The invention provides an automobile stripe silencing sheet and a preparation process, and relates to the technical field of silencing sheet production. The preparation process comprises the following steps: S1, coating one side of a metal plate base material with a rubber solution, and forming a rubber layer overlapped with the metal plate base material, wherein the rubber layer and the metal plate base material are matched with each other to form a metal composite plate; s2, vulcanizing the metal composite plate to obtain a vulcanized metal composite plate; and S3, roll coating, brush coating or dip-coating a graphite-based resin coating on the vulcanized metal composite plate, and arranging the graphite-based resin coating on the rubber layer in a striped manner to obtain the anti-scratching layer. According to the preparation process, the striped graphite-based resin coating can be processed on the rubber layer,so that the prepared silencing sheet has an anti-scratching effect, the metal composite plates are prevented from being stacked together in the product stamping process, burrs on the edges of a friction product are prevented from scratching the surface of the product in the packaging process, and the final forming quality of the product is improved. The silencing sheet is prepared by the process and has all the beneficial effects.
本发明提出了一种汽车条纹消音片及制备工艺,涉及消音片生产技术领域。该制备工艺包括以下步骤:S1,在金属板基材一侧涂覆橡胶溶液,形成和金属板基材相互叠合的橡胶层,橡胶层和金属板基材相互配合形成金属复合板;S2,对金属复合板进行硫化,得到硫化后金属复合板;S3,在硫化后金属复合板上滚涂、刷涂或浸涂石墨基树脂涂层,将石墨基树脂涂层以条纹状设置于橡胶层上,得到防划层。该制备工艺能够通过在橡胶层上加工出条纹状的石墨基树脂涂层,使得制备出的消音片具有抗划伤作用,避免金属复合板在冲压产品过程中有叠重在一起及包装时产生磨擦产品边上毛刺划伤产品表面,提高产品最终的成型质量。该消音片由上述工艺制备而成,具有其所有有益效果。
