Description
Technical field
The present invention relates to radiation protection technical field, more particularly, to a kind of lead-free anti-ray material.
Background technology
The scientific utilization of ray brings immeasurable benefit for scientific and technological progress, economic development and the health and civilization of society
Place.But relevant occupational area is radiated with ray, such as the exploitation of core ore deposit, refinement, segmentation, packaging, transport；Nuclear Power Station is set
Installation, the operation applied；Radioimmunodiagnosis, analysis；Radiotherapy, industrial flaw detection, the making of radiation imaging apparatus, operation；With
And Military Application etc., the measure for the ray that is required for properly protecting to staff.
So far, in terms of the equipment of individual protection, the radiation shielding material still continued to use both at home and abroad is lead rubber system
Product, i.e., add in the lead powder of 100~400 mesh in the rubber of melting, it is agitated, rub pressure after be pressed into plate (skin) shape, then by design punching,
After cutting, surrounding is wrapped in common cloth, is spliced into protective garment.Such material and correlated product have following technological deficiency：
(1) viscous pasty state after being heated due to rubber, lead button or lead compound monomer are difficult to be uniformly dispersed in rubber,
The harmony of shield effectiveness is impacted.(2) protective garment is thick and heavy, and dress is uncomfortable, and work efficiency is poor, by taking 0.35Pb as an example, protective garment weight
For：3.75kg, in addition head protector, protector for collar, gloves, leg protector, the weight of a whole set of protector is up to more than 10 jins.(3) in lead rubber
Lead molecule can be precipitated from rubber, and lead is toxic to human body.Meanwhile discarded lead rubber can cause it is irreversible
Environmental pollution.(4) in lead rubber slab (skin), lead content is higher, and its physical property is poorer, and lead rubber slab can be caused by squeezing repeatedly
The fracture of (skin), being especially secretly broken (the middle fracture for referring to offset plate), this will be great security risk to occupational staff.In addition,
In natural environment, lead rubber is easy to aging, if folding, standing time is slightly longer, and safety device easily deforms, it is difficult to be continuing with.
CN2129961 provides a kind of low energy radiation protective metal fabric, the metal cladding in textile cloth, thickness of coating 5
~20 microns, but the energy of below 30KeV can only be protected to radiate.CN103824605A discloses a kind of unleaded anti-ionising radiation
Composite material, comprising radiation protection powder body material and moulding material, the powder body material include blanc fixe, brown iron oxide, tungsten and
Its compound and cadmium and its compound；But this technology can only prepare the hard radiation protection material such as barrier, wall, door, rubber
Material can not make soft clothing and be through on human body.CN106307743A, which provides a kind of multifunctinal antiradiation maternity dress, to be included
The outer layer of internal layer and coating extruded on internal layer；Internal layer is metallic fiber and the blended manufactured fabric of textile fabric；Outer layer is containing metal
Or the coating of its oxide；The metal is selected from tungsten or bismuth, coating layer thickness 0.05-0.50mm；But prepared by this technology
Radiation-proof fabric is not washable, and radiation proof material will come off after washing several times.
