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.
