Problems solved by technology

The traditional installation method is to punch holes in the glass, insert the edge into the frame, glue and bond. Due to the existence of frames and glue, the entire glass surface is divided, which cannot perfectly reflect the transparent effect, which greatly reduces its integrity

[0026] A preparation process of laminated glass with pre-embedded metal parts, the steps are as follows:

[0027] Step 1. According to the size of the pre-embedded metal part 1, process a gap in the interlayer glass 4, place the metal part 1 on the gap 6 of the interlayer glass, and fill the gap between the metal part 1 and the gap 6 in the interlayer glass with film 5. Spare;

[0028] Step 2: Lay the outer glass 2, the intermediate glass and the inner glass 3 prepared in step 1 together to form a glass assembly, lay film between the intermediate layer and the outer layer, and between the intermediate layer and the inner layer, and pull out the gap of the glass assembly The air, then heated and pre-pressed to make the glass components initially bonded into a semi-finished product of an integrated structure, ready for use;

[0029] Step 3. Place the semi-finished product that is initially bonded into an integrated structure in an autoclave. After the treatment of the heating a...

Embodiment 1

[0042] Step 1. According to the size of the pre-embedded metal parts, use the CNC machining center to process a gap in the interlayer glass, place the metal part in the gap, fill the gap between the metal part and the interlayer glass gap with SGP film, and set aside;

[0043]Step 2: Lay the outer layer of glass, the prepared intermediate layer of glass and the inner layer of glass together to form a glass assembly, lay SGP film between the intermediate layer and the outer layer, and between the intermediate layer and the inner layer, and place the stacked glass assembly as a whole Put it in a sealed vacuum bag, use a vacuum pump to connect the vacuum bag and pump out the air in all the gaps in the glass assembly, then heat it to 110°C, and pre-press the semi-finished product to make the glass assembly initially bonded into an integrated structure, ready for use;

[0044] Step 3. Place the semi-finished products that are initially bonded into an integrated structure in an autoc...

Embodiment 2

[0050] Step 1. According to the size of the pre-embedded metal parts, process a gap in the interlayer glass, place the metal part in the gap, fill the gap between the metal part and the interlayer glass gap with film, and set aside;

[0051] Step 2: Lay the outer layer of glass, the prepared intermediate layer of glass and the inner layer of glass together to form a glass assembly, lay film between the intermediate layer and the outer layer, and between the intermediate layer and the inner layer, extract the air in the gap of the glass assembly, and then Heated to 115°C and pre-pressed to make the glass components initially bonded into a semi-finished product with an integrated structure, ready for use;

[0052] Step 3. Place the semi-finished products that are initially bonded into an integrated structure in an autoclave, and go through three stages of treatment:

[0053] Heating and pressurization stage: the semi-finished product is put into the autoclave, the initial pressu...

Abstract

A preparation process of laminated glass with an embedded metal part comprises the following steps that a notch is machined in middle-layer glass according to the size of the embedded metal part, themetal part is placed at the notch, and a gap between the metal part and the notch of the middle-layer glass is filled with a film; the outer-layer glass, the prepared middle-layer glass and the prepared inner-layer glass are stacked together to form a glass assembly, films are laid between the middle layer and the outer layer and between the middle layer and the inner layer, air is pumped out in gaps of the glass assembly, and then heating and pre-pressing are carried out to enable the glass assembly to be preliminarily bonded into a semi-finished product of an integrated structure; and the semi-finished product is out into a high-pressure kettle, and treatment of a heating and boosting stage, a heat preservation stage and a cooling stage is conducted to finish the preparation. According to the process, a metal part is pre-embedded into middle laminated glass, and meanwhile, through heating and pre-pressing forming and in combination with treatment of a heating and boosting stage, a heat preservation stage and a cooling stage in a high-pressure kettle, multiple layers of glass and the metal part are bonded into the integrally transparent laminated glass with the pre-embedded metalpart.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a preparation process of laminated glass with pre-embedded metal parts. Background technique [0002] As we all know, laminated glass is a composite glass that separates glass from glass with an interlayer and bonds them together through treatment. The interlayer between the glass mostly uses PVB or SGP. Multilayer laminated glass can be produced by combining multiple layers of glass and multiple interlayers. As a type of safety glass, laminated glass is mostly used in curtain wall panels, ceilings, glass ribs, railings, floors, etc. in buildings. The end surface of the finely processed multi-layer laminated glass can be smooth and transparent. The traditional installation method is to punch holes in the glass, insert the edge into the frame, glue and bond. Due to the existence of frames and glue, the entire glass surface is divided, which cannot perfectly refle...
