Processing technology of licence plate blank not prone to paint shedding

Abstract

The invention relates to a processing technology of a licence plate blank not prone to paint shedding. The processing technology comprises the following steps of 1, trimming an aluminum material to form an aluminum base plate, and then utilizing a punching machine for punching; 2, treating the surface of the aluminum base plate; 3, brushing priming paint on the surface of the aluminum base plate,and afterwards, conducting drying and sizing; 4, pasting reflective film on the surface of the aluminum base plate, and conducting corona treatment; 5, coating the reflective film after corona treatment with a cracking-resisting and wear-resisting priming paint, and afterwards, conducting drying and sizing; 6, printing oil paint on cracking-resisting and wear-resisting priming paint through a screen printing machine, and afterwards conducting drying; 7, coating the surface of the formed oil paint with transparent wear-resisting paint, and afterwards conducting drying and sizing; and 8, coatingthe wear-resisting paint with an anti-fouling coating, and afterwards conducting drying and sizing to form the licence plate blank. By means of the processing technology, through coating of the cracking-resisting and wear-resisting priming paint and the transparent wear-resisting paint, the wear resistance of a licence plate is improved, and the probability that the oil paint cracks or sheds is lowered.

Description

technical field [0001] The invention relates to a processing technology of a license plate body which is not easy to peel off the paint. Background technique [0002] The license plate refers to the vehicle license plate. The license plate is a plate that is hung on the front and back of the car on both sides. It is usually made of aluminum, plastic or stickers. The registration number, registration area or other basic information of the car will be displayed on the plate. The license plate is the serial number of the car, and its main function is to know the province, city and county to which the car belongs. [0003] The production method of the license plate in the prior art has many residues on the substrate cleaning surface, uneven paint layer thickness on the substrate surface, uneven paint film, etc., and defects such as flow marks, wrinkles or bubbles are prone to occur, and these defects are in the process of the license plate. After a long time of use, the paint l...

Problems solved by technology

[0003] The production method of the license plate in the prior art has many residues on the substrate cleaning surface, uneven paint layer thickness on the substrate surface, uneven paint film, etc., and defects such as flow marks, wrinkles or bubbles are prone to occur, and these defects are in the process of the license plate. After a long time of use, the paint layer is easy to fall off, the characters are cloudy, and it is difficult to identify; and the traditional motor vehicle license plate is generally formed by stamping aluminum alloy, and the surface of the license plate is sprayed with reflective paint for concave and convex characters. It is easy to cause cracking of the paint surface and affect the quality of the license plate
