Brake block friction material granulating manufacturing process

Abstract

The invention relates to a brake disk friction material granulation technology. It adds 2.9 portions honey into 100 weight portions mixed brake disk friction material and adds 10 weight portions water in one minute, whisking for 4 minutes to take granulation, putting the grained particle into oven for drying 1 hour under 120 degree centigrade to make the water content below 1%. The diameter of the particle is 1.5-3mm, and the weight is 102.9 portions. The advantage of the invention is that it has simple technology, good dispersibility, environment protection, etc.

Description

Technical field: [0001] The invention relates to the technical field of friction material granulation technology, in particular to a brake pad friction material granulation manufacturing process. Background technique: [0002] At present, the granulating agent used in the granulation process of friction materials is mostly an imported granulating agent, its model is "BONDING AGENT FMT NET 222603", which is a kind of chemical cellulose fiber, which is easy to form gel when it meets water, and has poor dispersibility. The granulation process is complicated and the price is relatively high (about 17-18 yuan per kilogram). The disadvantages of its process are as follows: 1. It must be mixed with water first, and then stirred at a high speed for a long time (about 75 minutes) at a certain temperature (about 60°C), and then stirred for 10 minutes after mixing in friction materials; 2. Even if the above-mentioned process is adopted, in the produced granules, gel aggregation phenom...

[0002] At present, the granulating agent used in the granulation process of friction materials is mostly an imported granulating agent, its model is "BONDING AGENT FMT NET 222603", which is a kind of chemical cellulose fiber, which is easy to form gel when it meets water, and has poor dispersibility. The granulation process is complex and the price is relatively high (about 17-18 yuan per kilogram)

The disadvantages of its process are as follows: 1. It must be mixed with water first, and then stirred at a high speed for a long time (about 75 minutes) at a certain temperature (about 60°C), and then stirred for 10 minutes after being mixed with friction materials; 2. Even if the above process is adopted, there are still gel aggregation phenomena in about 5% of the produced granules; 3. Due to the appearance of the gel phenomenon, the baking time is increased by 25%
