Low-noise and anti-rust-adhesion drum brake pad for new energy vehicle and preparation method thereof

The invention belongs to the technical field of vehicle brake pads, and particularly relates to a low-noise and anti-rust-adhesion drum brake pad for a new energy vehicle. The low-noise and anti-rust-adhesion drum brake pad comprises the following raw material components in percentage by weight: 10-15% of mineral fiber, 5-10% of calcium hydroxide, 5-10% of calcium oxide, 3-5% of zinc powder, 5-20% of calcium sulfate whisker, 2-5% of friction powder, 5-10% of high-aluminum vanadine, 2-5% of polyacrylonitrile fiber, 5-10% of glass fiber, 5-15% of synthetic graphite, 10-15% of resin, 3-8% of rubber, and the balance of barite. The formula does not contain rusty metal such as iron, and the calcium hydroxide and the calcium oxide are added, so that the pH value of the brake pad is increased, and the brake pad has a good anti-rust effect. The zinc powder is added, so that the heat conductivity coefficient of a friction material is increased, decomposition of organic matter is relieved, heat fading of the friction ma
