Abstract

The invention discloses a polypropylene shielding material which is composed of, by weight, 3-4 parts diphenyl silanediol, 120-140 parts of high-density polyethylene, 1-2 parts of ethylene bisstearamide, 1-3 parts of zinc powder, 0.8-1 part of azodicarbonamide, 1-2 parts of sucrose acetate isobutyrate, 3-5 parts of polyamide wax micropowder, 1-2 parts of ethoxylated ammonium alkylphenol sulfate, 0.1-0.2 parts of a photo-stabilizer 622, 0.7-1 part of dibasic lead phosphite, 2-3 parts of triethylamine, 1-2 parts of epoxy chloropropane and 10-14 parts of bentonite. By adding the zinc powder, thephoto-stabilizer 622 and the like, ultraviolet light can be effectively absorbed. The material also has certain shielding effects on other irradiation.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a polypropylene shielding material. Background technique [0002] With the continuous development of modern society, various high-energy rays are more and more widely used in military affairs, communications, medicine, industry, agriculture and people's daily life, which directly leads to the annual collective effective dose of radiation dose in the world. All kinds of rays have also brought a lot of harm to people to some extent, and have been considered as the fourth largest public hazard after air pollution, water pollution and noise pollution; [0003] With the advancement of science and technology, in order to reduce the negative effects of various types of radiation pollution on people, it is necessary to develop shielding materials with certain protective functions to resist various rays and microwaves; [0004] Polypropylene material is a semi-crystalline thermoplastic. It has ...
