Description
Technical field
The present invention relates to a kind of production technical field of white powder pigment, and in particular to one kind is with Calcium Carbonate and controlled micro crystallization
Glass dust is the composite white pigment of primary raw material Jing high-energy ball milling preparation technologies.
Background technology
Titanium dioxide has excellent covering power, reducing power, fineness and a weatherability, and its have chemical inertness, it is nontoxic,
The performance such as harmless, becomes the maximum Chinese white of most widely used at present and consumption figure.However, titanium white production and
What the factor such as limited of problem of environmental pollution that actual application causes and titanium dioxide resource limited titanium dioxide industry enters one
Step upgrading and development.The mainly powder surface that titanium dioxide works in actual applications, and the nuclear structure of powder body is not played
Effect.A kind of effective way for solving the problem is prepared and using titanium dioxide substitute products.
Described titanium dioxide succedaneum, refers to the performance with titanium dioxide and cost is the titanium dioxide bottom of than, being capable of part or complete
Portion substitutes the inorganic powder material that titanium dioxide is employed.From 20 century 70s, titanium dioxide succedaneum has just had started to research
And exploitation, and achieve good economic benefit.Inorganic particle/TiO2Composite powder material possesses core (inorganic particle)-shell
(TiO2) structure, it is the optimal replacement of titanium dioxide so far while possessing similar pigment performance and cheap to titanium dioxide
Product.
Composite titanium dioxide is produced using inorganic particle method for coating, it is different according to handling process, can be generally divided at present
Two kinds of dry and wet.
Dry method is usually that surface activation process is carried out to inorganic powder particle using mechanochemical method, causes zwitterion
With reference to.Mechanochemical method is a kind of efficient, energy-conservation and comparatively environmentally friendly powder preparation method.It is powder body system
The method that favor is enjoyed in standby technique, realizes to realize between inorganic particle and titanium dioxide effectively using Mechanochemical Effect
Cladding.Chinese invention patent document such as Publication No. CN101100561A is disclosed and adopts dry production, uses whirlwind pulverizer
To powder body high speed shear, at a certain temperature, make powder body introduce zwitterion and combine, obtain a kind of composite titanium dioxide.
Wet method is in a liquid state, by chemical assistant or mechanical lapping, to be combined two kinds of powder body covered composite yarns
Thing.If the Chinese invention patent document of Publication No. CN1724595A is to white mineral powder-TiO2The system of composite white pigment
It is standby, using by after inorganic mineral powder slurrying with TiO2Suspension realize with the help of chemical assistant chemical reaction coat,
Form complex.The Chinese invention patent document of Publication No. CN101775239A discloses a kind of with the inorganic of high covering power
The preparation of composite white pigment, is by adding certain auxiliary agent, in wet ultra-fine grinding by titanium dioxide and white mineral powder
Two kinds of powder body are combined in equipment obtain complex.But wet method preparation is higher to equipment requirements, and the composite granule performance of preparation is not
It is good, and to environment in production process.
The composite titanium based on Calcium Carbonate, pyrophillite, Kaolin and barite etc. prepared using mechanochemical method
White lead, with preferably covering power, but acid resistance is poor, and the surface soundness of coating, overlay film or paint film is poor.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides one kind is based on Calcium Carbonate and microcrystalline glass powder
Want the composite white pigment of raw material Jing high-energy ball milling preparation technologies.
A kind of composite white pigment, the composite white pigment is made up of following parts by weight ingredient：
By adopting above-mentioned technical proposal, there is provided a kind of whiteness height, strong covering power, the compound white of stable chemical performance
Pigment.The application adds clear glass micropowder, improves the hiding rare of composite white pigment, adds super fine, improves multiple
The compactness and weatherability on Chinese white surface are closed, is allowed to more stable.
The calcium carbonate fine powder grain diameter size is 325～2500 mesh, and Blue Whiteness value is 92～97.
The clear glass micro powder granule size is 325～2500 mesh, and Blue Whiteness value is 90～95, and described
700～900 DEG C of heat treatments of bright glass micro mist Jing realize its controlled micro crystallization.Present invention introduces the glass micro mist of controlled micro crystallization, changes biography
The relatively low defect of the covering power of the one-component calcium carbonate superfine powder powder body of system.After controlled micro crystallization, its refractive index is obtained glass micro mist
Effectively improve.After microcrystalline glass powder is added, the covering power of composite granule can be effectively improved calcium carbonate fine powder system.
The clear glass micropowder controlled micro crystallization adopts sintering process, and its specific technological process is as follows：Dispensing → found → water
Quench → crush → sieve → shape → sinter → reprocess, wherein sintering temperature is 700～900 DEG C.Sintering process energy glass powder
Granule bonding is produced, then powder is produced intensity and is caused densification and recrystallization through material transport, the motive force of sintering
It is the crystal boundary energy of the surface energy more than polycrystalline sintered body of granular material.
The super fine be nano-calcium carbonate, nano titanium oxide, nano silicon and Nano silica sol in extremely
Few one kind.Preferably, the super fine is at least one in nano-calcium carbonate and nano titanium oxide.
The super fine grain diameter size is 5000～8000 mesh, and Blue Whiteness value is 92～97.Add in the present invention
Plus super fine, the surface soundness of coating, overlay film or paint film can be effectively improved, super fine can effectively be filled into bulky grain
The space of filler, improves blocking water and gas barrier properties for coating etc., improves the comprehensive effectiveness of coating.
The adsorptivity between different material in blending ingredients is effectively increased as binding agent using waterglass in the present invention
Can so that the chemical stability of end-product is effectively improved.
Preferably, the composite white pigment is made up of following parts by weight ingredient：
Experiment shows that, using the composite white pigment strong covering power of above-mentioned technical proposal, whiteness is high.
Preferably, the composite white pigment is made up of following parts by weight ingredient：
