Abstract
The invention discloses granular titanium dioxide and a preparation method thereof. The granular titanium dioxide is characterized by consisting of the following components in percentage by weight: 80-90% of titanium dioxide, 8-12% of superfine macromolecular microcrystalline wax and 5-15% of silane coupling agent. In the invention, the powder titanium dioxide is made into granules; without a resin carrier, the titanium dioxide and surface treatment auxiliaries are perfectly compatible with various resin materials, and the use is not limited by the resin variety; the granular titanium dioxide is directly mixed with the resin without adding other auxiliaries, and the shortcoming that the titanium dioxide is difficult to disperse in resin is remarkably improved in early treatment; moreover, due to the high titanium content, the granular titanium dioxide is very suitable for producing backlight materials; at present, domestic production of a backlight material is always performed after granulation while the granular titanium dioxide can be directly mixed with the resin at a super-high amount for direct production, so that the granulation process is reduced, and the cost is saved; and finally, the dust generation is avoided in the trial use of the granular titanium dioxide, thereby reducing the environmental pollution.
Description
Technical field
The invention belongs to a kind of granule titanium white and preparation method thereof。
Background technology
Titanium dioxide is pulverous material of a kind of white, and due to the restriction of its mode of production, powder titanium dioxide produces substantial amounts of dust in plastic cement industry use procedure, and labor operation environment is produced serious pollution。And will produce dispersion when addition reaches more than 1% uneven even due to situation that powder body cannot produce too much for powder titanium dioxide in producing in reality plasthetics。
In recent years market there is people powder titanium dioxide and resin material are carried out co-extrusion pelletize as carrier, user is played a role in plastic cement produces, but due to plastic resin different types of plastic resin molecular structure difference various in style, to cause that co-extrusion product out in use receives the content of greatly constraint and this co-extrusion pelletize product titanium dioxide out non-normally low, thus by cost and easy to use on select limited。
In this context, I takes charge of the granule titanium white of research and development is by adding the auxiliary agent the carrying out peplos separating treatment again by the pretreatment just powder body titanium dioxide of some row of auxiliary on the basis of powder titanium dioxide, powder titanium dioxide is caused not reunite, it is shaped pelletize granular titanium dioxide out because of high without resin carrier and concentration, it is possible to stop the powder body pollution to environment for any plastic resin greatly facilitates user in the mode through physical impact molding。
Summary of the invention
The technical problem to be solved is to provide a kind of granule titanium white and preparation method thereof。
This invention address that the technical scheme that above-mentioned technical problem is taked is as follows:
A kind of granule titanium white and preparation method thereof, it is characterised in that granule titanium white is made up of 80wt.% ~ 90wt.% titanium dioxide, the ultra-fine polymer crystallite wax of 8wt.% ~ 12wt.% and 5wt.% ~ 15wt.% silane coupler by mass percentage；
Its preparation process is:
Step one: by mass percentage ultra-fine for 8wt.% ~ 12wt.% polymer crystallite wax and 5wt.% ~ 15wt.% silane coupler will be loaded ball milling ball pretreatment；
Step 2: liquid slurry auxiliary agent and 80wt.% ~ 90wt.% titanium dioxide after ball milling pretreatment being mixed put into high speed dispersor and carries out high speed dispersion, make liquid flux permeate uniformly and carry out surface treatment among titanium dioxide；
Step 3: titanium dioxide after surface treatment is put into three-wheel grinder and carries out pre-dispersed process；
Step 4: the principle that the titanium dioxide input granulator after grinding pre-dispersed process is freezed off by hot melt is carried out granulating and forming。
Preferably, in the step one of described granule titanium white and preparation method thereof, the rotational speed of ball-mill of ball milling ball pretreatment is 200 ~ 300 revs/min。
Further, it is preferable to, in the step one of described granule titanium white and preparation method thereof, the process time of ball milling ball pretreatment is 1-2 hour。
Further, it is preferable to, the step 2 high speed dispersing speed of described granule titanium white and preparation method thereof is 1200 revs/min。
Further, it is preferable to, the step 2 high speed jitter time of described granule titanium white and preparation method thereof is 5-10 minute。
After this invention takes such scheme, by means of powder titanium dioxide is made granular because of the auxiliary agent without resin carrier, titanium dioxide and surface treatment all can good and various resin material compatible, on using, kind by resin is not limited；Its two granules titanium white directly with mixed with resin without adding other auxiliary agents again, the process of this product early stage improves titanium dioxide not easily scattered shortcoming in resin greatly；Its three granules titanium white is high because of its titaniferous amount, is especially suitable for production backlight source material, and current domestic production backlight source material usually first carries out pelletize and then producing, and this product can directly be directly produced with the mixing of resin superelevation amount, reduces granulating working procedure, saves cost；Its four this product graininess will not produce dust on probation, reduces environmental pollution。
