Experts talk about the development and promotion of water-based automotive paint

There are many ways of environmental protection of coatings, and the development of water-based coatings is one of the effective means. At the appraisal meeting for scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation, industry experts highly praised Yulin's research on waterborne two-component acrylic polyurethane passenger car paint products and construction methods. The field of automotive coatings has played a pioneering role.

Highlights: Waterborne + Scale

(Qian Borong, Professor Level Senior Engineer, CNOOC Changzhou Paint & Chemical Institute)

Qian Borong, professor-level senior engineer at CNOOC Changzhou Institute of Coatings and Chemicals, said that many companies, universities, and research institutes in China are currently engaged in research on water-based coatings, but it is rare to achieve large-scale production. He believes that the successful development and large-scale production of Yulin's water-based automotive paint will provide important inspiration and promotion for the environmental protection of coatings in China.

Zhao Quansheng, a professor-level senior engineer at the Tianjin Chemical Society, pointed out that traditional solvent-based paints have organic solvents such as benzene, toluene, and xylene, which are extremely harmful to the environment, especially to workers. Yulin Company has conducted systematic research and development work on waterborne automotive coating technologies. It has pioneered the use of acrylic polyurethane as a resin material. It has achieved complete water-based priming, middle lacquer, and topcoat, and VOC content has been greatly reduced and improved. The coating operation environment has important practical significance for environmental protection.

(Song Anning Senior Engineer, China Environmental Protection Industry Association)

Song Anning, senior engineer of the China Environmental Protection Industry Association, believes that Yulin's water-based automotive paint meets the requirements of the national environmental protection industry policy. It is of great significance to the clean production and environmental protection of the paint industry, and greatly reduces the pressure on the processing of the tail. Benefits and environmental benefits. He suggested that Yulin Company declare the technological innovation of state-owned SMEs and strive for state financial support.

Advantages: Specialization and refinement

(Liu Dengliang, Director of Expert Committee of China National Coatings Industry Association, Professor-level Senior Engineer)

Liu Dengliang, director of the expert committee of the China Coatings Industry Association and a senior engineer at the professor level, introduced that he had visited many companies in the domestic paint industry, including some of the industry's leading large and medium-sized paint manufacturers, but was able to develop waterborne automotive coatings like Yulin. The companies are rare. It is precisely because of their specialization and refinement that they give full play to their own advantages that this little-known private enterprise can achieve a major breakthrough in this difficult topic of waterborne automotive coatings. It should be said that Yulin has made a meaningful and pioneering work in the field of domestic waterborne coatings.

Zhao Quansheng, a professor-level senior engineer at the Tianjin Chemical Society, believes that Yulin’s water-based two-component automotive paints have achieved a complete range of primers, middle paints and top coats. The most difficult thing is that the topcoat technology is under the premise of ensuring conventional performance. High-gloss, high-brightness coating effects are achieved, and the requirements for temperature and humidity in the construction environment are broadened, which has important practical significance for the promotion of water-based paints by domestic and foreign bus manufacturers.

(Zhao Ling Senior Engineer, National Coating Quality Supervision and Inspection Center)

Zhao Ling, a senior engineer of the National Coatings Quality Supervision and Inspection Center, analyzed the results of the tests and concluded that Yulin's waterborne automotive paints have reached a relatively high level of performance, especially with a significant reduction in volatile organic compounds (VOC) content. In view of the fact that China still does not have national standards and industry standards for waterborne automotive coatings, she recommends that Yulin further improve the testing of the performance of waterborne automotive paint products, so as to provide more theories for the formulation of national standards and industry standards for waterborne automotive coatings in the future. Based on practice, and strive to participate in the formulation of standards.

(Liu Jianying, Professor, Senior Engineer, Tianjin Lighthouse Paint Company)

Yulin's painting construction site gave a deep impression to Professor Liu Jianying, a professor-level senior engineer at Tianjin Lighthouse Paint Company. She thinks Yulin has solved a lot of details of the technology and process. For example, by adjusting the curing agent to prevent blistering of the paint surface and verifying it in the spraying process, Yulin also achieved complete water-based use without using a solvent-based paint. In addition, for the difficulty of coating adhesion on plastic parts, Yulin conducted relevant test work for FRP, PP, PE and other substrates and achieved certain progress. She said that from the effect of the painting construction site, based on the realization of complete water-based, the overall effect of the car finish has met the requirements of the bus spray. Perfect coating construction technology plays an important role in achieving the coating effect. She proposes to further expand the development and application of waterborne resins and improve product performance.

Direction: Industrialization + Marketization

(Jiang Yan China Paint Industry Association vice chairman)

For Yulin, the successful development of water-based automotive paint was just the first step in the long march. How new products win the market is the next key issue to consider. In this regard, the vice president of the China Coatings Industry Association, Professor Changyi Chang, believes that on the one hand, it is necessary to reduce costs and increase product market competitiveness through localization of raw materials and mass production; on the other hand, training can be used to promote the application of water-based automotive paints. Technology and process to accelerate the marketization of the product. In addition, she also encourages Yulin to cooperate with research institutes at home and abroad to conduct cooperation in production, learning and research, accelerate the industrialization of scientific and technological achievements, and promote the technical progress of waterborne automotive coatings.

Under normal circumstances, paint manufacturing companies pay more attention to the development and production of coatings, and neglect coating construction. Qian Borong, professor-level senior engineer at CNOOC Changzhou Institute of Coatings and Chemicals, believes that Yulin is a company with a coating background. It has great advantages in researching and developing coatings, and can study technical details from the perspective of construction technology. In particular, there are various substrate materials. If coating companies cannot accurately grasp the coating process, it is difficult to produce high-quality coating products.

(He Lifan Senior Engineer, Beijing University of Chemical Technology)

He Lifan, a senior engineer at Beijing University of Chemical Technology, also stated that the paint is only a semi-finished product and that it will require professional painting to realize its value. Having a group of high-quality and high-level paint construction workers is the key to realizing the coating effect of paint products. He proposed that Yulin Company should perfect the painting process on the basis of the existing bus and bus market and move forward to the car market.
