Abstract
The invention discloses titanium dioxide pigment containing a composite high-molecular polymer. The titanium dioxide pigment comprises the following components in parts by mass: 100 parts of titanium dioxide, 5-12 parts of bentonite, 2-7 parts of aluminum oxide, 5-15 parts of polyester polymers, 1-3 parts of a wetting agent, 1-12 parts of amide compounds and 1-5 parts of methanol. If the titanium dioxide pigment is applied to a coating, the rheologic state of the titanium dioxide pigment in a coating solution can be remarkably improved, the dispersibility of the titanium dioxide pigment can be improved, and meanwhile the titanium dioxide pigment is stronger in light stability and higher in weather resistance.
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 titanium white powder pigment of compound macromolecular polymer, 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 titanium white powder pigment of compound macromolecular polymer, comprises following component according to massfraction:
Titanium dioxide 100 parts;
Wilkinite 5 ~ 12 parts;
Aluminium sesquioxide 2 ~ 7 parts;
Polyester polymers 5 ~ 15 parts;
Wetting agent 1 ~ 3 part;
Amide compound 1 ~ 12 part;
Methyl alcohol 1 ~ 5 part.
As preferably, described polyester polymers is polyethylene, polyvinyl chloride, or the multipolymer of polyethylene and vinyl acetate between to for plastic.
As preferably, described wetting agent is naphthenic acid zinc salt, sodium laurylsulfonate or dodecyl stearate.
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 aluminium sesquioxide carries out to titanium dioxide the light stability that adsorption type surface treatment is conducive to pigment, the introducing of acid or alkali formula polyester polymers surface of pigments can form the charge adsorption thicker coating layer of formation thus the stronger dispersion agent of conduct and anti-flocculation agent again, amide compound and wetting agent and titanium dioxide surface generation organic adsorption can prevent 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, the water of 25 parts is added and high-speed stirring dispersion forms slurry, then drop into 10 parts of wilkinite SD-2 and 5 part aluminium sesquioxides and stir, finally drop into the methyl alcohol of the naphthenic acid zinc salt wetting agent of 2 parts, 5 polyethylene, 5 parts of acrylamides and 2 parts, after stirring reaction 2h, through filter pulp, and naturally dry or dry at 40 ~ 60 DEG C, final drying abrasive dust.This product color is even, in bulky powder shape, has smooth fluffy sense.Sprayed on phosphatization plate by product, coating thickness controls at 50 ~ 70 microns, and then through resistance to artificial weathering test (GB/T1865-1997) 1000h, variable color is less than 2 grades, and loss of gloss is less than 1 grade, and without efflorescence, foaming, cracking or peeling phenomenon.
