Embodiment Construction
[0019] attached figure 1 It is a schematic diagram of the steps of the preparation method of the anti-rust adhesion automobile brake lining of the present invention. It can be seen from the figure that the components of the anti-rust adhesion automobile brake lining of the present invention are generally used in semi-metal / less metal friction materials or asbestos organic type NAO friction materials. Add 3% to 10% by weight of anti-blocking additive to the base formula of the granule; the weight ratio of the anti-blocking additive is composed of: 10-20 parts of mineral fibers, 20-30 parts of zinc powder, and 30-50 parts of calcium hydroxide. parts, 10-15 parts of potassium titanate, 10-20 parts of friction powder and 20-30 parts of magnesium oxide; the addition amount of the anti-blocking additive is 3%-10% by weight.
[0020] Preferably, the mineral fiber in the rust-adhesive automobile brake lining component of the present invention is a surface-modified aluminum silicate fi...

Abstract
The invention provides a rust adhesion-proof automobile brake lining component and an automobile brake lining preparation method. In a matrix formula of a commonly used semi-metal / less-metal friction material or an asbestos organic matter type NAO friction material, an adhesion-proof additive with the weight percentage of 3 percent to 10 percent is added; the adhesion-proof additive is prepared from the following materials in parts by weight: 10 to 20 parts of mineral fibre, 20 to 30 parts of zinc powder, 30 to 50 parts of calcium hydroxide, 10 to 15 parts of potassium titanate, 10 to 20 parts of frictional powder and 20 to 30 parts of magnesium oxide; the addition amount of the adhesion-proof additive is the weight percentage of 3 percent to 10 percent. The rust adhesion-proof automobile brake lining component and the automobile brake lining preparation method have the beneficial technical effects of effectively reducing or eliminating a phenomenon that a brake lining easily generates rust adhesion with a brake disc / drum under the premise of ensuring the braking performance of the brake lining to completely meet relative standard requirements.
Description
[0001] Field of Invention [0002] The invention relates to the preparation technology of automobile brake linings, in particular to a rust-proof adhesion automobile brake lining component and a preparation method of the automobile brake linings. Background technique [0003] At present, the parking function of passenger cars is completed by the rear brake of the car. According to the form of the brake parking mechanism, it can be divided into: 1. The leader-slave drum brake. 2. In-disk drum brake. 3. Disc integrated integrated parking brake. 4. Disc electronic parking brake. When parking the above-mentioned brakes, a parking force is applied to the brake lining, so that the brake lining and the dual surface (brake drum or brake disc) are closely attached to prevent relative sliding to realize the parking function. The dual material of these brakes currently used in most passenger cars is mostly cast iron. Cast iron rusts easily in water and humid air. At present, the ma...
