Abstract

The invention relates to a method enabling, in a single operation, a plane surface, even porous or uneven, to be coated with a film of resin or of lacquer having a glossy final state without any defects. The operation consists in pouring over the plate 1 to be coated, previously inclined and surrounded by a sealing member 3, a predetermined quantity of the selected substance 4, for example an epoxy resin, and in progressively pressing, with the aid of a polished plate 6 such that the resin spreads out over the entire surface, removing the air in front of it via the vent 8. After demoulding, the surface of the resin 4, spread out and cured, has the same polish (gloss) as the surface of the plate 6 serving to press it. There is thus obtained, in a single operation, that which would have required several operations using conventional methods.

Description

La brillance des objets que nous utilisons dans la vie courante est souvent recherchée pour son aspect m ais aussi parce qu'elle apporte l'assurance d'une bonne protection du matériau qu'elle recouvre. The brilliance of the objects we use in everyday life is often sought after for its mais aspect also because it provides the assurance of good protection of the material it covers.

En effet la brillance pourait se définir par une absence de porosité et c'et cette dernière qui favorise la dégradation de la matière en laissant pénétrer l'air et l'humidité. Indeed the shine could be defined by an absence of porosity and it is the latter which promotes the degradation of the material by letting the air and humidity penetrate.

La solution à laquelle on recours habituellement pour supprimer ou limiter ce défaut consiste à recouvrir la matière à protéger d'un film de résine ou de vernis. The solution usually used to eliminate or limit this defect is to cover the material to be protected with a film of resin or varnish.

L'application de ces produits se fait selon le cas,au pinceau, au tampon, au pistolet, au trempé, électrostatiquement, par coulage, avec machine à rideau, etc. The application of these products is carried out, as the case may be, with a brush, a pad, a spray gun, a dip, electrostatically, by casting, with a curtain machine, etc.

Lorsqu'on recherche un état final de surface parfait tous ces procédés ont pour point commun de nécessiter une ou plusieurs opérations supplémentaires en particulier le polissage et le ponçage.When looking for a perfect final surface condition all these processes have in common the need for one or more additional operations, in particular polishing and sanding.

DE plus les quelques microns d'épaisseur de vernis ou résine appliqués à chaque fois avec ces moyens ( sauf cependant pour la coulée ) obligent à utiliser souvent plusieurs couches successives. In addition, the few microns of varnish or resin thickness applied each time with these means (except, however, for casting) means that several successive layers are often used.

Au contraire avec le procédé préconisé ici une seule opération suffit pour obtenir une surface parfaite quelle que soit la porosité du support. On the contrary, with the process recommended here, a single operation is sufficient to obtain a perfect surface whatever the porosity of the support.

Le dessin annexé est une vue en coupe de l'appareil simplifié permettant le glaçage. The accompanying drawing is a sectional view of the simplified apparatus for glazing.

Tel qu'il est représenté,en figure l,le plateau ou la plaque 1 à glacer est placd en position inclinée sur le plateau 2 d'une presse. Il est entouré d'un bourrelet 3 de caoutchouc dépassant le bord supérieur du plateau 1 afin de ménager une cavité 4 dans la partie basse où sera versé une quantité déter; minée de résine ou de vernis préalablement ddbullés
La feuille 5 reposant sur le bord du bourrelet 3 est destinée à " estamper n son aspect de surface glacé à la résine en 4 une fois celle là étalée et durcie. Elle est constituée d'une matière de synthèse ne réagissant pas chimiquement au contact de la résine ou des solvants du vernis. Sont utilisables aussi la totale d'acier inoxydable, les stratifiés, etc.As shown, in FIG. 1, the plate or plate 1 to be glazed is placed in an inclined position on the plate 2 of a press. It is surrounded by a bead 3 of rubber protruding from the upper edge of the plate 1 in order to provide a cavity 4 in the lower part where a quantity of deter will be poured; mined with resin or varnish previously sprayed
The sheet 5 resting on the edge of the bead 3 is intended to "stamp n its glazed surface appearance with resin in 4 once it has spread and hardened. It is made of a synthetic material which does not react chemically on contact with resin or varnish solvents. Stainless steel total, laminates, etc. can also be used.

L'épaisseur doit être telle que la feuille 5 soit assez rigide pour ne pas trop fléchir sous l'effet de son poids au centre du plateau et cependant assez souple pour permettre un dé moulage en ligne après le durcissement de la résine. The thickness must be such that the sheet 5 is rigid enough not to bend too much under the effect of its weight in the center of the plate and yet flexible enough to allow in-line molding after the resin has hardened.

Sous la pression du plateau 6 de la presse déjà mentionnée la résine placée en 4 s'étale progressivement sur toute la surface de la plaque 1 à glacer. Simultannénient le bourrelet 3 de caoutchouc se comprime en assurant l'étanchéité.Under the pressure of the plate 6 of the press already mentioned, the resin placed in 4 spreads gradually over the entire surface of the plate 1 to be glazed. Simultaneously the bead 3 of rubber compresses while ensuring sealing.

Selon la forme de la plaque 1 il est parfois utile de faire appel, pour assurer une plus grande pression du bourrelet 3 sur le chant de la plaque 1, à une ceinture 7 de clinquant d'acier qui maintient la face extérieure du bourrelet 3. Dans d'autres cas la ceinture 7 est remplacée par un fer plat plus rigide qui peut strie droit ou mis en forme. Depending on the shape of the plate 1, it is sometimes useful to use, to ensure greater pressure of the bead 3 on the edge of the plate 1, a steel foil belt 7 which holds the outer face of the bead 3. In other cases the belt 7 is replaced by a more rigid flat iron which can streak straight or shaped.

Le bourrelet 3, dans sa partie la plus haute, est entamé d'une saignée transversale 8 permettant à l'air comprimé créé par la pression du plateau 6 de s'évacuer.  The bead 3, in its highest part, is started by a transverse groove 8 allowing the compressed air created by the pressure of the plate 6 to be evacuated.

Après durcissement de la résine ou du vernis l'étape rina- le consiste à enlever la feuille 5 intercalaire qui laisse sur la surface de la plaque 1 l'image de sa brillance. After the resin or varnish has hardened, the rinsing step consists in removing the interlayer sheet 5 which leaves the image of its gloss on the surface of the plate 1.

Les applications de ce procédé sont assez vaste5; elles vont du revêtement des planches utilisées en ébénisterie au glaçage des plateaux de tablent de guéridons.  The applications of this process are quite wide5; they range from the coating of the boards used in cabinetmaking to the glazing of the table tops of pedestal tables.
