Abstract

An object of the present invention is to provide a tire sealant and a tire repair kit that exhibit excellent injectability. Provided is a tire sealant including a natural rubber latex, a synthetic resin emulsion, an anti-freezing agent, a surfactant, and a chelating agent, wherein the content of the chelating agent is 0.1 mass % or greater.

Claims (18)

1. A tire sealant comprising:

a natural rubber latex;

a synthetic resin emulsion;

an anti-freezing agent;

a surfactant; and

a chelating agent, wherein

the chelating agent is an amino carboxylic acid-based compound, and a content of the chelating agent is 0.1 mass % or greater.

2. The tire sealant according to claim 1 , wherein the chelating agent is at least one selected from the group consisting of ethylenediamine tetraacetic acid, diethylenetriamine pentaacetic acid, and metal salts thereof.

3. The tire sealant according to claim 1 , wherein the synthetic resin emulsion is at least one selected from the group consisting of an ethylene-vinyl acetate copolymer emulsion, an ethylene-vinyl acetate-VeoVA copolymer emulsion, a vinyl acetate homopolymer emulsion, and a polysilicone emulsion.

4. The tire sealant according to claim 1 , wherein the anti-freezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, and glycerin.

5. The tire sealant according to claim 1 , wherein content 1 of solid content of the natural rubber latex is from 15 to 85 mass % of the total of the content 1 and content 2 of solid content of the synthetic resin emulsion.

6. A tire repair kit comprising the tire sealant described in claim 1 and a compressor.

7. The tire sealant according to claim 2 , wherein the synthetic resin emulsion is at least one selected from the group consisting of an ethylene-vinyl acetate copolymer emulsion, an ethylene-vinyl acetate-VeoVA copolymer emulsion, a vinyl acetate homopolymer emulsion, and a polysilicone emulsion.

8. The tire sealant according to claim 2 , wherein the anti-freezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, and glycerin.

9. The tire sealant according to claim 2 , wherein content 1 of solid content of the natural rubber latex is from 15 to 85 mass % of the total of the content 1 and content 2 of solid content of the synthetic resin emulsion.

10. The tire sealant according to claim 3 , wherein the anti-freezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, and glycerin.

11. The tire sealant according to claim 3 , wherein content 1 of solid content of the natural rubber latex is from 15 to 85 mass % of the total of the content 1 and content 2 of solid content of the synthetic resin emulsion.

12. The tire sealant according to claim 4 , wherein content 1 of solid content of the natural rubber latex is from 15 to 85 mass % of the total of the content 1 and content 2 of solid content of the synthetic resin emulsion.
