Description
Technical field
The utility model relates to a kind of automobile laminated glass that has the multifunctional film-coating coating, is specifically related to building, the compound coated glass of automotive field, relates in particular to the compound coated glass of automotive field.
Background technology
The light pollution problem that is caused by luminous reflectance more and more attracts much attention, the luminous reflectance of building curtain wall has become the main light pollution source in city, because the visible reflectance of the internal surface of shield glass is bigger, therefore with the front windshield internal surface as minute surface, just make automobile instrument panel as minute surface specular reflection take place with the front windshield internal surface, will upset officer's vision like this, thereby traffic safety is brought hidden danger.How reducing the specular reflection of front windshield internal surface, is the problem that those skilled in the art need solve.
Infrared rays belongs to invisible heat, and the infrared rays in the summer sunlight can see through in the glass inlet chamber or in the car, and its internal temperature is raise; Winter, room temp was higher, and heat can be by glass flows to outdoor, and the two all can make the refrigeration of air-conditioning or heating electric energy increase.So, under the theme background of building energy conservation environmental protection at present, how to reduce the refrigeration expense of summer air-conditioning and the consumption that how to reduce the warming electric energy, all be the problem that need solve.
Because atmospheric pollution exists bacterium, dust, organic pollutant etc. in the atmosphere, in a single day these pollutents just are not easy to remove attached to glass surface now, and the glass curtain wall cleaning of particularly present high buildings and large mansions is a difficulty and dangerous bigger work especially; Also there are similar problem in vehicle glass, particularly front windshield.How feed glass surface, particularly glass outer surface, cleaning, also be to be badly in need of a technical work solving.
Find by retrieval, there has been prior art to address the above problem respectively at present, specifically comprised: solved the specular reflection problem of front windshield internal surface separately, solve increase problem, and the problem that is difficult to clean of glass outer surface of summer air-conditioning refrigeration expense and warming power consumption separately.
Internal surface at front windshield plates antireflecting coating, can solve the specular reflection problem of front windshield internal surface; Plate low-emissivity coating on the windshield glass surface, also be Low-E coating, can solve the problem that summer air-conditioning refrigeration expense and warming power consumption increase; Outside surface at front windshield plates automatic cleaning coating, can solve the problem that glass surface is difficult to clean, and the pollutant removal of glass surface is fallen in the effect that automatic cleaning coating can be by sunlight or rainwater.
Chinese patent 200410012951.7 discloses titanium nitride base low-radiation self-cleaning coated glass and preparation, adopts magnetron sputtering method production, plates transition layer, dielectric layer, TiN successively at glass surface
x, metal level and titanium dioxide layer; TiN wherein
xEffect with reflected infrared; And titanium dioxide layer has self-cleaning function, by photochemical catalysis can glass surface and water between wettability better, pollutent is eliminated under rainwash.
