Problems solved by technology

The friction surface of the traditional disc brake pad is not processed by brush coating, and the finished product is directly loaded and used, but there are the following defects and deficiencies: 1. Traditional disc brake pad: there is no coating process on the friction surface, and the product is installed After the car is put on the car, it takes a long time to run in before the friction coefficient can be stable; 2. At the beginning of loading, the contact area between the brake pad and the brake disc is small, the braking torque is small, the braking distance is long, and the safety is poor; 3. The grinding surface There are appearance defects such as tiny pits and grinding scratches, which affect the appearance quality and performance of the product

Embodiment 1

[0039] A brush coating on the friction surface of a disc brake pad and its production process. The raw materials of the coating include phenolic resin, iron oxide black and aluminum oxide, and the mass percentages are 200:1:100.5 in sequence;

[0040] The production process of the coating is:

[0041] Step 1: Preparation of black glue

[0042] (1) The black glue solution is prepared from PR-55735 phenolic resin and iron oxide black, and the raw materials are prepared according to the ratio (mass percentage) of phenolic resin:iron oxide black=200:1;

[0043] (2) Sprinkle iron oxide black slowly and evenly into the container filled with phenolic resin, and stir for 15 minutes until iron oxide black is fully dissolved;

[0044] (3) After the preparation is completed, the barrel is sealed and sealed for use;

[0045] Step 2: Preparation of coating solution

[0046] (1) The coating liquid is prepared from the black glue solution and alumina in step 1, and prepares raw materials ...

Abstract

The invention relates to a disc type brake pad friction surface coating layer, and a production method thereof, and belongs to the technical field of disc type brake pad manufacturing. The disc type brake pad friction surface coating layer is composed of phenolic resin, iron oxide black, and aluminium oxide at a mass ratio of 200:1:100.5. The production method comprises following steps: 1, preparation of a black rubber solution; 2, preparation of a coating solution; 3, coating of the coating solution; and 4, drying. The production method is capable of realizing brake pad surface coating, increasing product initial friction coefficient, and maintaining brake stability; surface coating layer wearing is rapid, the run-in period of the brake pad with a brake disc is shortened, contact area islarge, braking torque is large, braking distance is short, braking safety is improved; appearance defects such as friction surface small pits and grinding scratches are eliminated, product appearancequality and performance are improved, and market share is increased; and the friction surface coating layer technology is suitable for manufacturing of OE high end market products.

Description

technical field [0001] The invention relates to a brush coating on the friction surface of a disc brake pad and a production process, belonging to the technical field of disc brake pad manufacturing. Background technique [0002] The disc brake pad is an important component of the brake system, which is fixed with the tire of the vehicle and cooperates with the caliper to brake the vehicle. The friction surface of the traditional disc brake pad is not processed by brush coating, and the finished product is directly loaded and used, but there are the following defects and deficiencies: 1. Traditional disc brake pad: there is no coating process on the friction surface, and the product is installed After the car is put on the car, it takes a long time to run in before the friction coefficient can be stable; 2. At the beginning of loading, the contact area between the brake pad and the brake disc is small, the braking torque is small, the braking distance is long, and the safety...
