The method comprises the following raw materials in percentage by weight: main materials include 90-97% of ceramic frits and 3-10% of kaolin; an additive is nano silicon which is 0.5-4% of the total weight of the main materials; an auxiliary additive includes ethanol which is 1-5% of the total weight of the main materials and CMC (Sodium Carboxy Methyl Cellulose) which is 0.01-0.05% of the total weight of the main materials; and water is 47-50% of the total weight of the main materials. The proportion of large ball stones to medium ball stones to small ball stones of a ball mill is 2:3:5; the proportion of the materials to the balls to the water is 1:2:0.5; the grinding time is 40-60 h; the fineness of the glaze slurry is indicated through controlling remains of a 250-mesh screen within 0.01-0.03%; and the viscosity is 10-30 S by a TU-4 viscometer. The method comprises the steps of screening, removing iron, recycling for 3-5 times, storing and aging in a glaze barrel for 3-7 days, and screening and removing iron again before applying glaze. According to the method disclosed by the invention, the hardness and the abrasive resistance of the glaze are improved; the grinding time of the glaze is shortened; the energy consumption is saved; and the production cost is reduced.

Description

The preparation method of high-strength, high-anti-friction sclerotin enamel

 

Technical field:

The present invention relates to the Ceramic glaze preparation methods, specifically is a kind of preparation method of high-strength, high-anti-friction sclerotin enamel.

Background technology:

Conventional bone enamel burns that temperature is low, and glaze is softer, wears no resistance, scratched by hard things such as knives and forks easily, and easy soil pick-up, thereby influence cleaning and attractive in appearance causes the sclerotin porcelain low work-ing life.

Summary of the invention:

The present invention is intended to solve the problems referred to above that conventional bone ceramic glaze surface material exists, and a kind of preparation method of high-strength, high-anti-friction sclerotin enamel is provided.

The technical scheme that the present invention solves described problem employing is: a kind of preparation method of high-strength, high-anti-friction sclerotin enamel, comprise burden process, grinding step, iron removal step, wherein:

A. in the burden process, by weight percentage, major ingredient: preparing ceramic clinker 90-97, kaolin 3-10; Additive: the nano-silicon that accounts for major ingredient gross weight 0.5-4%; Supplementary additive: the ethanol and the CMC that accounts for major ingredient gross weight 0.01-0.05% that account for major ingredient gross weight 1-5%; Water: account for major ingredient gross weight 47-50%;

B. in the grinding step, ball mill ballstone ratio: big: in: little=2:3:5, material: ball: water=1:2:0.5, milling time: 40-60 hour, glaze slip fineness: the surplus 0.01-0.03% of 10000-hole sieve, viscosity: coating-4 viscosity meter 10-30S;

C. in the iron removal step, sieve except that ferrikinetics 3-5 time, the glaze bucket stores old 3-7 days, is sent to the glazing operation after detection glaze slip performance is qualified after screening out iron, last glazing.

Compared with prior art, increased the additive nano-silicon in the composition of raw materials of the present invention, and be supplementary additive with ethanol, CMC, improved sclerotin enamel material hardness and wear resistance thus, reduced the milling time of glaze simultaneously, energy efficient reduces production costs.The beginning that the present invention can also improve glaze is melted temperature, increases the thawing scope of glaze, has also improved the Gloss of Glazes degree simultaneously, makes glaze texture that change be arranged greatly.

Embodiment:

Below in conjunction with embodiment in detail the present invention is described in detail.

The preparation method of the high-strength, high-anti-friction sclerotin enamel that present embodiment provides, carry out as follows:

1. proportioning raw materials is pressed following weight percent meter:

Major ingredient: preparing ceramic clinker 97%, kaolin 3%;

Additive: the nano-silicon that accounts for major ingredient gross weight 2.25%;

Supplementary additive: account for the ethanol of major ingredient gross weight 3%, account for the CMC of major ingredient gross weight 0.01%;

Water: account for major ingredient gross weight 48%.

2. technology controlling and process:

Ball mill ballstone ratio: big: in: little=2:3:5;

Material: ball: water=1:2:0.5;

The glaze slip fineness: the 0.01-0.03%(10000-hole sieve is surplus);

Viscosity: coating-4 viscosity meter 10-30S.

3. technical process:

By proportioning raw materials above-mentioned major ingredient, additive, supplementary additive and water are gone into mill, ground 40-60 hour, and sieved except that ferrikinetics 3-5 time after the measurement fineness is qualified, the glaze bucket stores old 3-7 days, be sent to the glazing operation after detection glaze slip performance is qualified after screening out iron, last glazing.

4, effect comparison:

Title	Conventional bone enamel preparation method	The present invention
			Milling time	55-60 hour	48-50 hour
Hardness of glaze surface	466.59kg/mm 2	532.785 kg/mm 2
			Glaze sticking power	Generally	Good
Glossiness	94%	98%
			Thermostability	140 ℃ once do not split	150 ℃ once do not split

As seen from the above table, the sclerotin enamel that makes by preparation method of the present invention, obvious with the sclerotin enamel contrast effect that conventional bone enamel preparation method makes, glaze texture obviously improves, and hardness of glaze surface, intensity significantly improve, and the glaze appearance tactile impression is soft, milling time shortens, production technique is simple, and the glaze cost descends, and has reached energy saving purposes.
