Technical field
The present invention relates to glass processing technical field, particularly relate to a kind of preparation method of energy-conservation heat mirror film double glazing.
Background technology
Along with the high speed development of building curtain wall, the form of building curtain wall is more and more paid attention to energy-conservation effect, and therefore the performance of building curtain wall to glass and the parameter request of each side are more and more higher.For building glass, daylighting, view, decoration are the basic demands to glass, and energy-saving and environmental protection are the further requirements to glass, and are more and more subject to social attention.Existing market product has 1, three glass two chamber double glazings are that three sheet glass combine, and its conventional glass composition structure is: glass A+ interval box+glass B+ interval box+glass C, and its feature comprises:
(1) glass can select LOW-E glass, laminated glass, toughened glass etc. different classes of according to different demands;
(2) interval box can be selected the unlike material such as aluminum strip, warm edge strip, desiccant-filled in interval box, and the thickness of interval box is not typically chosen in 6mm-30mm not etc.
(3) between interval box and glass, adopt double sealing glue to seal (first seal gum, second seal gum), first seal gum is generally butyl rubber, and second seal gum can be poly-sulphur glue, silicone adhesive etc.
(4) superiority of double glazing is embodied in: because the thermal conductivity of air is very low, dry air that cannot convection current is sealed between glass, can effectively delay heat and scatter and disappear by the mode of conduction, thereby reach energy-conservation, antisweat texts.
But the double glazing in this common three glass two chambeies, the problem of bringing also can not be ignored:
(1) weight of glass increases, and causes the pressure of door-window section bar, five metals to strengthen;
(2) increase the trim of spacer bar, caused the ratio that double glazing lost efficacy to increase.
Glass in the middle of (3) two pressure that cavity is different cause bears large stress, easily causes glass rupture.
