Abstract
The present invention belongs to the technology of glass production, and provides a coloring agent for yellow float glass with an ability of absorbing ultraviolet rays. The coloring agent comprises ingredients (measured by the percentage in the total surface weight of the glass): 0.006 to 0.18% of Fe2O3, 0.3 to 0.7% of MnO, 0 to 0.002% of Co2O3 and 0.05 to 0.25% of V2O5. The yellow float glass with an ability of absorbing ultraviolet rays produced by using the coloring agent of the present invention has the high ability of absorbing the ultraviolet rays (lower than 15%) and relatively high luminous transmittance (higher than 70%), and is suitable for the material of window glass of buildings and vehicles.
Description
Technical field
The invention belongs to glass production technology, relate generally to a kind of coloring agent for UV absorbing yellow float glass.
Background technology
Up to the present China produced tea, indigo plant, green serial antisolar glass.And having the ultraviolet yellow float glass of absorption, China's float glass industry still belongs to blank.And along with expanding economy, building, automobile and other industries will further increase the demand that absorbs ultraviolet yellow float glass.
Summary of the invention
Purpose of the present invention promptly is the tinting material that proposes a kind of UV absorbing yellow float glass.
The present invention finishes the technical scheme that its invention task taked: the essential characteristic of Na-Ca-Si sheet glass is made up of following basic ingredient: (accounting for the weight percent of glass gross weight) SiO
268-75, Na
2O 10-18 CaO 5～15 MgO 0～5 Al
2O
30～5 K
2O 0～5.(MgO Al

2O is not zero simultaneously)
The composition of parent glass is not crucial to the present invention, and this parent glass is that those skilled in that art are in common knowledge, is to produce in the continuous melting stove, and forms sheet glass by floating process.
The component and the amount ranges thereof that add tinting material of the present invention in above-mentioned parent glass component are:
Tinting material component and consumption (accounting for the per-cent of glass summary table weight)

In the toner component, iron is generally with Fe
3+And Fe
2+Form occur, in glass with Fe
3+When form occurred, it was the ultraviolet radiation absorption component, near ultraviolet range absorption band is arranged.Manganese can be used as red colour developing source to obtain yellow, if MnO
2Content is less than 0.3% (weight), it is insufficient that this kind composition promptly is tending towards, and almost can not get yellow glass, on the other hand, if it has passed through 0.7% (weight), optical transmittance promptly is tending towards lowly, and preferably when the molten glass raw material reaches the oxidation purpose, introduces SODIUMNITRATE (production process).In addition, the Co that adds 0-0.002% (weight)
2O
3As tinting material, glass colour further can be adjusted into the tone of desired yellow glass thus, it is the requirement adding according to tone.If Co
2O
3Content has passed through 0.002% (weight), and it is low that its optical transmittance promptly is tending towards.Add V

5Can increase glass to ultraviolet specific absorption.
In above-mentioned scope, preferable content is as follows: (accounting for the per-cent of glass summary table weight)
Fe
2O
3：0.07-0.18
MnO
2： 0.3～0.68
Co

5：?0.06～0.23
Utilize the UV absorbing yellow float glass of tinting material production provided by the invention to have high ultraviolet absorption ability (less than 15%) and relative high optical transmittance (greater than 70%), be applicable to the glazing material of buildings and vehicle.
In the present invention, the tinting material that adds in glass is formed is the form with oxide compound, but does not get rid of other form.As the one skilled in the art in other form of knowing except that oxide compound, as element form, also can be used in the batching composition, but in batching fusion and treating process, it will transform into the oxide form of the disclosed scope of the present invention, be similarly feature of the present invention and contain.
