Description

Technical Field

[0001] The present invention relates to the technical field of glass manufacturing, and specifically to a fireproof insulating glass and its manufacturing process. Background Art

[0002] Currently, the fireproof insulating glass generally consists of two or more layers of fireproof glass. The periphery of the fireproof insulating glass is bonded and sealed with a high-strength and high-airtightness composite adhesive to bond and seal two or more pieces of glass with a sealing strip and a glass strip; dry gas is filled in the middle, and a desiccant is filled in the frame to ensure the dryness of the air between the glass sheets;

[0003] The advantage of this kind of fireproof insulating glass is that the assembly is simple. For example, a spacer frame and a side seal are installed between two pieces of glass to achieve the connection and sealing effect between the two pieces of glass; however, the disadvantages are also obvious. For example, when the side seal is scratched and damaged later, it is easy to lose the airtightness of the fireproof insulating glass; in addition, when inert gas needs to be re-introduced after the airtightness of the insulating glass is lost later, the sealing strip needs to be completely removed, and then inert gas is introduced between the two pieces of glass again, and then the sealing strip is used for sealing again;

First, it can improve the sound insulation effect of the entire fireproof insulating glass, and second, it enhances the fireproof performance of the fireproof insulating glass;

[0034] At position A, between the inner side of the outer glass 1 and the inner side of the inner glass 3, sealed installation and fixation are achieved through a sealing rubber head 5 and a spacer frame 8. The spacer frame 8 is located on one side of the sealing rubber head 5. Among them, both sides of the sealing rubber head 5 are installed and fixed between the outer glass 1 and the inner glass 3 through sealing edge strips 6. Card slot grooves 13 are respectively opened on both sides of the spacer frame 8, and sealing card strips 9 are installed and fixed at the positions where the card slot grooves 13 are opened on both sides of the spacer frame 8. The provided sealing card strips 9 seal and install and fix the spacer frame 8 between the inner side of the outer glass 1 and the inner side of the inner glass 3. Desiccant particles 10 are filled inside the spacer frame 8, and a filter screen 11 is installed at a position on one side of the spacer frame 8 facing the inert gas layer 4.

One end of the pressure relief valve 7 is inserted into the positioning hole 12 opened in the middle of the spacer frame 8.

[0035] At position B, between the inner side of the outer glass 1 and the inner side of the inner glass 3, sealed installation and fixation are achieved through a sealing rubber head 5 and a spacer frame 8. Both sides of the sealing rubber head 5 are simultaneously sealed and installed with the inner wall of the outer glass 1 and the inner wall of the inner glass 3 through sealing edge strips 6. Card slot grooves 13 are opened on both sides of the spacer frame 8, and at the positions where the card slot grooves 13 are opened on both sides of the spacer frame 8, sealed installation is achieved between the inner side of the outer glass 1 and the inner side of the inner glass 3 through sealing card strips 9. At the same time, desiccant particles 10 are filled inside the spacer frame 8, and a filter screen 11 is opened at a position on one side of the spacer frame 8 facing the inert gas layer 4.

[0036] In the embodiment of the present invention, the silicon fireproof film 2 that is simultaneously pasted on the inner wall of the outer glass 1 and the inner wall of the inner glass 3 improves the fire resistance performance of the entire fireproof insulating glass. And inert gas is introduced into the inert gas layer 4 formed between the inner side of the outer glass 1 and the inner side of the inner glass 3. The inert gas introduced inside the inert gas layer 4 improves the sound insulation effect and fire resistance performance of the entire fireproof insulating glass.

[0037] The spacer frame 8 provided between the inner side of the outer glass 1 and the inner side of the inner glass 3 constitutes the framework for connecting the outer glass 1 and the inner glass 3 of the fireproof insulating glass. The desiccant particles 10 filled inside the spacer frame 8 can be used for moisture absorption operation inside the inert gas layer 4 to maintain the dryness degree inside the inert gas layer 4. And the sealing rubber head 5 located on one side of the spacer frame 8 improves the sealing performance of the connection and installation between the outer glass 1 and the inner glass 3. The pressure relief valve 7 installed inside the sealing rubber head 5 can be used for later replacement of the inert gas inside the inert gas layer 4, and the provided pressure relief valve 7 has a one-way valve function.

[0040] Please refer to Figure 4 , in an embodiment of the present invention, a movable cavity 20 is provided at the middle position inside the pressure relief valve 7, a movable valve 18 is movably installed inside the movable cavity 20, the movable valve 18 is in a T shape, the movable valve 18 is fixedly installed on the movable rod 16, and a rubber edge 19 is also filled on the movable valve 18; at the same time, front and rear partitions are respectively provided at the front and rear ends of the movable cavity 20 inside the pressure relief valve 7, a left air hole 17 is provided on the front partition, and a right air hole 24 is provided on the rear partition; the front and rear ends of the movable rod 16 located inside the movable cavity 20 are respectively slidably installed on the front partition and the rear partition, and at the same time, a baffle 22 is also provided on the part of the movable rod 16 located inside the movable cavity 20, and a compression spring 21 is sleeved on the part of the movable rod 16 between the movable valve 18 and the baffle 22;

[0042] After the inert gas enters the opening cavity 15, it first enters the movable cavity 20 through the left air hole 17 provided on the front partition, pushing the movable valve 18 movably installed inside the movable cavity 20 to slide and displace, so that gaps are formed between the upper and lower positions of the movable valve 18 and the upper and lower cavity walls of the movable cavity 20 for passing the inert gas, and then it continues to enter the exhaust hole 23 through the right air hole 24 provided on the rear partition, and finally the inert gas is guided into the inert gas layer 4 through the exhaust hole 23 and temporarily stored;

[0043] When the inert gas temporarily stored inside the inert gas layer 4 is filled up, the air supply pump stops supplying air. At this time, under the action of the elastic variable generated by the deformation of the compression spring 21 sleeved on the movable rod 16 and the reverse pressure generated by the inert gas injected into the inert gas layer 4, the provided movable valve 18 automatically returns to its initial state, and the rubber baffle 19 provided inside the movable valve 18 tightly closes the gap position, thereby finally making the inert gas filled inside the inert gas layer 4 in a sealed state;
