Definitions
- the invention relates to a method for depositing a coating protecting the internal or external surface of metal containers.
- These containers are intended to contain liquid to pasty products such as pharmaceuticals, parapharmaceuticals, cosmetics and food.
- These can be dispenser boxes for products in the form of an aerosol, foam or gel using pressurized gas.
- Metal containers protect the products they contain from contamination from the outside or from degradation of their composition by evaporation of one of their constituents.
- the metal wall is indeed an excellent barrier to diffusion of gases and aromas.
- the metal wall is generally coated internally with a layer of varnish intended to provide a lasting barrier at around 50 ° C. between the propellant gas, the products and said metal wall.
- the nature of the varnish and its thickness are chosen according to the products or the propellant contained. These are generally epoxy-phenolic compounds, vinyl organosols, polyesters, polyamide imides, etc.
- the varnish is deposited on the internal wall of the container by a gun which enters more or less deeply into the housing placed rotating (see Figure 1).
- the varnish is then dried by heat treatment or polymerized by UV excitation.
- a layer that is not very ductile is obtained, in general all the less ductile as it has good diffusion barrier properties. Due to this low ductility, it is necessary to limit the plastic deformation subsequently imposed on the container.
- the varnish is deposited on the inner face of the housing blank, that is to say before the open end is conified and before the bottom is fully formed. If the shrinkage corresponding to the conification is relatively well accepted by the varnish due to the compressive nature of the stresses generated, it is not the same for the operations of t ⁇ mponn ⁇ ge intended to carry out the rolled edge and for the operations of shaping the bottom of the case, these two types of shaping involving tensile stresses and leading fairly quickly to the creation of cracks on the varnish. This results in a loss of the desired barrier properties.
- WO95 / 22413, DE 43 18 086 or also FR 2 776 540 disclose complex devices making it possible to implement, at very high rates, the deposition of a plasma-assisted coating on the interior surface of a housing.
- the processes used have the common characteristic of imposing a fairly high vacuum inside the container. To satisfy this double constraint: very high rates and high vacuum, these devices are necessarily very expensive and can only be amortized economically with the production of a considerable quantity of containers thus treated.
- the Applicant Company has sought a reliable process for obtaining a coating which effectively protects the wall of metal containers, this process having to be economically satisfactory for the manufacture of metal containers which, like the boxes for aerosol dispensers, are produced at rates and in quantities typically ten to one hundred times lower than drink boxes.
- the object of the invention is a method of depositing a coating on the surface of a metal container, said method being assisted by plasma, characterized in that said method is carried out under a pressure close to atmospheric pressure.
- this deposition is carried out using a plasma surface treatment reactor.
- the plasma can be generated under different types of discharges: arc, luminescent discharge, discharge through a dielectric barrier or corona type discharge with different types of excitation: microwave, radio frequency, medium frequency alternating current.
- the last two types of plasma generation have the advantage of being able to be carried out under a pressure close to atmospheric pressure.
- the plasma can be generated • either by dielectric barrier discharge or corona type discharge between the housing and an electrode; in this case, the air gap must be fairly narrow, the deposit is preferably made before conification; • - either by using a transferred plasma generation mode: the plasma is formed outside the treatment zone by means of an arc discharge or a microwave or radiofrequency discharge. This plasma is then introduced inside the container by means of a sleeve which ensures the homogeneous distribution of the coating on the surface. interior of said container. The container is thus in a post-discharge position.
- the coating treatment can be carried out in “batch” on a quantity of cases in relation to the continuous flow of cases coming from the production line. Batch processing can be carried out completely independently of the production line, which includes the lacquering and / or over-varnishing of the outer surface of the boxes. But we can also consider integrating the treatment into the manufacturing cycle.
- the material to be deposited can be any material which does not react with the products and the propellant intended to be contained in the housing.
- the carbon with polymer tendency is chosen, that is to say comprising a network of amorphous carbon chains with hydrogen bonds, silica, alumina, any oxide, nitride or carbide or their mixture or their combination d one or more of the following metals (Si, Mg, Al, Ti, Zr, Nb, Ta, Mo, W, V) or a plastic material polymerized under plasma assistance.
- the aim is a deposit thickness of between 150 ⁇ and 1500 ⁇ , preferably 200 to 500 ⁇ .
- 100 A / s is targeted as an order of magnitude of the deposition rate. This is around 50 A / s when cold plasma is used (corona or dielectric type discharge); however, it can exceed 300 ⁇ / s with a pl ⁇ sm ⁇ type thermal plasma.
- the duration of the deposit can be limited to a few seconds, or even a few tenths of a second with plasma of the thermal plasma type. Even if it is necessary to treat several boxes simultaneously, it is possible to introduce into the production line accumulators of size identical to those used in the prior art for drying the varnish. The process allowing a higher deposition speed is preferred if it is a question of introducing a processing device integrated into the production line.
- a gas chosen from alkanes, alkenes or alkynes or their mixtures is preferably chosen as precursor gas.
- HMDSO hexamethyl-disiloxane
- TMDSO trimethyl-disiloxane
- precursor gas a gas of organometallic compound, such as tributyl aluminum AI (C H9) 3 or triethyl aluminum, is preferably used as precursor gas, which is circulated diluted in an argon mixture and oxygen.
- tributyl aluminum AI C H9 3
- triethyl aluminum is preferably used as precursor gas, which is circulated diluted in an argon mixture and oxygen.
- the chosen precursor acetylene for example
- one of the abovementioned gases HMDSO, TMDSO, tributyl-aluminum
- the mixture is determined so that the aluminum or silicon content of the deposit is close to or less than 5%. This is in fact to improve the adhesion of the deposit on the substrate but not to degrade the ductile behavior of the deposit too much, and thus avoid flaking at the time of the subsequent deformation.
- This process has the advantage of being able to be carried out under a pressure close to atmospheric pressure, preferably between 200 and 760 millimeters of mercury.
- a slightly lower pressure than atmospheric pressure allows better control of the purity of the gas circulating in the container.
- a preliminary sweep is carried out with an inert gas, of the argon type, to avoid the formation of impurities (risk of reaction with nitrogen in the air, water vapor, etc.) liable to deteriorate the quality. of the adhesion of the layer thus deposited.
- the deposition by dielectric discharge is carried out online, preferably in the middle of the production chain, on the blanks of casings not yet conified.
- An electrode of suitable shape is introduced to the bottom and to the cylindrical wall of the blank.
- the electrode must in fact be as close as possible to the wall to be coated (distance typically less than a centimeter). This encourages the use of an electrode conforming to the shape of the interior of the housing, which can be introduced into the housing before conification.
- the electrode is introduced into the interior volume of the housing.
- the latter, descending fairly low in the housing is preferably hollow, so as to supply the interior of the housing with precursor gas.
- a coating is chosen comprising carbon with a polymer tendency obtained by decomposition of a precursor 5 comprising a gas of alkene type. It is also possible to deposit a slightly crosslinked varnish obtained by plasma polymerization.
- the coating obtained much thinner than the layer of varnish of the prior art and better anchored on its substrate, indeed tolerates the compressive subsequent deformation w imposed by the conification without thereby cracking and thus losing the effectiveness of its properties. barriers.
- the substrate has, just before the deposition treatment, an activated, or at least well-cleaned, surface!
- This surface preparation can be ensured by the treatment provided in the prior art, where, before interior varnishing, the traces of lubricant (zinc stearate or equivalent) used to facilitate spinning by impact 0 are removed by performing a preferably thermal degreasing, or alternatively a chemical degreasing such as one of those conventionally used, that is to say by using a diluent of the perchlorethylene type or by practicing a hot washing of the inside of the housings with caustic soda followed by bleaching with nitric acid. 5
- the boxes are taken out of the transfer chain in a manner identical to that used for depositing interior varnish.
- the cycle having to be 5 to 15 times longer than that of varnishing, it is preferable to place the boxes on one or more rotary plates of larger diameter than that of the turrets 0 used for depositing varnish.
- the boxes are held by a device similar to that used on coniferous machines.
- the bottoms are put into their final shape (toroidal foot surrounding a concave dome) for example by dabbing before introducing the shape electrode into the housing.
- the deposition is carried out with a mode of generation of plasma transferred, either offline or preferably online, at the end of the production line when the housing is conified and the edge rolled is made around the opening.
- the second example shows a device where the plasma is formed by high frequency arc excitation.
- the plasma is introduced inside the container by passing through a sleeve, perforated, insulating and refractory. This sleeve is introduced into the interior of the housing and its open end is placed near the bottom so that the plasma must flow from the bottom of the housing to the opening. It is perforated over its entire height to let the plasma circulate throughout the interior volume of the container.
- provision is made to cool this sleeve by means of a double wall system with a circulation of water between the walls.
- the deposition by corona discharge is carried out online, preferably at the end of the production line, on the already confined casings.
- An electrode adapted to the opening is introduced: its orthogonal section has a contour having a large number of convexities and acute angles oriented towards the outside; but its envelope contour has a diameter smaller than that of the opening.
- the metal electrode can be easily inserted into the already confined housing and has longitudinal convexities and edges oriented towards the internal wall of the housing.
- the electrode, descending fairly low in the housing is preferably hollow, so as to supply the interior of the housing with precursor gas.
- FIG. 1 illustrates the gun used for coating a varnish used in the prior art.
- the gun 60 is introduced into the housing blank 1 (FIG. 1 b), that is to say the housing obtained after spinning but before conformation and shaping of the bottom 5.
- the blank is rotated R and the gun 60 distributes the varnish 61 on the inner face of said blank.
- FIG. 2 represents a device making it possible to coat the interior of the housings by excitation of a plasma under a pressure close to atmospheric pressure according to the second variant of the invention.
- Figure 3 shows schematically a device for coating the inside of the boxes by excitation of a plasma under a pressure close to atmospheric pressure according to the first variant of the invention.
- Example 1 Depositing an alumina coating on the internal wall of a monobloc aerosol can ( Figure 2)
- This example corresponds to the second variant of the invention: the method used makes it possible to coat the internal surface of a case 11 already shaped, having a neck 9 and a bottom 15, composed of an O-ring foot 7 surrounding a dome concave 6.
- the housing 11 is placed in an enclosure 16 in which it is possible to very quickly create a vacuum of the order of 300 mm of mercury.
- a small electrode 24 located in the center of the enclosure is brought into contact with the bottom 15 and the box is brought to a potential V making it possible to control the quality and the regularity of the deposit obtained.
- the assembly is moved so that it is placed opposite a transferred plasma generation device 21 secured to a sleeve 22.
- the sleeve 22 is then introduced into the housing 1 1.
- the pressure is brought to 300 mm of mercury and argon is injected through the sleeve 22 so that the ambient air stagnating in the housing is evacuated outside the enclosure.
- the sleeve 22 is generally made of quartz or ceramic. In this case, an alumina - zirconia mixture is used. It has a large number of small diameter perforations 23 (0 ⁇ 0.1 mm) passing through its thickness (of the order of 3 mm). These perforations are made over the entire height of the sleeve 22.
- the pumping means 17 of the enclosure 16 operate and create a pressure differential between the interior I of the housing and the enclosure E such that the gas injected into the housing flows up towards the neck.
- a tributyl aluminum (10%) argon (85%) and oxygen (5%) mixture is injected as a precursor gas.
- the plasma generated by a source excited at 250 kHz at a voltage of 10 kV, is flush with the internal surface of the housing by providing the elements making up the coating which is essentially composed of alumina but includes a little carbon with a polymer tendency. Ten seconds is enough to obtain a 250 A coating.
- Example 2. Deposition of a mixed carbon coating with a polymeric tendency and silica on the internal wall of an aerosol can blank ( Figure 3)
- This example illustrates the first variant of the invention. This involves depositing a coating on the internal surface of the boxes in the middle of the production chain, that is to say at a stage when the box is not yet conified. This stage is located in the production chain exactly at the current stage of depositing varnish of the prior art, which this process proposes to replace.
- the electrode 32 has a shape which conforms to within 2 mm the shape of the internal surface of a drawn spun blank 1. It is coated with a 20 ⁇ layer of polypropylene.
- the bottom of the blank has already been shaped: it comprises a toroidal foot 7 which surrounds a concave dome 6.
- the electrode is pierced with a conduit 31 which makes it possible to bring the precursor gas P into the air gap between the electrode and the housing
- the housing is placed inside a sleeve 30.
- a cap 33 carrying the electrode 32 is placed above the assembly, inside which primary pumping means are actuated before the cap is put in place. , so that the air is expelled (70) from the interior of the sleeve and the housing and is replaced by the inert gas supplied from the interior of the electrode.
- a pressure close to 300 mm of mercury is reached inside the enclosure.
- a contactor 34 is pressed against the bottom 5 'of the housing. This is brought to ground and a score of kV is applied to the electrode.
- the gas an acetylene - HMDSO -argon mixture, the flow rate of which corresponds respectively to 20 sccm, 10 sccm and 15 sccm (sscm being a unit meaning standard cm3 per minute) is injected and the plasma is generated by an excited source at a frequency of 250 kHz. A few seconds are enough to obtain a regular deposit of around 250 ⁇ .
- Example 3 Deposition of an alumina coating on the internal wall of an aerosol can blank
- This example corresponds to the third variant of the invention, where deposition by corona discharge is carried out at the end of the production chain, on the casings already conified.
- An electrode adapted to the opening is introduced: its orthogonal section has a contour having a large number of convexities and acute angles oriented towards the outside; but its envelope contour has a diameter smaller than that of the opening (25.4 mm).
- the metal electrode can be easily inserted into the already confined housing (diameter of the cylindrical body of the housing: 45 mm) and has longitudinal convexities and edges oriented towards the internal wall of the housing.
- the electrode is hollow, which makes it possible to supply the interior of the housing with precursor gas.
- a tributyl aluminum (10%) argon (85%) and oxygen (5%) mixture is injected as a precursor gas.
- the housing is the anode, the electrode the cathode.
- a voltage of 15 kV drawn at 200 kHz is imposed.
- the plasma is generated between the edges of the electrode and the internal p ⁇ roi of the housing distant from ten mm from these edges and comes flush with the internal surface of the housing by bringing the elements composing the coating which is composed essentially of alumina but includes a little carbon with polymer tendency
- An insulating sleeve is placed in the upper part of the electrode, which avoids preferential deposition at the neck.
