Embodiment 1

[0007] Example 1, the weight parts of various raw materials in the batching process are respectively, phenolic resin 10, aramid short fiber 5, ceramic fiber 10, copper fiber 5, zircon 4, iron black 2, graphite 5, friction powder 3, sulfuric acid Barium 20, potassium titanate 15, tire powder 2, grinding material 10. The above-mentioned raw materials are recycled on the existing processing production line-material mixing-cold molding-vulcanization-grinding-inspection, and finally packaged to obtain the finished car brake pad.

[0008] The brake pad prepared by the technical method of the present invention is qualified in performance through the klass bench QC / T582-1999 standard test; the shear strength is 4.5MPa (standard ≥ 4.0MPa).

Abstract

The invention relates to a preparation technique field of brake block of a car, in particular to a method for using grinding waste to prepare buoyant material of the brake block of the car. The technical proposal is as follows: the preparation of resin, fiber, a grind-enhancing agent, a grind-reducing agent, a friction modifier and a filling agent is carried out by the following technique steps of: blenching, mixing, cold forming type, vulcanization, grinding and inspection, wherein, the grind-reducing is graphite and the friction modifier is frictional powder. The resin adopts phenolic resin, the fiber adopts that aramid short fiber, ceramic fiber and copper fiber are mixed, the grind-enhancing agent adopts that zircon and iron black are mixed, the filling agent adopts that barium sulfate, potassium titanate, grinding material and tire powder are mixed. The invention uses the existing technique to prepare the buoyant material of the brake block of the car by adding the grinding waste material so as to reduce the cost. By using the product processed by the materials, the shearing strength meets the requirements, the friction performance also meets requirements and the cost is reduced.

Description

technical field [0001] The invention relates to the field of preparation technology of car brake pads, in particular to a method for manufacturing car brake pad floating material by using grinding waste. Background technique [0002] At present, the commonly used processing technology of car brake pads is: batching - mixing - cold forming - vulcanization - grinding - inspection - packaging. The powder material produced after the product is ground is treated as waste material for scrapping. One is to cause environmental pollution, and the other is to waste resources. Contents of the invention [0003] The purpose of the present invention is to solve the aforementioned problems caused by the inability to effectively utilize a large amount of waste materials produced after grinding in the existing production process of brake pads. A method for sheet floating material. [0004] The technical solution is: resin, fiber, grinding agent, friction reducing agent, friction modifi...
