technical field

The present invention relates to a kind of iron oxide pigment, be specifically related to a kind of ferric oxide red colorant containing sericite in powder and preparation method thereof.

Background technology

Iron oxide pigment is the widely used mineral dye of a class, in building, coating, ink, pottery, in the industries such as makeup, widely apply, it is stable chemical performance not only, acid-fast alkali-proof, fast light heat-resisting, to dry wet, the tolerance level of the weathers such as fever and chills is high, also there is chromatogram wide, tinting strength is stronger, the nontoxic advantage such as inexpensive, the ferric oxide series pigment that existing market is used mainly contains red iron oxide, iron oxide black, iron oxide yellow and orange, palm fibre, the green composite pigment that waits, apply very extensive, but exist easily and reunite in actual use, difficult dispersed in medium, the problems such as color and luster is bright not, in order to obtain better use properties, often need iron oxide pigment to carry out surface treatment and improvement in performance, to improve production application performance, improve added value of product.

Summary of the invention

The object of the invention is to, a kind of ferric oxide red colorant containing sericite in powder is provided, to improve iron oxide red intensity and toughness, improve the quality of products, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of ferric oxide red colorant containing sericite in powder, it is characterized in that, pigment of the present invention is made up of the raw material of following weight part: red iron oxide 280-300, allyl polyglycol 2-3, aluminum magnesium silicate 2-3, glass fibre 6-8, sericite in powder 20-25, lanthanum trioxide 1-2, zirconium dioxide 3-4, dimethyl silicone oil 2-3, auxiliary agent 4-5.

Described auxiliary agent is made up of the raw material of following weight part: aluminium hydroxide 2-4, aminopropyl triethoxysilane 1-2, tamarind seed gum 0.5-1, pearlstone 10-12, Graphene 6-8, tetramethylolmethane 2-3, magnesium oxide 1-3, SODIUM PHOSPHATE, MONOBASIC 1-2, Starso 1-2; Preparation method first mixes tamarind seed gum, Starso, add appropriate water, be stirred to mixture and dissolve dispersion completely, add again subsequently other remaining component, after stirring, freeze-day with constant temperature 3-4h at 50-60 ℃, grinds to form 250-300 order powder by mixture after being dried, and to obtain final product.

Described a kind of ferric oxide red colorant containing sericite in powder, its preparation technology is:

(1) first red iron oxide is mixed with dimethyl silicone oil, after stirring, send into grinding in ball grinder 20-30min, cross 100-150 mesh sieve;

(2) will in allyl polyglycol, add appropriate water, be stirred to mixture and dissolve completely, add step (1) gained material and other remaining component, after mix and blend 25-30min, drying and processing under 50-60 ℃ of condition, ball milling 20-25min after drying, cross 250-300 mesh sieve, get product.

Beneficial effect of the present invention is: utilize allyl polyglycol, dimethyl-silicon wet goods raw material to improve iron oxide red dispersiveness, reduce agglomeration, again in conjunction with raw materials such as glass fibre, sericite in powder, zirconium dioxides, hardness and the toughness of ferric oxide red colorant are improved, wear-resisting weather-proof, and there is certain temperature resistant capability, ferric oxide red colorant outward appearance exquisiteness prepared by the present invention, in body material, be uniformly dispersed, color and luster is bright lasting, long service life can be widely used in multiple fields.
