Definitions
- the present invention relates to a moisture variable protective layer, a process for producing the same, an insulating material and an insulation system comprising the moisture variable protective layer and the use of the moisture variable protective layer.
- Thermal insulation of building envelopes plays an increasingly important role in terms of both the insulation of the roofs and the walls. Insulation on the outside of the building is desirable but not always possible. Often, the space is simply not available, for example, if the buildings are directly adjacent to public land such as roads or sidewalks. Also monument protection etc. can prevent an external insulation.
- insulation systems must be as thin as possible on the inside of the building, be it in the wall or in the roof insulation with high insulation performance at the same time to minimize the loss of space through the insulation.
- the insulating material on the existing wall (fixed for example by means of adhesive mortar) and the moisture-variable layer on the side facing away from the existing wall of the insulating material.
- Film systems as moisture-variable layer have the disadvantage that adhesion to the film is not given.
- a stator construction is required, for example of wood or metal, which represents an undesirable thermal bridge.
- other commonly existing layers such as reinforcing mortar, fine plaster etc. do not adhere to the film, so that a further substructure, for example made of wood and plasterboard is required, which takes up more space and a large represents design effort.
- the present invention provides a moisture-variable protective layer, which is characterized in that at a relative humidity of 10% and a temperature of 12 to 35 ° C, the Sd value is at least a factor of 5.0 higher than the Sd value at a relative humidity of 90% and a temperature of 12 to 35 ° C wherein the moisture-variable protective layer was applied by means of a liquid-applied coating composition.
- the moisture-variable protective layer is characterized in that at a relative humidity of 10% and a temperature of 16 to 26 ° C, the Sd value by at least a factor of 5.0 is higher than the Sd value at a relative humidity of 90% and a temperature of 16 to 26 ° C wherein the moisture-variable protective layer by means of a coating composition liquid-applied.
- the factor is met if the measurement is fulfilled at a relative humidity of 90% and a relative humidity of 10% at any temperatures in the specified range, preferably the factor is fulfilled if the measurement is at a relative humidity of 90% and a relative humidity of 10% at the same temperature.
- the moisture-variable protective layer is characterized in that at a relative humidity of 10% and a temperature of 23 ° C, the Sd value is at least a factor of 5.0 higher than the Sd value at a relative humidity of 90% and a temperature of 23 ° C. wherein the moisture-variable protective layer is applied by means of a coating composition.
- the moisture-variable protective layer also adheres well to rockwool etc. and forms a closed film (light microscope).
- further layers which are usually applied on the inside, such as, for example, reinforcing mortar, plaster, etc., adhere well to the moisture-variable protective layer, so that stand constructions etc. are unnecessary.
- the moisture-variable protective layer of the coating composition is applied directly to the insulating material or, if present, to a coating of the insulating material.
- the moisture-variable protective layer is therefore preferably applied without the use of a carrier layer.
- the moisture-variable protective layer is characterized in that at a relative humidity of 10% and a temperature of 12 to 35 ° C, preferably 16 to 26 ° C, more preferably 23 ° C, the Sd value at least by a factor of 5, 0 is higher than the sd value at a relative humidity of 90% and a temperature of 12 to 35 ° C.
- the Sd value at a relative humidity of 90% and a temperature of 12 to 35 ° C, preferably 16 to 26 ° C, more preferably 23 ° C is usually between 0.01 m and 4.5 m, preferably between 0, 01m and 2.5m, more preferably between 0.01m and 1.5m, and most preferably between 0.01m and 1.0m.
- the coating composition contains a plastic.
- the coating composition is preferably in the form of an aqueous-based plastic dispersion, a reactive resin or a solution polymer.
- the plastic is preferably selected, more preferably consists of polyvinyl alcohol, ethylene-vinyl alcohol copolymers, partially saponified polyvinyl acetate, partially saponified ethylene-vinyl acetate copolymers, polyvinyl butyral, homopolymers or copolymers of (meth) acrylates, vinyl ethers, polystyrene, styrene acrylates, styrene butadiene, Butadiene, polyvinylamines, polyamides, polyamino acids, terpolymers of ethylene, vinyl alcohol and (meth) acrylates, terpolymers of ethylene, vinyl alcohol and vinyl ethers, reactive resins based on polyurethane, epoxides, acrylates or polyurea. Particularly preferred reactive resins are polyurethanes based on MDI prepolymers and polyureas based on MDI prepolymers and / or polyetheramine.
- the term includes (meth) acrylate, both acrylates and methacrylates.
- the plastics can optionally be crosslinked.
- the coating composition is an aqueous-based plastic dispersion and contains
- plastic 10 to 90% by weight of plastic, preferably 20 to 70% by weight of plastic, more preferably 25 to 60% by weight of plastic
- pigments 0 to 10 wt.% Rheology additives based on the plastic dispersion on an aqueous basis. If the composition contains other components in addition to plastic and water, the proportion of plastic and water is reduced in equal parts. If, for example, 20% by weight of filler and pigments are present, the proportion of plastic and water is in each case from 10 to 70% by weight.
- the plastic preferably contains, more preferably, polyvinyl alcohol, ethylene-vinyl alcohol copolymers, partially hydrolyzed polyvinyl acetate, partially hydrolyzed ethylene-vinyl acetate copolymers, polyvinyl butyral, (meth) acrylate homopolymers or copolymers, vinyl ethers, polystyrene, styrene acrylates, styrene butadiene, butadiene , Polyamides, polyamino acids, terpolymers of ethylene, vinyl alcohol and (meth) acrylates, terpolymers of ethylene, vinyl alcohol and vinyl ethers, particularly preferred are partially saponified polyvinyl acetate, (meth) acrylate homo- or copolymers and polyamides.
- the plastic is selected from
- the coating composition may contain up to 10% by weight of organic solvents.
- organic solvents are usually selected from alcohols, esters, ethers, and ketones, but also oils such as linseed oil or mineral oil fractions. Reactive solvents are also possible, e.g. Crosslinking and Polymerizing Systems.
