Description

A kind of SGP doubling glass

Technical field

This utility model belongs to laminated glass technical field, is specifically related to a kind of SGP doubling glass and preparation method thereof.

Background technology

Laminated glass is by two panels or divided glass, between pressed from both sides one or more layers organic polymer intermediate coat, after special high temperature precompressed and high-temperature high-pressure craft process, make the compound glass product that glass and intermediate coat permanent adhesive are integrated. Conventional laminated glass intermediate coat has PVB, SGP, EVA, PU etc. Even if the glass fragmentation in laminated glass, fragment also can be bonded on thin film, and broken glass surface still keeps neatly smooth. This is not only to avoided injury accident, also as laminated glass has fabulous antidetonation invasive ability, intermediate coat can resist the continuous attack of the lethal weapon such as hammer, firewood cutter, moreover it is possible to resisting bullet within the long duration penetrates, and its safety precaution degree is high.

Wherein, SGP film is laminated glass ionomer intermediate coat, its excellent performance, and tearing strength is 5 times of general PVB film, and hardness is 30-l00 times of PVB film. During low deformation rate, SGP laminated glass shows as bullet plastic properties and PVB is superlastic plasticity, and during high strain rate, PVB is hardening and becomes bullet plastic properties, and SGP rigidity in gamut is higher. The monolithic glass of SGP laminated glass and same thickness is how many equal bending strength. Comparing with other intermediate coat laminated glass, SGP laminated glass has higher strength character and rigidity, can efficiently reduce thickness of glass, is especially beneficial for point type support glass. SGP laminated glass has a extensive future at design of glass lighting roof and glass exterior window, curtain wall, well. SGP doubling glass is as safety glass very reliably, particularly it is widely used in some important explosion-proof places at building field, SGP doubling glass is to be produced by certain production technology by more than 2 glass and SGP film, owing to the material of SGP film is harder, film can only produce the sheet material of certain specification, the demand of various doubling glass cannot be met, this is accomplished by splicing according to glass size size, and ensures not dock vestige at joint and do not have the defects such as bubble.In existing SGP doubling glass production technology, when film size cannot meet order needs, required film is carried out cutting according to glass-board surface size, and use electric cautery to be stitched together by SGP film, production and processing is carried out according still further to the doubling glass mode of production, this production technology is discontinuous production, and production efficiency is very low. SGP film needs the substantial amounts of time to splice, and the trace spliced as seen in stitching portion is with easily at the many minute bubbles of stitching portion generation, and the experiment of boiling of product is also unable to reach the requirement of the world. Cause that the reason of disadvantages mentioned above is owing to glass-board surface is relatively big, 2 or all of stitching portion of multi-disc SGP film are all welded together spent time with electric cautery longer; After subsequent production machines, it is clear that the vestige seeing splicing; If splicing operation processes bad, it is easy to produce minute bubbles in stitching portion thus causing waste product.

Utility model content

In order to solve the problems referred to above, the purpose of this utility model is in that the SGP doubling glass providing a kind of stitching portion not dock the defect such as vestige and bubble.

This utility model is achieved through the following technical solutions:

A kind of SGP doubling glass, including at least two blocks of glass and the SGP glue-line that is folded between two blocks of glass, described SGP glue-line is spliced by least two pieces of SGP substrates, and described two pieces of SGP substrate stitching portions are also folded with a SGP adhesive tape identical with described SGP substrate material. SGP substrate can not be fused together, the place in gap inherently starved, and only one SGP of patch supplements and could be filled a vacancy in the place of splicing.

It is preferred that the length of described SGP adhesive tape is identical with the width of described SGP substrate.

It is preferred that the thickness of described SGP adhesive tape is 0.89mm.

It is preferred that the width of described SGP adhesive tape is 6��10mm.

It is preferred that the thickness of described two pieces of SGP substrates is 1.52��3.04mm. The size of SGP adhesive tape is comparatively crucial, need not too much without very little, finally still having obvious joint seam trace too much, affect attractive in appearance; Fill out discontented gap very little, bubble can be produced, it is desirable to the capacity that just can fill up seam is just much of that.

The preparation method of described SGP doubling glass, particularly as follows:

A. the SGP substrate of certain specification is selected according to glass length and specification;

B. cut the SGP adhesive tape of corresponding size according to SGP substrate, first piece is laid SGP substrate;

C. a described SGP adhesive tape is overlapped on the top of each SGP substrate seam crossing; SGP glue is overlapped on the top of two pieces of SGP substrate seam crossings.

D. after all of seam crossing has all overlapped SGP adhesive tape, then undertaken closing sheet by the second sheet glass and first;

If multilamellar doubling glass, this repeatable above-mentioned steps.

E. the glass after conjunction sheet is put into and vacuum bag carries out evacuation process;

F. finally carry out pressing process, prepare described SGP doubling glass.

It is preferred that in described step E, vacuum is more than-0.6MP��-1.0MP. Evacuation, can eject by seam crossing air, it is to avoid form steam bubble.

It is preferred that in described step F, pressing pressure 12��14MP, temperature 135��145 DEG C.

This utility model includes upper and lower two blocks of glass and the SGP glue-line being folded between two blocks of glass, and described SGP glue-line is spliced by least two pieces of SGP substrates, and described two pieces of SGP substrate stitching portions are also folded with a SGP adhesive tape identical with described SGP substrate material; And prepared by evacuation and high-temperature laminating.Mainly by film, in autoclave, film is when high pressure and high temperature for it, and film has the feature of mobility, and a film of overlap joint is melted at high temperature and pressure and is filled up in the space of the seam crossing of film, thus reaching product requirement. The final SGP doubling glass stitching portion prepared is made not have the film docking defect such as vestige and bubble. The method not only increases production efficiency and product quality, makes the production process of SGP doubling glass achieve continuous production simultaneously; And the cooperating of subsequent production technique, make product quality reach Standard.
