Technical Field

[0001] The present invention relates to the technical field of radiation protection materials, and in particular to a blackbody-like radiation protection material. Background Art

[0002] With the advancement of science and technology, the application of electromagnetic waves is becoming increasingly widespread, and the associated hazards are attracting greater attention. This applies to everything from military, nuclear power plants, and nuclear testing to everyday items like mobile phones, computers, induction cookers, and microwave ovens. Furthermore, with the further application and promotion of electromagnetic technology in electronic products, the impact of electromagnetic radiation will continue to increase, demonstrating the broad prospects for the development and application of electromagnetic protection technologies and products.

[0003] A Chinese patent with authorization announcement number CN 208421687 U discloses an anti-reflective and anti-radiation all-in-one device. The patent provides a diffuse reflection layer and an anti-radiation layer, which have the effects of preventing glare and improving light transmittance, and can also effectively reduce harm to the human body. The device intelligently senses the height of the human body through an ultrasonic sensor and adaptively raises and lowers the all-in-one device, making it easier for people of different heights to use. The device is based on Internet of Things communication technology, and users can use mobile devices to control and operate it through a wireless signal connection to the backend server.

[0004] In actual use, we found that the above patent only includes single shielding and reflection, but cannot combine the two, which greatly affects the effect of actual use. Therefore, it needs to be improved and enhanced. Therefore, we propose a blackbody-like radiation protection material. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a blackbody-like radiation protection material.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A blackbody-like radiation-proof material includes a substrate on which radiation-proof hollow spheres are embedded. The radiation-proof hollow spheres are arranged in a rectangular array and are provided with through holes for electromagnetic radiation to enter. The radiation-proof hollow spheres are used to absorb electromagnetic radiation. The radiation-proof hollow spheres consist of an inner layer, an interlayer, and an outer layer. The inner layer is a blackbody layer, the interlayer is a conductive layer, and the outer layer is a metal layer.

[0008] Preferably, the black body layer is composed of a light diffusion film layer, a black pigment coating layer, and a polytetrafluoroethylene film layer from the inside to the outside.

[0009] Preferably, a frosted layer is provided on a side of the light diffusion film layer away from the black pigment coating.

[0010] Preferably, the conductive layer consists of a first conductive adhesive layer, a conductive paint layer, and a second conductive adhesive layer in sequence from inside to outside.

[0011] Preferably, the metal layer is composed of a polyester layer, a pearlescent film layer, an adhesive layer, and an aluminum foil Mylar layer in sequence from the inside to the outside.

[0012] Preferably, a first through hole is provided on the black body layer, a second through hole is provided on the conductive layer, and a third through hole is provided on the metal layer. The through holes consist of the first through hole, the second through hole, and the third through hole which are interconnected.

[0013] Preferably, the substrate is composed of an organic glass layer and a black reflective paper layer, and the black reflective paper layer is bonded to the organic glass layer.

[0014] A method for manufacturing a blackbody-like radiation-proof material comprises the following steps: forming a conductive layer on a blackbody layer, forming a metal layer on the conductive layer on a side away from the blackbody layer, thereby obtaining raw materials for manufacturing radiation-proof hollow spheres; forming the raw materials into a hollow spherical shape, with the blackbody layer located innermost and the metal layer located outermost, thereby obtaining radiation-proof hollow spheres; providing through holes in the radiation-proof hollow spheres; providing hemispherical grooves arranged in a rectangular array on a substrate; and embedding the radiation-proof hollow spheres into the hemispherical grooves.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention is easy to manufacture; the substrate is installed at a designated position that requires radiation protection, and when electromagnetic radiation is irradiated, it will enter the interior of the radiation-proof hollow sphere through the through hole. After the electromagnetic radiation contacts the black body layer, it can be diffusely reflected on the light diffusion film layer, and the energy of the electromagnetic wave is reduced by increasing and changing the propagation path, thereby weakening or being absorbed. The frosted layer can increase the roughness of the light diffusion film layer, thereby increasing the diffuse reflection surface and improving the absorption effect; the conductive paint layer has high conductivity and high electromagnetic shielding efficiency, and has a good reflection effect; the metal layer is composed of a polyester layer, a pearlescent film layer, an adhesive layer, and an aluminum foil Mylar layer from the inside to the outside, which not only has good electromagnetic reflection ability, but also has good thermal conductivity and heat dissipation ability, and is not easy to rust.

The radiation-proof hollow spheres 2 are arranged in a rectangular array. Through holes 3 are opened on the radiation-proof hollow spheres 2, which are used for electromagnetic radiation to enter. The radiation-proof hollow spheres 2 are used to absorb electromagnetic radiation. The radiation-proof hollow spheres 2 are composed of an inner layer, an interlayer, and an outer layer. The inner layer is a blackbody layer 21, the interlayer is a conductive layer 22, and the outer layer is a metal layer 23.

[0030] Reference Figure 3 The substrate 1 is composed of an organic glass layer 11 and a black reflective paper layer 12 , and the black reflective paper layer 12 is bonded to the organic glass layer 11 .

[0031] A method for manufacturing a blackbody-like radiation-proof material includes the following steps: forming a conductive layer 22 on a blackbody layer 21, forming a metal layer 23 on the side of the conductive layer 22 away from the blackbody layer 21, thereby obtaining raw materials for making radiation-proof hollow spheres 2, and forming the raw materials into a hollow spherical shape, with the blackbody layer 21 located at the innermost side and the metal layer 23 located at the outermost side, thereby obtaining radiation-proof hollow spheres 2, opening through holes 3 in the radiation-proof hollow spheres 2, and forming hemispherical grooves arranged in a rectangular array on a substrate 1, and embedding the radiation-proof hollow spheres 2 into the hemispherical grooves.

[0032] Working principle:

[0033] During the production process, a conductive layer 22 is made on the black body layer 21, and a metal layer 23 is made on the side of the conductive layer 22 away from the black body layer 21, thereby obtaining the raw material for making the radiation-proof hollow sphere 2. The raw material is made into a hollow sphere, at this time, the black body layer 21 is located on the innermost side, and the metal layer 23 is located on the outermost side, thus obtaining the radiation-proof hollow sphere 2. A through hole 3 is opened on the radiation-proof hollow sphere 2, and hemispherical grooves arranged in a rectangular array are opened on the substrate 1, and the radiation-proof hollow sphere 2 is embedded in the hemispherical grooves.

[0034] When in use, the substrate 1 is installed in a designated position where radiation protection is required. When electromagnetic radiation is irradiated, it will enter the interior of the radiation-proof hollow sphere 2 through the through hole 3. After the electromagnetic radiation comes into contact with the black body layer 21, it can be diffusely reflected on the light diffusion film layer 213. By increasing and changing the propagation path, the energy of the electromagnetic wave is reduced, thereby weakening or being absorbed. The frosted layer 214 is provided to increase the roughness of the light diffusion film layer 213, thereby increasing the diffuse reflection surface and improving the absorption effect; the conductive paint layer 221 has high conductivity and high electromagnetic shielding efficiency, and has a good reflection effect; the metal layer 23 is composed of a polyester layer 234, a pearlescent film layer 233, an adhesive layer 232, and an aluminum foil Mylar layer 231 from the inside to the outside. It not only has good electromagnetic reflection ability, but also has good thermal conductivity and heat dissipation capabilities, and is not easy to rust.
