Description

The manufacture method of blue inorganic pigment

The present invention relates to a kind of manufacture method of blue look mineral dye, mineral dye can be used as the tinting material of inorganic paint, plastics, rubber item, cement products and asbestos-cement products, artificial marble, mosaic goods, printing ink and high temperature ink etc., ceramic industry pigment, senior drawing pigment and advertisement poster pigment.

Current, abroad in fields such as plastics, rubber item, inorganic paint, high temperature ink, pottery and mosaic, all replace pigment dyestuff with mineral dye.Can not satisfy the demand because the natural inorganic pigment color is single, quantity is few, kind is few, therefore people are devoted to study artificial inorganic pigment in recent years, chemical manufacturing process as the current artificial inorganic pigment that generally adopts of China, its investment is big, complicated operation, three wastes public hazards are serious, and the price of product is also somewhat expensive.

Japan the 1st changes into industrial commercial firm and produces ultramarine, the employing solid reaction process is produced, with kaolin, alkali, Sulfur, reductive agent (charcoal, coal or rosin, rosin) is raw material, secluding air roasting 40-50 hour, 750 ℃-850 ℃ of maturing temperatures, 40-50 hour its combustion time, the heat resisting temperature of product is lower than 300 ℃, and this needs the industrial pigment of pyroprocessing for some, be inappropriate, the color of product has only orchid, purple blue.Need to seal in the reducing atmosphere stove with reductive agent, input and output material all will be taked special measure, the technology more complicated.

The objective of the invention is to propose a kind of production method of the new blue look mineral dye of production, to shorten to 1.5-3 hour from 40-50 hour combustion time, the heat resisting temperature of product is brought up to 900 ℃, technological process is more simplified, and the color of product can enlarge orchid, purple blue, day orchid, Hai Lan, Zang Lan etc.

Invention is achieved in that a kind of manufacture method of blue look mineral dye, by changing tinting material, catalyst consumption, the control maturing temperature, change and the control color with artificial synthesis, blue look mineral dye prescription (weight percent) is: kaolin: 30-65%, Xiao Suangu or other cobalt salt: 4-20%, zinc oxide: 10-40%, Sulfur: 5-20%, sodium salt or soda 0-20%, titanium oxide: 0-5%, adopt check, batching, batch mixing, roasting, grind, check, operations such as packing, synthetic and dyeing is merged into a step and carries out with pigment, and calcination atmosphere is an oxidizing atmosphere, maturing temperature 980-1080 ℃ ± 30 ℃, roasting soaking time 1.5-3 hour, grinding can be dry grinded or be passed through water or industrial spirit wet-milling, product granularity＜500 orders, and in particular cases granularity is less than 1000 orders or 1500 orders.

Adopt method of the present invention, have following characteristics:

1, the method that adopts solid state reaction and staining to combine is merged into a technical process to two technical process, simplifies technology, shortens flow process, saves time, and has improved production efficiency, and save energy reduces cost significantly.

2, main raw and processed materials is kaolin (Suzhou soil, a china clay), and reserves are big, distribution is wide, low price.

3, do not have pollution problem such as the three wastes in the production technique, the equipment that needs is few, does not have waste product basically.

4, product can reach following index through check:

A, cover ratio (black and white square method): 30-35m ²/ kg

B, granularity≤500 orders (particular requirement≤1000 orders or 1500 orders)

C, acid corrosion-resistant performance: soak nondiscoloration in 100 hours in 5% aqueous hydrochloric acid

D, alkali corrosion resistance performance: soak in 5% sodium hydroxide solution and do not change in 100 hours

E, resistance to light: the nondiscoloration in 150 hours of 500w intensive ultraviolet light irradiation

F, resistance toheat: be heated to nondiscoloration in 900 ℃/65 hours in the atmosphere, do not decompose.

G, water insoluble soaks in tap water and did not dissolve nondiscoloration in 100 days.

5, the mineral dye that adopts the inventive method to produce is compared with international like product, and good product performance, price have only external 1/2.Compare with home products, 200 ℃ of the blue or green blue heat resisting temperatures of phthalein, poisonous in the blue production of zirconium vanadium, the big fire orchid costs an arm and a leg, generally than the expensive 50-250% of the present invention product.

Now sketch technical process of the present invention:

Technical process comprises check, batching, batch mixing, roasting, grinding, check, packing, warehouse-in supervisor.The content of slubbing inspection process is: the quality of various raw materials, its purity are technical pures or are better than technical pure that granularity is less than 320 orders.In particular cases, granularity is less than 1000 orders or 1500 orders.

Prescription in the batching is: kaolin: 30-65%, Xiao Suangu (or other cobalt salt): 4-2%, zinc oxide: 10-40%, Sulfur: 5-20%, sodium salt (soda): 0-20%, titanium oxide: 0-5%.Wherein kaolin is 1 grade of product, and zinc oxide is that technical pure (ZnO content＞97%) titanium oxide is sharp titanium technical pure (TiO ₂Content＞98%), Sulfur is a technical pure, and sodium salt or soda are technical pure, and Xiao Suangu (or other cobalt salt) is a technical pure, and except that the big component of consumption, the weight of other composition will claim accurate to 1/100 gram in the batching.

Xiao Suangu among the present invention (or other cobalt salt) is main tinting material, and consumption is bigger, and blue look dark is more, and cost also can strengthen, and generally is controlled at below 20%.Aluminum oxide composition in the kaolin is a tinting material, and its content size is also very big to blue look influence, and content is big purple partially blue, and the little inclined to one side sky of content is blue.Other composition is a carrier, and granularity more better.The then blue colour cast of titanium oxide tinting material consumption increase is to purple blue.The Zinc oxide coloring agent increases blue colour cast to the sky orchid with consumption.Sulfur and sodium salt (or soda) play katalysis, and controls reaction speed is also influential to color simultaneously, and along with consumption increases, blue colour cast is to Zang Lan or Hai Lan.

Maturing temperature is higher, and blue colour cast is to purple blue, and maturing temperature is on the low side, and blue colour cast is to sky blue.

Embodiment 1: kaolin 43.5%, and Xiao Suangu 10%, zinc oxide 35%, Sulfur 10%, salt 1%, titanium oxide 0.5%, in the porcelain crucible of packing into behind the mixing, roasting 1000 ℃/2 hours obtains sky blue pigment.

Embodiment 2: kaolin 50%, rose vitriol 6%, zinc oxide 25%, Sulfur 8%, caustic soda 8%, titanium oxide 3%, be mixed even after, in the porcelain crucible of packing into, roasting 1080 ℃/1.5 hours obtains purple blue pigment.

Embodiment 3: kaolin 48%, and Xiao Suangu 12%, zinc oxide 15%, Sulfur 6%, soda ash 18%, titanium oxide 1%, in the porcelain crucible of packing into after mixing, roasting 1060 ℃/2.5 hours obtains Zang Lan.

Real hedge example 4: kaolin 42.5%, Xiao Suangu 8%, zinc oxide 20%, Sulfur 16%, salt 12%, titanium oxide 1.5%, in the porcelain crucible of packing into after mixing, roasting 1040 ℃/3 hours obtains extra large blue pigment.
