Definitions
- the present invention relates to a method for manufacturing painted or lacquered glass comprising a step of creating visible patterns in the paint or lacquer layer by orientation and / or displacement of magnetizable particles by means of a magnetic field.
- the exposure of the magnetizable particles contained in the liquid composition to the magnetic field lines causes a change in the organization of the particles and the creation of visible patterns by concentration or selective orientation of the particles.
- the permanent magnets or electromagnets are integrated in the surface of at least one of the rollers of the conveyor carrying the glass sheet.
- the tangential velocity of the magnets is always equal to the conveying speed of the glass sheet, the identity of these two speeds guarantee a regular spacing of the patterns or images created.
- the known method does not allow to easily create large patterns: the size of the patterns in the direction of travel of the glass sheet is indeed limited to the circumference of the conveyor roller in which the magnets are incorporated.
- the purpose of the present invention is to propose a method similar to that described in applications WO2014 / 009306 and WO2015 / 071 125, but which makes it possible to create large patterns without the need to increase the size of one or several of the conveyor rollers.
- the method of the present invention operates with an endless, magnetic and magnetizer belt mounted on at least two conveyor rollers.
- the size of the carpet in the direction of travel of the glass sheet is larger than the circumference of each of the conveyor rolls and determines the maximum dimension of the magnetic patterns that can be created.
- the use of an endless belt does not imply any increase in the size of the conveyor, compared to a similar conveyor without carpet.
- the subject of the present invention is therefore a process for manufacturing lacquered glass comprising
- the method being characterized in that the device for creating a magnetic field 9 is an endless belt 6 mounted on at least two rollers 2 of the conveyor, of which at least one is driven by a motor, the endless belt 6 being provided on its surface with one or more magnetic elements 7.
- the method of the present invention further has the advantage of giving, for a given scrolling speed, a better resolution than the method of the state of the art. Each point of the glass sheet remains in contact with the magnetic element or elements fixed on the carpet for a longer duration than if these same elements were fixed on a conveyor roll,
- the increase in the duration of contact of the magnetic element (s) with the glass substrate may also make it possible, for a given quality of resolution, to make the process operate at a higher rate or speed of scrolling.
- the dimensions of the endless carpet magnetizer can be chosen freely according to the number and the size of the patterns and images that one wishes to create: the larger the size of the patterns or images, the greater the width and the length of the carpet must be large.
- the dimensions of the endless carpet can be chosen between wide limits: its length in the direction of travel of the glass sheet is for example between 50 cm and 10 m, preferably between 80 cm and 5 m, in particular between 1 , 5 m and 4 m.
- the width of the carpet, in the direction perpendicular to the direction of travel of the glass sheet is advantageously between 40 cm and 4 m, preferably between 80 cm and 3.5 m and in particular between 1.0 m and 3 m, 0.
- the magnetic elements, or magnets are preferably permanent magnets, easier to implement than electromagnets.
- Examples of magnetic materials that may be used for the process according to the invention include steels, ferrites, alloys composed mainly of aluminum (Al), nickel (Ni) and cobalt (Co) (Alnico), samarium and cobalt based alloys and neodymium, iron and boron alloys.
- the magnetic elements may protrude from the surface of the endless carpet, they may be flush with the surface of the carpet, or they may be slightly recessed from the carpet surface. In all three cases, it may be interesting to cover the surface and the magnetic elements with a thin plastic film in order to protect them, to better hold them in place or to facilitate their cleaning.
- the endless belt is made of a flexible tensile material, preferably an organic polymer sheet.
- the deposition of a layer of a liquid composition containing a curable organic binder and magnetizable particles on one side of the glass sheet can be done by known methods, for example by spraying, by roller application or by application to the curtain.
- the liquid composition contains at least one organic binder, preferably a polymeric binder.
- Curing is understood to mean any step which has the consequence of increasing the viscosity of the liquid composition to a level sufficient to freeze the magnetizable particles in their position and prevent any modification or disappearance of the pattern even when the initial magnetic field disappears or is replaced by a different magnetic field.
- Curing can be done by simple evaporation of a solvent, or by a polymerization reaction and / or crosslinking of the monomers, oligomers and / or polymers forming the organic binder, initiated by heating or irradiation of the liquid composition layer.
- organic binder is not critical to the practice of the present invention and any film-forming base of paint, lacquer, ink or varnish can be used in principle.
- Magnetizable particles are known as such. They may be ferromagnetic or paramagnetic particles. They preferably, but not necessarily, have an anisotropic form, particularly an elongated or flattened form. Such particles are described for example in the following applications and patents: US 3,676,273, US 4,838,648, WO 02/073250, EP 686,675 or WO 2007/131833.
- the magnetizable particles preferably represent between 10 and 70% by weight of the liquid composition, in particular between 20 and 60% by weight of the liquid composition.
- the liquid composition may further contain non-magnetizable pigments and other adjuvants conventionally used in paints, lacquers and varnishes.
- the first layer of liquid composition contains, as single pigments, magnetizable particles. After curing, the layer then has a certain translucency and may advantageously be covered with a second pigmented layer, free of magnetizable particles.
- the liquid composition layer containing the curable organic binder and the magnetizable particles is applied to the glass sheet preferably in an amount such that the surface weight of the dried and cured layer is between 30 g / m 2 and 250 g / m 2 .
- the thickness of the dried and cured layer is advantageously between a few microns and several tens of microns, for example between 1 and 200 microns, preferably between 5 and 150 microns, in particular between 10 and 100 microns.
- the curing device may for example be a chamber heated typically at a temperature between 50 and 200 ° C, or a radiation source emitting radiation absorbed by one or more components of the organic binder, for example by initiators or photoinitiators.
- the radiation may be radiation in the visible, UV or infrared range, preferably near infrared.
