Abstract
Official abstract text for this publication.
An object of the present invention is to provide a tire puncture sealant having excellent sealing performance and low-temperature properties. The tire puncture sealant of the present invention contains a natural rubber latex (A) and a vinyl versatate copolymer resin emulsion (B) as an emulsion of a vinyl versatate copolymer resin (b1) containing vinyl versatate as a monomer unit; the proportion of the vinyl versatate with respect to all monomer units constituting the vinyl versatate copolymer resin (b1) being from 30 to 70 mass %.
First claim
Opening claim text (preview).
1 . A tire puncture sealant containing a natural rubber latex (A) and a vinyl versatate copolymer resin emulsion (B) as an emulsion of a vinyl versatate copolymer resin (b1) containing vinyl versatate as a monomer unit; a proportion of the vinyl versatate with respect to all monomer units constituting the vinyl versatate copolymer resin (b1) being from 30 to 70 mass %. 2 . The tire puncture sealant according to claim 1 , wherein the vinyl versatate copolymer resin emulsion (B) described above contains an emulsifier (b2) containing polyvinyl alcohol; and a content of the emulsifier (b2) is from 0.8 to 3.0 mass % with respect to a solid content of the vinyl versatate copolymer resin emulsion (B). 3 . The tire puncture sealant according to claim 1 , wherein the vinyl versatate copolymer resin (b1) is an ethylene-vinyl acetate-vinyl versatate copolymer resin. 4 . The tire puncture sealant according to claim 1 , further containing a propylene glycol (C), wherein a mass ratio (B/C) of a solid content of the vinyl versatate copolymer resin emulsion (B) to the propylene glycol (C) is from 0.1 to 1.1. 5 . The tire puncture sealant according to claim 1 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 6 . The tire puncture sealant according to claim 2 , wherein the vinyl versatate copolymer resin (b1) is an ethylene-vinyl acetate-vinyl versatate copolymer resin. 7 . The tire puncture sealant according to claim 2 , further containing a propylene glycol (C), wherein a mass ratio (B/C) of a solid content of the vinyl versatate copolymer resin emulsion (B) to the propylene glycol (C) is from 0.1 to 1.1. 8 . The tire puncture sealant according to claim 2 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 9 . The tire puncture sealant according to claim 3 , further containing a propylene glycol (C), wherein a mass ratio (B/C) of a solid content of the vinyl versatate copolymer resin emulsion (B) to the propylene glycol (C) is from 0.1 to 1.1. 10 . The tire puncture sealant according to claim 3 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 11 . The tire puncture sealant according to claim 4 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 12 . The tire puncture sealant according to claim 6 , further containing a propylene glycol (C), wherein a mass ratio (B/C) of a solid content of the vinyl versatate copolymer resin emulsion (B) to the propylene glycol (C) is from 0.1 to 1.1. 13 . The tire puncture sealant according to claim 6 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 14 . The tire puncture sealant according to claim 7 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 15 . The tire puncture sealant according to claim 9 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60. 16 . The tire puncture sealant according to claim 12 , wherein a mass ratio (A/B) of a solid content of the natural rubber latex (A) and a solid content of the vinyl versatate copolymer resin emulsion (B) is from 90/10 to 40/60.
