Definitions
- the present invention relates to an adhesive or adhesive composition for textile, in particular a composition for adhering a textile to a rubber.
- the invention particularly relates to applications in the field of belts, pipes, tires, air springs (airspring) and, more generally, any part or article made of rubber, or comprising a part made of rubber, in which the rubber comprises a reinforcement.
- the invention is therefore also related to textile reinforcements coated with this adhesive, and the parts or articles incorporating them both in surface and in depth.
- the textile reinforcement must primarily ensure the dimensional stability of the belt. For this, it is requested reinforcement specific mechanical properties in various environments. To ensure the required properties, and in particular to avoid a risk of delamination, the reinforcement must adhere to the rubber of the belt.
- the reinforcement may be in contact with a rubber or several different rubbers. To allow good compatibility with the rubber, the reinforcement is usually treated with an adhesive. More complex properties may also be required for reinforcement. For example the edge of the reinforcement being cut and exposed to the side of the belt, it should not fray, while being easy to cut. To ensure these other properties, other types of treatments can be made to the wire.
- the chemical treatments are primarily aimed at adhering a given reinforcement to the different rubbers that it can meet.
- the treatments are as varied as there are types of reinforcements [glass, aramid, polyamide (PA), polyethylene terephthalate (PET), etc.] and families of rubbers.
- the core of the treatment for adhering a reinforcing textile to rubber is called resorcinol-formaldehyde-latex or RFL. It is a system mixing a latex (colloidal elastomer aqueous dispersion or of polymer) and thermosetting resins of the phenoplast or aminoplast type. This system is historical, it was largely developed in the 70s and remains the preferred treatment. Despite many attempts to replace, it has never been possible to offer a global solution to achieve its performance. It is completely optimized to obtain the maximum of static adhesion, that is to say out of dynamic stress.
- the heat treatment has an impact on the chemical properties (adhesion) but also mechanical in the case of synthetic reinforcements. It impacts withdrawal characteristics, among others.
- the treatment in the furnaces results from the consensus between the maintenance of the mechanical properties and the crosslinking of the adhesive.
- the new treatment must therefore be able to adapt to the current treatment conditions, in order to guarantee the mechanical properties.
- an adhesive allowing for a lower temperature treatment will potentially bring new and interesting properties in certain applications, and will have a favorable energy aspect.
- any change in a formulation does not call into question the functionality of the different treatments, both chemical and thermal (or physical, more generally) usually used for this or that application.
- RFL treatment has become the treatment of choice to allow adhesion between textile and rubber.
- the phenomena involved in the adhesion are involved during the vulcanization of the rubber part, while the RFL treatment itself can be deposited on the textile several months before. This is why the term “adhesion” treatment is often used, the term “adhesion” being rather reserved for the adhesion state.
- latex is a colloidal aqueous dispersions of elastomers or polymers, generally similar in nature to the rubber to be bonded. On the other hand, these latices do not have real mechanical properties in themselves.
- a thermosetting (thermosetting) resin is added to maintain the system.
- RF resin based on resorcinol and formaldehyde. Via its polarity, it allows a good adhesion to the textile. It forms a mesh in which the latex is trapped, which stiffens the system. This mesh remains sufficiently flexible to allow the diffusion of the elastomer chains in the matrix and then create good adhesion to the rubber (entanglement, molecular interactions and possibly co-curing during vulcanization).
- the RFL contains formalin and resorcinol, which are now suspected carcinogens. It would be interesting to find an alternative to formalin and resorcinol or RFL as a whole.
- the complex properties of the RFL both in terms of its implementation and in the end-use properties of the end products incorporating it, which have been recalled above, make the exercise of finding an alternative solution a real challenge. It would be even more interesting to find such a solution that is more than an alternative, but that allows an increase in performance. It is to meet these challenges that the inventors have set themselves.
- the aim of the invention is therefore to provide novel bonding solutions which make it possible in particular to replace RFLs in their known applications, with performance levels close to or even higher, and this with acceptable components in the context of sustainable development and in favorable economic conditions.
- Lignosulphonates are offered as a natural adhesive and as a short fiber binder for making mats (nonwovens) in combination with lignosulfonate hardeners, or as adhesives in wood-based multilayer products. They have never been proposed in compositions that are alternative to RFL and there is no indication that lignosulphonates may prove to be suitable for developing bonding formulas for bonding with rubbers, with sufficient mechanical performance.
- the subject of the invention is therefore an adhesive or textile adhesive composition
- an adhesive or textile adhesive composition comprising (or based on, consisting essentially of or consisting of) a lignosulfonate salt, an aldehyde hardener of this salt, and a polymer latex, in particular elastomer.
- the adhesive composition may be a suitable bonding composition for adhering textiles to a rubber or like material.
- the invention also relates to the use of an adhesive composition according to the invention, for imparting adhesion properties to a reinforcing textile, vis-à-vis a rubber or a similar material.
- the invention also relates to a reinforcing textile, especially a yarn, cord or textile structure, at least partially coated and / or impregnated with an adhesive composition according to the invention.
- the invention also relates to an article or piece made of rubber (or similar material) or comprising a rubber part (or similar material), in which the rubber comprises at least one reinforcement fabric according to the invention, at the surface and / or integrated inside the rubber or rubber matrix.
- the invention therefore firstly relates to an adhesive or textile adhesive composition
- an adhesive or textile adhesive composition comprising (or based on, consisting essentially of or consisting of) a lignosulfonate salt, an aldehyde hardener of this salt, and a latex of elastomer.
- reaction product is meant of course the product of the reaction between the lignosulfonate and the aldehyde, which does not include any additives that could enter the final composition.
- composition can in particular be obtained by a method, also object of the invention, according to which the three ingredients are mixed with stirring, and, preferably, the composition is cured.
- the lignosulfonate salt can be solubilized in water before mixing the solution obtained with the latex and with the aldehyde.
- This solubilization can be facilitated by working in a basic medium, by adding a sodium and / or ammonia type agent.
- the lignosulphonate salt solution and the latex are first mixed, then only the aldehyde is then added.
- the lignosulfonate salt in water with stirring and in the presence of the agent to be at basic pH is stirred until solubilization, preferably total, then added, with stirring, the latex, before incorporate, still stirring, the hardener (preferably it is previously dissolved or dispersed in water, eg with vigorous stirring).
- the method makes it possible to obtain a composition that can be left to mature (for example several hours, for example from about 2 to about 48 hours, for example between about 15 and about 25 ° C.) allowing the reaction product to form.
- the composition in particular after maturing, can be used as a ready-to-use or customizable adhesive composition.
- an aqueous solution of lignosulfonate and aldehyde hardener can be mixed before stirring an aqueous latex dispersion.
- the pH of the solution of lignosulfonate or lignosulfonate and hardener is adjusted to be basic, for example by addition of sodium hydroxide and / or ammonia, before incorporation of the latex.
- the composition can then be left to mature under the same conditions as above.
- the composition in particular after maturing, can be used as a ready-to-use or customizable adhesive composition.
- the bonding composition comprises a reaction product between hardener and lignosulfonate.
- This composition may especially be characterized by the absence or a reduced rate of hardener in the free state.
- the ripening conditions are suitable for obtaining an adhesion composition that can be used in accordance with the invention. In particular, these conditions must not cause caking or excessive hardening of the composition which would render it unsuitable for its application on the media for which it is intended. It has been defined here a ripening of especially several hours, for example from about 2 to about 48 hours, for example at a temperature between about 15 and about 25 ° C. However, it may be possible to deviate from these conditions according to the ingredients used as the adhesive composition remains suitable for its use as described below, for example in terms of viscosity.
- the latex is preferably a basic aqueous dispersion of the polymer (s) and / or elastomer (s). It is also possible to work according to the invention at neutral pH. The working pH values may in particular be those mentioned below with respect to the pH of the composition.
- elastomer is meant, in particular, a polymer or copolymer chain whose glass transition temperature (T v ) is less than about 25 ° C. The elastomers are present in the rubber to be adhered and in the latex of the bonding composition.
- An “elastomer latex” is an aqueous colloidal elastomer dispersion.
- rubber or “elastomeric material” is meant here the vulcanized or crosslinked product prepared from elastomer or elastomeric gum, synthetic or natural, of one or more types, of filler ( s) reinforcing (s) (carbon blacks, silica, kaolins ...), plasticizer (s), vulcanizing agent (s) (sulfur, peroxide, metal oxides and necessary accelerators), possible other usual additives for the application in question (for example to facilitate the implementation, for protection against oxygen, ozone, heat, flame, UV).
- the invention is as much concerned with synthetic rubbers as with natural rubber. Rubbers, formulated based on elastomers, are materials whose T v obtained is then lower than the working temperature of the part.
- Lignosulphonates are by-products of wood processing, including the treatment of wood for the manufacture of paper pulp using the so-called "acid sulphite baking process". This process, which employs a bisulfite, makes it possible, depending on the nature of the counterion employed, to obtain the corresponding lignosulfonate salts. These lignosulfonates can also be from a die intended to produce them from wood.
- the lignosulfonate salt may be a salt of sodium, potassium, magnesium, ammonium or calcium.
