Abstract
The present invention discloses a surface-modified titanium dioxide pigment, which comprises the following components by weight: 100 parts of titanium dioxide, 5-12 parts of bentonite, 2-7 parts of aluminum oxide, 3-6 parts of calcium sulfate, 2-20 parts of short oil alkyd and 1-5 parts of methanol. According to the invention, trace methanol is introduced as a polar solvent to promote the formation of a bentonite and titanium dioxide colloidal system; the compounding of aluminum oxide and calcium sulfate conducts adsorption-type surface treatment is in favor of light stability of the pigment; short oil alkyd can prevent re-agglomeration of the pigment, and is conducive to spread, thereby improving the dispersion and tinting strength of the titanium dioxide.
Description
Technical field
The invention belongs to technical field of chemistry and chemical engineering, particularly relate to the modified formula technology of titanium dioxide white pigment.
Background technology
Pigment, as the coloring matter decorated and protect, can be applied in each fields such as ink, plastics, rubber, coating, papermaking with dispersion state.White opaque pigment is based on titanium pigment, and excellent is important selection with R type titanium dioxide.But titanium dioxide light stability difference common is at present easy to change, disperse bad in solvent dispersion simultaneously, and pulverize easily caking, tinting strength and opacifying power need to improve.
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing and deficiency, the object of this invention is to provide a kind of surface-modified titanium dioxide pigment, be applied in coating and obviously can improve its rheology in coating solution and improve its dispersing property, its light stability is stronger simultaneously, has higher weathering resistance.
Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of surface-modified titanium dioxide pigment, comprises following component according to massfraction:
Titanium dioxide 100 parts;
Wilkinite 5 ~ 12 parts;
Aluminium sesquioxide 2 ~ 7 parts;
3 ~ 6 parts, calcium sulfate;
Short oil alkyd 2 ~ 20 parts;
Methyl alcohol 1 ~ 5 part.
As preferably, described titanium dioxide is Rutile type Titanium Dioxide.
As preferably, wilkinite SD-210 part, 5 parts, aluminium sesquioxide powder, 5 parts, calcium sulfate, short oil alkyd 12 parts, methyl alcohol 2 parts.
Beneficial effect: compared with prior art, the present invention has the following advantages: methyl alcohol carries out trace as polar solvent and introduces the formation that can impel wilkinite and titanium dioxide colloidal dispersion, simultaneously the compound of aluminium sesquioxide and calcium sulfate carries out to titanium dioxide the light stability that adsorption type surface treatment is conducive to pigment, short oil alkyd is then as preventing pigment from again luming, be beneficial to dispersion, thus improve dispersiveness and the tinting strength of titanium dioxide.
Embodiment
Below in conjunction with specific embodiment, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
Embodiment 1
First in the Rutile type Titanium Dioxide of 100 weight parts, add the solvent of 25 parts, usual selection water and high-speed stirring dispersion formed slurry, then input 10 parts of wilkinite SD-2 and 5 part aluminium sesquioxides and 5 parts of calcium sulfate stir, finally drop into the short oil alkyd of 12 parts and the methyl alcohol of 2 parts, after stirring reaction 2h, through filter pulp, and naturally dry or dry at 40 ~ 60 DEG C, final drying abrasive dust.
Embodiment 2
First in the Rutile type Titanium Dioxide of 100 weight parts, add the solvent of 40 parts, usual selection water and high-speed stirring dispersion formed slurry, then input 12 parts of wilkinite SD-2 and 3 part aluminium sesquioxides and 5 parts of calcium sulfate stir, finally drop into the short oil alkyd of 5 parts and the methyl alcohol of 2 parts, after stirring reaction 2h, through filter pulp, and naturally dry or dry at 40 ~ 60 DEG C, final drying abrasive dust.
