preparation example 1

[0045] Preparation example 1: The raw material ratio of modified aramid fibers is shown in Table 1. 1.6 kg of aramid fibers are wound on a cylindrical glass frame, and the glass frame is ultrasonically cleaned in 10 kg of acetone solution with a mass fraction of 10%. After drying for 1 hour, soak the aramid fiber in 16 kg of phosphoric acid solution with a mass fraction of 24%, and heat it to 30°C. Brush the mixed solution of 5 kg of modified epoxy resin activation solution and 15 kg of resorcinol-formaldehyde resin solution with a mass fraction of 15% on the aramid fiber, then put the aramid fiber at 3.8KPa, and dry it at 90°C for 4h .

preparation example 2

[0046] Preparation example 2: The raw material ratio of modified aramid fibers is shown in Table 1. 2.0 kg of aramid fibers are wound on a cylindrical glass frame, and the glass frame is ultrasonically cleaned in 15 kg of acetone solution with a mass fraction of 13%. After drying for 1.5 hours, soak the aramid fiber in 18 kg of phosphoric acid solution with a mass fraction of 26%, and heat it to 35°C. Brush the mixed solution of 7 kg of modified epoxy resin activation solution and 17 kg of resorcinol-formaldehyde resin solution with a mass fraction of 18% on the aramid fiber, then put the aramid fiber at 4.0KPa, and dry it at 95°C for 4.5 h.

preparation example 3

[0047] Preparation Example 3: The ratio of raw materials for modified aramid fibers is shown in Table 1. 2.4 kg of aramid fibers are wound on a cylindrical glass frame, and the glass frame is ultrasonically cleaned in 20 kg of acetone solution with a mass fraction of 15%. Dry after 2 hours, soak the aramid fiber in 20 kg of phosphoric acid solution with a mass fraction of 28%, and heat it to 40°C, keep it warm for 1 hour, take it out, wash it repeatedly with 40 kg of distilled water until neutral, Brush the mixed solution of 9 kg of modified epoxy resin activation solution and 18 kg of resorcinol-formaldehyde resin solution with a mass fraction of 15% on the aramid fiber, then dry the aramid fiber at 4.2KPa at 100°C for 5 hours .

Abstract

The invention discloses a motorbike hydraulic disc brake non-asbestos lining and a preparation method thereof. The motorbike hydraulic disc brake non-asbestos lining comprises the following componentsof, by weight, 8-12 parts of copper fiber, 18-22 parts of modified phenolic resin, 4-8 parts of butyronitrile powder, 5.5-10.5 parts of modified aramid fiber, 6-10 parts of potassium titanate whisker, 5-9 parts of aluminum fiber, 10-16 parts of natural graphite powder, 4-8 parts of friction powder, 4-10 parts of filler, 6-10 parts of titanium carbide, 20-24 parts of rock wool, 5-10 parts of a lubricating agent and 4-9 parts of an abrasive material. The preparation method of the motorbike hydraulic disc brake non-asbestos lining comprises the steps of S1, raw material mixing, S2, pre-pressingforming, S3, steel backing preparation, S4, hog pressing forming, S5, heat treatment, and S6 grinding and drilling. The motorbike hydraulic disc brake non-asbestos lining has the advantages of being good in heat resistance, stable in high-temperature friction coefficient, and good in heat fading performance. The preparation method has the advantages of being simple and convenient and high in preparing accuracy.

Description

technical field [0001] The invention relates to the technical field of friction materials, more specifically, it relates to a non-asbestos lining for hydraulic disc brakes for motorcycles and a preparation method thereof Background technique [0002] Friction material is a multi-component composite material used for braking and transmission of vehicles and power machinery. Its quality directly affects the reliability of the machine and the life safety of the operator. Friction materials mainly include brake linings (commonly known as brake pads) and clutch facings (commonly known as clutch plates). Brake pads are used for braking and clutch plates are used for transmission. [0003] In the history of the application of friction materials, asbestos friction materials with asbestos fibers as reinforcement materials can meet the requirements of friction materials due to their main raw material, asbestos fibers, which have a series of advantages such as good heat resistance and...
