Example Embodiment

[0009] The present invention will be further explained below in combination with specific embodiments, but the protection scope of the present invention is not limited.

[0010] A new type of flexible lead-free radiation protective clothing. The surface of the protective clothing is provided with a protective layer. The protective layer is made of a matrix material and a filling cylinder mixing process and a calendering process. The matrix material includes a silane coupling agent and an antioxidant. Agent, polyvinyl alcohol, rubber softening oil, dioctyl resin, polyethylene rubber prepolymer, the filler includes tantalum powder, tungsten powder, iron powder, platinum powder.

[0011] The fillers are modified, dried, and ground in sequence. The grinded tantalum powder has a particle size of 4 to 5um; tungsten powder has a particle size of 4 to 5um; iron powder has a particle size of 1 to 5um; and platinum powder has a particle size of 1 to 5um. The base material is made into a base...

Abstract

The invention discloses novel flexible lead-radiation-free protective clothing. A protective layer is arranged on the surface of the protective clothing, the protective layer is made of a base material and filler through the drum mixing technology and the rolling technology, the base material comprises a silane coupling agent, an antioxidant, polyvinyl alcohol, rubber softening oil, dioctyl esterand a polyethylene rubber prepolymer, and the filler comprises tantalum powder, tungsten powder, iron powder and platinum powder. The protective clothing has the advantages that the design is reasonable, the structure is simple, tantalum, tungsten, barium and other non-toxic and environment-friendly materials are utilized to serve as the functional filler, and the material attenuation coefficient,gamma/X ray shielding performance and radioactivity of tantalum and tungsten are equivalent to those of lead so that radiation hazards can be effectively protected. According to the method, through the scientific ratio of various functional elements, and the defect, related to energy absorption, of a single functional material is corrected and overcome; besides, tantalum, tungsten, barium and thelike serve as the shielding material, the weight of the shielding material is only one fifth that of traditional lead clothes, the protective clothing is more comfortable for users, moving of hands and feet is facilitated, and the heat dissipation performance is good.

Description

technical field [0001] The invention belongs to the field of protective equipment, and in particular relates to a novel flexible lead-free radiation protective clothing. Background technique [0002] All objects in nature, as long as the temperature is above absolute temperature zero, transmit heat outward in the form of electromagnetic waves. This way of transmitting energy is called radiation. The energy released by an object through radiation is called radiant energy. Radiation is calculated in roentgen / hour (R). Radiation can be divided into particle radiation and electromagnetic radiation. Particle radiation includes neutron radiation, proton radiation, and electron radiation. Electromagnetic radiation is divided into X-rays, ultraviolet rays, and microwave radiation. These radiations are more harmful to the human body. Among them, electromagnetic wave radiation and neutron radiation are more difficult to protect. Radiation protective clothing made of lead is generall...
