Definitions
- Sealant for temporarily sealing vehicle tires method for temporarily sealing a vehicle tire and use of such a sealant
- the invention relates to a sealant for temporarily sealing vehicle tires according to the preamble of patent claim 1, a method for temporarily sealing a vehicle tire according to the preamble of patent claim 8 and a use of the sealant according to patent claim 10.
- Pneumatic vehicle tires can suffer damage in the form of cracks when driving over sharp objects, which can lead to a loss of air pressure in the tire.
- sealing means are known in the prior art which can be applied after the valve insert has been unscrewed or directly via the valve in the tire, e.g. using a device with a pressure source and sealants are introduced.
- EP 3 227 097 B1 discloses a means for sealing with a rubber latex, adhesive resin and antifreeze.
- a disadvantage of the sealants described in the prior art is that the compositions do not have the desired properties in terms of injection behavior and sealing behavior for a tire.
- the object of the invention is to provide a sealant for the temporary sealing of pneumatic vehicle tires has improved sealing properties and flow properties and, in particular, lower production costs. Furthermore, the invention is based on the object of providing a method for temporarily sealing a pneumatic vehicle tire that efficiently seals the pneumatic vehicle tire.
- the object is achieved by a sealant for temporarily sealing vehicle tires, containing at least one rubber latex and at least one resin, the sealant having a proportion of rubber latex of 27 to 46% by weight and a proportion of resin of 2 to 13% by weight. having.
- the sealant has significantly improved delivery or flow properties, so that the sealant can be pumped more quickly into the pneumatic vehicle tire.
- the sealant exhibits significantly better sealing properties, as a result of which holes in the tire can be sealed better. This can be shown, among other things, by improved properties in relation to the leakage rate after sealant injection and the total application time.
- the pneumatic vehicle tire can be inflated more quickly and sealed better with such a sealant.
- the manufacturing cost improves.
- weight data relate to the total amount of sealant or to the total amount of agent for temporarily sealing inflatable or inflatable objects.
- the rubber latex can be a natural rubber latex from Hevea brasiliensis or latex from the guayule bush (Parlhenium argentatum), it being possible for the natural rubber latex to be used in deprotonated form. It is also conceivable that the latex is produced and used synthetically. The use of different latices in a blend is also conceivable.
- the sealant has a latex content in the range from 36 to 45% by weight.
- the sealant thus advantageously exhibits a better leakage rate after application.
- a latex which is an aqueous dispersion (emulsion) of up to 70% by weight, particularly preferably up to 60% by weight.
- emulsion aqueous dispersion of up to 70% by weight, particularly preferably up to 60% by weight.
- proportion of solids in the dispersion, based on the total weight is up to 70% by weight, particularly preferably up to 60% by weight.
- this has at least one resin with a resin content preferably in the range from 2.5 to 12.5% by weight, particularly preferably in the range from 2.5 to 10% by weight particularly preferably in the range from 4.5 to 10% by weight. It could be shown that the sealant with a lower resin content than in the prior art leads to improved properties and additional costs can be saved in the manufacture of the sealant.
- a resin which is an aqueous dispersion (emulsion) of up to 60% by weight, particularly preferably up to 50% by weight.
- emulsion aqueous dispersion of up to 60% by weight, particularly preferably up to 50% by weight.
- proportion of solids in the dispersion, based on the total weight is up to 60% by weight, particularly preferably up to 50% by weight.
- Adhesive resins which act as tackifiers are preferably used.
- these adhesive resins are selected from the group consisting of rosins and their esters, terpene-phenolic resins, alkyne-phenolic resins, phenolic resins and coumarone-indene resins.
- Sealants containing such adhesive resins show a particularly high adhesive strength with a good sealing effect and have a positive influence on compatibilization with other components in the sealant.
- Rosin resins can be extracted from the tree resin of various softwoods and consists essentially of a mixture of resin acids and terpenes.
- terpene-phenolic resins are those resins that are made by the acid-catalyzed addition of phenols.
- alkyne-phenolic resin resins can be used which, as an alkyne, e.g. B. ethyne and as a phenol component, for example butylphenol or novolaks from formaldehyde and, for example, p-tert. butyl phenol (or p-diisobutyl phenol).
- Coumarone-indene resins are obtained as copolymers during the polymerization of the unsaturated compounds contained in the light oil of coal tar.
- the sealant has a resin to latex ratio in relation to the solids content of latex and resin in the range from 4 to 40% by weight, in particular in the range from 15 to 32% by weight.
- the sealant comprises at least two antifreeze agents, in particular at least one antifreeze agent having at least one glycol selected from the group consisting of an ethanediol and a propanediol and a butanediol. Glycols are commonly used in antifreeze.
- the antifreeze has a low freezing point, which is usually below -10°C. In combination with water, the freezing point is even lower and can reach -55 °C with the right mixture.
- the sealant with a low freezing point can be used in colder regions without the pumpability and flow properties being significantly impaired.
- the first antifreeze contains 1,2-ethanediol and the second antifreeze contains 1,2-propanediol. Both antifreezes are miscible with water and reduce the freezing point.
- the sealant with such an antifreeze is more environmentally friendly.
- the total proportion of antifreeze is preferably in the range from 27 to 40% by weight, in particular the proportion of the first antifreeze in the range from 20 to 25% by weight and the proportion of the second antifreeze in the range from 7 to 15% by weight. % lies.
- this total proportion of antifreeze is optimal for lowering the freezing point of the entire sealant, so that it can also be used at lower temperatures with optimal pumpability and flow properties and improved sealing properties.
- the sealant comprises at least one surfactant, with the total proportion of the surfactant in particular being in the range from 0.25 to 5% by weight.
- the at least one surfactant advantageously stabilizes at least the latex and in particular an antifreeze, as a result of which the sealant is stabilized overall.
- the sealant particularly preferably contains two surfactants, the total proportion of the first and second surfactants being in the range from 0.5 to 2% by weight.
- the two surfactants can interact with each other and with other components, so that the conveying properties and the sealing properties are improved.
- the at least one surfactant also preferably has one or more sulfonates, in particular anionic mono- or disulfonates and/or at least one alkyl ether sulfate, such as sodium alkylphenol polyethylene glycol ether sulfate, and at least one steric surfactant.
- these are good foaming agents, as a result of which sealing in pneumatic vehicle tires is significantly improved.
- Steric surfactants have a good viscosity and foam-regulating effect on the sealant.
- the sealant can contain other customary additives in customary amounts. Anti-aging agents or preservatives can thus be added to the sealant to ensure that the sealant is ready for use during storage.
- the sealant may contain dispersing agents, emulsifying agents and pH regulators.
- the sealant preferably contains 1 to 2% by weight of at least one aging inhibitor, in particular dispersions of sterically and alkylated (poly)phenols and/or alkylated diphenylamines.
- the sealant can thus be made to last longer.
- fillers to the sealant, which contribute to the sealing of larger holes in particular.
- fibrous materials in particular natural and synthetic fibers, phyllosilicates, silicic acid, talc, chalk, soot, rubber powder and the like.
- the sealant also preferably has a viscosity at 25° C. of 3 to 23 mPa*s, in particular 6 to 16 mPa*s (dynamic viscosity on the rheometer, 0.5° cone, 16000 rpm). This significantly improves the flow properties of the sealant.
- the invention relates to a method for temporarily sealing a pneumatic vehicle tire using at least one sealing agent described.
- An essential advantage of this method is that the sealing of a pneumatic vehicle tire can be carried out much more easily and quickly with the sealing means described.
- the sealing process can already take place during the filling process.
- the sealant is preferably sprayed in through a valve of the pneumatic vehicle tire.
- Using the sealant described can improve the injection behavior at the valve, since the delivery properties of the sealant described are improved.
- the invention relates to the use of the described sealant in a breakdown repair kit for a pneumatic vehicle tire.
- Pneumatic vehicle tires are usually repaired with a breakdown kit, wherein breakdown kits have, for example, a container with the sealant described, which is conveyed into the pneumatic vehicle tire for sealing.
- Further advantages and features of the method according to the invention and of the device result from the dependent claims, which relate to advantageous configurations of the present invention and as such are not to be understood as limiting.
- the invention also includes combinations of the features of different subclaims, insofar as these are technically possible, even if the subclaims do not relate to one another or if they belong to different claim categories.
- combinations of preferred and particularly preferred embodiments can also be combined with one another, insofar as these are technically possible. This also applies to the individual features of the exemplary embodiments discussed below, insofar as these are not recognizable to the person skilled in the art as necessarily belonging to one another.
- the invention is to be explained in more detail on the basis of the following exemplary embodiments.
- the example marked with “V” is a comparative example.
- Compositions according to the invention are marked with “E”.
- the viscosity was determined using a rheometer in the plate/cone configuration at 16,000 rpm and 25°C.
- a leak is generated by penetrating the tread of a pneumatic vehicle tire with a 6 mm nail.
- the leakage rate which is a measure of the size of the hole, is determined at a tire inflation pressure of around 2.5 bar. Based on this determination method, the leakage rate can be determined before the application of the sealant LR before and after the total pumping phase LR after. This allows the quotient of both leakage rates LRnach/LRvor to be calculated. This is a measure of the sealing efficiency.
- the quotient of the leakage rate and the total application time as a function of the resin/latex ratio in relation to the total solids content from Table 1 are shown in FIG.
- Table 1 shows that the examples according to the invention have significantly better properties in relation to the total application time (smaller value is better) and the quotient of the leakage rate (smaller value is better).
- the Manufacturing costs are advantageously reduced with a lower resin content compared to conventional sealants.
- Substances used a) 60% solids by weight, LATZ natural latex, e.g. Weber & Schaer b) Rosin ester, 50% solids by weight, Tacolyn, Eastman Chemical Company c) Aromatically modified terpene resin, Nanolet TO, Yasuhara chemical Co. Ltd d) anionic disulfonate, 51% by weight active solids e) sodium trialkylphenol polyethylene glycol ether sulfate, 25% by weight active solids f) resin/latex ratio in terms of latex and resin solids content
