Multilayer bituminous-polymeric material and method for producing same

摘要

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. 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.
