Definitions

  • the invention relates to nonwovens and cover materials made therefrom, which are particularly tear-resistant and dimensionally stable, and to processes for their production.
  • Spunbonded nonwovens made from polymers and nonwoven fabrics made from synthetic fibers or mineral fibers are known per se.
  • the nonwovens made from the fibers are first subjected to a mechanical treatment for felting or mechanical pre-consolidation of the fibers.
  • the pre-consolidation takes place via a needling process, a calender treatment or, in the case of nonwovens made from various synthetic fibers, via a heat treatment to melt the fibers.
  • These nonwovens treated in this way are then impregnated with crosslinkable polymers in order to give the nonwovens the desired strength after drying and crosslinking of the polymers.
  • Nonwovens that have been coated in an additional process step are also referred to as carrier nonwovens. They are used in many technical areas.
  • German Offenlegungsschrift 3 001 075 describes the addition of silica sol as a filler to a latex without increasing it Chalking comes on the surface of the needle punch carpet made with this mixture.
  • glass fibers are coated with aqueous solutions based on silica sol to increase the chemical resistance and storage stability before the nonwoven is manufactured.
  • nonwovens made of polymers and synthetic or mineral fibers, which are solidified with polymers or resins are used on an industrial scale, in particular as carrier materials for covers.
  • the requirements regarding strength and dimensional stability under load and the effects of temperature on the nonwovens are high, so that particular care was taken to ensure that the fiber structure of the nonwoven, the pre-consolidation and the chemical final consolidation are optimal and coordinated with one another. Despite these measures, the dimensional stability under load and the effects of temperature is still insufficient.
  • nonwovens which are sufficiently dimensionally stable even under extreme loads and exposure to temperature, so that they can be used in the area of covering materials such as e.g. roofing membranes, sealing materials can be used.
  • the invention relates to nonwovens made of synthetic fibers and crosslinked polymer and SiO2 in a weight ratio of 3: 1 to 1: 3, preferably 2: 1 to 1: 2 or melamine resin and SiO2 in a weight ratio of 10: 1 to 1: 1.
  • Another object of the invention is a process for the production of nonwovens by needling, calender treatment or heat treatment of spunbonded nonwovens or nonwovens made from polymers or synthetic fibers, subsequent processing of these treated nonwovens with aqueous solutions or dispersions of crosslinkable polymers or melamine resins to form a nonwoven with subsequent drying , the solution or dispersion additionally or instead of part of the polymers or melamine resins, contains silica sol in an amount such that the weight ratio of polymer to SiO2 is 3: 1 to 1: 3, preferably 2: 1 to 1: 2 or the weight ratio of melamine resin to SiO2 is 10: 1 to 1: 1 is.
  • the nonwovens according to the invention can be used as sealing materials, for example in dam construction or for landfills.
  • Another object of the invention are carrier webs made of the webs according to the invention with a coating of bitumen or PVC plastisol.
  • Another object of the invention is a process for the production of backing nonwovens by needling, calender treatment or heat treatment of spunbonded or fiber nonwovens made from polymers or synthetic fibers, subsequent processing of these treated nonwovens with aqueous solutions or dispersions of crosslinkable polymers or melamine resins and subsequent drying, whereby the solution or dispersion additionally or instead of a part of the polymers or melamine resins contains silica sol in such an amount that the weight ratio polymer to SiO2 is 3: 1 to 1: 3, preferably 2: 1 to 1: 2 or the weight ratio melamine resin to SiO2 10 : 1 to 1: 1, and after processing the fleece is coated with bitumen or PVC plastisol at temperatures of 160 to 230 ° C.
  • the carrier webs according to the invention are preferably used as covering materials, such as e.g. roofing membranes and sealing materials used for dams and landfills. Due to the high dimensional stability, these materials can be used under extreme weather conditions, such as large temperature fluctuations.
  • Polyamide fibers (nylon fibers), polyolefin fibers or preferably polyester fibers, particularly preferably polyester fibers based on p-terephthalic acid and ethylene glycol, are preferably used as synthetic fibers.
  • Mineral fibers for example glass fibers, can also be used.
  • Aqueous dispersions of crosslinkable polymers based on styrene-butadiene or acrylate and various crosslinking components or aqueous solutions of modified melamine resins are preferred.
  • the crosslinkable polymers used as binders must have thermosetting properties.
  • the thermosetting behavior of the binder is achieved by selecting suitable monomers or by incorporating crosslinking components in the polymers. Therefore, copolymers and terpolymers of acrylic acid esters, acrylamides and acrylonitrile as well as styrene and butadiene are particularly preferred.
  • the melamine resins are usually modified by condensed amidosulfonic acid, caprolactam or diethylene glycol.
  • acids or latent acid donors are preferably added to the polymer dispersions and catalytically active pH-neutral salts or latent acid donors are preferably added to the melamine resin solutions.
  • the dimensional stability of the nonwoven or the covering material is significantly improved both under load and with simultaneous, increased exposure to temperature, the other properties remaining the same or in some cases also being improved.
  • the fibers and the binder are preferably used in a fiber: binder (dry) weight ratio of 10: 0.1 to 10: 3.5, particularly preferably 10: 0.5 to 10: 2.5.
  • the covering materials preferably 0.5 to 3.5 kg / m2 of coating material are applied.
  • the preferred silica sols are colloidal solutions of amorphous silicon dioxide in water, which are also referred to as silica sols or silica sols.
  • the silicon dioxide is in the form of predominantly spherical particles which are hydroxylated on the surface.
  • the particle diameter of the colloid particles is 1-100 nm, the specific BET surface area correlating to the particle size (determined according to the method of GNSears, Analytical Chemistry Vol. 28, N. 12, 1981-1983, December 1956), 50-1000 m 2 / g is.
  • the alkaline stabilized silica sols have a weakly alkaline pH and contain small amounts of Na2O, K2O, Li2O or ammonia or alkali or ammonium aluminates as alkalizing agents.
  • Silica sols can also be weakly acidic as semi-stable colloidal solutions. It is also possible to use cationically adjusted silica sols by coating with Al2 (OH) 5Cl.
  • the concentrations of the silica sols are preferably 5 to 60 wt .-% SiO2, in particular 15 to 50 wt .-% SiO2.
  • a spunbonded polyester fleece based on p-terephthalic acid and ethylene glycol of approx. 150 g / m2 is pre-consolidated by a needling process.
  • this fleece is placed in the above Dipped mixture and then squeezed to a moisture absorption of 150 g / m2 (20% solids based on dry fleece). It is dried at 150 to 160 ° C.
  • the foam is applied to a spunbonded nonwoven made of polyester continuous filaments of approx. 170 g / m2, which has previously been pre-consolidated by calendering, in such a way that a wet application of approx. 170 g / m2 remains on the nonwoven after pressing and vacuuming. It is dried at 150 to 180 ° C.
  • the nonwovens from Examples 1 to 3 are compared with nonwovens without the addition of SiO2.
  • the fleeces of Examples 1 and 2 have approximately the same strength values (measured at room temperature) as those without the addition of SiO2.
  • the elongation values at 180 ° C. of the nonwovens 1 and 2 according to the invention are approximately 20% above the values of the nonwovens according to the prior art.
  • the strength value of the fleece from Example 3 was 10% higher than that of the corresponding fleece without SiO2.
  • the elongation values were approximately the same.
  • bitumen roof covers produced with the nonwovens according to the invention have better elongation behavior and greater dimensional stability under the influence of temperature than the nonwovens produced without SiO2 and coated with bitumen.
