Embodiment 1
[0024] Using high-silicon iron tailings with a median diameter of 12.21 μm and a mass content of 10% (the mass content of silicon dioxide is 78%, and the mass content of iron oxide is 18%, the same below) as one of the raw materials, and then mixed with Add 18% phenolic resin, 18% styrene-butadiene rubber, 0.9% zinc stearate, 10.8% carbon black (it has exceeded the maximum content in the formula, please modify), 27.9% barium sulfate, 14.4% long Stone powder is used as raw material, and high-silicon iron-doped tailings resin-based friction material is made by blending and dry hot-pressing process. When the friction and wear test is carried out at 350°C (using the method of the national standard GB / T 5764-1998, the following Same), friction coefficient (μ) and wear rate (V) are 0.48 and 0.68×10 -7 cm 3 / (N·m).
Embodiment 2
[0026] Using high-silicon iron tailings with a median diameter of 5.23 μm and a mass content of 10% as one of the raw materials, 18% phenolic resin, 18% styrene-butadiene rubber, 0.9% zinc stearate, 10.8% Carbon black, 27.9% barium sulfate, and 14.4% feldspar powder were used as raw materials. After blending and dry hot pressing, a resin-based friction material mixed with high-silicon iron tailings was made. When the friction and wear test was carried out at 350 ° C , friction coefficient (μ) and wear rate (V) are 0.40 and 0.55×10 -7 cm 3 / (N·m).
Embodiment 3
[0028] Using high-silicon iron tailings with a median diameter of 4.02 μm and a mass content of 10% as one of the raw materials, 18% phenolic resin, 18% styrene-butadiene rubber, 0.9% zinc stearate, 10.8% Carbon black, 27.9% barium sulfate, and 14.4% feldspar powder were used as raw materials. After blending and dry hot pressing, a resin-based friction material mixed with high-silicon iron tailings was made. When the friction and wear test was carried out at 350 ° C , friction coefficient (μ) and wear rate (V) are 0.30 and 0.45×10 -7 cm 3 / (N·m).
