Description

Safety laminated glass

Technical Field

The utility model belongs to the technical field of glass, and particularly relates to safety laminated glass.

Background

The film material that current doubling glass adopted is PVB, and PVB is the most widely used sandwich glass intermediate material of tradition, and the sandwich glass who adopts PVB to make can absorb the ultraviolet ray completely, has good syllable-dividing and falls the advantage of making an uproar, but its tear strength and hardness are all lower, and rigidity and reliability are also not good enough. Based on the reasons, the safety laminated glass provided by the utility model has the advantages of good strength, rigidity and reliability, simple structure and higher economy.

Disclosure of Invention

The purpose of the utility model is as follows: in order to overcome the defects in the prior art, the utility model provides the safety laminated glass which has the advantages of good strength, rigidity and reliability, simple structure and higher economy.

The technical scheme is as follows: in order to achieve the purpose, the safety laminated glass comprises laminated glass, wherein the laminated glass is formed by sandwiching a film between two pieces of glass, and the film of the film is dissolved with air;

the periphery of the laminated glass is provided with a circle of edge covering layers along the contour of the laminated glass, and the edge covering layers completely cover the side edges of the films and partially cover the side edges of the glass so as to seal the seams between the glass and the films.

Furthermore, micropores are densely distributed on two surfaces of the film, which are attached to the glass.

Further, the film is made of SGP materials.

Furthermore, the periphery of the laminated glass is provided with a groove extending along the central line for a circle, the inner side of the edge coating layer is coated with structural adhesive, and the edge coating layer is laid in the groove and is adhered to the laminated glass through the structural adhesive.

Further, the outer side of the edge covering layer is flush with the outer peripheral side of the laminated glass.

Furthermore, the inner side of the edge covering layer is a frosted structure surface, and the structure adhesive is smeared on the frosted structure surface.

Further, the structural adhesive is cured to form a hard adhesion frame structure.

Furthermore, the edge covering layer is of an edge covering pad structure made of PVC materials.

Has the advantages that: the safety laminated glass has the beneficial effects that:

1) the glass has better rigidity and reliability, can effectively reduce the use thickness of the glass, and is a better choice for the separation design of the oversized glass;

2) the moisture absorption is lower, so that the water is effectively prevented from being soaked, and the bubble degumming is avoided;

3) has better transparency.

FIG. 1 is a schematic diagram of the overall structure of the present invention;

FIG. 2 is an exploded view of the present invention;

FIG. 3 is a schematic diagram of the present invention in a half-section and with a part of the structure enlarged.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, fig. 2 and fig. 3, a safety laminated glass includes a laminated glass 1, the laminated glass 1 is formed by sandwiching a film 3 between two pieces of glass 2, air is dissolved in a film of the film 3, more specifically, the film 3 is formed by an SGP material, and has the advantages that:

4) the tearing strength of the SGP is 5 times that of PVB, the hardness is 100 times, the thermoplastic temperature of the SGP material is 20 ℃ higher than that of the PVB, the rigidity and the reliability are better, the use thickness of glass can be effectively reduced, and the SGP material is a better choice for the separation design of ultra-large glass;

5) the moisture absorption is lower, so that the water is effectively prevented from being soaked, and the bubble degumming is avoided;

6) the SGP has good cohesiveness reaching 20.7MPa and better transparency.

The manufacturing method of the laminated glass comprises the following steps: the film 1 is clamped between two pieces of glass 2, after prepressing, the air in the middle is exhausted as much as possible, and then the residual small amount of air is dissolved into the adhesive film by utilizing high temperature and high pressure to form the glass.

The periphery of doubling glass 1 has been laid round layer of borduring 4 along its contour laminating, the side of layer of borduring 4 covers film 3 completely and partially covers glass 2's side to it is sealed with the seam between glass 2 and the film 3, and is more specific, layer of borduring 4 is the pad structure of borduring that comprises the PVC material. Has the advantages that: the peripheral sides of the laminated glass 1 are sealed and covered, so that gaps between the glass and the rubber sheets are covered, the glass and the rubber sheets are subjected to water and gas permeation prevention, structural damage protection is also performed, and degumming is avoided.

More specifically, micropores 30 are densely distributed on two surfaces of the film 3, which are attached to the glass 2, so that a small amount of residual air can be conveniently and rapidly dissolved into the adhesive film, and the processing efficiency is improved.

It is worth noting that the periphery of the laminated glass 1 is provided with a groove 10 extending along the central line for one circle, the inner side of the edge covering layer 4 is coated with a structural adhesive, the edge covering layer 4 is laid in the groove 10 and is adhered to the laminated glass 1 through the structural adhesive, the structural adhesive is cured to form a hard adhesion frame structure 5, and the outer side of the edge covering layer 4 is flush with the peripheral side of the laminated glass 1. The tightness of the arrangement of the edge covering layer 4 is ensured.

The inboard of bordure layer 4 is dull polish structural plane 40, the structural glue is paintd on dull polish structural plane 40, improves the adhesion steadiness.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the utility model and these are intended to be within the scope of the utility model.
