Description

Technical Field

[0001] The invention relates to the technical field of glass preparation, and in particular to a special multifunctional glass with magnetic shielding and shock resistance. Background Art

[0002] Polymethyl methacrylate is an organic compound, which is mainly used as a monomer of organic glass, used to make materials such as plastics, coatings, lubricants, impregnation agents and resins. It is also the main raw material of lead glass. Traditional lead glass can radiate gamma rays to a certain extent, but in special fields (civil air defense projects, cold and hot critical spaces), the durability of traditional lead glass cannot be effectively guaranteed (brittleness and strong ionization and deterioration of silica). And because the glass itself absorbs electromagnetic radiation, it is easy to change color and lose transparency. Therefore, during the operation, effective measures need to be taken to avoid such problems or extend the replacement cycle.

[0003] Radiation-proof glass is often used in radioactive waste solidification treatment, nuclear medical equipment, ray detection and other devices. In space, nuclear power plants and other scientific application fields, radiation-proof glass mainly has a large absorption capacity for gamma rays, X-rays, etc. When gamma rays or X-rays enter the radiation-proof glass, due to the photoelectric effect inside the glass, positive and negative electron pairs are generated, and excited and free electrons are generated at the same time, which reduces the energy of the incident gamma rays or X-rays and reduces the penetration, thus playing a protective role. However, photons and particle radiation in the irradiation environment can cause glass ionization, thereby changing the transmittance of the glass. It is generally believed that radiation resistance represents the most prominent requirement for glass materials in extreme environments such as space and nuclear radiation. The radiation resistance of radiation-proof glass in the prior art is poor. After being used in a radiation environment for a certain period of time, the transmittance decreases significantly, affecting the product's use effect and service life.

[0004] At present, the observation windows of large-scale detection equipment such as MRI, CT and DR use existing anti-magnetic radiation glass, which has the disadvantages of high brittleness, high carrier requirements, poor plasticity, low critical difference between cold and hot, and easy to burst. The existing glass cannot fully meet the needs. The large-scale instruments have extremely high requirements on the radiation protection and seismic resistance of the glass, and its transparency must meet the requirements, and the service life and use effect must be extended. Based on this, the present invention proposes a special multifunctional glass with magnetic shielding and seismic resistance. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a special multifunctional glass with magnetic shielding and shock resistance. In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A special multifunctional glass with magnetic shielding and shock resistance, which includes, from the critical surface, a polymethyl methacrylate layer, a short-wave liquid crystal silver ion liquid crystal film layer, a silicon dioxide high-barium optical glass layer, a silicon dioxide tungsten silver ion liquefied layer, a nickel wire mesh layer and a polymethyl methacrylate layer;

[0007] The polymethyl methacrylate layer close to the critical surface is doped with 1% samarium ions; the preparation method thereof adopts compression hot-melt lamination.

[0008] Preferably, a protective frame is arranged on the outer sides of the multifunctional glass, and the protective frame includes two support rods and two cross rods. Slide grooves are arranged in the two support rods, and one of the cross rods is provided with a through groove. The nickel wire mesh layer passes through the through groove, and both sides of the nickel wire mesh layer are respectively arranged in the slide grooves.

[0009] Preferably, a hand-held portion is provided on the nickel wire mesh layer outside the through groove, and a sliding block is provided in the slide groove, and the sliding block is connected to the end of the nickel wire mesh layer.

[0010] Preferably, the process conditions of the compressed hot melt interlayer are: 350-1200° C. in an air atmosphere, keeping warm for 1-2 hours, and then cooling to room temperature.

[0011] Preferably, an automatic receiving module is provided in the short-wave liquid crystal silver ion liquid crystal film layer, which is electrically connected to the power supply. When the magnetic induction exceeds a set rated value, the short-wave liquid crystal silver ion liquid crystal film layer will change color.

[0012] Preferably, the nickel wire mesh layer is used for the application of the rated equipment voltage during the debugging process after transportation. The nickel wire mesh is arranged inside the glass product shell and has the functions of shielding electromagnetic radiation, resisting electromagnetic wave interference, and demagnetizing.

[0013] Preferably, the thickness of the polymethyl methacrylate layer close to the critical surface is 22-25 mm; the thickness of the short-wave liquid crystal silver ion liquid crystal film layer is 1-3 mm.

[0014] Preferably, the thickness of the silica high-barium optical glass layer is 4-6 mm; the thickness of the silica tungsten silver ion liquefied layer is 15-18 mm; and the thickness of the nickel wire mesh layer is 1-3 mm.

[0015] Preferably, the thickness of the polymethyl methacrylate layer away from the critical surface is 15-20 mm.

[0016] In summary, since the present invention adopts the above technical solution, the present invention has the following technical effects:

[0017] 1. The present invention can control electromagnetic radiation corrosion and ionization discoloration by doping 1% samarium ions in polymethyl methacrylate near the critical surface. The short-wave liquid crystal silver ion liquid crystal film belongs to the plasma control of the yin and yang diodes. The transparent perception is reduced as much as possible during operation to further reduce radiation. The silicon dioxide high-barium optical glass serves as a conventional light-transmitting function, and the silicon dioxide tungsten silver ion liquefied layer blocks 75% of short-wave gamma rays. The manual nickel wire mesh can respond to emergencies and radiation protection measures under maintenance status.

[0018] 2. The multifunctional glass of the present invention has a strong electromagnetic radiation resistance. By adding a short-wave liquid crystal silver ion liquid crystal film in the polymethyl methacrylate interlayer, an automatic receiving module is provided in the short-wave liquid crystal silver ion liquid crystal film, which is electrically connected to the power supply. When the magnetic induction exceeds the set rated value, the short-wave liquid crystal silver ion liquid crystal film layer will change color (such as turning black), and the silicon dioxide tungsten silver ion liquefied layer can make the light maintain its transmittance after being used in a radiation environment for a certain period of time, and block the glass from producing a photoelectric effect, thereby increasing its service life.

[0019] 3. The present invention not only enhances the magnetic shielding function of the glass by adding multiple layers of glass material between two polymethyl methacrylate layers, but also the silica high-barium optical glass layer and the silica tungsten silver ion liquefied layer have high strength and good flexibility, which enhance the seismic resistance of the glass. A protective frame is added to the outside of the glass to improve the seismic resistance of the glass around. The internal material of the glass is added with a combination of metal material and protective frame, which further improves the seismic resistance of the glass. BRIEF DESCRIPTION OF THE DRAWINGS
