Embodiment 1

[0019] A kind of processing technology of automobile transparent lampshade, described processing technology comprises the steps:

[0020] (1) Processing and molding: first dry the raw material polymethyl methacrylate, then heat it to 240°C to melt, and then cool it in a lampshade mold at a temperature of 35°C to obtain a lampshade blank with strong impact resistance and light transmittance High, at the same time, has strong wear resistance and flame resistance, the drying temperature is 80 ℃, and the drying time is 4h.

[0021] (2) Ultrasonic cleaning: Put the obtained lampshade blank into an ultrasonic cleaning machine for cleaning. The temperature in the ultrasonic cleaning machine is 50°C and the sound wave frequency is 20KHz, which can remove the processing debris on the surface of the lampshade and make the surface of the lampshade smoother. , and high cleaning efficiency.

[0022] (3) Eliminate static electricity: use a static eliminator to eliminate static electricity ...

Embodiment 2

[0027] The rest are the same as in Example 1, except that in the step (1), the thermal melting temperature is 270°C, the lampshade mold temperature is 70°C, the drying temperature is 85°C, and the drying time is 5h , in the step (2), the temperature in the ultrasonic cleaning machine is 85°C, the sound frequency is 40KHz, in the step (4), the thickness of the UV-curable coating is 0.02mm, and the step ( In 5), the thickness of the anti-fog film is 0.015 mm, and in the step (6), the roughness of the outer surface of the edge of the lampshade blank is 100.

Embodiment 3

[0029] The rest are the same as in Example 1, except that in the step (1), the thermal melting temperature is 265°C, the lampshade mold temperature is 65°C, the drying temperature is 80°C, and the drying time is 4.5 h, in the step (2), the temperature in the ultrasonic cleaning machine is 80°C, and the sound frequency is 30KHz; in the step (4), the thickness of the UV-curable coating is 0.015mm, In (5), the thickness of the anti-fog film is 0.012 mm, and in the step (6), the roughness of the outer surface of the edge of the lampshade blank is 80.

[0030] In the above three examples, the obtained automobile transparent lampshade has strong impact resistance, strong wear resistance and flame resistance, a visible light transmittance of 92%, high hardness, good safety, convenient installation and firm structure.

[0031] It is known from practical application that in the process of lampshade processing, polymethyl methacrylate is selected as the raw material for lampshade proces...

Abstract

The invention discloses a processing technology for a transparent lampshade for an automobile, which relates to the field of processing lamps and lanterns for automobiles, including six steps of processing and molding, ultrasonic cleaning, static electricity elimination, spraying treatment on the outer surface, anti-fog coating on the inner surface, and edge grinding. As a raw material for lampshade processing, methyl methacrylate has strong impact resistance, high light transmittance, strong wear resistance and flame resistance. A layer of anti-fog film is coated on the inner surface of the lampshade blank to prevent water from forming in the lampshade. Fog is conducive to the safe driving of the car. The frosting treatment on the edge of the lampshade blank can increase the roughness of the outer surface of the lampshade blank edge and make the installation of the lampshade more secure.
