Technology for treating tile before ink spraying

Abstract

The invention discloses a technology for treating a tile before ink spraying. The surface of the tile is automatically cleaned by the rotating cleaning cloth of a machine, and tiny dust is blown off by compressed air. The technology is characterized in that coating liquid is prepared from special chemical raw materials such as 30 to 40 percent of acrylic resin, 20 to 30 percent of modified acrylic resin, 20 to 30 percent of polyurethane monomer, 8 to 12 percent of frankincense oil and 3 to 7 percent of camphor oil by the conventional method, and accords with the standards of the solid content of 35+ / -5 percent (nonvolatile matters), the viscosity of 3,000 to 3,500cps and the ink absorption drying time of 3 minutes, and the tile is uniformly coated and subjected to ink spraying after about 3 minutes. The technology has the advantages that manufacturing cost is low, the process is simple and easy to operate, an actual effect is achieved, and effects of high ink spraying reduction performance, water resistance, boiling water resistance, open flame resistance and ultraviolet resistance can be achieved.

Description

technical field [0001] The invention relates to the field of inkjet technology, in particular to a treatment technology before inkjet. Background technique [0002] Ceramic tile inkjet printing technology is derived from the principle of digital inkjet printing of paper. Inkjet technology is considered to be a major trend in the future development of ceramic tiles in the industry due to its advantages in patterns and colors. However, inkjet printing on paper is organic Ink, while ceramic inkjet printing uses ceramic glazes synthesized from inorganic materials, which must also be calcined at high temperatures. The conversion from organic to inorganic is not easy. The tile itself does not absorb ink. The ink sprayed on it will scatter without forming an image. Accumulation of ink, slow drying speed, poor printing effect, etc. In order to solve this problem, tile inkjet pretreatment technology appears on the market, which adopts a kind of coating, which is applied before inkj...

Problems solved by technology

The conversion from organic to inorganic is not easy. The tile itself does not absorb ink. The ink sprayed on it will scatter without forming an image. Ink accumulation, slow drying speed, poor printing effect, etc.

In order to solve this problem, tile inkjet pretreatment technology appears on the market, which adopts a kind of coating, which is applied before inkjet. , the effect of UV resistance is not very ideal
