Abstract

The invention discloses slurry for an anti-static device. The slurry is prepared from the following raw materials in percentage by weight: 10-15% of an organic carrier, 10-15% of glass powder, 10-20% of a wrapped conductive material, 20-30% of a spherical semiconductor material ZnO, 10-20% of spherical aluminum oxide powder, 1-5% of spherical nano Pt powder or Pd powder, and 1-5% of a solid powder dispersant.

Description

technical field [0001] The invention relates to a paste for antistatic devices. Background technique [0002] 1. Zinc oxide varistor [0003] Varistor ceramics refer to semiconductor ceramics whose resistance value has a significant nonlinear relationship with the applied voltage. The resistance value of the piezoresistor thus made can switch back and forth between the linear high-resistance state and the approximately conduction low-resistance state with the rise and fall of the external field voltage. It is a typical "smart" electronic component. Varistors are usually connected in parallel with the protected circuit or electronic components. When there is an overload in the circuit, the varistor can automatically bypass the overload, thereby preventing the circuit or components from being damaged. [0004] Zinc oxide varistor is a polycrystalline ceramic material with ZnO as the main body, added with various metal oxides (Bi2O3, MnO2, Co2O3, Cr2O3, Sb2O3, etc.), and sint...
