Liquid coagulant and tire puncture sealing material set

Abstract

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 a natural rubber latex and/or a synthetic resin emulsion. The liquid coagulant contains a foaming agent capable of foaming the emulsion.

1 . A liquid coagulant for coagulating an emulsion containing a natural rubber latex and/or a synthetic resin emulsion,
 comprising a blowing agent for foaming the emulsion.   
     
     
         2 . The liquid coagulant according to  claim 1 , wherein said blowing agent is a reactive blowing agent using a urethane resin and/or an acrylic resin having two or more carboxy groups and a hydrogencarbonate salt. 
     
     
         3 . The liquid coagulant according to  claim 1 , wherein said blowing agent is a reactive blowing agent using a polyisocyanate compound. 
     
     
         4 . The liquid coagulant according to  claim 1 , wherein said synthetic resin emulsion is at least one selected from the group consisting of an ethylene vinyl acetate emulsion, an acrylic emulsion, and a urethane emulsion. 
     
     
         5 . The liquid coagulant according to  claim 1 , further comprising an antifreezing agent. 
     
     
         6 . The liquid coagulant according to  claim 5 , wherein said antifreezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, glycerin, methanol, ethanol, and isopropyl alcohol. 
     
     
         7 . The liquid coagulant according to  claim 1 , wherein said emulsion is a tire puncture sealant which further contains an antifreezing agent. 
     
     
         8 . The liquid coagulant according to  claim 7 , wherein said antifreezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, glycerin, methanol, ethanol, and isopropyl alcohol. 
     
     
         9 . 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 the liquid coagulant according to  claim 1 . 
     
     
         10 . The tire puncture sealant set according to  claim 9 , wherein said synthetic resin emulsion is at least one selected from the group consisting of an ethylene vinyl acetate emulsion, an acrylic emulsion, and a urethane emulsion. 
     
     
         11 . The tire puncture sealant set according to  claim 9 , wherein said antifreezing agent is at least one selected from the group consisting of ethylene glycol, propylene glycol, diethylene glycol, glycerin, methanol, ethanol, and isopropyl alcohol. 
     
     
         12 . 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 the liquid coagulant according to  claim 2 . 
     
     
         13 . 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 the liquid coagulant according to  claim 3 . 
     
     
         14 . 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 the liquid coagulant according to  claim 4 . 
     
     
         15 . 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 the liquid coagulant according to  claim 5 . 
     
     
         16 . 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 the liquid coagulant according to  claim 6 .
