粘接密封剂是一种新型高分子材料。随着汽车工业的发展,对整车密封性质量的要求也在不断地提高。为此,在国外汽车制造业中,粘接密封工艺已成为定型工艺。其优越性是:简化结构,代替铆焊,防腐防漏,防震隔音,防锈密封等。国外密封工业所采用的粘接密封剂种类很多,每辆汽车需用胶量在10公斤以上。为增进中日友谊、交流解决我国汽车“三漏”的技术措施,在中国机械工程学会和汽车局的组织下,同日本“三键”公司进行了为期七天的技术座谈。本文仅就座谈中谈到的几种 Adhesive sealant is a new type of polymer materials. With the development of the automobile industry, the quality requirements of the vehicle sealing are also constantly increasing. To this end, in the foreign automobile manufacturing industry, adhesive sealing process has become a stereotyped process. Its advantages are: to simplify the structure, instead of Maohan, anti-corrosion leakage, earthquake noise, rust seals. Foreign sealing industry used in a wide range of adhesive sealants, each vehicle needs more than 10 kg of plastic. In order to promote the friendship between China and Japan and to exchange technical measures to solve the “three leaks” in China’s automobiles, a seven-day technical symposium was conducted with “three key” companies in Japan under the organization of China Mechanical Engineering Society and Automobile Administration. This article only talked about in the forum several
