Definitions

  • the invention relates to a moisture-adaptive vapor barrier according to the preamble of patent claim 1.
  • vapor barriers in the form of films are known to prevent the entry of moisture in the form of water vapor in a building structure.
  • Such films are characterized by a correspondingly high constant water vapor diffusion resistance, which in the construction practice is converted into the diffusion-equivalent air layer thickness (s d value).
  • the s d value is generally above 10 m, preferably at 100 m.
  • the water vapor diffusion resistance is usually measured according to DIN EN ISO 12572: 2001. Since in many cases a blocking of the moisture exchange through the vapor barrier, ie a non-drying, is undesirable, since this may be accompanied by a damage to the building structure, such vapor barriers are now replaced by vapor barriers.
  • vapor barriers are designed in their thickness and / or material by nature so as to allow moisture removal from the building structure.
  • wet-adaptive vapor barriers are known (see. WO 96/33321 A1 ), which are formed by a material in which the water vapor diffusion resistance decreases with increasing mean ambient humidity, ie, with increasing mean ambient humidity, the vapor barrier allows a larger water vapor transmission, the vapor barrier thus opens accordingly.
  • the wet-adaptive properties of the films are adjusted so that they have an average humidity of the atmosphere surrounding the vapor barrier of 30-50%, a water vapor diffusion resistance (s d value) of 2-5 m diffusion-equivalent air layer thickness and at a humidity of the environment in the range of 60-80% have a water vapor diffusion resistance (s d value) which is smaller than 1 m.
  • the inventors have recognized that, despite the enormous advantages of such a moisture-adaptive vapor barrier, improvements are required to enable improved adaptation of the moisture-adaptive properties of a vapor barrier to specific construction-specific requirements. For example. Due to the fact that the interior design moves more and more into the autumn and winter months occur in these construction measures increasingly wet situations in which an opening of the known vapor barriers is undesirable. In particular, in screed and drying of screed, where often the necessary interior ventilation is omitted, set to the film increased ambient humidities, which have the consequence that, at a time when the moisture-adaptive vapor barrier should close in principle, but this now opens due to the increased humidity within the building and thus allows a correspondingly higher moisture through the vapor barrier in the wooden structures.
  • the object of the invention is to provide a moisture-adaptive vapor barrier, which allows an adaptation of their moisture-adaptive properties to different construction-specific concerns.
  • the invention assumes that the diffusion resistance behavior of a moisture-adaptive vapor barrier is represented in an S curve when the s d value for the water vapor diffusion resistance is plotted above the ambient humidity.
  • the incoming S-leg of this S-curve in this case is up to a humidity of the environment of 50% to a diffusion resistance of 2 m for the diffusion-equivalent air layer thickness and above, then at greater ambient humidity, the curve with a substantially flat slope in the overflowing S-leg, which is then desirably at a level less than 1 m diffusion-equivalent air layer thickness at a humidity of the environment or atmosphere from 60%.
  • the adaptive functional layer at a humidity of the environment above 70% has a water vapor diffusion resistance which is ⁇ 1 m diffusion-equivalent air layer thickness, this has a desired steep turnaround area between the S-legs of the S d -value curve result, so that on the one hand to influence the opening of the vapor barrier due to the shift of the turning area along the abscissa to the right, ie the vapor barrier opens only at a higher ambient humidity for the water vapor passage, and on the other hand, the transition between closing and opening the film is much faster than in conventional non-inventively modified wet-adaptive vapor barriers.
  • the low water vapor diffusion resistance in the moisture-adaptive vapor barrier according to the invention would be present only at humidity values of the environment from 70%, that is, from values of ambient humidity which are generally not reached in the case of screed work in winter.
  • the required opening of the moisture-adaptive vapor barrier is guaranteed in summer so that then at any time a corresponding dehydration of the construction is guaranteed.
  • the curve shape can be adjusted to construction-specific features.
  • the incorporation of hydrophobizing agents ensures that moisture is incorporated into the moisture-adaptive functional layer with a delay, which is the cause of the moisture-adaptive behavior. This obstructed storage of water has the intended displacement effect.
  • this effect can also be achieved with the incorporation of hydrophilizing, ie water-absorbing agents, since the moisture is then bound and held by these hydrophilizing agents and the entry into the moisture-adaptive functional layer takes place only with delay.
  • hydrophilicizing agents it is expedient for entry into the moisture-adaptive functional layer if this incorporation takes place only in the surface region or near-surface regions of the vapor barrier or additionally or alternatively in a coating provided on the moisture-adaptive functional layer.
  • the entry into the moisture-adaptive functional layer can take place in total or additionally and alternatively also in the coating.
  • the turning region between incoming S-limb and expiring S-limb is shifted to the right by about 10% -points relative to the non-modified vapor barrier.
  • This is achieved by setting the vapor barrier to the values for the water vapor diffusion resistance mentioned in the claims.
  • the approximately parallel course of the incoming S-leg is extended to the right in the direction of the abscissa, ie, to increasing humidity, which then at the same time also increases at the given values for the higher humidity of the environment a steeper course of the turning region between the two legs of the S-curve different from the S-curves of conventional not correspondingly modified damp-adaptive vapor brakes leads.
  • the inflection point of the S-curve is at a humidity of the environment from 60% and above.
  • inflection point here is that point of the S-curve to understand where the incoming S-leg merges into the expiring S-leg.
  • the invention is based on the assumption that the two-dimensional s d profile has a s d value plotted on the ordinate and a moisture level plotted on the abscissa, which determines the functional relationship between the s d value and the mean relative to the vapor barrier humidity x , which is calculated from the relative humidity of the atmosphere applied to both surfaces of the vapor barrier, which forms the basis for the relevant humidity temporal behavior calculation programs in constructions.
  • the measuring instruction for the determination of a single value S d ( x ) is described in the international standard DIN EN ISO 12572: 2001, which is based on the formation of a dynamic equilibrium. Due to the fact that the basic measurement specification at the time of its development was designed for non-wet-adaptive vapor barriers, ie those with a substantially constant s d value, the current version of DIN EN ISO 12572: 2001 focuses on two particularly preferred points , the so-called wet cup and the dry cup.
  • the wet-cup is defined by two adjacent humidities of 50% and 93%, so that an average relative humidity of 71.5% is established, for the dry-cup 3% and 50% moisture are applied so that the mean 26 , 5%.
  • one of the two moistures in a vessel with a Salt while the second humidity is set with a controllable climatic chamber, so that other than the "classic" dry-cup and wet-cup ratios are adjustable. This is necessary in particular for moisture-adaptive vapor brakes, since the exact course of the function must be determined.
  • the DIN EN ISO 12571: 2000 contains a list of other salts, with which other moisture can be adjusted, so that any mean rel. Humidity and moisture gradients in the combination of salt and adjustable climate chamber are possible.
  • such a measurement curve should be determined, for example, in the form of an incremental measurement series. This conflicts with the practical problem that the measurement of a single point at s d values greater than 2-3 m can already take several weeks until the dynamic equilibrium has been established, so that the number of support points is measured in the form of measured value tuples S d (FIG. x ) is reduced to usually 5 to 7 in order to limit the total time required for the measurement to a period of 3 to 4 months.
  • These interpolation points are suitably distributed over the range of the mean humidity from 0 to 100%.
  • a test point distribution with 6 value tuples proven in practice is given: (3/50); (33/50); (33/65); (50/75); (50/93); (80/93).
  • the two numerical values represent the respective humidity of an atmosphere applied to the vapor barrier, so that mean relative humidity of 26.5%, 41.5%, 49%, 62.5%, 71.5% and 81.5% result.
  • the salts used are silica gel (3%), magnesium chloride (33%), sodium chloride (75%) and ammonium dihydrogen phosphate (93%). The opposite side is adjusted with a controlled climate chamber.
  • the measurement results ie, the value tuples, are evaluated in a least squares regression analysis using an approximation function to provide the database for the computational programs.
  • any function can be used.
  • Suitable programs are included in the known statistics program packages.
  • D stands for the asymptotic lower limit of the curve, ie in the case of a moisture-variable vapor brake approximately for s d, min , which follows from a limit analysis for x against ⁇ , taking into account the upper limit of the physically possible humidity range between 0 and 100%.
  • A stands for the spread of the function between minimum and maximum value, thus, in the case of the moisture-adaptive vapor barrier, the value S d, max is approximately A + D, which results from a limit analysis for x against - ⁇ and the restriction taking into account the lower one Barrier of the physically possible humidity range between 0 and 100% follows.
  • C indicates the location of the inflection point (C; A / 2 + D).
  • This equation system is not closed solvable. It is usually calculated using an iterative method starting from suitable starting values.
  • Fig. 1 of the WO96 / 33321A1 illustrated embodiment of a moisture-adaptive vapor barrier arise with the measured data tuple (26.5%; 4.5m); (41.5%, 3.8m); (62.5%; 1m); (71.5%; 0,44m); adds another parameter (90%, 0.1m) to the estimators for the parameters: A 4.7 Iteration step: 1 decimal place B 0,127 Iteration step: 3 decimal places C 52 Iteration step: 0.5 D 0.04 Iteration step: 2 decimal places
  • the vapor barrier can thus be adapted to different construction-specific conditions by shifting the inflection point of the S-curve from the usual moisture ranges of unmodified vapor barriers of less than 60% ambient humidity into an ambient moisture range of 60-70%, which is for the described winter construction situations is advantageous.
  • An adjustment of the transition point in the humidity range of 70-80% of the environment is advantageous when building structures have on the outside additional vapor-tight layers, such as in the form of a bituminous sheet, which hinders dehydration to the outside.
  • the curve of the moisture-adaptive vapor barrier up to ambient humidity of 50% above a s d value greater than 4 m diffusion-equivalent air layer thickness is, preferably greater than 5 m diffusion-equivalent air layer thickness.
  • the outgoing leg of the S curve of the moisture-adaptive vapor barrier has an s d value ⁇ 0.5 m from 75% ambient humidity, preferably from 70% ambient humidity. In conjunction with the aforementioned parameters, this results in a correspondingly steep curve in the turning region of the S-curve.
  • the moisture-adaptive functional layer itself is characterized in particular by a thickness in the range of 30 .mu.m to 100 .mu.m. Furthermore, the functional layer is expediently formed by a film.
  • the functional layer are layers or films made of polyamide; Polyvinyl alcohol, especially EVOH (ethylene-vinyl alcohol); Polyethylene copolymers with ionomers or polyethylene polyacrylic acid copolymers (in particular as a multi-layer structure) are suitable.
  • hydrophobizing or hydrophilizing agents the usual suitable agents can be used, such as fluorocarbons, fluorinated esters or silicone-based agents, in particular organic silicone compounds.
  • suitable hydrophilizing agents are polyethers, organic ammonium salts and organic acids.
  • a hydrophilizing or hydrophobizing agent and a deviating from the material of the functional layer material from said group of polyamide; Polyvinyl alcohol, especially EVOH (ethylene vinyl alcohol); Polyethylene copolymers with ionomers or polyethylene polyacrylic acid copolymers in question.
  • a coating of the film with hydrophilizing or hydrophobicizing agents it is expedient to provide the coating on both sides of the functional layer or the film when the functional layer is in the form of a film, so that the desired effect of the vapor barrier occurs independently of the installation position on site , A false construction of the vapor barrier is thereby impossible.
  • adhesion promoters based on oxirane-modified oligomers or polymers or diamines or diols can be used.
  • it is expedient to laminate the functional layer on one or both sides for example by a fleece, in particular glass fleece, or by suitable gel layers, such as mesh fabric u. like.
  • the profile of the s d values can be represented by the humidity in the case of moisture-adaptive vapor brakes in the form of an S curve
  • the steepness of the turning region between the incoming S-leg and the outgoing S-axis can be readily determined by suitable material parameters. Thigh desired set be, with a particularly steep course is preferred. This requires only conventional test series with the appropriate materials.
  • hydrophobing and hydrophilizing agents are added to a compound or batch for the production of a vapor barrier, for example based on polyamide, in the manufacture of the vapor barrier, whereby a uniform distribution of these agents within the moisture-adaptive functional layer achieves and results in a single-layer construction of the vapor barrier.
  • the application is carried out by an impregnation process in which the vapor barrier, which is preferably designed as a film, is passed through a bath so that the hydrophilizing or hydrophobicizing agent can be applied as a layer with the interposition of an adhesion promoter.
  • the spraying of the agent or the application of the agent in the manner of a coating dispersion is also suitable.
  • these production methods enumerated above are by no means to be considered as limiting.
  • Fig. 1 shows exemplary s d profiles for different vapor barriers.
  • Curves 1 and 2 depict the S-curve of conventional moisture-adaptive vapor barrier films whose inflection point is clearly visible below 60% ambient humidity.
  • the curve denoted by 3 represents the S-curve of a modified according to the invention damp-adaptive vapor barrier, in accordance with the basis of a vapor barrier film.
  • Curve 1 by incorporating hydrophobic agent into the moisture-adaptive functional layer has reversed the turning region of the curve to the right overall.
  • the S-curve 3 opens only at higher humidity of the environment.
  • the inflection point of curve 3, designated 4 is in the range of the mean relative humidity of 65%.
  • the diagram also shows that the curve 3 in the turning region is significantly steeper than the curves 1 and 2.
  • the base material for a one-layer vapor barrier film here are in particular polyamides, preferably Polyamide 6.
  • Polyamide 3, 4, 12 or 66 is likewise suitable.
