Abstract

The invention discloses metalized slurry of a power battery sealing connector and a preparation method of the metalized slurry. The metalized slurry comprises a metalized raw material and an organic adhesive, and the mass ratio of the metalized raw material to the organic adhesive is 8-9 : 1-2. The metalized raw material comprises a metal oxide active agent, and the metal oxide active agent comprises the following components in percentage by mass: 10-15% of aluminum oxide powder, 8-15% of silicon dioxide, 1-2% of titanium dioxide and 1-2% of tantalum pentoxide. The organic adhesive comprises ethyl cellulose, terpene alcohol, organic silicon defoamer and an organic silicon flatting agent, and the mass ratio of the ethyl cellulose to the terpene alcohol to the organic silicon defoamer to theorganic silicon flatting agent is 10-15 : 1000-1199 : 3 : 5. The roughness of the metalized surface of the sintered battery sealing connector is reduced to be less than or equal to 1.0 [mu]m, and themetalized sealing strength is improved to be more than or equal to 120Mpa.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power batteries, and in particular relates to a metallization paste for a sealed connector of a power battery and a preparation method thereof. Background technique [0002] Due to the performance characteristics of ceramics such as high strength, small dielectric constant, high volume resistivity, small dielectric loss and high thermal shock resistance, ceramic parts themselves are excellent insulating materials, and they do not have solderability themselves. Solder usually cannot Its infiltration and metallization are an effective way to realize the sealing of ceramics and metals. [0003] The raw materials and formulations used in ceramic metallization are the key to metallization. In actual production, different manufacturers have different special raw material formulas. The paste or slurry composed of specific formula raw materials can effectively achieve the coating of specific pa...
