[0002] The car dashboard is an assembly that installs various indicating instruments and ignition switches in the cab. At the same time, it is the control center of some equipment and the object to be decorated. It is the most eye-catching part in the cab. The dashboard assembly It has both technical and artistic functions, and is one of the representatives of the style of the vehicle; however, the car dashboard is made of plastic and is located at the front of the cab. Aging, discoloration, hardening and brittleness appear, which reduces the practicality and decoration of the dashboard
[0003] At present, in order to improve the anti-aging performance of the instrument panel, most of the chemical reagents with anti-aging properties are added in the preparation process to improve the cross-linking ability of the raw materials and delay the aging of the plastic board. However, the anti-aging reagents are toxic. The process will cause harm to the human body, and the addition of anti-aging agents will make the preparation process more cumbersome to adjust the strength of the dashboard, and the addition of anti-aging agents will not change the appearance and decorative properties of the dashboard

Embodiment 1

[0021] An anti-aging surface treatment method for an automobile instrument panel, comprising the following steps:

[0022] (1) Dust removal: Clean the plastic molded instrument panel in a sodium chloride solution with a mass concentration of 1.2%, and use an electrostatic gun to remove surface static electricity, remove impurities on the surface of the instrument panel, and facilitate post-processing to obtain a dust-removed instrument panel;

[0023] (2) Degreasing: first use 0.7% sodium hydroxide solution to clean the dust removal instrument panel, rinse it twice, then use absolute ethanol to clean it three times, and finally rinse it with pure water to remove the grease on the surface of the instrument panel , so that the late surface treatment agent and the instrument panel are closely combined to obtain a degreasing instrument panel;

[0024] (3) Annealing: place the degreasing instrument panel at 72°C and heat it at a constant temperature for 150 minutes to eliminate the...

Embodiment 2

[0031] An anti-aging surface treatment method for an automobile instrument panel, comprising the following steps:

[0032] (1) Dust removal: Clean the plastic molded instrument panel in a sodium chloride solution with a mass concentration of 1.3%, and use an electrostatic gun to remove surface static electricity, remove impurities on the surface of the instrument panel, and facilitate post-processing to obtain a dust-removed instrument panel;

[0033] (2) Degreasing: first use 0.8% sodium hydroxide solution to clean the dust removal instrument panel, rinse it twice, then use absolute ethanol to clean it 4 times, and finally rinse it with pure water to remove the grease on the surface of the instrument panel , so that the late surface treatment agent and the instrument panel are closely combined to obtain a degreasing instrument panel;

[0034] (3) Annealing: place the degreasing instrument panel at 74°C and heat it at a constant temperature for 180 minutes to eliminate the int...

Embodiment 3

[0041] An anti-aging surface treatment method for an automobile instrument panel, comprising the following steps:

[0042] (1) Dust removal: Clean the plastic molded instrument panel in a sodium chloride solution with a mass concentration of 1.4%, and use an electrostatic gun to remove the surface static electricity and impurities on the surface of the instrument panel, which is beneficial for post-processing, and the dust-removed instrument panel is obtained;

[0043] (2) Degreasing: first use 0.9% sodium hydroxide solution to clean the dust removal instrument panel, wash it repeatedly for 3 times, then use absolute ethanol to clean it 4 times, and finally rinse it with pure water to remove the grease on the surface of the instrument panel , so that the late surface treatment agent and the instrument panel are closely combined to obtain a degreasing instrument panel;

[0044] (3) Annealing: place the degreasing instrument panel at 76°C and heat it at a constant temperature fo...

Abstract

The invention mainly relates to the technical field of machining of automobile products and discloses an anti-aging surface treatment method for an automobile instrument panel. The method comprises the steps of dust removal, oil removal, annealing, primary spraying, secondary spraying, ultraviolet curing and nano processing; The anti-aging surface treatment method for the automobile instrument panel is simple, the obtained automobile instrument panel has a metal texture, high strength and excellent anti-aging performance, aging caused by ultraviolet rays to the instrument panel can be delayed,discoloration and hardening of the instrument panel are prevented, and the use and decoration performance of the instrument panel is improved. Dust and static electricity are removed from the formedplastic instrument panel first, and impurities on the surface of the instrument panel are removed, so that post-treatment is facilitated; after dust removal, a sodium hydroxide solution, absolute ethanol and pure water are used in sequence for cleaning to remove grease on the surface of the instrument panel, so that a surface treatment agent is tightly bonded to the instrument panel in the later period.
