一种盘式刹车片的制备方法
摘要：
本发明涉及一种盘式刹车片的材料配方。所使用的材料按如下重量百分比组成：粘合剂5-10、增强材料20-30、研磨剂10-20、润滑剂15-25、填料30-50。其中的粘合剂包括酚醛树脂、丁腈改性酚醛树脂、硅改性酚醛树脂的一种或两种组合；增强材料包括钢棉纤维、芳纶浆粕或陶瓷纤维、芳纶浆粕的组合；研磨剂包括氧化铁、氧化镁、三氧化二铝、摩擦粉的组合；润滑剂包括无机润滑剂与金属硫化物组合，或有机润滑剂与金属硫化物组合；填料是硫酸钡、碳酸钙、氧化镁的组合。本发明生产的刹车片时，能够在摩擦界面形成一种润滑膜，消除现有摩擦材料在摩擦过程中表面形成的硬质点，消除了低频噪音发生的机率，使低频噪音的发生率降低在10％以下。
摘要（英）：

This invention relates to the formulation of a disk-type brake material, which is composed of: adhesive 5-10 wt.%, reinforcing material 20-30 wt.%, grinding agent 30-50 wt.%, lubricating agent 10-20 wt.%, and filler 20-30 wt.%. The adhesive is one or two of phenol formaldehyde resin, nitrile-modified phenol formaldehyde resin and Si-modified phenol formaldehyde resin. The reinforcing material is a composition of steel cotton fibers and aramid pulp or a composition of ceramic fibers and aramid pulp. The grinding agent is a composition of Fe2O3, MgO, and Al2O3 and friction powder. The lubricating agent is a composition of inorganic lubricating agent and metal sulfide or a composition of organic lubricating agent and metal sulfide. The filler is a composition of BaSO4, CaCO3 and MgO. The brake can form a layer of lubricating film on the friction interface, thus can eliminate hard particles on the surface and occurring probability of low-frequency noise and decrease low-frequency noise tobelow 10%.
