Embodiment 1

[0050] An electrostatic powder spraying process for children's dining chair accessories, step S1 specifically includes the following steps:

[0051] S1.1 Substrate surface pretreatment:

[0052] S1.1.1 Perform two liquid blasting treatments on the surface of the substrate. The first liquid sand blasting uses a sand particle size of 0.1 mm, the second liquid sand blasting uses a sand particle size of 0.5 mm, and the first liquid sand blasting uses a sand particle size of 0.5 mm. The duration of the liquid blasting treatment is 30s, the duration of the second liquid blasting treatment is 10s, and the angle between the blasting direction of the first liquid blasting treatment and the blasting direction of the second liquid blasting treatment is greater than 0° And less than 180°;

[0053] S1.1.2 Degreasing the surface of the substrate after the treatment in step S1.1.1;

[0054] S1.1.3 Dry the base material after degreasing treatment in step S1.1.2 with hot air at 40°C for 3 mi...

Embodiment 2

[0073] An electrostatic powder spraying process for children's dining chair accessories, step S1 specifically includes the following steps:

[0074] S1.1 Substrate surface pretreatment:

[0075] S1.1.1 Perform two liquid blasting treatments on the surface of the substrate. The first liquid sand blasting uses a sand particle size of 0.2 mm, the second liquid sand blasting uses a sand particle size of 1 mm, and the first liquid sand blasting uses a sand particle size of 1 mm. The duration of the sandblasting treatment is 30s, the duration of the second liquid sandblasting treatment is 10s, the angle between the sandblasting direction of the first liquid sandblasting treatment and the sandblasting direction of the second liquid sandblasting treatment is greater than 0° and Less than 180°;

[0076] S1.1.2 Degreasing the surface of the substrate after the treatment in step S1.1.1;

[0077] S1.1.3 Dry the base material after degreasing treatment in step S1.1.2 with hot air at 50°C...

Embodiment 3

[0096] An electrostatic powder spraying process for children's dining chair accessories, step S1 specifically includes the following steps:

[0097] S1.1 Substrate surface pretreatment:

[0098] S1.1.1 Perform two liquid blasting treatments on the surface of the substrate. The first liquid sand blasting uses a sand particle size of 0.1 mm, the second liquid sand blasting uses a sand particle size of 0.8 mm, and the first liquid sand blasting uses a sand particle size of 0.8 mm. The duration of the liquid blasting treatment is 30s, the duration of the second liquid blasting treatment is 10s, and the angle between the blasting direction of the first liquid blasting treatment and the blasting direction of the second liquid blasting treatment is greater than 0° And less than 180°;

[0099] S1.1.2 Degreasing the surface of the substrate after the treatment in step S1.1.1;

[0100] S1.1.3 Dry the base material after degreasing treatment in step S1.1.2 with hot air at 45°C for 4 mi...

Abstract

The invention relates to an electrostatic powder spraying technique for a part of a child dinning chair. The electrostatic powder spraying technique for the part of the child dinning chair comprises the following steps that S1, a bonding layer (1) is prepared, specifically, bonding agent powder is sprayed onto the surface of a base material through a spray gun; S2, a protection layer (2) is prepared, specifically, raw material powder for the protection layer is sprayed onto the surface of the bonding layer (1) prepared in the step S1 through the spray gun; and S3, a waterproof layer (3) is prepared, specifically, waterproof paint is evenly smeared on the surface of the protection layer (2) prepared in the step S3. The electrostatic powder spraying technique for the part of the child dinning chair has the advantages that the cost is low, attractiveness is ensured, and the coatings are not prone to being damaged by external force.

Description

technical field [0001] The invention relates to the technical field of surface engineering, in particular to an electrostatic powder spraying process for children's dining chair accessories. Background technique [0002] Electrostatic spraying: The working principle of the electrostatic powder spraying method is almost exactly the same as that of the general liquid paint electrostatic spraying method, the difference is that the powder spraying is dispersed rather than atomized. It is a coating sprayed by an electrostatic powder spray gun. While dispersing, the powder particles are negatively charged. The charged powder particles are applied to the object to be coated by the action of airflow (or other forces such as centrifugal force) and electrostatic attraction. , and then heated to melt and solidify into a film. Electrostatic powder spraying method is the dominant powder coating method in the field of industrial coating. [0003] Epoxy resins generally refer to organic ...
