Oil paint coating method for external identifier of metro vehicle

Abstract

The invention discloses an oil paint coating method for an external identifier of a metro vehicle, which comprises the steps of blending oil paint and a curing agent according to a certain volume ratio; manufacturing a silk-screen template according to the content of the identifier, and fixing the silk-screen template at an external corresponding region of the vehicle; coating the blended oil paint on the silk-screen template, and performing the blade coating by a scratch board; and removing the silk-screen template, and drying the identifier under a room temperature. Due to the oil paint coating method, the external identifier of the metro vehicle is good in weather resistance, ultraviolet ray resistance, aging resistance and the like, so that the use durability of the external identifier of the metro vehicle can be guaranteed, the aging, the fading and the falling of the external identifier of the metro vehicle through wind blowing, raining and solarizing and the cleaning of vehiclecleaning liquid caused by lamination can be completely eradicated, the passenger safety can be guaranteed, and the metro vehicle can be conveniently overhauled. Meanwhile, due to the oil paint coating method of the external identifier of the metro vehicle, the quality of the metro vehicle is greatly improved.

Description

technical field [0001] The invention relates to a coating method, in particular to an easy-to-implement method for coating some complicated and small marks on the exterior of a subway vehicle. Background technique [0002] With the rapid development of urban subway traffic, the demand for subway vehicles is also further expanding. For the safety of passengers and the convenience of subway vehicle maintenance, subway vehicle manufacturers have many warning signs on the outside of subway vehicles. In the past, the exterior signs of subway vehicles were made of film, but after a long time, after being exposed to wind, rain, sun and car wash, the exterior film tends to age, fade or even fall off, which seriously affects the safety of passengers and brings serious problems to the maintenance of subway vehicles. Great inconvenience. [0003] At the same time, most of the paints used in the interior and exterior of existing subway vehicles are two-component paints, that is, curin...

Problems solved by technology

In the prior art, operators use glass measuring cups to measure the paint. If too much paint is measured, the measuring cup will easily slip and break, which will injure the on-site operators, and using the measuring cup to measure the paint will cause the viscosity of the paint to be high. Part of the paint will remain on the measuring cup, resulting in inaccurate measurement of the paint volume, resulting in incorrect proportioning and affecting the performance of the paint film

In addition, cleaning the measuring cup wastes the amount of thinner, brush, white cloth and other consumable materials, and the operation is inconvenient and the efficiency is extremely low

[0004] These problems have been reflected in several previous subway projects, which cannot meet the 15-year service life required in the subway vehicle contract and need to be resolved urgently
