MISE EN OEUVRE POUR L'HYDROFUGATION ET LA PROTECTION
DE SURFACES DIVERSES.WATER-REPELLENT COMPOSITIONS, PROCESS FOR THEIR PREPARATION AND THEIR
IMPLEMENTATION FOR HYDROFUGATION AND PROTECTION
OF VARIOUS SURFACES.
La présente invention a pour objet des compositions pour lthydrofugation et la protection de surfaces diverses telles que façades, tuiles etc...., leur procéde de préparation et leur mise én oeuvre pour le-traitement desdites surfaces. The subject of the present invention is compositions for hydrofugging and protecting various surfaces such as facades, tiles, etc., their preparation process and their implementation for the treatment of said surfaces.
Z1 est connu d'apres la demande de brevet allemand n 2.355.813, d'utiliser, comme liant pour la préparation de revêtements pigmentés d'extérieur ou d'intérieur présentant une résistance à l'eau améliorée, une dispersion aqueuse contenant
- un polymère d'acrylate de butyle, éthyle ou méthyle, ou un -copolymère å base d'acide acrylique et/ou méthacrylique ou de leurs esters ;
- et de 2 à 5 % de poids de la dispersion, d'un silicone en phase aqueuse, en particulier de méthylsiliconate de sodium.Z1 is known from German Patent Application No. 2,355,813 to use, as a binder for the preparation of exterior or interior pigmented coatings having improved water resistance, an aqueous dispersion containing
a polymer of butyl acrylate, ethyl or methyl, or a copolymer based on acrylic and / or methacrylic acid or their esters;
and from 2 to 5% by weight of the dispersion, of a silicone in the aqueous phase, in particular of sodium methylsiliconate.
I1 est également connu d'après le brevet américain n04.O12.355 de protéger contre l'érosion la surface de matières finement divi se-es, par traitement à l'aide d'une composition contenant :
une dispersion aqueuse de polymères filmogènes tels queles terpolymères styrène-butadiène - acide acrylique ou acrylate, les polyoLéfines, le polyacétate de vinyle, les polyacrylates ou polyméthacrylates d'alkyle..... It is also known from US Pat. No. 4,012,355 to protect the surface of finely divided materials against erosion by treatment with a composition containing:
an aqueous dispersion of film-forming polymers such as styrene-butadiene-acrylic acid or acrylate terpolymers, polyolefins, polyvinyl acetate, alkyl polyacrylates or polymethacrylates .....
et un silicone en solution aqueuse ou hydrocarbonée, en particulier un siliconate en solution aqueuse, avec un rapport pondéral polymère filmogène/silicone compris entre 12/1 et 1/1. and a silicone in aqueous or hydrocarbon solution, in particular a siliconate in aqueous solution, with a film-forming polymer / silicone weight ratio of between 12/1 and 1/1.
I1 est particulièrement interessant que des compositions à base de polymeres synthétiques utilisées pour le traitement de surfaces telles que des façades, tuiles....présentent, outre des propriétés d'hydrofugation, les caractéristiques suivantes
- une bonne filmogénéitê
- une bonne stabilité aux ultra-violets
- une bonne stabilité en milieu alcalin, c'est-à-dire être faiblement visqueuses et ne se saponifiant pas en milieu alcalin, en,articulier à pH supérieur à 10. It is of particular interest that compositions based on synthetic polymers used for the treatment of surfaces such as facades, tiles, etc. have, in addition to water repellency properties, the following characteristics:
- good filmogeneity
- good ultraviolet stability
- Good stability in alkaline medium, that is to say, be slightly viscous and not saponifying in an alkaline medium, articular at pH greater than 10.
I1 a été constaté que les polymères contenant des motifs carboxyliques dérivant d'acides mono- ou di-carboxyliques éthyléniques par exemple sont à exclure en raison de leur mauvaise stabilité en milieu alcalin. It has been found that polymers containing carboxylic units derived from ethylenic mono- or di-carboxylic acids for example are to be excluded because of their poor stability in an alkaline medium.
La demanderesse a trouvé que les copolymères du type styrèneacrylate d'alkyle en dispersion au sein d'un milieu aqueux stable à pH alcalin, présentent les caractéristiques ci-dessus recherchées et peuvent être associées à une quantité d'agent d'hydrofugation nettement supérieure à celle présente dans les compositions à base de copolymères d'acrylate d'alkyle de l'art antérieur. The Applicant has found that the copolymers of the alkyl styrene acrylate type dispersed in an aqueous medium that is stable at alkaline pH, have the characteristics desired above and can be associated with a quantity of water repellency agent substantially greater than that present in the compositions based on alkyl acrylate copolymers of the prior art.
La demanderesse a trouvé une composition stable au stockage, facilement applicable sur les façades- par les procédés conventionnels (rouleau, pistolet pneumatique...), qui après séchage forme un film présentant les caractéristiques d'adhérence et de tenue aux ultra-violets des résines acryliques, les propriétés de surface des résines silicones et permettant une hydrofugation améliorée des façades. The Applicant has found a stable storage composition, easily applicable on the facades- by conventional methods (roller, pneumatic gun ...), which after drying forms a film having the characteristics of adhesion and ultraviolet resistance of the Acrylic resins, the surface properties of silicone resins and allowing improved water repellency of the facades.
La composition faisant l'objet de l'invention contient une dispersion aqueuse d'un copolymère d'acrylate d'alkyle et un alkylsiliconate alcalin, ladite composition étant caractérisée en ce que
- la dispersion aqueuse est constituée d'un copolymère filmogène d'acrylate d'alkyle et d'un monomère vinylaromatique en dispersion au sein d'un milieu aqueux stable à pH basique, ledit monomère vinylaromatique étant tel que lthomopolymère correspondant audit monomère vinylaromatique présente un point de transition vitreuse compris entre 70 et 1700C
- la quantite d'alkylsiliconate alcalin présente est de 0,05 à 0,17 moles d'alkylsiliconate pour 100 g de copolymère sec, l-'entité élémentaire correspondant au terme "mole" étant le groupe ment
the aqueous dispersion consists of a film-forming copolymer of alkyl acrylate and of a vinylaromatic monomer dispersed in a stable pH-stable aqueous medium, said vinylaromatic monomer being such that the homopolymer corresponding to said vinylaromatic monomer exhibits a glass transition point between 70 and 1700C
the quantity of alkaline alkylsiliconate present is from 0.05 to 0.17 moles of alkylsiliconate per 100 g of dry copolymer, the elementary element corresponding to the term "mole" being the group
Comme exemple de monomère vinylaromatique on peut citer le styrene et lesméthylstyrenes. As an example of a vinylaromatic monomer, mention may be made of styrene and methylstyrenes.
Les acrylates d'alkyle pouvant être mis en oeuvre sont ceux dont lthomppolymère correspondant présente un point de transition vitreuse compris entre +100C et -60 C. The alkyl acrylates that can be used are those whose corresponding copolymer has a glass transition point of between + 100 ° C. and -60 ° C.
On peut citer les acrylates d'alkyle dont le groupe alkyle contient de 1 à 8 atomes de carbone et de préférence de 1 à 4 atomes de carbone. Alkyl acrylates in which the alkyl group contains from 1 to 8 carbon atoms and preferably from 1 to 4 carbon atoms may be mentioned.
Les quantités respectives de monomère vinylaromatique et d'acrylate d'alkyle à mettre en oeuvre sont choisies de telle manière que le copolymère obtenu présente un point de transition vitreuse compris entre -50C et +250C. The respective quantities of vinylaromatic monomer and of alkyl acrylate to be employed are chosen in such a way that the copolymer obtained has a glass transition point of between -50.degree. C. and + 250.degree.
Les quantités de monomères à utiliser sont fonction de la nature desdits comonomères et de la température de transition vitreuse du copolymère désirée. Lesdites quantités peuvent être facilement déterminées en appliquant par exemple la formule de FOX donnée dans Bull. An. Phys.Soc. 1956, 1, 123,
Ainsi : - un copolymère styrene-acrylate d'éthyle présente un
un point de transition vitreuse variant entre OOC et
200C lorsque le rapport styrene/acrylate d'éthyle
varie entre 26/74 et 45/55
- un copolymere styrene-acrylate de propyle présente
un point de transition vitreuse variant entre OOC
et 20"C lorsque le rapport styrene/acrylate de propyle
varie de 36/64 à 52/48 le polystyrene présentant un point de transition vitreuse de +1000C, le polyacrylate d'éthyle de -240C et le polyacrylate de propyle de -37 Cv
Les valeurs de points de transition vitreuse indiquées sont celles mesurées selon la méthode dite "Differential scanning calorimetry" décrite par exemple par A. Lambert dans "Polymer 10, 319, 1969".The amounts of monomers to be used are a function of the nature of said comonomers and the glass transition temperature of the desired copolymer. Said quantities can be easily determined by applying, for example, the FOX formula given in Bull. An. Phys. Sac. 1956, 1, 123,
Thus: a styrene-ethyl acrylate copolymer has a
a glass transition point varying between OOC and
200C when the ratio styrene / ethyl acrylate
varies between 26/74 and 45/55
a styrene-propyl acrylate copolymer exhibiting
a glass transition point varying between OOC
and 20 "C when the ratio styrene / propyl acrylate
varies from 36/64 to 52/48 polystyrene having a glass transition point of + 1000C, ethyl polyacrylate -240C and propyl polyacrylate -37 Cv
The values of glass transition points indicated are those measured according to the "Differential scanning calorimetry" method described for example by A. Lambert in "Polymer 10, 319, 1969".
Les dispersions aqueuses de copolymeres de monomère vinylaromatique et d'acrylate d'alkyle sont obtenues par polymérisation en émulsion aqueuse desdits monomères au sein d'un milieu stable à pH alcalin.
