Abstract
The invention relates to glass and in particular relates to glass with antifogging and self-cleaning functions. The surface of the glass is provided with a coating which adopts sodium phosphate and sodium tripolyphosphate as dispersing agent, polyoxyethylene lauryl ether and fatty acid amine as emulsifying agent, and polyethylene glycol and dipropylene glycol as antifogging agent, so that the glass has good hydrophily and antifogging performance, antifogging time can be prolonged, an antifogging effect can be improved; moreover, a protective film is arranged on the surface of the antifogging layer for protecting the antifogging coating, so that the service life of the antifogging glass is prolonged.
Description
Technical field
The present invention relates to a kind of glass, specifically relate to a kind of antifog and glass self-cleaning function of having.
Background technology
As everyone knows, because the effect of temperature and humidity, fumulus can be coverd with in the surface of glass in season of cold, such as the glass pane in house, vehicle glass also has glasses that people wear etc., these make troubles for people's life and safety, even harm people's life security.For fear of such problem, people have carried out a large amount of research.At present, generally adopt the method for smearing one deck antifoggant on glass, but its troublesome poeration can not in time solve the problem of hazing.
Summary of the invention
In view of the problem that prior art exists, the objective of the invention is to provide a kind of and have antifog and glass self-cleaning function.
To achieve these goals, the technical solution adopted in the present invention is a kind of antifog and glass self-cleaning function of having, and it comprises: glass body, anti-fog layer, diaphragm and photocatalytic coating; Cover on the glass body and be coated with anti-fog layer, cover on the anti-fog layer and be coated with diaphragm, cover on the diaphragm and be coated with photocatalytic coating;
Described anti-fog layer is to be formed by the antifoggant spraying, and described antifoggant raw material is: sodium phosphate, sodium phosphate trimer, copolymerization of ethylene, polyethylene glycol, Isopropanediol, fatty acid amine, ethoxylated dodecyl alcohol and deionized water; The percentage by weight of each material is:
Sodium phosphate 2 ~ 4%
Sodium phosphate trimer 2 ~ 4%
Copolymerization of ethylene 1 ~ 3%
Polyethylene glycol 3 ~ 5%
Isopropanediol 0.5 ~ 2%
Fatty acid amine 3 ~ 6%
Ethoxylated dodecyl alcohol 1 ~ 2%
The surplus deionized water.
The percentage by weight of each material is preferably: sodium phosphate 3%, sodium phosphate trimer 3%, copolymerization of ethylene 2%, polyethylene glycol 4%, Isopropanediol 1%, fatty acid amine 5%, ethoxylated dodecyl alcohol 1.5% and deionized water.
The weight ratio of described sodium phosphate and sodium phosphate trimer is 1:1.
Described deionized water is the above high-frequency electric field effect of 2M that water passes through 220 volts of 50Hz power generation frequencies, and the generation physical change makes.
Described diaphragm nanometer grade silica noncrystal.
Described photocatalytic coating is the mixture of nanometer grade silica and Nano titanium dioxide, and the diameter of its silica is 5 ~ 7 nanometers, and the diameter of titanium dioxide is 6 ~ 8 nanometers.
The invention has the advantages that: be provided with at glass surface that to adopt sodium phosphate and sodium phosphate trimer be dispersant, ethoxylated dodecyl alcohol and fatty acid amine are emulsifying agent, and be equipped with the antifoggant coating of polyethylene glycol and Isopropanediol, make glass itself have good hydrophily and anti-fog function, can prolong the antifog time, improve anti-fog effect; And the anti-fog layer surface is provided with diaphragm, and it plays a protective role to antifogging coating, increases the service life of antifog glass.
