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.
  • 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 not only increases the softening point, but also improves the flexibility at low temperatures.
  • the elasticity of the bituminous mass is increased.
  • the lower aging resistance of these double bond-containing polymers, in particular against UV radiation, is a drawback.
  • the addition of polyolefins such as polyethylene has a more favorable effect on aging behavior, but an improvement in cold flexibility is generally not achieved and the elasticity is only slightly improved.
  • the range of plasticity of polymer bitumen, which has been modified with elastomers, is between 125 and -35 ° C and for olefin-modified ones between 150 and -15 ° C.
  • the range of plasticity is roughly the same, but shifted by about 25 K. This is just as important for the selection of a roof sealing membrane as the adhesive and welding behavior or the resistance to chemicals and aging.
  • 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.
  • 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 / m 2 ) is impregnated 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 of styrene-butadiene rubber and on both sides with a mixture of 63 Parts by weight of distilled bitumen B 200, 7 parts by weight of styrene-butadiene rubber and 30 parts by weight of slate powder coated with a grain ⁇ 100 gm in a thickness of 1 mm each.
  • the upper side is sprinkled with slate chippings (grit ⁇ ottp "1.5 mm) and the underside with fine sand.
  • the web passes through an electron accelerator and is irradiated with a radiation dose of 16.104 Gy.
  • a radiation dose of 16.104 Gy One of each of the irradiated and the non-irradiated material was Sampled and examined, the results are in the Table 1 compared.
  • 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 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 made 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 thickness 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. 10 4 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 / m 2 ), 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 talcized.
  • the 6th 10 4 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.
