Description

A kind of method that liquid phase high temperature and pressure cladding prepares heatproof iron oxide yellow
Technical field
The present invention relates to the sides that ferric oxide yellow pigment more particularly to a kind of liquid phase high temperature and pressure cladding prepare iron oxide yellow Method.
Background technology
Iron oxide yellow, also known as FeOOH, molecular formula are FeOOH or Fe2O3·H2O is in yellow powder, grain Sub- shape is needle-shaped, and it is environmentally friendly inorganic pigment, light resistance to have higher tinting strength, tinting power, covering power, and nontoxic Reach 6-7 grades.Ferric oxide yellow pigment is widely used in building materials, coating, paint, plastics, rubber, electronics, industrial catalyst, cigarette The industries such as grass, cosmetics.
Common iron oxide yellow surface is not coated, contained by the crystallization water be easy to lose at high temperature, to become Iron oxide red.It is mainly at present the technology coated under room temperature about the coating technology of ferric oxide yellow pigment, due under room temperature, Pigment particles often exist in a manner of reunion, also are difficult to by particle whole depolymerization, and just because of reunion grain by high-speed stirred The presence of son causes coating to cannot be introduced into all cladding faces, uneven so as to cause coating, and influences heat resistance.
Chinese invention patent application (the application number of applicant's application：CN201710154320.6 a kind of heat resistant type) is disclosed Ferric oxide yellow pigment and preparation method thereof, the composite material formed by trbasic zinc phosphate coated iron oxide Huang improve iron oxide yellow Heat resistance can be used when plastic processing and powdery paints are applied as colorant and preservative.But prepared by this method Iron oxide yellow is molded temperature tolerance can only be at 260 DEG C or so, and the cladding period of the common iron oxide yellow cladding process is longer, are 10- Or so 20 hours.
Invention content
The present invention coats non-uniform deficiency to solve ferric oxide yellow pigment, influences heat resistance, the present invention first Purpose is a kind of method that liquid phase high temperature and pressure cladding prepares iron oxide yellow, and this method is by being added glycerine, after capable of being dissolved in water It is attached to scattered iron oxide yellow surface, it is made to be not easy to reunite so that the cladding of aluminium is more uniform, in addition, passing through high temperature height It is only the 1/10-1/ in common iron oxide yellow cladding period that pressure reaction condition, which can promote the promotion of coating efficiency, cladding period, 5, further, the present invention improves iron oxide yellow heat resistance in one layer of compact aluminum oxide of iron oxide yellow outer cladding and zinc oxide film Energy.
In order to achieve the above purpose, present invention employs technical solutions below：
A kind of method that liquid phase high temperature and pressure cladding prepares iron oxide yellow, this method include the following steps：
1) the iron oxide yellow slurries made are placed in reaction kettle, open stirring, is slowly added to aluminum sulfate solution while stirring, so Afterwards in the feed liquid during glycerine and zinc carbonate addition reaction kettle is added, it is 11~12 to adjust material liquid pH value in reaction kettle, waits for pH After stabilization, reaction kettle cover is closed；The addition of the aluminum sulfate is the 40~60% of iron oxide yellow weight, and the addition of glycerine is The 1%~5% of iron oxide yellow weight, the addition of zinc carbonate are the 2~8% of iron oxide yellow weight；
2) it starts to warm up to 250 DEG C -300 DEG C, heating rate controls within per minute at 5~15 DEG C；When warm in reaction kettle After degree reaches 220-250 DEG C, into keeping warm mode, pressure control is in 2.2-4.0MPA, and heat preservation temperature difference control is within 5 DEG C；
3) after keeping the temperature 1-3 hours, heating power supply is closed, but be kept stirring, until kettle cover is opened after being cooled to 60 DEG C or less, It is 7.5~8.5 to be adjusted to pH, is rinsed, is filtered after pH stabilizations, 100-120 DEG C of drying finally crushes.
As a further improvement, the addition of the aluminum sulfate is the 45-55% of iron oxide yellow weight, the addition of glycerine It is the 1.6%~3.5% of iron oxide yellow weight, the addition of zinc carbonate is the 2.7~5.0% of iron oxide yellow weight.
As a further improvement, the mass percent concentration of the iron oxide yellow slurries is 8~15%；It will be prepared after preparing Good iron oxide yellow slurries, which are placed in high speed dispersion stirring, carries out dispersion stirring, and rotating speed is controlled in 500R/min, and jitter time is 30-40 minutes.
As a further improvement, the mass percent concentration of the aluminum sulfate be 15~25%, use content for The Al of 98.5% mass fraction2(SO4)3·16H2O, which is prepared, to be made.
As a further improvement, adjusting pH value, step using the NaoH solution of 10% mass fraction in the step 1) 3) pH value is adjusted using the dilute sulfuric acid of 10% mass fraction in.
The present invention is attached to scattered iron oxide yellow surface after capable of being dissolved in water, makes its group of being not easy by the way that glycerine is added It is poly- so that the cladding of aluminium is more uniform, and further, the present invention uses high temperature and pressure powder deploymerization and decentralization technology, passes through aluminium oxide The composite material formed with oxide coated by zinc iron oxide yellow improves the heat resistance of iron oxide yellow, can be applied in plastic processing and powder It is used as colorant and preservative when material application, simultaneous oxidation zinc can to a certain degree inhibit the red phase of later stage iron oxide yellow Generation so that color is purer.In addition, it is desirable to reach 260 DEG C or more of temperature tolerance, after common iron oxide yellow coats, cladding The percentage that object accounts for iron oxide yellow total amount reaches 20% or more, directly affects power part and the form and aspect of iron oxide yellow, and after this technique cladding, Coating accounting only 10% or so, power part higher, power part that difference is about 10% or so.The cladded type iron oxide that the present invention synthesizes Huang has heat resistance good, and cladding is more uniform, and synthetic method is simple, the cladding period is short, the only commonly 1/10- in cladding period 1/5, the advantages that at low cost, safety and environmental protection, there is higher industrial application value.
