Technical Field

The invention belongs to the technical field of ceramic rock plates, and particularly relates to a glaze for improving the rubber roller blank printing quality of a ceramic rock plate, a preparation method and a control method.

Background

The ceramic rock plate is a brand new product emerging from the building ceramic industry in recent years, and the appearance of the product is mainly characterized in that the area is large, and the upper surface area is not less than 1.62m²(ii) a Secondly, the thickness is thin, and the thickness of the green brick is less than 6 mm; thirdly, the glaze layer is thin, the blank body and the glaze layer have no obvious boundary, and the brick is similar to a whole brick. Because of the characteristics of the ceramic rock plate, the traditional glazing process can not meet the production requirement because the traditional glazing process uses water-based glaze for decoration, the glaze layer is thicker when glazing is carried out by adopting a glaze spraying mode, the specification of the ceramic rock plate is larger, glaze spraying ripples are easy to appear during production, and the control difficulty of the decorative effect is high; in the glaze spraying process, because the glaze slip has large water content, a large amount of water can weaken the strength of a green brick, the green brick is easy to crack, and the half yield of products is influenced; the screen printing glazing does not have corresponding printing equipment, and the even distribution of the glaze amount is difficult to ensure by printing products with large specifications, and the printing surface has a plurality of defects; although the rubber roll printing has a corresponding large-size roller printing machine, the existing process for printing on a large-area blank still has some defects, including the problems of thin glaze layer, insufficient covering capacity, uneven thickness of the glaze layer, glaze shortage, streak and the like.

The process has the advantages that the digital glaze is oily, the permeation rate of glaze materials to a brick blank is low after glazing, the influence on the strength of the brick blank is small, meanwhile, the process adopts a numerical control technology to carry out glazing, the glaze quantity is uniformly distributed, the thickness of a glaze layer can be very thin (less than 0.05 mm), and the digital glaze has the advantages that the traditional glaze spraying/glaze spraying process cannot reach, so the process is widely applied to the development and production of the ceramic rock boards. However, all things are twosided, and although the advantages of the digital glaze are outstanding, the digital glaze has certain limitations: firstly, the digital glaze is an oily substance, and is used for decorating a ground coat layer of a ceramic rock plate, so that the unclear decorative pattern of a subsequent procedure is easily caused, because the digital ink for decorating the pattern is also an oily substance, compared with water, the penetration rate of the oily substance to a green brick layer is much slower, and the time for staying on the surface of a green brick is longer, so that the diffusion phenomenon is easily caused when the decorative ink is sprayed after the digital glaze is applied to the green brick, and the unclear decorative pattern is caused; secondly, the application range of the digital glaze is narrow, once the digital glaze is used, the fire degree and the performance of the glaze cannot be adjusted according to production requirements, the ceramic rock plate products are produced in a customized manner, the requirements of each client or market are different, the specification, the thickness, the glaze texture and the like of the products are frequently switched, the fluctuation of a production platform is easily caused, when the digital glaze is used for production in the face of the fluctuation, the adaptability adjustment cannot be carried out on the aspect of the glaze, and the difficulty is increased for the production stability control; the use cost of digital glaze is high, and hardware facilities on the one hand drops into greatly, needs to have special ink jet flower machine and equipment fixing place, and the glaze cost is high on the other hand, and the unit price of imported digital glaze is generally 100 ~ 200 yuan/kg, compares with traditional glaze 3 ~ 5 yuan/kg, and the price is raised dozens of times, has increased enterprise's manufacturing cost burden by a wide margin.
