[0053] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to facilitate a thorough understanding of the present invention and to fully convey the concept of the present invention to those skilled in the art.

[0054] See also Figures 1 to 3 As shown, an embodiment of the present invention provides a vacuum glass support and a preparation method thereof, comprising a vacuum glass 100, wherein the insulating glass 10 comprises at least two groups of insulating glass 10 and laminated glass 40 of equal size and arranged parallel to each other, and at least one group of supporting members 20 arranged between the insulating glass 10 and the laminated glass 40, wherein the supporting members 20 comprise at least one group of first supporting members 201,

[0055] The support member 20 also includes at least one group of second support members 205, and the first support member 201 and the second support member 205 are both provided with a glass glaze layer 204, and are sintered and installed on the insulating glass and the laminated glass 40 respectively through the glass glaze layer 204, so that the support member 20 is tightly connected to the insulating glass and the laminated glass 40. The support member 20 can be hemispherical, cylindrical, square, polygonal, etc., preferably hemispherical.

[0056] In this embodiment, the support member 20 is sintered and installed on the insulating glass or laminated glass 40, so that the support member 20 is tightly connected to the insulating glass or laminated glass 40, thereby greatly reducing the probability of the support being displaced or falling off during the movement of the vacuum glass, thereby improving the performance and reliability of the vacuum glass.

[0057] See also Figures 1 to 3 As shown, the support is provided by two groups of insulating glass 10 and laminated glass 40 which are of equal size and arranged in parallel with each other, and a vacuum layer 50 is separated between the two groups of glass. An exhaust channel 60 is provided in the vacuum layer 50, and the vacuum layer 50 is evacuated into a vacuum through the exhaust channel 60.

[0058] Furthermore, a suction piece 70 is provided on one side of the exhaust channel 60, and the suction piece 70 uses a long-lasting getter; by placing the suction piece 70, the vacuum degree of the vacuum glass is improved and maintained, thereby extending the service life of the vacuum glass.

[0059] In this embodiment, when the two groups of glass (hollow glass and laminated glass) that make up the vacuum glass are subjected to pressure, the two parallel and corresponding glass will move inward, causing the vacuum layer to gradually shrink or even disappear, turning the vacuum glass into ordinary double-layer glass, thereby greatly reducing its performance. In order to ensure the existence of the vacuum layer, metal supports are usually placed between the two pieces of glass for spacing and support. However, the sound insulation performance of vacuum glass with a size of 50cm*50cm using metal supports is poor. In order to improve the sound insulation performance, some manufacturers use elastic supports, but when the elastic supports are subjected to pressure, the elastic supports will undergo a certain elastic deformation, which will cause gas and bubbles to appear in the vacuum layer, thereby affecting the overall performance of the vacuum glass. To solve the above problems, please refer to Figures 1 to 3As shown, the outer wall of the support member 20 is coated with glass glaze, and the height of the support member 20 is 0.2-11mm, and the width of the support member 20 is 0.2-6mm; the height of the support member 20 is preferably 0.15mm, and the width of the support member is preferably 0.3mm; the spacing between the two groups of support members is preferably 30mm; the support member 20 includes a first support member 201 and a second support member 205; the first support member 201 and the second support member 205 are both provided with a glass glaze layer 204, and the glass glaze layer is provided so that the first support member and the second support member have a certain hardness and are convenient for sintering and installation on two pieces of glass;

[0060] The first support member 201 is provided with a first elastic wrapping layer 202 , and the second support member 205 is provided with a second elastic wrapping layer 206 . Both the first elastic wrapping layer 202 and the second elastic wrapping layer 206 are provided with at least one group of channels filled with air.

[0061] Furthermore, a first pressure body 207 is installed in the glass glaze layer 204 disposed on the first support member 201 , and the first pressure body 207 abuts against the bottom end surface of the first elastic wrapping layer 202 .

[0062] Furthermore, a second pressure body 203 is installed in the glass glaze layer 204 disposed on the second support member 205, and the second pressure body 203 abuts against the bottom end surface of the second elastic wrapping layer 206, and the first elastic wrapping layer and the second elastic wrapping layer are made of porous elastic material.

[0063] Furthermore, the first pressure body 207 and the second pressure body 203 are respectively arranged based on the diagonal line of the support member and are arranged opposite to each other, so that they are respectively arranged at two ends of the diagonal line of the support member.

[0064] In this embodiment, when the support is subjected to a certain overload pressure, the two pieces of glass arranged in parallel and correspondingly move inward, and the two sets of pressure bodies are pressed downward, and the elastic wrapping layer is squeezed by the pressure bodies. At the same time, the gas in the channel of the elastic wrapping layer is squeezed out of the channel. When the air in the channel rushes out of the channel, an impulse force FB is generated;

[0065] At the same time, since the elastic wrapping layer itself has many tiny gaps inside, when the elastic wrapping layer is deformed by external force, the gaps in the elastic wrapping layer are subjected to pressure FA, causing them to gradually shrink; and the air in the channel is instantly squeezed out by pressure, generating an impact force FB that is greater than the pressure FA. Under the action of the impact force FB, the air enters the pores of the elastic wrapping layer, playing a certain supporting role and preventing the gaps in the elastic wrapping layer from being compressed; and when the pressure disappears, the elastic wrapping layer uses its own elasticity to rebound. At this time, the gaps in the elastic wrapping layer are filled with air, forming a certain rebound support, thereby greatly reducing the impact force generated during rebound, making the overall elastic deformation smaller; the sound insulation of the vacuum glass supported by the elastic support reaches 40dB, thereby improving the sound insulation performance while greatly improving the overall performance of the vacuum glass.

[0066] Furthermore, the vacuum glass is made by the following steps:

[0067] (1) Pretreatment to obtain insulating glass and laminated glass;

[0068] (2) A plurality of supporting members are arranged between the insulating glass and the laminated glass, and the glass glaze layer of the supporting members is sintered and installed on the insulating glass by high temperature processing technology;

[0069] (3) Laying the sheets together: placing another laminated glass 40 on the support member that has been set, and aligning it with the insulating glass with multiple support members, and using high-temperature processing technology to sinter the glass glaze layer at the other end of the support member that is set diagonally and install it on the laminated glass 40, so that the support member 20 is tightly connected to the insulating glass and the laminated glass 40;

[0070] (4) Welding the outer edges of the formed insulating glass and laminated glass together with a glass solder layer (low melting point electrodeless glass sealing material) to form a gap (vacuum layer) between the two sets of glass;

[0071] (5) 70-90% of the air in the gap is extracted and the edges are sealed to make it a vacuum state (P≤0.1PA);

[0072] (6) Detection.

[0073] Further, the support member 20 is manufactured by the following steps:

[0074] (1) Wrapping the outer side of the pressure body (the first pressure body and the second pressure body) with a glass glaze layer, so that the inner wall of the glass glaze layer is in contact with the outer wall of the pressure body, and the contacting position is filled with solder;

[0075] (2) Soaking the obtained support member 20 in potassium hydroxide for 9-12 minutes;

[0076] (3) High temperature processing technology is used to melt the solder at the location where the inner wall of the glass glaze layer and the outer wall of the pressure body are bonded, and the glass glaze layer is firmly welded to the outer wall of the pressure body.

[0077] See also Figures 1 to 3 As shown, the insulating glass 10 includes at least two groups of insulating glass 10 and laminated glass 40 of equal size and arranged parallel to each other, and at least one group of supporting members 20 arranged between the insulating glass 10 and the laminated glass 40 .

[0078] Furthermore, the insulating glass uses at least two pieces of glass with a thickness of h, and uses a high-strength and high-airtightness composite adhesive to bond the glass pieces to the sealed drying member 103 to form a highly efficient sound-insulating and heat-insulating insulating glass; h is preferably 3, 4, 5, 6, 8, 10, 12 mm thick original glass; and the distance between the two pieces of glass is 12 mm.

[0079] In this embodiment, the dryness of the insulating glass is kept unchanged by embedding a sealing drying member in the insulating glass.

[0080] Furthermore, the laminated glass 40 is made of at least two pieces of glass, and a film 401 is arranged between the two pieces of glass. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process treatment, the glass and the film are permanently bonded into one laminated glass 40. The film 401 is preferably PVB, 5GP, EVA, or PU film.

[0081] In this embodiment, the present application document makes vacuum glass by replacing the existing original glass with hollow glass and laminated glass, thereby greatly improving the sound insulation performance and service life.

[0082] Sound insulation performance test:

[0083] Sound is generated by the vibration of an object and propagates in the form of sound waves. Sound propagation requires a medium. The propagation effect can be simply divided into solid>liquid>gas from good to bad. The more rigid and dense the material is, the better the propagation effect. Similarly, when sound propagates to one of the sheets of vacuum glass, it needs to be transmitted to the other sheet through a support. The weaker the rigidity of the support, the better the barrier effect. The support of the present invention includes a first support and a second support, and the first support 201 is provided with a first elastic wrapping layer 202, and the second support 205 is provided with a second elastic wrapping layer 206, and at least one set of channels are provided in the first elastic wrapping layer 202 and the second elastic wrapping layer 206, and the channels are filled with air. The weaker the rigidity of the support, the stronger the sound insulation. At the same time, since the elastic wrapping layer itself has many tiny gaps inside, this undoubtedly enhances the sound insulation performance.

[0084] The present invention uses glass fiber support, metal support and ceramic support. Figure 4As shown, the vacuum glass provided with the support has good sound insulation performance of the vacuum layer, and is superior to the ceramic support or the metal support, especially in the medium and low frequencies to which the human ear is sensitive.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
