Definitions
- Adhering composition for textile and related reinforcing textile are Adhering composition for textile and related reinforcing textile
- the present invention relates to an adhesive or bonding composition for a textile, in particular a composition for making a textile adhere to a rubber.
- the invention relates in particular to applications in the field of belts, pipes, tires, pneumatic 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. textile on the surface and / or in depth (in the mass).
- the invention therefore also relates to textile reinforcements coated with this adhesive, and the parts or articles incorporating them both on the surface and in depth.
- the textile reinforcement must first and foremost ensure the dimensional stability of the belt.
- the reinforcement is required to have specific mechanical properties in various environments.
- the reinforcement must adhere to the rubber of the belt.
- the reinforcement can be in contact with one rubber or several different rubbers.
- the backing is generally treated with an adhesive. More complex properties may also be required from the reinforcement. For example, the edge of the reinforcement being cut and exposed to the side of the belt, it must not fray, while being easy to cut. To guarantee these other properties, other types of treatments can be applied to the wire.
- the primary aim of the chemical treatments is to make a given reinforcement adhere to the various rubbers that it may encounter.
- the treatments are as varied as there are types of reinforcements [glass, aramid, polyamide (PA), polyethylene terephthalate (PET), etc.] and families of rubbers.
- the heart of the treatment for making a reinforcing textile adhere to the rubber is the so-called resorcinol-formaldehyde-latex or RFL treatment. It is a system mixing a latex (colloidal aqueous dispersion of elastomer or polymer) and thermosetting resins of the phenoplast or aminoplast type. This system is historic, it was widely developed in the 1970s and remains the treatment of choice. Despite numerous replacement attempts, it has so far never been possible to offer a global solution to achieve its performance. It is completely optimized to obtain the maximum static adhesion, that is to say without dynamic stress.
- the heat treatment has an impact on the chemical properties (adhesion) but also on the mechanical properties in the case of synthetic reinforcements. It impacts the withdrawal characteristics, among others.
- the treatment in the ovens 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 current processing conditions, in order to guarantee the mechanical properties.
- an adhesive allowing a treatment to be carried out at a lower temperature will potentially provide new and interesting properties in certain applications, and will exhibit a favorable energy aspect.
- Thread core treatment which traps the filaments in a matrix and locks the filaments together. It thus gives resistance to fraying and makes the yarn stiff.
- Overcoats in English “overcoats" in the form of commercial adhesion promoters, or solutions of elastomers (sometimes called cementation).
- any change in a formulation does not call into question the functionality of the various chemical and thermal (or physical, more generally) treatments usually used for such and such an application.
- the RFL treatment has emerged as the treatment of choice to allow adhesion between the textile and the rubber.
- the phenomena involved in adhesion are brought into play during the vulcanization of the rubber part, while the RFL treatment itself can be deposited on the textile several months before.
- the term “adhesion” treatment is often used, the term “adhesion” being rather reserved for the state of adhesion.
- latexes are colloidal aqueous dispersions of elastomers or polymers, generally similar in nature to the rubber to be bonded. On the other hand, these latexes do not have real mechanical properties in themselves.
- a thermoset resin thermosetting
- RFL contains formalin and resorcinol which are now suspected carcinogens. It would therefore be interesting to find an alternative to this formalin and to resorcinol or to the RFL composition as a whole.
- the complex properties of RFL both in its implementation and in the properties of use of the end products incorporating it, which were recalled above, make the exercise of finding an alternative solution a real challenge. It would be even more interesting to find such a solution which is more than an alternative, but which allows an increase in performance.
- the objective of the invention is thus to provide new adhesion solutions which make it possible in particular to replace RFLs in their known applications, with performance levels that are close to or even higher, and this with components that are acceptable in the context of sustainable development and under favorable economic conditions.
- Lignosulfonates are offered as a natural adhesive and as a binder of short fibers for making mats (nonwovens) in combination with lignosulfonate hardeners, or as adhesives in multi-layer wood-based products. They have never been proposed in alternative compositions to RFLs and there is no indication that lignosulfonates can prove to be suitable for developing adhesion formulas to ensure a bond with rubbers, with sufficient mechanical performance. They are also used as surfactant in compositions then containing no hardener, as described in JP2002226812 and JP2001234143.

- heat such as a heat treatment which will be applied to the textile once coated and / or impregnated with the adhesion composition.
- the lignosulfonate salt is expected to react with the epoxy hardener in a crosslinking reaction by adding the reactive units of lignosulfonate to the epoxy rings and opening this ring, when the compounds are subjected to heat. This heat can be applied during a heat treatment such as the heat treatment applied to a textile after coating and / or impregnation of the adhesion composition.
