Abstract
The invention discloses ceramic clay used for powder paint decoration and a production method of powder paint decorative ceramic prepared from the same. The ceramic clay is prepared from the following components by weight percent: 10-25% of diatomite, 15-25% of elutriation mud, 20-30% of kaolin, 25-35% of feldspar and 5-15% of dolomite. The production method comprises the following production steps: taking the components to prepare ceramic clay in proportion, moulding into a porcelain body, and firing; electrifying the porcelain body; spraying the electrified powder paint on the porcelain body; heating the porcelain body; and discharging the porcelain body, and cooling to prepare the product. By adopting the ceramic clay and the ceramic product prepared by the production method, the decorative effect of ceramic glaze can be realized, volatile gases can be eliminated, the production cost can be reduced, energy can be saved and the environment can be protected. Therefore, the invention provides the development direction of domestic exported artistic ceramic production enterprises.
Description
Technical field
The present invention relates to ceramic field, specifically is a kind ofly to can be used for ceramic porcelain mud that powder coating decorates and make the production method of powder coating decorative porcelain with it.
Background technology
Life is divided into four classes usually with pottery: domestic ceramics, the art pottery, architectural pottery, snitaryware.The art pottery wherein is also referred to as the display art pottery, mainly is to be used for furnishing and viewing and admiring, and is not used in contacting foodstuff and daily use.Therefore, the material that has only the art pottery to decorate can be non-silicates, i.e. the decoration of non-enamel.
The art pottery that adopts enamel to decorate has higher value, as crystalline glaze, tri-coloured glazed pottery etc., and as the art pottery original work of collectibles, most decorations that adopt the silicates material.And produce in enormous quantities, comprising China's art pottery product of outlet in enormous quantities at present, its price is not high, adds after employing enamel is decorated and burns till processing, and energy consumption and cost are difficult to descend.Over nearly 20 years, in China, particularly the guangdong ceramic producing region adopts organic coating that the art pottery is decorated in large quantities, and the organic coating that adopts is pyroxylin(e)finish, polyester paint etc. substantially at present, after the coating of adding solvent is decorated the art pottery, though can produce the product of mannerism, texture is relatively poor, coating abrasion performance is poor, and residual tedious paint-like flavour, production cost is not low yet, both uneconomical yet not environmental protection.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly can be used for ceramic porcelain mud that powder coating decorates and make the production method of powder coating decorative porcelain with it.
A kind of ceramic porcelain mud that can be used for the powder coating decoration is characterized in that, is made by following compositions in weight percentage: diatomite 10～25%, elutriation mud 15～25%, kaolin 20～30%, feldspar 25～35%, white clouds soil 5%～15%.
Described diatomite specifically can be sea soil.Sea soil is a kind in the diatomite, and color is more black, and its composition is mainly silicon, contains humic substance and calcareous simultaneously.
In the conventional ceramic raw materials formulation, diatomaceous add-on is very little.Because contain organic substance in the diatomite, organic substance decomposes volatilization in goods burn till, and causes to have a large amount of occupancy pores in the product, and the goods water-intake rate increases, the glaze quality after influencing product and burning till.And the ceramic matrix that adopts this prescription to make does not need glazing, but spray coating powder paint.Add relatively large diatomite, purpose is pore and the water-intake rate that increases carcass, makes the conductive processing that helps carcass before the follow-up powder spraying construction, also helps product and reduces temperature in firing, save energy and improve the harvest rate of product.
Production method with the clay powdered coatings decoration of above-mentioned ceramic porcelain pottery comprises following production stage:
(1) get said components and make ceramic porcelain mud in proportion, just fire without glazing after overmolding is made ceramic matrix, firing temperature is 950～1180 ℃, and fired ceramic matrix water-intake rate is 16～28%;
Fired ceramic matrix has certain intensity, has the pore that is evenly distributed in the carcass wall;
(2), ceramic matrix is seated in atmospheric moisture is under 40～80% the environment, put more than 0.5 hour after, ceramic matrix hung on the charged metal hook switches on, electric current is 85～90 milliamperes; Make the ceramic matrix surface produce weak current;
(3) will spray to charged ceramic matrix through the powder coating of conductive processing with spray gun, powder coating is adsorbed on the ceramic matrix surface equably;
(4) ceramic matrix that will be adsorbed with powder coating hangs in kiln internal heating 10～40 minutes, and temperature is controlled at 160～220 ℃;
In the heat-processed, the moisture volatilization in the ceramic matrix, powder coating is fusion and levelling under significant temp, makes the ceramic matrix surface generate the dope layer of adhere firmly equably;
(5) naturally cooling of coming out of the stove of the ceramic matrix after will heating makes product;
The coating of product surface is smooth, does not have the volatilization smell, and coating exactly likes enamel layer, makes goods produce the aesthetic feeling that enamel is decorated porcelain.
Above-mentioned powder coating can adopt the powder coating of epoxy type.
With the ceramic product that ceramic porcelain mud of the present invention and production method are made, can reach the effect that enamel is decorated, can eliminate the smell that volatilizees simultaneously, reduce production costs, not only energy-conservation but also environmental protection, this will be a domestic export art pottery manufacturing enterprise developing direction from now on.
Embodiment
The present invention will be described in detail to reach Comparative Examples by the following examples.
Embodiment: get diatomite 20% by weight percentage, eluriate mud 20%, kaolin 22%, feldspar 28%, white clouds soil 10% makes ceramic porcelain mud, after making ceramic matrix, overmolding just fires without glazing, firing temperature is 1080 ℃, and fired ceramic matrix water-intake rate is 20%;
It is under 55% the environment that ceramic matrix is seated in atmospheric moisture, puts after 5 hours, ceramic matrix is hung on the charged metal hook switch on, and electric current is 90 milliamperes;
To spray to charged ceramic matrix through the powder coating of conductive processing with spray gun, powder coating is adsorbed on the ceramic matrix surface equably;
The ceramic matrix that is adsorbed with powder coating is hung in kiln internal heating 30 minutes, and temperature is controlled at 200 ℃;
The ceramic matrix naturally cooling of coming out of the stove with after the heating makes product of the present invention.
The coating of product surface is smooth, does not have the volatilization smell, and coating exactly likes enamel layer, makes goods produce the aesthetic feeling that enamel is decorated porcelain.
Comparative Examples 1: different with embodiment is, diatomaceous add-on in the porcelain mud is kept to 5%, makes the product of Comparative Examples 1.
