Abstract

The safe sandwiched glass consists of two outer layers of glass and one layer of sandwiched ethylene-vinyl acetate copolymer (EVA) with high resolution figure produced through intaglio printing or silk screen printing on one side. It is produced by the processes of intaglio printing or silk screen printing to form high resolution figure on EVA film, vacuum treatment of the EVA film, and heating adhesion the EVA film between two layers of glass.

Description

A kind of decorating laminated glass of two-sided perspective and manufacture method

The present invention relates to the manufacturing field of laminated safety glass, mainly propose a kind of decorating laminated glass and manufacture method of two-sided perspective.

Existing safety interlayer glass is generally water white or monochromatic coloured glass such as dark brown, light grey, yellow etc. and makes, though this safety glass has transparency and shockproof properties preferably, and has obtained using widely in building industry.But it is single, ornamental relatively poor and can't satisfy the weak point of social development to exist purposes.

The laminated glass that also has many employing silk-screened glasses to make in recent years, image sharpness is lower, to draw film thicker and make between the double glazing gummed tight and have only deficiency such as single face decorative effect but exist.Recently occur a kind of employing polyvinyl acetate-ethylene copolymer (EVA) again and be the decorating laminated glass of film, it is owing to be the structure that adopts double-layer film therebetween one deck decorative layer, thereby it has decorative effect, broad-spectrum advantage preferably, sees through deficiencies such as effect is relatively poor but exist complex structure, light.

The object of the present invention is to provide a kind ofly to have good safety anti-vibration performance, and the decorating laminated glass of the two-sided perspective that light penetration is higher, radiation-resistant property is good and manufacture method.Its pattern is owing to adopted advanced intaglio printing or screen printing technique, and picture is printed on above the eva film, thereby picture is thin and clear, the double glazing bonding is tight, simple in structure, and has the effect of two-sided perspective.

Purpose of the present invention is achieved through the following technical solutions: it is made of up and down layer glass and middle polyvinyl acetate-ethylene copolymer (EVA) film, has on the face of eva film to adopt intaglio printing or screen printing technique to handle and the high-resolution image that obtains;

Its manufacture method is: adopt intaglio printing or screen printing technique to form the picture of fine definition on polyvinyl acetate-ethylene copolymer (EVA) film, treated eva film is placed between two sheet glass, close sheet, under vacuum condition, add heat bonding after closing sheet, form the two-sided perspective decorating laminated glass.

The two-sided perspective laminated glass that adopts said method to produce, the advantage that has not only kept existing laminated safety glass safety anti-vibration in good condition, and owing to adopted advanced intaglio printing or screen printing technique, its image sharpness height, it is thin and bright-coloured transparent to draw layer, the colour image positive and negative visual effect unanimity of product, has good two-sided perspective function, this product adopts novel eva film simultaneously, thereby have also that production procedure is simple, the easy advantage of reasonable of technological operation, be that a kind of decorate properties is preferable, purposes is decorated laminated safety glass more widely.

Embodiment:

The accompanying drawing 1 that provides is embodiment of the invention structural representation.

Among the figure, 1 is skin glass, and 2 is eva film, and 3 is bottom glass.

It constitutes: by layer glass 1 up and down and 3 and middle polyvinyl acetate-Ethylene copolymer (EVA) film 2 consists of, and has employing on the face of eva film Intaglio printing or screen printing technique are processed and the high-resolution image of acquisition;

The manufacture method of two-sided perspective decorating laminated glass of the present invention, principal character is simultaneously to carry out intaglio printing or serigraphy through pretreated EVA film, the film of this process printing treatment placed between two sheet glass close sheet, under vacuum condition, add heat bonding after closing sheet, promptly make the two-sided perspective decorating laminated glass that possesses three-decker.

Accompanying drawing 2 provides process chart.

Embodiment:

1, get glass ready material on request after, carry out clearly with conventional glass cleaner Wash and dry;

2, cleaning, drying is carried out in eva film requirement routinely, adopt the technology of intaglio printing or serigraphy then, the pattern that the printshop designs on eva film;

3, the eva film that prints is cut on request the area of prescribed level;

4, the eva film that this was handled places between two sheet glass and closes sheet;

5, in vacuum chamber, carry out operation (prior art);

6, adding heat bonding in the condition that vacuumizes gets final product.

Claims

1, a kind of decorating laminated glass of two-sided perspective, it is characterized in that: constitute by up and down layer glass (1) (3) and middle polyvinyl acetate-ethylene copolymer (EVA) film, have on the face of eva film and adopt intaglio printing or screen printing technique to handle and the high-resolution image of acquisition;
