A kind of anti-radiation liquid organic glass

Abstract

The invention provides a radiation-proof liquid organic glass. Lead methacrylate and samarium methacrylate are used as radiation-proof components to prepare liquid radiation-proof organic glass. First, lead methacrylate is dissolved in cyclohexanone, and formazan Dissolve samarium acrylate in octanoic acid and propylene glycol, then weigh methyl methacrylate, dioctyl phthalate, cyclohexane, and n-butanol, put the above raw materials into the reaction kettle, stir, and heat to 78°C. Add the cyclohexanone solution of dibenzoyl peroxide dropwise and keep the temperature constant for 1-4 hours to obtain liquid organic glass. The plexiglass has the characteristics of excellent radiation protection performance and convenient secondary processing.

Description

technical field [0001] The invention belongs to the field of special organic glass and relates to a radiation-proof liquid organic glass. Background technique [0002] With the continuous development of national defense scientific research, radiation medicine and nuclear technology applications, various radioactive rays are widely used, and the harm of rays to the human body and the damage to the environment are gradually recognized by human beings. The research on various anti-radiation materials to protect these rays has become a very important and urgent topic. Traditional radiation protection materials generally use concrete, cement, lead plates, iron plates, etc. With the application of radiation in more and more fields, these materials have been difficult to meet the needs of various protective equipment production. In recent years, polymer based As a radiation protection material, composite materials have become a research hotspot. It is made of organic polymer mater...

Problems solved by technology

Traditional radiation protection materials generally use concrete, cement, lead plates, iron plates, etc. With the application of radiation in more and more fields, these materials have been difficult to meet the needs of various protective equipment production. In recent years, polymer based As a radiation protection material, composite materials have become a research hotspot. It is made of organic polymer materials as the matrix skeleton material and micro-powder with the function of absorbing rays as the filler. Among them, plexiglass (polymethyl methacrylate) is often used as the matrix material. At present, organic lead glass, organic barium glass, organic cadmium glass and other varieties have appeared, and related products and patents have also been reported

[0003] Lead or lead compounds are the mainstream of application as fillers, but they have two disadvantages: on the one hand, lead radiation-proof materials have good particle absorption ability for rays with energy higher than 88keV and between 13 and 40keV, but for energy Rays between 40 and 88keV have a region with very weak particle absorption ability (that is, "Pb weak absorption region"); on the other hand, lead is toxic and pollutes the environment, so its use is often restricted
