The invention discloses a nanocrystalline magnetic core packaging organic silicon binder and a preparation method thereof in the field of organic silicon binders. The nanocrystalline magnetic core packaging organic silicon binder comprises the following components in parts by weight: 80-100 parts of an organic silicon polymer, 10-30 parts of filler, 0.5-1 part of a dispersing agent, 1-3 parts of a stabilizer and 1-1.5 parts of a photoinitiator. According to the invention, polysiloxane with dense long-chain alkyl groups is cross-linked to form an organic silicon polymer with crystallization capability, and the crystallization capability of organic silicon is changed after ultraviolet curing treatment, so that the thermal conductivity of the packaging material is improved. 本发明公开了有机硅粘结剂领域的一种纳米晶磁芯封装有机硅粘结剂及其制备方法，包括如下重量份的组分：有机硅聚合物80-100份、填料10-30份、分散剂0.5-1份、稳定剂1-3份、光引发剂1-1.5份。本发明提出通过具有密集长链烷基集团的聚硅氧烷进行交联，形成具有结晶能力的有机硅聚合物，经过紫外固化处理后，改变有机硅的结晶能力，从而提高封装材料的导热性。
