Super-flexible X/gamma ray protection membrane material with decoration or direct printing function and preparation method of material

Abstract

The invention relates to a super-flexible X / gamma ray protection membrane material with a decoration or direct printing function. The material comprises a decoration or direct printing layer and a super-flexible X / gamma ray protection material layer which are tightly connected or comprises a decoration or direct printing layer, a super-flexible X / gamma ray protection material layer and a decoration or direct printing layer which are tightly connected in sequence; the super-flexible X / gamma ray protection material comprises 70-97wt% of a crystallized X / gamma absorption functive, 2.8-28wt% of amatrix composition and 0.2-2wt% of an additive; the crystallized X / gamma absorption functive is a crystallized compound with the meso-position particle size larger than 10 microns. According to the material, combination of the direct printing function and the X / gamma ray protection function is achieved, the human body is protected from X / gamma ray radiation, the material is convenient to use during work and life, easy to produce in batch and environmentally friendly, and the social meaning of the material is immeasurable.

Description

technical field [0001] The invention relates to an X / γ-ray protective material, in particular to a super-soft X / γ-ray protective film material with decoration or direct printing and a preparation method thereof. Background technique [0002] X / γ-rays can penetrate materials with a certain thickness, and can make fluorescent materials emit light, photosensitive latex of cameras, and ionize gases, and can also excite inner layer electrons, which can be used in medical imaging, material composition analysis, safety testing, etc. With more and more occasions, the importance of X / γ ionizing radiation protection in life and work is self-evident. [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 X / γ shielding perf...

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 X / γ shielding performance of the material. Traditional X / γ ray protection products are made of rigid products such as lead, tungsten, concrete, cement, etc. Thick, rigid and high density are the guarantee of safety. , Installation, and use are obviously inconvenient. X / γ-ray protection products with real protective effects 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

[0005] The authorized announcement number is 207449316U, the patent name is "A Directly Printable Magnetic Paper Product", the authorized announcement number is 204659065U, and the patent name is "A Printable Soft Magnetic Composite Structure". Solve the combination of printable and magnetic functions, which is convenient for magnetic installation, flexible and easy to carry and store, but none of them have X / γ-ray protection function
