Definitions

  • the invention relates to a multilayer bituminous-polymeric material comprising a base, an upper layer and a lower layer, which have different operational properties, as well as to a method for producing the said material.
  • the invention may be used for the production of a roll roofing material exhibiting water-proofing and fire-retardant properties.
  • bituminous and bituminous-polymeric materials are produced by dipping a base into a coating basin with a hot bituminous-polymeric mixture with the result that a layer of a homogenous binding material is applied on the upper and the lower sides of the base.
  • the upper and the lower layers of such a material are exposed to external influences differing as to their types and degree: the upper layer is mostly subjected to mechanical loads, solar radiation, and flame in a case of a fire, and the lower layer is subjected to tensile forces generated by base strains.
  • the issue of producing a multilayer roll bituminous-polymeric material having the upper and the lower layers different in their compositions and properties.
  • RF Patent No. 2117578 , B32B 11/04, E04 D 5/12, publ. 08/20/1998 describes a multilayer material for the protection of coatings applied to construction buildings and structures.
  • the said material comprises a support (base) coated with bituminous layers on both sides and an upper protective layer that, for the purpose of improving performance, may comprise filling and modifying agents.
  • the said material is produced by passing a support through melted bitumen and then applying an upper protective layer by rolling, with subsequent cooling the produced material.
  • the said Patent does not teach how exactly the upper protective layer is applied and whether it comprises an agent improving fire-retarding property, in particular.
  • the closest analogous solution to this invention are a bituminous-polymeric material exhibiting fire-retardant properties and a method for producing same, which are described in EP 0634515 , D06N 5/10, E04D 5/10, publ. 09/18/1996.
  • This material comprises a reinforcing base of a thermoplastic material, which both sides are coated with an impregnating compound improving its (i.e., base) stability to a thermal or mechanical influence, a fire-retardant or fireproof material (fire-retarding agent) applied on the impregnated reinforcing base and exhibiting fire-retarding and fireproofing properties activated at a temperature of 300°C or higher, a weldable lower layer of a polymeric bitumen that may comprise one or more filling agents, and an upper layer that may be selected from a group of materials including bitumen, polymeric bitumen, plastomeric artificial material and elastomeric artificial material, the upper layer being able to comprise one or more filling agents.
  • the proposed method for producing the above material includes the following production steps: a reinforcing base is impregnated with an impregnating compound raising the base stability to thermal and/or mechanical action; a fire-prevention or fireproof material (fire-retarding agent) is applied to the upper side of the impregnated reinforcing base; the upper and the lower layers are applied to the impregnated reinforcing base which upper side is already coated with a fire-prevention or fireproof material (fire-retarding agent).
  • a fire-prevention or fireproof material (fire-retarding agent) is applied to the upper side by scattering it over the upper side mechanically, or in an electrostatic field, or with the use of an adhesive.
  • the said method may include an additional operation of scattering a mineral bulk material over the upper and/or the lower layer or coating same with a cover film.
  • Disadvantages of the known material include the fact that a fire-retarding agent is not used in the mixture forming the upper layer. First, a fire-retarding agent is applied to the base, and then the thus applied layer of the fire-retarding agent is coated with the upper layer which, in this case, has no fire-retarding properties. This makes the material performance poorer in this respect.
  • a disadvantage of the method for producing the known material is that it includes relatively many steps, which is conditioned by the presence of a separate operation of applying a fire-retarding agent to the upper surface of the base in advance, and then applying the upper layer to the already applied fire-retardant material, which complicates the process of producing the finished material and, hence, lowers productivity and increases the cost of the finished product.
  • the technical effect of the claimed invention in respect of the method is development of a method (production process) for producing a multilayer bituminous-polymeric material which upper and lower layers differ from each other by their compositions and properties, the said method simplifying the process of production of the finished product and improving productivity of equipment.
  • the technical effect of the claimed invention in respect of the multilayer bituminous-polymeric material is simplification of making and production of a material which upper layer exhibits prominent fire-retardant properties.
  • the claimed material comprises a base, an upper and a lower layers, wherein a nonwoven polyester cloth or a glass fabric or a glass cloth is used as the base, and the upper layer comprises a roofing bitumen or a mixture of a roofing bitumen and a paving bitumen, a polymeric modifier, a fire-retarding agent and a mineral filler, they all being mixed, and the lower layer comprises a mixture of a roofing bitumen, a polymeric modifier and a mineral filler.
  • the BNK40/180 or BNK45/190 bitumen is used as the roofing bitumen
  • the BND 60/90 or BND 90/130 bitumen is used as the paving bitumen
  • the amount of a roofing bitumen or a mixture of a roofing bitumen and a paving bitumen for the upper layer is from 45% to 75% by weight
  • the amount of a roofing bitumen for the lower layer is from 35% to 65% by weight.
  • a butadiene-styrene thermoplastic elastomer (SBS modifier) is used as the polymeric modifier for the upper and lower layers, wherein its amount for the upper layer is from 0.5% to 15% by weight, and for the lower layer from 2% to 15% by weight.
  • Dolomite or granite powder or talc is used as the mineral filler for the upper and lower layers, the respective amount for the upper layer being from 20% to 55 % by weight and for the lower layer from 30% to 55% by weight.
  • Thermally expanding graphite in the form of flakes in fraction from 0.1 mm to 3 mm and in the amount from 0.5% to 15% is used as a fire-retarding agent.
  • a nonwoven polyester cloth with the density from 100 to 300 g/m2 or a glass fabric with the density from 120 to 250 g/m2 or a glass cloth with the density from 40 to 110 g/m2 is used as the base, the base width being from 0.95 m to 1.1 m.
  • the claimed method consists in drawing the base, treating it with an impregnating compound, squeezing it, then applying the upper and lower layers to it, a nonwoven polyester cloth or a glass fabric or a glass cloth being used as the base;
  • the lower layer is made as a mixture consisting of a roofing bitumen, a polymeric modifier and a mineral filler
  • the upper layer is in the form of a ready mixture comprising a roofing bitumen or a mixture of a roofing bitumen and a paving bitumen, a polymeric modifier and a mineral filler;
  • the upper layer being applied to the base through a diffuser, and then the formed material is passed through size rolls for producing material of required density and thickness.
  • the claimed method for producing a double-layer bituminous-polymeric material according to the claimed compositions and ratios of the components forming the claimed material may be implemented as follows.
  • the base 1 being a nonwoven polyester cloth with the density from 100 to 300 g/m2 or a glass fabric with the density from 120 to 250 g/m2 or a glass cloth with the density from 40 to 110 g/m2 is drawn through an impregnating basin 2, where it is impregnated with an impregnating compound being a low-viscosity compound based on bitumen and modifying additives with or without a fire-retarding agent.
  • An exemplary compound a roofing bitumen (BNK 40/180) - 90-97 % by weight; SBS (styrene-butadiene-styrene) modifier - 2-6% by weight; a fire-retarding agent (thermally expanding graphite) - 1-4 % by weight.
  • BNK 40/180 a roofing bitumen
  • SBS styrene-butadiene-styrene
  • a fire-retarding agent thermalally expanding graphite
  • the base After application of an impregnating compound the base is squeezed in squeezing rolls 3 and goes further to an application roll 4 arranged in a coating basin 7 comprising a prepared mixture forming the lower layer of the produced material.
  • the lower layer representing a mixture of a roofing bitumen, a polymeric modifier and a mineral filler is applied to the lower surface of the base with the use of the said application roll 4.
  • the amount of a roofing bitumen in this mixture is from 35% to 65 % by weight, that of a polymeric modifier from 2% to 15 % by weight, and that of a mineral filler from 30% to 55 % by weight.
  • the upper layer comprising, all of them being pre-mixed, a roofing bitumen or a mixture of a roofing bitumen and a paving bitumen, a polymeric modifier, a fire-retarding agent and a mineral filler, the amount of a roofing bitumen or a mixture of a roofing bitumen and a paving bitumen being from 45% to 75% by weight, that of a polymeric modifier from 0.5% to 15 % by weight, that of a mineral filler from 20 to 55 % by weight, and that of a fire-retarding agent from 0.5 to 15 % by weight.
  • the upper layer is prepared as follows.
  • a hot bitumen is added to a mixer at a temperature ranging from 180 to 200°C, then an SBS modifier is loaded, mixing takes place for 40-60 minutes in circulation: the mixer - a homogenizer - the mixer.
  • a mineral filler is added to the mixer, and mixing continues for 15-20 minutes at a temperature ranging from 180 to 190°C, and then a thermally expanding graphite is added to the obtained mixture.
  • a mixture forming the lower layer is produced similarly, but without adding a thermally expanding graphite.
  • the produced mixture is fed on the base 1 through a diffuser 5 being a headbox arranged above the base, to which the produced mixture is fed continuously during the operation time of the process line.
  • the lower part of the diffuser is provided with a slot which width is equal to the base width and from which the mixture uniformly flows to the base surface, thus ensuring uniformity and homogeneity of the base upper layer.
