Abstract
The invention discloses composite titanium dioxide which is characterized by being prepared from the following components in parts by weight: 20-40 parts of titanium dioxide, 60-80 parts of calcined kaolin and 1-3 parts of a silane coupling agent. The composite titanium dioxide is prepared by the steps: grinding the calcined kaolin; mixing the calcined kaolin with titanium dioxide and silane coupling agent and pulping the mixture to prepare a 20-25% solution; and washing and drying the solution and carrying out treatment by strong magnetization on the solution to obtain a finished product. The composite titanium dioxide disclosed by the invention is simple in production process and low in energy consumption. In the wet milling process, a hyperdispersant is added to prevent powder from being agglomerated to affect whiteness covering power of the final product to lead to a poor performance of the product.
Description
Technical field
The present invention relates to a kind of preparation method of titanium dioxide, particularly relate to a kind of composite titanium dioxide.
Background technology
Titanium dioxide take crystalline titania as main component, crystalline titania makes titanium dioxide have the strongest covering power far above the specific refractory power of other inorganics thus becomes best white pigment, but the resource consumption of titanium dioxide is too much, cost is excessive, many producers are had to adopt titanium dioxide substitute and titanium dioxide to be prepared into composite titanium dioxide at present, in order to ensure composite granule, here titanium dioxide substitute refers to the performance with titanium dioxide and cost is lower than titanium dioxide, partly or entirely can substitute the inorganic powder material that titanium dioxide is employed, because pursuit low cost and the large one's duty of efficiency are all adopt dry process on current upper market, but although dry process is simple, but covered effect is undesirable, whiteness is not high enough, opacifying power is inadequate, adopt wet ball grinding technique may occur anti-crushing phenomenon, cause powder reuniting phenomenon, finally cause whiteness not high enough, opacifying power is inadequate.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of composite titanium dioxide, and described composite titanium dioxide adopts wet ball grinding technique to obtain, and there will not be powder reuniting phenomenon, has the performances such as whiteness is higher, strong covering power.
In order to solve the problem, technical scheme of the present invention is a kind of composite titanium dioxide, and described composite titanium dioxide is made up of following parts by weight ingredient: 20 ~ 40 parts of titanium dioxides, 60 ~ 80 parts of calcined kaolins, 1 ~ 3 part of silane coupling agent.
A preparation method for composite titanium dioxide, its preparation process is as follows:
1) ground by calcined kaolin, mixed with titanium dioxide, silane coupling agent by the powder after grinding, make solution, the concentration of solution is 20 ~ 25%;
2) to step 1) in mixed solution carry out wet ball grinding art breading, and add hyper-dispersant in mechanical milling process, the amount of hyper-dispersant is step 1) in solute 1%;
3) mixed solution after wet ball grinding technique is washed, drying step process, and obtain composite titanium dioxide work in-process;
4) screening in strong magnetic sieve is sent into the composite titanium dioxide work in-process after drying treatment, obtain composite titanium dioxide finished product.
Further, the calcining temperature of described calcined kaolin is 750 ~ 950 DEG C.
Further, described step 2) in hyper-dispersant be polyester type ultra-dispersant agent.
Further, described step 3) in washing step by solution washing to neutral solution.
Further, described step 3) in time of wet ball grinding technique be 3 ~ 4h, ball milling speed is 140r/min.
Beneficial effect of the present invention: production technique is simple, and energy consumption is low, adds hyper-dispersant in wet ball grinding process, prevents powder from occurring agglomeration, affects whiteness and the opacifying power of last product, causes the poor performance of product.
Accompanying drawing explanation
Fig. 1 is present invention process schema.
