Definitions

  • the present invention relates to a multi-layer, flame-retardant carrier sheet and its production and to a bituminized roofing and sealing sheet containing this carrier sheet.
  • carrier sheets for roofing and waterproofing membranes which concern their further processing into roofing and waterproofing sheets and the behavior of the latter during and after laying on the documents.
  • High strength of the carrier web in a wide temperature range is intended to ensure high processing and dimensional stability when bituminizing and the fire behavior, assessed according to DIN 4102, Part 7, is to be met.
  • the carrier sheet should also ensure high dimensional stability of the finished roofing and waterproofing membrane when laid on the roof or other substrates, as well as high flexibility and a certain degree of elasticity to compensate for irregularities and weather-related dimensional changes of the covered substrate.
  • Carrier sheets for bituminized roofing and waterproofing sheets are described, for example, in European laid-open publications 0 176 847 and 242 524. They preferably consist of two nonwovens, for example a glass fiber mat and a polyester fiber mat, which are connected to one another by needling. The needled laminate is then finally consolidated with a binder, acrylate-butadiene or acrylate-butadiene-styrene copolymers being generally used.
  • German Offenlegungsschrift 26 19 087 e.g. described for polyester spunbonded binders, consisting of an acrylate-butadiene-styrene copolymer with an addition of 5 to 30 wt .-% of a melamine-formaldehyde precondensate.
  • a method for producing flame-retardant nonwovens is known from German patent specification 11 49 688.
  • a flame retardant is applied to the nonwoven at the same time as the binder.
  • tetrahydrophosphonium chloride is used as the flame retardant, which is applied together with a binder system composed of natural rubber latex and a melamine-formaldehyde precondensate.
  • the fleece is also solidified with a melamine-formaldehyde precondensate.
  • the nonwovens equipped in this way are poorly suited for the production of flame-retardant bitmunised roofing and waterproofing membranes in accordance with DIN 4107, Part 7, since for this purpose they must contain a very large amount of flame retardants, for example antimony trioxide or phosphorus compounds. This high proportion of flame retardants leads to a very strong reduction in the flexibility of the nonwovens, so that in this respect they no longer meet the requirements for the production of roofing and waterproofing membranes.
  • flame retardants for example antimony trioxide or phosphorus compounds.
  • the present invention now relates to a carrier sheet for the production of roofing and sealing sheets which does not have the disadvantages of the known materials, in which high mechanical stability is combined with very good fire behavior even at elevated temperatures.
  • the carrier web according to the invention consists of a glass fiber mat and a hat made of synthetic fibers, which are needled together and which are finally consolidated with a polymer-free, low-formaldehyde melamine-formaldehyde precondensate.
  • the glass fiber mat contained in the carrier web according to the invention can in the usual way with the usual binders, i.e. usually polymer binders or melamine resins are pre-consolidated.
  • the synthetic fiber fleece contained in the carrier web according to the invention can be made from all types of synthetic fibers which have sufficient strength.
  • synthetic fibers which have sufficient strength.
  • aliphatic and aromatic polyamides, polyacrylonitrile and in particular polyester fibers are suitable.
  • fiber types that have high strength, high modulus and low heat shrinkage, so that the dimension of the carrier web remains constant during further processing to form roofing and waterproofing membranes.
  • a particularly preferred synthetic fiber material consists of polyethylene terephthalate, especially the high-strength and low-shrink types.
  • the synthetic fiberylies consist of flame-resistant polyesters.
  • Examples of commercially available synthetic fibers from which the Synthetic fiber fleece can be constructed are (R) Trevira, in particular the high-strength types and the flame-retardant type (R) Trevira CS.
  • the synthetic fiber fleece can be constructed from staple fibers, advantageously with cutting lengths between 1 and 100 mm, or from continuous fibers. Tangled nonwovens made from continuous fibers are particularly preferred, in particular types which have undergone a certain degree of pre-consolidation through a calendering process, such as e.g. the so-called spunbonds.
  • the low-formaldehyde melamine-formaldehyde precondensate with which the carrier web according to the invention is finally consolidated has a molar ratio of melamine to formaldehyde of 1: 1.0 to 1: 3.5, preferably 1: 1.2 to 1: 3.
  • the partially etherified precondensates are partially etherified with lower alkanols, ie those with 1 to 4 carbon atoms, but especially with methanol.
  • the degree of etherification of the partially etherified precondensates is characterized in that they have 0.2 to 0.85, preferably 0.6 to 0.8, mol of ether groups per mole of formaldehyde.
  • Particularly preferred low-formaldehyde partially etherified melamine-formaldehyde precondensates have a molar ratio of melamine to formaldehyde of 1: 2 to 1: 3 and have 0.6 to 0.8 mol of methyl ether groups per mol of formaldehyde.
  • Sulfamate-modified low-formaldehyde melamine-formaldehyde precondensates contain, based on solid resin, 1 to 20% by weight, preferably 5 to 15% by weight, of sulfamate, calculated as sodium sulfamate.
  • Particularly preferred sulfamate-modified melamine-formaldehyde precondensates have a molar ratio of melamine to formaldehyde of 1: 1.2 to 1: 2 and, based on solid resin, have 5 to 15% by weight sulfamate, calculated as sodium sulfamate.
  • the melamine-formaldehyde precondensate contained in the carrier web according to the invention additionally contains a small amount, i.e. 1 to 5% by weight, based on solid resin, contains further modifying agents, in particular modifying agents which increase plasticity, as long as this does not unduly reduce the necessary flame resistance.
  • Plasticizing additives of this type are e.g. Di- and triethylene glycol and their ethers or polyethylene glycols with molecular weights up to 2000.
  • carrier webs according to the invention which are solidified with a melamine-formaldehyde precondensate without additional plasticizing modifiers.
  • Carrier webs according to the invention which have a combination of several preferred features are also particularly preferred.
  • the carrier web according to the invention has the advantage over known carrier webs that it exhibits improved fire behavior with a high degree of flexibility which is very accommodating for further processing. In this respect, it is considerably superior to both the nonwoven materials known from DE-AS 1 149 688 and the nonwoven materials produced using a binder according to DE-OS 26 19 087.
  • the mechanical load-bearing capacity of the carrier web according to the invention under the influence of heat (temperature range, e.g. 180 ° C.), as occurs during further processing into roofing and waterproofing membranes, has also been significantly improved.
  • the same applies to the tear propagation resistance of the carrier web according to the invention which is increased by approximately 25% compared to carrier webs which are finally consolidated with polyacrylate binders.
  • one of the above specified is used Synthetic fiber nonwovens needled with an optionally pre-consolidated glass fiber fleece and then with an aqueous melamine-formaldehyde precondensate of the above-mentioned specification, to which approximately 0.5 to 3% of a known hardener, for example a hardener based on p-toluenesulfonic acid, has advantageously been added Spraying, splashing or, preferably, dipping impregnated to the required resin absorption of 5 to 40, preferably 15 to 30,% by weight, based on unimpregnated material, optionally squeezed out and then dried in a heating oven, generally at temperatures between 80 to 200, preferably 120 to 180 ° C, hardened in the course of 5 to 30 minutes.
  • the production of the carrier web according to the invention is also the subject of the present patent application.
  • the carrier web according to the invention can be used for very different purposes with particular advantage. It can e.g. can be used as a decoration support due to their flame retardancy. Their use as a carrier material for bituminized roofing and waterproofing membranes is particularly preferred.
  • the use according to the invention of the low-formaldehyde melamine-formaldehyde precondensates specified above also offers advantages in the production of the carrier web according to the invention: namely, glass nonwovens with a relatively low binder content can be used. Since the character of the binder plays a minor role when the binder content is low, e.g. cheaper glass fleeces with a lower binder content, which do not have to be flame-retardant, can be used.
