Magnetic ultra-soft X/gamma ray protective diaphragm material with decorative or directly printable function and preparation method of magnetic ultra-soft X/gamma ray protective diaphragm material

Abstract

The invention relates to a magnetic ultra-soft X/gamma ray protective diaphragm materialwith the decorative or directly printable function. The magnetic ultra-soft X/gamma ray protective diaphragm material includes a decorative or directly printable layer, an ultra-soft X/gamma ray protective material layer and a magnetic layer which are successively and tightly connected, and the ultra-soft X/gamma ray protective material is prepared from the following components in percentage by weight: 70-97% of a crystallized X/gamma ray absorption functional body, 2.8-28% of a matrix component and 0.2-2%of an addition agent, wherein the crystallized X/gamma ray absorption functional body is a crystallized compound with the median particle size D50 being more than 10 [mu]m. According to the magnetic ultra-soft X/gamma ray protective diaphragm material with the decorative or directly printable function, the decorative or directly printable and writing function, X/gamma ray protection performance and magnetic performance are combined, super flexibility, hardness, flexural stiffness, tensile strength, tear strength, corrosion resistance are achieved, and multiple breakthroughs are achieved; and human bodies are prevented from X/gamma radiation, both work and life are convenient to implement, magnet installation is achieved, carrying and transportation are convenient, volume production is easy, environmental protection is achieved, and the social significance of the magnetic ultra-soft X/gamma ray protective diaphragm material is incalculable.

Description

Technical field [0001] The invention relates to an X / γ-ray protective material, in particular to a magnetic super-flexible X / γ-ray protective film material with decoration or direct printing and a preparation method thereof. Background technique [0002] X / γ rays can penetrate a certain thickness of material, and can make fluorescent materials emit light, camera latex photosensitivity, gas ionization, and can also excite inner electrons for medical imaging, material composition analysis, safety testing, etc. The occasions are becoming wider and wider, and the importance of X / γ-ray ionizing radiation protection in life and work is self-evident. [0003] The three attenuation modes of X / γ-rays: the photoelectric effect, the Compton effect, and the electron pair effect are proportional to the fourth, first and second power of the atomic number of the substance, so the atomic number of the substance is proportional to The density of the product directly determines the quality of the s...

AI Technical Summary

Problems solved by technology

[0003] The three attenuation modes of X / γ-ray photoelectric effect, Compton effect and electron pair effect are respectively proportional to the fourth power, first power and second power of the atomic number of the substance, so the atomic number of the substance and The density of the product directly determines the quality of the substance’s X / γ-ray shielding performance. Traditional X-ray protection products are made of rigid products such as lead, tungsten, concrete, and cement. Thickness, rigidity and high density are the guarantee of safety. Carrying, The inconvenience of installation and use is obvious. The X / γ-ray protection products with real protective effect have entered ordinary families, and the daily working environment is even more unbelievable.

[0004] There are also developments of flexible products, but in order to meet the X / γ-ray protection function, there are many problems such as complex manufacturing process, high manufacturing process cost, high hardness, high material cost, not supple enough, and lead content: by adding plasticizers to The flexibility is improved, but the problem of simultaneous aging cannot be solved, and the product is easy to harden; the flexible rare earth oxide products on the market are easy to absorb moisture, and the finished product is easy to swell and bulge, and the protective properties are destroyed; the particles are small and easy to agglomerate, and cannot be mixed evenly with the binder

[0007] In the prior art, there is no magnetic ultra-soft X / γ-ray protective film material that can be decorated or directly printed.
