Adhesive Development history and current situation of my country's automotive adhesive sealant industry!

Jun 05, 2020

Although automobile adhesives and sealants are only auxiliary process materials in the automobile manufacturing process, the application of such materials can simplify the automobile production process, save the amount of materials used, and increase the strength of the parts, especially in shock, heat, corrosion, and rust , It has a special role in anti-loosening, anti-leakage, reducing noise, reducing self-weight, improving the comfort and safety of cars, etc. Adhesive sealant has become an indispensable process material in the production of modern automobile industry.

Mid-twentieth century: With the completion of a major domestic automobile manufacturing plant in Changchun, Jilin Province, my country's automobile industry has entered the era of the automobile manufacturing industry starting from trucks. Because the design of the Soviet Union was followed at that time, the technology was relatively backward, and the application of new materials was almost blank. The application of adhesive sealing technology in automobiles is at a very low level, which is manifested in fewer types, less dosage and low technical content.

Before the mid-1980s: There are only a handful of adhesive sealants used in the automotive industry. The use of these low-tech rubber types can neither guarantee the quality of automotive products, but also bring harm to the environment and the human body. The body welding has no design requirements for adhesives and no adhesive sealant varieties.

In the mid-to-late 1980s: my country's auto industry has successively imported nearly 70 vehicle and key component manufacturing technologies from abroad, and the auto industry has experienced vigorous development. At the same time, it also promotes the development of my country's automotive adhesive sealant industry. In 1988, Oriental Motor Company introduced Nissan body production technology, involving more than 10 new varieties of adhesive sealants that have not been used in China. Dongfeng Motor Co., Ltd. and Xiangfan 42 Research Institute of the Aerospace Department of the Beijing Institute of Aeronautical Materials have cooperated to realize the localization of the adhesive sealant needed for the imported models to meet the production needs of new models. In the same period, the models introduced by Shanghai Volkswagen, FAW-Volkswagen, Tianjin Xiali, Beijing Cherokee, Nanqi Iveco, etc., also put forward development and application requirements for automotive adhesives. During this period, the development and application of automotive adhesive sealant products in my country began to enter a rapid growth period.
