  • the transfer mirror surface coating method according to the present invention has a great advantage in that the peel strength, heat resistance, and flame resistance of a stamp film, paper pasting, etc. by using UV glue are greatly improved. It is possible to carry out complete integrated polymerization by EB irradiation up to the UV-cured part in a lump, which results in a polymerized resin in which each layer is chemically integrated. Furthermore, due to radical polymerization by ⁇ ⁇ ⁇ , the bonding force between the molecules becomes very strong, and it becomes strong against shrinkage due to heat, and there is no mixing of oxygen, which causes combustion, in the cured resin. There is a significant improvement.
  • the transfer mirror surface coating method according to the present invention can form a resin layer that satisfies all of the properties of design, stain resistance, chemical resistance, heat resistance, flame resistance, scratch resistance, and mirror surface. According to the present invention, it is possible to provide a high-quality transfer mirror surface coating material that can be used not only for architectural interior materials satisfying the above-mentioned characteristics but also for furniture materials having excellent designability and mirror finish at a low cost. Since a thick film can be transferred and coated on metal, an exterior material having extremely high weather resistance and flame resistance can be provided.

Abstract

L'invention concerne un matériau de revêtement par transfert ou de matériau de revêtement de miroir par transfert, utilisable pour des matériaux intérieurs et extérieurs pour la construction, des matériaux pour meubles et similaires, produits en masse par le procédé de transfert. Elle porte également sur un procédé d'application dudit matériau. On utilise un nouvel adhésif obtenu par l'addition d'un monomère ou oligomère à faible viscosité d'une résine de polymérisation radicalaire à une colle EB, de sorte que la viscosité de la colle soit réduite, et par l'addition d'un agent de photopolymérisation à cette dernière, en quantité empêchant la résine de durcir complètement sous rayonnement UV. L'adhésif est semi-durci et un film estampé produit à l'aide d'une presse à estamper à chaud est lié à celui-ci. Ainsi, on obtient un lissé accru après le transfert ou l'application de papier ou de film à ce dernier. Par ailleurs, le durcissement et le liaisonnement peuvent s'effectuer par irradiation EB. Etant donné que la vitesse de transfert et la vitesse d'application du papier ou du film dépendent de la vitesse de durcissement par irradation EB, le transfert et le liaisonnement peuvent s'effectuer à une vitesse de 30m/min ou plus. Le matériau d'enduction par transfert ou d'enduction de miroir par transfert présente d'excellentes propriétés, comme par exemple, un aspect, une résistance à la souillure, aux produits chimiques, à la chaleur, au feu, au rayage excellents et constitue une excellent fini de miroir pour tous les matériaux intérieurs de construction.
