Technical Field

The utility model relates to a Mini LED shows that touch screen dress pastes technical field, specifically is a simple and easy wall mounting is laminated completely and is easily torn easily and shell structure on display screen.

Background

Laminated glass is a glass widely used in the field of architectural glass, which is also called safety glass. Laminated glass, as the name implies, is a glass consisting of a plurality of layers, except for the glass, which is left as an intermediate layer in the glass, in general there being three types of layers: EVA, PVB and SGP.

Among them, PVB interlayer is an interlayer material that is widely used in current architectural glass and automotive glass. The PVB interlayer has a more complicated storage process and processing mode than EVA and has higher requirements on temperature and humidity. When PVB is processed and laminated, the temperature is required to be controlled between 18 ℃ and 23 ℃, the relative humidity is controlled between 18 percent and 23 percent, the PVB keeps 0.4 percent to 0.6 percent of water content, after the process of preheating, rolling or vacuumizing, an autoclave is used for heat preservation and pressure maintaining, and the temperature of the autoclave is as follows: 120 ℃ and 130 ℃, pressure: 1.0-1.3MPa, time: 30-60 min. A PVB plant requires about 100 million. PVB has good safety, sound insulation, transparency and ultraviolet resistance, but PVB has poor water resistance and is easy to be stripped and shed when being in a humid environment for a long time.

And EVA is known as ethylene-vinyl acetate copolymer. Because of strong water resistance and corrosion resistance, the coating is widely applied to the fields of packaging films, functional greenhouse films, foaming shoe materials, hot melt adhesives, wires and cables, toys and the like. EVA is also used as an interlayer of laminated glass, has high cost performance, and compared with PVB and SGP, EVA has good fluidity and low melting temperature, and can be processed when the temperature reaches about 110 ℃. The whole set of production equipment only needs about 10 ten thousand yuan.

The EVA film has good fluidity, and can be subjected to processes such as wire clamping, wire clamping and the like in the film to manufacture beautiful decorative glass with patterns and decorative patterns. EVA has good water resistance, but has weak ultraviolet resistance, and is easy to yellow and black after being exposed to the sun for a long time, so that the EVA is mainly used for indoor partition.

For the high-performance interlayer material SGP, it is called ionic intermediate film (sentryglassplus). The high performance is embodied as follows: excellent mechanical performance and high strength. Under the same thickness, the bearing capacity of the SGP interlayer is 2 times that of PVB; the bending deflection of the SGP laminated glass is one fourth of that of PVB at the same load and thickness. Tear strength. Under the same thickness, the tearing strength of the PVB laminated film is 5 times that of PVB, and the PVB laminated film can be bonded on glass under the tearing condition, so that the whole glass cannot fall off. High stability and high resistance to moisture. The SGP laminated film is colorless and transparent, is ultraviolet-resistant, is not easy to yellow after being exposed to the sun and rain for a long time, and has the yellowing coefficient less than 1.5, while the PVB laminated film has the yellowing coefficient of 6-12. SGP is therefore a pet for ultrawhite laminated glass. Although the production process of SGP is close to PVB, the terminal price is high.

Aiming at the direct wall-mounting design of PVB developed by the existing company, the wall-mounting and dismounting actions can be easily realized by matching with the wall-mounting liquid medicine developed by the PVB. However, if the wall-mounting material is made of EVA, the EVA is very stable, and thus wall-mounting and dismounting operations cannot be realized by matching with wall-mounting chemicals. The following table one shows the thermal expansion coefficients of Glass (Glass) and plastic materials commonly used for laminated Glass, and the thermal expansion coefficients of Glass (Glass) and Glass (Glass) are higher than those of Epoxy resin (Epoxy) and Acrylic resin (Acrylic); therefore, only the symmetrical hot-pressing and laminating operation can be used, the asymmetrical simple wall mounting operation cannot be realized, and the shrinkage and the warping are easily caused by the cold pasting method in particular.
