Abstract
The invention discloses a preparation method for kaolin/iron oxide black composite pigment. According to the method, iron oxide black prepared by using a sodium hydroxide oxidation process is utilized; an undried iron oxide black filter cake is directly used, 4 to 8% of calcined kaolin and 0.5 to 0.8% of ferrocene are added, and grinding at a high speed of 2000 to 3000 rpm is carried out for 10 to 15 min; powder obtained after grinding is taken out and dried, then a proper amount of water is added, and beating is carried out for 15 to 25 min so as to obtain slurry with a concentration of 50 to 60%; then urotropine, sodium metasilicate and polyethylene glycol respectively accounting for 0.1 to 0.2%, 0.2 to 0.3% and 0.2 to 0.3% of the slurry are added, and stirring is carried out for 20 to 25 min; and then grinding with a colloid mill is carried out until a particle size is less than 50 mu m, and drying and powderizing are carried out so as to obtain a finished product. Through addition of calcined kaolin into iron oxide black for grinding, the characteristic of acid resistance of kaolin is fully utilized, iron oxide black is allowed to be used in an acidic condition and to have the characteristic of acid resistance; so the use value of iron oxide black is improved.
Description
Technical field
The preparation method who the present invention relates to a kind of kaolin/iron oxide black composite pigment, belongs to chemical color field.
Background technology
Iron pigment is as important inorganic color(ed)pigment, and its annual production occupies first of inorganic color(ed)pigment.Due to the reinforcement of world's environmental consciousness, inorganic iron series pigments constantly replaces plumbous series, the serial poisonous mineral dyes of chromium such as pigment dyestuff and red lead, lead-chrome yellow with its feature such as nontoxic, odorless, pollution-free.Iron oxide black is because chemical composition is simple, nontoxic pollution-free, and chemical stability is strong, is widely used in building trade paint.But the over-all properties of existing domestic iron oxide black is poor, thereby limited the use range of iron oxide black.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of preparation method of kaolin/iron oxide black composite pigment is provided.The iron oxide black high thermal resistance that the method is produced is good, and strong covering power is dispersed superior.
The technical solution used in the present invention is as follows:
A kind of preparation method of kaolin/iron oxide black composite pigment, the iron oxide black that adopts sodium hydroxide oxidation style to make, directly use the oxidation filter cake of not drying, add and be equivalent to the calcined kaolin of iron oxide black filter cake weight 4-8% and the ferrocene of 0.5-0.8%, 2000-3000rpm speed lapping 10-15 minute, after taking out oven dry, add appropriate water making beating 15-25 minute, make the slurries that concentration is 50-60%, and add the urotropine of slurry weight 0.1-0.2%, the Starso of 0.2-0.3%, the polyoxyethylene glycol of 0.2-0.3%, stir 20-25 minute, by colloidal mill defibrination to particle diameter, be less than 50 μ m again, dry and beat powder, be finished product.
Beneficial effect of the present invention:
The present invention has added calcined kaolin and has ground in iron oxide black, makes full use of kaolinic acid-resistant property, can expand iron oxide black and be used in acidic conditions occasion, makes iron oxide black have acid-resistant property, has improved its use value.
The black iron oxide pigment that the present invention produces has superior heat resistance, well the feature such as resistance to acids and bases, weathering resistance and light absorptive is strong, tinting strength is high, strong covering power, consistency are good, good dispersity.
Embodiment
A kind of preparation method of kaolin/iron oxide black composite pigment, the iron oxide black that adopts sodium hydroxide oxidation style to make, directly use the oxidation filter cake of not drying, add and be equivalent to the calcined kaolin of iron oxide black filter cake weight 5% and 0.6% ferrocene, 3000rpm speed lapping 10 minutes, after taking out oven dry, add appropriate water making beating 20 minutes, make concentration and be 55% slurries, and add the urotropine of slurry weight 0.15%, the Starso of 0.2-%, 0.3% polyoxyethylene glycol, stir 25 minutes, by colloidal mill defibrination to particle diameter, be less than 50 μ m again, dry and beat powder, be finished product.
The present invention has added calcined kaolin and has ground in iron oxide black, makes full use of kaolinic acid-resistant property, can expand iron oxide black and be used in acidic conditions occasion, makes iron oxide black have acid-resistant property, has improved its use value.
The iron oxide black product performance analysis data that the present embodiment is produced is as following table:
| Project | Index | Detected result |
| Fe 2O 3Content (%) | ≥85 | 89.3 |
| 105 ℃ of volatile matters (%) | ≤1.0 | 0.77 |
| Oil number (%) | 15-25 | 22.5 |
| Tinctorial strength (%) | 95-105 | 97.9 |
| Resistance to 200 ℃/30min (△ E) | ≤1.0 | 0.76 |
