Abstract

The invention provides an epoxy resin based radiation protection material and specifically relates to a radiation protection material with rare earth oxide and lead oxide as anti-radiation filler and epoxy resin as the base material. The epoxy resin based radiation protection material comprises the following raw materials, in parts by mass: 100 parts of epoxy resin E-51, 50-100 parts of a polyamide curing agent, 10-60 parts of rare earth oxide, 10-60 parts of lead oxide, and 0.2-2 parts of a coupling agent. Under the combined effect of the rare earth oxide and the lead oxide, the radiation protection material has greater radiation protection capability and can be applied in radiation medicine.

Description

technical field [0001] The invention belongs to the field of radiation protection materials, and relates to an epoxy resin-based radiation protection material, in particular to a radiation protection material prepared with rare earth oxide and lead oxide as radiation protection fillers and epoxy resin as a base material. Background technique [0002] Various radioactive rays in radiological medicine have great harm to the human body. The application of radiation protection materials can eliminate or reduce the harm of rays. Traditional radiation protection materials generally use concrete, cement, lead plates, iron plates, etc. In recent years, polymer-based Composite materials as radiation protection materials have become a research hotspot. They are prepared with organic polymer materials as the matrix and skeleton materials and micro-powders with the function of absorbing rays as fillers. Among them, the commonly used fillers are lead or lead compounds. Lead radiation prot...
