Embodiment 1

[0053] Example 1: Lowest cost, good performance, for example, use tin plate, film thickness is 20μm, pencil hardness 2H-3H, adhesion ≤ grade 1, flexibility 0.5mm (r=0.5mm), impact > 50cm, anti-corrosion performance It 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

[0054] 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 2H, the adhesion is ≤ grade 1, and the flexibility is 0.5mm (r=0.5mm) , impact > 55cm, 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

[0055] Example 3: The performance is good, and the anti-rust performance is improved compared with Example 2. For example, a tin plate is used, the film thickness is 20 μm, the pencil hardness is 2H, the adhesion is ≤ grade 1, the flexibility is 0.5mm (r=0.5mm), and the impact is > 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 7 days without blistering and rust.

Abstract

The invention discloses dip-coating water-based paint for a transmission shaft and a preparation method thereof and relates to the technical field of metal water-based paint. The dip-coating water-based paint is prepared from the following raw materials in parts by weight: 20 to 40 parts of waterborne acrylic modified epoxy resin and epoxy modified acrylic resin, 0.3 to 3 parts of a drier, 0.4 to 1.5 parts of a pH (Potential of Hydrogen) regulator, 0.6 to 1.5 parts of a dispersant, 0.3 to 0.5 part of a de-foaming agent, 0.05 to 3 parts of carbon black, 0.01 to 1 part of graphene oxide, 4 to 12 parts of iron oxide black, 2 to 20 parts of antirust pigment, 3 to 8 parts of talcum powder, 0.5 to 8 parts of heavy calcium carbonate, 3 to 8 parts of barium sulfate, 0.05 to 0.15 part of an anti-sedimentation agent, 2 to 3 parts of a film forming auxiliary agent, 0.1 to 0.5 part of a wetting agent, 0.1 to 0.5 part of a leveling agent, 0.1 to 0.5 part of a flash-rust resisting agent, 0.1 to 1.2 parts of a thickener and 10 to 28 parts of water. The water-based paint has the advantages of easiness of improving a film thickness, high rigidity, good wear-resisting and corrosion-preventing effects, capability of being rapidly dried at room temperature and extremely low VOC (Volatile Organic Compounds) content.

Description

technical field [0001] The invention relates to the technical field of metallic water paint. Background technique [0002] With the improvement of people's living standards and the continuous development of the automobile industry, automobiles have become an indispensable means of transportation in people's daily lives. As an important component assembly in the power system of the automobile chassis, the automobile drive shaft is mainly composed of steel, cast iron and other materials. Sand, especially when the car is running at high speed, the sand and gravel on the road surface will impact and scour it, causing the coating to be damaged, thus losing its corrosion resistance, which will affect the performance of the car and the safety of personnel. Therefore, the coating protection of the drive shaft is particularly important. In order to prevent wear and corrosion of the transmission shaft during storage, transportation and use, protective paint is often used to protect ...
