), impact >55cm, the anti-corrosion performance is mainly reflected in the neutral salt spray performance, the film thickness is 60μm, and the salt spray test can reach 8 days without blistering and rust.

Abstract

The invention discloses an acrylic water-based paint for motor shells and a preparation method thereof, relating to the technical field of metal water-based paints. The acrylic water-based paint for motor shells comprises the following raw materials in parts by weight: 45-50 parts of acrylic modified resin, 0.4-0.8 part of pH regulator, 0.6-1.5 part of dispersing agent, 0.3-0.5 part of defoaming agent, 0.01-0.5 part of graphene oxide, 0.05-3 parts of carbon black, 10-20 parts of rutile titanium white, 2-10 parts of antirust pigment, 0.5-4 parts of matting powder, 0.5-8 parts of ground calcium carbonate, 3-8 parts of barium sulfate, 0.05-0.15 part of anti-settling agent, 2-3 parts of film forming aid, 0.1-0.5 part of wetting agent, 0.1-0.5 part of leveling agent, 0.1-0.5 part of flash-rust inhibitor, 0.1-1.2 parts of thickener and 6-16 parts of deionized water. The water-based paint has the advantages of favorable antirust effect, quick air-drying, high adhesive force and high hardness; and by using water as the diluter, the water-based paint satisfies the environmental requirements, and is harmless to the human body.

Description

technical field [0001] The invention relates to the technical field of metallic water paint. Background technique [0002] The motor is mainly composed of metal materials and has been widely used in all walks of life. It is an important guarantee for industry, agriculture, national defense construction and people's life. Therefore, it is very important to ensure the normal operation of the motor. The motor casing is mainly composed of steel materials, and there are many heat sinks, which make the exposed area larger. Because of its wide range of applications, the contact environment is relatively complex, so the motor casing is more likely to be damaged due to corrosion. . This requires that the motor coating not only has excellent adhesion, flexibility, impact resistance and good hardness, but also has good anti-corrosion performance and good chemical resistance. [0003] my country's motor industry has a huge demand for industrial coatings. But at present, the industria...
