COSCO leads the new trend of high-speed rail coating with partners

Gradual color coating process is the high-speed railway in China. The high-speed railway water-based coating market has a bright future. In recent years, the rapid development of China's high-speed railway technology has greatly changed people's travel and life style. The demand of different markets and lines at home and abroad also puts forward higher requirements for the coating of high-speed railway trains. In the published design scheme of Beijing Zhangjiakou high speed railway intelligent train, the special train named "Ruixue Yingchun" has brought a new visual experience of ice and snow crystal with its unique blue and white gradual change appearance design, which has attracted wide attention from all walks of life. The coating of the sample vehicle is made of the raw material of keschuang coating, which is jointly built by Sanhe Liangke Weize industrial coating Co., Ltd. and CRRC Changchun rail car Co., Ltd. (Changchun passenger Co., Ltd.). Gradient color, because of its rich color changes, has been favored by designers and widely used in various industrial designs. However, due to the high requirements of coating and coating process, gradient color is rarely used in the appearance design of high-speed rail trains.

The sample car adopts a unique color blending method and spraying process to achieve the effect of gradual color change. Thanks to the coating raw materials from Kesi Chuang, the coating effect is better in color performance, the coating has better weather resistance, UV resistance and longer gloss, which can ensure that the train still maintains a beautiful appearance after long-term operation. At the 2019 China International Coatings exhibition held in Shanghai New International Expo Center from November 18 to 20, keschuang (Booth No.: W2, B05) is showing the effect of gradual color coating and the latest high iron water-based coating solution of the sample vehicle. Water based coating has a broad market prospect. According to the national railway network planning, from 2021 to 2025, the national high-speed railway lines will grow from 30000 km to 38000 km, and the market demand for high-speed railway trains still has a huge space. At the same time, with its excellent performance and technical advantages, China's high-speed rail has become a "golden card" for China's infrastructure construction "going out", which needs to face higher coating requirements in different markets.

In addition, with the deepening of social awareness of environmental protection and sustainable development, the application of coatings, including in the field of rail transit, is rapidly changing to water-based environmental protection coatings. At present, high-speed rail trains are still mainly solvent coating. In addition to the breakthrough and innovation in the field of high-speed railway gradient coating, keschuang has been committed to providing water-based coating solutions for high-speed railway trains to meet the market demand. At present, kesico's water-based and easy to spray polyurethane coating series raw materials and solutions have been successfully applied to a number of urban rail, subway and other projects in the country, and began to work with partners in the field of rail transit coating such as liangkeweize to innovate and develop the high-speed rail market. The upgraded series of products and solutions of raw materials for water-based coating developed by kostron can better meet the requirements of long-distance and high-speed operation of high-speed railway.

The upgraded water-based high-speed rail coating solution has been applied to the water-based coating system of liangkeweize, which has the following characteristics: better weather resistance, chemical resistance and wear resistance: as part of the upgraded water-based high-speed rail coating solution, varnish is the protection of the outermost layer of high-speed rail train coating. Compared with the traditional rail transit coating, the upgraded product has better weather resistance, chemical resistance and wear resistance. Whether it is through sand belt or cleaning every day, it can ensure a beautiful appearance. Stronger adhesion, resistance to humidity, heat and water: high-speed trains shuttle between vast areas, often encountering high temperature and heavy rain. The upgrade coating scheme adopts two-component water-based primer, which has stronger adhesion than single component products, and has better resistance to damp heat and water. Even in high temperature and damp heat environment, the surface of the train remains intact. Better stone impact resistance: during high-speed operation, high-speed trains are easy to be impacted by small splashing stones, so the train surface coating needs to face severe test.

The two-component waterborne polyurethane primer in the upgraded coating scheme can further improve the flexibility and adhesion, which can help the surface coating of the train effectively resist the impact of flying stones. At present, the certification of the high-speed railway waterborne coating products cooperated by keschuang and liangkeweize has been basically completed. The two sides will promote further cooperation with the main engine plant and supporting plants of rail transit, and promote the application of waterborne coating on high-speed railway trains. In the future, the coating industry will change in the direction of water property. In the process of transformation, the upstream and downstream enterprises of the industry chain need to work closely together to accelerate product development, testing and application promotion. For this reason, kostron is working with companies such as liangkeweize to innovate, apply high-performance water-based coating solutions to a wider range of transportation fields, and improve the overall sustainable development of the transportation industry.
