Problems solved by technology

However, laminated glass has high infrared transmittance in sunlight and poor energy-saving effect.
[0003] Glass is an important building material. With the continuous improvement of decorative requirements for buildings, the use of glass in the construction industry is also increasing. For example, the distribution of utility model patents with patent numbers 200920039857.9 and 201020146361.4 discloses the corresponding laminated glass These laminated glasses have the limitations of insufficient glass strength, inconspicuous heat insulation effect, and difficulty in resisting light radiation.
[0004] There are many patent applications for the process of preparing laminated glass, but the laminated glass produced by the disclosed technology has the following defects: 1. Bubbles and degumming often occur in the laminated glass; 2. The production equipment is too complicated, which makes the production cost high ; 3. The edge of the laminated glass is easy to seep into rainwater or moisture in the air, which makes the degumming phenomenon more serious; 4. The variety of laminated glass is single

Embodiment 1

[0028] Embodiment 1 Transparent composite sheet and its preparation method (1)

[0029] The glass in this embodiment is float glass with a thickness of 4 mm; the thermoplastic resin plate is polystyrene (PS) with a thickness of 3 mm; the film is EVA with a thickness of 0.76 mm.

[0030] (1) Pretreatment: Dry the PS board in an oven at 50°C for 100 minutes, then cool it down to room temperature naturally in the oven;

[0031] (2) Clean the ordinary glass, air dry it, and wipe it with a dust-free cloth;

[0032] (3) Combine common glass, EVA film and PS board in a clean room, see figure 1 . Lamination conditions are: temperature 25°C, humidity <30%;

[0033] (4) After assembling, put the sample in a vacuum bag, and carry out composite molding in a glass vacuum heat-sealing folder. Process parameters: preheat at a low temperature of 50°C for 40 minutes, then heat at a high temperature of 75°C for 110 minutes, and a pressure of 0.092MPa;

Embodiment 2

[0036] Embodiment 2 transparent composite sheet and its preparation method (2)

[0037] The glass in this embodiment is ordinary float glass with a thickness of 3 mm, the thermoplastic resin plate is polycarbonate (PC), 2 mm; the film is EVA, 1.52 mm.

[0038] (1) Pretreatment: Dry the PC board in an oven at 70°C for 90 minutes, and naturally cool it to room temperature in the oven;

[0039] (2) Clean the ordinary glass, air dry it, and wipe it with a dust-free cloth;

[0040] (3) Combine ordinary glass, EVA film and PC board in a clean room. First place the glass flat, lay the film on the upper layer, place the thermoplastic resin plate on the film, and then lay the film on the upper layer of the thermoplastic resin plate. Finally, place the glass; the three-layer board needs to be laid flat, and the film needs to be laid flat. Lamination conditions are temperature 25°C, humidity <30%;

Abstract

The invention relates to a transparent composite board and a preparation method thereof. The composite board comprises glass, a thermoplastic resin board and a rubber sheet, wherein the rubber sheet is PVB (Polyvinyl butyral), EVA (Ethylene / vinyl acetate) or PU (Polyurethane); and the thermoplastic resin board is a transparent resin board which can be polycarbonate (PC), polystyrene (PS), polymethylmethacrylate (PMMA), polyethylene (PE) or the like. The preparation method comprises the following steps of: stoving the thermoplastic resin board, laminating the thermoplastic resin board, the glass and the rubber sheet together, carrying out low-temperature preheating in a vacuum molding furnace, carrying out high-temperature composite molding, and finally cooling to obtain the transparent composite board. The transparent composite board has the advantages that the light transmittance can reach 90-92%, the impact force can reach 4kg / cm<3> at most, the stabile physical indexes are maintained in a temperature range from 40 DEG C below zero to 120 DEG C, the sound and heat insulation properties are good, and the market application prospect is good.

Description

technical field [0001] The invention relates to the field of materials, in particular to a transparent composite plate and a preparation method thereof. Background technique [0002] Laminated glass is made by pasting two or more pieces of glass under certain temperature and pressure with film, also known as laminated glass or laminated glass. The film is usually a film such as PVB (Polyvinyl butyral, polyvinyl butyral). When the glass is violently impacted and exploded, the tough PVB film will absorb most of the impact energy and shock wave pressure and prevent the impact object from penetrating, so it has anti-theft, bullet-proof, and explosion-proof functions; even if the laminated glass is damaged, the glass fragments will be securely Adhering to the PVB film, it will not fall off and hurt people, so it is especially suitable for the front windshield of automobiles and high-rise building glass; the PVB film in the laminated glass can also absorb more than 99% of ultravi...
