Technical field
That the present invention relates to is the preparation method of self-cleaning glass, especially a kind of preparation method of sol-gel method self-cleaning glass.
Background technology
Nano-TiO
2Super hydrophilic and photochemical catalysis effect discover by Tokyo Univ Japan the earliest.Ultimate principle is: under solar light irradiation, and nano-TiO
2After absorbing near-ultraviolet light, light induced electron and hole make nano-TiO respectively
2The hydrogen reduction of surface adsorption and water oxidation generate O
-2With-the OH active gene, these active genes are enough to make organic dirt, microorganism and the bacterial degradation on surface to become CO
2And H
2Simple inorganics such as O.Meanwhile, also find nano-TiO under study for action
2Film is after rayed, and the surface has Superhydrophilic and photocatalytic activity, if the blocking light source, these characteristics still can keep for some time in the dark.
Based on above principle, various countries are launching a large amount of work aspect fundamental research and the applied research, the research that especially outstanding is in the self-cleaning glass field.Relevant technology includes magnetron sputtering, chemical gaseous phase deposition, electrostatic spraying, cathode electrodeposition, sol-gel method or the like.Because each research institution is different with the method that manufacturer adopts, and makes the finished product performance difference very big.The problem that exists mainly contains: outward appearance rainbow problem, the low problem of glass transmitance, film adhesion difference problem, expensive problem etc.
