Definitions
- thermoplastic composite material based on nanotubes, in particular carbon
- the present invention relates to a process for the preparation of composite materials based on nanotubes, in particular carbon, the composite materials thus obtained, as well as their use for the manufacture of composite products.
- Carbon nanotubes have particular crystalline structures, tubular, hollow and closed, composed of atoms regularly arranged in pentagons, hexagons and / or heptagons, obtained from carbon.
- CNTs generally consist of one or more coiled graphite sheets.
- One-sided nanotubes Single Wall Nanotubes or SWNTs
- Multi Wall Nanotubes or MWNTs are thus distinguished.
- CNTs are commercially available or can be prepared by known methods. There are several methods of synthesis of CNTs, including electrical discharge, laser ablation and chemical vapor deposition or CVD (Chemical Vapor Deposition) which ensures the production of large quantities of carbon nanotubes and therefore obtaining them at a cost price compatible with their massive use.
- This process consists precisely in injecting a source of carbon at relatively high temperature over a catalyst which may itself consist of a metal such as iron, cobalt, nickel or molybdenum, supported on an inorganic solid such as alumina, silica or magnesia.
- Carbon sources can include methane, ethane, ethylene, acetylene, ethanol, methanol or even a mixture of carbon monoxide and hydrogen (HIPCO process).
- the CNTs have both excellent stiffness (measured by the Young's modulus), comparable to that of steel, while being extremely light. In addition, they have excellent electrical and thermal conductivity properties that allow to consider using them as additives to impart these properties to various materials, including macromolecular.
- Some solutions have been proposed to facilitate the dispersion of CNTs in a polymer matrix. These include sonication, which has only a temporary effect, or ultrasonication which has the effect of partially cutting the nanotubes and creating oxygenated functions that can affect some of their properties.
- Another solution consisted in carrying out a dispersion of NTC in a solvent and a monomer and carrying out an in situ polymerization leading to the production of functionalized NTC. This solution is however complex and can be expensive depending on the products used.

- the ingredients of formulation IB were partly introduced into the same hopper (polyamide and nanotubes) and partly injected with a gravimetric dosing pump into the first zone of the co-kneader (BBSA), which corresponds to the beginning of the melting of the polymer.
- BBSA co-kneader
- formulation IA generates deposits in the co-kneader, contrary to the formulation IB.
- the method according to the invention makes it possible to manufacture a composite material with a high dosage of nanotubes in milder conditions than a process which does not use a plasticizer. This process therefore makes it possible to continuously manufacture composite materials without degrading the polymer matrix or generating unacceptable pollution of the equipment.
- the composite product manufactured according to the invention (MB with BBSA) has electrical conduction properties at a lower temperature than the comparative composite product (MB without BBSA).
- the invention thus makes it possible to obtain composite products under milder process conditions, preserving the polymer matrix.
- the ingredients of formulation 3A all solid, were introduced into a single hopper.
- the ingredients of the formulation 3B were partly introduced into the same hopper (polyamide and nanotubes) and partly injected with a gravimetric dosing pump, on the one hand (10% BBSA) in the first zone of the co-kneader corresponding to the beginning of the melting of the polymer and, on the other hand (5% BBSA), in the second zone of the co-kneader, downstream of this melting zone.
- the formulation 3A was more viscous and resulted in a power consumption of 5.7-5.8 kW for the co-kneader, which exceeded after 10 h of compounding the nominal power indicated by the manufacturer (6.0 kW) , thus requiring to reduce the flow rate to 10 kg / h.
- the temperature of the material in the last zone of the co-kneader rose to about 32O 0 C.
- the method according to the invention makes it possible to continuously manufacture materials composites strongly dosed in NTC without degrading the polymer matrix nor polluting the equipment.
- the use of the composite material manufactured according to the invention makes it possible to reduce the manufacturing temperature of the composite product by 20 ° C., while giving the latter the same electrostatic dissipation properties.
- the ingredients of formulation 5A all solid, were introduced into a single hopper.
- the ingredients of the formulation 5B were partly introduced into the same hopper (polycarbonate and nanotubes) and partly injected with a gravimetric dosing pump, equipped with a liquid heating system at 80 ° C., in the first zone of the co-kneader corresponding to the beginning of the melting of the polymer.
- the temperature setpoints were similar for the two formulations (zone 1 / zone 2 of the co-kneader: 300/260 ° C. and 310/270 ° C.).
- These composite materials can be diluted up to 2-3% by weight of NTC in a polymer matrix based on polycarbonate, ABS resin or ABS / styrene copolymer, for the manufacture of conductive materials and flame retardants (that is to say having a VO index at UL94 fire test and LOI greater than 32%).
- the use of the composite material manufactured according to the invention makes it possible to reduce by 20 ° C. the manufacturing temperature of the composite product, while giving the latter the same properties of electrostatic dissipation.
- Example 3 was repeated except that the plasticizer was fully introduced into the co-kneader downstream of the PA-6 melting zone.
- a precomposite containing 50% by weight of propylene glycol and 50% by weight of carbon nanotubes was introduced into the first doser of a CLEXTRAL BC21 co-rotating twin-screw extruder.
- a mixture of powders consisting of 40% by weight of poly (ethylene glycol) (CLARIANT PEG 1500, 40% by weight of CLARIANT carboxymethyl cellulose and 20% by weight of dodecyl was introduced.
- benzene sodium sulfonate was introduced into the first doser of a CLEXTRAL BC21 co-rotating twin-screw extruder.
- the compounding was carried out at a set temperature of 100 ° C., with a rotational speed of the screw of 600 rpm and at a flow rate of 10 kg / h.
- the masterbatch obtained which contained (to be completed)% by weight of CNT, was conditioned in the solid state without granulation at the die outlet. It may be introduced into a solvent formulation after being impregnated for a few hours at room temperature with a mixture of solvents present in said formulation.
- the solid ingredients of the formulations 10A and 10B were in part (polymer and nanotubes) introduced into the same feed hopper and in part (plasticizer) injected with a gravimetric dosing pump into the first zone of the co-kneader corresponding to the melting of the polymer.
- the pump was equipped with a liquid heating system at 160 ° C. for formulation 8A and at 100 ° C. for formulation 8B.
- the temperature setpoints were similar for the two formulations (zone 1 / zone 2 of the co-kneader: 220/200 ° C.).
- the material temperature did not exceed 24O 0 C despite the high content of CNT (30%). It emerges from this example that the process according to the invention makes it possible to continuously manufacture composite materials with a high NTC content without degrading the polymer matrix.
