The invention provides a production method of a high-temperature-resistant sound-insulation composite board, belonging to the field of composite boards. The high-temperature-resistant sound-insulationcomposite board comprises the following steps: preparing butyl rubber by using a sludge method; conducting mulling and calendering to form a butyl rubber board with a groove on one side; and compounding aluminum plates and butyl rubber in a vacuum environment in a vacuum compounding machine. According to the invention, the aluminum plates and the butyl rubber are tightly combined by adopting a mode of compounding the aluminum plate and the butyl rubber in a production stage; meanwhile, in order to prevent the aluminum plate in the compounded composite board from being corroded in the vulcanization step of the butyl rubber, two layers of aluminum plates are arranged between two layers of butyl rubber by adopting a double-layer compounding mode; and thus, the bonding performance of the aluminum plates and butyl rubber is improved, and meanwhile the aluminum plates are prevented from being corroded.
本发明提供一种耐高温隔音复合板的生产方法,涉及复合板领域,包括采用淤泥法制备丁基橡胶、混练、压延形成一侧带有凹槽的丁基橡胶板,在真空复合机中将铝板与丁基橡胶在真空环境下复合,采用采用铝板与丁基橡胶在生产阶段复合的方式,使铝板与丁基橡胶紧密结合,同时为避免复合后的复合板材中铝板在丁基橡胶的硫化步骤中被腐蚀,采用双层复合的方式,将两层铝板置于两层丁基橡胶之间,在提高铝板与丁基橡胶的结合性能同时,避免铝板被腐蚀。
