Definitions

  • the invention relates to a curable composition with two constituents, one liquid and the other solid in the form of particles, in particular powders, which are mixed at the time of use.
  • the invention also relates to the use of such a composition as isophonic and isothermal coating and resistant to corrosion and to chemical agents.
  • the liquid phase comprises, on the one hand, a plastic resin in solution or in suspension in water and, on the other hand, an anionic agent capable of forming bubbles with a compound of the solid component, while this solid component comprises, in addition to said compound capable of reacting with said anionic agent, a compound capable of solidifying on contact with water.
  • the plastic resin is chosen from the group comprising vinyl acetate-vinyl versatate copolymers, acrylic ester-vinyl versatate-vinyl acetate terpolymers and styrene-acrylic compound copolymers.
  • the anionic agent of the liquid component is the condensation product of a sodium lauryl ether sulfate and an alcohol comprising from 12 to 14 carbon atoms, while the associated compound of the solid component is sodium ethylhexyl sulfate .
  • the constituent of the solid component capable of solidifying on contact with water and plaster, possibly with a setting retarder. Anti-fire charges can also be provided in the composition.
  • this prior composition has the disadvantage, as established by the Applicant while continuing its work, of cracking as it ages, whatever the environment. Due to a shrinkage of the resin, cracks appear in the coatings made of such a composition, with the consequence of forming thermal bridges and a serious deterioration of the thermal insulation properties of the coating.
  • the present invention aims to remedy these drawbacks by proposing a composition of the same general type as the previous composition mentioned above, but which does not exhibit any aging phenomenon and which can be used at very high temperatures, up to 1000 ° C, without altering or detaching from any support.
  • the invention also aims to propose a composition of this type in which cement and plaster can be present simultaneously, the incompatibility of which is well known, without the risk of these two components dissociating after hardening.
  • the invention finally aims to propose a composition of this type which can be used in very thin layers, around 3 to 4 mm thick, as a soundproofing and isothermal covering.
  • the subject of the invention is a curable composition with two constituents, one liquid, the other solid in the particulate state, which is mixed at the time of use, the liquid constituent comprising a resin. and a plasticizer in solution or in suspension in water, while the solid component comprises a compound capable of causing the expansion of said resin, and fillers,
  • this composition being characterized in that said resin and said plasticizer are respectively a modified acrylic copolymer and an acrylic plasticizer, and in that the solid constituent contains, in% by weight, approximately 30 to 60% of plaster, approximately 52 to 4% of cement and, as agent of compatibility between these two products, 3 to 7% of titanium or aluminum oxide.
  • Additives known per se may be incorporated in the liquid component as well as in the solid component, for example, antistatic products, germicidal and algicidal compounds, fire-resistant products, setting retarders, etc.
  • the solid component will contain aluminum powder or expanded mica.
  • the aluminum or expanded mica particles rise to the free surface, before the composition hardens, to then contribute to thermal insulation by reflection of infrared radiation.
  • the solid component may contain lead.
  • modified acrylic copolymer it is advantageous to use, in the liquid component, a salt of versatic acid.
  • the content of modified acrylic copolymer in the liquid component will be about 10 to 30% by weight, while the content of acrylic plasticizer will be about 1 to 6%. Under these conditions, the liquid constituent, with its possible additives, will be in the form of an emulsion which is perfectly stable over time.
  • the proportions of plaster and cement of the solid constituent, as well as the nature of these compounds, will vary according to the physical properties required of the coating.
  • the plaster content will generally be 30 to 60% by weight and the cement content from 52 to 4%, while the content of titanium oxide or aluminum oxide will be between 3 and 7%.
  • the particle size of the solid particles is approximately 0.3 to 2.5 mm.
  • This powder ready for use, is also stable during storage.
  • the solid component At the time of use, about 100 parts by weight of the solid component are mixed with 140 parts by weight of the liquid component and mechanical mixing is carried out.
  • the application is carried out using a worm type spraying machine, which ensures the mixing of the paste while allowing an expansion of the resin.
  • the mixture can also be laid, like a mortar, with a trowel or any other conventional device in the building industry.
  • the composition according to the invention hardens very quickly, since it takes only a quarter of an hour to obtain appreciable surface hardening, against two and a half hours with a composition according to the aforementioned patent application FR 79 03347.
  • a layer with a much smaller thickness is sufficient than with conventional insulators.
  • the external temperature of the coating is 58 ° C.
  • a 3.5 mm thick layer provides excellent sound insulation on the order of 20 decibels between the medium and the treble.
  • composition according to the invention adheres to any type of support, for example to a metallic surface, even polished, to glass or to dry or wet plaster, and it can optionally be applied in several superposed layers. It can be used with advantage for any type of sound or thermal insulation, both on machines and on building facades.
  • insulating plates can also be used to glue insulating plates and to protect these plates, which can be made of cellular or expanded materials, for example cellular glass or expanded polystyrene.
  • a composition in accordance with the invention is for example the following (% by weight): Liquid component
  • algicidal germicidal compound 1% - Chlorinated paraffin emulsified with an oxyethylenated alkylphenol and an aliphatic polyether (anti-fire product): 1% - Water: q. s. p.
