Definitions
- the present invention relates to a beam material which is used primarily for construction purposes, for example under tiled roofs, behind curtain walls, etc., for sealing against rainwater, snow, dust, soot, etc.
- Finished kraft papers with and without thread reinforcement are also offered as lining material. Although these have a sufficiently high water vapor transmission coefficient k D of up to 26 mg / m 2 hPa, they are insufficient in terms of mechanical strength, so that they can easily break or tear during processing. In addition, they are easily flammable.
- fabrics and nonwovens coated with soft PVC are also used as the underlay material, which, however, have a water vapor transmission coefficient k D of, for example, 0.065 mg / m 2 hPa, so that special, complex ventilation structures are necessary to prevent the formation of condensation.
- the present invention was therefore based on the object of providing an underlay material which does not have the disadvantages mentioned above.
- the underlay material according to the invention is now characterized in that it is both tear-resistant, permeable to water vapor, watertight and flame-retardant and consists of synthetic, normal or flame-retardant, organic or inorganic fibers in the form of a sheet which is water-repellent and, if appropriate, impregnated with a flame-retardant.
- the material preferably has a water vapor transmission coefficient k D of at least 12 mg / m 2 hPa and a tensile strength of at least 250 N / 5 cm, achieves combustion class V according to VKF and remains sealed for at least 20 hours under a water column of at least 40 mm.
- Such a material includes any of condensation or condensation of, is excellent in the stress occurring tear and mascarareissfesti g ness on, is waterproof and flame resistant. For easy installation, it is advisable to use the material in sheet form.
- Nonwoven fabrics are particularly suitable as fabrics, but also fabrics and knitted fabrics.
- the flat structure preferably as a non-woven fabric, can be selected in such a thickness that additional thermal insulation is achieved.
- the fabric can be impregnated waterproof and flame-retardant or made from appropriately pretreated fibers be put. If flame-retardant fibers are used, flame retardant treatment is generally not necessary.
- a flat structure such as a dense fabric, knitted fabric or non-woven fabric, e.g. a nonwoven fabric of preferably 1.5 denier fine synthetic, normally or flame-retardant, organic or inorganic fibers, e.g. Polyester or polyacrylic fibers or glass fibers, etc. impregnated with a mixture of flame-retardant, hydrophobic and binding agents by known methods, e.g. by dipping and squeezing and then drying. However, the mixture can also be applied with a doctor blade or sprayed on under pressure.
- Particularly suitable flame retardants are organic halogen compounds, such as chlorinated paraffins, polyvinyl chloride and bromine compounds, in a mixture with antimony oxide and aluminum hydroxide. Phosphorus compounds can also be used, especially organic ones, which cannot be washed out.
- Suitable hydrophobicizing agents are e.g. Emulsions containing paraffins, fat-modified synthetic resins, silicones or fluorocarbons.
- the nonwoven or the woven or knitted fabric can be provided with a water vapor permeable, compressed foam layer before impregnation.
- a Such a layer can be applied in a known manner, for example by applying a foam compound in a coating process and then compressing the fabric coated on one or both sides.
- a compatible hydrophobizing agent for example an aqueous fluorocarbon
- a tangled nonwoven web consisting of polyacrylic fibers with a titer of 1.5 denier, which are needled with the finest needles in such a way that a uniformly dense needle felt of approximately 2 mm thickness and a weight of 150 to 160 g / m 2 is produced in immersed in an impregnation trough in an impregnation liquor and then squeezed between foulard rollers, so that the absorption of the fleece in the impregnation liquor is approximately 290% of the fleece weight.
- the impregnation liquor has the following composition:
- the web After squeezing between the foulard rollers, the web is dried in a tenter in the hot air duct, it being important to ensure that the web is tensioned only to a minimum.
- the temperature in the hot air duct rises from 100 ° C at the entrance to 150 to 160 ° C at the exit. In order to achieve good drying, a high level of air circulation and an appropriate air supply and discharge are necessary. In a 13 m long canal you can drive at around 6 m / minute. After leaving the channel, the web is cooled and rolled up.
- the product obtained in this way which can be produced in almost any color by appropriate selection of the pigment dyes, has good tear and tear propagation strengths of 350 N / 5 cm in the longitudinal direction and 250 N / 5 cm in the transverse direction or 20 N in the longitudinal and 15 N in the transverse direction , has a thickness of 1.5 mm and, after testing by the Association of Cantonal Fire Insurers (VKF), reaches fire class V.
- the measured water vapor transmission coefficient k D is 23 mg / mh Pa.
- the product resists two weeks of irrigation in the laboratory without allowing water to pass through. It is also heat, cold and light resistant.
- a compound of the following composition is first produced by homogeneously mixing with a high-speed stirrer:
- This mixture is foamed to 200 g / liter by blowing in air using a continuous foam mixer and with a doctor blade on a roller 0.7 mm thick onto a thermally bonded random web of polyethylene terephthalate fibers with a weight of 120 to 130 g / m 3 and Spread a thickness of 0.3 to 0.4 mm, dried in a hot air duct of 13 m length at 70 to 135 ° C and compressed immediately after leaving the heating duct in the warm state with a roller under a pressure of 6 bar.
- the web speed is 6 m / minute.
- Example 1 As in Example 1, it is impregnated and dried.
- the material obtained has similar properties in terms of water vapor permeability, tear resistance and flame resistance to that from Example 1, but an increased water resistance of over 20 hours under a 100 mm water column.
- the flow behavior of the impregnating compound is set so that it does not completely but only about penetrates to 2/3 of the thickness, resulting in a coverage of approximately 330 g impregnant (na ss) yields per m 2. If this were to penetrate completely through the fleece, the wet fleece would slip on the rubber blanket and would no longer be transported without warping.
- the fleece coated in this way is guided into a tenter frame shortly after the rubber blanket with the least possible longitudinal and transverse pull and dried in the hot air duct at a rising temperature of 150 to 170 ° C and condensed at 170 ° C for about 50 seconds. Following the heating duct, the still warm material is smoothed with a roller under 6 bar pressure.
- the back (second side) is then coated in the same way. It is advantageous if the impregnating composition has a slightly lower viscosity than that for the front (first side).
- the amount of impregnation compound applied is approximately 640 g (wet) per m 2 .
- the impregnation compounds are prepared as follows:
- the raw water is first acidified with acetic acid and 100.00 parts by weight of it is stirred with the "Ukaprint K" (dispersant) until a homogeneous solution is obtained.
- Alumina hydrate and pigments are homogeneously dispersed in this solution using a high-speed stirrer.
- 41.8 parts by weight or 221.8 parts by weight for the second side of the acidified raw water are added, then the polyacrylic dispersion, then the decabromodiphenyl oxide / antimony oxide dispersion and finally the fluorocarbon Dispersion, pre-mixed with the remaining 20.00 parts by weight of acidified raw water.
- Adhering to the mode of operation is very important for the stability of the mixture, which should be stirred well before use.
- the product obtained according to Example 3 has the following properties: tear resistance in the longitudinal direction 448 N / 5 cm, in the transverse direction 404 N / 5 cm.
- the tear resistance is 15 N in the longitudinal direction and 17 N in the transverse direction.
- the measured water vapor transmission coefficient k D is 21 mg / m 2 h Pa.
- the material is sealed under a water column of 100 mm for over 20 hours. Firing class V according to VKF, even at 200 ° C.
- An impregnation mixture consisting of flame-retardant and hydrophobizing agents is knife-coated onto a thermally bonded nonwoven web consisting of polyethylene terephthalate fibers, as described in Example 2, with an air knife so that the fleece fibers are completely enclosed by the impregnation mixture.
- the application quantity is approximately 460 g (wet) per m 2.
- the drying frame is then dried in the hot air duct at a rising temperature of 150 to 180 ° C.
- a second coating point with a "doctor blade on a steel roller” mechanically by blowing air into 300 to 350 g / liter foamed mixture consisting of aqueous self-crosslinking polyacrylic dispersion of flame retardant and hydrophobic agents, pigments and foam stabilizer in a thickness of 0.5 to 0.6 mm, corresponding to approx.
