Definitions
- the present invention relates to a waterproofing membrane for roofing.
- a known waterproofing membrane typically comprises an upper layer of polymeric material which is arranged to reflect UV rays, a lower sealing layer which is arranged to cover a roof, and a frame disposed between said upper layer and said lower layer.
- WO 2004/070107 discloses a bituminous membrane which comprises an armature provided on a first side with a bituminous mass and on a second side of a mixture consisting of an acrylic polymer and titanium dioxide (T1O2).
- the layer comprising the mixture of acrylic polymer and T1O2 protects the membrane UV rays.
- the function of this layer is thus to form a barrier against UV rays so that the latter can not come into contact with the bituminous mass present on the first face of the armature.
- the reflective membrane is obtained by directly applying the mixture consisting of an acrylic polymer and T1O2 on the second face of the armature, which is then dried during the implementation of the membrane which is brought to the level of the bitumen bath where the first face of the frame can be impregnated with bitumen. Then, the membrane is dried again to obtain a final product.
- the mixture consisting of the acrylic polymer and TiO 2 may have a viscosity that varies, which may lead to the sedimentation of part of the constituents of the mixture. which is therefore not homogeneous enough.
- the dispersion of the T1O2 can no longer be guaranteed in the membrane. Therefore, the reflectivity of the membrane decreases over time thus making it less effective, when it covers the roof of a house or a building.
- the protective layer which comprises the acrylic polymer and TiO 2 which is not sufficiently dispersed in the mixture then no longer plays its role of barrier against the passage of UV rays.
- the object of the invention is therefore to overcome the drawbacks of the state of the art by providing a roof waterproofing membrane which has a longer service life compared to known membranes and which considerably reduces the risk associated with the phenomenon of exudation, when the membrane comprises bitumen.
- a roofing waterproofing membrane as indicated at the beginning characterized in that said polymeric material is bi-oriented.
- the use of a bi-oriented polymer material makes it possible to confer on the waterproofing membrane advantageous properties, especially in terms of mechanical performance, chemical resistance, UV protection and reflectivity. It is known to those skilled in the art that the absorption of UV radiation by a roofing membrane significantly reduces the service life of the latter. This phenomenon is due to degradation reactions that can occur at different layers of the roofing membrane. These degradation reactions come for example from photochemical reactions, oxidation or elevation of the temperature of the membrane. These degradation reactions may in some cases result in yellowing of said polymeric material. The degradation of the membrane can lead to the production of a membrane whose sealing is reduced.
- the absorption of solar rays by the membrane significantly increases the temperature of the building on which the membrane is fixed. This can help, for example, to increase the energy costs of building air conditioning in hot countries.
- Oxygen and water permeability of the membrane is also a factor to consider. Indeed, oxygen and water can contribute to the degradation of the membrane through reactions respectively of oxidation and hydrolysis.
- the use of a bi-oriented polymer layer may advantageously limit the permeability to oxygen and water of the membrane and thus limit the impact of the problems that result.
- Another advantage also lies in the fact that the oil that can be contained in the lower sealing layer, for example when it comprises bitumen, can be maintained in this layer during the lifetime of the membrane in order to avoid any migration of oil following the aforementioned phenomenon of exudation.
- This is a real advantage in that the environmental impact of the waterproofing membrane according to the invention is considerably reduced when it preferably contains bitumen.
- An additional advantageous characteristic lies in the fact that the upper layer made of a bi-oriented polymer material makes it possible to improve the adhesion between the latter and the other layers forming the sealing membrane according to the invention,
