Definitions

  • the subject of the invention is a product for the preparation of a cement coating intended to cover the external face of a support such as a building wall and which can be used, in particular for the production of an insulation coating. from the outside.
  • the insulating wall usually consists of expanded polystyrene (PS E) or glass wool or rock wool panels and can be fixed to the support either by gluing, or by various devices of the staple type or pulling in plastic or metallic material.
  • PS E expanded polystyrene
  • glass wool or rock wool panels can be fixed to the support either by gluing, or by various devices of the staple type or pulling in plastic or metallic material.
  • the base layer consists of a coating in which a mesh-shaped reinforcement, generally made of fiberglass, is coated.
  • a mesh-shaped reinforcement generally made of fiberglass
  • the coating is applied in at least two passes, respectively a first pass for producing a relatively thin bonding layer spread over the external face of the insulating wall and on which the trellis is laid, the latter being then covered with a second thicker layer constituting the body of the coating.
  • the assembly is covered with a finishing coating itself consisting of at least one primary layer for the protection of the base layer and which is covered, most often, by a decorative layer.
  • an adhesive generally consisting of a paste composed of mineral fillers and additives associated with a resin and which is mixed with a certain proportion of cement.
  • the base layer also called undercoat, is intended for the coating and bonding of the reinforcement on the insulation. As this layer is applied to the insulation and exposed to the sun and cold, it must have a certain flexibility to resist differential expansions and that is why we generally incorporate a certain amount of resin into the coating. same product as for glue, by varying the cement dosages.
  • the paste contains a fine-grained mineral filler.
  • a primer before applying the topcoat.
  • the latter is generally in the form of a thick, grainy paste consisting of a mixture of mineral fillers and, optionally, colored pigments, in an organic binder.
  • the differential expansion is absorbed thanks to the flexibility of the reinforced base layer.
  • the three coatings are of different compositions, which can cause different tensions and a risk of cracking and delamination.
  • the bonding adhesive and the various coatings must be prepared separately at the time of their application and, before applying a layer, it is necessary to wait for the drying of the previous layer, which requires a time. quite long, varying according to atmospheric conditions, and which can go up to 48 hours.
  • Such a mortar contains a filler, a hydraulic binder, cellulose and a synthetic material, in particular a resin, resistant to alkaline products to obtain a water barrier effect.
  • a resin with a highly branched chain and therefore having a glass transition temperature is used. tively high.
  • the load must include a fairly large proportion of medium sand with a particle size of up to 5 mm and such a mortar therefore intended for the preparation of a fairly thick coating.
  • this mortar is prepared, as usual, by mixing dry products, then adding water for mixing.
  • this mortar is prepared, as usual, by mixing dry products, then adding water for mixing.
  • the subject of the invention is a new product for producing an insulating coating which does not have such drawbacks, and which, while retaining the advantages of known products, makes it possible to prepare a coating with high cohesive power and having, even in low thickness, very good qualities of resistance, impermeability, flexibility, adhesion to the support and external appearance.
  • the invention therefore relates to a thermal insulation coating intended to cover the external face of a support and comprising, in cross section, from the inside to the outside, a wall of insulating material fixed on the external face of the support and a coating plaster in which a lattice-like reinforcement is coated, said plaster consisting of a cement mortar containing, as main constituents, a filler consisting of a mixture of fine sand and sand medium, a hydraulic binder and a resin.
  • the coating is produced from two components which are kept separately and mixed in desired proportions at the time of application, respectively, a first component consisting of a cement mortar comprising the filler, the binder hydraulic and additives and a second component comprising the resin and additives, said resin being in aqueous dispersion and having a glass transition temperature close to 0 ° C., and the proportion of the second component being at least 30% of the amount cement contained in the first component.
  • an aqueous dispersion of vinyl copolymer is chosen in which the particle size is between 0.2 and 3 microns, and more preferably between 0.5 and 2 microns.
  • the setting time is relatively short.
  • the homogeneity of the coating is improved and, consequently, its cohesive power is higher
  • vinyl copolymers use is preferably made of copolymers of vinyl ester and of weakly branched ethylenic monomers, and more preferably, copolymers of vinyl acetate and ethylene.
  • a very important advantage of the invention lies in the fact that thin coatings are produced, generally between 3 and 7 mm, which have qualities superior to those of thick coatings without their drawbacks.
  • the coating according to the invention makes it possible to produce coatings having a traditional surface condition.
  • a minimum thickness of 3 mm of the coating according to the invention is sufficient to ensure the durability of the waterproofing.
  • the coating according to the invention has a capillary absorption significantly lower than that of a traditional coating coating.
  • the coating produced with the coating according to the invention exhibits good behavior when subjected to accelerated aging tests. Indeed, no blistering, discoloration, cracking, water passage, detachment and significant chalking of the surface type were observed.
  • the invention also covers the product developed for the preparation of this coating and consisting of two components kept separately, respectively:
  • a first component consisting of a cement mortar having the following composition by weight: 15 to 30% white or gray cement, 40 to 50% of fine sand with a particle size of up to about 0.5 mm, and preferably between 0.08 and 0.4 mm, 25 to 45% and, preferably, 25 to 35% of an average sand with a particle size between 0.5 and 1.5 mm approximately, and further containing a rheology agent, a water repellency agent and a thixotropy agent, and a second component consisting of a vinyl copolymer in aqueous dispersion whose glass transition temperature is between 0 and 5 ° C., added with an anti-foaming agent and a preservative, the active proportion, by weight, of the second component being from 30 to 35% of the amount of cement contained in the first component, these two components being kept separately, the resin being mixed with the mortar, in desired proportion, only at the time of use for the preparation coating.
  • the resin in aqueous dispersion provides sufficient water for the dilution, no addition of water being normally required.
  • the insulating coating which is applied to the outer face 10 of a support 1 such as a building wall comprises an insulating wall 2 consisting, for example, of polystyrene panels placed side by side, of a base layer 3 in which is incorporated a reinforcement 4 and a finishing coating 5 produced in at least one layer.
  • the panels constituting the insulating wall 2 are fixed to the support 1 either by means of staples or dowels, or by gluing. In that case, as shown in the drawing, there are on the outer face 10 of the wall 1, strips of adhesive paste 6 spaced from one another and to which the insulating panels 2 are applied by crushing the paste 6.
  • the panels 2 are then covered with a first layer of plaster 31 on which the mesh 4 is applied, then the latter is covered with a second layer 32 so as to be completely coated, the second layer 32 is then covered with the same product, projected by a compressed air device, for example.
  • the mesh 4 is made, as usual, of fiberglass or keylar with square meshes of 3 to 5 mm. As indicated above, to make the paste 6 and the base layer 3, the same coating consisting of two components mixed at the time of application, respectively a cement mortar and a resin.
  • the first component is a mortar preferably having the following composition: 15 to 30% and preferably 16 to 25% of cement white or gray, 40 to 50% of fine sand with a particle size of up to about 0.5 mm and preferably between 80 and 400 microns, 25 to 45% and, preferably, 25 to 35% of an average sand with a particle size ranging from 0.5 to 1.5 mm, up to 0.3% and preferably between 0.08 and 0.25% of a rheology agent such as a cellulose derivative, up to 0.2% and preferably between 0.05 and 0.15% of a water repellant and a thixotropy agent, for example short fibers, in a proportion such that the weight ratio of this thixotropy agent to the active fraction of the second component is at most equal to 10 % in weight.
  • the second component is a dilute resin with a low glass transition temperature combined with an anti-foaming agent and a preservative.
  • a vinyl copolymer is used, the glass transition temperature of which is between 0 ° C. and 5 ° C.
  • the two components are kept separately and mixed only at the time of application in proportions of 20 to 35% of resin relative to the amount of cement contained in the mortar, a proportion of 32% being particularly advantageous.
  • the amount of water contained in the second component is normally sufficient to adequately hydrate the hydraulic binder.
  • the presence of grains up to 1.5 mm secures the coating and the operation of the mesh inside the plaster and the presence a significant proportion, at least equal to 40%, of fine elements associated with a resin and with additives makes it possible to ensure the adhesion of the coating 3 to the insulating panels and to the mesh 4.
  • the presence of a large proportion of medium sand gives the coating a sufficient compressive strength to quickly apply another layer.
  • the same coating can be used to make the finishing coating 5, the proportions of fine elements and resin providing the plaster with the necessary flexibility while the proportion of medium sand gives it a traditional-looking surface finish.
  • the thermoplastic nature of the coating is less marked than that of the plastic coatings usually used and is less likely to fix ambient dust.
  • the use, as resin, of a vinyl copolymer having a low glass transition temperature (between 0 and 5 ° C) and in particularly high proportions compared to the hydraulic binder (30 to 35% of the amount cement) allows, when this resin is combined with the solid component, to prepare a perfectly homogeneous paste which gives a coating with very high cohesive power.
  • the coating according to the invention could however be used as an adhesive product for bonding the insulation to the support.
  • the same components can be used to produce a single coating having all the qualities required to constitute the adhesive product 6, the base layer 3 and the finishing layer 5 .
  • the layers 3 and 5 are in fact made up of the same product and that it is not necessary to wait for the complete drying of the base layer before apply the finish coating. On the contrary, it is even advantageous not to wait too long to apply the finishing layer 5 so as to improve its adhesion.
  • the product according to the invention makes it possible to produce thin coatings, generally between 3 and 7 mm and which however have excellent qualities of resistance, waterproofness, flexibility, adhesion to the support and external appearance.
  • the coating prepared from the two components defined above can advantageously be used as a simple finishing coating applied directly to the outside face of a wall.
