Title (EN) METHOD FOR THE PREPARATION OF BODIES FROM A CHARGE RESIN AND PRODUCT OBTAINED THEREBY
(FR) PROCEDE DE PREPARATION DE CORPS A PARTIR D"UNE LESINE CHARGEE ET PRODUIT OBTENU PAR LE PROCEDE
Abstract: front page image
(EN)The preparation of a body of charged resin is achieved by starting from a self-carrying cast piece with open pores which may be obtained in a known manner. A reaction mass is introduced into the pores of the piece. The pores of the piece are sealed before complete hardening. This may be achieved by means of a UV beam source. Before sealing, the pieces may be dipped temporarily into a glycol/glycerin bath without any danger of flowing of the reaction mass. A particularly interesting composite body is obtained from sand as charge material, of phenolformaldehyde and isocyanate resin as binders and a non-saturated polyester resin as reaction mass.
(FR)Pour la preparation d"un corps en resine chargee, on part d"une piece moulee autoportante a pores ouverts, qui peut etre obtenue de facon connue. On introduit dans les pores de la piece une masse de reaction. On scelle les pores de la piece avant le durcissement total. Ceci peut etre effectue au moyen d"une source de rayons UV. Avant le scellage, on peut mettre les pieces, de facon passagere, dans un bain glycol/glycerine, sans qu"il y ait danger d"ecoulement de la masse de reaction. On obtient un corps compose particulierement interessant a partir de sable comme charge, de resine phenolformoldehyde et de resine isocyanate comme liants et une resine polyester non-saturee comme masse de reaction.
