摘要： A pneumatic tire in which a sealant layer has been formed based on a decomposition reaction of polyisobutylene and which has an excellent puncture-preventing function while avoiding any inconvenience aroused by the sealant layer formation. The pneumatic tire has a sealant layer in that region of the inner surface of the tire which corresponds at least to the tread. The sealant layer is made of a pressure-sensitive adhesive sealant obtained by heating a rubber composition containing 0.2 to 20 parts by weight of a peroxide per 100 parts by weight of a rubber ingredient comprising at least 50 wt.% of polyisobutylene and 0.2 to 20 parts by weight of a peroxide. A liquid ethylene/α-olefin copolymer, liquid polybutadiene, or liquid polyisoprene is added as a pressure-sensitive adhesive for the sealant layer in an amount of 5 to 50 parts by weight.

摘要： Disclosed are a pneumatic tire, which exhibits excellent puncture-preventing function while avoiding inconvenience aroused when a sealant layer is formed based on decomposition reaction of polyisobutylene, a process for producing the same and a sealant rubber composition. This pneumatic tire is provided with the sealant layer in a region of the inner surface of the tire which corresponds at least to a tread. The sealant layer is made of an adhesive sealant obtained by heating a rubber composition containing 0.2 to 20 parts by weight of peroxide per 100 parts by weight of a rubber ingredient containing not less than 50 wt. % of polyisobutylene. 5 to 50 parts by weight of a liquid ethylene/α-olefin copolymer, liquid polybutadiene or liquid polyisoprene are added as an adhesive of the sealant layer.
摘要翻译： 公开了一种充气轮胎，其具有优异的防刺破功能，同时避免了当基于聚异丁烯的分解反应形成密封剂层时引起的不便，其制备方法和密封剂橡胶组合物。 该充气轮胎在轮胎的内表面的至少与胎面相对应的区域中设置有密封剂层。 密封剂层由粘合剂密封剂制成，该密封剂通过加热含有0.2至20重量份过氧化物的橡胶组合物，每100重量份含有不少于50重量％ ％的聚异丁烯。 添加5〜50重量份液体乙烯/α-烯烃共聚物，液体聚丁二烯或液体聚异戊二烯作为密封剂层的粘合剂。
