Abstract
Description
La présente invention a trait au domaine des revêtements de terrains en vue de la realisation de sols souples et poreux aptes a être utilisés comme aires de jeux ou de sports, comme par exemple des terrains de tennis. Elle concerne tout particulierement de nouvelles compositions, destinées à être appliquées sur des chapes rigides et dures constituant l'assise de fondation d'un terrain de sport, et fournissant des enduits souples et poreux permettant notamment l'évacuation des eaux pluviales. The present invention relates to the field of floor coverings for the realization of soft and porous floors suitable for use as play areas or sports, such as tennis courts. It particularly concerns new compositions, intended to be applied on rigid and hard screeds constituting the foundation of a sports field, and providing flexible and porous coatings allowing in particular the evacuation of rainwater.
De nombreux terrains de sports, en particulier des terrains de tennis, comportent comme chape rigide des dalles ou plaques en béton poreux (appelé aussi caverneux) ou encore des enrobés poreux, de constitution bien connue. La porosité est destinée à faciliter l'évacuation, par l'assise, des eaux pluviales et/ou de nettoyage. Many sports fields, especially tennis courts, have as rigid screed porous concrete slabs or plates (also called cavernous) or porous mixes, well known constitution. The porosity is intended to facilitate the evacuation, by the seat, rainwater and / or cleaning.
Habituellement, cette chape est recouverte, à titre d'enduit superficiel, par une peinture aqueuse pigmentée renfermant des polymères ou interpolymeres comme liants. Une telle couche finale ne confère pas la souplesse nécessaire au sol et elle. presente aussi divers inconvenients parmi lesquels il faut mentionner notamment : une usure relativement rapide, qui nécessite d'assez fréquents rajeunissements des surfaces de ce type, mais surtout un pouvoir glissant qui devient dangereux en cas de forte humidité du fait de l'imperméabilitê de tels enduits et de leur teneur, faible ou nulle, en charges sableuses. Usually, this screed is coated, as a surface coating, with a pigmented aqueous paint containing polymers or interpolymers as binders. Such a final layer does not provide the necessary flexibility to the soil and it. also presents various disadvantages among which we must mention in particular: a relatively rapid wear, which requires frequent rejuvenation of surfaces of this type, but especially a sliding power that becomes dangerous in case of high humidity due to the impermeability of such coatings and their content, low or zero, in sandy charges.
L'invention a pour but d'obvier à ces inconvenients et de mettre au point un type de revêtement qui, tout en apportant la souplesse nécessaire au béton ou à l'enrobé de base, confere un caractere antidérapant a la surface et inhibe les phénomènes de glissement sur cette derniere. Elle vise en outre une composition superficielle ayant de bonnes caractéristiques de porosité et apte d'une part a permettre une évacuation partielle des eaux au travers de sa couche mais aussi à évacuer une autre partie de ces eaux par simple ruissellement, en évitant ainsi une détérioration prématurée des fondations de l'ouvrage. The object of the invention is to obviate these drawbacks and to develop a type of coating which, while providing the necessary flexibility to the concrete or the base mix, imparts a non-slip character to the surface and inhibits the phenomena slip on the latter. It also aims a surface composition having good porosity characteristics and able on the one hand to allow a partial evacuation of water through its layer but also to evacuate another part of these waters by simple runoff, thereby avoiding deterioration premature foundation of the book.
Pour atteindre ces buts, l'invention propose de substituer à la peinture superficielle susvisée un revêtement poreux constitué par la combinaison d'une poudre et/ou pâte pigmentaire et d'une dispersion aqueuse à base de certains terpolymères et de charges à proportions relatives bien déterminées par rapport au liant polymère, d'autres additifs conventionnels étant incorporés à cette dispersion pour obtenir les résultats visés. To achieve these aims, the invention proposes to replace the above surface paint with a porous coating consisting of the combination of a powder and / or pigment paste and an aqueous dispersion based on certain terpolymers and charges in relative proportions well determined with respect to the polymeric binder, other conventional additives being incorporated in this dispersion to achieve the desired results.
Conformément à l'invention, la dispersion aqueuse comprend avantageusement, pour 100 parties en poids
a) 20 à 40 parties d'un terpolymère d'éthylène, chlorure de vinyle et acétate de vinyle ;
b) 30 a 120 parties d'une charge fine dont la majeure partie des particules a un diamètre inférieur à 0,6 mm ;
c) 0,5 à 1,5 partie d'un agent thixotrope insensible a l'eau f
d) 0,2 a 0,8 partie d'un agent dispersant des matériaux de coloration, de type anionique ou non ionique ;
e) 0,1 à 0,3 partie d'un agent anti-mousse exempt de silicone ;
f) 0,3 à 1,1 partie d'un agent biocide ; le complément à 100 parties étant constitué par de l'eau ordinaire, comme par exemple de l'eau de ville.According to the invention, the aqueous dispersion advantageously comprises, per 100 parts by weight
a) 20 to 40 parts of a terpolymer of ethylene, vinyl chloride and vinyl acetate;
b) 30 to 120 parts of a fine filler, most of the particles of which have a diameter less than 0.6 mm;
c) 0.5 to 1.5 parts of a thixotropic agent insensitive to water f
d) 0.2 to 0.8 parts of an anionic or nonionic coloring agent dispersant;
e) 0.1 to 0.3 parts of a silicone-free antifoam agent;
f) 0.3 to 1.1 parts of a biocidal agent; the complement to 100 parts consisting of ordinary water, such as city water.
Selon une caractéristique de l'invention, pour obtenir la porosité désirée du revêtement final, la quantité de charge dans la composition doit atteindre au moins 170 parties pour 100 parties (poids) du liant terpolymêre et elle est avantageusement comprise entre 170 et 300 parties (poids). Cette charge est constituée de préférence par un sable siliceux de fourchettes granulometriques 70-420 microns ou 74-590 microns. Ceci pour la couche superficielle mais on peut mettre en oeuvre, pour la couche de fond, des granulés concasses, par exemple type silex, ou encore du carbonate de calcium, de calibre 0,5 a 3 mm. En outre, dans certains cas, on peut ajouter a la charge, de la silice de diato hées de granulometrie préférentielle 1 à 10 microns de façon a augmenter la resistance à l'abrasion.Toutefois, cet ajout ne doit pas être utilisé en doses excessives afin de ne pas diminuer la porosité recherchee. According to a characteristic of the invention, to obtain the desired porosity of the final coating, the amount of filler in the composition must reach at least 170 parts per 100 parts (weight) of the terpolymer binder and it is advantageously between 170 and 300 parts ( weight). This filler preferably consists of silica sand with 70-420 micron or 74-590 micron granulometric forks. This for the surface layer but can be used for the primer, crushed granules, for example flint type, or calcium carbonate, size 0.5 to 3 mm. In addition, in certain cases, it is possible to add, to the filler, diatomaceous silica of preferential granulometry 1 to 10 microns so as to increase the resistance to abrasion. However, this addition should not be used in excessive doses. in order not to diminish the sought porosity.
Tout interpolymère de chlorure de vinyle, acétate de vinyle et éthylène peut convenir selon l'invention. En pratique les pourcentages de monomères varient généralement entre 5 et 30 % pour l'éthylène, 30 à 90 % pour le chlorure de vinyle et 5 % 40 X pour 1 'acétate de vinyle (pourcentages en poids). Any interpolymer of vinyl chloride, vinyl acetate and ethylene may be suitable according to the invention. In practice, the percentages of monomers generally vary between 5 and 30% for ethylene, 30 to 90% for vinyl chloride and 5% for vinyl acetate (percentages by weight).
Les autres constituants précités de la composition sont des adjuvants dont l'action est connue en soi. Par exemple, on peut utiliser comme agent thixotrope de l-a silice colloïdale de granulometrie 1 à 10 microns environ ou tout autre matériau de fonction équivalente a l'excep- tion, toutefois, des produits sensibles à l'eau comme par exemple les dérivés et polymères cellulosiques. L'agent dispersant peut etre choisi parmi les produits anioniques ou non ioniques déjà mis en oeuvre dans les dispersions aqueuses de polymeres, comme par exemple des éthers aliphatiques de polyoxyalcoylenes ou alcoylarylés comme le houy)phénol éthoxylé. L'agent anti-mousse peut être constitué par un phosphate d'alcoyle ou produit équivalent.Enfin on peut utiliser comme biocide l'un quelconque ou des mélanges des produits bien connus, efficaces contre les algues et moisissures, tels que par exemple des complexes miscibles à l'eau a base de dérivés d'organo-étains ou produits d'action équivalente. The other aforementioned constituents of the composition are adjuvants whose action is known per se. For example, colloidal silica of about 1 to about 10 microns or any other equivalent functional material can be used as the thixotropic agent with the exception, however, of water-sensitive products such as derivatives and polymers. cellulose. The dispersing agent may be chosen from anionic or nonionic products already used in aqueous polymer dispersions, for example aliphatic ethers of polyoxyalkyl or alkylaryl ethers such as ethoxylated houy) phenol. The antifoaming agent may consist of an alkyl phosphate or equivalent product. Finally, any one or mixtures of the well-known products effective against algae and molds, such as, for example, miscible with water based on organotin derivatives or products of equivalent action.
En outre, il s' avère souvent avantageux d'incorporer à la composition aqueuse précitée un solvant organique non miscible à l'eau, tel que white spirit ou autre, jouant le rôle d'agent coalescent et permettant de travailler à des températures voisines de zéro degré. In addition, it is often advantageous to incorporate in the aforementioned aqueous composition a water-immiscible organic solvent, such as white spirit or the like, acting as a coalescing agent and making it possible to work at temperatures close to 50.degree. zero degrees.
Comme composants pigmentaires incorporés a la dispersion aqueuse, on peut utiliser, a raison d'environ 2 à 10 % par rapport au poids de ladite dispersion, soit des poudres d'oxydes métalliques soit encore des préparations pigmentaires pâteuses a base de telles poudres et de colorants organiques soit encore des mélanges de poudre et de pète. As the pigment components incorporated in the aqueous dispersion, it is possible to use, at a rate of approximately 2 to 10% relative to the weight of said dispersion, either metal oxide powders or else pasty pigmentary preparations based on such powders and organic dyes is still mixtures of powder and fart.
