AI Technical Summary

Problems solved by technology

[0013] (3) Latex must not be allowed to enter sewage / surface water or groundwater;
[0014] (4) Any used packaging contaminated with cured latex cannot be cleaned for reuse and must therefore be disposed of along with the substance
[0015] (5) Cleaning and washing of tires is problematic with latex; tires can only be cleaned by blotting up the liquid with a cloth / rag, then place the cloth in a waste disposal container
[0016] (6) Latex emulsion releases strong ammonia vapor, so it is not popular in tire repair shops etc. due to harmful smell
[0021] In addition to the problems with the prior art described above, it is currently a trend in vehicle design that vehicles are manufactured and sold without a spare wheel

Embodiment 1

[0168] The sealant composition of the present invention comprises a suitable elastomer, more specifically sodium polyacrylate, in suspension. Sodium polyacrylate in particulate form will pass through tire valves in this suspension without clogging.

[0169] This composition was prepared in two parts, hereinafter respectively referred to as premixed rosin solution (A) and granule solution (B), which were then mixed as explained below.

[0170] Premixed rosin solution (A) includes the following items (content is given in weight percent):

[0171] (1) Ethylene glycol-18;

[0172] (2) Propylene glycol-24;

[0173] (3) Water -15.8;

[0174] (4) ammonia water 20%-4.0;

[0175] (5) Ethanol-4.0;

[0176] (6) Formalin-0.2;

[0177] (7) Propylene Glycol-24.0 and

[0178] (8) Rosin - 10.0.

[0179] Solution (A) was formed as described below.

[0180] Components (1) to (6) are first mixed under stirring, preferably in descending order. Rosin (7) was added separately to the remai...

Embodiment 2

[0196] Another preferred embodiment relates to a method for the preparation of a composition for sealing punctures and pneumatic tires, said method comprising the steps of:

[0197]A. Form the hot phase premix by adding rosin (1.5% by weight of the final composition) and propylene glycol (1.5% by weight of the final composition) to a steam jacketed vessel and heating to a temperature of about 100°C Until the rosin is completely melted in propylene glycol, then cooled under stirring until a temperature of about 50°C is reached, then ethylene glycol (1.0% by weight of the final composition), 20% ammonia water (1.0% by weight of the final composition), 0.4% by weight), water (0.7% by weight of the final composition), polyethylene powder (10 μm to 180 μm in size) (1.0% by weight of the final composition), diatomaceous earth (0.8% by weight of the final composition ) and zinc stearate (accounting for 0.2% by weight of the final composition);

[0198] B. Form the gel phase premix i...

Embodiment 3

[0204] A composition for sealing a punctured vehicle tire, said composition comprising the following ingredients (all amounts are by weight percent of the final composition):

[0205] (1) Propylene glycol 81.0

[0206] (2) Glycerin 1.0

[0207] (3) Xanthan gum 0.11

[0208] (4) flax husk powder 0.012

[0209] (5) Carboxymethyl cellulose 0.03

[0210] (6) Diatomaceous earth 0.25

[0211] (7) Gum resin powder 1.35

[0212] (8) Magnesium carbonate 0.135

[0213] (9) Rice bran powder 0.3

[0214] (10) Titanium dioxide 0.075

[0215] (11) Cork powder 0.15

[0216] (12) Bark powder (dry) 0.1

[0217] (13) Asking powder 0.1

[0218] (14) Polyethylene powder 0.2

[0219] (15) Water 13.176

[0220] (16) Sodium bicarbonate 0.05

[0221] (17) Ammonium carbonate 0.05

[0222] (18) Sodium borate 1.0

[0223] (19) Formalin 0.2

[0224] (20) Fluorescein 0.012, and

[0225] (21) One or more polyacrylates in an amount of 0.05 to 2.0% by weight.

Abstract

A sealant composition for the sealing of a punctured tyre including a liquid carrier, one or more viscosity and suspending agents, one or more fillers and sealants, and one or more polyacrylates.

Description

field of invention [0001] The present invention relates generally to improved compositions for sealing (by repairing) damaged inflatable articles. More particularly, but not exclusively, the present invention relates to improved compositions for sealing (by repairing) damaged, eg punctured automobile tires. The invention also relates to methods of preparing such compositions. Background of the invention [0002] The present invention relates to improvements or modifications to sealant compositions which are the subject of the Applicant's International Application (PCT) PCT / AU2007 / 001222. [0003] Punctures can be a serious hazard in the use of pneumatic load bearing articles such as tires - whether car tires, truck tires, motorcycle tires, bicycle tires, etc. of any kind. When a car has a puncture, such as the traditional practice of replacing a damaged / punctured tire with a spare tire, this spare tire is intended to allow the vehicle to be used for a limited time and for ...
