橡胶湿式摩擦件历来都是将碳精橡胶、软木橡胶或钢丝绒橡胶等装在铁芯上,并开出油槽。此类摩擦件只能通过油槽给油或排油,易引起断油和刹车噪声。 本发明为克服上述缺陷,采用橡胶基材,掺入特制的纸屑,成型后装在铁芯上,即制成无噪声、含纸质橡胶类的湿式摩擦件。 实施例(配料均为重量份):硅酮橡胶:100三氟化树脂:40硅质纤维:80 Rubber wet friction pieces have always been carbon rubber, cork rubber or steel wool rubber installed on the core, and out of the tank. Such friction pieces only through the tank to the oil or oil discharge, easy to cause oil and brake noise. In order to overcome the above defects, the present invention adopts a rubber substrate and incorporates a special paper scraps, which is then loaded on the iron core after molding to obtain a wet friction material containing no noise and paper rubbers. Examples (ingredients are parts by weight): Silicone rubber: 100 Trifluororesin: 40 Silicone fibers: 80
