Abstract
The present invention relates to the exploitation of nonmetalliferous ore wollastonite, use, a kind of titanium dioxide that utilizes wollastonite to be compounded to form particularly is provided.It is mainly by TiO
2, CaSiO
3, ZnO, Al
2O
3And silane coupling agent constitutes.The key technical indexes of composite titanium dioxide and performance are all near the rutile-type R of import like this
820Titanium dioxide, this product all have tangible characteristics alone at aspects such as weathering resistance and rub resistances.
Description
The invention belongs to exploitation, the application of nonmetalliferous ore wollastonite, particularly a kind of wollastonite compound titanium dioxide that utilizes.
In the field that produces products such as rubber, plastics, pottery, need to use a large amount of titanium dioxides as filler.At present, the titanium dioxide market supply and demand of home and abroad is very nervous, China is annual to want a large amount of import titanium dioxides, has caused the problem that needs a large amount of foreign exchanges to pay in this.
The objective of the invention is, adopt wollastonite modified to make major ingredient, a kind of composite titanium dioxide is provided.
The wollastonite reserve of China is very big, and the major ingredient of its wollastonite is calcium metasilicate (CaSiO
3) it has ore body pure white (whiteness reaches 98 °), iron-holder is low, and the needle prosperity has the advantages that weather resistance reaches weathering resistance and rub resistance by force.
Calcium metasilicate can carry out the compound composite titanium dioxide that obtains with titanium dioxide after modification.Composite titanium dioxide provided by the invention is formed by following substances and proportioning:
TiO
2：25～35%
CaSiO
3：60～75%
ZnO ：2～7%
AI
2O
3：1～3%
Silane coupling agent: 0.5～1.5%
The present invention provides a new approach again for the purposes of wollastonite, and its performance of the composite titanium dioxide that obtains and the key technical indexes are near the rutile-type R from external introduction
B20Titanium dioxide makes it to greatly reduce use cost, and this product all has tangible characteristics alone at aspects such as weathering resistance and rub resistances.
If adopt TiO
2-30%, CaSiO
3-62%, ZnO-6%, AI
2O
3-1%, silane coupling agent-1% carries out compoundly, will obtain a kind of good composite titanium dioxide.
Claims (2)
1, a kind of composite titanium dioxide is characterized in that, it is by following substances
TiO
2： 25～35%
CaSiO
3： 60～75%
ZnO： 2～7%
Al
2O
3： 1～3%
Silane coupling agent: 0.5～1.5%
Constitute.
2, by the described a kind of composite titanium dioxide of claim 1, it is characterized in that each concrete ratio that constitutes thing is: TiO
2: CaSiO 30%,
3: ZnO 62%: AI 6%,
2O
3: silane coupling agent 1%: 1%.
