Description
Technical field
The invention belongs to the technical fields of compounded mix, provide a kind of microspheroidal composite titanium dioxide and system for coating
Preparation Method.
Background technique
Titanium dioxide has that refractive index is high, reducing power is strong, covering power is big, good dispersion, whiteness are good, nontoxic, physics and chemistry
Property is stablized, and has excellent optics, electric property.Therefore its purposes it is very extensive, coating, plastics, papermaking, chemical fibre,
Ink, rubber, cosmetics etc. will use pigment-level titanium dioxide.It is coating that wherein dosage is maximum, accounts for about 57%.It is especially golden
Red stone-type titanium dioxide, it is most of to be consumed by coatings industry.It is rapid with Chinese Automobile Industry ', building industry and water paint
It emerges, coatings industry not only needs more titanium dioxides in quantity, but also, kind higher to quality requirement requires more.
Titanium dioxide due to the more other white pigments of production cost are much higher and titanium ore resource it is increasingly in short supply so that its
Using being restricted.How titanium white production cost is reduced into the project of current urgent need research.The pigment performance of titanium white particle
It is embodied by optical property, optical property depends primarily on TiO2The surface nature of particle, therefore, TiO2Optics is checked in particle
Performance is almost without contribution.If a kind of white material cheap and easy to get can be used to replace kernel, titanium white unit cost will be big
It is big to reduce.Composite titanium dioxide is exactly based on using cheap nonmetallic mineral as kernel, coats one layer of TiO on its surface2Particle
And it is made.
Current each state is all studying and is exploring composite titanium dioxide (or substitute of titanium dioxide), to reduce its cost.Closely
The composite titanium dioxide with mica, kaolin, talcum, wollastonite, calcium carbonate etc. for core, being respectively used to successively are developed over year
The industries such as cosmetic, coating and papermaking meet middle and low-end market demand.Currently, the research and development of China's composite titanium dioxide also in
Primary stage, properties of product are bad, can only generally replace the 10 ~ 30% of titanium dioxide.Therefore the application of titanium dioxide can not still neglect
Depending on, and it is the most important research contents in practical application in organic media dispersibility.
It has been obtained in terms of titanium dioxide technology of preparing, especially polymolecularity, inexpensive composite titanium dioxide both at home and abroad at present
Certain effect.Wherein Li Jiangong et al. has invented a kind of composite titanium dioxide and its preparation process (Chinese invention patent application number
201210144449.6), by each component according to following weight: 40 ~ 60 parts of inorganic particle, 40 ~ 60 parts of titanium dioxide, stearic
0.2 ~ 0.5 part of acid esters, 0.2 ~ 0.5 part of containing hydrogen silicone oil, it is activated, feed, form a series of technique be made, used in the invention
The amount of titanium dioxide is very low, and using the hydrophilic stearate of oleophylic and containing hydrogen silicone oil is modified and coated inorganic powder, Ji Nengyong
In solvent based coating, and titanium dioxide can be replaced in water paint and emulsion paint.In addition, that a kind of titanium cladding is illustrated is light for Xu Chun long hair
The preparation method (Chinese invention patent application number 201610291993.1) of the composite titanium dioxide of matter calcium carbonate, including following step
It is rapid: butyl titanate a, being dissolved in into formation butyl titanate solution in organic solvent；B, lightweight carbonic acid is added into butyl titanate solution
Calcium, it is evenly dispersed at suspension；C, under stirring, deionized water is at the uniform velocity added into suspension, makes butyl titanate
Hydrolysis is aged 10 ~ 20min later；D, it is passed through nitrogen into suspension, under nitrogen protection, methyl methacrylate is added, stirs
Mix 5 ~ 10min；E, after system being heated to 70 ~ 80 DEG C, a small amount of initiator is added, carries out 40 ~ 60min of surface treatment；F, surface
System Temperature fall filters slurries with Buchner funnel, and clean filter cake with deionized water, dries, powder by after treatment
It is broken；The preparation method for the composite titanium dioxide that the invention provides improves the pigment performance of titanium dioxide product, enhances it in organic solvent
In dispersion stabilization and its weatherability.
As it can be seen that untreated titanium dioxide main component in the prior art is titanium dioxide, surface is by polar group institute
Attachment, therefore titanium dioxide is easy to generate agglomeration because of polarity absorption or the moisture absorption, is difficult to disperse in organic media, and mesh
The method effect of preceding modification is undesirable, higher cost, therefore it is wide in the composite materials such as coating to affect titanium dioxide
General application.
