Embodiment 1

[0023] like Figure 1 to Figure 2 As shown, the present invention provides a decorative tail pipe of an automobile exhaust pipe, comprising a connecting pipe 1 and an exhaust pipe 2 communicating with the connecting pipe 1 .

[0024] Specifically, the diameter of the connecting pipe 1 is larger than the diameter of the air outlet pipe 2, one end of the connecting pipe 1 is open, and the other end is communicated with the air outlet pipe 2; In this embodiment, the number of carbon fiber arc-shaped plates 3 is 4, and the carbon fiber arc-shaped plates 3 are screwed to the connecting pipe 1 through studs 4 .

[0025] When the decorative tail pipe of the automobile exhaust pipe of the present invention is connected to automobile exhaust pipes of different sizes, the length of the stud 4 screwed into the connecting pipe 1 can be adjusted, so that the carbon fiber arc plate 3 can be closely attached to the automobile exhaust pipe. , which is suitable for the installation of automob...

Embodiment 2

[0028] The preparation method of the surface treatment agent of the carbon fiber curved plate for the decorative tail pipe of the automobile exhaust pipe, firstly add 15 parts of hydroxy silicone oil, 25 parts of melamine formaldehyde resin and 10 parts of water into the container, heat to 40 ℃ and stir for 25 minutes; then slowly Add 6 parts of N-tert-butyl-2 benzothiazole sulfenamide, stir while adding, keep stirring at 40 °C for 25 minutes after the addition; then slowly add 15 parts of N,N-dimethylformamide and 10 parts of water , stir while adding, heat to 60 ℃ and stir for 25 minutes after adding; then slowly add 2 parts of protoveratrine, 10 parts of ethanol and 30 parts of water, heat to 80 ℃ and stir for 10 minutes to obtain the surface treatment agent.

Embodiment 3

[0030] The surface treatment method of carbon fiber arc plate for decorative tail pipe of automobile exhaust pipe, the steps are as follows:

[0031] ①. Use acetone to scrub the surface of the carbon fiber arc plate to remove oil stains, then dry the carbon fiber arc plate with a dry cloth, then scrub with ether, and finally dry it in a dust-free environment;

[0032] ②, put the carbon fiber arc plate into the surface treatment agent (prepared in Example 2) preheated to 60 ℃ and soak for 5 minutes;

[0033] 3. After taking out, rinse with 95% ethanol until the pH value is restored to neutrality, and then dry at 50°C for 6 hours;

[0034] ④. Spray a layer of 0.9μm thick polytetrafluoroethylene protective film on the surface of the carbon fiber arc plate.

Abstract

The invention provides a surface treatment method for a carbon fiber curved plate for a decorative tail pipe of an automobile exhaust pipe. The surface treatment method includes the following steps that firstly, the surface of the carbon fiber curved plate is scrubbed with acetone, oil stains are removed, then the carbon fiber curved plate is wiped and dried with dry cloth, and then the carbon fiber curved plate is scrubbed with ether and finally is air-dried in a dust-free environment; secondly, the carbon fiber curved plate is put into a surface treatment agent which is pre-heated to 60 DEG C and is soaked for 5 minutes; thirdly, the carbon fiber curved plate is washed with ethanol with the concentration being 95% till the pH valve returns to the neutral state after being fished out, and then the carbon fiber curved plate is dried for 6 hours at the temperature of 50 DEG C; and fourthly, the surface of the carbon fiber curved plate is coated with a layer of polytetrafluoroethylene protective film with the thickness being 0.9 micrometer. By the adoption of the surface treatment method, surface treatment of the carbon fiber curved plate can be achieved, both the hardness and the surface smoothness of the carbon fiber curved plate are improved remarkably, and the service life can be prolonged remarkably.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, in particular to a surface treatment method for a carbon fiber arc-shaped plate used for a decorative tail pipe of an automobile exhaust pipe. Background technique [0002] The tail pipes of the automobile exhaust system are divided into ordinary tail pipes and decorative tail pipes, which play the role of discharging the exhaust gas generated by the engine into the atmosphere. The decorative tail pipe can not only provide the function of the ordinary tail pipe but also play a decorative role. The decorative tail pipe of the existing automobile exhaust pipe has a complex structure and cannot be adapted to the installation of automobile exhaust pipes of different sizes. Therefore, it is necessary to provide a decorative tail pipe for an automobile exhaust pipe to solve the above problems. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invent...
