Definitions
- the present invention relates to an improved process for indirect coating of a thin layer, that is to say a coating in which the material, in a conventional manner, is applied in a layer on a support. which scrolls in front of a cylinder, which continuously transfers the coating material to a support.
- the invention also relates to an improved coating device.
- a coating is carried out on a support in a flexible material which circulates in the form of a continuous strip over an applicator cylinder.
- This applicator cylinder also called a metering cylinder
- This applicator cylinder is either in contact with another so-called transfer cylinder (or soaking roller) which is partially immersed in a tank or reservoir containing the coating composition, or more generally is directly immersed in part in such a tank or tank.
- One or more counter-cylinders are provided above the support by exerting a pinching effect (nip).
- nip a pinching effect
- Different embodiments of coating installation are described in the book Kunststoff Maschinen Fuhrer 3. Ausgabe, Cari Hanser Verlag-Mùnchen [0006] Devices of this type are widely used, in particular in the production of various floor and wall coverings.
- compositions suitable for this use have been described in European patent application number 00870129.4 of 06.15.2000 in the name of the Applicant.
- doctor blade or doctor-doser which equalizes the material before its contact with the support which must to be coated.
- the invention aims to avoid the drawbacks of the techniques used so far and aims to ensure at the outlet of the container containing this composition, an adequate equalization of the coating composition taken up by the applicator cylinder.
- an applicator cylinder is used receiving the coating composition contained in a tank or tank in which the applicator cylinder is partially immersed.
- the emerging part of the applicator cylinder for the purpose of equalizing the coating composition, is in contact with an equalizing cylinder provided with a coating of an elastomeric material, rotating or not in the same direction of rotation as the applicator cylinder and whose peripheral speed of rotation is different from that of the applicator cylinder.
- the installation used is conventionally constituted by a soaking tank, an applicator cylinder partially submerged in this tank and an equalizing cylinder of the coating composition for the support to be coated which is in contact with the emerging part of the applicator cylinder.
- That of the invention does not include a doctor blade or equalization doctor acting on the material supplied by the applicator cylinder, but involves the use of an equalizing cylinder provided with a coating of 'An elastomeric material, rotating or not in the same direction of rotation as the applicator cylinder and whose peripheral speed of rotation is different from that of the applicator cylinder.
- the elastomeric coating chosen for the equalizing cylinder has a hardness sufficient to cause an equalization and smoothing effect. It is preferably a rubber type material having a Shore hardness of the order of 45 to 80, preferably in the range of 65 to 70 Shore units.
- a non-adherent material is chosen for the coating composition. Even in the case of a composition comprising highly abrasive fillers, no marked wear effect is observed for long periods of operation of the equalizing cylinder.
- the applicator cylinders used are conventionally engraved cylinders, of the rotogravure cylinders type, in particular cylinders comprising engravings of the pyramid, truncated pyramid, conical type or lines of helical engravings intended to retain the coating composition taken during passage in the soaking tank.
- the volume deposited on the support generally corresponds to 10 to 100 ml / m 2 of a (wet) composition with a density of 1. In practice, the density is between 0.8 and 1.5.
- thin layer is meant a coating film of the order of a few microns to 120 microns, preferably of the order of 5 ⁇ m and 70 ⁇ m (thickness of the film of dry and possibly crosslinked coating material made on the support).
- the peripheral (linear) speed of the applicator cylinder is of the order of 20 to 40 m / min.
- the ratio of the peripheral speeds of the equalizing cylinder and the applicator cylinder is achieved by adjusting the speed of rotation (revolutions per minute) of the equalizing cylinder, taking into account the respective diameters of the cylinders and, of course, the directions of rotation.
- the choice of these relative speeds is essentially dictated by considerations of viscosity of the coating composition.
- the installation includes the usual auxiliary equipment such as detour rollers or rollers, drying and / or crosslinking devices - UN or others, support unwinders and reels for the coated support, bin level regulator soaking, device for adjusting the spacing of the cylinders, and drive and cutting mechanisms, etc.
- the attached figure shows schematically a view of an installation according to the invention.
- the direction of rotation of the different cylinders and rollers is indicated there schematically by arrows.
- a soaking tank 1 containing a coating composition 3 kept level by suitable equipment receives an applicator cylinder 5. This is in part immersed in the tank and feeds the coating composition to a support 9 to receive the coating and is conventionally shown in dashed lines. This comes from a feed and passes successively through a first guide roller 11 and passes between the applicator cylinder 5 covered with the coating composition and one or more counter-cylinders 15 and 17 and, finally, is driven by this cylinder towards a second guide roller 13, after having been coated in passing by the contact of cylinder 5.
- 1 equalizer of the material removed and driven by the applicator cylinder 5 is produced using an equalizing cylinder 19 covered with an envelope of an elastomeric material 21.
- This equalizing cylinder 19 rotates in a direction of rotation which is, in this case, the same as that of the applicator cylinder 5. Its peripheral rotation speed can be of the order of half to an eighth of that of the applicator cylinder 5. [0030] The specific speed chosen is such that good leveling of the coating composition layer is ensured by a smoothing effect.
- the linear (peripheral) speed ratio of the cylinders 5 and 19 which is chosen however depends essentially on the viscosity of this coating composition and, to a certain extent, on the hardness of the envelope of elastomeric material.
- the equalizing effect unlike what is observed when using a doctor blade, causes very little wear on the cylinders, probably due to the rheological effect resulting from the peripheral linear speed differential between cylinders 5 and 19 and this, despite the presence of abrasive charges in the coating composition.
- a suitable device (not shown) can be provided to allow the adjustment of the spacing between the applicator cylinder 5 and the leveling cylinder 19. This leveling effect with very little wear is particularly marked in the case of engravings.
