Abstract

The invention discloses a spraying technique for a high-speed rail train body. The spraying technique comprises the following steps that pretreatment is conducted on the surface of the train body, and the to-be-painted surface of the surface of the train body is made clean and free of dust or rust or grease; prime paint is sprayed/painted on the surface of the train body in a rolling mode, the prime paint is white corundum sand, the roughness is made to reach 8-15 microns, and drying is conducted for 30 minutes; and intermediate coat paint is sprayed/painted onto the surface of the prime paint in a rolling mode, the intermediate coat paint is aliphatic polyurethane glass flake paint, drying is conducted for 0.5-1.5 hours, and then polyurethane glossy varnish is sprayed onto the intermediate coat paint three times. By the adoption of the spraying technique, the mechanical properties of the surface coatings of the high-speed rail train body are effectively improved.

Description

A kind of high-speed train vehicle body coating technique
Technical field
The present invention relates to field of track traffic, specifically a kind of high-speed train vehicle body coating technique.
Background technology
It is relatively big that the speed of existing high-speed train promotes degree, and original car group surface appearance effects and mechanical property requirements are higher, and original coating process is repeatedly to smear putty, there is putty thickness too high, surface bad mechanical property.Track traffic is after long-time operation, and its stripping paint phenomenon is serious, causes car body seriously to shorten service life.
Summary of the invention
It is desirable to provide a kind of high-speed train vehicle body coating technique, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of high-speed train vehicle body coating technique, it is characterised in that comprise the following steps:
Car body surface is carried out pretreatment, and the application face for the treatment of making car body surface is the most dustless, rustless, without oils and fats；
To car body surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；
At prime paint surface spraying/roller coating floating coat paint, described floating coat paint is aliphatic polyurethane glass flake paint, paints three times polyurethane coating varnishes of spraying at floating coat continuously after being dried 0.5-1.5 hour.
Further, the coating layer thickness of described prime paint is 100 μm-120 μm.
Further, the coating layer thickness of described floating coat paint is 130 μm-150 μm.
Further, the coating layer thickness of described polyurethane coating varnish is 130 μm-150 μm.
The beneficial effects of the present invention is: the present invention is compared with the coating system that way-train uses, mechanical performance and the glossiness of coating can be significantly improved, thus improve the wearability of coating, impact resistance and protect color gloss retention, the application needs of bullet train can be better adapted to.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
A kind of high-speed train vehicle body coating technique, it is characterised in that comprising the following steps: car body surface is carried out pretreatment, the application face for the treatment of making car body surface is the most dustless, rustless, without oils and fats；To car body surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；At prime paint surface spraying/roller coating floating coat paint, described floating coat paint is aliphatic polyurethane glass flake paint, paints three times polyurethane coating varnishes of spraying at floating coat continuously after being dried 0.5-1.5 hour.The coating layer thickness of described prime paint is 100 μm-120 μm.The coating layer thickness of described floating coat paint be the coating layer thickness of polyurethane coating varnish described in 130 μm-150 μm be 130 μm-150 μm.
The present invention, compared with the coating system that way-train uses, can significantly improve mechanical performance and the glossiness of coating, thus improves the wearability of coating, impact resistance and protect color gloss retention, can better adapt to the application needs of bullet train.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
