Definitions

  • the present invention relates to a primer for waterproofing and / or circulation coating based on bitumen and / or asphalt, which can be used on construction works or buildings.
  • It also relates to coatings sealing and / or circulation formed using a such primary, as well as a method for carrying out such coatings on surfaces of works of construction or buildings.
  • a waterproof coating is an element continuous which can be obtained in particular by application to hot bitumen-based sheets comprising possibly one or more reinforcements, assembled together by flame welded or bitumen bonded covers heat melted, forming a bituminous membrane; through pouring asphalt continuously forming one or more overlapping layers; or by combining the two previous techniques.
  • a traffic liner also constitutes a continuous element formed on a roadway or construction such as a bridge deck, by deposit of a asphalt or bituminous concrete (mixture based on sand or pebbles stuck with bitumen) spread in layer (s) uniform (s) or by pouring asphalt, possibly over a waterproof coating.
  • a roadway or construction such as a bridge deck
  • a road surface must have particularly good resistance to deformation under the effect of repeated passage of vehicles, their acceleration or braking, good resistance to shocks, etc ...
  • the support is metallic, for example galvanized sheet steel, lead, aluminum or zinc, or based on hydraulic binder, by example in concrete or mortar, a primer is spread in thin layer on the surface of the support before the coating.
  • this primary can be multiple, this being used in particular for hanging the coating on the support, for temporary protection of the support against bad weather (rain, dew, etc.) in awaiting the completion of the final coating (s), impregnation to a certain depth from the surface when the support is porous, and as a medium prevent blistering of the waterproofing coating and / or circulation especially when the support is permeable gases, especially steam.
  • the blistering phenomenon is generally caused by the vaporization of moisture always present in permeable substrates such as concrete or cement mortar, under the effect of heating. This- last may be due to the sun, the coating often remaining exposed to it before the wearing course is not deposited. Warming up can also be due to the subsequent application of bituminous coating (s), which is carried out hot.
  • This vaporization is indeed accompanied by a increased gas pressures inside the protected structure, the pressure applying in particular on the lower surface of the waterproof coating.
  • bituminous coatings can peel off locally if the primary is not performing well enough, thus forming blisters of various sizes according to their rigidity and the pressure.
  • the origin of the heating which can cause the blistering phenomenon is therefore multiple, and this risk can manifest at different times during the sealing of a structure.
  • bituminous coatings whether they are coatings with based on bituminous sheets, based on poured asphalt or of mixed systems, are based on bitumen solubilized in solvents. Bitumen emulsions are also used and more rarely epoxy resins.
  • Bituminous primers which are monocomponents, wet the supports on which they are applied due to their surface tension, but have a low affinity for polar supports such as concrete or metal due to their low polarity.
  • these primers after drying, have a low internal cohesion and are highly thermoplastic. As a result, they do not effectively avoid blistering phenomena.
  • resin-based primers epoxies adhere well to polar supports such as concrete or metal, being themselves polar, and can therefore resist blistering. These primaries are also used especially for bridge decks intended for circulation.
  • the present invention has for objective of providing a one-component adhesion primer, making it possible to avoid the blistering phenomenon mentioned above, whatever the origin and the time of warming up.
  • Another object of the invention is to provide such a primary having at the same time a good affinity both with respect to polar supports such as concrete and bituminous coatings, not very polar, and allowing to obtain a satisfactory adhesion of the coating bituminous on such supports.
  • Yet another objective is to provide a primer that can be implemented in particular for construction and traffic works such as bridge decks and meeting requirements road surfaces.
  • the present invention relates to a coating sealing and / or circulation for construction or building, characterized in that it comprises at least one layer of adhesion primer comprising at least one polymer or one urethane copolymer in solution or dispersion including the chain has at least one group during anion, applied to the construction work or building surface to be protected, said surface constituting a polar support, and at least one layer of bituminous coating deposited on said layer (s) of primary, said polymer or copolymer allowing both the adhesion of the primer with bituminous coating, and with said work surface of construction or building by substantially eliminating the risks of blistering.
  • adhesion primer comprising at least one polymer or one urethane copolymer in solution or dispersion including the chain has at least one group during anion, applied to the construction work or building surface to be protected, said surface constituting a polar support, and at least one layer of bituminous coating deposited on said layer (s) of primary, said polymer or copolymer allowing both the
  • the invention also relates to a method to seal and / or provide a coating of circulation of a construction or building structure, characterized in that at least one layer of a adhesion primer as defined above, on the surface intended to be sealed and / or provided with a traffic coating, said surface constituting a polar support then in that we deposit at least one bituminous coating layer on said at least one primer layer (s).
  • a primary based on such (co) polymer allowed satisfactory adhesion to the times of the primary itself on a polar support such as concrete or metal, and bituminous coating on said primary, avoiding blistering phenomena, the primary here playing a role of the "intermediate connection or attachment "between the polar support and the bituminous coating.
  • the urethane polymers or copolymers with pendant polar groupings are examples of (Co) polymers useful for the purposes of the invention.
  • the adhesion primer according to this invention contains at least one polymer or copolymer in particular urethane, the chain of which has at least one grouping during polar, and able to form a film on a support formed by the surface of a structure construction or building intended to be protected.
  • This surface is generally based on material such as for example concrete, cement mortar and / or metals and constitutes a polar support.
  • the polar group during may consist of an anionic group such as carboxylic or sulfonic acid group.
  • These groups can be present in the polymer or copolymer used, in particular available in commercial, but polymers can also be used by external emulsification, using agents emulsification (surfactants).
  • the polymers or copolymers with internal emulsification are examples of the polymers or copolymers with internal emulsification.
  • Such (co) polyurethanes are known in the art. technical and can in particular be obtained by replacing the polyol constituent, or only a part thereof depending on the number of acid groups desired, by a monomer containing an acid group (carboxylic or sulfonic) while.
  • the anion centers are then generated before that the (co) polymer is in the form in particular of dispersion.
  • the number of polar groupings is chosen advantageously so that the primary presents good affinity with polar supports and that the polarity of the film is relatively weak in surface, once formed.
  • the basic structure of the (co) polymer used is relatively unpolar. It is advantageously compatible and refines with bituminous coating.
  • bituminous coating by bituminous coating, one hears a coating made from sheets bituminous and / or from poured asphalt, or bituminous coatings conventionally used for the surface course, such as asphalt bituminous.
  • the polymer or copolymer used may consist advantageously in an aliphatic chain polyurethane polyester, an aromatic polyurethane with a polyether chain or into an acrylic polyurethane copolymer.
  • the polyester chain aliphatic polyurethanes are particularly preferred.
  • the molecular weight of these polymers or copolymers is preferably greater than 1 million.
  • the primary according to the invention comprises at least a polymer or copolymer as defined above under form of solution or dispersion.
  • Brookfield viscosity of the solution or dispersion measured at 25 ° C, is advantageously included between 20 and 500 mPa.s.

  • this includes between 25 and 50% of (co) polymer and has a pH located between about 7 and 10.
  • the polymer or copolymer is advantageously insensitive to water.
  • this (co) polymer must be substantially non-thermoplastic at processing temperatures bituminous coatings, especially below 150 ° C.
  • the primer can comprise a mixture of (co) polymers as defined above or a mixture at least one of said polymers with one or more others (co) polymers such as (co) polymers acrylic.
  • the primer according to the invention forms a thin film polar substantially impermeable to gases and in particular to water vapor, unlike bituminous primers known.
  • the primary according to the invention is intended to be used for the protection of supports, in particular in concrete, construction works or buildings. he can be implemented using coating techniques classics.
  • the primary according to the invention is particularly well suited for the realization of bridge decks or certain wide tracks circulation because this adhesion primer can lead in particular to total adhesion of the bituminous coating support, which makes it possible to satisfy all the better resistance requirements of such road surfaces to deformation and horizontal forces, in particular braking.
  • the primary according to the invention is particularly advantageous due to the adhesion of the coating on the support which it provides, which may allow in particular to avoid training risks or to improve impact resistance.
  • At least one layer of primer is deposited of adhesion as defined previously on the support the more often made of concrete, then we realize the bituminous coating in a conventional manner, according to a 'or several superimposed layers.
  • the coating formed on the support using primary according to the invention can constitute a simple waterproofing coating for example when applied on a building surface, in particular a roof or a terrace, this covering then comprising a membrane bituminous and / or a layer of poured asphalt.
