Title (EN) POLYMERIC COMPOSITIONS
(FR) COMPOSITIONS POLYMERES
Abstract:
(EN) There is disclosed a method of producing a porous composite comprising the steps of: forming a shaped mass of particulate material whose surfaces have been pre-wetted with a liquid polymer which will not readily polymerise by the action of air or water vapour; and treating the particle/polymer mix with a liquid curing agent medium to initiate polymerization of the liquid polymer, either immediately before or after formation of the mass. The method may be practised with rubber crumb to form a horizontal layer defining a sports or play surface.
(FR) Procédé de fabrication d'un composite poreux, comportant les étapes suivantes: création d'une masse de matériau particulaire ayant une forme spécifique et dont les surfaces ont été mouillées à l'aide d'un polymère liquide ne se prêtant pas facilement à la polymérisation après exposition à l'air ou à la vapeur d'eau; et traitement du mélange de particules/polymère à l'aide d'un agent de polymérisation pour déclencher la polymérisation du polymère liquide, soit immédiatement avant soit après formation de la masse. Le procédé peut être mis en ÷uvre avec des miettes de caoutchouc pour constituer une couche horizontale destinée à servir de surface d'activités sportives ou de jeu.
