Abstract
The invention discloses a method for processing glass with anti-fouling self-cleaning performance and harmful compound decomposing performance. The method comprises glass pretreatment, surface acidification, baking, preparation of a chemical reagent, coating, standing and heating for curing. The chemical reagent is coated on the surface of the glass, the main component of the chemical reagent is a nano-scale titanium dioxide photocatalyst, and the titanium dioxide photocatalyst can directly enter bacterial shells under the action of ultraviolet, kill bacteria and play a role in sterilizing; and the titanium dioxide photocatalyst has good hydrophilic property and self-cleaning performance, and can automatically clear the residual dirt on the surface and play a self-cleaning role.
Description
Technical field
The present invention relates to the glass processing field, relate to a kind of working method concretely with anti-fouling and self-cleaning performance and the glass that decomposes hazardous compound.
Background technology
Improving constantly of Along with people's standard of living, in continuous raising, indoor environment also becomes the focus that people pay close attention to people to the requirement of living environment.At present, the glass that generally uses can only play effects such as insulation and printing opacity, and it can not play germ-resistant effect; Simultaneously the outside surface of glass directly directly contacts with rainwater, koniology, and the easy residual spot of glass surface influences the cleanliness factor of glass; Need the labor cleaning, the waste of manpower resource.Now, along with increasing gradually of Highrise buildings, the difficulty of labor cleaning's glass is also in gradually increase, and people be prone to accidents, thereby a kind of glass with self-cleaning effect are imperative in the high-rise glass of cleaning.
Summary of the invention
In view of the defective that prior art exists, the present invention will provide the working method with anti-fouling and self-cleaning performance and the glass that decomposes hazardous compound.
Be to realize that above-mentioned purpose, the present invention have the working method of anti-fouling and self-cleaning performance and the glass that decomposes hazardous compound, it comprises that glass pre-treatment, surperficial acidifying, baking, chemical reagent prepare, spray, leave standstill and heating cure.
Said glass pre-treatment can adopt material such as washing composition to remove the spot of glass surfaces, as: oil stain, rust stain etc. clean up with clear water afterwards again.
Said surface acid turns to the hydrochloric acid of 0.01-0.1% or sulfuric acid cleaned glass surface, cleans up with clear water afterwards.
Said baking be glass with dryer under 75-85 ℃ temperature, dried 20-30 minute.
Said chemical reagent preparation, its composition is divided into: Nano titanium dioxide photocatalyst, nano level silicon oxide, alumina in Nano level, ethanol, silicon sol and water, its weight percent is:
Nano titanium dioxide photocatalyst: 3%-10%;
Nano level silicon oxide: 2%-5%;
Alumina in Nano level: 1%-4%;
Ethanol: 0.5%-1.0%;
Silicon sol: 0.5%-1.0%;
All the other are water.
The chemical reagent for preparing is sprayed with spray gun, and spray gun adopts the pressure of pressurized gas to need greater than 0.5MPa, and on feed channel, freezing type drier and water-and-oil separator is installed, in order to remove moisture and the oil in the pressurized air.
Said leaving standstill placed sprayed glass 24-48 hour in air naturally, and heating cure is put middle oven dry with glass at 300-500 ℃, oven dry 3-5h.
The present invention compares with currently available products, has following outstanding advantage and positively effect:
1, scribble chemical reagent on the surface of glass, its staple is the Nano titanium dioxide photocatalyst, and it is under action of ultraviolet ray, and it is inner directly to get into the bacterium shell, and killing bacteria plays germ-resistant effect.
2, photocatalyst of titanium dioxide has wetting ability and self-cleaning preferably, can remove the residual spot on its surface automatically, plays self-cleaning effect.
3, in chemical reagent, contain silicon sol, be chemical reagent firm attached to glass surface, the work-ing life of the self-cleaning effect of glass.
