Description
Technical field
The present invention relates to ceramic field, specifically the preparation method of a kind of high-strength ceramic shale base substrate and the method for making ceramic product with this base substrate.
Background technology
The decorative appearance mode of domestic ceramics has: white tire, with transparent or opal glaze decoration；Color glaze, decorates with coloured glaze；Colored drawing, with color material colored drawing or decal paper, painted decoration also can be divided into overglaze color, underglaze colour, in-glaze decoration.
Colored drawing flower face is in enamel layer hereinafter, referred to as underglaze colour, glaze layer protection colored drawing flower face, has health, the advantage such as attractive in appearance.Hand painting or decal paper, be all the more operation of recruitment, and production efficiency is relatively low, and cost is also higher.Ceramic industry is innovated the color technology of transfer print and technique, has adopted transfer print color machine that colorant directly prints to surface of ceramic products.Due to the variation of domestic ceramics device shape, the print head of print coloured silk is that soft silica gel is made, it is adaptable to the printing of arc goods.
Due to the color process of transfer print, silica gel print head pressure needs certain pressure when being attached to surface of ceramic products, needs, through biscuiting (800-900 DEG C), to make goods have certain intensity after ceramic molding, it is applicable to print coloured silk, carries out glazing again through printing color product and burn till.The conventional shale blank strength relatively low (bending strength is at about 1.5MPa) after ceramic ware for daily use molding, it is prone to damaged in the color process of print, if shale blank strength is improved (bending strength reaches 2.5MPa), then can bear the pressure that print is color.Directly print coloured silk on shale base substrate, without biscuiting, it is possible to saving cost and raise labour productivity, product decoration effect is more preferably.Domestic ceramics industry will improve household ceramic blank intensity, make it directly transfer print coloured silk on shale base substrate, become the problem of technological innovation and research of technique.
Summary of the invention
For solving the problems referred to above, the invention provides the preparation method of a kind of high-strength ceramic shale base substrate and the method making ceramic product with this base substrate.
The preparation method of the ceramic shale base substrate of the high intensity of the present invention, it is characterised in that comprise the following production steps that
(1) Slug preparing
Taking Kaolin 42-46 weight portion, Anhydrite 18-22 weight portion, quartz 14-16 weight portion, ball clay 6-8 weight portion, useless porcelain 6-8 weight portion, bentonite 2-4 weight portion, kieselguhr 4-6 weight portion is as raw material；
Above-mentioned useless porcelain is that daily ceramic product is burning till the scrap produced afterwards, with hammer, scrap is hammered into fragment and prepares；Above-mentioned Kaolin is the Kaolin originating from Fujian Longyan, prepares after eluriating and removing partial impurities；
Add clear water after being mixed by above-mentioned raw materials and carry out wet ball grinding, cross 220 mesh sieves through ball milling raw material, cross magnetic separator de-ironing deironing through the raw material that sieves, become clod through deironing raw material by pressure filter filter pressing, by pug mill, clod is carried out pugging, and the blank preparing quality moisture content 22-33% is standby；
(the basic role of materials application in above-mentioned blank formulation；
Kaolin, Anhydrite, quartz are household porcelain production raw materials three is the stock in formula, constitutes the main body of ceramic ware for daily use.During material usage matches, taking into account the plasticity of product molding, the formation of the reaction of sintering process material and mullite, goods have the effects such as higher whiteness.
Useless porcelain is the material through burning till, and can suitably reduce the temperature that goods burn till, and shortens firing time, saves production cost, is also a kind of twice laid.
Ball clay can make the shale base substrate of molding have higher intensity when dry, but be prone to cause shale body drying to shrink and strengthen, and causes blank cracking.Therefore, addition should appropriateness.
Bentonite is the plasticizer of ceramic batch, can improve the plasticity of blank, with ball clay with the use of, can correspondingly stablize the intensity of shale base substrate.
Kieselguhr can improve the viscosity of blank, interacts with ball clay, bentonite, the qualification rate of product molding process can be made to improve, and blank strength is maintained.)
(2) molding
Take above-mentioned standby blank, adopt roller head machine to carry out roll forming；Forming process adopts rolling depression method at a slow speed, and the rolling time of every base substrate is that the 15-16 second, (every conventional base substrate rolling time was the 9-10 second；Using rolling depression method at a slow speed that molding shale green density can be made to improve, intensity improves accordingly)；
Above-mentioned roller head machine is equipped with roll die, including male model and master mold；Male model is that politef is made；Master mold is that the three A superfine Gypsum Fibrosum powders that Macheng town three, Jingmen power plastering company limited produces are made；After master mold is made, adopting above-mentioned blank, be deployed into, with clear water, the mud that concentration is 50 Baume degrees, mud injects plaster mold intracavity, mud stops 30-40 minute in die cavity, reduces the alkalescence on gypsum mold surface；The mud time of staying by mud eliminating in plaster mold, rinses gypsum mold with clear water after arriving, and cleaned gypsum mold natural drying is standby；(effect embathing gypsum mold with mud is to make the goods easy demoulding of goods in roll forming, the pug of goods not sticking mould)
(3) repaired biscuit
Billet surface through molding is carried out reconditioning；First with sand paper to billet surface fine grinding, make billet surface smooth, then with the block ivalon of silk stocking parcel, add clear water and billet surface is carried out fine grinding, make billet surface smooth, be conducive to follow-up print color；
(4) dry
Through the base substrate natural drying of repaired biscuit to quality moisture content 6-8%, namely prepare the ceramic shale base substrate of high intensity.
The method making ceramic product of the present invention, it is characterised in that the shale base substrate prepared in aforementioned manners, adopts stamp material to carry out print coloured silk, then uses pottery clear frit, burn till through routine, be eventually fabricated underglaze colour domestic ceramic product.
The high-strength ceramic shale base substrate that the present invention prepares, it is adaptable to adopt the color machine of transfer print directly to carry out print coloured silk on shale base substrate.Shale billet surface is smooth, intensity high (bending strength reaches 2.5MPa after tested), and in the process making ceramic product, when adopting stamp material to carry out printing coloured silk, shale base substrate is not damaged, prints coloured picture case complete display.
