日本住友橡胶工业株式会社在2015年第44届东京车展2015上展出了扎上钉子也不漏气的轮胎——CORESEAL。CORESEAL在轮胎胎面内侧涂覆了黏性密封剂,即使扎上钉子等异物,钉孔贯通到胎面内侧,密封剂也可以黏住钉子等异物,防止轮胎漏气。拔掉钉子后,密封剂会流入孔中堵住钉孔,防止轮胎漏气。 Japan’s Sumitomo Rubber Industries Co., Ltd. exhibited CORRALAL tires that were spiked with nails at the 44th Tokyo Motor Show 2015. CORESEAL is coated with adhesive sealant on the inner surface of the tire tread. Even if a nail and other foreign objects are stuck on the tire tread, the nail hole penetrates to the inside of the tread. The sealant can also stick foreign matters such as nails to prevent the tire from leaking. After unplugging the nail, the sealant will flow into the hole to block the nail hole to prevent the tire from leaking.
