Abstract

Process for manufacturing abrasion-resistant coatings based on thermosetting or thermoplastic synthetic resins, with inclusions concentrated at the surface, which can be used in buildings and industry for the chemical protection, the weatherproofing (sealing) and the finishing of surfaces, as well as for the manufacture of slabs, panels and other elements having plane surfaces. The novelty of the invention consists in using gravity or centrifugal force for obtaining a concentration of the hard particles 3 at the surface of the protective layer. <IMAGE>

Description

La présente invention concerne un procédé de renforcement des revêtements en résines synthétiques thermo-durcissables ou thermo-plastiques en les dotant d'une surface dure offrant une excellente résistance aux rayures et à l'usure partout où ces revêtements sont exposés à des frottements. The present invention relates to coatings reinforcing method of heat-curable or thermo-plastic synthetic resins by providing a hard surface with excellent scratch resistance and wear wherever these coatings are exposed to friction.

Les revêtements en résines synthétiques polyester, époxydes polyuréthane, polyméthacrylate de méthyle et autres, ont en commun avec la plupart des matières plastiques un défaut majeur pour de nombreuses applications, qui est une mauvaise résistance à l'abrasion. The coatings of polyester synthetic resins, polyurethane epoxy, polymethyl methacrylate and others, have in common with most plastics a major drawback for many applications, which is a poor resistance to abrasion.

De nombreuses tentatives pour remédier à ce défaut ont été faites, avec plus ou moins de succés, entre autre en incluant à la résine, destinée à former la couche de surface, des matières dures plus ou moins finement divisées, les résultats obtenus restant en général peu satisfaisants du fait que les matériaux d'inclusion se trouvent dispersés dans la masse ou même peuvent se concentrer sur la face interne de la couche de protection. Numerous attempts to remedy this defect have been made, with varying degrees of success, among others including the resin to form the surface layer, more or less finely divided hard materials, the results obtained remaining in general unsatisfactory because the inclusion materials are dispersed in the bulk or even can focus on the inside of the protective layer.

Le procédé de l'invention apporte à ce problème une solution efficace en permettant d'obtenir une concentration maximale de particules dures au niveau même de la surface du produit formant une véritable armure. The method of the invention brings to this problem in an effective solution to obtain a maximum concentration of hard particles at the same level of the product surface forming a true armor.

L'invention consiste à former à la -surface des divers matériaux à protéger une couche de quelques dixièmes à plusieurs millimètres d'une résine choisie pour ses qualités par rapport à l'application envisagée, par exemple: anti-acide, étanchéité, souplesse ou rigidité, résistance à la pression, au cisaillement, au poiçonnement et autres. The invention consists in forming the -surface of various materials to protect a layer of a few tenths to several millimeters of a resin selected for its features in relation to the envisaged application, for example antacid, sealing, flexibility or stiffness, compressive strength, shear strength, the punching shear and others.

Dans la résine choisie sont incorporées, par malaxage, le ou In the selected resin are incorporated, by mixing, or
les matériaux durs( 1), sélectionnés pour répondre aux besoins, hard materials (1), selected to meet the needs,
divisés selon des courbes granulométriques déterminées par l'état de surface requis. divided according to particle size distribution curves determined by the required surface finish.

Les matériaux durs utilisés peuvent être de différentes natures: minérales, métalliques. The hard materials used can be of different types: mineral, metal.

L'originalité de l'invention consiste à utiliser la gravité ou la force centrifuge pour obtenir une concentration, à la surface de la couche de protection, des particules dures(3) qui, par leur nature même sont plus denses que la résine. The originality of the invention consists in using gravity or centrifugal force to obtain a concentration at the surface of the protective layer, the hard particles (3) which, by their very nature are denser than the resin. La vitesse de réticulation de la résine employée étant réglée pour permettre une décantation The rate of crosslinking of the resin used is adjusted to allow for settling
(3)satisfaisante des particules en suspension. (3) satisfactory suspended particles.

La mise en oeuvre de Invention nécessite l'emploi de moules horizontaux plans à surface polie(2). Implementation of Invention requires the use of horizontal molds polished surface planes (2).

La résine chargée de particules dures est alors versée sur la surface de moulage en une couche d'épaisseur homogène selon les caractéristiques requises. The resin loaded with hard particles is then poured on the mold surface in a homogenous layer thickness according to the required characteristics. Les particules dures vont migrer vers la surface du moule par gravité(3) formant une surface lisse et résistante après réticulation du liant(5). The hard particles will migrate to the surface of the gravity mold (3) forming a smooth and resistant surface after crosslinking of the binder (5).

Dans le procédé de l'invention le revêtement décrit ci-dessus est applicable sur des objets plans, par exemple panneaux, tables, dalles, carreaux et autres. In the method of the invention, the coating described above is applicable on flat objects, for example panels, tables, blocks, tiles and the like. La fixation du revêtement sur l'objet à protéger peut être effectuée par encollage du revetement, laissé sur le moule(3), en utilisant un adhésif convenable, entre autres de la résine. Fixing the coating on the object to be protected may be effected by gluing of the coating left on the mold (3), using a suitable adhesive, including the resin. L'objet à protéger est ensuite appliqué sur la couche d'adhésif et maintenu sous une pression suffisante pendant le temps de prise de l'adhésif. The object to be protected is then applied to the adhesive layer and maintained under sufficient pressure during the curing time of the adhesive.

Dans le procédé de l'invention l'équipement mis en oeuvre peut également être utilisé pour la fabrication d'objets plans à surface dure: dalles, plaques, tables, carreaux et autres, en ajoutant à la couche de protection, décrite ci-dessus, après réticulation, au lieu d'un objet existant, une couche, plus ou moins épaisse selon la force désirée, d'un mortier de résine, consistant en un mélange de résine et de quartz ou autre charge adéquate, qui est ensuite réticulé. In the method of the invention, the equipment used may also be used for the manufacture of planar objects to hard surface: tiles, plates, tables, and other tiles, by adding to the protective layer described above after cross-linking, instead of an existing object, a layer thicker or thinner depending on the desired strength, a resin mortar, consisting of a mixture of resin and quartz or other suitable filler, which is then crosslinked.

Le procédé de l'invention peut également être utilisé pour la The method of the invention can also be used for the
fabrication de revêtements souples, en mettant en oeuvre des preparation of flexible coatings, employing
résines adéquates, destinés à la protection des sols dans les lieux à fort passage de piétons ou de mobiles à roues ainsi qu'à toutes autres applications où le revêtement doit être souple et présenter en même temps une bonne résistance à l'usure. adequate resins for the protection of soil in places with high traffic pedestrian or wheeled mobile and all other applications where the coating must be flexible and submit with good wear resistance. Ces mêmes revêtements peuvent également être formulée pour présenter~ une bonne résistance aux agressions chimiques et, de plus, être utilisés pour résoudre les problèmes d'étanchéité. These coatings can also be formulated to provide ~ a good chemical resistance and, in addition, be used to solve sealing problems.
