Leadless anti-radiation material and preparation method thereof

Abstract

The invention provides a leadless anti-radiation material and a preparation method thereof. The preparation method comprises: mixing and stirring methacrylic acid and deionized water at first; adding nano gadolinium oxide and nano samarium oxide; performing heating and stirring until the solution is clarified; performing filtration; performing reduced pressure distillation on the filtrate to remove water; then performing cooling in a refrigerator; performing suction filtration, and then drying filter residues to obtain a product; mixing the product with methyl methacrylate, azobisisobutyronitrile, azobisisoheptonitrile, dibutyl phthalate, diisopropyl peroxy dicarbonate, bismuth oxide, stearic acid, propylene glycol, hydroxyethyl methylacrylate, styrene and anhydrous ethanol; putting the mixture into an oil bath pan for heating reaction; performing filtration to remove insoluble substances and the like; cooling liquid to room temperature; pouring the liquid into a mold; standing the liquid in a drying oven; then performing heating and heat preservation; and performing cooling to obtain the leadless anti-radiation material. The leadless anti-radiation material provided by the invention is transparent and attractive in appearance, is strong in solvent resistance, and has a very high light transmittance at the same time, and most importantly, the leadless anti-radiation material can effectively absorb X rays and is high in radiation resistance.

Description

technical field [0001] The invention relates to the field of materials, in particular to a lead-free anti-radiation material and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, various electronic devices have become an indispensable part of people's production and life, and the accompanying hazards are irrelevant radiation. As we all know, people who are often exposed to rays will have some adverse symptoms, such as hair loss. , burning and even endangering the health of the human body, therefore, the research and development of anti-radiation materials is of great significance for the protection of human health and safety. Anti-radiation materials refer to materials that can absorb or dissipate radiation energy and protect the human body or equipment. Generally, the anti-radiation materials we use contain lead, but lead is heavy, opaque, expensive and complicated. Therefore, the development of a lead-free, l...
