Embodiment 1
[0031] 1. Prepare the magnetic powder mixture according to the following formula and conduct experiments:
[0032] Flaky NdFeB magnetic powder (sheet diameter 45um, thickness-to-diameter ratio 1:16) 85wt%
[0033] Polyurethane 8.5wt%
[0034] Polyethylene 3.5wt%
[0035] Silicone oil 1.4wt%
[0036] Epoxidized soybean oil 1.3wt%
[0037] Silica powder (Fisher particle size 0.6um) 0.3wt%
[0038]The above-mentioned components are mixed evenly with a high-speed mixer (high-speed mixer GH-10DY type, Beijing Plastic Machinery Factory), and then mixed with an open mill (open mill XK-160, Wenzhou Eurasia Rubber and Plastic Machinery Co., Ltd.) The obtained mixture was mixed fully and evenly, and finally a magnetic sheet with a thickness of 1.5 mm was made with a calender (calender XY-2-230, Wuxi Wangda Rubber and Plastic Machinery Factory). 2. Determination of magnetic properties, tensile strength and elongation at break of magnetic sheets; flexibility test, salt water resistan...
