Description

 The subject of the invention is a liquid product or a colloidal gel for maintenance and closure for the puncture holes in pneumatic tires and the process for obtaining them.

 The invention applies in particular to tires for motor vehicles, velocipeds, motorcycles and trucks, as well as utility vehicles with civil or military applications.

 The product placed by injection into a tire filled with air, using a pump and through the valve or by the sidewall, makes it possible to eliminate the loss of air by porosity of the gum, to eliminate rust and repair by puncturing punctures up to a certain diameter (holes, tears, bullets). This product also allows the self-balancing of the tire by creating a kinetic flywheel and the fight against overheating by creating a thermal bridge making it possible to evacuate the calories from the tread, via the sidewall, towards the radial area. It retreads the tire from the inside by saturating the internal layers, which, as they age, bakelize with the creation of micro-cracks, which allows internal smoothing. It follows that the tires, thus treated, consume less gum and that vehicles, thus equipped, consume less energy (diesel, petrol, ...). The wear is then regular.

The state of the art can be defined by two types of products
- healing healing bombs, and
- preventive maintenance products.

 Repair bombs are not made to prevent the tire from deflating or puncturing, but their purpose is to reuse the tire, and this, provisionally, to reach the nearest service station. There is therefore no prevention, but simply a temporary remedy.

 The documents FR-A-2,581,935 and FR-A-2,571,312 describe vulcanizing product devices for the repair of tires, bicycles, motorcycles and cars and trucks.

 Current maintenance products, which act as a preventive measure, have had little success. These products are not technically perfect. Thus, these maintenance products, because of their poor composition, cause damage to the tire, in particular with regard to the development of rust and cause vibrations.

 These products do not retain their properties well. Over time, the composition does not remain homogeneous and the products separate.

When this separation of the components occurs, the composition is no longer homogeneous, and thereby becomes ineffective in repairing and plugging up any loss of air. In addition, these products, the composition of which is not stable over time, form balls which cause vibrations in the wheels by unbalancing them. All these drawbacks explain why current products have not been successful.

 Other products use, in their organic composition, mainly long asbestos fibers which tend to fluff, which makes the product ineffective, and which are dangerous for health.

 Document FR-A-2,433,552 relates to a lubricating composition intended to be applied inside a tire which comprises a polybutene, a gelling agent such as an acrylic polymer or a polyethylene, as well as a solid material in particles, such as untreated rubber crumbs or sawdust, for sealing punctures.

 Document US-A-4,045,362 proposes a composition which includes anti-freeze, antioxidant and thickening agents.

 However, these compositions and especially that of the American document have the effect of greatly reducing the degree of friction on the internal walls of a tire during under-inflation or deflation.

 The possible possibility of a hole plugging on the pneumatic envelope is only vaguely cited, without explanation and without example.

 It should also be noted that certain compounds used in the manufacture of these products constitute a big difference with the present invention. Thus, there is use of short fibers, lubricating products such as polyethylene oxide and a wetting agent.

 The documents FR-A-2,633,556 and FR-A-2,642,698 relate to a liquid maintenance and sealing product for puncture holes in pneumatic tires and the process for obtaining them. This product has a more effective composition. This composition does not flock, for example certain products using, as sealing agent, long fibers. This composition does not contain any corrosive solvent towards the tire. However, the results are not perfectly conclusive, the product introduced into the punctured tire only works for tire pressures between 2.2 to 2.5 kg and for holes up to 6 mm. This formulation is only suitable for small utility vehicles.

 Most often, the other current products do not give satisfaction to the extreme temperatures of between -50 ° C. and + 140 ° C. to which the tires are subjected, which is not the case for the product according to the invention.

 Often the typical conditions of use of the tires cause the healing substances to flow and are driven out through the hole left by a puncturing object, for current products. The product according to the invention is not driven outside the hole.

 The current sealing compositions are too weak and when a nail penetrates into the tire, the point of the nail lifts the layer of product; the cellulose fibers create a ball around the nail, which normally should come off over time. The layer can also break, which makes current products ineffective in both cases.

 The state of the art makes it possible to highlight the advantage of these products for sealing the holes for punctures in pneumatic tires.

 Among the large number of patents describing compositions which plug the hole by vulcanization, the following patents can thus be cited: 2,451,279, 2,455.993, 2,455.994, 2,455.995, 2,431,379, 2,433,380, 2,489,347 and 2,495,335.

 Other patents describe the use of a mechanical barrier placed in or inside the tire.

This barrier acts as a shield.

 Some products are used in aerosol cans.

 Document FR-A-2,256,047 describes a product which uses a latex, a polybutene emulsion, a surfactant and an antifreeze.

 Other patents such as FR-2,356,530 and especially FR2,297,146 use swelling products, asbestos fibers, ethylene glycol, an anti-rust agent and a thickening agent. According to another embodiment, the composition uses glass fibers, in particular for large tires.

 The patents FR-2,399,923 and FR-2,399,924 describe a product for sealing puncture holes containing a lubricant consisting of a polybutene, it contains a surfactant which facilitates the elimination of said product for sealing the tire by use water in a subsequent retreading treatment of the tire.

 The present invention solves all of the above problems.

 To this end, the invention provides a maintenance and sealing product for puncture holes in pneumatic tires of the type consisting essentially of demineralized water, a sealing agent such as particles of rubber and / or cellulose. , a colloidal coating agent, such as aluminum and magnesium silicate, a thickening agent such as xanthan, an organic solvent which allows the expansion of the sealing agent and a anti-freeze such as monoethylene glycol, characterized in that the organic solvent is a mixture of toluene and / or xylene and terpene (s).

 This product includes an anti-rust such as sodium nitrate, a catalyst such as sodium hydroxide and / or a bactericide such as Parmetol (registered trademark).

 The composition of the product in percentage by weight is 50 to 60% of demineralized water, 3 to 5% of sealing agent, 1 to 1.5% of colloidal coating agent, 0.1 to 0.5% thickening agent, 1 to 5% organic solvent and 30 to 40% anti-freeze.

 The sealing agent is formed as a weight percentage of 30 to 50% of rubber particles, and 50 to 80% of cellulose particles.

 The organic solvent is formed as a percentage by weight of 60 to 80% of toluene and / or xylene and 20 to 40% of terpene (s).

 The composition of the product comprises additives in percentage by weight in the proportion of 0.1 to 0.5% of rust inhibitor, 0.5 to 2% of catalyst and 0.1 to 0.5% of bactericide.

 The composition of the product in percentage by weight contains from 1 to 10% of outstanding products, such as methylene blue or eosin, having healing, antiseptic and reagent functions.

 According to a first embodiment, the rubber particles have a particle size between 0 and 0.8 mm for puncture holes up to 8 mm, for pneumatic pressures up to 4 kg / cm3 and for speeds below 120 km / h applied to light four-wheeled vehicles, so that the vehicles are not imbalanced, vibrated or shimmy.

 According to a second embodiment, the rubber particles have a particle size between 0 and 0.8 mm for puncture holes up to 6 mm for pneumatic pressures up to 3.5 kg / cm3 and for lower speeds at 130 km / h applied to light vehicles of the two-wheel type.

 According to a third embodiment, the rubber particles have a particle size between 0 and 1.2 mm for all puncture holes up to 8 mm for pneumatic pressures up to 4.5 kg / cm3 for lower speeds at 130 km / h applied to light four-wheeled vehicles of the utility or passenger type.

 According to a fourth embodiment, the rubber particles have a particle size between 0 and 1.8 mm for all puncture holes up to 12 mm, for pneumatic pressures up to 8 kg / cm3 and for lower speeds at 130 km / h applied to very heavy vehicles or public works machinery.

 The cellulose particles added to the rubber particles consist of 50% of particles from 1 to 5 mm on a side, and 50% of strips of 1 to 2 mm by 40 to 80 mm, for puncture holes up to 50 mm and for pneumatic pressures up to 10 kg / cm3 applied to special heavy vehicles such as civil engineering vehicles, armored military vehicles.

 The significant products are expelled as soon as a new puncture appears, so that if this puncture is the result of a voluntary human act, the offender is marked by coloring. A neutralizing gas can optionally be added.

The process for manufacturing the product, the technical characteristics of which have just been listed, consists in mixing the rubber particles with part of the solvent in a hermetically sealed container, leaving the whole to stand for several days, and stirring the content at regular time intervals.This process is characterized in that it consists
- pour demineralized water into three vitrified steel containers,
- to be added to the first container, while stirring at a constant speed the demineralized water therein, the catalyst and then the anti-rust,
- add to the second container, while stirring at increasing speed and after heating to a temperature between 50 and 85 degrees Celsius ('C) of the demineralized water therein, the thickening agent, up to homogeneity of the solution,
- to be added to the third container, while stirring at a constant speed the demineralized water therein, the colloidal coating agent,
- to be charged in a decanter with demineralized water which is agitated, while the content of the first container is added, then the bactericide, the antifreeze, the cellulose and the part of terpene (s) not yet used,
- to start the circulation pump,
- reduce agitation in the second container and put the second and third containers under nitrogen,
- to transfer half of the third container to the decanter and the other half to the second container,
- transfer the contents of the second container to the decanter, first under pressure and then by gravity,
- to add the expanded rubber and the solvent used for this expansion,
- to stop the circulation pump, and
- shake everything for several hours.

 Terpenes are used in a proportion of 40 to 80% for decantation and 20 to 60% for the expansion of rubber particles.

 The solution of demineralized water, of the catalyst and of the anti-rust, contained in the first container, receives an amount of acid such as hydrochloric acid, in order to obtain a neutral hydrogen potential (pH).

 Demineralized water is used initially in an amount of approximately 3 to 6% in the first container, 18 to 22% in the second container, 18 to 32 * in the third container, and 35 to 48 * in the decanter.

 The significant products are added at the end of the process after the addition of expanded rubber and solvent and before stopping the circulation pump.

 The explanations below are given by way of indicative and nonlimiting examples. They illustrate preferred embodiments of the present invention. They will allow the invention to be easily understood.

 The main object of the present invention is to offer the widest possible range of repair possibilities for punctures applied to pneumatic tires. Thus and contrary to the state of the art, it is possible to treat tires exceeding pressures of 2.5 kg to go up to 10 kg of pressure and to heal holes greater than 6 mm up to 50 mm.

 To do this, it was necessary to distinguish from patent application FR-A-2,642,698 by formulations which are different.

In addition, the process for obtaining such products is also different. Even if this maintenance and sealing product for puncture holes in pneumatic tires is of the same type as that of the patent cited above, that is to say that it contains demineralized water, an agent for clogging, a colloidal coating agent, a thickening agent, an organic agent, an anti-freeze, it is characterized by the presence of an organic solvent derived from a mixture of toluene and / or xylene and terpene (s) .

 As was the case with this prior art document, the sealing agent was composed either of rubber particles, or of cellulose particles, or of a set of rubber and cellulose particles.

 The colloidal coating agent such as aluminum magnesium silicate can be used. The thickening agent consists of xanthan. The organic solvent is used to allow the extension of the sealing agent. Finally, an anti-freeze such as monoethylene glycol is used.

 The essential innovation of the present invention therefore consists in the nature of the organic solvent which is a mixture of toluene and / or xylene and terpene (s).

 Nevertheless, with all of these products, it is possible to combine an anti-rust agent such as sodium nitrate, a catalyst such as sodium hydroxide and / or a bactericide such as Parmetol.

 Whatever the embodiment of the product, the composition of the latter in weight percentage is substantially from 53 to 558 demineralized water, 3.5 to 4.5 sealing agent, 1 to 1.5% of colloidal coating agent, approximately 0.53% of thickening agent, 1.5 to 3% of organic solvent and 35 to 37% of antifreeze.

 In fact, the sealing agent is formed, in the preferred embodiment of the product, from 30 to 50% of rubber particles and from 50 to 80% of cellulose particles. For its part, the solvent is formed from 70 to 80% by weight percentage of toluene and / or xylene, the remainder consisting of terpenes.

 Finally, all of the additives are of a small percentage.

 There is approximately 0.3 anti-rust, 1% catalyst and 0.15% bactericides.

 According to a particular embodiment, the product contains 2% of outstanding products such as methylene blue or eosin, having functions of healing, antiseptic and reagent.

These products make it possible, on the one hand to facilitate the sealing of the puncture holes and to fight against bacteria, and on the other hand, to crosslink the particles of the formulation at the level of the puncture hole or the notch.

The product preparation mode uses an apparatus which consists, without limitation or limitation, of a G21W reactor of 370 liters of vitrified steel capacity, in which stirring at fixed speed of impeller type with counter blade at a speed of 130 revolutions per minute (rpm), can be achieved using a heating and cooling device that can vary the temperature within it between -25'C and +180 C. There is also a G23W reactor of 160 liters capacity, also in vitrified steel, whose agitation is variable and is carried out using an anchor with counter-blade, the speed can vary from 20 to 115 rpm . I1 has a dip tube and a heating / cooling device for temperatures identical to those of the G21W reactor. The third reactor is of the Buchi type; it is a CR25K model with a capacity of 25 liters in vitrified steel with variable impeller agitation, the agitation speed of which is between
0 and 600 rpm with a heating / cooling means identical to the previous ones.

 There is also a T2W decanter with a capacity of 1500 liters in stainless steel with variable agitation, which is equipped with an external circulation pump with filling gun.

 In addition, there is a 200 liter Röhn wheel, an air pump, a ph meter and a scale.

 In a first procedure, the first day, put in the 200-liter Röhn wheel, seventy-two hours before obtaining the final product, the rubber powder in an amount of 18.5 kg in fine particles, then add terpenes, ie 3 kg and finally toluene and / or xylene for a total of 15.7 kg; we close, we set in motion, the seal must be checked. The duration of this operation is one to two hours. Once this operation is completed, the movement is stopped while leaving the wheel closed, the opening of the wheel being directed upwards. On the second day, the Rohn wheel is set in motion two or three times for a period of one to two hours.

On the third day, this wheel is set in motion two or three times also for a period of one to two hours.

 The operation during these first three days consists in bringing together the rubber particles and the solvent, which will allow the rubber to expand.

 On the fourth day, in the 25-liter Buchi reactor, distilled water is added in the proportion of 33 kg for a temperature of 15 to 20 ° C. Agitation is started at a speed of 300 rpm. Sodium hydroxide pearl is added for an amount of 0.36 kg, then sodium nitrite for 3.5 kg whose temperature is 15 to 20 ° C and for a period of about 10 minutes.

 Using the pH meter, the value of the hydrogen potential is currently adjusted from 10 to 11. This adjustment is made using hydrochloric acid at 32 *, the amount of which will vary according to the amount to add to reach a pH of about 7. It is also possible to add hydrochloric acid to about 10% which has been diluted with demineralized water. Anyway, it is necessary that the pH be stabilized between 7 and 7.5; the duration of this operation is approximately one hour.

 In the G23W reactor, the double jacket of which is connected to the steam circuit, demineralized water is placed for an amount of 135 kg at 15 or 20 ° C., which is stirred at a speed of 60 rpm , then the mixture is heated for approximately 35 minutes at a temperature between 50 and 85 C. The stirring is then increased to a speed of 100 rpm and the heating is switched off to allow the addition of xanthan in the rain, the amount is 3.8 kg at the previous temperature; this is done in 5 minutes. Then, the stirring speed is further increased until the maximum is reached, ie between 80 and 120 rpm. This stirring is carried out until homogenization at a temperature of 60-70 C, the duration of this operation must be one hour.

Simultaneously with this operation, the reactor is carried out
G21W, a mixture between, on the one hand, 200 kg of demineralized water put in agitation and, on the other hand, a colloidal topping agent, whose mass is 14 kg, this topping agent is loaded with rain. The duration of this operation is 5 minutes and the temperature of the two components, that is to say demineralized water and colloidal coating agent, is from 15 to 20 ° C. Then, it is stirred for about an hour, always at this same temperature until homogeneous. During the hour of preparation of the homogeneous gels of xanthan and colloidal topping agent, distilled water for 290 kg is loaded into the stainless steel decanter, still at a temperature of 15 to 20 ° C., it is started up stirring at minimum speed. Then, using an air pump, add the contents of the Buchi container, the pH of which is always 7 to 7.5, this operation is carried out in approximately 5 minutes. Then, 1.75 kg of Parmetol is added, the monoethylene glycol, the quantity of which is 440 kg, is then loaded with the air pump at a temperature of 15 to 25 ° C .; the duration of this operation is 15 to 20 minutes. One agitates strongly while starting the pump of outside circulation. Then, 40 kg of cellulose are added over the course of 5 to 15 minutes; the stirring is then continued until a homogeneous medium with a temperature of 23 ° C. is obtained. The remaining terpenes are then loaded, ie 4.4 kg, an operation which is carried out very quickly. Then, the G23W reactor should be placed under nitrogen, the pressure being equal to 1 bar and the temperature at around 60 ° C. Then, the content, that is to say the xanthan gel, is transferred to the decanter which is cooled with water. Its temperature is then 23 to 36 C, this temperature being reached between 5 and 10 minutes. Then, stir the homogeneous white gel which arises in the decanter
D2W whose temperature is 33-36 ° C after a period of 10 minutes. The G21W reactor is then placed under nitrogen at a pressure of 1 bar for a temperature of 15 to 20 ° C. Half of its content, which contains gel, is then transferred to a light brown colloidal coating agent in the G23W reactor in order to remove traces of xanthan. This operation under nitrogen pressure allows the transfer of agent of colloidal coating contained in the G23W reactor up to the D2W decanter.

 This operation is then repeated with the other half of the colloidal coating agent gel remaining in the G21W reactor; this operation takes place between 10 and 15 minutes.

 Now the D2W decanter has a mass at 30-33 ° C which is agitated. The rubber powder which has been treated, ie 37.2 kg of fine particles, is then added. These particles come from the preparation of the first day and are composed, for the record, of terpenes in the proportion of 3 kg, of rubber powder for 18.5 kg in the form of fine particles and of toluene and / or xylene for 15, 7 kg; the duration of this operation is 10 to 15 minutes.

 This mixture is stirred for an hour and a half, then the outdoor circulation pump is stopped, then stirred for 2 to 3 hours. The production takes place overnight, the temperature is then between 17 and 40 C. On the fifth day, the agitation and the external circulation pump are restarted. It is thus stirred for one hour at a temperature of 20 to 30 ° C.

 Then, all that remains is to unload the product obtained in plastic drums. The total mass of product thus obtained is theoretically 1182.14 kg.

 In a very conventional manner, the preparation ends with a cleaning of the reactors G21W, G23W and of the settling tank D2W and finally of the air pump.

 However, depending on the nature of the vehicles for which the product should be used, there are three types of rubber powder, taking into account the particle size. For the finest particles, the particle size does not exceed 0.4 mm; in this case, the puncture holes may not exceed 8 mm and the pneumatic pressures may not exceed 4 kg / cm3. The maximum speeds achieved by vehicles so equipped will not exceed 120 km / h. Such very fine particles can be applied to light vehicles with four wheels, so that the vehicles no longer suffer from imbalance, vibrations and shimmy.The rubber particles can have an identical particle size for holes up to 6 mm , which will make it possible to obtain pneumatic pressures up to 3.5 kg / cm3, for speeds below 130 km / h. Such a product can be applied to very light vehicles of the two-wheel type.

 The rubber particles can also have a particle size of less than 8 mm. Punctures can go up to 8 mm and pressures up to 4.5 kg / cm3. The speeds reached by such light vehicles, with four wheels, of utility type or tourism, cannot exceed 130 km / h.

 Finally, in a last embodiment, the rubber particles have a particle size between 0 and 1.2 mm.

The puncture holes repaired with this type of particle go up to 12 mm for pneumatic pressures up to 8 kg / cm3, the speeds are always lower than 130 km / h.

The application is carried out on very heavy vehicles such as heavy goods vehicles or public works vehicles.

 This work carried out on the rubber particles can also be carried out on the cellulose particles. However, these generally consist of 50% of flat particles, of substantially square shape, of approximately 2 mm on a side and of 50% of flat strips of approximately 2 mm by 60 mm. The puncture holes can reach 50 mm in these cases and the pneumatic pressures can go up to 10 kg / cm3. The application is that which is made to special heavy vehicles such as civil engineering vehicles, armored military vehicles.

 As seen above, the composition of the product may contain 2% of marking products. These products can have, in addition to their function of healing and antiseptic, the function of marking the offender who knowingly carried out the drilling of the tire. These formulations can be interesting in order to avoid any act of vandalism.

 In a second operating mode substantially identical to the previous one, the masses of products used are different; thus, 26 kg of toluene and / or xylene can be used, 30 kg of rubber powder, of which, for example, 20 kg have a particle size less than 0.4 mm and 10 kg whose particle size is between 0.4 and 0.8 mm. Total demineralized water can be 658 kg. The catalyst, that is to say sodium hydroxide, can be 0.36 kg as in the previous composition. Ditto for sodium nitrate acting as anti-rust which is in proportion to 3.5 kg. The hydrochloric acid which is used to adjust the pH value may be present in the proportion of 1 kg. 1.75 kg of Parmetol, 440 kg of monoethylene glycol, 3.8 kg of xanthan, 14 kg of colloidal coating agent, 40 kg of sealing agent and 7.6 kg of terpenes are also used.
