A rigid and flexible protective mortar for nuclear power plants

Abstract

The invention discloses rigid-flexible protecting mortar for nuclear power plants and a preparation method of the rigid-flexible protecting mortar and belongs to the technical field of anti-radiation mortar. The rigid-flexible protecting mortar is prepared from the following components in parts by weight: 5-15 parts of cement, 6-10 parts of mineral powder, 30-50 parts of river sand, 3-5 parts of dispersed latex powder, 6-10 parts of wood fiber powder, 8-12 parts of nano-lead particles and 4-8 parts of epoxy resin powder. The invention aims at providing the rigid-flexible protecting mortar for the nuclear power plants and the preparation method of the rigid-flexible protecting mortar. The rigid-flexible protecting mortar has the characteristics of being long in service life, good in rigid-flexible property, high-temperature structure stability, and anti-radiation property, corrosion-resistant, wear-resistant and capable of avoiding layering, segregation and sagging and preventing nuclear leakage, thereby improving the security level of the nuclear power plants.

Description

technical field

[0001] The invention belongs to the technical field of anti-radiation mortar, in particular to a rigid-flexible protective mortar used in nuclear power plants. Background technique

[0002] Nuclear power is a clean, efficient and relatively safe energy source. A nuclear leakage accident in a nuclear power plant refers to the leakage of radioactive substances in the nuclear reactor, causing environmental pollution and exposing the public to radiation hazards. Therefore, it is necessary to have a little knowledge of how to deal with nuclear leaks to prevent accidents. The general impact of nuclear leakage on personnel is manifested in nuclear radiation, also called radioactive substances. The energy emitted by radioactive substances in the form of waves or particles is called nuclear radiation. Nuclear explosions and nuclear accidents have nuclear radiation. It has three radiation forms a, b and y. A radiation can be blocked with a piece of paper, but inhala...
