preparation example Construction

[0053] A second aspect of the present invention provides a method for preparing the radiation-resistant composite material, which includes the following steps:

[0054] (1) Mix bismuth trioxide, filler and polyacrylate, and grind to obtain radiation shielding filler slurry;

[0055] (2) adding the radiation shielding filler slurry into the liquid rubber, stirring to obtain a mixed emulsion;

[0056] (3) Dipping and molding the mixed emulsion to obtain the product.

[0057] In one embodiment, the grinding is dry grinding and / or wet grinding.

[0058] Preferably, the grinding is wet grinding.

[0059] In one embodiment, the grinding time of the grinding is greater than 8 hours.

[0060] In the step (1) of the present application, grind until the color distribution is uniform and the radiation shielding filler slurry can be well dispersed when stirred in the step (2), that is, the grinding is completed.

[0061] The third aspect of the present invention provides an applicatio...

Abstract

The invention relates to the technical field of radiation protection, and particularly relates to a radiation protection composite material as well as a preparation method and application thereof. Theradiation protection composite material is prepared from, by weight, radiation shielding filler slurry and liquid rubber, wherein the radiation shielding filler slurry is prepared from the followingcomponents in parts by weight: 100-150 parts of bismuth trioxide, 1-10 parts of filler and 1-10 parts of polyacrylate. The radiation protection composite material provided by the invention is lead-free and non-toxic and has excellent flexibility and ductility, the high-concentration radiation shielding filler is uniformly dispersed in the liquid rubber and has efficient anti-radiation performance,and the prepared radiation protection gloves meet ASTMD3578-01 edition of Latex Inspection Glove Standard Specification, the requirements of YY / T0481-2016 Medical Industry Standard of People's Republic, and the GBZ 130-2020 edition of Standard for Occupational Health of the People's Republic of China, injuries caused by X-rays can be effectively prevented, fine surgical operations in clinical interventional surgeries can be met, and harm to hands of operators can be reduced.

Description

technical field [0001] The invention relates to the technical field of radiation protection, and more specifically, the invention relates to a radiation protection composite material, a preparation method and an application thereof. Background technique [0002] The application of various radioactive rays in national defense, military affairs, medicine, scientific and technological research, nuclear industry and atomic energy technology continues to deepen and develop. Occupational exposure in the practice of interventional radiology and nuclear medicine, while using radiation to obtain all kinds of information people need, long-term exposure to radiation or passive acceptance of radiation will cause damage to the human body. Especially in clinical interventional therapy and medical diagnosis and treatment, fine hand manipulation is required. According to the National Health Commission of the People's Republic of China issued on April 3, 2020, and in the GBZ130-2020 "Radiol...
