Abstract

The invention discloses a preparation method of composite titanium dioxide pigment with wollastonite coated with titanium dioxide. The preparation method includes following steps: (1), performing surface pretreatment on wollastonite, and wetting titanium dioxide for surface pretreatment; (2), adding wollastonite powder and titanium dioxide into a high-speed stirrer, and mixing sufficiently; (3), utilizing a wet-type grinder for grinding, and performing envelope treatment on the wollastonite powder and titanium dioxide after being mixed; (4), using a plate-and-frame filter press to filter-press ground paste, and subjecting an obtained filter cake to water washing; (5), drying; (6), crushing. By the preparation method, whiteness is improved without lowering using effects like covering power of titanium dioxide, using cost can be lowered substantially, and sedimentation in the previous process of solely using wollastonite to replace titanium dioxide is avoided.

Description

A kind of manufacture method of the composite titanium dioxide pigment of titanium white cladding wollastonite
Technical field
The present invention relates to chemical field, more specifically to a kind of titanium dioxide peplos covering method.
Background technology
Presently disclosed composite titanium dioxide production technology is mainly coated with triple superphosphate, fine particle calcium carbonate etc. as core, Application No. The patent of CN89108819.9 discloses a kind of method of use wollastonite composite titanium dioxide, its mainly by TiO2, CaSiO3, ZnO, AL2O3 and silane coupler are constituted, and above-mentioned raw materials is simply mixed and be uniformly composite titanium dioxide, and production technology is simple and crude, cladding Not exclusively, using effect is poor, high cost.
The content of the invention
In order to solve that existing composite titanium dioxide is present it is above-mentioned the problems such as, the invention provides a kind of titanium white cladding wollastonite Composite titanium dioxide pigment manufacture method.
The technical scheme that adopted for achieving the above object of the present invention is：A kind of titanium white coats the composite titanium dioxide of wollastonite The manufacture method of pigment, comprises the following steps：
（1）, the wollastonite for meeting predetermined particle diameter carried out into surface preparation, ready titanium dioxide moistening is carried out into surface and is located in advance Reason；
（2）, wollastonite in powder and titanium dioxide added in homogenizer, be sufficiently mixed, homogenizer mixing speed is 50-300rpm, heating-up temperature is 20-90 DEG C, and the response time is 8-60min；
（3）, using controlling wet-type finishing machine grind, while carrying out peplos process to mixed wollastonite in powder and titanium dioxide：Using super Thin wollastonite particle is core, adds dispersant and coloring agent, and peplos, milling time 2- are carried out as covering with titanium dioxide 50min；
（4）, to grind slurry filter press filter pressing, the filter cake for obtaining is washed；
（5）, drying；
（6）It is broken.
The step（1）In, wollastonite carry out inorganic agent used by surface preparation for silane coupling agent by quality percentage Number meter, consumption is 0-3%；It is silane coupling agent that titanium dioxide moistening carries out inorganic agent used by surface preparation, by weight percent Meter consumption is 0-3%.
The step（3）In the mean diameter of ultra-fine wollastonite be 2-90 μm, ultra-fine wollastonite by mass percentage Consumption is 20-69%.
The step（3）In, it is 20-80% that titanium dioxide consumption used is coated by mass percentage.
The step（3）In, coloring agent is chemical method Zinc Oxide, and by mass percentage consumption is 3-19%；Dispersant is molten Liquid is sodium hexameta phosphate, and by mass percentage consumption is 0.5-8%.
The step（3）In, titanium white powder content is 200-600g/L in titanium dioxide and wollastonite in powder slurry；Titanium dioxide and silicon Wollastonite in powder content is 200-600g/L in limestone flour slurry.
The manufacture method of the composite titanium dioxide pigment of the titanium white cladding wollastonite of the present invention, is not reducing titanium dioxide covering power Simultaneously and in the case of improving whiteness, use cost can be greatly reduced, while silicon is used alone before avoiding etc. using effect Lime stone point substitutes the sedimentation phenomenon produced during titanium dioxide.
Specific embodiment
The manufacture method of the composite titanium dioxide pigment of the titanium white cladding wollastonite of the present invention, comprises the following steps：
（1）, the wollastonite for meeting predetermined particle diameter carried out into surface preparation, ready titanium dioxide moistening is carried out into surface and is located in advance Reason, wollastonite carry out inorganic agent used by surface preparation for silane coupling agent by mass percentage, consumption is 0-3%；Titanium white It is silane coupling agent that powder moistening carries out inorganic agent used by surface preparation, and by mass percentage consumption is 0-3%；
（2）, wollastonite in powder and titanium dioxide added in homogenizer, be sufficiently mixed, wollastonite, the skill of titanium dioxide mixing Art condition is：Homogenizer mixing speed is 50-300rpm, and heating-up temperature is 20-90 DEG C, and the response time is 8-60min；
（3）, using controlling wet-type finishing machine grind, while carrying out peplos process to mixed wollastonite in powder and titanium dioxide：Using super Thin wollastonite particle is core, adds dispersant and coloring agent, and peplos, wollastonite base material peplos are carried out as covering with titanium dioxide Technical conditions be milling time 2-50min, the mean diameter of ultra-fine wollastonite is 2-90 μm, by mass percentage ultra-fine silicon Lime stone consumption is 20-69%, and it is 20-80% that titanium dioxide consumption used is coated by mass percentage, and coloring agent is chemical method oxygen Change zinc, by mass percentage consumption is 3-19%；Dispersant solution is sodium hexameta phosphate, and by mass percentage consumption is Titanium white powder content is 200-600g/L in 0.5-8%, titanium dioxide and wollastonite in powder slurry；Silicon in titanium dioxide and wollastonite in powder slurry Lime stone powder content is 200-600g/L；
（4）, to grind slurry filter press filter pressing, the filter cake for obtaining is washed；
（5）, drying；
（6）It is broken, that is, obtain composite titanium dioxide.
When wet grinding is carried out to titanium dioxide and wollastonite slurry, by the titanium dioxide, wollastonite slurry and dispersant Mixing is ground simultaneously, can be prevented effectively from titanium dioxide and wollastonite slurry and flocculation caking phenomenon is produced in pulping process. Can with titanium dioxide be profit effectively that wollastonite carries out peplos process using this method, obtain the composite titanium dioxide of excellent performance.
