Abstract
The invention discloses a modified production method for titanium dioxide pigment of composite high-molecular polymers. The method includes the steps of adding 10-50 parts of water to 100 parts of rutile type titanium dioxide to be evenly stirred into a sizing agent, sequentially adding 5-12 parts of bentonite SD-2, 5-15 parts of polyester polymers and 2-7 parts of aluminium oxide powder to be evenly stirred, sequentially adding 1-5 parts of methyl alcohol, 1-3 parts of wetting agent and 1-3 parts of chloridized propylene epoxide to be stirred and react for 0.5-2 h, and conducting filtering, stoving, drying and grinding. The titanium dioxide pigment is applied to paint, the rheology state of titanium dioxide pigment in a paint solution can be obviously improved, and the dispersion performance of titanium dioxide pigment can be improved; meanwhile, the light stability of titanium dioxide pigment is higher, and titanium dioxide pigment has higher 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 modified producing method 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 is by the following technical solutions: a kind of titanium white powder pigment modified producing method of compound macromolecular polymer, the water of 10 ~ 50 parts is added and the formation slurry that stirs in 100 parts of Rutile type Titanium Dioxides, then the wilkinite SD-2 of 5 ~ 12 parts is added successively, the polyester polymers of 5 ~ 15 parts, the aluminium sesquioxide powder of 2 ~ 7 parts also stirs, then the methyl alcohol of 1 ~ 5 part is added successively, the chlorination propylene oxide of the wetting agent of 1 ~ 3 part and 1 ~ 3 part, and stirring reaction 0.5 ~ 2h, eventually pass filtration, dry, drying and grinding, .
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.
