Abstract

The invention discloses a new material and a preparation method thereof. The new material is prepared from the following raw materials in parts by weight: 90 to 120 parts of polymethyl methacrylate, 30 to 50 parts of an acrylonitrile-styrene-acrylate copolymer, 40 to 60 parts of an ethylene-tetrafluoroethylene copolymer, 60 to 80 parts of glycerin, 3 to 5 parts of 5-norbornene-2-formamide, 1 to 2 parts of 4-hydroxy-3-methoxyphenyl acetic acid, 3 to 5 parts of rare earth oxide or rare earth ore, 3 to 5 parts of metal oxide, 3 to 5 parts of a coupling agent and 3 to 5 parts of a thermal stabilizer. The new material is soft and foldable, can be worn for a long time, is high in radiation performance, has a lead equivalent of 0.03 to 0.08 mm Pb / mm, and is applicable to a working or living environment with a medium-strength radiation source.

Description

technical field [0001] The invention belongs to the technical field of material development, and in particular relates to a radiation-proof material and a preparation method thereof. Background technique [0002] Radiation protection materials are more and more widely used in the process of scientific research, life or production. Radiation is a special hazardous substance that will cause physical harm to those exposed to it. Radiation injury has become a prominent pollution and hazard at present. Especially the radiation from household appliances, such as people who operate computers for a long time, microwave ovens, TVs, etc. at home. Especially the radiation to pregnant women has affected the health of the next generation. UVA rays and UVB rays are two types of rays that damage the skin contained in ultraviolet rays, and UVB is the main component that causes skin sunburn. UVB rays can penetrate the epidermis, making the skin rough, producing wrinkles and stains; X-ray ...
