Problems solved by technology

However, most of these self-cleaning technologies applied to ceramic tiles are currently in the laboratory stage, and are rarely promoted and applied in the market. There are two main reasons: 1. The sol prepared by hydrolyzing tetrabutyl titanate is used The thickness of the nano-titanium dioxide film is uneven, and the surface is prone to iridescent effect, which affects the surface effect of ceramic tiles; 2. Directly spray the nano-titanium dioxide solution on the surface of ceramic tiles with a brick surface temperature of 100-200°C. The surface is not firmly bonded, and it is easy to fall off. At the same time, the thickness of the titanium dioxide film produced is not uniform enough, and it will also produce an iridescent effect.
The uneven surface of ceramic tiles is the main reason for the uneven thickness of nano sol or nano liquid on the surface of ceramic tiles. Therefore, it is necessary to find a suitable method so that nano sol or nano liquid can be evenly coated on the surface of ceramic tiles to solve the problem of ceramic tiles. The problem of uneven thickness of the nano-film on the surface

Abstract

The invention discloses an organic titanium ink for inkjet printing, which comprises the following components according to the weight percentage of raw materials: 5-15% of butyl titanate, 20-30% of ethylene glycol, and 4-12% of triethanolamine , absolute ethanol 2-5%, diethylene glycol diether 3-5%, organic alkanes 20-35%, ether 15-20%. Through the selection and proportioning of special raw material components, the invention makes the prepared organic titanium ink have low surface tension and is easy to form a film. It is not only suitable for inkjet printing operations, but also can form a thickness Uniform film layer, thus effectively avoiding the disadvantages of uneven thickness of the sol film caused by uneven surface of the object to be coated or uneven atomized ink droplets when the traditional sol ink is applied, and the organic titanium ink can be used in the post-calcination process. A nano-titanium dioxide film with uniform thickness is generated, thereby effectively avoiding the iridescence effect caused by uneven film thickness in the prior art.

Description

technical field [0001] The invention relates to the field of building material coatings, in particular to an ink for inkjet printing of building materials. Background technique [0002] Ceramic tiles are widely used in indoor and outdoor decoration. Organic matter in the air is easily adsorbed on the surface of ceramic tiles. When organic matter adheres to the surface of ceramic tiles, ceramic tiles can easily absorb inorganic particles in the air, causing ceramic tiles to absorb dirt and change color. It needs to be cleaned regularly, and the surface of the ceramic tile is relatively firmly bonded to the dust, which is not easy to clean and requires a special solution for cleaning. Especially the surface cleaning of exterior wall bricks of buildings usually requires high-altitude operations, which is difficult to clean and expensive to clean. [0003] In order to solve the problem of dirt absorption on the surface of ceramic tiles, many scientific research institutions hav...
