Definitions

  • the invention relates to a bituminous roofing membrane modified with polymers.
  • Bituminous trays for roof waterproofing consist of a carrier material, such as foils, nonwovens or fabric, which may be impregnated with bitumen and which is coated on at least one side with a bituminous covering compound.
  • the surface of the covering compound is provided with a release agent that prevents the web from sticking when rolled up and, if necessary, can also perform other functions, such as protection against UV rays in the top layer of the roof waterproofing.
  • the bituminous coverings are modified with bitumen-compatible polymers. They increase the plasticity range and the viscosity of the melt. The addition of rubber and rubber-like polymers in addition to increasing the softening point, improves cold flexibility at the same time.
  • DD 215 559 proposes to improve the dimensional stability of bitumen mixtures by adding radiation-crosslinked polymers, in particular polyethylene, even at higher temperatures.
  • the degree of crosslinking should be chosen so that there is still sufficient solubility of the crosslinked polymer in the bitumen, since highly crosslinked polymers can therefore be considered fillers which only slightly change the properties of the bituminous compositions.
  • the crosslinking increases the molar mass of the polymer, which is known to have a positive effect on the softening point, but negative on the breaking point and penetration (road and highway, 1986, pages 3 - 9).
  • the bitumen mixtures according to the invention are primarily intended for road construction. This is also evident from the bitumen selection in the examples, which names the bitumen types B 50 and B 80 that are unsuitable for roofing membrane coverings.
  • the object of the invention is to provide an aging-resistant, with hot and cold adhesive bituminous adhesives roofing membrane which has an expanded plasticity range, which includes the polyolefin and rubber-modified bitumens.
  • a roofing membrane which consists of a carrier material which is coated on at least one side with a covering material made of polymer bitumen and optionally impregnated with bitumen materials, the covering material comprising a bitumen / rubber mixture in the ratio of bitumen to rubber between 17/3 and 19 1 contains and has been radiation cross-linked after manufacture of the web.
  • All bitumen-compatible and radiation-crosslinkable natural or artificial rubbers such as styrene-butadiene rubber and polybutadiene, can be used as the rubber.
  • Backing materials are all the usual nonwovens, scrims or fabrics made of glass or temperature-resistant synthetic fibers or also foils made of metal or plastic that is not degradable when cross-linked.
  • the fiber webs are preferably impregnated with bitumen, that too can be modified with a polymer that can be crosslinked by electron beams.
  • the backing material is coated on both sides with the crosslinkable covering compound.
  • the surfaces can be sprinkled with mineral release agents or laminated with foils, as is usual with roofing membranes depending on the intended use.
  • Bituminous hotmelt or cold adhesive layers can also be applied before or after the irradiation. However, it is also possible to coat the underside of the carrier material directly with the bituminous adhesive. Welding tracks of this type are known from DE-OS 30 42 943, but their upper cover layer consists of a vulcanized rubber mixture with a low bitumen content.
  • a polyester fiber fleece (230 g / m2) is made in a conventional plant for the production of bituminous roofing membranes with a mixture of 90 parts by weight of distilled bitumen B 200 and 10 parts by weight Impregnated styrene-butadiene rubber and distilled on both sides with a mixture of 63 parts by weight Bitumen B 200, 7 parts by weight of styrene-butadiene rubber and 30 parts by weight of slate powder coated with a grain size ⁇ 100 ⁇ m, each 1 mm thick.
  • the top is sprinkled with slate chippings (grain ⁇ ⁇ ⁇ 1.5 mm) and the bottom with fine sand.
  • the web then passes through an electron accelerator and is exposed to a radiation dose of 16.
  • the plasticity range (temperature range between the cold resistance of the web according to DIN 52123 and the softening point (RuK) of the covering compound according to DIN 52011) has been expanded by irradiation in both directions and has increased by 70 K.
  • the softening point is above the usual olefin-modified masses.
  • Example 1 is repeated, the proportion of the styrene-butadiene rubber in the impregnating composition and the covering composition being replaced by the same amount of polybutadiene.
  • the results are compared in Table 2.
  • the plasticity range has increased by 161 K and in both directions exceeds the plasticity range of the irradiated web according to Example 1.
  • roofing sheets according to the invention according to Examples 1 and 2 are outstandingly suitable for bonding with a hot bitumen or a bituminous cold adhesive.
  • a cold self-adhesive roofing membrane is produced from a polyester fiber fleece (230 g / m2) impregnated with a blown bitumen 85/40, which has a 1 mm thick covering compound according to Example 1 on the top and a 1 mm thick compound on the underside 65 parts by weight of distilled bitumen B 200, 11 parts by weight of synthetic rubber, 8 parts by weight of rosin and 3 parts by weight of an extender.
  • the top is then sprinkled as in Example 1 and the bottom covered with siliconized paper.
  • the track is 8. 104 Gy, as described in Example 1, irradiated.
  • the adhesive strength of the underside of the web does not decrease. The cold glue therefore remains unchanged during the irradiation.
  • a welding track is produced from a glass fiber fleece (100 g / m2), which is impregnated as in Example 2 and coated on the top.
  • the underside is covered with a 1 mm thick layer of blown bitumen 100/30.
  • the top is then sprinkled with slate chippings and the bottom is talcated.
  • the 6th 104 Gy irradiated web can be welded onto all common substrates like an untreated welding web, so hot-melt adhesive is not changed by the irradiation.
