Problems solved by technology

[0003] 1. The main component of the inkjet glue used is organic matter. The glue is continuously carbonized during the heating process, and gradually loses its bonding effect on the dry particles, which causes the dry particles to be blown off or deviate from the preset temperature during the firing process of the bricks in the kiln. The phenomenon of the set position
[0004] 2. At present, due to the high market price of inkjet glue, and the existing technology needs to print a large amount of glue to achieve the fixation of dry particles, when the decorative area of ​​dry particles is more than 90 parts, the amount of glue per square meter must be more than 100 grams. To meet the production needs, because of the cost problem, most manufacturers can only use this process to produce a small amount of dry grain decoration products (the dry grain decoration area is within 30 parts), and the cost reason has greatly restricted the promotion and application of this process

Embodiment 1

[0032] see figure 1 As shown, in the case of short glaze line and limited production conditions, ceramic inkjet positioning ink combined with dry granulation equipment is used for dry granule positioning decoration. The specific implementation plan is as follows:

[0033] Production process: Step A: Sprinkle decorative bottom glaze → Step B: Print decorative patterns → Step C: Print ceramic inkjet positioning ink → Step D: Cloth dry granules → Step E: Blot dry granules → Step F: Dry → Step G: Spray protective glaze / fixative → Step H: Perform firing

[0034] In step A, the brick body is poured with a decorative bottom glaze through a disc bell jar, the amount of decorative bottom glaze: 610-620g / ㎡, the specific gravity of the decorative bottom glaze: 1.78-1.80, and the flow rate: 25-30s.

[0035] In step B, before the adobe is spray-printed with a decorative pattern, the temperature of the adobe is 40-60° C., and the adobe is spray-printed with an eight-channel inkjet machine....

Embodiment example 2

[0043] see figure 2 As shown, in the production process of Case 1, the amount of ceramic inkjet positioning ink is very large, which greatly increases the production cost and the burden on the nozzle of the inkjet machine. If the printing time is too long, ink shortage is prone to occur, and the nozzle needs to be washed frequently. It is not conducive to the continuity of the production process, and it will cause a certain loss to the production. This implementation case is to use the brick film-forming moisturizer combined with ceramic inkjet positioning ink and dry granulation equipment when the production conditions permit and the glaze line is long. The production method, this process method can greatly reduce the production cost (it can reduce the consumption of ceramic inkjet positioning ink by 60-80 parts), and the specific implementation plan is as follows:

[0044]Production process: Step A: Sprinkle decorative bottom glaze → Step B: Print decorative patterns → Step...

Abstract

The invention relates to a green brick film-forming moisturizing agent, ink-jet printing ink, decorative glue and preparation methods of the green brick film-forming moisturizing agent and the ink-jetprinting ink. The green brick film-forming moisturizing agent is prepared from the following components in parts by weight: 50-55 parts of polyvinyl acetate, 5-10 parts of ethyl alcohol and 35-45 parts of water. The preparation method of the green brick film-forming moisturizing agent comprises the steps that (1) according to the ratio in parts by weight of the raw material components, the polyvinyl acetate, the ethyl alcohol and the water are matched according to the proportion of (40 to 60):(5 to 10):(30 to 50) and fed into a stirrer to be mixed and stirred, the stirring time is 50 min, therotating speed is 250 r / min, and thus film-forming moisturizing agent raw stock is obtained; and (2) the film-forming moisturizing agent raw stock is sieved by a 100-mesh sieve, the flow rate of theadded water is controlled to be 27-30 s, the specific gravity is 1.05-1.10 g / cm<3>, and finally, a film-forming moisturizing solution is obtained.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a brick adobe film-forming moisturizer, inkjet printing ink, decorative glue and a preparation method for dry particle decoration. Background technique [0002] With the application of ceramic inkjet printing in ceramic production, the decoration methods on the surface of ceramic tiles are becoming more and more abundant. The ceramic tiles decorated with dry particle positioning have good glaze decoration effect, strong layered three-dimensional effect and delicate and smooth glaze texture. And favored by the market. The production process of dry granule positioning decorative ceramic tiles is to use the combination of ceramic inkjet printing glue and dry granule (high temperature frit) to apply dry granule. By designing the glue inkjet printing file that matches the decorative pattern, dry it when needed. Use a ceramic inkjet printer to spray glue on the granules, and the...
