Embodiment 1

[0013] Provide a kind of preparation method with double-layer glass with decoration, comprising steps are:

[0014] (1) Mix polyvinyl butyral and a plasticizer, and extrude to obtain a PVB film, and set a preset pattern on the PVB film by embossing to obtain a decorated PVB film;

[0015] (2) The PVB film with decoration is sandwiched between two pieces of flat glass, rolled, then heated at 130°C and then rolled, and sealed with an edge sealing agent to obtain a double layer with decoration Glass.

Embodiment 2

[0017] Provide a kind of preparation method with double-layer glass with decoration, comprising steps are:

[0018] (1) Mix polyvinyl butyral and a plasticizer, and extrude to obtain a PVB film, and set a preset pattern on the PVB film by printing and dyeing to obtain a decorated PVB film;

[0019] (2) The PVB film with decoration is sandwiched between two pieces of polished glass, rolled, then heated at 150°C and then rolled, and sealed with an edge sealing agent to obtain a double glass with decoration. layers of glass.

Embodiment 3

[0021] Provide a kind of preparation method with double-layer glass with decoration, comprising steps are:

[0022] (1) Mix polyvinyl butyral and a plasticizer, and extrude to obtain a PVB film, and set a preset pattern on the PVB film by drawing to obtain a decorated PVB film;

[0023] (2) The PVB film with decoration is sandwiched between two pieces of tempered glass, rolled, then heated at 170°C and then rolled, and sealed with an edge sealing agent to obtain a double layer with decoration Glass.

Abstract

The invention discloses a method for preparing double glass with decorations. The method comprises the following steps: mixing polyvinyl butyral (PVB) and a plasticizer, carrying out extrusion forming so as to form a PVB film, and forming preset patterns on the PVB film, so as to obtain a PVB film with decorations; sandwiching the PVB film with the decorations between two pieces of common glass, rolling, then, heating, rolling, and carrying out edge sealing with an edge sealing agent, thereby obtaining the double glass with the decorations. Through the manner, the method for preparing the double glass with the decorations, disclosed by the invention, has the advantages that the process operability is strong, large-scale production can be realized, the obtained double glass can be safely broken, a whole piece of glass still keeps integrated in case of being smashed due to heavy object impacting, and smashed blocks and sharp small chips are still stuck together with the middle film, so that the double glass is safety, the decorations are ornamental, and the double glass can play a role in decorating a service place.

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing double-layer glass with decoration. Background technique [0002] Glass is a transparent semi-solid and semi-liquid substance that forms a continuous network structure when molten, and is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. The main component of ordinary glass chemical oxide is silicon dioxide, which is widely used in buildings to prevent wind and transmit light. Ordinary annealed glass shatters when it is hit, even if it is very thick glass, it will produce many long and sharp-edged fragments, which will cause harm to people around. And now it will appear monotonous with transparent ordinary glass, and it is very troublesome to decorate on it. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a method for preparing double-layer glass with de...
