Abstract
The invention discloses a clarifying agent used for TFT-LCD substrate glass and a preparation method thereof. The clarifying agent comprises, by weight, 0.5-5% of a valence-variable oxide, 92-99.5% of an oxygen supply and 0-5% of a chloride salt. According to the invention, the clarifying agent prepared from the valence-variable oxide, the oxygen supply and the chloride salt has good clarifying effects. The clarifying agent is free from arsenic and antimony, and therefore the clarifying agent is advantaged by being environment friendly. The clarifying agent prepared by the invention has better clarifying effects than a clarifying agent having a single component. The clarifying property is improved largely. The clarifying agent prepared by the invention can be used for manufacture of substrate glass. The preparation method is simple, and is low in cost.
Description
Technical field
The invention belongs to TFT ?LCD base plate glass preparation field, be specifically related to a kind of TFT ?the LCD base plate glass with finings and preparation method thereof.
Background technology
Due to the particular requirement of liquid crystal panel manufacturing process, existing market main flow base plate glass product all belongs to the silicate glass containing boron and aluminium without alkali system.Because this glass viscosity value is high, be unfavorable for the clarification of bubble, the object that effective finings is each company's primary study always so seek.(before 2006) in early days, arsenic oxide arsenoxide (As2O3) be widely used in TFT ?the material side of LCD base plate glass, yet along with environmental requirement is more and more stricter, the oxide compound of this severe toxicity is progressively banned use of.Each company once made great efforts to carry out substitute for arsenic (As) clarification with antimony (Sb) clarification, yet same existence of antimony (Sb) causes the problem of environment and healthy aspect, and compares with arsenic, and the validity of antimony (Sb) cycle finings reduces.So, be necessary to provide a kind of Clarification Performance good, and eco-friendly finings.
Summary of the invention
The object of the present invention is to provide a kind of TFT ?the LCD base plate glass with finings and preparation method thereof, its clarifying effect is good, and environmental friendliness.
For achieving the above object, the present invention adopts following technical scheme to realize:
A kind of TFT ?LCD base plate glass finings, by mass percentage, comprise 0.5～5% the oxide compound that appraises at the current rate, 92～99.5% oxygen donator and 0～5% villaumite.
The described oxide compound that appraises at the current rate is one or both in stannic oxide, cerium oxide, lanthanum trioxide.
Described oxygen donator is the inorganic salt oxygen donator.
Described inorganic salt oxygen donator is one or both in nitrate, vitriol.
Described nitrate is one or both in strontium nitrate, nitrate of baryta, magnesium nitrate, nitrocalcite, zinc nitrate.
Described vitriol is one or both in Strontium Sulphate, calcium sulfate, barium sulfate, Tai-Ace S 150, sal epsom, zinc sulfate.
Described villaumite is a kind of in calcium chloride, bariumchloride, aluminum chloride, magnesium chloride, zinc chloride.
A kind of TFT ?the LCD base plate glass by the preparation method of finings, will appraise at the current rate oxide compound, oxygen donator and villaumite are put into mixing tank, mix, obtain TFT ?LCD base plate glass finings.
With respect to prior art, the beneficial effect that the present invention has: the present invention adopt TFT prepared by appraise at the current rate oxide compound, oxygen donator and villaumite ?LCD base plate glass finings, has Clarification Performance good, owing to not containing arsenic and antimony, so have eco-friendly advantage, obviously better than one-component finings clarifying effect, greatly improve the glass clarifying performance, can be applied to better in the manufacture of base plate glass.Preparation method of the present invention is simple, and cost is low.
