Abstract

An object of the present invention is to provide a coagulant with excellent coagulability performance, and a tire puncture repair kit that uses the coagulant. The present invention is a coagulant of a tire puncture repair liquid, the coagulant including at least one component selected from the group consisting of a plant protein, a pectin, a cellulose, a phospholipid and a fatty acid glyceride, and a tire puncture repair kit that uses the coagulant.

First claim

The invention claimed is:

1. A coagulant of a tire puncture repair liquid, the coagulant comprising at least one component selected from the group consisting of a plant protein, a pectin, a cellulose, a phospholipid and a fatty acid glyceride, a quantity of the components per 100 parts by mass of the tire puncture repair liquid being 16 parts by mass or more, and
at least one metal salt selected from the group consisting of aluminum sulfate, calcium chloride, magnesium chloride and sodium chloride.

2. A coagulant of a tire puncture repair liquid, the coagulant comprising:
a plant protein;
a pectin;
a cellulose; and
a fatty acid glyceride,
a mass ratio of the plant protein:the pectin:the cellulose:the fatty acid glyceride being 10 to 25:30 to 50:25 to 35:5 to 15, and
a total quantity of the plant protein, the pectin, the cellulose and the fatty acid glyceride per 100 parts by mass of the tire puncture repair liquid being 8 parts by mass or more.

3. The coagulant according to claim 2 , further comprising a phospholipid.

4. The coagulant according to claim 1 , wherein the fatty acid glyceride is a fatty acid triglyceride.

5. The coagulant according to claim 1 , wherein a quantity of the metal salt is 5 to 20 mass % of the total quantity of the coagulant.

6. The coagulant according to claim 1 , wherein the tire puncture repair liquid contains at least one selected from the group consisting of a natural rubber latex and an ethylene-vinyl acetate copolymer emulsion, and an anti-freezing agent.

7. The coagulant according to claim 6 , wherein the anti-freezing agent is at least one substance selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol and glycerin.

8. A tire puncture repair kit comprising:
a tire puncture repair liquid; and
the coagulant descried in claim 1 .

9. The coagulant according to claim 2 , wherein the fatty acid glyceride is a fatty acid triglyceride.

10. The coagulant according to claim 2 , further comprising at least one metal salt selected from the group consisting of aluminum sulfate, calcium chloride, magnesium chloride and sodium chloride.

11. The coagulant according to claim 10 , wherein a quantity of the metal salt is 5 to 20 mass % of the total quantity of the coagulant.

12. The coagulant according to claim 2 , wherein the tire puncture repair liquid contains at least one selected from the group consisting of a natural rubber latex and an ethylene-vinyl acetate copolymer emulsion, and an anti-freezing agent.

13. The coagulant according to claim 12 , wherein the anti-freezing agent is at least one substance selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol and glycerin.

14. A tire puncture repair kit comprising:
a tire puncture repair liquid; and
the coagulant described in claim 2 .
