CN102531380B - Gold-free golden-red agent and preparation method thereof - Google Patents

Abstract

The invention relates to a gold-free golden-red agent and a preparation method thereof. The gold-free golden-red agent is used for replacing the existing pigment using gold, novel technology and new formula are adopted, and the new formula includes producing the gold-free golden-red agent according to right proportion of zirconium fluoride, silicon oxide, silver carbonate, rubidium oxide, neodymium oxide, yttrium oxide and kaolin. Color and physicochemical indexes of produced products are the same as gold-containing products, price of the products is remarkably reduced, the products are nonhazardous and pollution-free, and the gold-free golden-free agent is beneficial for environment protection and physical and mental health of people and has good economic benefit and social benefit.

Description

A kind of no golden red toner and preparation method thereof

Technical field

The present invention relates to pottery and glass and use the pigment technology field, relate in particular to a kind of no golden red toner and preparation method thereof.

Background technology

Continuous development along with pottery and glass industry, it is single that pottery and glassy product have been broken away from kind, pattern is dull and formed comparatively complete product system, in pottery or glassy product production process, use different pigment can produce colourful product, pigment is for the ceramic marble paper printing, flat stamping wire mark pigment, and the starting material that adopt during pigment ratio directly influence its cost.

The general gold that adopts is made violet pigment in pottery and glass material at present, as everyone knows, gold is one of metal rare, the most most precious in the metal, because a large amount of uses of gold, its natural storage capacity is very deficient, and it is also very expensive to use gold to do its cost of raw material, how to reduce cost, substituting the problem that prior art adopts gold to make violet pigment in pottery and glass material, is the problem that the present invention need solve.

There is defective in prior art, haves much room for improvement.

Summary of the invention

The objective of the invention is, the problem that exists at prior art provides a kind of no golden red toner and preparation method thereof, has solved prior art and has used gold to make the high problem of the existing cost of violet pigment.

Technical scheme of the present invention is as follows: a kind of no golden red toner is characterized in that: described golden red toner component raw material weight per distribution ratio is:

Zirconium tetrafluoride 45%～60%

Silicon oxide 15%～30%

Silver carbonate 5%～10%

Rubidium oxide 1%～2%

Neodymium trioxide 0.2%～1%

Yttrium oxide 1%～3%

Kaolin 10%～20%

Wherein: described golden red toner component raw material weight per distribution ratio is: Zirconium tetrafluoride 52%, silicon oxide 25%, silver carbonate 9%, rubidium oxide 2%, Neodymium trioxide 1%, yttrium oxide 1% and kaolin 10%.

A kind of preparation method who does not have the golden red toner is characterized in that: described method comprises the steps:

A, batching, described batching are pressed column weight amount per-cent and are prepared:

Zirconium tetrafluoride 45%～60%

Silicon oxide 15%～30%

Silver carbonate 5%～10%

Rubidium oxide 1%～2%

Neodymium trioxide 0.2%～1%

Yttrium oxide 1%～3%

Kaolin 10%～20%

B,To mix behind the described batching crushing screening, get 100 parts of described batchings and place ball mill to add water to make slip for 60 parts, ball milling to 250 order, screenings is less than 0.1%;

C,With the slip behind ball milling oven dry and beat more than powder to 100 order, place gas fired kiln under 1250～1350 ℃ of high temperature weakly reducing atmospheres or place the electric furnace temperature to control under 1250～1350 ℃ of neutral atmospheres, to burn till, soaking time is 4.5～5.5 hours.

Beneficial effect of the present invention is: after the present invention adopts technique scheme; there not to be the pigment that the golden red toner substitutes existing employing gold; owing to adopted new prescription novel process; make product quality and physical and chemical index identical with the product that contains golden pigment; reduced product price significantly; and toxicological harmless is pollution-free, and environment protection and people's physical and mental health has all been brought very big benefit, has good economic benefit and social benefit.

Embodiment

The invention provides a kind of no golden red toner and preparation method thereof, by adopting new prescription, utilize the correct proportioning of raw materials such as Zirconium tetrafluoride, silicon oxide and silver to make batching be purple, and do not contain the golden red toner of gold component by the preparation of rational production technique, solve prior art and used gold to make the high problem of the existing cost of violet pigment.

For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, the present invention is described in more detail by the following examples.

Table 1

It is as follows that the present invention does not have golden red toner preparation method:

According to the prescription of table 1, component raw material is prepared burden by weight percentage in the table 1, and described raw material is carried out weighing, mixes behind the crushing screening;

(1) batching in the table 1 is placed ball mill by 100 parts of weight and adds water make slip for 60 parts, ball milling to 250 order, screenings is less than 0.1%;

(2) slip behind the ball milling is dried and beaten more than powder to 100 order, place gas fired kiln under 1250～1350 ℃ of high temperature weakly reducing atmospheres, to burn till, optimum temps control is at 1300 ℃ or place the control of electric furnace temperature to burn till under 1250～1350 ℃ of neutral atmospheres, optimum temps control is at 1280 ℃, soaking time is 4.5～5.5 hours, and best soaking time is 5 hours.

It should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
