Embodiment Construction
[0026] Below in conjunction with embodiment the present invention is described in further detail.
[0027] specific method:
[0028] (1) For normal assembling, the bottom of the first 18A aluminum frame 1 is first coated with butyl glue on the upper surface of the first flat glass 2;
[0029] (2) Then spread the 4mm thick aluminum mesh plate 3 on the upper surface of the first flat glass 2 and be located in the first 18A aluminum frame 1, leaving a 2--3MM expansion gap around;
[0030] (3) Use the 14A aluminum strip to automatically bend it to the required size (subject to the fact that the inner edge of the first aluminum frame is not loose, and the maximum gap between the two aluminum frames is 0.5MM), forming the second 14A aluminum frame 4;
[0031] (4) Use low-volatility, high-viscosity 0.01MM thick VHB double-sided tape, cut into 100MM sections with an interval of 200MM, and evenly paste them on the outer frame of the 14A aluminum frame 4, and then press the second 14A ...

The invention relates to a method for fixing an aluminum screen board in insulating glass. The method comprises the following steps: 1) a first aluminum frame is fixed to the upper surface of first plain glass; 2) the aluminum screen board is placed in a surrounding range of the first aluminum frame, wherein gaps are reserved between the peripheral edges of the aluminum screen board and the firstaluminum frame; 3) a second aluminum frame is produced, wherein the height of the second aluminum frame is equal to the difference between the height of the first aluminum frame and the thickness of the aluminum screen board, and VHB (very high bond) double sided adhesive tapes are bonded to the outer side of the second aluminum frame at intervals; 4) the bottom of the second aluminum frame is pressed on the periphery of the aluminum screen board and stuffed in the first aluminum frame, and an outer side frame of the second aluminum frame and an inner side frame of the first aluminum frame arefixed through VHB double sided adhesive tapes; and 5) the tops of the first aluminum frame and the second aluminum frame are coated with adhesives and fixed to the lower surface of second plane glass. The aluminum screen board is relatively fixed in an inner cavity of the insulating glass by friction and cannot move and shake randomly, the aluminum screen board has a larger expansion space for free expansion and contraction, and an expansion bending phenomenon of the aluminum screen board can be avoided.
Description
technical field [0001] The invention relates to a method for processing glass products, in particular to a method for fixing aluminum mesh plates in insulating glass. Background technique [0002] The insulating glass has excellent thermal insulation performance due to the air in the middle. At the same time, the insulating glass is laminated or fixed with an aluminum mesh plate, which can reflect light, further improve the sunshade effect, and also have a certain beautification effect. [0003] The Chinese patent "a hollow glass with aluminum mesh" (ZL2017218752971) proposes a structural glass in which an aluminum mesh is added to the insulating glass. Since the aluminum mesh is easy to expand with heat and contract with cold, the thermal expansion coefficient of the aluminum mesh and the glass is It is not the same, so the temperature of the aluminum mesh panel rises under the hot sun in summer, and the aluminum mesh panel is easy to expand and bend; however, the aluminum ...
