Tire sealant and tire repair kit
The object of the present invention is to provide a tire sealant and tire repair kit having excellent injectability. The present invention is a tire sealant containing a natural rubber latex, a synthetic resin emulsion, an anti-freezing agent, and at least one type of substance selected from the group consisting of a compound A represented by the following formula (1) and an anti-desiccant, a content of the substance being 0.3 to 10 mass %; and a tire repair kit using the same. In formula (1), R 1 is an amino group, a hydrogen atom, or a hydrocarbon group; and R 2 and R 3 are each independently a hydrocarbon group optionally comprising a heteroatom, or a hydrogen atom.
1. A tire sealant comprising:
a natural rubber latex;
a synthetic resin emulsion;
an anti-freezing agent; and
at least one type of substance selected from the group consisting of a compound A represented by the formula (1) and an anti-desiccant, a content of the substance being 0.3 to 10 mass %;
in formula (1), R 1 is an amino group, a hydrogen atom, or a hydrocarbon group; and R 2 and R 3 are each independently a hydrocarbon group optionally comprising a heteroatom, or a hydrogen atom.
2. The tire sealant according to claim 1 , wherein the synthetic resin emulsion is at least one type selected from the group consisting of an ethylene-vinyl acetate based copolymer emulsion, a vinyl acetate homopolymer emulsion, and a polysilicone emulsion.
3. The tire sealant according to claim 1 , wherein the anti-freezing agent is at least one type selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol and glycerin.
4. The tire sealant according to claim 1 , wherein the natural rubber latex has a solid content 1 that is from 25 to 95 mass % of the total of the solid content 1 and a solid content 2 of the synthetic resin emulsion.
5. The tire sealant according to claim 1 , further comprising a surfactant.
6. The tire sealant according to claim 1 , wherein the anti-desiccant is at least one type selected from the group consisting of a modified urea and a phenolic compound.
7. A tire repair kit comprising the tire sealant described in claim 1 and a compressor.
8. The tire sealant according to claim 2 , wherein the anti-freezing agent is at least one type selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol and glycerin.
9. The tire sealant according to claim 2 , wherein the natural rubber latex has a solid content 1 that is from 25 to 95 mass % of the total of the solid content 1 and a solid content 2 of the synthetic resin emulsion.
