Abstract

The present invention provides a tire puncture sealing agent having excellent storage performance, and a tire puncture repair kit. The tire puncture sealing agent of the present invention contains: a rubber latex and/or a resin emulsion; a predetermined glycol ether; and a non-ionic surfactant having an HLB value from 15 to 20.

Claims (21)

1. A tire puncture sealing agent comprising:

at least any of a rubber latex and a resin emulsion;

a glycol ether represented by Formula (A); and

a non-ionic surfactant represented by Formula (B) and having an HLB value from 15 to 20:

R 1 —O—(CH 2 CH 2 O) n —R 2   (A)

R 3 —O—(CH 2 CH 2 O) m —H  (B)

where R 1 represents a monovalent aliphatic hydrocarbon group having from 1 to 5 carbon atoms, n represents an integer from 1 to 5, and R 2 represents an alkyl group or a hydrogen atom,

where R 3 represents a monovalent aliphatic hydrocarbon group having from 8 to 20 carbon atoms, and m represents an integer of 6 or greater,

and wherein said non-ionic surfactant is selected from the group consisting of polyoxyethylene stearyl ether, polyoxyethylene lauryl ether, and polyoxyethylene alkyl ethers.

2. The tire puncture sealing agent according to claim 1 , wherein the tire puncture sealing agent comprises 1 to 60 parts by mass of the non-ionic surfactant per total 100 parts by mass of a solid content of the rubber latex and a solid content of the resin emulsion.

3. The tire puncture sealing agent according to claim 1 , wherein, in Formula (A), R 1 has 1 carbon atom.

4. A tire puncture repair kit comprising the tire puncture sealing agent according to claim 1 .

5. The tire puncture sealing agent according to claim 2 , wherein, in Formula (A), R 1 has 1 carbon atom.

6. A tire puncture repair kit comprising the tire puncture sealing agent according to claim 2 .

7. A tire puncture repair kit comprising the tire puncture sealing agent according to claim 3 .

8. A tire puncture sealing agent comprising:

a mixture of a rubber latex and a resin emulsion;

at least one glycol ether selected from the group consisting of ethylene glycol monomethyl ether, diethylene glycol monomethyl ether and triethylene glycol monomethyl ether; and

a non-ionic surfactant selected from the group consisting of polyoxyethylene stearyl ether, polyoxyethylene lauryl ether, and polyoxyethylene alkyl ethers having an HLB value from 15 to 20, said non-ionic surfactant having the formula R 3 —O—(CH 2 CH 2 O) m —H, where R 3 represents a monovalent aliphatic hydrocarbon group having from 8 to 20 carbon atoms, and m represents an integer of 6 or greater.

9. The tire puncture sealing agent of claim 8 , wherein the nonionic surfactant is polyoxyethylene stearyl ether.

10. A tire puncture repair kit comprising the tire puncture sealing agent according to claim 8 .
