2. The puncture repair material gelling agent according to claim 1 , wherein the antifreezing agent (β) is at least one type selected from the group consisting of propylene glycol, diethylene glycol, and glycerin.

3. The puncture repair material gelling agent according to claim 1 , wherein the puncture repair material gelling agent is a liquid at 20° C. and gels the puncture repair material (D) at 20° C. within 10 minutes.

4. The puncture repair material gelling agent according to claim 1 , wherein the puncture repair material gelling agent is a liquid at −20° C. and gels the puncture repair material (D) at −20° C. within 20 minutes.

5. The puncture repair material gelling agent according to claim 2 , wherein the puncture repair material gelling agent is a liquid at 20° C. and gels the puncture repair material (D) at 20° C. within 10 minutes.

6. The puncture repair material gelling agent according to claim 3 , wherein the puncture repair material gelling agent is a liquid at −20° C. and gels the puncture repair material (D) at −20° C. within 20 minutes.

7. The puncture repair material gelling agent according to claim 1 , further comprising up to 50 mass % of a solvent additive.

8. The puncture repair material gelling agent according to claim 7 , wherein the solvent additive comprises water.

9. A puncture repair material gelling agent comprising a compound (α) of formula (1) and an antifreezing agent (β), said puncture repair material gelling agent comprising 50 mass % or more of the compound (α):

wherein R 1 is an alkyl group having from 13 to 30 carbon atoms or an alkenyl group having from 13 to 30 carbon atoms.

10. A puncture repair material gelling agent comprising a compound (α) of formula (1) and an antifreezing agent (β), said puncture repair material gelling agent comprising from 3 to 5 parts by mass of the antifreezing agent (β) per 10 parts by mass of the compound (α):

wherein R 1 is an alkyl group having from 13 to 30 carbon atoms or an alkenyl group having from 13 to 30 carbon atoms.

11. A puncture repair kit comprising: a puncture repair material (D) comprising a natural rubber latex (A), a resin emulsion (B), and an antifreezing agent (C), wherein a solid content of the natural rubber latex (A) is 30 mass % or more of a total of a rubber solid content and a resin solid content of the puncture repair material (D); and a puncture repair material gelling agent according to claim 1 .

12. A puncture repair kit comprising: a puncture repair material (D) comprising a natural rubber latex (A), a resin emulsion (B), and an antifreezing agent (C), wherein a solid content of the natural rubber latex (A) is 30 mass % or more of a total of a rubber solid content and a resin solid content of the puncture repair material (D); and a puncture repair material gelling agent according to claim 9 .

13. A puncture repair kit comprising: a puncture repair material (D) comprising a natural rubber latex (A), a resin emulsion (B), and an antifreezing agent (C), wherein a solid content of the natural rubber latex (A) is 30 mass % or more of a total of a rubber solid content and a resin solid content of the puncture repair material (D); and a puncture repair material gelling agent according to claim 10 .

14. A method of use for the puncture repair material gelling agent according to claim 1 , comprising:

introducing the puncture repair material gelling agent according to claim 1 into a pneumatic tire assembled on a rim that has undergone puncture repair by having a puncture repair material (D) comprising a natural rubber latex (A), a resin emulsion (B), and the antifreezing agent (C), wherein a solid content of the natural rubber latex (A) is 30 mass % or more of a total of a rubber solid content and a resin solid content of the puncture repair material (D) introduced into the tire;

mixing the puncture repair material (D) and the puncture repair material gelling agent; and
