Abstract
Poudre céramique enrobée comprenant plusieurs particules céramiques et un polymère d'enrobage siloxane avec greffage en forme d'étoile et enrobant au moins une partie des particules. Le polymère d'enrobage comprend Si (w, x, y, z), w, x, y et z étant respectivement des unités monomères tétrafonctionnelles, trifonctionnelles, bifonctionnelles et monofonctionnelles à pourcentage molaire, w étant d'environ 20 à 100, x d'environ 0 à 30, y d'environ 0 à 50 et z d'environ 0 à 10, et au moins une unité parmi w, x, y et z étant supérieure à zéro. Le procédé de fabrication d'une poudre céramique enrobée comprend les stades suivants: (a) polymérisation d'un monomère tétrafonctionnel du siloxane et d'au moins un monomère trifonctionnel, bifonctionnel et monofonctionnel du siloxane, (b) ajout d'une certaine quantité de poudre céramique dans la cuve à réaction, (c) mélangeage cisaillé de la poudre céramique pendant un laps de temps suffisant pour humecter de façon substantielle toute la surface de la poudre, (d) ajout du polymère du siloxane préparé au stade (a) dans la cuve à réaction contenant de la poudre mélangée avec cisaillement, (e) mélangeage cisaillé de la poudre céramique mélangée avec cisaillement et du polymère du siloxane pendant un laps de temps suffisant pour former une poudre céramique enrobée de polymère de siloxane et (f) séparation de la poudre céramique enrobée des composants résiduels dans la cuve à réaction.
