Figure 2 It is a schematic structural diagram showing the radiation-proof fabric used in the surface layer of the radiation-proof clothing according to an embodiment of the present invention.

[0049] The radiation protection suit according to the present invention comprises a surface layer and a substrate layer. The surface layer is made of radiation protection fabric, and the radiation protection fabric comprises a radiation protection material layer. The radiation protection suit can be used for emergency repair and rescue protection in nuclear radiation scenes, and for individual protection of repair personnel in a short time in a limited nuclear radiation environment.

[0050] Preferably, the radiation protection suit is a vest-shaped design with the vest as the overall structure, which can effectively protect key parts. More preferably, the radiation protection suit is a radiation protection vest, but the present invention is not limited thereto. For example, the radiation protection suit can also be a radiation protection vest, a radiation protection short sleeve, or a radiation protection long sleeve.

[0051] Preferably, the radiation protection suit includes a vest portion 10 as a main body and a sensitive part portion. A single layer of radiation protection material layer is used in the vest portion 10, and two or more layers of radiation protection material layers are used in the sensitive part portion. In the present embodiment, the sensitive part portion may include a neck portion 20 of the radiation protection suit corresponding to the thyroid gland of the human body. In a further embodiment, the sensitive part portion may include a crotch portion 30 of the radiation protection suit corresponding to the gonads of the human body, but the present invention is not limited thereto, and the sensitive part portion may also include the cervical vertebrae and the chest and abdomen.

[0052] In a preferred embodiment of the present invention, the vest portion 10 as the main body is a structure of two pieces, front and back, that is, it includes a front vest portion and a rear vest portion, also referred to as a front vest piece and a rear vest piece, or a vest front piece and a vest back piece. The rear vest portion increases the protection area for the back and improves the back's ability to protect against medium and low energy gamma rays, so that the front and back of the radiation protection vest can play a protective role. In a preferred embodiment of the present invention, the front vest portion and the rear vest portion are adjustably connected on the left and right sides. Preferably, the front vest portion and the rear vest portion are elastically and adjustably attached. In an embodiment, the chest and abdomen of the front outer side of the front vest portion are provided with Velcro 40, and the rear vest portion has two fixing pieces with Velcro extending from the armpits on both sides for attaching to the Velcro of the front vest portion so that the waist space can be freely adjusted to stabilize the vest. As Figure 1 As shown, the chest and abdomen of the front outer side of the front vest part have three horizontal rows of Velcro 40. By adjusting the position of the Velcro, it is not only suitable for people of various body types to wear, but also easy to put on and take off. However, the present invention is not limited to this. For example, it can have two or four rows of Velcro, or it can have multiple block-shaped Velcro, or it can have vertical rows of Velcro. The various parts of the vest are bonded and fixed with Velcro, which can be quickly put on; open the Velcro on both sides, remove the front and back pieces of the vest to complete the quick removal.

At the same time, the vest has good stability, improves protection performance, and is safe and reliable. The radiation protection vest using this embodiment can be easily and quickly put on and taken off, and has a wide range of applications.

[0053] In a preferred embodiment of the present invention, the neck is designed as an ergonomically shaped curved surface that fits the mandible to fit the neck of the wearer. This embodiment optimizes the design of the protective structure of the key part of the stand-up collar of the radiation protection vest, namely the neck 20, so that it can fit the mandible of the wearer more closely, improve the wearing comfort, and further ensure the radiation protection performance of the radiation protection clothing, and prevent protection loopholes caused by improper clothing.

[0054] In a preferred embodiment of the present invention, the radiation-proof vest of this embodiment optimizes the design of the crotch panel, and the crotch design fits the reproductive gland part, which reduces the overall weight while taking into account the radiation protection ability of the key part, namely the crotch 30. In a further preferred embodiment of the present invention, the crotch 30 of the radiation-proof vest of this embodiment is added with a hook-shaped buckle 50 for bonding to the outside, which can be bonded and fixed with the fur-shaped buckle of other equipment for convenient matching. The radiation-proof vest of this embodiment can better fit and adapt to the wearer's body, improve the wearing comfort, reduce the burden on the human body, and can further ensure the radiation-proof performance of the radiation-proof clothing on the human body, strengthen the protection of key parts, further reduce the harm to the human body, and have a good radiation-proof effect.

[0055] In an embodiment of the present invention, the radiation protection fabric comprises a high-strength flame-retardant fabric layer, an inner lining layer, and a radiation protection material layer located between the flame-retardant fabric layer and the inner lining layer.

[0056] like Figure 2 As shown, the radiation-proof fabric according to the present invention is composed of an inner lining layer, a radiation-proof material layer, and a high-strength flame-retardant fabric layer from the inside to the outside. In a preferred embodiment of the present invention, the inner lining layer includes a flame-retardant mesh cloth. Preferably, the radiation-proof fabric is composited by a flame-retardant lining cloth, a radiation-proof material layer, and a flame-retardant base cloth. In particular, the radiation-proof fabric is made by a calendering method, that is, a high-strength flame-retardant fabric is used as the base cloth, a lead-free shielding agent and a flame retardant are dispersed in a polymer, a certain thickness is scraped on the base cloth, and then dried, and then laminated with the flame-retardant lining cloth, thereby forming a high-performance flexible radiation-proof material. Therefore, the radiation-proof fabric can be produced in large quantities and with high quality, with high production effect, and can achieve precision dimensional control of the product, while improving the physical and mechanical properties and bending resistance of the material, and having high cost-effectiveness. The outer base cloth uses a high-strength flame-retardant fabric as the skeleton material, which has the functions of high strength, light weight, flame retardancy, etc. The inner protective lining cloth uses a floating yarn mesh cloth, which has the functions of light weight, flame retardancy, etc., so the radiation-proof fabric has good flame retardancy and wear resistance. In the present invention, a lead-free shielding agent is used to avoid the potential harm of lead to human health and the environment, has improved safety and economy, is light in weight, flexible and comfortable, and can be applied to multiple fields such as medicine, industry, nuclear energy, aerospace, etc., and is used to protect personnel and equipment from radiation damage in various fields.

In a more preferred embodiment of the present invention, the flame retardant is a bromine antimony flame retardant. Therefore, the radiation-proof fabric has excellent flame retardancy and fire resistance, high flame retardant efficiency and high cost performance. Compared with other types of flame retardants, the required addition amount is less and the effect on the mechanical properties of the material is small, thereby further improving the mechanical properties of the material.

[0060] In a preferred embodiment of the present invention, the flame retardant fabric layer and the flame retardant mesh fabric include one or more of aramid, nylon, and PE. The radiation-proof fabric according to the present invention has the advantages of high flexibility, strong radiation-proof effect, wear resistance, flame retardancy, and light weight.

[0061] In a preferred embodiment of the present invention, the substrate layer includes one or more of aramid, nylon, and PE.

[0062] Therefore, the radiation protection clothing according to the present invention has the advantages of high flexibility, strong radiation protection effect, wear resistance, flame retardancy, light weight, etc. Moreover, in actual production, the radiation protection clothing according to the present invention has high production efficiency, relatively low production cost, excellent performance in all aspects, high safety, and long service life.

[0063] In a preferred embodiment of the present invention, the flexible radiation-proof fabric of the radiation-proof clothing is made of a mixture of natural rubber, lead-free shielding agent and bromine-antimony flame retardant, with high-strength flame-retardant fabric as the base fabric and bonded with a flame-retardant lining cloth. It mainly uses high atomic number micro-nano metals such as tungsten powder and tantalum to shield rays in the energy range above 88keV, and uses low atomic number micro-nano metals such as tin powder to shield scattered photons from the radiation source, thereby achieving a comprehensive radiation protection effect with a wide protection range and a strong radiation protection effect.

[0064] In a preferred embodiment of the present invention, the thickness of the radiation protection fabric is between 0.5 mm and 5.0 mm, thereby achieving a light, lightweight, flexible radiation protection suit, which provides the wearer with improved comfort.

[0066] When wearing the radiation protection vest according to the present invention, the wearer adopts a pullover style, which is convenient and quick. At the same time, through the internal interface designed mainly for the connection port of a single garment and the external interface designed mainly for effective close connection with other products, quick and effective connection adjustment can be achieved, so that the radiation protection vest can be worn comfortably and quickly put on and taken off, and radiation protection loopholes caused by the radiation protection clothing not fitting the body shape can be prevented.

[0067] In a preferred embodiment of the present invention, when wearing a radiation protection vest, three rows of Velcro fasteners 40 are arranged on the waist and abdomen, and a long strip adjustment piece extending from the front shoulder of the radiation protection vest goes around the shoulder and extends from the armpit to the front abdomen, and the Velcro fasteners are used to fit the two sides of the front abdomen to connect the internal interface of a single garment.

[0068] In a further preferred embodiment of the present invention, when the radiation protection vest is worn, the hook-and-loop fastener 50 at the crotch portion 30 is used to perform an external interface connection for effective close fitting with other products.
