Abstract: 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.

Abstract: 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.

Abstract: A tire repair device comprises a bottle body for containing tire sealant and a bottle cap deposited at an opening of the bottle body to seal the bottle body; wherein the tire repair device further comprises a tire sealant guiding tube provided in the bottle cap, and the tire sealant guiding tube includes a first tube section extending into the bottle body and a second tube section; a flange is formed on an internal surface of the first tube section; a plug is slidably placed in the first tube section; at least one rib is fixed in the first tube section and is deposited between the flange and the first bottom end. The tire repair device of the present application has a simple structure, is easy to operate, and is cost-effective; besides, the tire repair device can be used either upright or upside-down, which is good for promotion and implementation.

Abstract: 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.

Abstract: The present invention discloses a tire sealant and a preparation method thereof. The tire sealant comprises a solvent of 35%-95%, PVA gel of 0.05%-10%, block particles of 0.01%-5% and an additive of 0.1%-10%. The tire sealant can also comprise chitosan gel of 0.01%-5%. The method comprises the following steps: S1. polymer material particles are dissolved and precipitation is controlled to form suspended gel material in a liquid medium; S2. An additive is added into the liquid medium; and S3. block particles are added into the liquid medium containing the suspended gel material. When using the tire sealant and its preparation method in the present invention, the puncture formed by a spike with a diameter equal to or less than 6.35 mm can be sealed. Besides, the broken hole can be repaired between ?40? and 70?, and the sealing time can last for more than 48 hours.

Abstract: A tire repair device comprises: a bottle body 10 containing tire cement, and a bottle cap 20 formed at an opening of the bottle body 10. A tire cement guiding tube is provided in the bottle cap 20, in which the guiding tube includes a first tube section 21 axially parallel to the bottle body 10 and a second tube section 22 perpendicular to the first section 21 of the tube. The second tube section 22 connects with an end of a fluid transfer tube 30, and a connector 40 is formed at the other end of the fluid transfer tube 30, and the connector is connected to a tire to deliver tire cement from the bottle body 10 to damaged areas of the tire. A step 25 is formed along the inside wall between an entrance 211 of the first tube section 21 and an entrance 221 of the second tube section 22.
