Embodiment 1
[0026] Take 150g of the original whiskers of potassium tetratitanate and place it in a 2L ball milling tank. According to the mass ratio of balls and materials at 2:1, put the balls and powder in the ball milling tank for ball milling for 10 hours, take out the milled potassium tetratitanate powder and disperse Stir in deionized water with a magnetic stirrer for 5 hours, vacuum filter, and dry. Take 100 g of potassium tetratitanate powder after washing and drying, add deionized water to disperse, and add 0.5 % stearic acid, placed in a collector type constant temperature heating mixer at 80°C and stirred for 20min, suction filtered, dried at 80°C for 5h, after drying, add 3% stearic acid relative to the quality of the obtained powder, and place in the collector Stir at 85°C for 18 minutes in a thermal constant temperature heating mixer, filter with suction, and dry at 90°C for 4 hours, place the obtained modified potassium tetratitanate whiskers in deionized water, adjust the p...
Embodiment 2
[0029] Take 100g of the original whiskers of potassium tetratitanate and put it in a 2L ball milling tank. According to the ball-to-material ratio of about 2:1, put the balls and powder in the ball milling tank for 5 hours, and take out the milled potassium tetratitanate powder and disperse In deionized water, place it on a magnetic stirrer and stir for 1 hour, vacuum filter, and dry, take 100 g of potassium tetratitanate powder after washing and drying, add deionized water to disperse, and add relative potassium tetratitanate to the suspension Stearic acid with 5% powder mass is placed in a collector-type thermostatic heating stirrer and stirred at 100°C for 5 minutes, suction filtered, dried at 120°C for 1 hour, and 1% stearic acid relative to the obtained powder mass is added after drying. Put it in a collector-type thermostatic heating stirrer and stir it at 80°C for 20 minutes, filter it with suction, and dry it at 80°C for 5 hours. Put the obtained modified potassium tetr...
