Abstract
The invention relates to automotive glass, in particular to automotive glass with anti-fog and self-cleaning functions. The automotive glass with the anti-fog and self-cleaning functions belongs to the field of glass. An anti-fog coating is arranged on the surface of the glass and has good anti-fog function, the anti-fog coating contains dispersing agents, including tea oil, polypropylene and propylene glycol, volatile perfluor oil is added into the anti-fog coating, so that the anti-fog coating has good hydrophilic property and anti-fog function; a protective film is arranged on the surface of the anti-fog coating and plays a protection effect to the anti-fog coating, and the service life of the anti-fog glass is accordingly prolonged; and a photocatalyst coating is coated on the outmost layer of the glass and can be decomposed under the radiation of ultraviolet ray, so that the hydrophilic property is strong, and the self-cleaning effect is played.
Description
Technical field
The present invention relates to a kind of vehicle glass, specifically relate to a kind of antifog and vehicle glass self-cleaning function of having, it belongs to glass art.
Background technology
Along with the development of automobile industry, vehicle flowrate is also in continuous increase on the road surface.It not only brings great pressure to traffic, brings certain injury also for people's life security.Particularly winter, the incidence of traffic accident can obviously increase.Its reason is that the road of snowing winter is sliding on the one hand, be exactly on the other hand in the car glass affected driver's sight line and hinder traffic safety by anhydrous covering.At present, generally adopt on glass covering to be coated with the antifoggant that is consisted of by surfactant and to solve this problem, but its troublesome poeration.
Summary of the invention
In view of the problem that prior art exists, the objective of the invention is a kind ofly have antifog and vehicle glass self-cleaning function.
To achieve these goals, the technical solution adopted in the present invention is a kind of antifog and vehicle 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 is: its raw material is: trifluoro propyl methyl polysiloxane, tea oil, polypropylene, propane diols, sorbitol, volatility perfluor oil, glycerine and deionized water; The percentage by weight of each material is:
Trifluoro propyl methyl polysiloxane 2 ~ 5%;
Tea oil 3 ~ 5%
Polypropylene 2 ~ 3%
Propane diols 1 ~ 3%
Sorbitol 5 ~ 6%
Volatility perfluor oil 2 ~ 5%
Glycerine 2 ~ 4%
The surplus deionized water.
Described trifluoro propyl methyl polysiloxane is for containing 50% trifluoro propyl substituting group, and relative molecular weight is 200000.
Described volatility perfluor oil is take oxygenated oil as base oil, the mixture that gets with the perfluoro solvent dilution.
Described each substance weight percentage is preferably: trifluoro propyl methyl polysiloxane 3, tea oil 4, polypropylene 3, propane diols 4, sorbitol 5, glycerine 3 and surplus deionized water.
Described diaphragm is the 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: glass surface is provided with antifogging coating, it has good anti-fog function, and it is dispersant that antifogging coating contains employing tea oil, polypropylene and propane diols, and has added volatility perfluor oil, makes it have good hydrophily and anti-fog function; 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; The outermost layer of glass covers and scribbles photocatalytic coating, and it decomposes under the ultraviolet ray irradiation, has very strong hydrophily, plays self-cleaning effect.
The specific embodiment
A kind of have antifog and vehicle glass self-cleaning function, 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 is: its raw material is: trifluoro propyl methyl polysiloxane, tea oil, polypropylene, propane diols, sorbitol, volatility perfluor oil, glycerine and deionized water; The percentage by weight of each material is:
Trifluoro propyl methyl polysiloxane 2 ~ 5%;
Tea oil 3 ~ 5%
Polypropylene 2 ~ 3%
Propane diols 1 ~ 3%
Sorbitol 5 ~ 6%
Volatility perfluor oil 2 ~ 5%
Glycerine 2 ~ 4%
The surplus deionized water.
