Tire puncture sealant, and tire puncture repair kit using same
View Patent ↗An object of the present invention is to provide a tire puncture sealant excellent in sealing performance even in a small amount. The present invention is a tire puncture sealant which contains a synthetic resin emulsion A, and a natural rubber latex and/or a synthetic resin emulsion B, in which the surface free energy of the synthetic resin emulsion A is from 20 to 50 mJ/m 2 , and the solid content of the synthetic resin emulsion A is from 5 to 25 parts by mass per 100 parts by mass of the solid content of the natural rubber latex and/or the solid content of the synthetic resin emulsion B, and a tire puncture repair kit using the same.
1. A tire puncture sealant comprising:
a synthetic resin emulsion A;
a natural rubber latex and/or a synthetic resin emulsion B, and
an antifreezing agent,
a surface free energy of the synthetic resin emulsion A being from 20 to 50 mJ/m 2 ,
a solid content of the synthetic resin emulsion A being from 5 to 25 parts by mass per 100 parts by mass of a solid content of the natural rubber latex and/or a solid content of the synthetic resin emulsion B.
2. The tire puncture sealant according to claim 1 , wherein the synthetic resin emulsion A is a silicone emulsion.
3. The tire puncture sealant according to claim 1 , wherein the synthetic resin emulsion B is an ethylene-vinyl acetate copolymer emulsion and/or a polyvinyl acetate emulsion.
4. The tire puncture sealant according to claim 1 , wherein the antifreezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol and glycerin.
5. The tire puncture sealant according to claim 1 , containing the natural rubber latex and the synthetic resin emulsion B, wherein the solid content of the natural rubber latex is from 20 to 85 parts by mass; and the solid content of the synthetic resin emulsion B is from 15 to 80 parts by mass based on a total of 100 parts by mass of the solid content of the natural rubber latex and the solid content of the synthetic resin emulsion B.
6. A tire puncture repair kit comprising the tire puncture sealant described in claim 1 .
