Problems solved by technology

However, the organic glue used in the general interlayer film is prone to deterioration and failure under the action of long-term sunlight, high temperature in summer and low temperature in winter, which will lead to a decrease in the strength of the glass. Due to the failure of the organic glue, these glass fragments have nowhere to attach and fly around, so it is easy to cause accidents of injury
Not only that, the anti-theft and sun-proof effects of this laminated glass are not ideal enough
In addition, the fire resistance performance is not ideal

Embodiment 1

[0026] Such as figure 1 The structure shown is Embodiment 1 of the present invention, and it comprises inner and outer two layers of glass 1, 2 and interlayer film, and two layers of transparent interlayer films are sandwiched between inner and outer two layers of glass, wherein one layer of interlayer film is protective Film 3 is used to improve the performance of the laminated glass in an all-round way. The protective film is made of American Masterbao brand protective film. The performance of the laminated glass is superior, which can greatly improve the ability of the laminated glass to withstand the impact of external forces, and can even resist the shooting of a pistol, as if the glass is equipped with a layer of invisible armor, which can effectively prevent accidents and patronage from thieves, and also make the laminated glass have a Excellent fire prevention, heat insulation, heat preservation and anti-ultraviolet function; another layer of intermediate film is trans...

Embodiment 2

[0035] Such as figure 2 The structure shown is the second embodiment of the present invention, which is different from the first embodiment in that: there is also a light-adjusting layer 5 that can control the transparency of the glass between the interlayer films between the inner and outer layers of glass 1 and 2, The dimming layer is composed of a liquid crystal mixed with a dimming film and phosphor powder, it is located between the transparent film and the protective film, and two power cord ends 51, 52 that can form a loop are connected to the edge of the dimming layer . When the power is turned on, the light-adjusting layer 5 can become blurred within 1 second under the action of the voltage, making the laminated glass produce a frosted effect, thereby changing the perspective of the glass. After the power is cut off, the light-adjusting layer 5 returns to the transparent state. In addition, a layer of PVC transparent film 6 is added between the protective film 3 and...

Embodiment 3

[0046] The difference between this embodiment and the second embodiment is that the transparent film is PVB film, and its composition is polyvinyl butyral. Compared with PVC film, its impact resistance and UV protection effect are better.

[0047] The manufacture method of the laminated glass of the present embodiment is:

[0048] a. Clean the surface of the fireproof tempered glass with water or alcohol, and then air dry;

[0049] b. In the clean room, spread a layer of transparent PVB film on one side of the glass;

[0050] c. Spread a light-adjusting layer on the transparent PVC film;

[0051] d. Lay a layer of protective film on the dimming layer;

[0052] e. Spread a layer of PVB transparent film on the protective film;

[0053] f. Add a layer of fireproof tempered glass cleaned with water or alcohol on the PVB transparent film in step e;

[0054] g. Put the material that has completed the above steps into the lamination furnace and pressurize it, and continue heating...

Abstract

The invention discloses a laminated glass including an inner layer glass, an outer layer glass and a intermediate film, characterized in that, at least one of the inner layer glass and the outer layer glass is safety, fireproof and toughened glass, at least two layers of transparent intermediate films are arranged between the two layers of glass, wherein one layer is a protective pad pasting. The invention also discloses the process for making the laminated glass.

Description

technical field [0001] The present invention relates to a kind of glass, especially to a kind of laminated glass, and the present invention also relates to the manufacturing method of this kind of laminated glass. Background technique [0002] Laminated glass used in buildings is usually required to have functions such as impact resistance, earthquake resistance, fire prevention, sun protection, and sound insulation. The laminated glass in the prior art is generally formed by bonding two or more pieces of glass with a transparent interlayer film under heating and pressure conditions, so that the strength of the glass is increased and the ability to resist ultraviolet rays is improved. When the glass is broken due to external impact, due to the action of the interlayer film, the fragments will also be stuck by the film, so that the whole piece of glass remains integral, avoiding injury to people or property due to flying fragments. However, the organic glue used in the gener...
