Problems solved by technology

[0007] The patent with the application number CN2016214363645 discloses a radiation protection glove for isotope production. The glove is made of tungsten-based rubber material. The preparation method of the glove is described, and the protective effect of the glove against gamma rays is not indicated
[0008] The patent with the application number CN2019106044720 discloses a disposable PVC anti-radiation plastic glove. The filling amount of the anti-radiation material of the glove is 20-35 parts, which is too small to meet the protection requirements for high-energy gamma rays.
[0009] The patent application number CN2008101885774 discloses a production method of radiation protection gloves. The gloves are made by latex dipping process. The radiation protection material used contains lead, which is easy to cause environmental pollution and human injury; in addition, in order to ensure that the filler does not settle in the emulsion, More excipients are added, which makes it difficult to remove the air bubbles in the emulsion, and it is difficult to guarantee the yield of the product

Abstract

The invention discloses a pair of lead-free nuclear radiation protective gloves and a preparation method thereof, solves the problems that lead-containing gloves pollute the environment and are harmful to the health of personnel, and belongs to the technical field of nuclear protective materials. The lead-free nuclear radiation protective glove is prepared from the following raw materials in parts by weight: 100 parts of rubber-based material and 200-700 parts of shielding functional filler. The preparation method comprises the following steps: weighing the rubber base material according to the formula ratio, and plastifying the rubber base material adding the rest raw materials, and mixing, calendering and tabletting the mixture to make a rubber sheet; and putting the rubber sheet into a forming mold for vulcanization to obtain the lead-free nuclear radiation protective glove. The lead-free nuclear radiation protection glove is high in shielding filler, can achieve protection of single or comprehensive radiation types of X-ray radiation, gamma-ray radiation and neutron ray radiation, and has good weather resistance and mechanical properties. According to the method disclosed by the invention, the shielding filler can be uniformly dispersed in the rubber-based material, so that the production cost can be effectively reduced, and the yield of products is improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear protection materials, and in particular relates to a lead-free nuclear radiation protection glove and a preparation method thereof. Background technique [0002] With the development of nuclear energy and nuclear technology, high-energy X-rays, gamma-rays and neutron-ray radiation are flooding industries such as nuclear fuel element material processing, nuclear waste treatment, nuclear radiation medicine production, and testing industries, which have serious consequences for the health of workers. a potential threat. Latex gloves containing lead or lead compounds are mainly used in the traditional hand radiation protection products of the staff, but the lead is easy to migrate out of the material, causing harm to people and the environment. [0003] The common manufacturing process of radiation protection gloves is divided into rubber molding process and latex dipping process. The latex dipping ...
