Abstract
A composite titanium pigment consists of titanium pigment 20-70 wt%, kaolin 1-2 wt%, ZnO 0.1-0.5 wt%, brightener 0.1-0.05(OB) wt% and heavy calcium carbonate. It's stable, has excellent whiteness, coloring and covering powers and better heat, light and weather resistances. It can be used as fillers in indoor and outdoor.
Description
Technical field
The present invention relates to chemical filler, specifically is a kind of white composite titanium dioxide that is widely used in products such as coating, paint, printing ink, papermaking, plastics, rubber, material of construction.
Technical background
Titanium dioxide (TiO2), zinc sulfide white (ZnS.BaSO4) are trickle white powder, have good tinting strength and opacifying power, in products such as coating, paint, printing ink, papermaking, plastics, rubber, material of construction, be widely used, but product will overcome the environmental pollution that brings in a lot of raw material production flow processs in process of production, for example: to sewage handling problem, thereby at present the market value of titanium dioxide and zinc sulfide white is higher in zinc sulfide white, the production process of titanium pigment.In order to reduce cost, though have in the prior art with other material compound zinc sulfide white or compound titanium dioxide often result of use now relatively to differ from many with titanium dioxide or zinc sulfide white, in the batching such as the disclosed composite titanium dioxide of CN1052127 a large amount of adding wollastonite, because the wollastonite impurity ratio is higher, the product whiteness that obtains is not enough, opacifying property relatively poor, and can blackening under acidic conditions.
Summary of the invention
The purpose of this invention is to provide the suitable and good weatherability of a kind of performance and titanium dioxide, meet not blackening of sulfiding gas, the composite titanium dioxide that cost decreases.
The technical scheme of Cai Yonging is so for achieving the above object, and a kind of composite titanium dioxide is characterized in that: be made up of following substances in percentage by weight:
Titanium dioxide 20%-70%, kaolin 1%-2%, ZnO (zinc oxide) 0.1%0-0.5%, whitening agent 0.1%-0.05% (OB), surplus are coarse whiting (water-ground limestone).
Kaolin has high whiteness, low sticking concentration and thin granularity, weathering resistance good stability; Coarse whiting is the natural pulverizing system of ore, good stability, and the whiteness that adds zinc oxide and whitening agent time product is better, has improved tint permanence and opacifying property.
The technological process of production of composite titanium dioxide of the present invention: with selected powder thorough mixing in proportion, to the powder high speed shear, temperature is controlled at 20 ℃-35 ℃, makes powder advance to draw the zwitterion combination by whirlwind pulverizer, and the cooling powder stores, packing promptly gets product.
Embodiment
Embodiment 1 composite titanium dioxide powder component 1
Titanium dioxide 40%, kaolin 2%, ZnO (zinc oxide) 0.5%, whitening agent (OB) 0.1%, surplus are coarse whiting.
Embodiment 2 composite titanium dioxide powder components 2
Titanium dioxide 30%, kaolin 2%, ZnO (zinc oxide) 0.5%, whitening agent (OB) 0.08%, surplus are coarse whiting.
Embodiment 3 composite titanium dioxide powder components 3
Titanium dioxide 60%, kaolin 2%, ZnO (zinc oxide) 0.5%, whitening agent (OB) 0.08%, surplus are coarse whiting.
Embodiment 4: experiment relatively
The composite titanium dioxide of embodiment 1 is compared with zinc sulfide white and titanium dioxide respectively
In above tabulation, the opacifying power of composite titanium dioxide product of the present invention also is similar to titanium dioxide greater than the opacifying power of zinc sulfide white, produce the zinc sulfide white of equal quality, cost is produced the quality of approximate titanium dioxide than the economic 200-400 of zinc sulfide white unit/ton, and cost is than the economic 1000-2000 of titanium dioxide unit/ton.
That this product also has is heat-resisting, the characteristics of light resistance, good weatherability, is applicable to indoor, outdoor filler.
Claims (1)
