Abstract

The invention relates to a ferric oxide pigment, and particularly relates to a flame retardant ferric oxide red pigment containing encapsulated red phosphorus. The red pigment is prepared from the following raw materials in parts by weight: 280-300 parts of iron oxide red, 2-3 parts of guar gum, 2-3 parts of hydroxypropyl methylcellulose, 2-4 parts of zinc stearate, 2-3 parts of sodium tripolyphosphate, 1-2 parts of titanate coupling agent, 2-4 parts of encapsulated red phosphorus, 10-12 parts of zeolite powder and 4-5 parts of additive. For producing the pigment, surface modification of iron oxide red powder is carried out by using guar gum, hydroxypropyl methylcellulose and sodium tripolyphosphate so that the powder has good surface activity and dispersibility, and then encapsulated red phosphorus, zeolite powder and zinc stearate are combined, so that the ferric oxide pigment prepared has excellent thermal stability, fire resistance, flame retardancy, is safe in use, and has uniform color, good covering and wide application range.

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 fire-retardant ferric oxide red colorant containing encapsulated red phosphorus is provided, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of fire-retardant ferric oxide red colorant containing encapsulated red phosphorus, 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, guar gum 2-3, Vltra tears 2-3, Zinic stearas 2-4, tripoly phosphate sodium STPP 2-3, titanate coupling agent 1-2, encapsulated red phosphorus 2-4, zeolite powder 10-12, 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 fire-retardant ferric oxide red colorant containing encapsulated red phosphorus, its preparation technology is:

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

(2) guar gum, Vltra tears, tripoly phosphate sodium STPP are mixed, add appropriate water, being stirred to mixture dissolves 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 the raw materials such as guar gum, Vltra tears, tripoly phosphate sodium STPP to the iron oxide red surface modification of having carried out, make this powder there is good surfactivity and dispersiveness, reduce the agglomeration between powder, promote the consistency of itself and body material, again in conjunction with raw materials such as encapsulated red phosphorus, zeolite powder, Zinic stearass, make ferric oxide red colorant prepared by the present invention also there is good thermostability, fire resistant flame retardant, use safer, and color and luster is even, opacifying power is good, has wide range of applications.
