Abstract

The invention discloses spread ceramic surface sintered silver paste, which comprises the following components in parts by weight: 45 to 55 parts of silver powder, 2 to 3 parts of sodium alginate, 2 to 3 parts of glass powder, 15 to 20 parts of polyethylene glycol, 5 to 8 parts of sucrose isobutyrate, 1 to 2 parts of an abietic acid, 3 to 5 parts of terpenic oil and 20 to 25 parts of water. A preparation method comprises the following steps: adding the silver powder into the water, adding the sodium alginate and the polyethylene glycol with stirring at 200 to 300rpm, and continuing stirring for 15 to 20min to obtain a solution A; dissolving the abietic acid into the terpenic oil, adding the sucrose isobutyrate, and performing uniform stirring to obtain a solution B; adding the solution B into the solution A, and performing stirring for 1 to 2h at 500 to 600rpm. According to the silver paste, the raw materials are readily available, a preparation process is simple, the silver paste is relatively low in cost, free of heavy metals, safe in use, green and environment-friendly, and no harmful gas is generated during sintering.

Description

technical field [0001] The invention relates to the technical field of ceramic surface processing, in particular to a smear-type ceramic surface sintered silver paste and a preparation method thereof. Background technique [0002] Silver is a kind of precious metal that people love. It has good decorative properties and is one of the most commonly worn decorations. In addition, silver also has bactericidal properties, so silver has begun to be applied to dining utensils to play It has the functions of disinfection, sterilization and preservation. [0003] At present, the application of silver in catering utensils is mostly directly made into cups, bowls, etc., which is relatively expensive and cannot meet the needs of the public. Using ceramic ware as a base and coating it with a silver layer can reduce the cost and give full play to the decorative and functional properties of silver. It has become the main direction of silver application in catering utensils. Contents of...
