Abstract

Cette invention concerne des matériaux de protection contre les rayonnements ainsi que des procédés de production de ces matériaux. Le matériau stratifié de protection contre les rayonnements de cette invention comprend au moins une couche de matière textile dont les deux côtés comprennent des couches identiques d'un matériau élastique renforcé par un mélange à base de métal polydispersé. La première couche comprend une charge dont la taille des particules est comprise entre 1,0 et 9,0 νm et la deuxième couche contient une charge dont la taille des particules est comprise entre 9,0 et 100 νm. Le procédé de production de ce matériau stratifié de protection contre les rayonnements consiste à appliquer plusieurs couches de matériau élastique renforcé par un mélange à base de métal polydispersé sur la couche de matière textile et à faire durcir chacune des couches. Chaque couche est appliquée sur les deux côtés de la matière textile simultanément en trempant cette dernière dans un matériau élastique renforcé pseudo-liquéfié. La première couche est appliquée en une quantité comprise entre 8 et 12 % de la masse de matière textile, le rapport de la seconde couche sur la première couche étant égal à 1:3. Le durcissement de chacune des couches est effectué à une température passant par paliers de 70 °C à 90 °C. Ce matériau stratifié de protection contre les rayonnements présente de hautes caractéristiques de performances ainsi qu'un large champ d'application.
