    • A sealant laminate (30) comprising a first layer (36) of a sealant material, a first layer (38) of a non-sealant material that is positioned radially outward of the first layer (36) of the sealant material, a second layer (40) a sealant material that is positioned radially outward of the first layer (38) of the non-sealant material, a second layer (42) of a non-sealant material that is positioned radially outward of the second layer (40) of the sealant material, and a third layer (44) of a sealant material that is positioned radially outward of the second layer (42) of the non-sealant material is disclosed. The first and second layers (38, 42) of non-sealant material prevent the first, second, and third layers (36, 40, 44) of sealant material from contacting each other. Also, a pneumatic tire (10) comprising such a sealant laminate (30) positioned between an outer surface (11) and an inner surface (13) of the tire and a method of manufacturing such a tire (10) is disclosed.

    • The present invention is directed to a pneumatic tire (10) with a built-in sealant layer. The tire (10) comprises an outer circumferential rubber tread (14), a carcass (16), and an innerliner layer (22) disposed radially inwardly from the carcass (16), wherein the tire comprises a built-in sealant layer (20, 20A, 21) comprising a polyurethane based sealant material, wherein the built-in sealant layer (20, 20A, 21) is positioned between the carcass (16) and the innerliner layer (22), and wherein the built-in sealant layer (20, 20A, 21) is a multilayered composite layer, the multilayered composite layer comprising a first polyurethane layer (21), a second polyurethane layer (21 A) and an intermediate layer (20A) positioned between the first and second polyurethane layer (21, 21A). The intermediate layer (20A) comprises at least one of:
      (A) a non-woven microfiber layer containing polyurethane,
      (B) particulate pigment,
      (C) discrete fibers,
      (D) cured rubber particles, and
      (E) a woven microfiber layer containing polyurethane.

      Also, a method of manufacturing a non-woven microfiber layer containing polyurethane using as intermediate layer (20A) is disclosed.
    • 本发明涉及一种充气轮胎(10)配有一个内置的密封剂层。 轮胎(10)包括外周橡胶胎面(14),胎体(16),并且在从所述胎体(16),沿径向向内设置的内衬层(22),其中所述轮胎包括一个内置的密封剂层(20 ,20A,21),包括基于聚氨酯的密封剂材料,worin内置密封剂层(20,20A,21)的胎体(16)和所述内衬层(22)之间,并且其中定位在所述内置密封剂层 (20,20A,21)是一种多层复合层,该多层复合层包括第一和第二聚氨酯层之间设置的第一聚氨酯层(21),第二聚氨酯层(21 A)和中间层(20A)( 21,21A)。 中间层(20A)包括以下的至少一个:(A)的非织造微纤维层包含聚氨酯,(B)粒状颜料,(C)的离散纤维,(D)固化的橡胶颗粒,和(e)一编织的超细纤维 含有层聚氨酯。 所以,制造非织造微纤维层使用如中间层(20A)是圆盘含游离缺失聚氨酯的方法。
