[0042] see figure 1 , a UiO-66-(COOH) 2 / Dopamine synergistically modified carbon fiber reinforced paper-based friction material and a preparation method thereof, comprising the following steps:
[0043] Step 1: Take 15g of carbon fiber and soak it in acetone for 12-48 hours to remove the sizing agent and other impurities on the surface of the fiber. After completion, rinse it with deionized water for 3-5 times and dry it in an oven at a temperature of 80-150°C for 12-48 hours. , drying to obtain carbon fiber I with a clean surface;
[0044] Step 2: Dissolve 1.0-2.5 g of tris (Tris buffer) in 0.97-1.45 L of deionized water at room temperature and stir magnetically to obtain solution A, then dissolve 1.6-2.8 g of dopamine in 0.03 ~0.05L deionized water, conduct ultrasonic dispersion to obtain solution B;
[0045] Step 3: Use hydrochloric acid to adjust the pH of solution A to 8-10. During the continuous magnetic stirring process, the magnetic stirring rotation speed is 1000-...
Embodiment 1
[0053] Example 1 is a blank paper-based friction material that does not use modified carbon fibers in the prior art
[0054] Step 1: Decompose carbon fiber, aramid fiber and pulp fiber to form a fiber mixture, the mass ratio of carbon fiber, aramid fiber, pulp fiber and filler is 1.3:1.2:1.3:3.0, and add fillers including molybdenum disulfide and mica Powder, diatomaceous earth and kaolin, the wet samples were prepared by the principle of vacuum filtration and pulping and papermaking, and dried in an oven at a temperature of 55 ° C for 5 hours to obtain dry samples for later use;
[0055] Step 2: Impregnate the dry sample obtained in Step 1 in the modified phenolic resin with an impregnation concentration of 20%. After completion, dry it at room temperature and perform hot-press curing treatment. The hot-press temperature is 130°C, the curing time is 8 minutes, and the pressure is 10Pa. Thus a blank paper-based friction material was obtained.
Embodiment 2
[0057] Step 1: Take 15g of carbon fiber and soak it in acetone for 24 hours to remove the sizing agent and other impurities on the surface of the fiber. After the completion, rinse it with deionized water for 3 times, and dry it in an oven at a temperature of 120°C for 48 hours to obtain a carbon fiber with a clean surface. I;
[0058] Step 2: Dissolve 1.5g of tris (Tris buffer) in 0.97L of deionized water at room temperature, and perform magnetic stirring to obtain solution A, then dissolve 2.0g of dopamine in 0.03L of deionized water, and carry out Ultrasonic dispersion to obtain solution B;
[0059] Step 3: Use hydrochloric acid to adjust the pH of solution A to 9. During the continuous magnetic stirring process, the magnetic stirring rotation speed is 1300r, pour solution B into solution A, and make it fully mixed. Put the carbon fiber I obtained in step 1 into the above mixed solution, stir at room temperature, and dry in an oven after the reaction is completed at a temp...
