Definitions

  • bitumen membranes are membranes with a carrier insert, e.g. Raw felt, glass fleece or fabric, jute fabric, man-made fiber fleece or fabric, which either only soaked with bitumen impregnating compound or additionally provided with cover layers of bituminous covering compound on both sides and sprinkled with mineral substances.
  • a carrier insert e.g. Raw felt, glass fleece or fabric, jute fabric, man-made fiber fleece or fabric, which either only soaked with bitumen impregnating compound or additionally provided with cover layers of bituminous covering compound on both sides and sprinkled with mineral substances.
  • bitumen itself is a semi-volatile, dark-colored mixture of various organic substances obtained during the processing of suitable petroleum, whose elastoviscous behavior changes with temperature.
  • the typical properties for bitumen are based on a colloidal system in which a phase (asphaltenes and petroleum resins) is present in a coherent (coherent) phase consisting of high-boiling oils (maltenes) in a stable distribution.
  • the asphaltenes and petroleum resins are not a uniform group of substances. You are the higher molecular weight parts in the bitumen and can be separated by suitable solvents.
  • the bitumen in the broadest sense also includes the bitumen portions of natural asphalt formed from petroleum in geological periods. Bitumen of this type is referred to as asphalt in the Anglo-Saxon language area (especially the USA).
  • bitumen is distinguished from asphalt.
  • asphalt is a naturally occurring or technically produced mixture of bitumen or bituminous binders and minerals as well as, if necessary, further aggregates and / or additives.
  • bitumen mixtures for the roofing industry which, in addition to the bitumen, contain neutralized sulfonated polymers and fillers (cf. US Pat. No. 4,371,641).
  • Bitumen mixtures of this type have the disadvantage that the content of polymer sulfonates on the one hand increases the water vapor permeability and on the other hand reduces the elasticity.
  • the invention relates to bitumen sheets, which are characterized in that they contain a proportion of synthetic silica in the bitumen impregnating composition and / or bituminous covering composition used for their production.
  • Bitumen membrane is understood to mean a bitumen membrane as defined in DIN 55 946.
  • the bitumen sheets according to the invention are preferably elastically modified bitumen sheets or polymer bitumen sheets. these can comply with DIN standards DIN 52 133 (polymer bitumen welding membrane), 52 128, 52 143, 52 130, 52 131, 52 132 and / or 18 190.
  • the bitumen impregnation composition can preferably contain a proportion of synthetic silica of 0.5 to 3.0% by weight, based on the bitumen impregnation composition.
  • the bituminous covering compound can preferably contain a proportion of synthetic silica of 0.5 to 5.0% by weight, based on the bituminous covering compound.
  • Both synthetic and pyrogenic silicas in particular those produced by flame hydrolysis, can be used as synthetic silicas.
  • the precipitated silica can have a BET surface area of 120 to 500 m2 / g. It can optionally be steam jet milled, spray dried or spray dried and milled. A spray-dried and ground precipitated silica is preferably used.
  • the pyrogenic, preferably flame-hydrolytically produced silica can have a BET surface area of 100 to 400 m 2 / g.
  • bitumen impregnating composition can preferably have the following constituents:
  • Bitumen preferably distillation bitumen, such as B 300, B 200, and / or B 80 in an amount of 53 to 70 wt .-%, based on the total mass.
  • Elasticity-improving substance preferably SBS, and / or EPDM rubbers in an amount of 2 to 15 wt .-%, based on the total mass.
  • the bitumen impregnating mass can contain other substances, e.g. Filler included.
  • Fillers such as Slate flour, limestone flour, fly ash, etc. are mineral, fine meal substances that are not soluble in water.
  • the proportion of filler can be from 0.1 to 15% by weight, based on the total mass.
  • bituminous covering compound can preferably have the following constituents:
  • Bitumen such as oxidation bitumen or distillation bitumen, preferably distillation bitumen e.g. of types B 300, B 200, and / or B 80 in an amount of 50 to 70 wt .-%, based on the total mass.
  • Elasticity-improving substance preferably SBS and / or EPDM rubber, regenerated rubber, plasticizer oil in an amount of 3 to 15% by weight, based on the total mass.
  • the bituminous covering compound may contain other substances such as fillers. Fillers such as slate flour, limestone flour, fly ash, etc. are mineral, fine meal substances that are not soluble in water.
  • the bituminous covering compound can contain further reinforcing materials, such as glass fiber, mineral fiber, steel fiber, plastic fiber and / or cellulose fiber.
  • the proportion of filler can be from 0.1 to 30% by weight, based on the total mass.
  • bitumen sheets according to the invention can be sprinkled with slate chippings, talc, green stone and / or quartz sand in a known manner.
  • bitumen sheets according to the invention can be produced by known methods.
  • the production can be carried out as described in the publication "bitumen and asphalt pocket book” 5th edition, 1976, page 96 ff, Bauverlag GmbH.
  • the bitumen sheets according to the invention have the advantage that the plasticity range has been significantly expanded. Ie, the temperature difference between low-temperature bending stability and heat resistance, which is determined on the sheets according to the invention in accordance with DIN 52 123, Part 2, is significantly increased by the use of synthetic silica. The heat resistance can be increased to 120 ° C. The addition of synthetic silica allows considerable savings to be made in known elasticity-improving substances, such as SBS rubber.
  • bitumen membranes according to the invention can be used as bitumen roofing membranes, bitumen roof sealing membranes, vapor barrier membranes, bitumen welding membranes and / or as underlay membranes for tile and asbestos cement roofs.
  • the softening point is carried out on the bituminous covering with a ring and ball test according to DIN 52 011.
  • bitumen sheets are produced in accordance with "bitumen and asphalt pocket book” 5th edition (1976), pages 96-98, the oxidation bitumen 85/40 being used as the bitumen impregnation mass.
  • a polymer bituminous covering compound with the following composition is used: 66% bitumen B 200 E. 10% rubber SBS 411 powder 2% precipitated silica 22 Sipernat® 22 S. 2% mineral fiber 20% slate flour Mixing time: 5.5 hours Temperature: 180 ° C Ring and ball value: 135 ° C Heat resistance 2 h / 120 ° C; passed Cold stability: -31 ° C passed
