PROBLEM TO BE SOLVED: To provide a puncture-preventing agent, which can prevent a puncture hole at the moment of puncture and maintain an air pressure of a tire over a long period of time, to over come the problem that conventional puncture- preventing agents, which fill a puncture hole by intrusion of an adhesive into the hole, cannot maintain an air pressure of a tire during a long-term use and need continual pumping-up. SOLUTION: The puncture-preventing agent is obtained by mixing together water, fine polyethylene particles, carboxymethyl cellulose, a carboxyvinyl polymer, ethylene glycol, methyl para-oxybenzoate and ammonium dicyclohexyl nitrite and subsequently thickening the mixture by adding thereto diethanolamine, or by mixing together water, a nylon fiber, a polyester fiber, diatomaceous earth, a carboxyvinyl polymer, methyl cellulose, ethylene glycol and methyl para-oxybenzoate and subsequently thickening the mixture by adding diethanolamine thereto. |
