Problems solved by technology

[0004] At present, the commonly used process is to disperse silver powder in organic solvent, apply it on the ceramic surface, and then sinter to make silver adhere. In this process, the organic solvent will produce a large amount of VOC during the sintering process, which will cause harmful effects on the environment and people's health.

Abstract

The invention discloses a spraying type ceramic surface-sintered silver paste which contains the following components: 50-60 parts of nanometer silver powder, 1-3 parts of glass powder, 5-10 parts of twain, 5-10 parts of polyvinylpyrrolidone, 5-10 parts of dimeticone, 3-5 parts of sweet almond oil and 15-20 parts of water. A preparation method comprises the following steps: adding water into a container; adding polyvinylpyrrolidone and stirring till dissolving; adding twain, dimeticone and sweet almond oil and stirring for 0.5-1 hour at 500-600rpm; lastly, adding the nanometer silver powder and the glass powder and stirring for 20-30min at 500-600rpm. According to the invention, the preparation process of the silver paste is simple, the silver layer is firm after the sintering and is difficult to fall off; the silver paste is nontoxic and harmless and contains no other heavy metal; when the silver paste is applied to the food container, the silver paste has disinfecting and bactericidal effects; the silver paste is wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of ceramic surface processing, in particular to a spray-coated ceramic surface sintered silver paste and a preparation method thereof. Background technique [0002] Porcelain is one of the most widely used utensils in people's daily life. With the improvement of people's material and cultural level, the requirements for the ornamental and functional requirements of ceramic products are getting higher and higher. Traditional ceramic products can no longer meet people's needs. need. [0003] 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. [0004] At present, the commonly used process is to disperse silver powder in organic solvent, apply ...
