PASTE MATERIAL FOR PROTECTION FROM NEUTRON RADIATION AND METHOD FOR PREPARING pasty material PROTECTION FROM RADIATION NEUTRON

摘要

1. The paste material for protection against neutron radiation, comprising a synthetic plastic mass and filler - powdered amorphous boron, characterized in that the synthetic plastic mass used grease VNIINP-293 with the following ratio of components, wt%: wherein the specific surface of the powder. amorphous boron is not less than 15 m / D.2. A method for preparing a paste material for protection against neutron radiation, comprising mixing in a paddle mixer plastic synthetic mass and filler - powdered boron amorphous, characterized in that the plastic synthetic weight used grease VNIINP-293 with respect to boron amorphous, wt.%: 91-97 / 3-9, is performed in the mixer for mixing highly viscous materials at a temperature of not more than 20 ° C for at least 1.5 h and a residual pressure in the mixing chamber is not more than 10 Pa to n radiation homogeneous mass, followed gomogenizatsiey.3. A method according to claim 2, characterized in that the mixing is carried out in a high mixer with Z-shaped blades.
