A sealant composition is provided; the sealant composition comprises latex emulsion, nanoporous particles, surfactant, anti-freezing agent, wetting agent, and water. The sealant composition of the present application achieves a good sealing performance for the puncture of the tire. Furthermore, the sealant composition is easy to use and non-perishable, and has a long shelf life, which endows the sealant composition with a good market prospect.

Sealant composition

The present application relates to a sealant composition, comprising 80-95 wt % liquid carrier, 0.1-10 wt % gel material derived from a water soluble polymer, 1-10 wt % latex emulsion, 0.1-5 wt % rigid particles, and 0.1-5 wt % surfactant. The sealant composition can further comprise 0.1-1 wt % additives, such as anti-foaming agent, preservative, anti-corrosion additive, coloring agent and odorant, for corresponding functions. The present application also relates to a method of preparing the sealant composition.

Sealant composition and method of preparing the same

Valve-through tire puncture sealant compositions including dissolved and undissolved natural bio-materials, anti-freezing agents and other rigid particles are invented. In the preparation, an aqueous solution with 0.1-10 wt % dissolved bio-materials and 0.1%-10 wt % tackifier is mixed with anti-freezing agent, in which 0.01-5 wt % rigid particles of bio-materials and other particles are suspended. Weight percentage of water and anti-freezing agent are 20-40 wt % and 20-70 wt % respectively. Trace amounts of additives such as coloring and preservative are possibly added to the sealant. The invention includes the method for preparing the sealant composition containing bio-materials. The proposed sealant compositions have several advantages: Environmentally friendly, insignificant settling, long shelf-life, etc. The sealant is capable of sealing puncture formed by less than or equal to 6.35 mm spike for long duration, i.e. more than 30 hours.
