Abstract

A first object of the present invention is to provide a tire puncture sealing agent having excellent sealing property and injectability. A tire puncture sealing agent of a first embodiment of the present invention contains a particular amine compound, glycols, a rubber latex and/or a resin emulsion, and a surfactant. A second object of the present invention is to provide a tire puncture sealing agent having excellent retainability of generated foam and excellent sealing property even in a small liquid amount. A tire puncture sealing agent of a second embodiment of the present invention contains a particular polyether-modified silicone, glycols, a rubber latex and/or a resin emulsion, and a surfactant.

Claims (28)

1. A tire puncture sealing agent comprising an amine compound represented by General Formula (1), glycols, a rubber latex, and/or a resin emulsion, and a surfactant:

where, R 1 represents an alkylene group; R 2 represents a hydrogen atom, an alkyl group, or an alkyl group substituted with a hydroxy group or an amino group; and R 3 represents a hydrogen atom or an alkyl group,

wherein the glycols are a glycol ether represented by General Formula (2):

[Chemical Formula 3]

R 12 —O CH 2 CH 2 O p R 11   (2)

where, R 11 represents a hydrogen atom or an alkyl group; R 12 represents a methyl group;

and p represents an integer of 1 or greater.

2. The tire puncture sealing agent according to claim 1 , wherein a content of the amine compound is from 1 to 50 parts by mass per 100 parts by mass total 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 the General Formula (1), R 2 is an alkyl group.

4. A tire puncture sealing agent comprising a polyether-modified silicone represented by General Formula (1S), glycols, and a rubber latex and/or a resin emulsion, and a surfactant:

where, R 1 represents an alkylene group; R 2 represents a hydrogen atom or an alkyl group; n and m each independently represent an integer of 5 to 30; a and b each independently represent an integer of 1 to 10; a plurality of the R 1 moieties may be the same or different; and

a plurality of the R 2 moieties may be the same or different.

5. The tire puncture sealing agent according to claim 4 , wherein a content of the polyether-modified silicone is from 1 to 20 parts by mass per 100 parts by mass total of a solid content of the rubber latex and a solid content of the resin emulsion.

6. The tire puncture sealing agent according to claim 1 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.

7. The tire puncture sealing agent according to claim 2 , wherein, in the General Formula (1), R 2 is an alkyl group.

8. The tire puncture sealing agent according to claim 4 , wherein the glycols are a glycol ether represented by General Formula (2):

[Chemical Formula 6]

R 12 —O CH 2 CH 2 O p R 11   (2)

where, R 11 represents a hydrogen atom or an alkyl group; R 12 represents an alkyl group having from 1 to 5 carbons; and p represents an integer of 1 or greater.

9. The tire puncture sealing agent according to claim 5 , wherein the glycols are a glycol ether represented by General Formula (2):

[Chemical Formula 7]

R 12 —O CH 2 CH 2 O p R 11   (2)

where, R 11 represents a hydrogen atom or an alkyl group; R 12 represents an alkyl group having from 1 to 5 carbons; and p represents an integer of 1 or greater.

10. The tire puncture sealing agent according to claim 2 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.

11. The tire puncture sealing agent according to claim 3 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.

12. The tire puncture sealing agent according to claim 4 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.

13. The tire puncture sealing agent according to claim 5 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.

14. The tire puncture sealing agent according to claim 7 , wherein a content of the surfactant is from 1 to 20 parts by mass per 100 parts by mass total of the solid content of the rubber latex and the solid content of the resin emulsion.
