The invention discloses silver-plated micron-sized particles as well as a preparation method and application thereof. According to the method, firstly, the surfaces of the non-metal inorganic particles are coated with the metal layers, the binding force of silver and the non-metal inorganic particles is improved, and then the stability of the particles is improved through further coating of the silver layers. Meanwhile, in the preparation process, the conductivity and compactness of the obtained silver-plated micron-sized nonmetal inorganic particles are improved through treatment at a specific temperature. The silver-plated non-metal inorganic particles can be used for conductive anti-static shielding slurry, paint, printing ink, rubber, plastic, chemical fiber and other products. 本发明公开镀银微米级颗粒及其制备方法和用途。本发明首先通过在非金属无机颗粒表面包覆金属层，提高了银与非金属无机颗粒的结合力，然后通过进一步包覆银层，提高了颗粒的稳定性。同时在制备过程中，通过特定温度的处理提升了得到的镀银微米级非金属无机颗粒的导电性和致密性。本发明得到的镀银非金属无机颗粒可用于导电防静电屏蔽用浆料、油漆、油墨、橡胶、塑料、化纤纤维等产品。
