Liquid coagulant and tire puncture sealing material set
View Patent ↗Disclosed is a liquid coagulant which can be injected into the inside of a tire without the need of removing the tire from a rim and which can prevent the scattering of a residue of a tire puncture sealing material when the tire is removed from the rim. The liquid coagulant can coagulate an emulsion that contains natural rubber latex and/or a synthetic resin emulsion. The liquid coagulant contains a foaming agent capable of foaming the emulsion. Also disclosed is a tire puncture sealant set including the coagulant and a method of coagulating a tire puncture sealant.
1. A tire puncture sealant set, comprising:
a tire puncture sealant which contains a natural rubber latex,
a synthetic resin emulsion, and
an antifreezing agent; and
a liquid coagulant for coagulating the tire puncture sealant,
wherein the liquid coagulant includes a blowing agent for foaming the tire puncture sealant, and the blowing agent is one of a reactive blowing agent using a urethane resin and/or an acrylic resin having two or more carboxy groups and a hydrogencarbonate salt; and a reactive blowing agent using a polyisocyanate compound.
2. The tire puncture sealant set according to claim 1 , wherein the synthetic resin emulsion is at least one of an ethylene vinyl acetate emulsion, an acrylic emulsion, and a urethane emulsion.
3. The tire puncture sealant set according to claim 1 , wherein the antifreezing agent is at least one of ethylene glycol, propylene glycol, diethylene glycol, glycerin, methanol, ethanol, and isopropyl alcohol.
4. The tire puncture sealant set according to claim 1 , wherein the liquid coagulant further comprises an antifreezing agent.
5. The tire puncture sealant set according to claim 4 , wherein the antifreezing agent is at least one of ethylene glycol, propylene glycol, diethylene glycol, glycerin, methanol, ethanol, and isopropyl alcohol.
6. A method of coagulating a tire puncture sealant remaining in a pneumatic tire, comprising the step of:
injecting a liquid coagulant into a punctured tire, in which the tire puncture sealant is remaining, without removing the tire from a rim,
wherein the tire puncture sealant includes a natural rubber latex, a synthetic resin emulsion and an antifreezing agent,
wherein the liquid coagulant includes a blowing agent for foaming the tire puncture sealant, and the blowing agent is one of a reactive blowing agent using a urethane resin and/or an acrylic resin having two or more carboxy groups and a hydrogencarbonate salt; and a reactive blowing agent using a polyisocyanate compound, and
wherein the blowing agent causes in-situ coagulation of the tire puncture sealant, leaving no liquid components in the tire.
