近来用沥青橡胶油膏与聚合物油膏制成的非卷材式屋面材料日益发展。这种新式材料比传统的沥青油毡优越性大,能减少材料的多层性、容重轻、便于施工机械化、电不需要经常维修。苏联屋面材料科学研究所近来已将原有的沥青-丁基橡胶双组分冷膏(商品名“BeHTa”)改良成商品名为“BeHTa-y”的单组分油膏, Recently, non-coiled roofing materials made of asphalt rubber ointment and polymer ointment have been increasingly developed. This new type of material is superior to traditional asphalt linoleum, can reduce the multi-layer material, light weight, ease of construction mechanization, electricity does not require regular maintenance. The Soviet Institute of Roofing Materials has recently improved the original bitumen-butyl rubber two-component cold paste (trade name “BeHTa”) to a single-component grease called “BeHTa-y”.
