Current situation and application prospects of automotive adhesives
Adhesive is an indispensable raw material in automobile production. In automobile manufacturing, the use of good bonding technology can improve driving comfort, reduce noise, reduce vibration, lighten weight, reduce energy consumption, simplify processes, and improve product quality. Therefore, adhesives are used in vehicle design and manufacturing. To an irreplaceable role. According to the function, the application of adhesives in automobiles is mainly divided into car body glue, power system glue, and repair glue. Automotive adhesives play an important role in the quality and reliability of automobiles, the convenience of production processes, the provision of new solutions and the creation of new functions for automobiles.
Current situation of domestic and foreign automotive adhesive market
In 2016, the global automotive adhesives market was valued at 3.771 billion yuan, and is expected to reach 5.459 billion yuan by 2023, with a compound annual growth rate of 5.4%. Among them, polyurethane adhesives are the world's highest contributor to automotive adhesives, accounting for about 1/3 of the total. It was US$801 million in 2016 and is expected to reach US$1.225 billion by 2023, with a compound annual growth rate of 6.2% during the period.
In addition, according to a report released by the New Thinking Industry Research Center, in 2017, the global automotive structural rubber market reached 1.421 billion U.S. dollars, with actual production and sales of 539,000 tons. Among them, the size of my country's automotive structural adhesive market reached 241 million US dollars, accounting for 16.96% of the world. In the past two years, affected by the sluggish global automotive market, the growth rate of the global automotive structural rubber market has declined, but overall it will maintain a steady growth trend. With the progress of automotive lightweighting, automotive structural adhesives have become more widely used. It is estimated that the global automotive structural adhesive market will reach 1.639 billion US dollars in 2023, with a compound annual growth rate (CAGR) of 1.89%. It is estimated that by 2025, my country will reach 294 million US dollars (about 2 billion yuan).
Prospects for the application of automotive adhesives
Application prospects of adhesives in lightweight car bodies
Lightweight car body is a major trend in the development of the automobile industry and a key development direction for reducing fuel consumption and carbon dioxide emissions in the future. In addition to fuel saving and environmental protection, it also provides weight space for the installation of more electronic and other functional devices in the car. However, the introduction of lightweight materials for automobiles and the lightweight design of the body structure will bring a series of challenges to the traditional automobile manufacturing process. For example, the thinning of the sheet thickness may cause the body rigidity and local structural strength to decrease, which will cause the body collision safety and Problems such as structural vibration and noise are generated, and the use of bonding technology and local reinforcement technology is an effective way to solve these problems.
With the trend of automobile lightweight and the accelerated development of new energy vehicles, the automobile industry has become the largest adhesive application field after construction and light industry, covering almost all types of adhesives, and the application range is becoming wider and wider. Also getting higher. There are more than 3,000 large and small companies related to automotive adhesives in the country. According to the assumption that the amount of adhesive used in bicycles is 20-40KG, the market size of adhesives for the automotive industry in my country has exceeded 500,000 tons per year, and it has become the world's largest automotive adhesive application. country.
Although the current automotive adhesive market is still dominated by foreign companies headed by Henkel, localization is the general trend. It is believed that Chinese national adhesive companies will gradually realize import substitution in China's automotive adhesive industry.
