The invention belongs to the technical field of magnetic materials, and discloses a start-stop permanent magnet starter magnetic pole new material and a preparation method thereof. The start-stop permanent magnet starter magnetic pole new material comprises an original mixed magnetic material and boric acid, aluminum oxide, lanthanum trioxide and cobalt oxide materials, wherein the adding proportion of the boric acid is 0.1%-0.5%, the adding proportion of the aluminum oxide is 0.2%-0.8%, the adding proportion of the lanthanum trioxide is 0.3%-0.8%, and the adding proportion of the aluminum oxide is 0.2%-0.5%. By adding boric acid, the magnetic pole strength can be improved; aluminum oxide is added, so that the demagnetization resistance and the high and low temperature impact resistance ofthe magnetic pole can be improved; the consistency and density of a magnetic field can be improved by increasing the ratio of lanthanum trioxide to cobalt oxide. Compared with an original formula, the magnetic flux performance of the magnetic pole is improved, and the risk of durable demagnetization is greatly reduced.
本发明属于磁性材料技术领域，公开了一种启停永磁起动机磁极新材料及其制备方法，启停永磁起动机磁极新材料包括原混合磁性材料和硼酸、三氧化二铝、三氧化二镧、氧化钴材料；硼酸的添加比例为0.1％‑0.5％，三氧化二铝的添加比例为0.2％‑0.8％，三氧化二镧的添加比例为0.3％‑0.8％，三氧化二铝的添加比例为0.2％‑0.5％。本发明通过加入硼酸可以提高磁极强度；加入三氧化二铝可以提高磁极的耐退磁性能及抗高低温冲击能力；通过加大三氧化二镧、氧化钴比例可以提高磁场的一致性和致密度。相对比原配方，磁极磁通性能有所提高，大大降低了耐久后退磁的风险。
