Abstract
An efficient tire sealant that is environmentally friendly or less damaging to the environment, which is characterized by a high stability, good processability, and safe application. The tire sealant includes approximately 5 wt. % to approximately 50 wt. % of a bio-based aliphatic diol; approximately 5 wt. % to approximately 70 wt. % natural rubber latex; and approximately 0.001 wt. % to approximately 10 wt. % of a water-soluble polymer as an additive for adjusting and/or influencing a freezing point of the tire sealant.
Claims21
A tire sealant, comprising:
- 5 wt. % to 50 wt. % of a bio-based aliphatic alcohol;
- 5 wt. % to 70 wt. % rubber latex;
- a water-soluble polymer, wherein the water-soluble polymer functions as an additive for adjusting and/or influencing a freezing point of the tire sealant, and wherein the tire sealant comprises less than 0.1 wt. % of the water-soluble polymer;
- and
- 0.001 wt. % to 5 wt. % of at least one surfactant, wherein the at least one surfactant is selected from polyoxyethylene alkyl ether, polyoxyethylene alkylamine, polyoxyethylene alkylamide, polyoxyethylene resin ester, fatty alcohol ethoxylate, and fatty alcohol polyglycol ether, and combinations thereof,
- wherein the tire sealant does not comprise an antioxidant.
A tire sealant, comprising:
- 5 wt. % to 50 wt. % of a bio-based aliphatic alcohol;
- 5 wt. % to 70 wt. % rubber latex;
- 0.001 wt. % to 0.08 wt. % of a water-soluble polymer as an additive for adjusting and/or influencing a freezing point of the tire sealant;
- and
- 0.1 wt. % to 5 wt. % of a bulking agent, wherein the bulking agent is selected from barium carbonate, titanium dioxide, calcium sulfate, aluminum oxide, and combinations thereof,
- wherein the tire sealant does not comprise an antioxidant.
A tire sealant comprising:
- 5 wt. % to 50 wt. % of a bio-based aliphatic alcohol;
- 5 wt. % to 70 wt. % rubber latex;
- 2 wt. % to 25 wt. % water, wherein the 2 wt. % to 25 wt. % of water does not include any water that is a component of the rubber latex;
- and
- 0.001 wt. % to 0.05 wt. % of a water-soluble polymer as an additive for adjusting and/or influencing a freezing point of the tire sealant;
- wherein the water-soluble polymer serving as an additive for adjusting and/or influencing the freezing point of the tire sealant is selected from a polyethylene glycol (PEG), a derivative thereof, polyvinylpyrrolidone (PVP), polyacrylic acid (PAA), a polyacrylamide, a polyoxazoline, a polyphosphate, polyglycerin, hydroxyethyl starch, a polyamide, a hydrophilic polysaccharide, a sucrose epichlorohydrin copolymer, and combinations thereof.
