Abstract

The invention discloses a glass structure for enhancing glass strength and a manufacturing method thereof. The glass structure is mainly composed of a glass substrate and a transparent insulating film formed on the surface of the glass substrate by coating or printing; therefore, the strength of glass is enhanced so that the glass is better in breaking resistance and shock resistance, and meanwhile, the production cost of an enterprise is not increased to a large extent.

Description

Promote glass structure of strength of glass and preparation method thereof

Technical field

The present invention relates to the glass for display device and touch-screen, relate in particular to a kind of high-intensity glass structure.

Background technology

Generally all adopt at present the soda-lime glass of 0.2mm to 2.0mm for the glass substrate of hand-set lid, display and various touch-screens.In order to make frangible glass there is the well anti-anti seismic efficiency that falls, conventionally people can carry out the chemical enhanced intensity that improves glass to common soda-lime glass, but this chemical enhanced method improves very limited to strength of glass, glass still exists frangible character, make the intensity of glass cannot meet higher strengthening requirement, do not reach perfect condition, the display of working it out and touch-screen are still easy to breakage.

Summary of the invention

To the object of the invention is the problem existing in above-mentioned technology in order solving, to have proposed a kind of glass structure that promotes strength of glass, comprise glass substrate, transparent insulating film, film plating layer.

Transparent insulating film can adopt the transparent material of OC glue, PI glue or other flexibles, adopts the methods such as coating or printing to be covered on described glass substrate.Glass substrate can adopt simple glass or tempered glass.

The invention allows for a kind of preparation method that promotes strength of glass, comprise the steps:

Step 1: by clean cleaning glass substrate and dry up;

Step 2: adopt the methods such as coating or printing, transparent insulating film is covered on glass substrate;

Step 3: the glass substrate that has covered transparent insulating film is put into baking box, toast 0.5-10 hour at the temperature of 60-300 degree Celsius, transparent insulating film is dried completely;

Step 4: be coated with the rete that plates again other needs on glass of above-mentioned transparent insulating film.

The present invention by covering the insulating materials of layer of transparent on glass substrate, as OC glue, PI glue etc., this type of organic substance has very strong toughness, can not reduce again the transparency of glass simultaneously, can effectively improve the withstand voltage and resistance to performance of falling of glass, larger raising the anti-shock resistance of falling of glass, make various display devices and touch-screen be not easy fragmentation, thereby improved its service life.Although the present invention is with low cost, effect is fairly obvious.

Brief description of the drawings

Below, the present invention is described in detail for contrast accompanying drawing and preferred embodiment, wherein:

Fig. 1 is structural representation of the present invention;

Fig. 2 is flow chart of the present invention.

Detailed description of the invention

Below in conjunction with drawings and Examples, invention is described in detail.Should be appreciated that the only technical scheme in order to explain that the present invention proposes of the explanation of specific embodiment, and non-limiting the present invention.

Fig. 1 is the structural representation of one embodiment of the invention, and the glass structure of the lifting strength of glass that the present invention proposes is to utilize the methods such as coating or printing to cover layer of transparent dielectric film on the surface of glass substrate.Transparent insulating film can adopt the organic substance such as OC glue, PI glue, and the method that covers transparent insulating film can adopt the methods such as printing or coating.By covering transparent insulating film; can improve the intensity of glass, glass is in the time carrying out falling sphere test, and the height of falling sphere can improve 2-3 doubly; this kind of glass can directly be applied in touch and the demonstration fields such as handset touch panel, particularly OGS, hand-set lid and screening glass.

Further set forth the falling ball impact test result of various embodiments of the invention below, experimental condition of the present invention is: adopt the glass of 0.7mm thickness as glass substrate, and the size of glass substrate is 150mm*100mm, glass substrate lies on acrylic flat board, the steel ball of 64g is dropped to center of glass position from freedom of the air, and the height that glass substrate can bear in chip-proof situation is height of the fall ball.Through test of many times, we have drawn following test data:

1,, when glass substrate is simple glass, height of the fall ball is 12cm;

2, glass substrate is that while being coated with other retes on simple glass, height of the fall ball is 8cm;

3, glass substrate is that while increasing transparent insulating film on simple glass, height of the fall ball is 30cm;

4, glass substrate is to increase transparent insulating film on simple glass, then while being coated with other retes, height of the fall ball is 25cm;

5,, when glass substrate is tempered glass, height of the fall ball is 20cm;

6, glass substrate is that while being coated with other retes on tempered glass, height of the fall ball is 10cm;

7, glass substrate is that while increasing transparent insulating film on tempered glass, height of the fall ball is 60cm;

8, glass substrate is to increase transparent insulating film on tempered glass, then while being coated with other retes, height of the fall ball is 50cm;

Can find out from above-mentioned test data, pass through to increase after layer of transparent dielectric film, because transparent insulating film has very strong toughness, in conjunction with the very strong rigidity of glass on the surface of glass substrate, make the frangible character of glass itself obtain good alleviation, the intensity of glass is improved greatly.

As shown in Figure 2, the invention allows for the preparation method that promotes strength of glass, its key step is:

1, select glass substrate: select well cutting, without collapsing limit breakage, without the obvious common soda lime glass substrates of cut, or glass after chemical enhanced.

2, clean glass: the glass substrate of select in previous step is cleaned up and dried up by dull and stereotyped cleaning machine.

3, cover transparent insulating film: use the methods such as printing or coating, there is the transparent insulating film of toughness at surface coverage one deck of glass substrate, this transparent insulating film can adopt OC glue or other gelatin substances, and the method that covers transparent insulating film can be utilized the methods such as printing or coating.

4, dry: the glass that has covered transparent insulating film is put into baking box, and temperature is toasted 0.5-10 hour under 60-300 degree Celsius, and transparent insulating film is dried completely.

Can be for hand-set lid glass through the glass of step 4, also can increase on this basis and be coated with the transparent conducting glass for touch-screen after other rete simultaneously.If desired make transparent conducting glass, the glass cleaning post-drying that step 4 can be formed, under 25-500 degree Celsius, the face that is coated with insulating film layer at glass by vacuum magnetic-control sputtering method is coated with nesa coating, and nesa coating can adopt the multiple rete such as ITO or SIO2+ITO or Nb2O5+SIO2+ITO.It is worth mentioning that, the invention solves the ubiquitous technical barrier because causing tempered glass intensity to decline after plated film in industry.

Above specific embodiment is only in order to illustrate structure of the present invention, and those of ordinary skill in the art can make various deformation and variation under design of the present invention, and these distortion and variation include within protection scope of the present invention.
