Abstract

The invention relates to a light gypsum board capable of preventing neutron radiation, the gypsum board contains 19%-55% by mass of packaged porous solid waste, the packaged porous solid waste adsorbs a boric acid solution with the concentration of 0.2%-0.7%, and polymethyl methacrylate with the boron content of 0.5%-1% is used for packaging. The light gypsum board capable of preventing neutron radiation has good moderation and absorption effects on neutrons, is high in waste utilization rate, environmentally friendly, light in weight, capable of adjusting humidity and high in functionality, and various properties of the light gypsum board meet the requirements of GBT23451-2009 Lightweight Partition Board Standards for Building.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a neutron radiation-resistant lightweight gypsum board and a preparation method thereof. Background technique [0002] In the development and utilization of new energy so far, nuclear energy is the key area of ​​development in my country. The shielding protection of nuclear power plant equipment, medical equipment, and military equipment has begun to receive attention, especially after the Fukushima nuclear power plant leakage accident in Japan, people pay more attention to nuclear radiation. security issues. [0003] Neutron radiation occurs when a nucleus has stabilized by decreasing one mass unit, and can result from spontaneous or induced nuclear fission, fusion, or other nuclear reactions. Neutron radiation is composed of free neutrons. When interacting with matter, it mainly interacts with the nuclear force in the nucleus. When neutrons pass through m...
