Abstract
Official abstract text for this publication.
A puncture sealing agent is disclosed which comprises natural rubber latex, an aqueous solution of an adhesive and an antifreezing agent. The adhesive is a carbohydrate and the puncture sealing agent comprises a solid content resulting from the natural rubber latex in an amount of 21 wt % or less, based on the total weight of the puncture sealing agent.
First claim
Opening claim text (preview).
The invention claimed is: 1. A puncture sealing agent, comprising: natural rubber latex, an aqueous solution of an adhesive and an antifreezing agent, the adhesive being a carbohydrate, the puncture sealing agent comprising a solid content resulting from the natural rubber latex in an amount of 21 wt % or less, based on the total weight of the puncture sealing agent. 2. The puncture sealing agent according to claim 1 , wherein the solid content resulting from the natural rubber latex is 19 wt % or less, based on the total weight of the puncture sealing agent. 3. The puncture sealing agent according to claim 1 , wherein the solid content resulting from the natural rubber latex is 9 wt % or more, based on the total weight of the puncture sealing agent. 4. The puncture sealing agent according to claim 1 , wherein the puncture sealing agent comprises 30 wt % or more of the anti-freezing agent, based on the total weight of the puncture sealing agent. 5. The puncture sealing agent according to claim 1 , wherein the antifreezing agent is at least one selected from the group consisting of glycerol, propylene glycol, ethylene glycol and propane-1,3-diol. 6. The puncture sealing agent according to claim 1 , wherein the natural rubber latex, the aqueous solution of the adhesive and the antifreezing agent are natural components. 7. The puncture sealing agent according to claim 1 , wherein the combined content of all natural components of the puncture sealing agent is equal to or greater than 90 wt % based on the total mass of the puncture sealing agent. 8. The puncture sealing agent according to claim 1 , wherein the puncture sealing agent comprises 10 to 30 wt % of the aqueous solution of the adhesive, based on the total weight of the puncture sealing agent. 9. The puncture sealing agent according to claim 1 , wherein the amount of carbohydrate in the puncture sealing agent is 1.0 wt % or more, based on the total weight of the puncture sealing agent. 10. The puncture sealing agent according to claim 1 , wherein in the aqueous solution of the adhesive, the mass ratio (Z a :Z b ) of mass of dissolved carbohydrate (Z a ) to mass of solvent (Z b ) is in the range of from 90:10 to 50:50. 11. The puncture sealing agent according to claim 1 , wherein the puncture sealing agent comprises 9 to 19 wt % solid content derived from the natural rubber latex, 10 to 30 wt % of the aqueous solution of the adhesive and 30 wt % or more of the antifreezing agent, all based on the total weight of the puncture sealing agent. 12. The puncture sealing agent according to claim 1 , wherein the carbohydrate is at least one selected from the group consisting of sugars, starches, degraded starches and mixtures thereof. 13. The puncture sealing agent according to claim 1 , wherein the puncture sealing agent comprises a surfactant. 14. The puncture sealing agent according to claim 1 , wherein the solid content in the natural rubber latex is from 40 to 80 parts by mass, based on 100 parts by mass of the natural rubber latex. 15. A puncture repair system, comprising the puncture sealing agent according to claim 1 .
