CN101024569A - Burning-free ceramic product and its preparing method - Google Patents

Abstract

The invention relates to a non-burning ceramic that is made up from sand 10-30wt%, clay 5-15wt%, concrete 5-15wt%, gypsum 5-10wt%, MgO 20-40wt%, bittern 10-25wt%, phosphoric acid 0-5wt%, and ferrous sulphate 0-5wt%. The method includes the following steps: mixing the constituents, pouring slurry into pattern for molding, taking natural solidification to the molded products. The invention could save energy, and is environment protection. It has the advantages of simple technology, and low cost.

Description

Burning-free ceramic product and preparation method thereof

Technical field

The present invention relates to a kind of ceramic and preparation method thereof, relate in particular to a kind of baking-free ceramic handicraft and preparation method thereof.

Background technology

The ceramic that people were familiar with generally needs in its making processes through high temperature sintering, its complex manufacturing technology, and need to consume certain energy, thereby its production cost is higher, and environment is polluted.

Summary of the invention

For a change the traditional ceramics goods must pass through the preparation method that high temperature burns till, and the invention provides a kind of preparation method of burning-free ceramic product.

The present invention is achieved in that a kind of burning-free ceramic product is (% by weight) composed of the following components:

Sand 10～30% clays 5～15%

Cement 5～15% cream 5～10%

Magnesium oxide 20～40% bittern 10～25%

Phosphoric acid 0～5% ferrous sulfate 0～5%

The preparation method of burning-free ceramic product of the present invention is:

(1), described each component is prepared burden in proportion, mix then and stirred 4～8 minutes, practice and make mud;

(2), with in the mud injection technology product mould, after 3 hours, get final product stripping forming;

(3), with the handicraft spontaneous curing at normal temperatures of institute's injection moulding.

In the component of the present invention, the diameter of sand is that 0.5～5mm, clay are that 10～250 orders, gypsum are that 120～220 orders, cement are that label is not less than No. 500, bittern is the byproduct that preparing salt by working up seawater produced, and its main component is a magnesium chloride solution, and its salinity is not less than 20 degree.

Baking-free ceramic is a kind of porcelain that coagulates, make by multiple inanimate matter synthetic natural mineral matter and other inanimate matter weighting material, its one-tenth porcelain principle is that the gelling initiator in the material prescription causes jelling agent at normal temperatures, then by a series of chemical reaction, gel is cross-linked with each other in inorganic filler, forms pottery through spontaneous curing.The intensity of pottery strengthens with the prolongation of set time, reaches firm degree at last.

Sand and clay are skeletons in each component of the present invention, and gypsum is a quick dry agent, and cement and magnesium oxide play solidification, and bittern is comprehensive gelifying agent, and phosphoric acid and ferrous sulfate play the mediation effect.

The present invention can be widely used in landscape art and technology is display pottery, architectural pottery, finishing material etc.Because goods need not to fire, and can save a large amount of energy; Thereby has an advantage of energy-conserving and environment-protective; Starting material are obtained easily again, and manufacture craft is simple, and cost is lower.Made goods through degradable behind the certain hour, have the advantage of environmental protection under physical environment.
