Abstract
The present invention relates to glaze decoration technology for ceramic sanitary utensils, which comprises the processes of body spraying a ground glaze, preparing a fancy glaze, dryness and firing. The present invention also increases the following technology that (1) the preparing processes of a wire mesh and a framework thereof are increased; (2) the wire mesh with the framework is placed on a body spraying the ground glaze, the fancy glaze can be used for wire mesh spraying decoration, and a wire mesh pattern is formed; (3) a fixing agent or a clear glaze is sprayed on the glaze layer of the formed wire mesh pattern. The present invention can realize disposable large area integration decoration for ceramic sanitary utensils of various complicated shapes, and fine, clear and transitional well-bedded patterns and figures can be formed on the glaze layer, such as imitative stone grains, imitative wood grains, etc. The present invention has the advantages of vivid effect and intense natural aesthetic feeling.
Description
The invention belongs to the BUILDING AND SANITARY CERAMICS TECHNOLOGY field.
At present, two kinds of technologies of main employing on the china sanitary ware glaze is decorated: a kind of is applique decoration technology (referring to " domestic ceramics manual industry ", P346-348, light industry publishing house version in 1984), wherein can be divided into low temperature decoration firing and high temperature decoration firing again.Applique process is simpler, can form various meticulous patterns at the sanitary equipment glaze, is extremely difficult but carry out large-area whole applique decoration on the cleaners and polishes surface of moulding complexity.And pattern is coarse during the low temperature decoration firing, and resistant, corrosion resistance are poor.During the high temperature decoration firing, to having relatively high expectations of marble paper, defectives such as product snuff are more.Another kind is spraying decoration high temperature single firing process (referring to " a domestic ceramics manual industry ", P351-353, light industry publishing house version in 1984), and its technological process as shown in Figure 1.This method motif transition is better, and turnover is gentle closes, and can carry out integral body decoration to the large tracts of land curved surface, but its weak point formed pattern that is spraying decoration and grain pattern are meticulous inadequately, and to some wood grains, bag class pattern, decorative effect is not good especially.Simultaneously, complicated operation, efficient is low, and operator's skill is had relatively high expectations.In addition, in the architectural pottery field, a kind of screen printing technology that is applied to wall floor tile, glazed tile production is arranged.Its method is with scraper plate fancy glaze to be scraped on the adobe surface under the tensioned screen.This method need adopt water-retaining property, fancy glaze that lubricity is good, and silk screen will have certain force of strain (5～8N/cm
2).The clear patterns of printing off by silk screen, meticulous, transition nature, can print off various patterns such as bag, wood grain but this screen printing technology can only be used for the surface is the brick series products on plane, for many, the complex-shaped china sanitary ware of male and fomale(M﹠F), want that carrying out integral body by the screen printing technology decorates possibility.
The objective of the invention is at above-mentioned the deficiencies in the prior art part, providing a kind of can carry out the whole decoration of large tracts of land curved surface, the glaze decoration technology that formed pattern and grain pattern are clear, meticulous, transition is natural to china sanitary ware.
The present invention adopts following technical scheme to realize: the present invention includes base substrate spray ground-coat enamel, fancy glaze preparation, dry, the firing process of existing ceramic spraying decoration high temperature once-firing decoration technology, and increase following technology (as shown in Figure 2):
(1) preparation section of increase silk screen and framework thereof;
(2) silk screen of placement tape frame on the base substrate that sprays ground-coat enamel carries out the silk screen spraying decoration with fancy glaze, forms silk-screen patterns, and the tension force of silk screen is less than 2N/cm
2
(3) forming on the glaze of silk-screen patterns spray in order to the fixedly fixative or the clear frit of silk-screen patterns.
For reaching the optimum efficiency of silk screen spraying decoration, make silk screen in framework, be in relaxed state, place on the base substrate and can be adjacent to billet surface.Simultaneously, be equipped with that dehydration is fast, proportion is high, the fancy glaze of certain flowability is arranged.Its proportion is preferably in 1930～2230Kg/m
3, viscosity is 900～1250PaS.In addition, distinct more for making pattern, to can be compared to the colorant addition that existing pattern jetting technique adopts most the biggest for the colorant addition in the fancy glaze, with 30～90% for well.
Can adopt soluble organic adhesive in order to the fixing fixative of silk-screen patterns among the present invention program.
According to silk screen spraying decoration decoration process method of the present invention, not only can carry out the whole decoration of large tracts of land curved surface, and on glaze, form natural, clear, meticulous pattern and the grain pattern of transition china sanitary ware.
The present invention compared with prior art has the following advantages:
1, can produce glaze and have well arranged, meticulous, the china sanitary ware of imitative bag, imitative wood grain and other patterns and grain pattern clearly of transition, effect is true to nature, and natural aesthetic feeling is strong.
2, can carry out the whole decoration of disposable large tracts of land, production efficiency height, percentage of A-class goods height to the china sanitary ware of different shape complexity.
3, simple to operate, less demanding to workman's operation skill.
Fig. 1 is existing spraying decoration high temperature single firing process flow process sketch drawing;
Fig. 2 is a process flow diagram of the present invention;
Fig. 3 is a silk screen spraying decoration operation schematic diagram of the present invention.
Below in conjunction with embodiment and accompanying drawing the present invention is elaborated.
Embodiment one imitative wood grain china sanitary ware glaze is decorated
Its concrete steps are:
1, on base substrate, sprays the ground-coat enamel of required color.
2, preparation fancy glaze, the chemical composition and the main control parameters of fancy glaze are as follows:
