Description
Technical field
The invention belongs to titanium white production technical field more particularly to a kind of calcium base titanium dioxide and its preparation processes.
Background technology
Titanium dioxide is the white mineral matter filler pigment that main component is titanium dioxide (TiO2), is provided simultaneously with high covering
The weatherability of power, high reducing power, best bright finish, high whiteness and stabilization, while also there is chemical inertness, nontoxic, harmless
Etc. performances, thus as the best white pigment of performance so far, be widely used in plastics, rubber, papermaking, coating, ink,
The industries such as paint.Especially coating industry is the maximum user of titanium dioxide, and the coating made of titanium dioxide is bright in luster, covers energy
Power is high, and strong coloring force is low-consuming, wide in variety, can play a protective role to the stability of medium, and the machinery that can enhance paint film is strong
Degree and adhesive force, prevent crackle, prevent ultraviolet light and moisture from penetrating, extend the paint film service life.At the same time, due to the life of titanium dioxide
Produce that the more other white pigments of cost are high, and titanium ore resource in recent years is increasingly in short supply so that the extensive use of titanium dioxide by
Certain restrictions, more it is worth noting that in China, since most titanium dioxides all use the more serious sulfuric acid of environmental pollution
Method is produced, so the substitute of research and exploration titanium dioxide is to have important practical significance to solve the above problems.
Traditional titanium dioxide substitute refers to having the performance of titanium dioxide and cost is lower than titanium dioxide, being capable of part or complete
Portion substitutes the inorganic powder material that titanium dioxide is applied.From the 70's of 20th century, titanium dioxide substitute has just started to grind
Study carefully and develop, and achieves certain economic benefit.If composite titanium dioxide is used for synthetic fibers by Japan, Britain and Germany will systems
At talcum composite titanium dioxide have been used for papermaking, mica, kaolin are prepared composite titanium dioxide product by the U.S. with TiO2 respectively,
Partial is applied to cosmetic industry.Meanwhile the preparation of most composite titanium dioxides, all there is agglomeration, product is shown
Covering power is low, weatherability is insufficient, and reducing power shows the problems such as unsatisfactory equal, and thus current titanium dioxide technology is one
Determine to be to sacrifice the due performance of part titanium dioxide in degree and the substitution titanium dioxide that carries out, substitution titanium white completely can't be reached
Powder.
Invention content
A kind of whiteness is high, oil factor is big the purpose of the present invention is in view of the above shortcomings of the prior art, providing, covering power
Strong calcium base titanium dioxide, can be used as filler material and is widely used in the industries such as papermaking, paint, coating, rubber, daily use chemicals, building materials, ink
In product.
Meanwhile it is a further object of the present invention to provide a kind of preparation processes of above-mentioned calcium base titanium dioxide.
Technical solution used by the purpose of the present invention is：Calcium base titanium dioxide, including by the ultra tiny carbon of 4000-6000 purposes

2-3 parts of coating agent presses 1 with soft water together：The ratio of 2-3 is uniformly mixed in No. 3 pre- storage tanks；
2）By step 1）In in three pre- storage tanks while be added in the hybrid reaction tank of stirring at low speed, mixing speed control
At 5-10 revs/min, reacts 1-2 hours, make particle surface hydroxylating；
3）By step 2）Acquired solution is sent into thtee-stage shiplock paddle-type mill, and using PLC control system, control reaction high speed is ground
Machine, with 4500-6600 revs/min of rotating speed, grinds 2 ± 0.2 hours at a temperature of 55-68 DEG C, obtains calcium base titanium lotion；
4）By step 3）Gained calcium base titanium lotion is sent into thermal current and cures drying chamber, carries out rapid curing drying, forms calcium
The prefabricated material of base titanium dioxide；
5）By step 4）The prefabricated material of gained calcium base titanium dioxide is sent into modified abrasive machine, and 3-5 parts of modifying agent is added, and carries out
Modified abrasive repairs 3-5 hours to get finished product calcium base titanium dioxide.
The dispersant is polycarboxylate sodium.
The coating agent is Lauryl Alcohol ester.
The modifying agent is polyether modified silicon oil.
The present invention is by the way that super fine calcium carbonate, titanium dioxide and dispersant to be uniformly mixed with three parts respectively with coating agent
Aqueous solution form is temporarily stored into three pre- storage tanks, to effectively prevent above-mentioned raw materials to same holding vessel be added in the case of, hold
The phenomenon that easily reuniting, make super fine calcium carbonate that dispersity, dispersant, coating agent effectively be kept to make particle as medium
Effectively complete hydroxylating is realized on surface, and particle is made to have good dispersion performance and stability.In addition, through PLC control system
The mechano-chemical reation that paddle-type mill time, speed, temperature and the charge of thtee-stage shiplock generate is controlled, using dynamics and heat
Mechanics principle carries out inorganic coating, so that outer membrane is evenly coated, is fine and close, being firmly combined with.It is homogenized by dry solidification, powder grinding,
Modified, reparation coating, keeps coating more mellow and fuller, to effectively improve whiteness, oil factor and the covering power of product.Using this work
Calcium base titanium dioxide made from process, after testing：Whiteness reaches 97%-99%, oil factor 29-35g/100 g, covering power>35.4g/
㎡, product index reach or are more than national standard.
Applicant lasts the composite calcium-base titanium dioxide for developing the application in 5 years, is widely used as papermaking, paint, coating, rubber
Filler material in the industries product such as glue, daily use chemicals, building materials, ink improves the product quality of relevant industries, increases product added value
Deng being environmentally protective, high-tech, high value added product, imported material can be substituted completely, ton price is only the three of imported material
/ mono-, production cost is greatly reduced for the production of user enterprise, pilot product firmly gets favorable comment after on probation, and product promotion is answered
It is very big with space.Product applications have been expanded, industry chain (supply chain) has been elongated, have been played for the fast development of China's titanium dioxide industry
Positive impetus.
