3D glass；
Step 4, will be hot-forming after glass carry out acid etching processing, produce the 3D glass of anti-dazzle.
The acid etching carries out carrying out acid etching to the 3D glass after hot bending using fluorine-containing solution, and acid etching depth is preferably high
In 5 μm.The acid etching processing not only acts as the effect gently changed to 3D glass surface micro-structurals, corrects AG specifications, enters simultaneously
The effect of row surface passivation reinforcing glass intensity.When implementing, only the micro-structural face of 3D glass can be entered according to actual needs
Row acid etching, can also carry out acid etching to the two-sided of 3D glass.The present invention handles fluorine-containing solution used not to acid etching
Do specific restriction, commercially available fluorine-containing solution.
Improved as a kind of the of preparation method of the anti-dazzle 3D glass of the present invention, the roughness of the coarse structure is
0.02~2μm。
To be improved as a kind of the of preparation method of the anti-dazzle 3D glass of the present invention, the hot-forming temperature is 500 ~
900℃。
Improved as a kind of the of preparation method of the anti-dazzle 3D glass of the present invention, the hot bending clamp material be graphite or
Ceramics.
Improved as a kind of the of preparation method of the anti-dazzle 3D glass of the present invention, it is described hot-forming under protective atmosphere
Carry out.
Improved as a kind of the of preparation method of the anti-dazzle 3D glass of the present invention, the protective gas is nitrogen or argon
Gas.
A kind of anti-dazzle 3D glass, it is made by any above-mentioned preparation method.
The present invention has the advantages that：This merges the making of anti-dazzle and 3D glass in a process, Neng Goubao
The uniformity of bending area and the anti-dazzle light effect in other regions is demonstrate,proved, cost of manufacture is greatly reduced, simplifies technological process, carry
High product yield；The 3D glass of local anti-dazzle or overall anti-dazzle light effect can be produced according to actual needs, meet different
User's request, further expands its application and improves competitiveness.3D glass surfaces after hot-forming have micro-structural,
But micro-structural corner angle are obvious, be excessively sharp, it is impossible to realize anti-dazzle light effect, and surface has micro-crack generation to have a strong impact on glass
Intensity, and the present invention is entered the 3D glass with micro-structural using the hot-forming synergy both with acid etching of micro-structural
The processing of one step etching, makes its tending towards stability of microstructure area, while being modified AG specifications, also glass surface is passivated
Play a part of reinforcing glass intensity.
