Embodiment 1
[0024] A preparation method of phase change microcapsule / UHMWPE wear-resistant material, comprising the following steps:
[0025] Step 1, the preparation of microcapsule powder
[0026] (1) Mix formaldehyde solution with a molar ratio of 3.6:1 and melamine, add an appropriate amount of distilled water to form a mixed solution, and stir the mixed solution in a constant temperature water bath at 70°C until the system is transparent, wherein the mass percent concentration of the formaldehyde solution is 37 %, then add a NaOH solution with a mass percentage concentration of 10% to adjust the pH of the system to 10, and the temperature of the water bath is lowered to 40°C and continued to stir for 30 minutes to obtain a formaldehyde-melamine prepolymer;
[0027] (2) According to the weight ratio of formaldehyde-melamine prepolymer and paraffin prepared in step (1) to 1.5:1, weigh the paraffin with a phase transition temperature of 48~50°C, and add 37.6% of the weight of the weighed...
Embodiment 2
[0035] Prepare microcapsule powder according to the preparation method of step 1 in Example 1, and then weigh 80% of the UHMWPE powder and 20% of the microcapsule powder prepared in step 1 according to the weight percentage, and then carry out step 2 to step 6 in Example 1 steps, the test results are as follows figure 1 shown.
Embodiment 3
[0037] Prepare microcapsule powder according to the preparation method of step 1 in Example 1, and then weigh 70% of the UHMWPE powder and 30% of the microcapsule powder prepared in step 1 according to the weight percentage, and carry out step 2 to step 6 in Example 1 in sequence steps, the test results are as follows figure 1 shown.
