Description
Technical field
The present invention relates to a kind of low viscosity ferric oxide yellow pigment, and in particular to by controlling pressure in course of reaction, pH
The conditions such as value, temperature, reaction time prepare low viscosity iron oxide yellow.
Technical background
Iron oxide yellow, also known as FeOOH, its molecular formula are FeOOH or Fe2O3H2O, in yellow powder, its grain
Son is shaped as needle-like, with higher tinting strength, tinting power, covering power, and nontoxic, is environmentally friendly inorganic pigment, its light resistance
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 is different with surface chemistry due to particle shape, and its viscosity is higher, in coating application process
It is middle to there are problems that, it is spherical with other isometric systems such as iron oxide red, iron oxide black is compared for cube, iron oxide yellow
It is acicular texture, and the length-width ratio of its aciculiform is different.Because needle-like structures, cause iron oxide yellow and the iron oxide of isometric system
It is red to be compared with iron oxide black, with higher resistance to flow energy, so its viscosity highest in the coating system of most of media,
The problem of being also the maximum that coating and pigment industry are run into.
The rheological property of coating, from construction to film forming, all has strict demand, at this from beginning to end from production to storage
In a little stages, because the concentration of pigment is different, the shearing force that coating is subjected to is different with pressure, so viscosity or resistance to flow can be
One key technical index of coating, in the grinding stage of high shear force, in order that pigment content reaches peak in mill base, to the greatest extent
Amount improves production efficiency, it is desirable to which the viscosity for grinding base is lower, and its viscosity also is intended in the mixing of coating, transfer, packaging process
It is lower.
The all components of coating all have a certain impact to viscosity, and for the viscosity characteristicses required by acquisition, selection is suitable
Pigment is a key factor.The important development direction for being coating industry at present with high solids low volatile organic, and face
The viscosity of material determines the size of solid content, and pigment viscosity is too high, causes coating resistance to flow higher, totally unfavorable to producing.
There is ' one kind reduction oxidation of the Nantong Bao Ju pigment company issued patents number for ZL201310277999.X the current country
