Description
Technical Field
The invention relates to the technical field of ray protection, in particular to a lead-free ray-proof material.
Background
The scientific utilization of rays brings immeasurable benefits to the scientific and technological progress, economic development and health culture of the society. However, occupational areas associated with radiation, such as the exploitation, extraction, segmentation, packaging, transportation of nuclear mines; installing and operating nuclear facilities of a nuclear power station; performing radioimmunoassay and analysis; manufacturing and operating radiotherapy, industrial flaw detection and radiographic imaging equipment; and military applications and the like, the radiation protection measures for workers are required.
Until now, in the aspect of individual protection equipment, the ray shielding material still used at home and abroad is a lead rubber product, namely 100-400 meshes of lead powder is added into melted rubber, the mixture is stirred, kneaded and pressed to be pressed into a plate (skin) shape, and then the plate (skin) shape is punched and cut according to the design, and common cloth is wrapped around the plate to be spliced into the protective clothing. The materials and the related products have the following technical defects:
(1) Due to the viscous state of the rubber after heating, lead particles or lead compound monomers are difficult to be uniformly dispersed in the rubber, and the balance of the shielding effectiveness is affected. (2) The protective clothing is heavy, uncomfortable to wear, and has poor working effect, taking 0.35Pb as an example, the weight of the protective clothing is as follows: 3.75kg, and a protective cap, a protective collar, gloves and a leg protector are added, and the weight of the whole protective protector is 10 jin. (3) Lead molecules in the lead rubber can be separated out from the rubber, and lead is toxic to human bodies. Meanwhile, the waste lead rubber can cause irreversible environmental pollution. (4) The lead rubber plate (skin) has poor physical properties due to higher lead content, and the repeated extrusion can cause the fracture of the lead rubber plate (skin), especially the dark fracture (meaning the fracture of the rubber plate), which is a great safety hazard for professionals. In addition, lead rubber is easily aged in natural environment, and if the lead rubber is folded and left for a long time, the protective tool is easily deformed and difficult to continue to use.
CN2129961 provides a low-energy radiation protection metal cloth, wherein a metal layer is plated on a textile cloth, the thickness of the plating layer is 5-20 micrometers, but the low-energy radiation protection metal cloth can only protect energy radiation below 30 KeV. CN103824605A discloses a lead-free anti-ionizing radiation composite material, which comprises an anti-radiation powder material and a molding material, wherein the powder material comprises barium sulfate powder, iron oxide powder, tungsten and compounds thereof, and cadmium and compounds thereof; however, the technology can only prepare hard radiation-proof materials such as barriers, walls, doors, rubber and the like, and cannot be made into soft clothes to be worn on a human body. CN106307743A provides a multifunctional radiation-proof maternity dress which comprises an inner layer and an outer layer coated on the inner layer; the inner layer is a fabric made by blending metal fibers and textile fibers; the outer layer is a coating containing metal or oxide thereof; the metal is selected from tungsten or bismuth, and the thickness of the coating is 0.05-0.50mm; however, the radiation-proof fabric prepared by the technology is not washable, and the radiation-proof material can fall off after being washed for several times.

TABLE 1
| Lead rubber | Tungsten metal cloth (implementation)Example 3) | |
| Weight (D) | 3.75kg | 1.24kg |
| Thickness of material | 2mm | Less than or equal to 750 mu m |
| Whether or not it is toxic | Is provided with | Is free of |
| Comfort of wearing | Difference (D) | Good quality |
| Shielding structure | In general | Superior food |
| Age of use | 3-4 years old | More than five years |
| Lead equivalent | 0.35mmPb | 0.35mmPb |
As can be seen from the comparison in Table 1, the thickness of the tungsten metal cloth is only 700 μm at most, while the thickness of the lead rubber sheet is as high as 4 to 5mm, i.e., the former is 1/4 to 1/5 of the latter. The weight of the former is 1/3 of the weight of the latter when the protective clothing with the same style and the same lead equivalent is prepared by using the tungsten metal cloth.
