Description
Technical field:
The present invention relates to the glass coating field, particularly a kind of low radiation coated glass and laminated glass thereof, especially be arranged on the low-emission coated interlayer skylight glass on the vehicles.
Background technology:
Low radiation coated glass is called again low-e glass, it has the advantages such as high visible light transmissivity and high IR line reflection rate, can reduce significantly the air conditioning energy consumption of automobile and the comfort level that improves officer and passenger, therefore building and the huge market requirement is arranged above the vehicles as a kind of Green Product, the low-e glass that particularly has muted color is subject to everybody favor especially.Muted color is between between red, yellow, blue three-color, its tone is soft, sedate, proper, generous, and color is not to become clear so dazzlingly, can avoid eyestrain, give the people a kind of sensation easily, so the coated glass of muted color is aesthetic more welcomed by the people in manufacture.
Development along with technology, constantly occurred in recent years that but but tempering reached the low radiation coated glass product of hot bending, this product is mainly used in building glass field and shield glass field, however with the automobile plated film interlayer panorama skylight product of low radiation functions at home or in blank.
Panoramic sunroof of automobile is generally laminated glass, and the characteristics such as degree of safety is high, broad view that it has are the symbols of luxurious luxury car in configuration of automobiles.But most of panoramic sunroof of automobiles do not possess function of heat reflection, under sunshine, make for a long time vehicle interior temperature raise, need by air-conditioning refrigeration system in car to regulate vehicle interior temperature, can not, for the passenger inside the vehicle provides a comfortable environment by bus, can't reach again a good energy-saving consumption-reducing purpose like this.
Existing laminated glass product normally adds that by two sheet glass substrates intermediate polymer layer PVB forms, and the coated laminated glass product is to plate low-emissivity coating on the surface of one of them of two sheet glass substrates, and coated surface is towards PVB.Filming process is normally between pre-treatment and thermoforming operation, when producing coated glass, no matter be " pollution " that the front glass surface of plated film or the film surface after plated film are subject to the external world, can observe the coated glass surface and point-like macroscopic irregularity occur after the coated glass thermoforming.Particularly adopt the sandwiched product of hot bending technology, low-emissivity coating is positioned at the internal surface of glass, during hot bending, two sheet glass substrates must be stacked together and be placed on mould, two sheet glass are heated in softening process at the same time, low-emissivity coating will inevitably produce directly or indirectly and contact with the surface of adjacent glass substrate, if the cleanliness factor of adjacent glass baseplate surface is inadequate or have dust, impurity, when oil stain etc. pollute, can make film surface be destroyed so with after rete contacts, easily produce spot, the point-like of oil drop and so on or erose macroscopic irregularity.These spot defects are sometimes tiny and dim, for the sandwiched product that uses transparent PVB, are not easy to find this spot defect under available light.Yet interlayer skylight product adopts grey PVB as intermediate polymer layer usually, under the setting off of grey PVB, these spot defects become particularly evident easily to be seen, has affected so greatly the visual appearance of product, has reduced the rate that manufactures a finished product of product.
