FLAT TIRE REPAIRING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a flat tire repairing agent showing reliable can-stability and excellent flat tire repairing performance by adding vinylon short fibers to a blend of natural rubber latex and synthetic rubber latex. SOLUTION: The flat tire repairing agent is composed of a natural rubber latex and a synthetic rubber latex with vinylon short fibers added. The synthetic rubber in the synthetic rubber latex is, for example, a styrene-butadiene copolymer rubber(SBR), an isobutylene rubber(IR) or the like, and the blending ratio (solid content weight) of the natural rubber latex to the synthetic rubber latex in the blend is preferably 80/20-20/80. The vinylon short fibers are preferably of such characteristics that the diameter is 50-100μm; the length is 1-5 mm; the complete water-soluble temperature is 70 deg.C or more and the content ratio of the vinylon short fibers is 1-15 pts.wt. to 100 pts.wt. aqueous solution containing 40 wt.% or more (solid content) blend. The aqueous solution contains 40-70 wt.% (solid content) blend.
