[0016] Example 1
[0017] A smear-type ceramic surface sintered silver paste, which includes the following components in parts by weight: 45 parts of silver powder, 3 parts of sodium alginate, 2 parts of glass powder, 20 parts of polyethylene glycol, and 8 parts of sucrose isobutyrate , 1 part of rosin acid, 3 parts of pinitol oil, 20 parts of water.
[0018] The particle size of the silver powder is 0.2-1 μm.
[0019] The preparation method of the glass powder is as follows: Weigh the raw material according to the following mass percentage: SiO 2 15%, BaO 40%, TiO 2 30%, ZnO 9%, K 2 O 3.99%, B 2 O 3 2%, NiO0.01%, mixed uniformly, melted at 1200-1300℃ for 2 hours to obtain a glass liquid. The glass liquid is quenched in water at 10-20℃, dried and ball milled in a ball mill for 12 hours. Glass powder.
[0020] The preparation method of the smeared ceramic surface sintered silver paste is as follows: dissolve sodium alginate in water, add polyethylene glycol and stir evenly, record it ...
