Definitions
- the present invention relates to a novel composition based on a functional polyolefin and comprising a crosslinking agent in high concentration.
- This composition can be used as a polymer crosslinking masterbatch. More particularly, this composition can advantageously be used to manufacture films encapsulating photovoltaic cells.
- Organic peroxides are commonly used for the crosslinking of thermoplastic resins or elastomers, these resins and elastomers being grouped together in the present description under the term "polymers".
- a peroxide is generally mixed with the polymer to be crosslinked in a first step, then a second polymer forming step is carried out and a third crosslinking step, for example by a heat treatment.
- the peroxides can be in liquid or solid form.
- they are mixed at high temperature, that is to say a temperature above the softening point of the polymer, for example by extrusion or kneading; the peroxides are then usually in a liquid form.
- compositions comprising an additional polymer and peroxides in high concentration, well known under the name of "master batch".
- master batch comprising an elastomeric polymer such as the ethylene-vinyl acetate copolymer, from 30% to 50% by weight of the composition of an organic peroxide, a plasticizer, a polyoctenamer as well as charges.
- the described masterbatch is manufactured by a mixer for thermoplastics by melting the polymers with the plasticizer and adding the peroxide and then the fillers.
- the masterbatch does not include a functional polyolefin.
- a photovoltaic module includes a "photovoltaic cell", this cell being capable of transforming light energy into electricity.
- a conventional photovoltaic cell this photovoltaic cell 10 comprises cells 12, a cell containing a photovoltaic sensor 14, generally based on treated silicon in order to obtain photoelectric properties, in contact with electron collectors 16 placed above (upper collectors) and below (lower collectors) of the photovoltaic sensor.
- the upper collectors 16 of one cell are connected to the lower collectors 16 of another cell 12 by conducting bars 18, generally consisting of a metal alloy. All these cells 12 are connected together, in series and / or in parallel, to form the photovoltaic cell 10.
- the photovoltaic cell 10 When the photovoltaic cell 10 is placed under a light source, it delivers a continuous electric current, which can be recovered at the terminals 19 of the stack 10.
- the solar module 20 comprises the photovoltaic cell 10 of FIG. 1 embedded in an "encapsulant" 22.
- Upper protective layer 24 and a lower protective film 26, also known as “backsheet”, are arranged on both sides of the encapsulated battery.
- this encapsulant 22 must perfectly match the shape of the space between the photovoltaic cell 10 and the protective layers 24 and 26 to prevent the presence of air, which would limit the efficiency of the solar module.
- the encapsulant 22 must also prevent the contact of the cells 12 with the water and the oxygen of the air, in order to limit the corrosion.
- this encapsulant is generally a composition comprising a polyolefin modified with a coupling agent in order to "encapsulate" the photovoltaic cell 10.
- the coupling agents are added in combination with a crosslinking agent, which also prevents creep of the encapsulant over time.
- Coupling agents are products generally chosen from organic silanes or titanates; the crosslinking agents are generally chosen from organic peroxides.
- the components are generally assembled by rolling, and the panel is pulled under vacuum via a silicone membrane.
- this silicone membrane tends to degrade in contact with these coupling agents. This is a major problem for photovoltaic module manufacturers at the moment because these silicone membranes are expensive and a shutdown of production is necessary for the time of their replacement.
- coupling agents tend to hydrolyze on contact with moisture and lose their activity over time.
- EP 1956661 A1 discloses a masterbatch, in admixture with a silane-modified polyethylene, used in photovoltaic cell encapsulants.
- This masterbatch comprises a metallocene polyethylene of particular density, a UV absorber, a light stabilizer and a thermal stabilizer and does not include peroxide or coupling agent.
- the subject of the invention is therefore a novel composition
- a novel composition comprising a mixture of a crosslinking agent and a first polyolefin comprising a functional monomer X chosen from unsaturated carboxylic acid or dicarboxylic acid anhydrides, unsaturated carboxylic acids and epoxides.
- unsaturated material capable of being cross-linked with a second polyolefin to form a support-supported assembly, said assembly and support forming a two-layered integral structure, characterized in that the amount of crosslinking agent is greater than or equal to 5% of the total mass of the composition.
- This composition has the advantage of being crosslinkable and adhesive, even in the absence of coupling agents.
- it is useful as a polymer crosslinking masterbatch, in particular polyolefins, whose adhesion capacity to substrates such as polymers, metals, metal oxides or silicon is to be increased.
- the amount of crosslinking agent is in the range of from 6 to 30% of the total weight of the composition, preferably from 7 to 16%.
- the crosslinking agent is, for example, an organic peroxide.
- the composition may further comprise a coupling agent, which is an agent capable of increasing the adhesive power of the composition.
- a coupling agent which is an agent capable of increasing the adhesive power of the composition.
- the polyolefin is preferably a polymer of:
- the polyolefin comprises, with respect to its total weight:
- the polyolefin comprises in relation to its total weight:
- the functional monomer (X) included in the polyolefin may be inserted therein by grafting or by copolymerization.
- the functional monomer (X) may be maleic anhydride.
- the support (24) is made of glass, poly (methyl methacrylate) (PMMA) or any other polymer composition combining these characteristics.
- composition according to the invention comprising:
- a third step of recovering the composition By using the processes carried out in the molten state, that is to say by mixing the compounds at a temperature above the softening temperature, a phenomenon of premature crosslinking of the composition can be observed because the activation temperature of the peroxide may be less than the processing temperature (as for example by following the process described in the documents US5589526, US3594342 and EP 1956661 A1).
- An advantage of this preferred method is that, in comparison with the melt processes, the phenomenon of premature crosslinking of the composition is limited and the manufacturing process is simple.
- composition obtained by this preferred method is also an object of the invention.
